Description

Technical Field

[0001] The invention belongs to the technical field of graphite manufacturing, and in particular relates to a workshop dust removal system. Background Art

There are many leakage points, large dust, and it is difficult to clean up, which can easily affect the human respiratory system. The overall dust removal in the plant is due to the high height of the large workshop and the harsh on-site environment. The existing workshop dust removal system has a small dust removal function, cannot meet the dust removal needs, and is easily damaged. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a workshop dust removal system which has a large dust removal function, can meet the dust removal needs, is not prone to damage, and has a long service life.

[0004] The purpose of the present invention and the solution of its main technical problems are achieved by adopting the following technical solutions: A workshop dust removal system of the present invention comprises an induced fan, a dust collector, a water washing tower, a ventilator, a high-pressure centrifugal fan, a steam-water separator, an air outlet duct, and a dust collecting air distribution device, and is characterized in that the induced fan is connected to the high-pressure centrifugal fan through a pipeline, the high-pressure centrifugal fan and the ventilator are connected to the air outlet duct, the ventilator is connected to the steam-water separator through a pipeline, the steam-water separator is connected to the water washing tower through a pipeline, the water washing tower is connected to the dust collector through a pipeline, and the dust collector is connected to the dust collecting air distribution device through a pipeline.

[0005] The induced fan comprises an inner cylinder installed in an outer cylinder, an air mixing chamber is arranged between the outer cylinder and the inner cylinder, a nozzle is arranged between the top of the outer cylinder and the top of the inner cylinder, an air inlet pipe is installed on the outer cylinder, and the air inlet pipe is connected to the air mixing chamber.

[0006] The top end of the outer cylinder is provided with a convex head.

[0007] The top end of the inner tube is provided with a convex head, and a nozzle is formed between the convex head provided at the top end of the inner tube and the convex head provided at the top end of the outer tube.

[0008] The induced fan is installed in a closed factory building, the closed factory building is connected to the dust collecting air distributor, and one end of the air outlet pipe is inserted into the closed factory building.

[0009] Compared with the prior art, the present invention has obvious beneficial effects; it can be seen from the above technical scheme that: the induced fan is connected to the high-pressure centrifugal fan through a pipeline, the high-pressure centrifugal fan and the ventilator are connected to the air outlet pipe, the ventilator is connected to the steam-water separator through a pipeline, the steam-water separator is connected to the water washing tower through a pipeline, the water washing tower is connected to the dust collector through a pipeline, and the dust collector is connected to the dust collecting air distributor through a pipeline. The overall air of the workshop is driven to the induced air distributor, and then after filtering, pressurization and other measures, the gas is returned to the closed factory building. Clean compressed air is sent into the factory building through a pipeline to achieve the effect of overall filtering of the factory building. The induced fan is installed with an inner cylinder in the outer cylinder, and there is a mixed air chamber between the outer cylinder and the inner cylinder, and there is a nozzle between the top of the outer cylinder and the top of the inner cylinder. The air compressor compresses air outside the large workshop, and the compressed air enters the mixed air chamber through the air inlet pipe. The air inlet pipe and the outer cylinder are at an angle of 45 degrees, which is convenient for the compressed gas to quickly enter the mixed air chamber. And the pressure is quickly increased in the mixed air chamber. As the pressure increases, the speed at which the compressed gas is blown out of the directional nozzle gradually increases. When the pressure in the air mixing chamber reaches the highest, the wind speed of the directional nozzle reaches the maximum. An annular air flow will be formed at the tail of the outer cylinder. According to the Bernoulli principle and fluid mechanics, the air inside the annular air flow will be driven forward with the air flow, and the air outside the annular air flow will also be driven forward. Negative pressure areas will be formed inside and at the front end of the inner cylinder, and new gas will be attracted in. According to measurements, the air flow driven by the annular air flow is fifteen times the air flow ejected from the directional nozzle, greatly improving the overall space gas flow efficiency. It is used for dust removal in workshops with high conductive dust, high corrosion or special explosion-proof requirements. When dealing with high-corrosion workshops, the water scrubber can be replaced with the corresponding acid and alkali solvents. The dust collector is a universal HMC series pulse bag dust collector, the water washing tower is a TBR type water washing tower, and the steam-water separator is an SD-4 type. Their function is to remove water vapor from the air, thus achieving a large dust removal function for the workshop dust removal system, meeting the dust removal needs, and not prone to damage and having a long service life.
