Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas treatment, and particularly relates to a treatment system for high-temperature waste gas in a flue. Background Technique

[0002] With the continuous development of industrial production, many enterprises will generate a large amount of high-temperature waste gas during the production process. High-temperature waste gas is generated by oxidation reactions under high-temperature conditions during processes such as combustion, heat treatment, and smelting. Generally, the temperature of high-temperature waste gas exceeds 800°C. It has a relatively high temperature, is prone to causing radiant heat and thermal radiation damage, and contains a large amount of harmful gases and particulate matter, such as sulfur dioxide, nitrogen oxides, benzene, styrene, etc., which pose a great threat to the environment and human health. If these high-temperature waste gases are not treated promptly and effectively, they will not only pollute the atmospheric environment but also may pose potential safety hazards of fire or explosion.

[0003] Existing treatment systems for flue waste gas, for example, the Chinese invention patent with the publication number CN106390705A discloses a flue gas desulfurization waste gas treatment system, including: a flue gas inlet passage, on which a dust removal and purification net is provided. The flue gas passing through the dust removal and purification net enters the purification tower through a pipeline. A heat exchanger A is connected between the purification tower and the flue gas inlet passage, and a valve structure is provided at the connection between the flue gas inlet passage and the purification tower. The purification tower is in the form of a cylinder structure, and inside the shell, a spray layer, a packing layer, and a circulation tank are arranged from top to bottom. The present invention is a flue gas desulfurization waste gas treatment system with a compact design structure, and the desulfurization efficiency can be above 90%, further reducing the discharge of sulfur dioxide, and is suitable for waste gas treatment of enterprises in various industries in China.

[0004] However, this device only sets a group of purification towers and spray layers to cool the waste gas. Due to the relatively high temperature of the waste gas and the limited time passing through the spray layer, it is difficult to ensure that the temperature of the waste gas can be reduced to a degree meeting the emission standards. Moreover, when spraying and cooling the waste gas, since the inside of the purification tower is a closed space, when water encounters high-temperature waste gas, the water will vaporize due to the high temperature and generate a large amount of water vapor, but this device is difficult to collect and utilize this water vapor. In view of this, we have proposed a treatment system for high-temperature waste gas in a flue for treating high-temperature waste gas. Summary of the Invention

[0008] In the above technical solution, further, a valve is installed at one end of the first infusion pipe close to the first cooling tower, a temperature sensor is installed on the front side of the first cooling tower, the inside of the temperature sensor is a kind of NTC thermistor, and its characteristics are: low cost and sensitive reaction, and it is widely used in the temperature monitoring of industrial coolant, and it can accurately monitor the temperature of the coolant inside the first cooling tower, and control the first water pump and the valve according to the detection result of the temperature sensor.

[0009] In the above technical solution, further, the spraying assembly includes a second water pump, the second water pump is arranged on the front side of the second cooling tower, the top end of the second water pump is connected with a first water delivery pipe, and the other end of the first water delivery pipe is fixedly connected with a first water distribution pipe. And there are two sets of upper and lower first water distribution pipes. Two sets of upper and lower first fixing rings are fixedly installed on the inner wall of the second cooling tower.

[0010] In the above technical solution, further, the water collection assembly includes water walls, the water walls are fixedly installed at the top inside the second cooling tower, and there are two sets of upper and lower water walls. Four ventilation holes are opened on the water walls. A clamping groove is opened at the center of the top of the water wall. A motor is installed at the top of the second cooling tower.

[0012] In the above technical solution, further, the bottom surfaces of the two water walls are both set to be funnel-shaped and concave inward. The adjusting plate fits the surface of the water wall. The shape and size of the adjusting plate are the same as those of the ventilation holes. The inner walls of the bottoms of the water wall and the adjusting plate are very smooth, so that water droplets can flow downward into the water collection tank through the inclined surfaces at the bottoms of the water wall and the adjusting plate.

[0013] In the above technical solution, further, the upper and lower groups of the water-cooled walls and the regulating plates are arranged in a staggered manner, and the staggering angle is 45 degrees. The waste gas together with the water vapor will first contact the bottom of the lower water-cooled wall and the regulating plate, and there will also be gas directly passing through the lower ventilation holes. However, the gas directly passing through will contact the bottom of the upper water-cooled wall and the regulating plate, which can make the contact time between the gas and the water collection assembly longer and more complete, and is beneficial to improving the water collection effect.

