Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment, specifically to a quench tower for wet incineration. Background Technology

[0002] Wet incineration of waste involves adding water to turn waste into a sludge-like substance, which is then burned at a high temperature of around 800°C to convert the waste into ash and produce high-temperature flue gas and dust. Large-scale waste treatment plants can recover and utilize the high-temperature flue gas produced after incineration through energy conversion equipment, such as power generation. However, due to investment limitations, small-scale treatment plants typically allow the high-temperature flue gas and dust produced after incineration to be cooled and dusted before being naturally discharged. Because waste has a complex composition, the high-temperature flue gas produced after combustion contains acidic gases such as sulfur dioxide and nitrogen oxides. Furthermore, the harmful substance dioxins are highly susceptible to resynthesis in the temperature range of 300°C to 500°C. If the high-temperature flue gas is allowed to cool naturally and be freely discharged, it will cause secondary pollution to the surrounding environment. Therefore, most wet incineration processes currently use quench towers to rapidly cool the high-temperature flue gas to around 200°C to avoid the temperature window for dioxin formation. However, even after quenching, some acidic components remain in the steam, which will still have an environmental impact if not further treated. However, performing multiple separate treatments using multiple facilities not only reduces efficiency and increases processing costs but also poses a risk of secondary pollution. Therefore, it is necessary to improve the quench tower used in wet incineration. The goal is to integrate quenching, acid removal, and dust collection into a single unit, enabling rapid cooling of high-temperature flue gas, neutralization and deacidification of acidic gases in the flue gas, and filtration, separation, and collection of residual dust. This would improve operational efficiency, reduce costs, and avoid the risk of secondary pollution. This is the problem to be solved in this case. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model discloses a quench tower for wet incineration, comprising a quenching component, a deacidification component, a flue gas exhaust component, and a dust collection component. The quenching component and the deacidification component are each equipped with an inner cylinder and a water mist sprayer placed inside the inner cylinder, and an outer cylinder and a chemical mist sprayer placed inside the outer cylinder. The inner cylinder is placed inside the outer cylinder, which also contains a filter screen and a high-pressure backflushing component. High-temperature flue gas discharged from wet incineration and fed into the inner cylinder of the quenching component can be rapidly cooled by spraying water mist, and the rapidly cooled flue gas can be diffused into the outer cylinder. The deacidification component can neutralize and deacidify the flue gas dispersed in the outer cylinder by spraying alkaline chemical mist. This invention improves upon the quench tower used in wet incineration by using water mist sprayers inside the inner cylinder to spray water mist onto high-temperature flue gas, rapidly cooling it. The cooled flue gas then diffuses directly into the outer cylinder, where alkaline chemical mist is sprayed by chemical mist sprayers to neutralize and deacidify the acidic gases in the flue gas. The filter screen, high-pressure backflushing components, exhaust components, and dust collection components inside the outer cylinder can filter and collect dust and particulate matter in the flue gas, and the filter screen can be cleaned by high-pressure backflushing when necessary. This improves operational efficiency, reduces costs, and avoids the risk of secondary pollution.

The inner cylinder 11 can be inserted into the cavity of the outer cylinder 21 through the bottom hole of the bottom wall of the outer cylinder 21 and is fixedly connected to the bottom wall of the outer cylinder 21. There is a gap between the peripheral wall of the inner cylinder 11 and the peripheral wall of the outer cylinder 21. The aerosol spraying component 23 is provided with a second disc-shaped liquid supply pipe 231 and a second spray nozzle 232. There are several second spray nozzles 232, which are distributed and connected below the second disc-shaped liquid supply pipe 231 and connected to the pipe of the second disc-shaped liquid supply pipe 231. The second disc-shaped liquid supply pipe 231 is a disc-shaped mesh component consisting of several circular pipes connected end to end and interconnected by a transverse pipe. The diameter of the several circular pipes increases sequentially and is arranged in concentric circles from the inside to the outside. An inlet pipe that can be connected to an external liquid supply network is provided on its periphery. The outer top cover 22 is spherical in shape, positioned above the outer cylinder 21 and detachably and sealingly connected to it. The high-pressure backflush component 25 includes an air pipe 251 and air nozzles 252. The air pipe 251 is arranged in a serpentine pattern on the back of the outer top cover 22.

The filter screen 24 is positioned between the high-pressure backflush component 25 and the aerosol spray component 23 and detachably connected to the inner wall of the outer cylinder 21.

