The double wall plate heat exchanger plate is welded integrally with two thin plate pieces along the corner hole of each pair of plates. When the plate leaks, for example, the perforation caused by long time working will be easily detected from outside. Thereby it stops mixing between two materials.And at the same time, they plays very important roles towards warning internal leakage. Combined with the double seal of the gasket, the possibility of mixing two materials is avoided, and it is suitable for applications with high sanitary requirements or high safety and reliability of industrial production. Since the two sheets are welded to form a sheet, the heat transfer coefficient is inevitably lowered, but the highest safety is achieved in preventing materials mixing.

Tubular exchanger is the most widely used heat exchanger on chemical and alcohol production. It is mainly composed of shell, tube plate, heat exchange tube, head, baffle and so on. Required material, can be made of ordinary carbon steel, copper, or stainless steel. During heat exchange, a fluid enters through the connecting pipe of the head, flows in the pipe, and flows out through the outlet pipe at the other end of the head. Another fluid enters by the nozzle of the shell and flows out from another nozzle on the shell. This is called the shell process. The structure of the tube heat exchanger is simple, compact and cheap, but the outside of the tube can not be cleaned mechanically. The heat exchanger tube bundle is connected to the tube plate, which is welded to both ends of the shell respectively, and is connected to the top cover. The top cover and the shell are provided with a fluid inlet and outlet pipe. A series of baffles perpendicular to the tube bundle are usually arranged outside the tube. At the same time, the connection between tube and tubesheet and shell is rigid, while outside the tube are two kinds of fluid with different temperature. Therefore, when the temperature difference between the tube wall and the shell wall is large, due to the thermal expansion of the two are different, a large thermal stress is generated, so that the tube twists or loosens the tube from the tube plate, or even destroys the heat exchanger.
Brazed heat exchanger is an evolution of detachable heat exchanger, the sealing material is changed from rubber pad to copper, and all the plates are combined together by copper solder. Brazed plate heat exchanger is one of the new equipment in the field of heating and cooling. Brazed heat exchanger does not have sealant pad, all the plates are made of high temperature melted and welded copper foil, the plate has a unique herringbone corrugated design, can make the fluid in low flow rate also achieve the effect of turbulence, heat transfer efficiency is high, brazed plate heat exchanger sizing is usually small, mainly used in high temperature and high pressure, rubber pad can not adapt to the working conditions. It also has certain disadvantages, brazed heat exchanger can not be separated to clean, can not be repaired, the price is slightly higher.
The plate heat exchanger is composed of a set of corrugated metal plates with four corner holes for the passage of two liquids for heat transfer. The metal sheet is mounted in a frame having a fixed plate and a movable pressing plate on one side and clamped by a clamp bolt. A gasket is placed over the plate to seal the fluid passages and direct fluid flow alternately into the respective passages to form a heat exchange. The flow, physical properties, pressure drop and temperature difference of the fluid determine the number and size of the plates. The corrugation of the plate not only increases the degree of turbulence but also forms a number of support points sufficient to withstand the pressure difference between the media. The metal plate and the movable compression plate are suspended on the upper guide bar and positioned by the lower guide bar, while the rod end is fixed on the support. On the column, but if one or both of the liquids pass through the heat exchanger more than once, the interface should be on the fixed plate and the movable compression plate. In most cases, one-way is used, and all the pipes are connected to the fixed platen. On, check the shoes to open the heat exchanger without disassembling the pipe.
Product introduction The plate condenser consists of plates that are welded together in pairs to form a so-called plate set. The concept of a plate set leads to two different types of channels: a weld channel for condensing steam and a gasket seal channel for cooling water. This type of plate is specially designed for optimum condensation. It has an asymmetrical arrangement with a large gap on the steam side and a small gap on the cooling water side. This makes it possible to maintain a very low pressure drop at the steam end while maintaining a certain speed and turbulence on the cooling water side. This maximizes heat transfer efficiency and minimizes fouling. Plate condensers are specially developed for condensing steam under low pressure or vacuum conditions in evaporation and distillation systems. It can meet a variety of specific applications and capabilities requirements. The steam inlet fitting is large and the two condensate outlets are small. The cooling water fitting is a medium size and is located in the center of the plate. Maximum heat transfer area: 500m2/set; Maximum design pressure:16bar Maximum temperature:200 celsius degree; Nozzle diameter:DN50~DN700 Plate thickness:0.5mm-1.2mm; Gasket material:NBR, EPDM, HNBR, HT-NBR, HEPDM, CR, VITON/FKM Fixed and movable plate material: Carbon Steel, Stainless Steel, and others on request. Plate material:AISI304, AISI316, AISI316L, Titanium, Ti-Pa,Hastelloy C276,254SMO,Nickel, AISI904L. Features Plate condenser Lower cost Due to the high heat transfer efficiency, this means less heat exchange area and higher cost efficiency than conventional shell and tube type, especially when stainless steel or titanium is required. The compact design also saves space, thus reducing transportation and installation costs. Plate condenser Less fouling Due to the high strength turbulence created by the specially designed corrugated sheets, there is less fouling on the cooling water side than the shell and tube condenser. Plate condenser Easy to clean The cooling water side is easy to clean, whether in the way of mechanical or chemical. Plate condenser Easy to expand Just add an extra "plate group" in the existing frame. Plate condenser Complete counterflow A greater degree of subcooling of non-condensable gases can be achieved compared to shell and tube equipment. Therefore, the load of the vacuum pump will be reduced. Range of application Alumina, food industry, sugar industry, beverage industry, industrial wastewater, etc.
Product principle The working principle of the plate evaporator is to compress the secondary steam generated by the equipment through the configured compressor, then raise the pressure and temperature to a certain range, and finally transfer it to the relevant heating chamber of evaporator as heating steam. Finally, to perform the condensation heat release program, so that it can help the latent heat of the steam and the recycling can be effectively obtained.

