Description

A pulse dust collector

【Technical field】

The utility model relates to a pulse dust collector.

【Background technique】

Because many existing factories will produce a lot of dust during processing. Especially in chemical plants that process chemical raw materials, there is a lot of raw material dust. If it is directly sucked away by the exhaust fan, it will pollute the environment and waste raw materials.

The utility model is made under such circumstances.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a pulse dust collector which can collect dust raw materials and purify the working environment.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A pulse dust collector, which is characterized in that it includes a bin body with negative internal air pressure, an inlet for dust-containing air to enter on the bin body, a dust outlet valve at the outlet at the bottom of the bin body, and a dust outlet valve at the bottom of the bin body. The upper part is provided with an air extraction port, and a plurality of filter bags and pulse air pipes connected with high-pressure pulse gas are arranged on the warehouse body. One end protruding from the warehouse body is provided with a pulse air valve.

A pulse dust collector as described above is characterized in that the filter bag is cylindrical.

A pulse dust collector as described above is characterized in that the number of said filter bags is 2-5.

Compared with the prior art, the utility model has the following advantages:

The utility model adopts a negative pressure bin body to collect dust, and then the dust will be attached to the filter bag, and then the pulse air pressure is blown to the filter bag, so that the dust falls to the bin body, which not only purifies the air, but also collects the dust Function, collecting these dust raw materials can also be reused.

【Description of drawings】

Fig. 1 is a schematic diagram of the principle of the utility model.

【Detailed ways】

The utility model is described in detail below in conjunction with accompanying drawing:

As shown in the figure, a pulse dust collector includes a bin body 1 with a negative internal air pressure, and the bin body 1 can be arranged in various shapes as required. The bin body 1 is provided with an inlet 2 for the air containing dust to enter, and the inlet 2 can be arranged on the top or side of the bin body 1 .

The outlet at the bottom of the bin body 1 is provided with a dust outlet valve 3 . An air suction port 4 is arranged on the top of the warehouse body 1, and the air suction port 4 is connected with a suction fan. A plurality of filter bags 5 and a pulse air pipe 6 connected with high-pressure pulse gas are arranged on the chamber body 1 . The opening at the upper end of each filter bag 5 is connected with the opening of one end of the pulse air pipe 6 extending into the warehouse body 1, and the end of the pulse air pipe 6 extending out of the warehouse body 1 is connected to the high-pressure air pipe, and the pulse air pipe 6 is provided with a pulse Gas valve 7.

As a preferred mode of this embodiment, the filter bag 5 is cylindrical.

As a preferred mode of this embodiment, the number of filter bags 5 is 2-5.

The working process is as follows: due to the negative pressure in the chamber body 1, the dust-containing air will be sucked into the chamber body 1, and due to the sudden expansion of the cross-sectional area of the air flow, the flow rate will decrease, and some dust with relatively large particles will directly fall into the chamber body 1. bottom. The dust with relatively small particles will settle on the surface of the filter bag 5 and form a dust layer through the comprehensive effects of inertia, collision, interception and static electricity on the surface of the filter bag 5, and the purified air will be discharged from the air outlet 4 to the outside world.

When the dust attached to the surface of the filter bag 5 is enough, the pulse air valve 7 will act, and the high-pressure gas will rush into the filter bag 5. Under the action of the high-pressure gas, the dust attached to the surface of the filter bag 5 will fall into the bin body together. 1. At the bottom, the pulse period of the pulse valve 7 can be adjusted according to the actual situation.

When there is enough dust in the bin body 1, the dust outlet valve 3 can be opened to collect the dust for reuse.
