[0026] This example proposes an industrial waste gas filtration and treatment device, as shown in the attached Figure 2 And attached Figure 3 As shown, a frame is provided, and a water storage tank assembly 7 is provided on the frame, wherein a PVC upper cover 16 is provided above the liquid storage tank, a sealing strip 31 is provided between the upper cover 16 and the box body 21, a vacuum port is provided at a rearward position of the upper cover 16, an exhaust gas inlet is provided at a middle position of the upper cover 16, a water inlet 25 and a drug adding port 19 are provided at a frontward position of the upper cover 16, a liquid discharge port is provided at the bottom in front of the liquid storage tank, a high-pressure fan 6 is provided on the right side of the liquid storage tank, an electric control box is provided on the upper right side of the entire device, a water receiving tray 9 is provided directly below the liquid storage tank and the high-pressure fan, a water receiving box 12 is provided directly below the water receiving tray 9, and a bottom water receiving tray 13 is provided directly below the water receiving box;

[0027] In this example, the single-chip controller receives the signals of the switch and the sensor to automatically control the solenoid valve, the high-pressure fan, and the water inlet, so as to achieve the effect of automatic water replenishment, and to realize the exhaust gas being pumped to the bottom of the liquid storage tank, and a large number of small bubbles are formed through the aeration pipe, so that the condensed crystalline substances formed by the exhaust gas cooling by water can fully contact and react with the alkaline liquid in the liquid storage tank, and generate salts that dissolve in water, thereby eliminating the condensed crystalline substances;

[0028] Specifically, the box body 21 in the liquid storage box assembly 7 is made of stainless steel, corrosion-resistant, and has a rectangular structure with a support beam in the middle to ensure that the vacuum does not deform; the upper cover 16 is made of transparent PVC material, corrosion-resistant, and convenient for observing the state inside the box. The air inlet 24 and the air outlet 26 are both made of PVC material spiral snap-on interface with a sealing ring, which is corrosion-resistant and easy to disassemble. An operating indicator light 4 is provided, so that the working status of the device can be clearly seen;

[0029] A corresponding lower limit liquid level sensor 18 is provided to monitor the lower limit liquid level value in the liquid storage tank. When this liquid level is reached, the controller controls the water replenishment mechanism to automatically add water, and the yellow indicator light flashes. An upper limit liquid level sensor 17 is also provided. When this liquid level is reached, water replenishment is stopped, and the yellow indicator light stops flashing. In this example, the liquid level sensor adopts an ultrasonic liquid level sensor, which can be installed outside the tank wall and isolated from the solution to avoid corrosion.

[0030] In this example, a vacuum pressure gauge 2 is provided on the negative pressure mechanism pipeline, and the pressure change in the box can be visually seen. A pressure regulating valve 3 is provided at the rear end of the vacuum pressure gauge 2, and the size of the negative pressure in the box can be conveniently adjusted. In this example, the aerator 30 adopts a day-type design, and its size is slightly smaller than the bottom of the box and close to the bottom of the box. A plurality of Φ2 equally spaced air outlets are processed on the pipe wall. The exhaust gas comes out of the air outlet to form a large number of small bubbles, which are fully contacted with the alkaline solution in the box to react;

[0031] A stainless steel water receiving pan 9 is provided below the liquid storage tank and the high-pressure blower.

When the liquid level reaches the predetermined position, the upper limit liquid level sensor sends the liquid level data to the controller, which controls the pure water inlet solenoid valve 1 and starts the high-pressure fan 6. A negative pressure is formed in the liquid storage tank. Under the action of atmospheric pressure, the exhaust gas discharged from the curing box reaches the bottom of the box through the aeration pipe, and forms a large number of small bubbles after passing through multiple Φ2 small holes. After the bubbles burst, they are fully in contact with the alkaline liquid. The condensable crystalline substances react with the alkaline solution to generate salts that dissolve in water. Before entering the high-pressure fan, the condensable crystalline substances in the exhaust gas are effectively filtered out and will not clog the pipeline. During the entire operation process, if the liquid level reaches the lower limit, the lower limit sensor will feed back to the microcontroller and automatically replenish water until the liquid level reaches the upper limit, and the water addition will automatically stop. If the temperature of the high-pressure fan is abnormal, the temperature sensor 10 will detect it and feed back to the microcontroller. The equipment will immediately alarm and notify the personnel to handle it.
