Therefore, before producing aluminum plate, a smelting furnace is required to produce and process the aluminum ingots for further processing. In the process of using the smelting furnace, it is inevitable that a certain amount of high-temperature harmful flue gas will be generated. Direct emission will cause pollution to the atmospheric environment. Therefore, a flue gas treatment and purification device is needed to treat this part of the flue gas.

[0003] The prior art discloses a flue gas treatment device for an environmentally friendly smelting furnace for aluminum plate production with a publication number of CN218924188U, comprising a treatment box, a stirring assembly is provided at the bottom of the inner cavity of the treatment box, a partition is fixedly connected to both sides of the inner cavity of the treatment box, an outlet valve is provided in the inner cavity of the partition, and a moisture absorption plate is fixedly connected to both sides of the inner cavity of the treatment box. The utility model cools the exhaust gas entering the treatment box through an atomizing pipe, and at the same time, the setting of the stirring assembly can stir the inside, increase the contact area between the flue gas and the spray, and realize rapid cooling treatment of the flue gas. At the same time, the water mist can treat the impurities dissolved in water in the exhaust gas, and the wastewater is pumped into the circulation box through a circulation pipe and a circulation pump, and is processed by a filter net for later reuse. Then the outlet valve is started to discharge the cooled exhaust gas upward, first through the moisture absorption plate for dehumidification, then through the filter plate for purification, and finally discharged.

[0004] During use, the above-mentioned utility model utilizes a filter to filter out impurities in the wastewater, thereby realizing the recycling of the cooling wastewater.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides an environmentally friendly smelting furnace fume treatment device for aluminum plate production, which has the following beneficial effects:

[0017] (1) The utility model is provided with a treatment box, a circulation box and a scraper. When in use, the flue gas generated by the environmentally friendly smelting furnace for aluminum plate production is introduced into the inner cavity of the treatment box through the air inlet pipe. At this time, the worker starts the pressure pump installed on the branch pipe to pump the cooling water in the circulation box into the connecting pipe through the branch pipe, and then the cooling water is evenly distributed to the inner cavities of several atomizing tubes installed in the inner cavity of the treatment box through the connecting pipe. Several atomizing nozzles are installed on the bottom surface of the atomizing tube, so that the cooling water can be atomized and sprayed out, so that it can fully contact with the flue gas, cool down and reduce dust on the flue gas, and preliminarily absorb soluble harmful substances in the flue gas. At the same time, the user starts the servo motor installed on one side of the treatment box to drive the transmission shaft to rotate, and uses several stirring rods evenly installed on the transmission shaft to accelerate the contact efficiency and contact area between the flue gas and the atomized water, thereby further improving the flue gas treatment effect. The wastewater generated by dust reduction and cooling of the flue gas falls to the bottom of the treatment box. At this time, the circulation pump installed on the circulation pipe is started to pump this part of the wastewater back into the circulation pipe. In the inner cavity of the ring box, a filter is fixedly installed in the inner cavity of the circulation box. Waste water needs to be filtered through the filter before it can enter the branch pipe for recycling again. The filter can filter out impurity particles in the waste water, and the filtered impurity particles will adhere to and clog the bottom of the filter. Because the transmission shaft is located in the inner cavity of the circulation box, a mounting frame is fixedly installed, and scrapers are symmetrically fixedly installed at both ends of the mounting frame, and the scrapers are in contact with the bottom of the filter. Therefore, when the transmission shaft drives the mounting frame to rotate together with the scraper, the rotating scraper can be used to scrape off impurities attached to and clogged on the bottom of the filter. The cleaned impurities fall into the sewage collecting hopper fixedly installed on the bottom of the circulation box for sedimentation. When they accumulate to a certain extent, the user opens the sewage pipe to discharge the collected impurity sludge, thereby enabling an environmentally friendly smelting furnace flue gas treatment device for aluminum plate production to automatically complete the anti-blocking cleaning of the filter without adding additional power cleaning mechanisms, thereby ensuring the smooth recycling of wastewater, saving water resources, and being more practical.

[0018] (2) The utility model is provided with a first partition, a second partition, a third partition and a sealing cover. The first partition is fixedly installed in the inner cavity of the processing box, and a plurality of one-way valves are evenly fixedly installed on the first partition. The flue gas that is fully in contact with the cooling water can enter the enclosed space formed by the first partition, the second partition and the third partition through the one-way valve. The two third partitions are fixedly installed with connecting pipes in the center of the bottom surface, and the connecting pipes are installed with electromagnetic valves. At this time, the worker opens the electromagnetic valve on one side to allow the cooled flue gas to enter the enclosed space formed by the second partition and the third partition on one side. The first placement seat fixedly installed in the space is installed with a moisture absorption plate, which can dehumidify and dry the water vapor in the flue gas. The second placement seat is fixedly installed in the space, and the desulfurization catalyst layer, an oxygen gas layer and the like are placed on the second placement seat in sequence. The carbon monoxide catalyst layer and the activated carbon adsorption layer can absorb and treat the toxic and harmful components in the flue gas, and finally the purified flue gas is discharged through the exhaust pipe installed on the sealing cover. When the desiccant plate, desulfurization catalyst layer, carbon monoxide catalyst layer and activated carbon adsorption layer need to be replaced, the user can close the solenoid valve on the connecting pipe on this side and open the solenoid valve on the connecting pipe on the other side, and then open the sealing cover installed on the top surface of the treatment box through the hinge to take out and replace the desiccant plate, desulfurization catalyst layer, carbon monoxide catalyst layer and activated carbon adsorption layer, so that the fume treatment device of an environmentally friendly smelting furnace for aluminum plate production can quickly replace the desiccant plate, desulfurization catalyst layer, carbon monoxide catalyst layer and activated carbon adsorption layer without stopping the machine, which is simple and convenient to operate and improves its flue gas treatment efficiency.
