Abstract

The utility model relates to the technical field of flue gas purification, and discloses a flue gas filter, including a gas collecting pipe, a filtering mechanism fixedly connected to the right side of the gas collecting pipe, and a cleaning mechanism arranged in the filtering mechanism. The flue gas filter is provided with a filter box, a filter screen is fixed in the filter box, and a clean water source is installed in the filter box.

The filtered flue gas floats into the mixing box, and the water pump extracts the mixed medicine from the water storage tank and sprays it out through the atomizing nozzle to neutralize the toxic substances in the filtered flue gas. Through multiple filtering treatments, the flue gas generated by garbage incineration is completely filtered and purified, thereby solving the problem of toxic gases contained in the flue gas being discharged into the air and causing pollution to the environment.

Description

A smoke filter

Technical Field

The utility model relates to the technical field of flue gas purification, in particular to a flue gas filter.

Background technique

Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions to become residues or molten solid substances. Waste incineration facilities must be equipped with flue gas purification devices to prevent heavy metals, organic pollutants, etc. from being discharged into the environmental medium again. Waste incineration is an older traditional method of waste treatment. After the waste is treated by incineration, the reduction effect is significant, land is saved, various pathogens can be eliminated, and toxic and harmful substances can be converted into harmless substances. Therefore, waste incineration has become the main method of urban waste treatment. During the waste incineration process, the flue gas generated often needs to be purified to reduce environmental pollution.

The national patent publication number is: CN219453990U, which discloses a waste incineration flue gas purification device. The application states: "When the existing waste incineration flue gas purification device transmits the waste to the chimney through the induced draft fan, no filtering operation is performed at the air inlet of the induced draft fan, so that when the device is used for a long time, the air inlet of the induced draft fan is too dirty, which reduces the air outlet effect of the induced draft fan, thereby greatly reducing the purification effect of the device." Although the application solves this problem, it has the following defects:

The flue gas purification device filters the flue gas by setting up a filter, but the filter alone cannot completely filter and purify the flue gas generated by garbage incineration. Other toxic gases contained in the flue gas will still be discharged into the air, causing pollution to the environment. At the same time, the filter in the flue gas purification device cannot be cleaned and needs to be replaced frequently, which is more troublesome to operate.

The working principle of the utility model is:

The collecting pipe 1 is fixed on the garbage incinerator, and the fan 208 in the garbage incinerator and the flue gas filter is started. The garbage incinerator burns the garbage inside. The smoke and ash generated during the burning float into the collecting pipe 1. The fan 208 in the L-shaped pipe 204 rotates to absorb the smoke in the collecting pipe 1. The smoke and ash enter the filter box 201 through the L-shaped pipe 204. The filter box 201 is equipped with a clean water source, and the water source floods the filter 207. The smoke and ash are discharged from the bottom pipe opening of the L-shaped pipe 204, and the ash in the smoke is discharged. The embers are wetted by water and float in the water, and are blocked by the filter 207. The filter 207 filters the smoke through the filter 207 to reduce the content of some toxic gases in the smoke. The purified smoke floats from the filter box 201 into the mixing box 203. The input end of the water pump 205 draws the mixed liquid from the water storage tank 202 and discharges it from the fixed water pipe 206 at the output end into the space formed between the top of the mixing box 203 and the baffle plate 210. As the amount of liquid in the space increases, the pressure of the liquid also begins to increase, and finally the liquid is evenly distributed from the atomized spray. The ash is sprayed out from the head 211, and the purified flue gas in the mixing box 203 is purified again, and the toxic gas in the flue gas is neutralized to make the toxic flue gas become non-toxic air, and finally discharged through the exhaust pipe 212. After the water source in the filter box 201 is used many times, it gradually becomes turbid, and some ash will adhere to the bottom of the filter screen 207, affecting the filtering efficiency of the filter screen 207. The servo motor 301 is started, and the output end of the servo motor 301 drives the I-shaped column 303 to rotate. The outer diameter of the I-shaped column 303 is a fixed connecting rope 307. It also moves to the right, pulling the L-shaped block 302, so that the brush 304 on the top of the L-shaped block 302 cleans the surface of the bottom of the filter 207. At the same time, as the connecting rope 307 is pulled, the coil spring 306 gradually extends. When the output end of the servo motor 301 rotates in the opposite direction, the coil spring 306 begins to shrink without being subjected to tension. At the same time, the L-shaped block 302 is pulled to the left, so that the bottom of the filter 207 can be cleaned. When the water in the filter box 201 cannot be used, the valve is opened to discharge the sewage from the drain pipe 209.
