[0002] At present, the emission of smelting industrial waste gas has become one of the main sources of environmental pollution. The smelting industrial waste gas contains a variety of harmful substances, such as particulate matter, sulfur dioxide, and nitrogen oxides, which pose a serious threat to the atmospheric environment, human health, and the ecosystem. Therefore, effective treatment of smelting industrial waste gas is an inevitable requirement for protecting the environment and achieving sustainable development.

[0003] After searching, the prior art authorization announcement number is CN 114042372 B, which is an environmentally friendly industrial metal smelting waste gas treatment device, including an air inlet, a box, a spray mechanism, a neutralization mechanism, a wastewater treatment mechanism, an adsorption mechanism, and an air outlet; an air inlet is provided at one end of the box; a spray mechanism is provided on one side of the air inlet; a neutralization mechanism is provided on one side of the spray mechanism; a wastewater treatment mechanism is provided on one side of the neutralization mechanism; an adsorption mechanism is provided on one side of the neutralization mechanism; an air outlet is provided at one end of the adsorption mechanism; the spray mechanism includes a water pump I, a spray pipe, a gas distribution hood, a riser plate, a rotor, a rotating shaft, a water pump, a water pump II, and a water inlet pipe; a water pump I is provided at one end of the box; one end of the water pump I is connected to the spray pipe, and the other end is connected to the water inlet pipe. This device performs a spray water bath under the premise that the exhaust gas is only sprayed. The tiny particles entrained in the rising gas of the water bath cannot be completely removed during the spray water bath treatment process, and the large particles in the exhaust gas will cause a large amount of solid waste precipitation in the water bath process, requiring the subsequent water bath wastewater to be treated again.

[0004] After searching, the prior art authorization publication number is CN 112354310 A, which is a multi-stage purification system for industrial waste gas.

[0005] It includes an air inlet, an electrostatic precipitator chamber, a spray chamber, a spoiler mechanism, a UV light oxidation chamber, an exhaust mechanism, a ventilation pipe, and a box. An air inlet is provided on one side of the box, and an exhaust mechanism is provided on the other side.

One end of the ventilation pipe is connected to the electrostatic precipitator chamber and is located in the middle and lower part of the anode plate, and the other end is connected to the spray chamber and is located in the middle and lower part of the spray chamber. The electrostatic precipitator plate of the device is parallel to the inside of the box, and the direction of the gas flow cannot be changed. The electrostatic precipitator adsorption effect is not good for the central gas source far away from the horizontal flow section of the electrostatic precipitator plate. The vibration motor is directly set inside the device without any buffering, which makes the vibration dust removal effect poor, and the resonance of the vibration output will also cause the device as a whole to vibrate unnecessarily, increasing the mechanical fatigue of the fixed connection of the entire device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) Smelting industrial waste gas enters the cooling pipe through the cold zone mechanism from the air inlet. The cooling water is filled inside the cooling box through pump II to cool the smelting industrial waste gas entering the cooling pipe. When the smelting industrial waste gas passes through the filter plate I in the cooling pipe, the large particles of metal and impurities in the smelting industrial waste gas are filtered on the filter plate I. The motor I controls the reciprocating movement of the filter plate I along the direction of the screw through the screw I, and the rotation of the brush plate. When the filter plate I moves to the brush plate, the brush plate brushes the filter plate I. At the same time, the nozzle above the brush plate sprays clean water through pump I to clean the brush plate and filter plate I. The cleaned sewage and the filtered metal residues, impurities and other substances are discharged through the sewage pipe below the brush plate;

[0019] 2) The fan of the airflow control mechanism can control the speed of gas flow according to demand. Motor II controls the rotation of the transmission gear plate through gear I. The transmission gear plate rotates the triangular baffle at a certain angle through its own groove. The triangular baffles rotate with each other to expand or shrink the hexagonal hole in the middle of the triangular baffle, so that the gas intake can be controlled according to demand;

