Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically relating to a waste gas treatment device for high-concentration industrial wastewater. Background Technology

[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals; wastewater from the electroplating industry contains cyanide and chromium, and other heavy metals; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains a variety of toxic substances, it pollutes the environment and poses a great threat to human health. Therefore, it is necessary to develop comprehensive utilization methods to turn harm into benefit. Appropriate purification measures should be taken according to the composition and concentration of pollutants in the wastewater before it can be discharged.

[0007] The first exhaust gas treatment component includes a water tank, a water injection pipe, a first water pipe, a first electric valve, a first water pump, a second water pipe, a second electric valve, a second water pump, and a cleaning nozzle.

When the exhaust gas concentration is high, the ventilation speed is increased to avoid the accumulation of exhaust gas inside the wastewater sludge treatment tank, which could cause safety hazards. It can also prevent exhaust gas from overflowing into the production workshop and affecting the staff. Through the combined use of a first water pump, a first electric valve, a water tank and equipment program, water can be used to pre-treat the exhaust gas generated by sludge, filtering harmful substances in the exhaust gas into the water.

[0018] By using the second water pump, the second electric valve, the cleaning nozzle, and the equipment program in conjunction, the usage time of the pretreatment water can be adjusted according to the different concentrations of the exhaust gas. When the exhaust gas concentration is low, the usage time of the pretreatment water can be extended to reduce water waste and achieve energy conservation and emission reduction. When the exhaust gas concentration is high, the water can be changed regularly to prevent the amount of dirt in the water from affecting the pretreatment effect. The pretreatment water can also be used to clean the inclined surface inside the wastewater sludge treatment tank to prevent sludge from accumulating and drying and clumping. At the same time, it can keep the accumulated sludge moist, making it easier for staff to shovel it out and collect it centrally. Attached Figure Description

One end of the second water pipe 24 is connected to one side of the exhaust gas treatment chamber 14, and the other end passes through the wastewater sludge treatment tank 1 and is connected to the cleaning nozzle 26.

The waste gas treatment tank 31 is also placed on the production workshop floor, located on the other side of the wastewater and sludge treatment tank 1. The interior of the waste gas treatment tank 31 is hollow. The outlet pipe 311 is located on the outside of the waste gas treatment tank 31 for discharging the treated gas.

The placement frame 33 is detachably installed in the waste gas treatment tank 31, and the activated carbon blocks 34 are detachably installed in the placement frame 33 for cooperating in the secondary treatment of the waste gas.

[0040] The wastewater and sludge treatment tank 1 is powered by an external power source to drive the internal components.

[0041] The wastewater and sludge treatment tank 1 is also equipped with an equipment program that can control the opening and closing of the ventilation fan 15, the opening and closing of two sets of electric valves, and the start and stop of two sets of water pumps.

[0042] The ventilation fan 15, two sets of electric valves, two sets of water pumps, three sets of liquid level sensors, and air quality sensor 17 are all connected to the equipment program signal.

[0043] Exhaust gas pretreatment operations:

[0044] During industrial wastewater treatment, a large amount of sludge and impurities are filtered out. Workers need to collect this sludge for subsequent recycling. First, workers use hoisting equipment to move the wastewater sludge treatment tank 1 into the production workshop. Then, they turn on the workshop power, starting the wastewater sludge treatment tank 1 and the equipment program. Workers connect the sludge discharge pipe to the feed pipe 11, allowing the sludge to enter the wastewater sludge treatment tank 1 for centralized storage. Next, workers connect the workshop wastewater recovery pipe to the wastewater recovery pipe 18 to collect the wastewater from the sludge. During sludge storage, the equipment program uses an air quality sensor 17 to detect the concentration of exhaust gas in the wastewater sludge treatment tank 1 and compares it with a set value. The equipment program sets concentration values ​​A1, A2, and A3, where A1 is the minimum and A3 is the maximum, which can be adjusted according to specific needs. Adjustments are made to the rotation speed of the ventilation fan 15, which is B1, B2, and B3, with B1 being the minimum and B3 being the maximum. These can be adjusted according to specific needs. When the equipment program detects a concentration value of A1, it determines that the concentration of exhaust gas in the wastewater sludge treatment tank 1 is low and only ventilation is required. The equipment program first controls the first water pump 23 to start, the first electric valve 221 to open, and the second electric valve 241 to be closed. The first water pump 23 pumps the clean water in the water tank 21 into the first water pipe 22 and then into the exhaust gas treatment chamber 14. Then, the equipment program controls the ventilation fan 15 to start at a speed of B1. The ventilation fan 15 draws the exhaust gas from the wastewater sludge treatment tank 1 through two sets of first ventilation pipes 16 and sprays it out from two sets of second ventilation pipes 161 into the clean water in the exhaust gas treatment chamber 14 to pre-treat and filter the exhaust gas generated by sludge accumulation.

