Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a gas filtering device of a waste gas treatment system. Background Art

[0002] Cement kiln co-processing of solid waste production lines refers to a technology that utilizes existing cement production facilities to treat solid waste. This method converts solid waste into raw materials for cement production while reducing its environmental impact. In recent years, air pollution prevention and control has garnered widespread attention, and waste gas treatment has received significant attention across various industries. However, effective treatment systems are often costly and difficult to operate and maintain, making them difficult to implement. Simple waste gas treatment systems also struggle to ensure that treated gases meet emission standards.

[0003] However, the existing treatment scheme generally adopts spray washing, which does not allow sufficient contact between the spray liquid and the exhaust gas, easily resulting in uneven treatment of the exhaust gas and certain defects. Therefore, it is necessary to propose a gas filtration device for the exhaust gas treatment system. Utility Model Content

[0004] The utility model aims to solve the shortcoming in the prior art that the contact between the spray liquid and the waste gas is not sufficient, and proposes a gas filtering device for a waste gas treatment system.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A gas filtering device of an exhaust gas treatment system includes a separator mechanism, a dust removal mechanism, a purification mechanism and an adsorption mechanism. The separator mechanism, the dust removal mechanism, the purification mechanism and the adsorption mechanism are connected to each other in sequence. The dust removal mechanism includes a dust removal box. A filter bag is fixedly installed in the dust removal box. A sliding column is fixedly installed at the center of the top of the filter bag. The sliding column slides through the top of the dust removal box. A driving assembly for driving the sliding column to move up and down is provided at the top of the dust removal box. A limiting ring is fixedly installed on the top of the sliding column. A functional spring is sleeved on the sliding column. The functional spring is elastically connected between the top of the dust removal box and the bottom of the limiting ring.

[0007] Preferably, the drive assembly includes an L-shaped mounting plate, the L-shaped mounting plate is fixedly mounted on the top of the dust removal box, a drive motor is fixedly mounted on the bottom surface of the horizontal section of the L-shaped mounting plate, a fixed rack is fixedly mounted on the top of the sliding column, the output shaft of the drive motor is coaxially fixedly connected to a sector gear, and the sector gear is meshed with the fixed rack;

[0008] It is used to shake the filter bag to prevent the filter bag from being clogged by low-diameter particles. When the filter bag is filtering the gas, the drive motor is started, and the drive motor drives the sector gear to rotate. When the sector gear cooperates with the fixed rack, the fixed rack drives the sliding column to move upward. When the sector gear is disengaged from the fixed rack, the dead weight of the sliding column and the fixed rack causes the sliding column to move downward. As the sliding column moves up and down, the filter bag is shaken, thereby shaking the filter bag to prevent the filter bag from being clogged by low-diameter particles. When the sliding column moves up and down, the functional spring is pulled up or compressed to prevent the sliding column from moving too much.

[0009] Preferably, the separator mechanism comprises an inverted conical separation cylinder, the top of the outer wall of the conical separation cylinder is connected to an air inlet, the top of the inverted conical separation cylinder is connected to a first connecting pipe, and the bottom of the inverted conical separation cylinder is provided with a discharge port;

[0010] The inner side wall of the air inlet is tangent to the top of the inner side wall of the inverted conical separation cylinder, the other end of the first connecting pipe is connected to the dust removal box, and the end of the first connecting pipe is arranged below the filter bag;

[0011] It is used to separate large solid particles in exhaust gas. Exhaust gas enters the conical separation cylinder from the air inlet, forming a strong rotating airflow inside the conical separation cylinder. In this process, the solid particles are subjected to a centrifugal force much greater than their gravity and inertia due to their large mass, and are therefore pushed to the inner wall of the conical separation cylinder. They move along the wall with the rotating airflow and are finally discharged from the discharge port at the bottom of the conical separation cylinder. At the same time, the purified gas forms an upward internal vortex in the central area and is discharged from the first connecting pipe at the top.

[0012] Preferably, the purification mechanism includes a purification box, the outer wall of the dust removal box is connected to a second connecting pipe, a plurality of first fixed partitions and second fixed partitions are fixedly installed in the purification box, and the end of the second connecting pipe passes through the purification box;

[0013] The second connecting pipe passes through the first fixed partition and the second fixed partition to the bottom end of the purification box, the top of the purification box is connected to the third connecting pipe, and the top of the purification box is provided with a liquid inlet;

[0014] A plurality of first vent holes are evenly and evenly opened around the top of the first fixed partition, a plurality of second vent holes are evenly and evenly opened in the center of the second fixed partition, and connecting pipes are sequentially arranged on the first fixed partition and the second fixed partition from bottom to top;

[0015] It is used to purify the filtered gas, injecting purification liquid into the purification box through the liquid inlet, and the purified gas enters the purification box through the second connecting pipe, so that the gas contacts the purification liquid, and the gas is discharged from the first vent hole and the second vent hole in sequence. The staggered arrangement of the first vent hole and the second vent hole increases the movement distance of the gas, so that the gas repeatedly contacts the purification liquid, ensuring that the gas is fully purified.

[0016] Preferably, the adsorption mechanism includes an adsorption box, the bottom end of the outer wall of the adsorption box is connected to the end of the third connecting pipe, the adsorption box is filled with activated adsorption carbon, and a plurality of air outlet holes are evenly spaced at the top of the adsorption box;

[0017] It is used to adsorb the purified gas to ensure that the waste gas is fully purified.

[0018] The utility model has the following beneficial effects:

[0019] 1. By setting up a dust removal mechanism, when the filter bag is filtering the gas, the drive motor is started, and the drive motor drives the sector gear to rotate. When the sector gear cooperates with the fixed rack, the fixed rack drives the sliding column to move upward. When the sector gear is disengaged from the fixed rack, the weight of the sliding column and the fixed rack causes the sliding column to move downward. As the sliding column moves up and down, the filter bag shakes, thereby shaking the filter bag and preventing the filter bag from being blocked by low-diameter particles.

[0020] 2. By setting up a purification mechanism, the purification liquid is injected into the purification box through the liquid inlet, and the purified gas enters the purification box through the second connecting pipe, so that the gas contacts the purification liquid. The gas is discharged from the first vent and the second vent in sequence. The staggered setting of the first vent and the second vent increases the movement distance of the gas, so that the gas repeatedly contacts the purification liquid, ensuring that the gas is fully purified.
