How to choose polyester bag filter in iron and steel plant?
The selection case of 450m3 blast furnace top pulse bag dust collector in iron and steel plant. The pipe jet pulse bag dust collector with 20000 air volume is selected for the blast furnace top pulse bag dust collector. The effect is better. Sufficient filtering area is designed according to the requirements of local or customer environmental protection emission standards to achieve the ideal effect budget design. The blast furnace gas dry pulse bag dust collector is after the waste gas enters the lower box of the bag dust collector through the branch pipe and separated mechanically. The gas passes upward through the cloth bag to attach local dust to the surface of the cloth bag, and the purified air flow converges to the upper box through the cloth bag and enters the hot blast stove for use. After deducting for a period of time, the dust on the surface of the bag is accumulating more and more, and the resistance of the equipment also increases. When reaching a certain value, the electrical control system sends out the ash removal signal, the outlet branch pipe starts, the butterfly valve and the upper ball valve automatically close, the pulse valve opens, the sub cylinder nitrogen is sprayed from the bag mouth through the spray pipe, the bag shrinks rapidly, and the dust on the surface is shaken off and falls into the conical ash hopper.
Blast furnace gas dust collector: it includes a cylinder, which is characterized in that: a filter bag is arranged inside the cylinder, a clean gas chamber is arranged on the upper part of the lattice plate at the top of the cylinder, a clean gas outlet is arranged on the top of the clean gas chamber, pulse back blowing devices are arranged on both sides of the clean gas chamber, a raw gas chamber is arranged at the lower part of the lattice plate at the bottom of the cylinder, an inverted conical temporary ash storage hopper is arranged at the bottom of the raw gas chamber, and a gas flow sharing rectification device is arranged between the temporary ash storage hopper and the raw gas chamber, One side of the top of the temporary ash storage hopper is provided with a raw gas inlet, a diversion device is arranged on the raw gas inlet, and an ash unloading port is arranged at the bottom of the temporary ash storage hopper. The utility model has the advantages that: the volume of the ash hopper of the large-diameter box is fully utilized, and the total project cost of the dust collector is reduced; Evenly distribute the air flow to each space of the dust collector, with simple structure and not easy to wear; It can prevent the air flow from forming vortex and prevent the damaged filter bag from falling into the ash hopper, and can be used as a platform for polyester filter bag inspection and replacement. The most important thing is to choose the right polyester filter bag manufacturer.
The selection cases of pulse polyester bag filter on the top of 450m3 blast furnace in iron and steel plant. The installation cases designed, manufactured and installed by our company are distributed in different sections of iron and steel plant with different filtering area requirements in different regions, which ensures that the dust collected and treated at the same time, can reach an ultra-low standard. A good enterprise will benefit you for life and worry free after sales.
