Environment-friendly purification device

Abstract

The invention belongs to the technical field of environment-friendly purification devices, and particularly relates to an environment-friendly purification device which comprises an air inlet pipe, an air outlet pipe, a connecting rod, spiral fan blades, a filter pipe and filter sponge. The filter pipe is fixedly arranged, and the connecting rod is arranged in the filter pipe; the connecting rod is vertically arranged in the filter pipe, the spiral fan blades are fixedly connected to the outer surface of the connecting rod, the air outlet pipe is fixedly connected to the upper end of the connecting rod, and the air inlet pipe is fixedly connected to the lower end of the connecting rod; the filter sponge is arranged on the outer side of the spiral fan blades; the inner wall of the filter pipe is filled with the filter sponge; waste gas is in an acceleration state when passing through a guide pipe, that is, the impact force of the waste gas on a filter screen in a filter screen plate is improved, so that the shaking amplitude of the filter screen in the filter screen plate is larger, dust on the surface of the filter screen is more easily shaken off, the filtering effect is improved, the circulating effect of the waste gas is also improved, and the filtering time of the waste gas is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of environmental protection purification devices, in particular to an environmental protection purification device. Background technique [0002] Flue gas purification mainly refers to the treatment of industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. [0003] In recent years, with the development of industry, more and more factories have been built, and more and more workshop dust and waste gas are produced. In the prior art, the treatment method for dust and waste gas is usually: the dust cover air duct passes through the gravitational force of the fan. Entering the puls...

Problems solved by technology

[0003] In recent years, with the development of industry, more and more factories have been built, and more and more workshop dust and waste gas are produced. In the prior art, the treatment method for dust and waste gas is usually: the dust cover air duct passes through the gravitational force of the fan. Entering the pulse bag filter, under the action of the windshield, the airflow flows upwards and the airflow decreases, part of the large particles of dust are separated out due to inertia and fall into the ash hopper, and the fine dusty gas enters the filter bag in the middle box for filtration and purification , the dust is blocked on the outer surface of the filter bag, the purified gas enters the upper body box through the filter bag mouth and is discharged at a high altitude, and the dust is discharged through the dust discharge valve of the bag filter, but in this process, due to the There is a lot of dust, which is easy to stick to the outer surface of the filter bag, thereby clogging the filter bag, making its filtering effect gradually decrease with the increase of use time. For this problem, the usual method is to replace the filter bag regularly, but this will greatly Increase the production cost of the enterprise, but also consume a lot of manpower and material resources
