Description

A pulse dust collector

technical field

The utility model relates to the technical field of industrial dust removal, in particular to a pulse dust collector.

Background technique

Dust refers to solid particles suspended in the air, and dust will be generated in the production links of feed production, such as conveying, mixing, crushing, screening, and packaging. In feed production, dust is a harmful substance, and its main hazards include the following aspects: destroying the air environment and affecting people's vision; causing adverse effects on product quality and increasing equipment wear; damaging human health, leading to pneumoconiosis, Cancer; cause fire or even explosion. Therefore, in production, it is very important to eliminate dust in time.

The pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of the bag filter, which removes the dust attached to the filter medium by blowing compressed air. It has the advantages of stable performance, low operating cost, high purification efficiency, and recyclable dust, so it is widely used in the dust treatment process of industrial enterprises. The existing pulse bag filter generally has the problem of dew condensation on the filter bag, and the dew condensation refers to the phenomenon that the humid air precipitates saturated moisture under a certain temperature and pressure. Once the filter bag condenses, serious dust can be hardened on the filter bag, blocking the filter holes, resulting in an increase in the resistance of the dust collector until it fails. Therefore, dew condensation on the filter bag of the pulse dust collector should be avoided.

The utility model aims to solve the deficiencies of the prior art, and provides a pulse dust collector, which can prevent the filter bag from condensation.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a pulse dust collector, including a high-pressure air source, a water separation filter, an air dryer, an air heater, a pulse valve, a PLC, a high-pressure air pipe, an upper box, Partition board, dust hopper, filter bag, filter bag support frame and fan, the partition board is arranged horizontally in the upper box, and divides the upper box into a clean room and a dust room, and the filter bag support frame is vertically evenly distributed in the upper box. On the lower surface of the partition, the filter bag is set on the filter bag support frame. There are round holes corresponding to the filter bag support frame on the partition plate. The high-pressure air pipe is inserted into the clean room horizontally. One corresponding nozzle, the side wall of the clean room is provided with an exhaust pipe, the exhaust pipe is connected to the fan, the fan is driven by a motor, the pulse valve is located outside the upper box, one end of the pulse valve is connected to the high-pressure air pipe, and the other end is connected to the air heater Connection, the air heater is connected to the air dryer, the air dryer is connected to the water separation air filter, the water separation air filter is connected to the high-pressure air source, a temperature sensor A is installed between the air heater and the air dryer, and dust accumulation The hopper is arranged under the upper box, the side wall of the dust collecting hopper is provided with an air inlet pipe, the outer wall of the air inlet pipe is provided with a temperature sensor B, the inner wall of the ash collecting hopper is provided with a baffle, and the baffle is arranged obliquely downward to block the air inlet. The PLC is set on the outer wall of the upper box, and the temperature sensor A, the temperature sensor B, the air heater and the pulse valve are all connected with the PLC circuit.

The driving motor of the fan is a two-pole motor.

The ratio of the air intake air volume of the fan to the exhaust air volume of the exhaust pipe is 1.15:1.

The beneficial effects of the utility model are: the high-pressure gas provided by the high-pressure air source of the utility model passes through the water separator, the air dryer, the air heater, and the high-pressure air pipe, and finally sprays into the filter bag from the nozzle to remove the dust on the filter bag. Dust accumulation, the high-pressure gas is dried and heated to avoid condensation in the filter bag; temperature sensor A and temperature sensor B monitor the temperature of the high-pressure gas and the outside air respectively, and transmit the data to the PLC, and the PLC controls the air according to the temperature difference between the high-pressure gas and the outside air The heating power of the heater to the high-pressure gas can control the temperature difference between the high-pressure gas and the outside air within the set range, making the possibility of dew condensation on the filter bag lower; the baffle can directly block the coarse dust particles, making them directly Fall into the ash hopper.