[0045] When the equipment program detects a concentration value of A2, the equipment program determines that the concentration of exhaust gas in the wastewater sludge treatment tank 1 has increased and that ventilation efficiency needs to be improved. The equipment program controls the speed of the ventilation fan 15 to be adjusted to B2. The ventilation fan 15 draws the exhaust gas from the wastewater sludge treatment tank 1 through two sets of first ventilation pipes 16 and then sprays it out from two sets of second ventilation pipes 161 into the clean water in the exhaust gas treatment chamber 14 to perform pretreatment and filtration of the exhaust gas generated by sludge accumulation.

[0046] When the equipment program detects a concentration value of A3, the equipment program determines that the concentration of exhaust gas in the wastewater sludge treatment tank 1 is high and that ventilation efficiency needs to be improved. The equipment program controls the speed of the ventilation fan 15 to be adjusted to B3. The ventilation fan 15 draws out the exhaust gas in the wastewater sludge treatment tank 1 through two sets of first ventilation pipes 16 and then sprays it out from two sets of second ventilation pipes 161 into the clean water in the exhaust gas treatment chamber 14 to perform pretreatment and filtration of the exhaust gas generated by sludge accumulation.

[0047] During the above operation, the equipment program detects the sludge level by using the signal values ​​of the first liquid level sensor 13 and the second liquid level sensor 131. When the equipment program detects that the sludge level only reaches the first liquid level sensor 13, the equipment program determines that the amount of sludge is small and there is no need to increase the ventilation efficiency. When the equipment program detects that the sludge level reaches the second liquid level sensor 131, the equipment program determines that the amount of sludge is large and the ventilation efficiency needs to be increased to avoid the accumulation of exhaust gas. The equipment program controls the speed of the ventilation fan 15 to be adjusted to B3. The ventilation fan 15 draws the exhaust gas from the wastewater sludge treatment tank 1 through two sets of first ventilation pipes 16 and sprays it out from the two sets of second ventilation pipes 161 into the clean water in the exhaust gas treatment chamber 14 to perform pretreatment and filtration of the exhaust gas generated by the accumulation of sludge.

[0048] By using the ventilation fan 15, air quality sensor 17 and equipment program in conjunction with each other, the ventilation speed can be changed according to the different concentration values ​​of the exhaust gas generated by the sludge. When the exhaust gas concentration is low, only the lowest wind speed is needed for circulating ventilation, reducing energy consumption and maintaining gas circulation in the wastewater sludge treatment tank 1. When the exhaust gas concentration is high, the ventilation speed is increased to prevent exhaust gas from accumulating inside the wastewater sludge treatment tank 1 and causing safety hazards. It can also prevent exhaust gas from overflowing into the production workshop and affecting the staff. By using the first water pump 23, first electric valve 221, water tank 21 and equipment program in conjunction with each other, water can be used to pre-treat the exhaust gas generated by the sludge, filtering the harmful substances in the exhaust gas into the water.

[0049] Secondary treatment of exhaust gas:

