DETAILED DESCRIPTION

[0024] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0025] Reference Figure 1-Figure 4 , an environmentally friendly waste gas treatment equipment includes a treatment box 1, an air inlet pipe 2 is fixedly connected to the end of the treatment box 1, and the end of the air inlet pipe 2 is fixedly connected to the inner wall of the treatment box 1. A plurality of air outlet pipes 10 are evenly distributed on the outer wall of one end of the air inlet pipe 2 located in the treatment box 1. The air outlet pipe 10 is vertically downwardly arranged away from the end of the air inlet pipe 2. The waste gas is introduced into the treatment box 1 from the air inlet pipe 2. The waste gas entering the air inlet pipe 2 flows to the end of the air outlet pipe 10 and flows out, first flowing downward and then flowing upward to extend the flow distance. At the same time, the end of the air outlet pipe 10 is arranged downward, and the spray liquid will not enter the air outlet pipe 10, so that the waste gas can be discharged smoothly.

[0026] The end of the air inlet pipe 2 is fixedly sleeved with a heat-insulating sleeve 3, and a plurality of heat-conducting rods 5 are fixedly inserted together with the heat-insulating sleeve 3 and the air inlet pipe 2, and an evaporation box 4 is fixedly sleeved on the upper ends of the plurality of heat-conducting rods 5, and a mounting plate 7 is fixedly embedded on the outer wall of the treatment box 1, and a plurality of steam ports are opened at one end of the mounting plate 7 located in the treatment box 1, and a connecting pipe 6 is fixedly connected between the outer wall of the mounting plate 7 and the outer wall of the evaporation box 4, and a filter element layer 26 is provided at the inner bottom of the treatment box 1, and a spray plate 8 located on the upper side of the filter element layer 26 is fixed in the treatment box 1, and a spray liquid pump is fixed on the outer wall of the treatment box 1, and the input end of the spray liquid pump is connected to the spray plate 8, and an exhaust pipe 9 is fixedly connected to the upper side wall of the treatment box 1, and the spray liquid pump pumps external washing liquid into the spray plate 8 The washing liquid is then sprayed from the spray plate 8 into the treatment box 1 to contact the exhaust gas for treatment. The washing liquid can be acid, alkali, water and other common liquids for exhaust gas treatment. After the washing liquid treats the exhaust gas, it falls on the filter element layer 26 to filter the washing liquid. The washing liquid flows to the bottom of the treatment box 1 and can be pumped out for reciprocating use. The heat in the exhaust gas is conducted to the evaporation box 4 through the heat conducting rod 5 to heat the water in the evaporation box 4 to generate steam, which then flows into the treatment box 1 through the connecting pipe 6. In order to avoid excess particles flying up when the washing liquid contacts the exhaust gas and does not contact the washing liquid, steam is pumped in to contact the particles in the exhaust gas to increase their weight and fall on the filter element layer 26.

[0027] The upper side wall of the evaporation box 4 is fixedly connected with a connecting pipe, the upper end of the connecting pipe is fixedly connected with a water supply tank 11, a solenoid valve 13 is installed on the connecting pipe, a movable rod 14 is slidably inserted on the evaporation box 4, the lower end of the movable rod 14 is fixedly connected with a float, the upper end of the movable rod 14 is fixedly connected with a trigger plate 15, the upper side wall of the evaporation box 4 is fixed with a switch 12 located on the lower side of the trigger plate 15, the switch 12 is connected to the solenoid valve 13 through a wire, the switch 12 adopts a delayed reset switch, a slide plate that fits the inner wall of the water supply tank 11 is slidably provided in the water supply tank 11, an adjusting rod 16 is fixedly connected to the upper side wall of the slide plate, and the upper end of the adjusting rod 16 penetrates the exhaust pipe 9 and is set , a plurality of adsorption ports 17 are evenly arranged from top to bottom on the adjusting rod 16, and filter screens are fixedly connected to the inner walls at both ends of the adsorption ports 17, and activated carbon is filled in the adsorption ports 17. When the water in the evaporation box 4 evaporates, the height of the float ball decreases, and the trigger plate 15 contacts the switch 12, giving a signal to the solenoid valve 13 to open it, and the water in the water replenishment tank 11 flows out to the evaporation box 4 to replenish the water. At this time, the float ball floats up again, and the trigger plate 15 no longer presses the switch 12. The switch 12 is a delayed reset switch, and a specific time can be set. After a certain period of time, the switch 12 is disconnected, the solenoid valve 13 is closed, and the water in the evaporation box 4 continues to evaporate;