[0030] like Figure 1 , Figure 4 and Figure 7 As shown, the smoke exhaust assembly 3 of this utility model is provided with an adsorption box 31 and an exhaust fan 32. The adsorption box 31 is filled with activated carbon and is placed on top of the outer top cover 22. Its input end is connected to the outer cylinder 21 by a pipe, and its output end is connected to the exhaust fan 32 by a pipe with a valve.

[0031] like Figure 1 , Figure 4 and Figure 8 As shown, the dust collection assembly 4 of this utility model is provided with a dust pump 41 and a dust collection box 42. The dust collection box 42 is provided with a dust collection bag. The input end of the dust pump 41 is connected to the bottom of the outer cylinder 21 by a pipe with a valve, and the output end of the dust pump 41 is connected to the dust collection bag in the dust collection box 42 by a pipe.

[0032] The wet incineration quench tower described in this utility model can also be equipped with a temperature sensor for temperature detection and a control system for automatic control. Both temperature detection and automatic control are known technologies.

[0033] The usage method of this quench tower for wet incineration is as follows:

[0034] In use, first open the valves on the inlet pipe 14 and the pipes on the exhaust assembly 3; close the valves on the drain port at the bottom of the inner cylinder 11 and the pipes on the dust collection assembly 4; close the external air supply port that supplies compressed air to the high-pressure backflush unit 25. Open the external water supply valve that supplies water to the water mist sprayer 13 and the external chemical supply valve that supplies alkaline chemicals to the chemical mist sprayer 23, so that the water mist sprayer 13 and the chemical mist sprayer 23 begin to spray; turn on the exhaust fan 32. At this time, the high-temperature flue gas discharged from the external wet incineration of waste enters the inner cylinder 11 of the rapid cooling assembly 1 through the inlet pipe 14, and the water mist sprayer 13 sprays water mist to rapidly cool the high-temperature flue gas to a window temperature of about 200°C, which avoids the generation of dioxins. At this time, the solid matter mixed in the smoke and dust settles, while the gaseous smoke and dust rises and diffuses through the flow holes 111 on both sides of the inner cylinder 11 into the outer cylinder 21 of the deacidification component 2. There, the gaseous gas is neutralized by the alkaline mist sprayed by the mist sprayer 23 inside the outer cylinder 21, thus deacidifying and cooling down again. The solid matter formed after the neutralization reaction settles, while the gaseous smoke and dust continues to rise and is filtered by the filter screen 24. At this time, the flue gas passes through the filter screen 24, is adsorbed by the adsorption box 31, and is extracted and discharged by the exhaust fan 32. The residue intercepted by the filter screen 24 settles to the bottom of the outer cylinder 21 or adheres to the filter screen 24.

[0035] If the filter screen 24 becomes clogged and needs cleaning, close the valve on the smoke inlet pipe 14 and the valve on the exhaust assembly 3; stop the water mist sprayer 13 and the chemical mist sprayer 23; open the valve on the dust collection assembly 4; start the dust collection pump 41 of the dust collection assembly 4; open the external air supply port that supplies compressed air to the high-pressure backflush unit 25. At this time, the high-pressure backflush unit 25 can blow air in reverse high pressure onto the filter screen 24 from above, causing the residue attached to the filter screen 24 to fall off and fall into the bottom of the outer cylinder 21; the dust collection pump 41 of the dust collection assembly 4 can suck out the residue and collect it by the dust collection box 42; open the valve on the drain port at the bottom of the inner cylinder 11, and the residue discharged from the drain port at the bottom of the inner cylinder 11 can be collected separately.

[0036] This invention improves the quench tower for wet incineration by placing the inner cylinder 11 of the quenching component 1, equipped with a water mist sprayer 13, inside the outer cylinder 21 of the deacidification component 2, which is equipped with a chemical mist sprayer 23, a filter screen 24, and a high-pressure backflushing component 25. The flue gas exhaust component 3 and the dust collection component 4 are connected to the top and bottom of the outer cylinder 21, respectively. The water mist sprayer 13 in the inner cylinder 11 sprays water mist onto the high-temperature flue gas to rapidly cool it down. The rapidly cooled flue gas diffuses directly into the outer cylinder 21, where the chemical mist sprayer 23 sprays alkaline chemical mist to neutralize the acidic gases in the flue gas and remove acid. The filter screen 24 and the high-pressure backflushing component 25 in the outer cylinder 21, as well as the flue gas exhaust component 3 and the dust collection component 4, can filter and collect dust and particulate matter in the flue gas, and the filter screen 24 can be cleaned by high-pressure backflushing when necessary. This improves operating efficiency, reduces costs, and avoids the risk of secondary pollution.

[0037] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