Advantages Plate evaporator High heat transfer efficiency The plate evaporator is ingenious in design, so the heat transfer efficiency is higher than that of the general evaporator. Generally, the plate evaporator area only needs about one-half of the tube evaporator then can achieve the same evaporation effect. Plate evaporator Compact overall structure The whole structure is compact, floor space is small, and there is no need to invest too much manpower and material resources in the later use process. For some maintenance work, it only needs to be carried out in the original space range, and it's very simple whether it is disassembled or installed . Plate evaporator Diversification of components The heat exchange area can be effectively adjusted according to the customer's needs: now the heat exchange area of different evaporators has different ranges, since the heat exchanger plates can be disassembled, so multiple components with multiple skills and more new functions can be provided through adjusting number of plates and changing relative flow path. Plate evaporator Small heat loss Because this type of equipment is compact in structure and relatively light in weight, compared with tubular evaporators, it also reduces heat loss, and such equipment usually does not need to be insulated. Plate evaporator Less pressure loss Under the same heat transfer coefficient condition, such evaporator equipment can control the pressure loss within a certain range by rotating a reasonable flow rate.Compared with tubular evaporator,it can reduce 2/3 pressure loss. Plate evaporator Stable and safe operation Different sealing procedures are designed on the sealing device between the plates, and Range of application Metallurgy, food industry, paper industry, air conditioning, chemical and desalination industries

Plate heat exchanger High heat transfer coefficient The design of the plate corrugation is aimed at the high thermal conductivity. The special flow path are formed by the plate corrugation causing strong disturbance flow at a very low flow rate, which is called turbulent flow. And the disturbance flow can be self-cleaning to prevent fouling and thus the heat transfer efficiency is high. Plate heat exchanger Large logarithmic temperature difference The temperature difference at the end is small, and the plate heat exchanger is mostly a cocurrent or countercurrent type of flow. In addition,there's no bypass flow. Plate heat exchanger Small footprint and easy maintenance The plate heat exchanger has a compact structure, and the heat exchange area per unit volume is 2-5 times that of the shell-and-tube type, and the floor area of the plate heat exchanger is about 1/2-1/3 of the shell - tube heat exchanger when achieving same heat exchange capacity .