[0020] 3) The gas is diverted through the diversion pipe and enters the electrostatic precipitator box uniformly from bottom to top. The tiny particles in the gas are charged through the longitudinal electrodes. The gas containing charged particles is directed to the adsorption plate I through the blades of the shutter I, so that the charged particles in the gas are adsorbed on the adsorption plate I. The gas reaches the shutter II through the opening at the rear end of the adsorption plate I. The shutter II directs the gas to the adsorption plate II again. The transverse electrodes provided between the multiple groups of adsorption plates II charge the particles in the gas again, and then the dust and particles in the gas are removed through the adsorption plate III. The multiple shutters control the degree of opening and closing of the blades according to demand through the electric push rod. The motor IV and the motor V can control the opening and closing and angle of the shutter I by controlling the longitudinal and transverse movement of the connecting plate. By controlling the opening and closing of the shutter blades and the opening and closing and angle of the shutter as a whole, the flow direction of the incoming gas is controlled, and the flow direction of the central gas source is further changed, so that the gas entering the dust removal mechanism from different directions can better contact the electrostatic precipitator plate, and efficient adsorption dust removal can be performed;

[0021] 4) The motor III of the vibration mechanism controls the rotation of the side shaft, and controls the rotation of the vibration main shaft through the meshing of a group of bevel gears. The transmission rod set on the side shaft and the vibration main shaft rotates, and the transmission rod drives the pendulum to rotate. The two sets of pendulums can vibrate the dust collecting frame from both longitudinal and transverse directions. The top of the dust collecting frame is supported by a support plate and a positioning plate, and positioning springs are arranged around it. The two ends of the dust collecting frame are connected to the electrostatic precipitator box body with rubber sleeves, so that the dust collecting frame can move inside the electrostatic precipitator box body, which not only improves the effect of vibration dust removal, but also enables the dust collecting frame to reset itself after each vibration, and can also keep the impact generated by the vibration mechanism on the dust collecting frame, reducing the overall resonance of the equipment. The motor VI controls the brush plate to clean the dust on the surface of the adsorption plate II, and the dust that falls off the adsorption plate after vibration and cleaning is discharged from the sewage outlet;

[0022] 5) Water inlet and outlet are respectively arranged on both sides of the bottom of the water treatment box. Alkaline water is provided in the water treatment box, and the sulfide in the exhaust gas of the electrostatic precipitator is neutralized by alkaline water. Two sets of filter plate baffles are also arranged on both sides of the water treatment box. The exhaust gas after the electrostatic precipitator enters the water filtration mechanism for water bath neutralization. The filter mechanism filters the overflowing salt mist particles after neutralization, and finally eliminates the salt mist particles by spraying clean water through the rotating spray mechanism. The motor IX of the water filtration mechanism controls the lifting and lowering of the lifting filter plate through the screw V. When the lifting filter plate rises to the fixed plate position, the motor X controls the scraper to scrape the impurities on the lifting filter plate to the outside of the side baffle. The gas passes through the filter mechanism after being neutralized in the water bath. When When filter plate II loses its filtering capacity after long-term use, a new filter plate is placed in one end of the filter plate rack outside the box, and motor VIII is started to move the filter plate rack to the other end. The new filter plate enters the water treatment box body, and the used filter plate is brought out of the water treatment box body. The filter plate baffles on both sides of the water treatment box body are used to limit the position, so that the filter plate can be replaced during the use of the device; the motor VII of the rotary spray mechanism controls the rotation of gear III through the main shaft, gear III engages with gear II, and the two sets of gears II engage with each other, driving the rotary spray pipe in gear II to rotate. The rotary spray does not produce dead angles during spraying, thereby improving the efficiency and quality of spraying. Finally, the completely treated gas is discharged through the outlet.

The motor I 105 controls the filter plate I 114 to reciprocate along the direction of the screw through the screw I 111, and the rotation of the brush plate 113. When the filter plate I 114 moves to the brush plate 113, the brush plate 113 brushes the filter plate I 114, and the brush plate 113 brushes the filter plate I 114.
