A waste gas purification device

Abstract

The invention discloses an exhaust gas purification device, which comprises a box body and a conveying structure. A support leg is arranged at the bottom of the box body, the conveying structure is located at the bottom of the box body and communicates with the inside of the box body, and an exhaust pipe is arranged on the upper part of the side surface of the box body. , the conveying structure includes an input connecting pipe, a first one-way valve pipe and a second one-way valve pipe, both of the first one-way valve pipes are connected with expansion pipes, the input connecting pipe and the second one-way valve pipe The valve pipes are located on both sides of the first one-way valve pipe and are sealed with the expansion pipe; the device drives the telescopic rod to reciprocate through the hydraulic cylinder during transportation, and the gas volume in the expansion pipe changes, which can change the gas during the transportation process. The flow speed, when the expansion pipe connected to the interception pipe shrinks, the gas flows rapidly to the interception pipe, which impacts the interception net in the interception pipe, avoids the blockage caused by too many suspended particles on the interception net during long-term transportation, ensures the transportation efficiency, and Ensure the interception effect of the interception tube on suspended particles.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to an exhaust gas purification device. Background technique [0002] With the development of the economy, the amount of coal is increasing. The existing coal will produce a large amount of gas containing coal gas or coal dust during use, and the temperature of these gases is relatively high. If these gases are not purified, they will be directly discharged to the The air will cause serious air pollution; in the prior art, the purification of exhaust gas generally adopts the spray method, that is, the purification liquid is used to absorb the dust and impurities in the exhaust gas, but the contact between the exhaust gas and the purification liquid is very uneven, As a result, more waste gas still cannot be treated, and the purified waste gas is still not up to standard, wasting more resources.

[0002] With the development of the economy, the amount of coal is increasing. The existing coal will produce a large amount of gas containing coal gas or coal dust during use, and the temperature of these gases is relatively high. If these gases are not purified, they will be directly discharged to the The air will cause serious air pollution; in the prior art, the purification of exhaust gas generally adopts the spray method, that is, the purification liquid is used to absorb the dust and impurities in the exhaust gas, but the contact between the exhaust gas and the purification liquid is very uneven, As a result, more waste gas still cannot be treated, and the purified waste gas is still not up to standard, wasting more resources

[0003] Chinese Patent Publication No. CN108465334A proposes a waste gas purification device. When the water in the water tank overflows from the overflow to the first filter, a layer of water film can be formed on the first filter, and the rotating nozzle is rotating. In the process, the exhaust gas to be purified is sprayed to different positions in the circumferential direction of the first filter element in sequence, thereby providing recovery time for the re-formation of the water film on the same position of the first filter element, so that the exhaust gas from the rotary nozzle is injected into the first filter element. Different positions on the filter can be filtered and purified by the water film all the time, which can improve the purification effect of the exhaust gas. However, in this way, when the exhaust gas purification treatment with a large amount of dust is carried out, it is easy to cause the blockage of the filter element, while the conventional interception method , this kind of problem will also occur, not only affecting the processing efficiency, long-term blockage, but also causing damage to the equipment
