Description

Technical Field

[0001] The utility model relates to the technical field of filter structures, in particular to an exhaust gas pre-treatment filter structure. Background Art

[0002] With the continuous development of industrial production, more and more companies have achieved automated or semi-automated production. In the production process, more or less waste gas is discharged. In order not to affect the environment, the discharged waste gas needs to be pre-treated first. The pretreatment of waste gas includes filtering the waste gas to remove pollutants such as solid particles, oil mist and humidity in the waste gas.

[0003] Existing exhaust gas pretreatment filtration usually uses a filter plate to filter particulate matter in the exhaust gas, and then passes the preliminarily filtered exhaust gas into water to filter out tiny particles and water-soluble substances in the exhaust gas. When the exhaust gas is directly passed into the water, the bubbles generated by the exhaust gas in the water are larger and the contact area with the water is smaller, resulting in poor filtering effect of some tiny particles and water-soluble substances, and the particles accumulate on the surface of the filter plate. After long-term use, the particles can easily clog the filter plate, making it inconvenient to clean the filter plate. Utility Model Content

[0004] The purpose of the utility model is to provide an exhaust gas pre-treatment filtering structure to solve the problems raised in the above background technology.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Exhaust gas enters through the air inlet pipe and moves upward along the spiral plate. Some solid particles are adsorbed on the frosted protrusions on the surface of the spiral plate. Then the exhaust gas is filtered by the filter plate and flows into the water above the partition through the air nozzle. The rotating shaft drives the crushing rod to rotate, breaking up the large bubbles generated by the exhaust gas, increasing the contact area between the exhaust gas and the water, thereby increasing the movement path of the exhaust gas through the spiral plate and improving the filtering effect on the exhaust gas particles. Then the preliminarily filtered exhaust gas is passed into the water to filter the tiny particles and water-soluble substances in the exhaust gas, and the bubbles generated by the exhaust gas are broken up, so that the exhaust gas contacts the water in the form of tiny bubbles, increasing the contact area with the water and improving the filtering effect on tiny particles and water-soluble substances.

[0015] 2. The motor rotates, driving the shaft to rotate. The brush plate brushes across the surface of the filter plate, brushing off the solid matter adhering to the surface of the filter plate, maintaining the filtering effect of the filter plate, making it easier to clean the filter plate after filtration to prevent the filter plate from being blocked by particles after long-term use.

[0016] 3. After the exhaust gas treatment is completed, turn the reversing valve to pump water into the annular tube below and spray it out from the atomizing nozzle. The water flushes the filter plate and the spiral plate at the same time, cleaning both of them, increasing the cleaning effect of the filter plate and facilitating the unified discharge of the filtered medium.
