For steel plant: In steel making enterprises, the flue gas from arc furnace is one of the main source of pollution, as the exhausting volume is large, the temperature of flue gas is high and it is fine ash powder with hydrophilic property. It is difficult to collect and filter. Along with the development of process in steel and iron industry with ultra high power, strengthening melting and molten iron, and the environment protection, the flue gas filtering is the key section in steelmaking workshop. According to your workshop layout and local gas exhausting code, you can select our different type of dust collection system, such as â??sealed cover/ roof coverâ?? + the fourth flue gas outlet hole + cooler + separately chamber back blowing bag type filter or pulse bag type filter. For submerged arc furnace During the alloy melting process in submerged arc furnaces, there is large volume of flue gas with high temperature. Also, the composition of flue gas is very complex. Considering the chemical and physical properties of flue gas, you can select the best one for your project. In recent years, the LCM long bag type pulse filter has been wide applied for submerged arc furnaces. It can be also used for calcium carbide furnace, boiler, limestone kiln, metal mixer and asphalt mixing station to meet the requirement of national emission standard. For raw material and crashing workshops: The raw material for melting should be crashed, screening and transporting to the furnace. During these productions, certain dust will be caused. In the products workshop, there is same problem of dust from crashing and screening. For example, the particles of titanium ore and slag are very fine, it is easy to make the pollution in the workshop and harm to workers. The dust collection system for raw material and crashing workshop, it will be including cover, tube, filter, blower and ash vessel, etc. The processing as follows: The ash powder will be collected and treated. The clean gas will be emitted to atmosphere. The fume will be separated. The fume will flow to the filter by the action of blower. Fume cover will be collected the dust from operation

Road Blocker As a barricade blocking the vehicle which enters a building by force, it rises and falls with hydraulic power. It is a cutting edge system of blocking the entry of vehicles, and can normally work after collision with a vehicle. Characteristics Roadblock can operate alone, and be used to prevent forcible intrusion at the gateway of vehicles by being installed with other devices, such as gates. When working, it takes 4secs for a blocking screen to work up to 659mm(Max Height), and having the noticeable paint and warning lights installed, the approaching vehicles can stop in time. When the blocking screen falls, as its height is the same as the road surface, it doesn't interrupt the flow of traffic. As an option, it is possible to coat the surface of blocking screen with the same materials as the road surface.
