Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas water washing treatment, and in particular relates to a waste gas treatment area water washing device and process based on automatic detection. Background Art

[0002] When a chemical plant is demolished, the waste gas concentration in some areas is high and cannot be directly demolished, otherwise the waste gas will enter the air and pollute the air. Therefore, before demolition, it is necessary to use a waste gas treatment device to treat the waste gas. The commonly used waste gas treatment device is a water washing device, which includes an acid-base waste gas washing tower;

[0003] The working principle of the acid-base waste gas scrubber is to separate the pollutants in the gas and convert them into harmless substances to achieve the purpose of purifying the gas. It belongs to the differential contact countercurrent type, and the filler in the tower body is the basic component for gas-liquid two-phase contact. After the gas outside the tower body enters the tower body, the gas enters the filler layer. There is spray liquid from the top and the front spray liquid on the filler layer, and a liquid film is formed on the filler. When the gas flows through the gaps in the filler, it contacts the filler liquid film and undergoes absorption or neutralization reaction. The filler layer can provide a large enough surface area without causing excessive resistance to the gas flow. The absorbed or neutralized gas is collected by the demister and discharged out of the tower through the air outlet;

[0004] However, this conventional acid-base waste gas scrubber has low waste gas water washing efficiency when the waste gas concentration is high, and dirt adheres to the inner wall during the waste gas treatment process, which will cause internal blockage over time, resulting in low waste gas treatment effect and inability to achieve self-cleaning.

DETAILED DESCRIPTION

[0025] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-8 , the present invention provides a technical solution: a water washing device and process for a waste gas treatment area based on automatic detection, including a waste gas processor, the waste gas processor including a water washing chamber 1, an air intake pipe 2, an air pump 3, a water pump 4, an exhaust pipe 5, and a circulating water pipe 6;

[0027] The exhaust pipe 5 is connected to the top of the water washing chamber 1, the air pump 3 is connected to the suction pipe 2, and is connected to the bottom pipe of the water washing chamber 1, the left end of the suction pipe 2 is connected to the suction bin 21, and the suction bin 21 is provided with a concentration detector, and the circulating water pipe 6 is connected to the left side below the water washing chamber 1;

[0028] A concentration detection module is provided inside the concentration detector, and the concentration detection module is used to detect the concentration of particulate matter in the exhaust gas according to the concentration detector. A water flow pipe 11 is connected to the upper part of the inner wall of the water washing chamber 1, and the water flow pipe 11 is connected to the water pump 4 pipeline, and the water pump 4 is connected to the external water source pipeline. The circulating water pipe 6 is connected to the water purifier, and the water purifier is connected to the external water pipeline. A plurality of nozzles 111 are connected below the water flow pipe 11, and a packing layer 12 is fixedly installed inside the water washing chamber 1, and the packing layer 12 is located below the nozzle 111;

[0029] The concentration detection module is electrically connected to the water pump 4;

[0030] The waste gas treatment area is closed, and then the air suction chamber 21 is placed in the waste gas treatment area. The air pump 3 is running, and air is sucked through the air suction pipe 2. The waste gas enters the air suction pipe 2 through the air suction chamber 21. Then the air pump 3 injects the waste into the water washing chamber 1 through the pipeline. The water pump 4 is running, and the external water source is drawn through the pipeline and injected into the water flow pipe 11. The water is then sprayed from the nozzle 111. The packing layer 12 is the basic component for gas-liquid two-phase contact. After the waste gas enters the water washing chamber 1, the gas enters the packing layer 12, and there is spray liquid from the top on the packing layer 12 , and a liquid film is formed on the packing layer 12. When the gas flows through the gaps in the packing, it contacts the packing liquid film and undergoes absorption or neutralization reaction. The packing layer 12 can provide a sufficiently large surface area without causing excessive resistance to the gas flow, thereby absorbing harmful substances in the exhaust gas. The gas after water washing is then discharged out of the tower through the exhaust pipe 5. The water generated by the spraying and the absorbed harmful substances fall to the bottom of the inner wall of the water washing chamber 1, and then are discharged from the water washing chamber 1 through the circulating water pipe 6, and then purified by a water purifier for easy reuse and cost reduction;

[0031] The power of the water pump 4 changes with the concentration of particulate matter in the exhaust gas detected by the concentration detection module. The greater the concentration of particulate matter in the exhaust gas, the stronger the operating power of the water pump 4 and the greater the spraying efficiency of the nozzle 111. On the one hand, it ensures that the exhaust gas is fully purified. On the other hand, with less particulate matter in the exhaust gas, it can reduce water consumption and further reduce costs.

