By energizing the suction pump to operate, the water in the water collection layer inside the circulation tank is sucked, and the water is transported to the inside of the spray pipe through the pipeline. At the same time, the water is evenly sprayed into the inside of the tank body through the nozzles, and the polluted gas and solid particles in the waste gas are absorbed and dissolved by the sprayed water.

[0008] As an optimization of the above technical solution, a plurality of intake pipes are fixedly installed inside the purification tank. The plurality of intake pipes penetrate through the bottom end of the purification tank and extend to the upper side of the spray pipe. One side of the outer wall of the tank body is installed with a water pump through a mounting plate. The output end of the water pump extends into the inside of the tank body through a pipeline.

By opening the control valve, it is convenient to transport the water for purifying the waste gas inside the purification tank to the filtering layer inside the circulation tank. The water collection layer inside the circulation tank is convenient for collecting the filtered water. The water pump is energized to operate to suck the water inside the water collection layer back into the inside of the purification tank through the pipeline.

The adsorbed water flows through the through holes opened in the partition plate to the water collection layer inside the circulation tank. When the adsorption cotton inside the adsorption layer adsorbs too many impurities, the operator opens the sealing cover, separates the sealing cover from the filtering component from the filtering layer, and manually pushes the sliding seat by the operator. The pushed sliding seat drives the slider to slide inside the sliding groove. The sliding slider drives the sliding seat to move parallel to one end of the sliding groove.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0024] Such as Figures 1-7As shown in the figure, the utility model provides a technical solution: an incineration waste gas treatment device, including a base 1. Inside the base 1, a tank body 2 is fixedly installed. At the lower side inside the tank body 2, a spraying mechanism 3 for spraying water is fixedly installed through a mounting plate. The spraying mechanism 3 includes a spray pipe 301. The spray pipe 301 is fixedly installed at the lower side inside the tank body 2 through a mounting plate. At the bottom end of the spray pipe 301, spray heads 302 are equidistantly installed. On one side of the outer wall of the tank body 2, a suction pump 303 is fixedly installed through a mounting plate. The output end of the suction pump 303 is fixedly connected to the input end of the spray pipe 301 through a pipeline. By energizing the suction pump 303 to operate, the water in the water collection layer inside the circulation tank 7 is sucked and circulated, and the water is transported to the inside of the spray pipe 301 through the pipeline. At the same time, the water is evenly sprayed into the inside of the tank body 2 through the spray heads 302. The polluted gas and solid particles in the waste gas are absorbed and dissolved by the sprayed water. Above the spraying mechanism 3 inside the tank body 2, a purification tank 4 for preliminarily purifying the waste gas is fixedly installed. Inside the purification tank 4, multiple air inlet pipes 401 are fixedly installed. The multiple air inlet pipes 401 penetrate through the bottom end of the purification tank 4 and extend to the upper side of the spray pipe 301. On one side of the outer wall of the tank body 2, a water pump 402 is installed through a mounting plate. The output end of the water pump 402 extends into the inside of the tank body 2 through a pipeline. The output end of the pipeline is fixedly connected to a water outlet pipe arranged above the purification tank 4. On one side of the purification tank 4 close to the water outlet pipe, a control valve 403 is installed through a pipeline. The treated gas then enters the inside of the purification tank 4 through the multiple air inlet pipes 401, and the gas is preliminarily purified by the water inside the purification tank 4. Above the purification tank 4 inside the tank body 2, a purification mesh plate 5 for secondary purification is fixedly installed. At the upper and lower ends inside the purification mesh plate 5, mesh holes for facilitating the flow of gas are opened. The inside of the purification mesh plate 5 is filled with activated carbon. The gas that has been preliminarily purified flows upward into the inside of the purification mesh plate 5, and the activated carbon inside the purification mesh plate 5 adsorbs and processes the preliminary gas. Above the purification mesh plate 5 inside the tank body 2, a fan 6 is fixedly installed through a mounting frame. Outside the base 1 close to the tank body 2, a circulation tank 7 is installed through a support seat. At the top end of the circulation tank 7, a sealing cover 701 is snap-fitted and installed. Inside the circulation tank 7, a partition plate 702 for separating the space is fixedly installed. The upper side of the partition plate 702 is a filter layer, and the lower side of the partition plate 702 is a water collection layer. On one side inside the partition plate 702, a through hole is opened. One side of the filter layer is fixedly connected to the output ends of the spray pipe 301 and the control valve 403 through a pipeline. One side of the water collection layer is fixedly connected to the input end of the water pump 402 through a pipeline. On one side of the outer wall of the circulation tank 7, a water inlet valve is fixedly installed. By opening the control valve 403, it is convenient for the water for purifying the waste gas inside the purification tank 4 to be transported to the filter layer inside the circulation tank 7. The water collection layer inside the circulation tank 7 is convenient for collecting the filtered water. The water pump 402 is energized to operate to suck the water inside the water collection layer back into the inside of the purification tank 4 through the pipeline, and at the same time, the suction pump 303 sucks the water inside the water collection layer into the inside of the spray pipe 301.It is convenient for the water inside the water collection layer to be recycled. Connecting an external water source through the water inlet valve facilitates the replenishment of the water inside the water collection layer and the recycling of the water inside the water collection layer. A filtering component 8 for filtering water is fixedly installed at the bottom end of the sealing cover 701, and the filtering component 8 is arranged on the upper side inside the circulation tank 7.

