The first box 1 is used for being sleeved on the periphery of the ventilation pipeline 2 for discharging the polluted gas, the bottom of the first box 1 is open, and a first cavity 11 communicated with the air outlet of the ventilation pipeline 2 is formed in the first box 1. Specifically, the first box 1 is sleeved on the periphery of the air outlet of the air duct 2, and the top wall of the first box 1 is arranged at intervals with the top of the air outlet of the air duct 2, so that the polluted air discharged through the air outlet of the air duct 2 can be filled into the first cavity 11 and flow out through the bottom opening of the first cavity 11. Wherein, the inner wall of the first box 1 and the periphery of the ventilation pipeline 2 are arranged at intervals to ensure that the gap between the first box 1 and the ventilation pipeline 2 meets the ventilation requirement. The periphery at first box 1 is established to second box 3 cover, and the inside of second box 3 is formed with the second cavity 31 with the uncovered intercommunication of first cavity 11, and the top of second box 3 is equipped with the gas vent with the uncovered of second cavity 31 intercommunication, wherein, the top of second box 3 is uncovered, and the uncovered end at the top of second box 3 can set up the lid, and the gas vent runs through the setting on the lid, adopts split type design mode with second box 3 can be convenient for the washing of second box 3.

Specifically, the bottom of the second casing 3 is connected to the outer periphery of the ventilation duct 2, so that the bottom of the second casing 3 is sealed from the ventilation duct 2, avoiding liquid leakage. The second box 3 is completely sleeved on the periphery of the first box 1, and the inner wall of the second box 3 and the outer wall of the first box 1 are arranged at intervals to ensure that the volume of the second cavity 31 meets the use requirement. At this time, as shown in fig. 2, the first casing 1 is communicated with the outer periphery of the ventilation pipe 2 and the first casing 1 is communicated with the second casing 3 to form an exhaust passage, and the exhaust passage is in a reverse folded shape, so that the length of the exhaust passage is increased to meet the washing requirement of the polluted gas. The structures of the first case 1 and the second case 3 are not limited, and may be rectangular, spherical, or irregular, and only the exhaust passage between the first case 1 and the second case 3 is required to be ensured.
According to the filtering equipment provided by the application, when the filtering equipment is used, liquid is injected towards the second box body 3 through the liquid supply pipeline 4, water seals (water seal exhaust channels) are formed between the first box body 1 and the second box body 3 and between the second box body 3 and the ventilation pipeline 2 by the liquid, so that polluted gas is discharged through the air outlet of the ventilation pipeline 2, impurities are filtered through the water seal layer and then discharged through the air outlet, environmental pollution is avoided, the first box body 1, the second box body 3 and the ventilation pipeline 2 can be washed through liquid replenishment, the phenomenon of blocking of the ventilation pipeline 2 caused by impurity scaling is avoided, meanwhile, the whole process does not need to be manually participated, and the labor cost is reduced.

