Description

A negative pressure wet dust collector

technical field

The utility model relates to dust removal equipment, in particular to a negative pressure wet dust collector.

Background technique

At present, the wet dust collector generally adopts the positive pressure type, that is, the dusty gas to be treated is firstly sucked by the fan and then discharged into the wet dust removal tower for water spraying treatment. This design has the following disadvantages: because the dusty gas contains A large amount of dust, with a certain amount of large particles, and large objects caused by improper use, or household garbage entering (destructive substances). At this time, when the fan is transporting dust-laden gas into the washing box, the dust, large objects, and household garbage will directly hit the fan blades, causing direct damage to the fan blades. Long-term use will cause damage to the fan and the system cannot operate normally.

Utility model content

The purpose of this utility model is to provide a negative pressure wet dust collector for the above-mentioned defects of the prior art.

In order to solve the above-mentioned shortcomings of the prior art, the technical solution to be solved by the utility model is: a negative pressure wet dust collector, comprising a vertical washing tower and a fan, the vertical washing tower and the fan are connected through pipelines, the The vertical washing tower is arranged with multiple swirl plates at intervals from top to bottom to form multiple spray areas. Each spray area is equipped with a shunt pipe, and each shunt pipe is equipped with multiple spray heads at intervals. The shunt pipe is connected to the water pump through a direct pipe, the upper end of the vertical washing tower is provided with a demisting layer, and the lower end of the vertical washing tower is provided with a drain port, and the drain port communicates with the water tank.

As an improvement of the negative pressure wet dust collector of the utility model, the vertical washing tower is separated by two swirl plates to form two spray areas. After the dust-laden gas enters the spray box from the air inlet, it is diverted by the swirl plate and rises evenly to the spray area for a first spray. The clean gas that has been treated once passes through the second-layer swirl plate, and then performs a second spray. Drenching and washing, after thorough washing, pass through the demisting layer, enter the fan through the pipeline, and finally discharge. This process directly avoids the direct damage to the fan caused by the destructive substances contained in the dusty gas, and greatly prolongs the service life of the fan.

As an improvement of the negative pressure wet dust collector of the present invention, observation ports are respectively provided outside the spray area and the demisting layer. Through the observation port, the gas washing in the spray area and the demisting layer can be observed, which is convenient for controlling the fan.

Compared with the prior art, the utility model has the advantages that: the utility model adopts the swirl plate to divide the vertical washing tower into multiple spraying areas, and the dust-laden gas enters the vertical washing tower from the air inlet and passes through the swirl plate. After the diversion, it rises evenly to the spray area, and performs a spray. The clean gas after the first treatment passes through the second-layer swirl plate, and then performs a second spray wash. After thorough washing, it passes through the demister layer and enters the fan through the pipeline. , and finally discharged. This process directly avoids the direct damage to the fan caused by the destructive substances contained in the dusty gas, and greatly prolongs the service life of the fan.

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below just will further describe the utility model according to accompanying drawing.

As shown in Figure 1, a negative pressure wet dust collector includes a vertical scrubber 1 and a fan 2, the vertical scrubber 1 is connected to the fan 2 through a pipeline 3, and the vertical scrubber 1 is sequentially arranged from top to bottom A plurality of swirl plates 4 are arranged at intervals to form a plurality of spray areas 5, each spray area 5 is provided with a shunt pipe 6, and each shunt pipe 6 is provided with a plurality of spray heads 7 at intervals, and the shunt pipe 6 The vertical washing tower 1 is connected with the water pump 9 through the direct current pipe 8. The upper end of the vertical washing tower 1 is provided with a defogging layer 10, and the lower end of the vertical washing tower 1 is provided with a drain port 11. The drain port 11 communicates with the water tank 12.

Wherein, the vertical washing tower 1 is separated by two swirl plates 4 to form two spray areas 5 . After the dust-laden gas enters the vertical washing tower 1 from the air inlet 13, it is divided by the swirl plate 4 and rises evenly to the spray area 5, where it is sprayed once, and the clean gas that has been treated once passes through the second layer of swirl plate 4 , and then perform secondary spray washing, after thorough washing, pass through the demister layer 10, enter the fan 2 through the pipeline 3, and finally discharge. This process directly avoids the direct damage to the fan 2 caused by the destructive substances contained in the dusty gas, and greatly prolongs the service life of the fan 2 .

Observation openings 14 are respectively provided outside the spraying area 5 and the demisting layer 10 . Through the observation port 14, the condition of gas washing in the spraying area 5 and the demisting layer 10 can be observed, so as to facilitate the control of the blower fan 2.

The working principle of the utility model is: after the blower fan 2 is turned on, the blower fan 2 continuously sucks away the air in the vertical washing tower 1, and a negative pressure state is formed in the vertical washing tower 1, forcing the atmospheric pressure to reduce the content of the dust collection pipe inlet. The dust gas is pressed into the pipeline, enters the vertical washing tower 1 through the pipeline for washing, and rises evenly to the spray area 5 after passing through the swirl plate 4. After being washed twice in the spray area 5, the clean air enters through the pipeline 3 Fan 2, last discharge. The blower is prevented from being impacted by dust and other substances, and the blower 2 is prevented from being damaged due to destructive substances contained in the dusty gas.
