Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a high-temperature resistant bag dust collector. Background Art

[0002] The bag dust collector is a dry dust filtering device. The filter bag is made of textile filter cloth or non-textile felt. It uses the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag dust collector, the large particles and high specific gravity dust settle down due to gravity and fall into the ash hopper. The gas containing finer dust is retained when passing through the filter material, so that the gas is purified.

[0003] Given the fineness, high adhesion, and low ignition point of dry dust particles, their accumulation on the surface of dust collector filter bags can easily cause fires in the presence of high-temperature flue gas, burning the filter bags. Therefore, the development of new dust collector bags that offer superior fire and high-temperature resistance, secure installation, and ease of maintenance and removal is urgent, in order to address the performance deficiencies and installation and maintenance challenges of current products on the market.

The cooling device 2 is arranged on the side of the box body 1, the air inlet plate 3 is arranged inside the box body 1, the top of the air inlet plate 3 is connected to the air inlet pipe, and the side of the box body 1 is connected to the air outlet pipe. This setting enables the waste gas to reach the air inlet plate 3 through the air inlet pipe and discharge the dust-removed waste gas from the air outlet pipe. The fixing device 4 is arranged inside the box body 1, the cloth bag 5 is arranged on the surface of the fixing device 4, and the cloth bag 5 is composed of a high-temperature resistant coating, a flame retardant layer, and a refractory layer. The high-temperature resistant coating is a phosphate lead powder coating layer, the flame retardant layer is an aramid flame retardant fiber fabric, and the refractory layer is a glass fiber needle punched felt. This setting makes the cloth bag 5 have good fire resistance, flame retardancy, and high-temperature resistance, and is not easily burned and damaged during use, extending the service life of the cloth bag 5. The fixing device 4 and the cloth bag 5 are each one group and are linearly arrayed at the bottom of the air inlet plate 3. Setting multiple such components can better remove dust from the waste gas.

[0022] The cooling device 2 is composed of an air pump 201, a connecting pipe 202, and an air outlet plate 203. The air pump 201 is fixedly installed on the side of the box body 1, the connecting pipe 202 is fixedly installed at the air outlet end of the air pump 201, the air outlet plate 203 is fixedly installed on the inner wall of the box body 1, the other end of the connecting pipe 202 connected to the air pump 201 is fixedly connected to the air outlet plate 203, and air outlet holes are formed on the surface of the air outlet plate 203.
