Coating waste gas filter device

Abstract

The invention relates to the technical field of environmental-protection accessory device, and in particular, relates to a coating waste gas filter device which can remove more granular impurities contained in coating waste gas and improve the filter effect; at the same time, the coating waste gas filter device can remove pungent smell contained in the coating waste gas, prevent direct discharge of the pungent smell from causing harm of human body health and improve the reliability of use; moreover, the coating exhaust gas makes full contact with a filter screen, so the treatment effect of thecoating exhaust gas is improved. The coating waste gas filter device includes a treatment tank; the interior of the treatment tank is transversely provided with the filter screen. The coating waste gas filter device includes a spray tank, a water tank, a spray pump, two groups of spray pipes, a left spray disk, a right spray disk, a purification tank, an upper connecting plate, a lower connectingplate, and a metal net frame; the interior of the metal net frame is filled with an activated carbon adsorbent. The coating waste gas filter device also includes a flow equalizing cover, a pluralityof groups of air outlet nozzles, a left mounting hanging plate and a right mounting hanging plate; the flow equalizing cover is transversely arranged on the upper side of the interior of the treatmenttank, and the input end of the top of the flow equalizing cover is connected with the output end of a gas intake pipe.

Description

technical field [0001] The invention relates to the technical field of environmental protection attachments, in particular to a painting waste gas filtering device. Background technique [0002] As we all know, the painting waste gas filter device is an auxiliary device used to filter the waste gas in the spraying workshop so as to better process the waste gas generated by spraying, and it has been widely used in the field of environmental protection; the existing The coating exhaust gas filtering device includes a treatment box, a filter screen is arranged horizontally inside the treatment box, an air inlet and an air outlet are respectively provided at the top and bottom of the treatment box, and both the air inlet and the air outlet are connected to the inside of the treatment box. An air intake pipe is connected to the air inlet, and an air intake pump is connected to the air intake pipe; when using the existing exhaust gas filter device for painting, first connect the i...

[0002] As we all know, the painting waste gas filter device is an auxiliary device used to filter the waste gas in the spraying workshop so as to better process the waste gas generated by spraying, and it has been widely used in the field of environmental protection; the existing The coating exhaust gas filtering device includes a treatment box, a filter screen is arranged horizontally inside the treatment box, an air inlet and an air outlet are respectively provided at the top and bottom of the treatment box, and both the air inlet and the air outlet are connected to the inside of the treatment box. An air intake pipe is connected to the air inlet, and an air intake pump is connected to the air intake pipe; when using the existing exhaust gas filter device for painting, first connect the input end of the air intake pipe to the spraying workshop, and then turn on the air intake pump to suck the exhaust gas Enter the inside of the treatment box to be filtered through the filter, and then the filtered gas can be discharged through the gas outlet; the existing coating waste gas filter device has been found to contain more particulate impurities in the paint waste gas. The filtering effect of the filter screen is poor; at the same time, the irritating odor contained in the exhaust gas from the coating is directly discharged, causing harm to human health, resulting in low reliability in use; and the contact between the exhaust gas from the coating and the filter screen is not good. Sufficient, resulting in poor treatment effect on painting exhaust gas