[0014] In the above technical solution, further, second fixing rings are fixedly installed at the bottoms of the two groups of water-cooled walls, and water collecting grooves are formed at the tops of the second fixing rings. Second water distribution pipes are communicated with the rear sides of the two groups of second fixing rings.

[0015] In the above technical solution, further, the dust removal assembly includes slots, which are formed on one side of the dust removal bin. There are two groups of slots. Frames are inserted into the slots, and dust bags are installed inside the frames. A mounting plate is fixedly installed on one side of the frame, and the mounting plate is attached to the outer surface of the dust removal bin. Screws are inserted into the upper and lower sides of the mounting plate, and the mounting plate is fixed on one side surface of the dust removal bin through the screws. A handle is fixedly installed on the mounting plate. The function of blocking the dust in the waste gas is realized through the two dust bags, and at the same time, it is convenient to clean the dust on the dust bags.

[0016] The beneficial effects of the present invention are as follows: 1. For the treatment system of high-temperature waste gas in the flue, after the induced draft fan is started, the induced draft fan can generate suction and suck the waste gas from one end of the air inlet towards the direction of the induced draft fan. The waste gas will pass through three groups of cooling pipes. The coolant inside the first cooling tower will cool the high-temperature waste gas inside the cooling pipes. The temperature sensor will monitor the liquid temperature inside the first cooling tower in real time. When it is monitored that the temperature of the coolant rises to 100 degrees, the first water pump and the valve can be opened. The coolant inside the first cooling tower will flow into the chiller through the first liquid conveying pipe. The chiller will cool the coolant, and the cooled coolant will enter the first water pump through the second liquid conveying pipe and re-enter the first cooling tower through the third liquid conveying pipe, so as to achieve the purpose of cold circulation. The function of pre-cooling the waste gas can be realized through the three groups of cooling pipes; 2. For the treatment system of high-temperature waste gas in the flue, after passing through the cooling pipe, the waste gas will enter the second cooling tower through the first connecting pipe. The second water pump and motor can be started. The second water pump will pump water from the water tank and input it into the first water delivery pipe. The water inside the first water delivery pipe can be transmitted to the spray head through the first water distribution pipe, so that the spray head sprays water downward inside the second cooling tower to cool the rising waste gas. When the water contacts the high-temperature waste gas, the water droplets will vaporize to form water vapor and rise together with the waste gas. The waste gas and water vapor will contact the bottom of the water-cooled wall together. When the water vapor meets the cold, it will liquefy into water droplets and adhere to the bottom surfaces of the water-cooled wall and the adjusting plate. The remaining waste gas will then pass through the ventilation holes and enter the second connecting pipe. The water droplets at the bottom of the water-cooled wall and the adjusting plate will flow downward along the inclined plane into the water collecting tank. When the water in the water collecting tank accumulates to a certain extent, it will flow into the second water distribution pipe and then flow downward through the second water delivery pipe into the water collecting bucket. After being filtered by the filter screen, it will flow back into the water tank through the third water delivery pipe, realizing the recycling of water. This design can recycle and reuse water resources, improving the environmental protection of the device; 3. For the treatment system of high-temperature waste gas in the flue, by detecting the air pressure at the bottom of the second cooling tower through the detection head, the change of the air pressure inside the second cooling tower can be observed through the pressure sensor, so as to adjust the opening size of the ventilation holes. When the gas flowing into the second cooling tower from the first connecting pipe becomes less, the air pressure will also decrease accordingly. The output end of the motor can drive the rotating rod to rotate, and the rotating rod can drive the adjusting plate and the clamping ring to rotate. The clamping ring will rotate in the clamping groove. At the same time, the adjusting plate will rotate towards the bottom of the ventilation hole, covering a part of the bottom of the ventilation hole, thereby reducing the air outlet area of the ventilation hole. This can make the contact area between the waste gas and water vapor and the bottom of the water-cooled wall and the adjusting plate larger, increasing the efficiency of water vapor liquefaction. When the gas flowing into the second cooling tower from the first connecting pipe becomes more, just make the adjusting plate completely coincide with the bottom of the water-cooled wall, making the air outlet area of the ventilation hole the largest, and it can adjust the opening size according to the amount of gas, improving the flexibility of the device; 4. For the treatment system of high-temperature waste gas in the flue, after the waste gas enters the second connecting pipe, the induced draft fan will suck the waste gas in the second connecting pipe and discharge it into the dust removal bin. In the dust removal bin, the waste gas will be filtered by two groups of cloth bags to filter the dust in the waste gas, and finally the waste gas will be discharged through the chimney. And after use, the screws on the upper and lower sides of the mounting plate can be unscrewed, and then hold the handle and pull out the frame from the slot, realizing the dust removal function and being able to clean the cloth bag very conveniently.