[0032] An isolation chamber 13 is fixedly installed at the bottom of the inner wall of the washing chamber 1; the isolation chamber 13 includes a motor 131, an output rod 132, a rotating rod 133, and a scraper 134;

[0033] The motor 131 is fixedly mounted on the bottom of the inner wall of the isolation chamber 13, the output rod 132 is fixedly connected to the output end of the motor 131, the scraper 134 is fixedly mounted on the outer side of the rotating rod 133, and the outer end is in contact with the inner wall of the washing chamber 1, a chute 135 is provided inside the upper part of the output rod 132, a docking rod 136 is fixedly mounted on the bottom end of the rotating rod 133, and the docking rod 136 is slidably connected in the chute 135, and notches are provided on the left and right sides of the chute 135, and limit blocks are provided on the left and right sides of the docking rod 136, and the rotating rod 133 is limited by the limit blocks and the notches, and the concentration detection module is electrically connected to the motor 131;

[0034] During the process of washing the waste gas, the motor 131 runs, driving the output rod 132 to rotate, the output rod 132 drives the limit block to rotate through the notch of the slide slot 135, the limit block drives the rotating rod 133 to rotate through the docking rod 136, the rotating rod 133 drives the scraper 134 to rotate, and the scraper 134 scrapes the dirt attached to the inner wall of the washing chamber 1, so that the inner wall is kept clean to avoid affecting the waste gas treatment effect;

[0035] The higher the concentration of particulate matter in the exhaust gas, the faster the motor 131 rotates, thereby speeding up the cleaning efficiency of the inner wall of the water washing chamber 1 on the one hand, and on the other hand, the rotation speed of the motor 131 can be reduced for exhaust gas with less particulate matter, thereby reducing energy consumption.

[0036] Extrusion balls 137 are fixedly mounted on both the left and right sides of the rotating rod 133;

[0037] A slide rail 14 is fixedly installed on the right side of the inner wall of the isolation chamber 13, a slider is slidably connected to the inner wall of the slide rail 14, and a push rod 141 is fixedly installed on the left end of the slider, and the outer end of the push rod 141 is spherical and aligned with the extrusion ball 137;

[0038] When the rotating rod 133 rotates, it drives the squeezing ball 137 to rotate around its center until the squeezing ball 137 contacts the spherical part of the push rod 141 and rubs and squeezes each other. The squeezing ball 137 is subjected to force, so that the rotating rod 133 passes through the limit block of the home stem 136, so that the limit block slides upward in the notch of the slide groove 135, thereby driving the scraper 134 to move upward. After that, the squeezing ball 137 rotates until it is out of contact with the push rod 141, and the rotating rod 133 falls downward by its own weight, so that the scraper 134 moves up and down quickly, scraping the inner wall of the washing chamber 1 up and down, thereby enhancing the cleaning ability, and can squeeze the packing layer 12 to squeeze out the internal water, thereby enhancing the absorption effect of the exhaust gas and enhancing the purification ability.

[0039] A hydraulic chamber 15 is fixedly installed on the left side of the inner wall of the isolation chamber 13, a hydraulic plate 151 is slidably connected to the inner wall of the hydraulic chamber 15, a hydraulic rod 152 is fixedly installed above the hydraulic plate 151, the upper end of the hydraulic rod 152 is spherical and aligned with the extrusion ball 137, the hydraulic plate 151 is connected to the inner wall bottom of the hydraulic chamber 15 by a spring, and the bottom is filled with hydraulic oil;

[0040] A slide plate 16 is sleeved on the outer wall of the isolation chamber 13, and the slide plate 16 is slidably connected to the inner wall of the water washing chamber 1. A plurality of water flow holes 161 are provided on the surface of the slide plate 16. A telescopic chamber 17 is fixedly installed on the bottom of the inner wall of the water washing chamber 1. The upper end of the telescopic chamber 17 is fixed to the lower surface of the slide plate 16, and the telescopic chamber 17 is connected to the bottom pipeline of the hydraulic chamber 15.

