Abstract

An exhaust air purification device for a negative pressure workshop, comprising an exhaust pipe connected to the negative pressure workshop, the end of the exhaust pipe is connected to a dust collector, the dust collector is connected to one end of an outer exhaust channel, and the other end of the outer exhaust channel is connected to a dust removal chamber, Multiple filter elements are arranged on the walls around the dust removal chamber. Compared with the prior art, the technical effect of the utility model is that the utility model is provided with a dust removal chamber on the discharge pipe of the dust removal equipment, and the filter element is fixed on the wall of the dust removal chamber, so that a large amount of fine yeast particles will stay in the dust removal chamber, Less emissions to air.

Description

A negative pressure workshop exhaust air purification device

technical field

The utility model relates to yeast production equipment, in particular to an exhaust purification device for a negative pressure workshop.

Background technique

The production of yeast now requires the crushing of yeast particles. The crushing workshop is a negative pressure workshop according to the needs of the process. Its suction duct will carry small particles of yeast, which will pollute the environment if it is discharged directly into the air. Therefore, there will be a dust collector at the end of the exhaust duct.

Utility model content

The technical problem to be solved by the utility model is: after the dedusting by the dust collector, there will still be finer yeast particles in the discharged air.

The purpose of the utility model is to provide a negative pressure workshop exhaust air purification device, which reduces the discharge of yeast particles to the air.

The technical scheme of the utility model is specifically:

An exhaust air purification device for a negative pressure workshop, comprising an exhaust pipe connected to the negative pressure workshop, the end of the exhaust pipe is connected to a dust collector, the dust collector is connected to one end of an outer exhaust channel, and the other end of the outer exhaust channel is connected to a dust removal chamber, Multiple filter elements are arranged on the walls around the dust removal chamber.

The filter element is located on the upper part of the dust removal chamber.

The filter element is the air intake filter element of the fan.

Compared with the prior art, the technical effect of the utility model is that the utility model is provided with a dust removal chamber on the discharge pipe of the dust removal equipment, and the filter element is fixed on the wall of the dust removal chamber, so that a large amount of fine yeast particles will stay in the dust removal chamber, Less emissions to air.

Description of drawings

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

detailed description

As shown in Figure 1, a negative pressure workshop exhaust purification device includes an exhaust pipe 1 connected to the negative pressure workshop, the end of the exhaust pipe 1 is connected to the dust collector 2, and the dust collector is connected to one end of the outer discharge channel 3 , the other end of the outlet passage 3 communicates with the dust removal chamber 4, and a plurality of filter elements 41 are arranged on the walls around the dust removal chamber 4.

In order to prevent the yeast particles collected in the lower part of the dust removal chamber 4 from blocking the filter element 41 , the filter element 41 is arranged at the top of the dust removal chamber 4 .

The filter element 41 is the air intake filter element of the fan.

which worked originally as:

After the air discharged from the outer exhaust channel 3 enters the dust removal chamber 4, the air flow rate drops far, and the yeast particles carried by it will gradually fall on the lower part of the dust removal chamber 4 (see reference numeral 42), if it still floats in the dust removal chamber 4 , will also be blocked inside by the filter element 41. The air inlet filter element can isolate very small impurities in the air, so the air discharged from the filter element 41 does not contain yeast particles substantially.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those skilled in the art, without departing from the overall concept of the utility model, some changes and improvements can also be made, and these should also be regarded as Protection scope of the present utility model.