[0028] The exhaust gas in the treatment box 1 is discharged into the exhaust pipe 9 after being treated. While flowing out, it passes through the adsorption port 17, and the odor or residual harmful substances are adsorbed and discharged by the activated carbon. The activated carbon will be fully adsorbed after a certain period of time. As the water in the water supply tank 11 is discharged into the evaporation box 4, the slide plate in the water supply tank 11 slides downward, and the height of the adjustment rod 16 and the adsorption port 17 are synchronously reduced, so that the activated carbon connected to the exhaust pipe 9 is replaced.

[0029] The outer wall of the processing box 1 is fixedly connected to the working box 18, and the outer wall of the working box 18 is fixedly embedded with a motor 19. The driving end of the motor 19 is fixedly connected to a rotating shaft. The outer wall of the rotating shaft is fixedly sleeved with a gear 20. The gear 20 is an incomplete gear. The end of the rotating shaft extends into the processing box 1 and is fixedly connected with a scraper 27. The upper side wall of the filter layer 26 is provided with an arc surface. The end of the scraper 27 is provided with an opening. A filter screen 28 is slidably inserted in the opening. The end of the filter screen 28 is fixed between the inner wall of the opening. A telescopic spring is connected, and the end of the filter screen 28 moves along the arc surface. The motor 19 drives the gear 1 20 to rotate. When the gear 1 20 is engaged with the tooth plate 22, the tooth plate 22 is driven to move to the left. When the gear 1 20 rotates to engage with the gear 2 21, the gear 2 21 drives the tooth plate 22 to move to the right. Through the above work, the tooth plate 22 and the stirring plate are moved back and forth, driving the water in the evaporation box 4 to shake. Under the shaking action, the water continuously impacts the heat conducting rod 5, thereby accelerating the evaporation of the water.

[0030] A gear 21 meshing with the gear 1 20 is installed in the working box 18, and the gear 21 is a complete gear. A tamping rod 24 is slidably inserted into the outer wall of the evaporation box 4, and the end of the tamping rod 24 located in the evaporation box 4 is fixedly connected to a tamping plate, and the end of the tamping rod 24 located outside the evaporation box 4 is fixedly connected to a connecting plate 23, and the end of the connecting plate 23 extends through and extends into the working box 18 and is fixedly connected to a toothed plate 22 meshing with the gear 1 20 and the gear 2 21, a magnet block 1 29 is fixedly embedded on the filter layer 26, and a magnet block 2 that is set to repel the magnet block 1 29 is fixedly embedded on the filter screen 28, and a notch is provided at the end of the filter layer 26, and a collection box 25 whose end is in contact with the upper side wall of the notch is inserted on the outer wall of the processing box 1, and a telescopic rod 30 is fixedly connected to the inner wall of the processing box 1, and the end of the telescopic rod 30 is fixed A sealing plate 31 is connected to the end of the collection box 25 for sealing. The gear 1 20 and the gear 2 21 are intermittently meshed to realize the reciprocating forward and reverse rotation of the gear 2 21, driving the filter screen 28 to move along the surface of the filter core layer 26. When the filter screen 28 moves to the magnet block 1 29, under the action of the magnetic repulsion between the magnet block 1 29 and the magnet block 2, the filter screen 28 moves toward the inside of the opening, so that the impurities on the left side of the filter core layer 26 can slide to the right. When the scraper 27 moves to the right, the filter screen 28 can be extended from the opening, so that the impurities are always located on the right side. When the impurities are subsequently cleaned, the driving end of the telescopic rod 30 is retracted to open the end of the collection box 25. When the scraper 27 moves to the right, the filter screen 28 can push the impurities to the collection box 25, slide down into the collection box 25 for collection, and achieve concentration, which is convenient for subsequent processing.