[0041] Elastic springs 18 are fixedly installed on both sides of the bottom of the inner wall of the washing chamber 1, and a blocking plate 181 is fixedly installed on the upper end of the elastic spring 18. The blocking plate 181 is located below the plurality of water holes 161 and covers the plurality of water holes 161.

[0042] The water after washing flows to the bottom of the washing chamber 1 through the water flow hole 161 on the slide plate 16. When the squeezing ball 137 rotates through the rotating rod 133, it contacts and squeezes and rubs against the upper end of the hydraulic rod 152, so that the hydraulic rod 152 is forced to push the hydraulic plate 151 to slide downward along the inner wall of the hydraulic chamber 15. The liquid under the hydraulic plate 151 is squeezed and enters the telescopic chamber 17 through the pipeline, so that it stretches and drives the slide plate 16 to slide upward along the inner wall of the washing chamber 1. At the same time, the spring connecting the hydraulic plate 151 and the bottom of the inner wall of the hydraulic chamber 15 is deformed under force, and then the squeezing ball 137 is squeezed. 7 is out of contact with the hydraulic rod 152, the spring generates a reaction force to reset, and the liquid in the telescopic chamber 17 is extracted through the pipeline. The telescopic chamber 17 is shortened, so that the slide plate 16 moves downward, and the bottom of the slide plate 16 contacts the blocking plate 181. The blocking plate 181 is stressed so that the elastic spring 18 is deformed and generates a reaction force to block the water flow hole 161, so as to play the role of a one-way valve. After that, the water after washing is squeezed and discharged through the circulating water pipe 6. By squeezing the water after washing, it is prevented that particles block the circulating water pipe 6, so as to accelerate the water recovery efficiency.

[0043] A telescopic rod 19 is fixedly installed above the push rod 141, and the upper end of the telescopic rod 19 is fixedly installed above the inner wall of the isolation chamber 13;

[0044] The telescopic rod 19 is connected to the upper pipeline of the hydraulic chamber 15, and a pressure valve is arranged in the pipeline. The upper part of the hydraulic chamber 15 is connected to the external pipeline, and a one-way valve is arranged in the pipeline. The telescopic rod 19 is connected to the external control valve pipeline.

[0045] A push rod 142 is welded in the middle of the spherical portion at the outer end of the push rod 141;

[0046] When the hydraulic plate 151 slides up and down along the inner wall of the hydraulic chamber 15, gas is continuously drawn from the outside above the hydraulic plate 151 and injected into the pipeline until the gas pressure in the pipeline reaches the pressure valve's bearing limit and opens. The gas quickly passes through the pipeline into the telescopic rod 19, thereby driving the push rod 141 to move upward quickly. The push rod 141 slides upward along the slide rail 14 through the slider, driving the push rod 142 to move upward quickly. After that, the external control valve is immediately opened, and the gas in the telescopic rod 19 is quickly released, so that the push rod 142 moves up and down quickly. The push rod 142 pushes against the scraper 134 and moves upward quickly, thereby further strengthening the extrusion force on the packing layer 12 and fully squeezing out the internal water.

[0047] The water washing process of the water washing device in the waste gas treatment area includes the following steps:

[0048] Step S1, the waste gas treatment area is closed, and then the air suction bin 21 is placed in the waste gas treatment area;

[0049] Step S2, the air pump 3 is operated to inhale air through the air suction pipe 2, and the waste gas enters the air suction pipe 2 through the air suction bin 21, and then the air pump 3 injects the waste gas into the water washing chamber 1 through the pipeline, the water pump 4 is operated, water is sprayed from the nozzle 111, and the packing layer 12 absorbs harmful substances in the waste gas;

[0050] Step S3, while the motor 131 is running, the scraper 134 rotates through the rotating rod 133 to scrape off the dirt attached to the inner wall of the washing chamber 1 to ensure the cleanliness of the washing device;

[0051] Step S4, the gas after water washing is discharged out of the tower through the exhaust pipe 5, the water generated by the spraying and the absorbed harmful substances fall to the bottom of the inner wall of the water washing chamber 1, and then discharged from the water washing chamber 1 through the circulating water pipe 6, and finally purified by the water purifier.