[0050] After completing the above operations, the equipment program controls a secondary treatment operation. The exhaust gas, after being filtered by the water, enters the third ventilation pipe 321 from the exhaust gas treatment chamber 14, and then enters the exhaust gas treatment tank 31. The activated carbon block 34 in the exhaust gas treatment tank 31 can perform secondary filtration on the exhaust gas, removing harmful substances from the exhaust gas. The treated gas is discharged to the outside from the exhaust pipe 311. During the above operations, the equipment program performs a timing operation. The equipment program sets the time to T1, T2, and T3, where T1 is the minimum value and T3 is the maximum value, which can be adjusted according to specific needs. When the equipment program detects that the concentration of the exhaust gas is A1, the equipment program determines that the concentration of the exhaust gas is low and that frequent water replacement is not necessary. The equipment program sets the timing time to T3. When T3 is up, the equipment program controls the second water pump 25 to start and the second electric valve 241 to open. 25. The pretreatment water in the exhaust gas treatment chamber 14 is pumped into the second water pipe 24 and then sprayed from the cleaning nozzle 26 into the wastewater sludge treatment tank 1. At this time, the pretreatment water will flow out from the wastewater recovery pipe 18 at the bottom of the wastewater sludge treatment tank 1 into the workshop wastewater recovery pipe, automatically replacing the pretreatment water to avoid the impact of too much dirt in the water on the pretreatment effect. At the same time, the pretreatment water can be used to clean the inclined surface inside the wastewater sludge treatment tank 1 to avoid sludge accumulation leading to drying and clumping. After the pretreatment water is sprayed out, the equipment program controls the second water pump 25 and the second electric valve 241 to close, and the first water pump 23 and the first electric valve 221 to open. The first water pump 23 pumps the clean water in the water tank 21 into the first water pipe 22 and then into the exhaust gas treatment chamber 14. When the water level reaches the third liquid level sensor 162, the equipment program controls the first water pump 23 and the first electric valve 221 to close.

[0051] When the equipment program detects that the concentration of the exhaust gas is A2, it determines that the exhaust gas concentration has increased and a water change operation is required. The equipment program sets a timer for T2. When T2 expires, the equipment program controls the second water pump 25 to start and the second electric valve 241 to open. The second water pump 25 pumps the pretreatment water in the exhaust gas treatment chamber 14 into the second water pipe 24, and then sprays it out from the cleaning nozzle 26 into the wastewater and sludge treatment tank 1. At this time, the pretreatment water will flow out from the wastewater recovery pipe 18 at the bottom of the wastewater and sludge treatment tank 1 into the workshop wastewater recovery pipe, automatically replacing the pretreatment water and avoiding... The presence of pollutants in the water body can affect the pretreatment effect. At the same time, the pretreatment water can be used to clean the inclined surface inside the wastewater sludge treatment tank 1 to avoid sludge accumulation leading to drying and clumping. After the pretreatment water is sprayed out, the equipment program controls the second water pump 25 and the second electric valve 241 to close, and the first water pump 23 and the first electric valve 221 to open. The first water pump 23 pumps the clean water in the water tank 21 into the first water pipe 22 and then into the waste gas treatment chamber 14. When the water level reaches the third liquid level sensor 162, the equipment program controls the first water pump 23 and the first electric valve 221 to close.

[0052] When the equipment program detects that the concentration of the exhaust gas is A3, it determines that the exhaust gas concentration is high and a water change operation is required. The equipment program sets a timer for T1. When T1 expires, the equipment program controls the second water pump 25 to start and the second electric valve 241 to open. The second water pump 25 pumps the pretreatment water in the exhaust gas treatment chamber 14 into the second water pipe 24, and then sprays it out from the cleaning nozzle 26 into the wastewater and sludge treatment tank 1. At this time, the pretreatment water will flow out from the wastewater recovery pipe 18 at the bottom of the wastewater and sludge treatment tank 1 into the workshop wastewater recovery pipe, automatically replacing the pretreatment water and avoiding... The presence of pollutants in the water body can affect the pretreatment effect. At the same time, the pretreatment water can be used to clean the inclined surface inside the wastewater sludge treatment tank 1 to avoid sludge accumulation leading to drying and clumping. After the pretreatment water is sprayed out, the equipment program controls the second water pump 25 and the second electric valve 241 to close, and the first water pump 23 and the first electric valve 221 to open. The first water pump 23 pumps the clean water in the water tank 21 into the first water pipe 22 and then into the waste gas treatment chamber 14. When the water level reaches the third liquid level sensor 162, the equipment program controls the first water pump 23 and the first electric valve 221 to close.

[0053] By using the second water pump 25, the second electric valve 241, the cleaning nozzle 26, and the equipment program in conjunction with the equipment, the usage time of the pretreatment water can be adjusted according to the different concentrations of the exhaust gas. When the exhaust gas concentration is low, the usage time of the pretreatment water can be extended to reduce water waste and achieve energy conservation and emission reduction. When the exhaust gas concentration is high, the water can be changed regularly to prevent the amount of dirt in the water from affecting the pretreatment effect. The pretreatment water can also be used to clean the inclined surface inside the wastewater sludge treatment tank 1 to prevent sludge from accumulating and drying and clumping. At the same time, it can keep the accumulated sludge moist, making it easier for staff to shovel it out and collect it centrally.