[0025] It should be noted that limiting grooves are opened on both sides of the sliding groove 805, and limiting blocks (not shown in the figure) are fixedly installed on both sides of the sliding block 806. By engaging the limiting blocks into the limiting grooves, it is convenient for the sliding block 806 not to fall out of the inside of the sliding groove 805 when sliding inside the sliding groove 805.

[0026] As an implementation method in this embodiment, as Figure 2 、 Figure 5 、 Figure 6 and Figure 7 shown, the filtering component 8 is composed of a first filter net 801, an adsorption layer 802 and a second filter net 803. An adsorption layer 802 is fixedly installed on one side of the first filter net 801. The inside of the adsorption layer 802 is filled with adsorption cotton. A second filter net 803 is fixedly installed on the side of the adsorption layer 802 away from the first filter net 801. Sliding grooves 805 are opened inside both sides of the first filter net 801, the adsorption layer 802 and the second filter net 803. Sliding blocks 806 are installed in the sliding grooves 805 through limiting blocks and limiting grooves. A sliding seat 804 is fixedly installed at the bottom end of the sliding block 806, and the sliding seat 804 is slidably installed at the bottom ends of the first filter net 801, the adsorption layer 802 and the second filter net 803. The impurities in the water are filtered by the first filter net 801 and the second filter net 803, and at the same time, the soot contained in the water is adsorbed by the adsorption layer 802. The adsorbed water flows through the through holes opened in the partition plate 702 to the water collection layer inside the circulation tank 7. When the adsorption cotton inside the adsorption layer 802 adsorbs too many impurities, the operator opens the sealing cover 701, disengages the sealing cover 701 and the filtering component 8 from the filter layer, and manually pushes the sliding seat 804 by the operator. The sliding sliding seat 804 drives the sliding block 806 to slide inside the sliding groove 805. The sliding sliding block 806 drives the sliding seat 804 to move parallel to one end of the sliding groove 805. The sliding seat 804 at one end of the sliding groove 805 disengages from the bottom of the adsorption layer 802, thereby opening the replacement channel at the bottom of the adsorption layer 802, facilitating the operator to replace the adsorption cotton inside the adsorption layer 802.

[0027] As an implementation method in this embodiment, as Figure 1As shown in the figure, an air inlet 201 is provided on the outer wall of the tank body 2 on the side far from the circulation tank 7. Both sides of the bottom end of the tank body 2 are penetrated and installed with a water outlet 202. The top end of the tank body 2 is fixedly installed with an exhaust pipe 203. A controller 9 is fixedly installed on the top end of the base 1 near the outer wall of the tank body 2. The incineration device is externally connected through the air inlet 201, so that the waste gas incinerated by the incineration device flows into the tank body 2 through the air inlet 201. The sewage collection mechanism is externally connected through the water outlet 202. At the same time, the sprayed sewage is discharged into the collection mechanism through the water outlet 202. The purified gas is discharged through the exhaust pipe 203. The controller 9 is electrically connected to the suction pump 303, the water pump 402, the control valve 403, the fan 6 and the water inlet valve through wires, which is convenient for the operator to control the power-on operation of the device through the controller 9.

[0028] Working principle: The incineration device is externally connected through the air inlet 201, so that the waste gas incinerated by the incineration device flows into the tank body 2 through the air inlet 201. When the incinerated waste gas enters the tank body 2, the suction pump 303 is powered on to suck the water in the water collection layer of the circulation tank 7 and transport the water to the inside of the spray pipe 301 through the pipeline. At the same time, the water is evenly sprayed into the tank body 2 through the spray head 302. The polluted gas and solid particles in the waste gas are absorbed and dissolved by the sprayed water. The sewage collection mechanism is externally connected through the water outlet 202. At the same time, the sprayed sewage is discharged into the collection mechanism through the water outlet 202. The treated gas then enters the purification tank 4 through multiple intake pipes 401 and is preliminarily purified by the water in the purification tank 4. The gas after preliminary purification flows upward into the purification mesh plate 5, and the activated carbon in the purification mesh plate 5 adsorbs and processes the preliminary gas. At the same time, the fan 6 is powered on to generate wind power, and the wind power discharges the purified gas through the exhaust pipe 203.

[0029] By opening the control valve 403, the water for purifying the waste gas in the purification tank 4 is transported to the filter layer inside the circulation tank 7. The impurities in the water are filtered by the first filter screen 801 and the second filter screen 803. At the same time, the soot contained in the water is adsorbed by the adsorption layer 802. The adsorbed water flows through the through holes opened in the partition plate 702 into the water collection layer inside the circulation tank 7, and the water pump 402 is powered on to suck the water in the water collection layer back into the purification tank 4 through the pipeline. At the same time, the suction pump 303 sucks the water in the water collection layer into the spray pipe 301, which is convenient for the water in the water collection layer to be recycled, realizing the function of reusing the water replaced after purifying the waste gas.

[0030] When the impurity adsorbed by the adsorption cotton inside the adsorption layer 802 is excessive, the operator opens the sealing cover 701, disengages the sealing cover 701 from the filter assembly 8 from the filter layer, and the operator manually pushes the sliding seat 804. The pushed sliding seat 804 drives the slider 806 to slide inside the chute 805. The sliding slider 806 drives the sliding seat 804 to move parallel to one end of the chute 805. The sliding seat 804 at one end of the chute 805 disengages from the bottom of the adsorption layer 802, thereby opening the replacement channel at the bottom of the adsorption layer 802, facilitating the operator to replace the adsorption cotton inside the adsorption layer 802, and avoiding excessive impurities adsorbed inside the adsorption cotton from affecting the adsorption effect of the adsorption cotton.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
