Steel grid plate generally use the carbon steel production, hot-dip galvanizing appearance, can play a role in preventing oxidation. Production of stainless steel can also be used. Steel grid plate with ventilation, lighting, cooling, anti-skid and anti-explosive properties.
The steel grid plate production standards, ChinaYB/T4001-1998;Besides the United States, Britain, Australia and New Zealand also have their own standards. Accordance with the standard steelGB700-88,GB1220-92.
Plate steel lattice-tooth surface to be increased anti-skid performance. Flat steel of the type I also can be produced flat steel.
The steel grid plate production methods: manual machines pressure welding and the production of two. Pressure welding machines use high pressure resistance pressure welding machine, manipulator automatically bar cross on the uniform with a flat steel, through a strong and liquid pressure welding power pressure will be welded into the flat steel bar, which can be solid solder joint, high stability and strength of high-quality steel grid plate. Handmade steel grid in the flat steel plate is the first punching and then bar caving the hole in the spot welding, and the flat steel bar gap exists, but it is impossible to have every point of contact welding, welding is not strong, and strength decrease.
Steel grid plate purposes: petrochemicals, municipal engineering, port engineering, machinery industry, the water plant, steel industry, manufacturing, food processing industry, and other industries have been widely used.
Knitted wire mesh/Wire mesh for flitering liquid and gas/liquid and gas fliter is made of either crochet or knitting of various wire materials including stainless steel, copper, synthetic fiber and other materials.
Wire size: 0.08mmí½0.30mm flat wire or round wire. Single-strand knitted, multi-strand knitted, metal & non-metal (various fibers) knitted wires may be pressed into various specification of corrugated wire as require.
Wire mesh demister, or named wire mesh mist eliminator, is a kind of vapor-liquid separating device. It is widely used in chemical industry, petroleum, vitriol, medicine, light industry, metallurgy, machinery, construction, aviation, sea transportation and environmental protection.
Characters:
1.simple structure, light weight;
2.big rate of porosity, small pressure drop;
3.big contact surface, high efficiency of eliminating mist;
4.convenient to install, operate and repair;
5.long life;
The wire mesh used in wire mesh demister has to be made from gas-liquid filter mesh according to working condition.
Knitted wire mesh/Wire mesh for flitering liquid and gas/liquid and gas fliter is made of either crochet or knitting of various wire materials including stainless steel, copper, synthetic fiber and other materials.
Knitted wire mesh products are applied to those applications including cryogenic, high temperature, corrosive atmosphere, heat conductive, high usage, or special service applications.
knitted wire mesh (or named vapor-liquid mesh, mist eliminating mesh, , shielding metal wire mesh or shielding wire mesh for short), is a kind of wire mesh knitted in particular type. It is used for wire mesh demister, oil-gas separator, dust remover, dedusting apparatus, environmental protection device, various separating and filtering devices, filtering eliminate for auto and tractor, sealing, shock absorption, muffling and purifying components for auto, as well as used for electromagnetic interference and shielding devices for electric apparatus.
Wire size: 0.08mmí½0.30mm flat wire or round wire. Single-strand knitted, multi-strand knitted, metal & non-metal (various fibers) knitted wires may be pressed into various specification of corrugated wire as require.
Wire mesh demister, or named wire mesh mist eliminator, is a kind of vapor-liquid separating device. It is widely used in chemical industry, petroleum, vitriol, medicine, light industry, metallurgy, machinery, construction, aviation, sea transportation and environmental protection, etc.. All imported production equipments for ethane, synthetic ammonia, chemical fiber and so on use wire mesh demister as vapor-liquid separating device. It is mostly used to separate liquid drop with diameter The working principle is as following
When the air with mist rises up at certain speed and gets through wire mesh, mist will collide with wire and will be attached on the surface of wire in the effect of rising inertia. The dispersion and sedimentation makes mist form bigger drop and form a connection point. This drop will become more and more bigger till it is heavier than the composition forces of gas rising force and liquid's surface tensile under the action of wire's wetting property, liquid's surface tensile and wire's capillarity; therefore, liquid drop will be separated and fall off from wire. It nearly doesn't contain mist after gas gets through wire mesh demister.
It improves operation condition, optimizes technical index, reduces equipment corruption, prolongs equipment's life, increases processing capacity, reuses valuable material, protects environment and reduces atmosphere pollution to separate mist from gas
This product is simple in structure, small in size, high in the efficiency of eliminating mist, small in resistance, light in weight, convenient to install, operate and repair. As for the mist with granularity not less than í¦3-5um, its collecting efficiency reaches 98%-99.8%. Pressure slop in which gas gets through demister is very small only 250-500Pa, so
it is good for improving equipment's production efficiency.
