Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a multi-stage purification device for controlling and treating industrial harmful waste gas. Background Art

[0002] Waste gas is a derivative of air pollution that is often mentioned nowadays. Today's production enterprises and some chemical industries will inevitably produce polluting harmful gases during production. These gases are directly discharged into the atmosphere, causing serious pollution to the atmosphere and seriously affecting the surrounding air environment.

[0003] In order to ensure that the current enterprise's waste gas emissions are qualified, a purification device will be installed on the emission device to purify the discharged waste gas and avoid the negative impact caused by the direct discharge of waste gas into the air.

[0004] In the related art, reference may be made to Chinese patent publication number CN210934316U, which specifically discloses a multi-stage purification device for controlling and treating industrial hazardous waste gases. When in use, this multi-stage purification device for controlling and treating industrial hazardous waste gases uses a filtering structure to initially filter the waste gases. A spraying structure is provided to further spray and purify the filtered air, achieving a better purification effect. A detachable filter plate facilitates cleaning and replacement. A ramp plate is provided to concentrate the sprayed water and discharge it through an outlet pipe. Multiple nozzles ensure a more uniform spraying and a better purification effect.

[0005] The applicant discovered that there were deficiencies in the use of the above-mentioned multi-stage purification device for controlling and treating industrial hazardous waste gas: although a detachable filter plate was provided for preliminary filtering of the waste gas, the filter plate did not have a structure for continuously filtering the waste gas. As a result, when the filter plate was replaced, the waste gas needed to be stopped from being transported before the filter plate in the comparative document could be replaced. Otherwise, the waste gas that continued to be transported could not be filtered by the filter plate, affecting the purification effect of the waste gas, and the waste gas would be discharged in large quantities through the replacement port, causing pollution.

[0006] In view of this, the present technical solution proposes a multi-stage purification device for controlling and treating industrial harmful waste gas, so as to better solve the above-mentioned problems. Utility Model Content

[0007] The technical solution adopted by the utility model is as follows: a multi-stage purification device for controlling and treating industrial harmful waste gas, comprising a filter cover, the right side of the filter cover is connected to a blower through an air supply pipe, and the left side of the filter cover is connected to a spray mechanism through a transfer pipe;

[0008] A right mounting port and a left mounting port are provided on the upper interior of the filter cover, and a right purification mechanism is plugged into the right mounting port, and a left purification mechanism is plugged into the left mounting port. The left purification mechanism includes a base plugged into the right mounting port and the left mounting port, and a sealing baffle is fixed to the bottom of the base for sealing the right and left mounting ports. A right positioning frame and a left positioning frame are hinged on the top of the base, and a filter plate is clamped inside the right positioning frame and the left positioning frame.

[0009] In a preferred embodiment, the spray mechanism includes a spray box connected to the left end of the transfer tube, a water outlet pipe is connected to the bottom of the spray box, and a discharge pipe is connected to the left side of the spray box, a water storage pipe is provided above the interior of the spray box, and a nozzle is connected to the bottom of the water storage pipe, a water tank is fixed above the spray box, and a water pump is connected to the right side of the water tank, and the water pump is connected to the water storage pipe through a pipeline.

[0010] In a preferred embodiment, the nozzles are linearly distributed below the water storage pipe, and a water inlet is connected to the top of the water tank.

[0011] In a preferred embodiment, an inspection port is provided in front of the filter cover, and a sealing cover is hinged inside the inspection port for sealing the inspection port. The filter cover and the right side of the filter cover can be locked by a lock.

[0012] In a preferred embodiment, the right purification mechanism and the left purification mechanism have the same specifications, and the left purification mechanism is located on the left side of the right purification mechanism.

[0013] In a preferred embodiment, the right positioning frame and the left positioning frame are provided with clamping grooves for limiting the filter plate, and the filter plate is clamped and positioned in the clamping grooves by the right positioning frame and the left positioning frame.

[0014] In a preferred embodiment, magnets are provided at relative positions around the inside of the right positioning frame and the left positioning frame, and the magnets are attracted to each other, and handles are fixed at symmetrical positions above the right positioning frame and the left positioning frame.

[0015] In a preferred embodiment, threaded holes adapted to positioning bolts are provided on both upper sides of the interior of the filter cover and the interior of the base, and the positioning bolts are threadedly connected to the left threaded holes to position the base.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: it is easier to interchange the filter plates inside the right purification mechanism and the left purification mechanism, it is less likely to affect the continuous filtering and cleaning operation of the exhaust gas, and the work efficiency is increased.

[0017] 1. In the utility model, the exhaust gas can be transported to the interior of the filter cover through the air supply pipe by the fan for preliminary filtering treatment. The treated exhaust gas enters the interior of the spray box through the transfer pipe for spray treatment. The treated gas is discharged through the discharge pipe, and the waste liquid can be discharged through the water outlet pipe.

[0018] 2. In the present invention, when the filter plate needs to be replaced, first install the filter plate inside the left purification mechanism, and then remove the positioning bolts from the filter cover and the base. At this time, the left purification mechanism can be inserted into the left mounting port as a whole, and then the right purification mechanism can be pulled upward from the inside of the right mounting port to expose the filter plate inside the right purification mechanism to the upper outside of the filter cover. At the same time, the sealing baffle can seal the opening of the right mounting port. At this time, the positioning bolts are threadedly connected to the filter cover and the base inside the right purification mechanism to position the right purification mechanism as a whole. Then the right positioning frame and the left positioning frame inside the right purification mechanism are flipped over to replace the filter plate. The above installation method can replace the filter plates inside the right purification mechanism and the left purification mechanism in turn without affecting the continuous purification treatment of the exhaust gas.
