Technical Field
The utility model relates to an environmental protection machinery, concretely relates to gas drainage dust collector.
Background
With the development of modern industry, the influence of industrial dust on environmental pollution and human health is increasingly serious, and dust with a certain concentration in air has high-risk and high-explosion risks and must be treated in time. The existing dust removing equipment provides suction force through an electric fan, industrial dust is sucked into a dust removing bag or other devices, and due to the fact that the existing dust removing equipment works by electrifying, sparks are easily generated to detonate the dust, so that the existing dust removing equipment is not suitable for being used in places with high dust content in the air.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the dust in a high-concentration dust place is processed in time, the dust concentration is reduced, and the high-level high explosion risk is reduced.
In order to solve the problem, the utility model adopts the following technical scheme: a gas drainage dust removal device comprises a dust removal cover and a negative pressure pipeline communicated with the top of the dust removal cover, wherein at least one positive pressure pipeline is communicated with the side wall of the bottom part adjacent to the dust removal cover, and the gas outlet of a gas storage tank for storing positive pressure gas is connected with the gas inlet of the positive pressure pipeline (preferably, a pressure reducing valve is arranged between the gas outlet of the gas storage tank and the positive pressure pipeline); when the negative pressure gas storage tank is used, positive pressure gas is sent into the dust hood through the positive pressure pipeline, the gas is discharged from the negative pressure pipeline, and negative pressure is formed in the dust hood; this negative pressure makes the dust excluding hood is inhaled to the dust excluding hood below to discharge through the negative pressure pipeline, the device simple structure, practicality need not the circular telegram, are applicable to the high risk place of high concentration dust.
Further preferred scheme is, the malleation pipeline is a plurality of, and evenly distributed is in on the bottom lateral wall of dust excluding hood, rationally set up one or more malleation pipeline, increase the gaseous air input of malleation, further improve dust absorption effect.
Further preferred scheme is that the gas inlet end of gas holder is connected with positive pressure air pump or malleation pipeline, sets up through this overall arrangement, has guaranteed dust collector's normal continuous use, and dust collector does not directly circular telegram work simultaneously, has guaranteed dust disposal's security.
The further preferred scheme is that the bottom of dust excluding hood is the bellmouth of downward extension, and the setting of this shape has improved the inspiratory capacity of dust, has improved the treatment effeciency of dust.
Further preferably, the dust hood is cylindrical or cubic, and the shape of the dust hood is adjusted according to the field size of a dust place, so that the dust hood is simpler and more convenient to install.
Further preferably, the positive pressure gas in the gas storage tank is inert gas, so that the content of oxygen in the dust treatment process is reduced, and the risk of dust explosion is further reduced.
The utility model discloses simple structure, dust absorption effect is good, and the device uses without the circular telegram, combines the gaseous use of inertia malleation, has reduced the dust explosion risk, is applicable to the higher place of dust concentration in the air, has improved the security in place.

Detailed Description
Example 1
Referring to fig. 1, a gas drainage dust removing device comprises a dust removing cover 3 and a negative pressure pipeline 4 communicated with the top of the dust removing cover 3, wherein at least one positive pressure pipeline 2 is communicated with the side wall of the bottom of the dust removing cover 3, and a gas outlet of a gas storage tank 1 for storing positive pressure gas is connected with a gas inlet of the positive pressure pipeline 2; when the gas storage tank is used, positive pressure gas is sent into the dust hood through the positive pressure pipeline 2 by the gas storage tank 1, the gas is discharged from the negative pressure pipeline 4, and negative pressure is formed in the dust hood 3; the negative pressure enables the dust 7 below the dust hood 3 to be sucked into the dust hood 3 and discharged through the negative pressure pipeline 4, and through the change of gas pressure, drainage airflow is formed in the dust hood 3; the bottom of dust excluding hood 3 is the bellmouth of downward extension, and the setting of this shape has improved the inspiratory capacity of dust, has improved the treatment effeciency of dust.
As almost all dust concentration in the air exceeds the standard and is easy to cause explosion, such as starch, aluminum powder and the like, a positive pressure air pump or a positive pressure pipeline is connected to the air inlet end of the air storage tank 1, the arrangement ensures the normal and continuous use of the dust removal device, and meanwhile, the dust removal device is not directly electrified to work, thereby ensuring the safety during dust treatment; the positive pressure gas in the gas storage tank 1 is preferably inert gas, such as nitrogen with lower cost, so that the content of oxygen in the dust treatment process is reduced, and the risk of dust explosion is further reduced.
The working principle is as follows: positive pressure gas in the gas storage tank 1 enters the dust hood 3 through the positive pressure pipeline 2 and is discharged through the negative pressure pipeline 4, the positive pressure gas and the negative pressure gas are intersected to form gas flow, the gas flow discharged to the negative pressure pipeline 4 is formed by utilizing the principle of air pressure difference, auxiliary dust 7 is guided to enter the dust hood 3 and is discharged along with the negative pressure pipeline 4.
The preferred scheme is as follows: a pressure reducing valve is arranged between the air outlet of the air storage tank and the positive pressure pipeline.
The utility model has the advantages that: the novel dust collector is simple in structure and good in dust collection effect, is not electrified for use, and meets the dust collection requirements of places with high dust concentration and high risk of high risk and high explosion; the principle that air flow is formed by utilizing air pressure difference, dust is absorbed by utilizing the air flow, and meanwhile, the use of inert gas is combined, so that the explosion risk of dust is reduced, and the dust collector is suitable for places with high-concentration dust.
The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
