Description

Environmentally friendly and efficient waste gas treatment and purification device

technical field

The utility model relates to a waste gas treatment device, in particular to an environmentally friendly and efficient waste gas treatment and purification device.

Background technique

At present, in many processing and grinding operations, the dust is fine, non-directional, and easy to spread and fly, resulting in serious dust pollution in the operating area. The common treatment measures used to deal with these pollution problems are to build a grinding room to limit the dust from flying out, and at the same time use an exhaust device to extract dust. Dust extraction will generate a large amount of exhaust gas, which will cause environmental pollution if such exhaust gas is directly discharged into the air.

Most of the existing dust removal equipment uses the negative pressure generated by the fan to enter the purifier through the side exhaust outlet and the lower exhaust outlet, and the airflow enters the diversion channel. Under the action of the dust, it falls into the dust collection drawer, and the dust containing fine particles enters the filter chamber, and the dust-containing gas passes through the filter element from the outer surface of the filter bag, and the dust is blocked by the filter element on its surface. When the blocked dust is continuously deposited on the surface of the filter element, The filter element can be cleaned by the structure of the manual dust cleaning machine, and the dust particles deposited on the filter element can be separated from the surface of the filter element and fall into the dust collection drawer under the action of vibration, so that the entire surface of the filter element can be cleaned. , the purified air is discharged from the air duct through the fan. The structure of the filter device in this way is single, and it cannot completely remove the dust effectively from the air entering the purifier, and the dust filtration is not thorough; and the filter element filter device is easy to block, and the filtration efficiency is low; Regular manual processing is required, the cleaning is troublesome, and the degree of automation is low.

Utility model content

The technical problem to be solved by the utility model is that the filter device of the existing dust removal device has a single structure, which cannot completely remove the dust effectively from the air entering the purifier, and the dust filtration is not thorough; and the filter element filter device is easy to block, and the filter efficiency is low; in addition, The precipitated dust is concentrated in the dust collection drawer, which requires regular manual treatment, which is troublesome to clean up and has a low degree of automation. The purpose is to provide an environmentally friendly and efficient waste gas treatment and purification device, which can improve the dust filtering effect and effectively remove dust without causing blockage. The occurrence of the phenomenon improves the filtration efficiency; at the same time, through the double filtration mode, the dust can be completely removed, with a high degree of automation and no need for regular manual processing.

The utility model is realized through the following technical solutions:

An environmentally friendly and efficient exhaust gas treatment and purification device, including a dust removal cylinder, the lower end of which is open and connected to a suction hood, inside the suction hood is provided with a plurality of parallel dust suction pipes and fans, the end of the dust suction pipe and the dust removal cylinder Connected, one side of the dust removal cylinder is connected to the waste gas treatment tank, and a horizontal closing plate is arranged above the waste gas treatment tank, one end of the closing plate is connected to one side of the dust removal tank; the other side of the dust removal tank is hinged with a flip cover, The flip cover is located between the closing plate and the exhaust gas treatment pool.

The filter screen is an upwardly convex curved filter screen, which can increase the contact area with the air and improve the filtering efficiency and effect.

There are multiple spray heads on the inner wall of the dust removal cylinder above the closed plate. There is a cavity in the filter screen, and the cavity is filled with active adsorption materials. Water mist is sprayed through the spray heads, which can filter the air after the initial filtration. The dust in the filter is humidified and finally absorbed by the material filled in the filter, which further improves the filtering effect.

The bottom plate of the waste gas treatment tank is inclined, and the end of the bottom plate close to the axis of the dust removal cylinder is inclined upwards, which guides the air drawn out by the suction hood so that it can move upwards smoothly from the side of the waste gas treatment tank.

The waste gas treatment tank is provided with a water outlet and a water inlet, and the water outlet and the water inlet are connected to the circulating water pump. The degree of automation is high, and the water in the pool is automatically replaced and utilized.

The tail ends between two adjacent dust collection pipes merge into the same converging pipe. There are multiple dust collection pipes to increase the dust collection area of the dust collection hood, but it will cause the air in each pipe to be too scattered, so every The air in the two suction pipes is merged into a confluent pipe, which can improve the concentration of dust in the air.

The detachable link between the dust collector and the suction hood is convenient for disassembly, replacement and cleaning.