The polluted gas filtration apparatus further comprises a gas supplementing pipe 5, and a gas outlet of the gas supplementing pipe 5 is used for communicating with the ventilation pipe 2. Wherein the air make-up line 5 may be used to supplement air to ensure pressure balance within the device. The design improves the original unified air inlet and exhaust channel into a mode of separately carrying out air inlet and exhaust so as to meet the breathing function of the ventilation pipeline 2.
The air supply line 5 is provided with a first check valve 51 for allowing air to enter the air line 2. That is, the first check valve 51 is a direction control valve capable of making the air flow in one direction but not in the opposite direction, which is a conventional art, and its specific structure and operation principle are not described too much. In the present application, the first check valve 51 can allow the gas to be transported toward the ventilation pipe 2 through the ventilation pipe 5, thereby preventing the polluted gas in the ventilation pipe 2 from flowing toward the ventilation pipe 5, and avoiding the polluted gas in the ventilation pipe 2 from leaking out and polluting the environment.
The polluted gas filtering apparatus further includes an overflow pipe 6, one end of the overflow pipe 6 is communicated with the second tank 3, the other end of the overflow pipe 6 is communicated with the aeration pipe 2, and one end of the overflow pipe 6 connected with the second tank 3 is located above the aeration pipe 2, so that overflowed liquid can enter the aeration pipe 2 through the overflow pipe 6 or directly overflow into a tank body of a limestone slurry tank described below.
Before the polluted gas filtration apparatus is used, the polluted gas filtration apparatus needs to be supplemented with liquid toward the second tank 3 through the liquid supply pipe 4, and since the second cavity 31 is communicated with the first cavity 11, the liquid will flow toward the first cavity 11 through the second cavity 31 to form a water seal between the first cavity 11 and the second cavity 31, at this time, when the liquid supplied from the liquid supply pipe 4 is more, the liquid will flow toward the air supply pipe 2 through the air outlet of the air supply pipe 2 and then enter the apparatus (slurry tank). When the ventilation pipeline 2 is in a delayed condition in the liquid supplementing process, in order to prevent untimely overflow, redundant liquid can be flowed back into the ventilation pipeline 2 through the overflow pipeline 6 or directly overflowed into a box body of a limestone slurry box described below, so that the liquid is prevented from leaking.
The overflow conduit 6 is provided with a second one-way valve 61 for admitting fluid into the venting conduit 2. The overflow pipe 6 is used for preventing the excessive liquid in the first tank 1 and the second tank 3 from being used, and the second check valve 61 is a directional control valve capable of enabling the fluid to flow along one direction but not to flow reversely, which is a conventional technology, and the specific structure and working principle thereof are not excessively described herein. In the application, the second one-way valve 61 allows fluid to enter the ventilation pipeline 2 from the second box body 3, prevents the polluted gas in the ventilation pipeline 2 from flowing back through the overflow pipeline 6, prevents the polluted gas from entering the second box body 3 from the overflow pipeline 6, and then is discharged through the exhaust port, thus reducing environmental pollution. The overflow pipe 6 is connected with the second tank 3 and the ventilation pipe 2 through an elbow, and of course, in order to reduce the elbow, the overflow pipe 6 may also be arranged in a slurry tank directly inserted into the ventilation pipe 2.
The liquid supply pipe 4 is provided with a stop valve 41 for adjusting the opening degree of the liquid supply pipe 4. The stop valve 41 is a valve for controlling the flow of the medium in the pipeline, which is a conventional technology, and the structure and the working principle of the stop valve are not excessively described herein. In the present application, the stop valve 41 is used to control the opening of the liquid supply pipe 4, so that the liquid supply pipe 4 can supplement liquid to the second tank 3 at a preset flow rate, and overflow of the liquid in the second tank 3 is reduced. When the liquid supply pipe 4 is replenished with liquid, the stop valve 41 may be kept at a fixed opening degree, and the water storage, flushing and replacement of the filter device may be maintained. Wherein, when water is stored, the opening degree of the stop valve 41 is smaller, so that the liquid can be uniformly filled into the first tank 1 and the second tank 3. During flushing, the opening of the stop valve 41 is larger, so that liquid can flush the bending position of the water flow, and scaling is avoided. At the time of replacement, the opening degree of the shutoff valve 41 may be relatively large so that the liquid in the first tank 1 and the second tank 3 can be replaced into the ventilation pipe 2.
As shown in fig. 1 to 3, a protective cover 7 is provided above the second casing 3, and the protective cover 7 can cover the second casing 3 in the vertical direction. Wherein, protection casing 7 can prevent effectively that external impurity or rainwater from entering into in the second box 3 through the gas vent of second box 3, avoids polluting the internal environment of second box 3, simultaneously, can prevent impurity jam gas vent, avoids influencing gaseous discharge. Specifically, the shield 7 may be umbrella-shaped so that the foreign matter or rainwater falling onto the shield 7 can slide down to the outer periphery of the second casing 3 along the shield 7.
In addition, the first casing 1 of the present application is not limited in the manner of being sleeved on the periphery of the air duct 2, for example, a plurality of mounting plates may be disposed on the inner wall of the air duct 2 at intervals along the circumferential direction of the air duct 2, one support column is disposed on top of each mounting plate, and the top end of each support column extends out of the air duct 2, and the extending end of each support column is connected with the top plate of the first casing 1, so as to support the first casing 1 on the periphery of the air duct 2 through the support column, preferably, the support columns are 3, and the included angle between the connecting lines of two adjacent support columns and the central line of the air duct 2 is 120 °, and of course, the included angle between the connecting lines of the two connected support columns and the central line of the air duct 2 is the same. In this design, the installation of the first box 1 does not affect the outflow of the polluted gas, so as to keep ventilation smooth. Alternatively, a plurality of support columns may be provided on the outer periphery of the ventilation duct 2 in the horizontal direction, and the plurality of support columns may be provided at intervals in the circumferential direction of the ventilation duct 2, with the end portions of the support columns being connected to the inner wall of the first casing 1, which is not limitative.
The polluted gas filtering device of the present application may be disposed on the outer periphery of the aeration pipe 2 of the limestone slurry tank, or may be disposed on the outer periphery of other aeration pipes 2 requiring the removal of polluted gas, such as the outer periphery of the aeration pipe 2 of the lime slurry tank. In addition, heat preservation or heat tracing is added outside the second box body 3 and outside the liquid supply pipeline 4 according to the environment temperature condition, so that the liquid is ensured to meet the filtering requirement.

The traditional inverted U-shaped ventilation pipeline 2 is easy to be arranged at the bending position of the ventilation pipeline 2, and the exhausted gas is easy to pollute the environment. After the periphery of the gas outlet of the gas vent pipeline 2 of the limestone slurry tank is provided with a polluted gas filtering device, polluted gas discharged through the gas vent pipeline 2 passes through the water seal layer to filter powder in the polluted gas through the water seal layer, so that the polluted environment is avoided from being discharged, and the second tank 3 can flush the gas vent channel when liquid is supplemented, the scaling of the gas vent pipeline 2 is avoided, the deviation risk of a tank differential pressure liquid level meter is eliminated, the labor operation cost is reduced, and after new liquid is supplemented, the original liquid in the second tank 3 enters the tank, so that the liquid is prevented from being wasted.
The limestone slurry tank adopting the design mode is skillfully improved into a mode that air inlet and air exhaust are separately carried out, and meanwhile, the polluted gas filtering equipment is additionally arranged on the ventilation pipeline 2, so that the breathing function and the air exhaust cleaning function of the ventilation pipeline 2 are simultaneously met. Solves the problem of environmental pollution caused by dust emission at the vent of the limestone slurry tank. The design method not only meets the ventilation function of the box body due to pressure change caused by liquid level change, but also solves the problem of environmental pollution caused by the fact that the discharged gas contains moist air and stone powder.
Further optimally, the tank body is connected with a water supplementing pipeline so as to supplement liquid to the tank body through the water supplementing pipeline, and a liquid inlet of the liquid supplying pipeline 4 is communicated with the water supplementing pipeline. According to the design mode, liquid is supplemented for the box body through the original water supplementing pipeline on one hand, and on the other hand, the water supplementing pipeline is used as a sealing water source, so that the equipment cost is reduced, and the polluted gas filtering equipment of the design mode does not require water quality and water pressure, and water before and after washing is not wasted.