When it is detected that the temperature of the coolant rises to 100 degrees, the first water pump 12 and the valve 14 can be turned on. The coolant inside the first cooling tower 1 will flow into the chiller 10 through the first infusion pipe 9. The chiller 10 will cool the coolant. After cooling, the coolant will enter the first water pump 12 through the second infusion pipe 11 and re-enter the first cooling tower 1 through the third infusion pipe 13, thus achieving the purpose of cold circulation. The function of pre-cooling the waste gas can be realized through the three groups of cooling pipes 16; After passing through the cooling pipes 16, the waste gas will enter the second cooling tower 4 through the first connecting pipe 3. The second water pump 17 and the motor 23 can be started. The second water pump 17 will pump water from the water tank 46 and input it into the first water delivery pipe 18. The water inside the first water delivery pipe 18 can be transmitted to the spray head 22 through the first water distribution pipe 19, causing the spray head 22 to spray water downward inside the second cooling tower 4 to cool the rising waste gas. When the water contacts the high-temperature waste gas, the water droplets will vaporize to form water vapor and rise together with the waste gas. The waste gas and the water vapor will contact the bottom of the water-cooled wall 25 together. When the water vapor cools down, it will liquefy into water droplets again and adhere to the bottom surfaces of the water-cooled wall 25 and the adjusting plate 29. The remaining waste gas will then pass through the ventilation holes 26 and enter the second connecting pipe 5. The water droplets at the bottoms of the water-cooled wall 25 and the adjusting plate 29 will flow downward along the inclined surface into the water collecting tank 32. When the water inside the water collecting tank 32 accumulates to a certain extent, it will flow into the second water distribution pipe 33 and then flow downward through the second water delivery pipe 34 into the water collecting bucket 35. After being filtered by the filter screen 36, it will flow back into the water tank 46 through the third water delivery pipe 38, realizing the circulation of water. This design can recycle and reuse water resources, improving the environmental protection of the device; By detecting the air pressure at the bottom of the second cooling tower 4 through the detection head 40, the change in the internal air pressure of the second cooling tower 4 can be observed through the air pressure sensor 39, so as to adjust the opening size of the ventilation hole 26. When the gas flowing into the second cooling tower 4 from the first connecting pipe 3 becomes less, the air pressure will also decrease accordingly. The output end of the motor 23 can drive the rotating rod 24 to rotate, and the rotating rod 24 can drive the adjusting plate 29 and the snap ring 30 to rotate. The snap ring 30 will rotate in the card slot 27, and at the same time, the adjusting plate 29 will rotate towards the bottom of the ventilation hole 26, covering a part of the bottom of the ventilation hole 26, thereby reducing the air outlet area of the ventilation hole 26. This can make the contact area between the waste gas and water vapor and the bottom of the water-cooled wall 25 and the adjusting plate 29 larger, increasing the efficiency of water vapor liquefaction. When the gas flowing into the second cooling tower 4 from the first connecting pipe 3 becomes more, just make the adjusting plate 29 completely coincide with the bottom of the water-cooled wall 25, so that the air outlet area of the ventilation hole 26 becomes the largest. It can adjust the opening size according to the amount of gas, improving the flexibility of the device; After the waste gas enters the second connecting pipe 5, the induced draft fan 6 will suck the waste gas in the second connecting pipe 5 and discharge it into the dust removal bin 7. In the dust removal bin 7, the waste gas will be filtered through two groups of cloth bags 43 to filter the dust in the waste gas, and finally the waste gas will be discharged through the chimney 8. And after use, the screws on the upper and lower sides of the mounting plate 44 can be unscrewed, and then hold the handle 45 to pull out the frame 42 from the slot 41. While realizing the dust removal function, it is very convenient to clean the cloth bags 43.
