Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a cooling device to prevent combustion during the operation of an activated carbon adsorption device. Background Technology

[0002] In the field of environmental treatment, activated carbon adsorption technology is widely used to remove organic matter from waste gas. However, the activated carbon adsorption process is not heatless, but rather a significant exothermic process. When organic matter is adsorbed by activated carbon and oxidized on its surface, a large amount of heat is released. For some complex compounds, their adsorption and reaction on the activated carbon surface may further exacerbate the heat release due to incompatible reactions. This exothermic process is particularly pronounced when the concentration of chemicals in the waste gas is high.

[0003] Heat balance is a key factor determining whether combustion will occur during activated carbon adsorption. If the generated heat cannot be transferred effectively and in a timely manner, it will accumulate in the activated carbon bed, causing the bed temperature to rise. When the temperature reaches the ignition point of the activated carbon, it may ignite the combustible waste gas mixture or cause the activated carbon to spontaneously combust.

[0004] During adsorption, the primary mode of heat transfer is convection. However, when convection conditions are unfavorable, such as low airflow, heat transfer efficiency decreases, further exacerbating heat accumulation and temperature increases. Therefore, effectively managing and transferring the heat generated during activated carbon adsorption to prevent excessively high carbon bed temperatures is a significant challenge for ensuring the safe operation of activated carbon adsorption devices.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within its scope.

[0029] In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, a cooling device is provided to prevent combustion during the operation of an activated carbon adsorption device, such as... Figure 1 include:

[0030] Cooling circulation pipe 1 is installed in activated carbon adsorption device 100;

[0031] The spraying device 2 is installed on the wall of the cooling circulation pipe 1, and the spraying direction is towards the activated carbon 110 in the activated carbon adsorption device 100.

[0032] Specifically, the gas enters the activated carbon adsorption device 100 for adsorption and filtration. In order to avoid heat generation and spontaneous combustion during the adsorption process, a cooling circulation pipe 1 is added in the embodiment to cool the activated carbon 110. The location of the cooling circulation pipe 1 is buried in the activated carbon 110 to improve the cooling efficiency. The cooling equipment connected to the cooling circulation pipe 1 is not shown in the figure. Existing heat exchange plates and other devices can be used to circulate and cool the cooling medium.

[0033] However, when the convection conditions in the activated carbon adsorption device 100 are unfavorable, the heat transfer efficiency will decrease, further aggravating the accumulation of heat and the rise in temperature, exceeding the cooling working limit of the cooling circulation pipe 1. Therefore, the spray device 2 is further added to spray the cooling medium directly onto the activated carbon bed when the temperature is too high, thereby improving the heat transfer efficiency and effectively managing heat even under unfavorable convection conditions.

[0034] In a preferred embodiment of this invention, the spraying device 2 includes:

[0035] Multiple spray nozzles 21 are arranged sequentially along the length of the cooling circulation pipe 1, and each spray nozzle 21 is equipped with an adjustable valve on its cover.

[0036] The injection controller 22 is located at the bottom of the activated carbon adsorption device 100, and is connected to each adjustable valve via a transmission mechanism.

[0037] Specifically, such as Figures 1-2 As shown, the center of the activated carbon bed is the most prone to heat accumulation leading to spontaneous combustion. Therefore, a spray controller is installed at the bottom of the activated carbon adsorption device 100, which is the center of the activated carbon bed. This controller can promptly open the adjustable valve of the spray nozzle when the temperature rises, so that the cooling medium can be directly sprayed onto the activated carbon bed.

[0038] Furthermore, in a preferred embodiment of the present invention, the injection controller 22 includes:

[0039] Trachea 221, the bottom of trachea 221 is closed and the top is open;

[0040] A sealing piston 222 extends into the trachea 221 from the top of the trachea 221, forming an air-filled air chamber 223 between the sealing piston 222 and the bottom of the trachea 221.

[0041] A push rod 2221 is provided on the side of the sealing piston 222 facing the top of the air pipe 221, and the push rod 2221 is connected to each adjustable valve in a transmission connection.

[0042] Specifically, such as Figure 2 As shown, the sealing piston 222 slides in the air tube. As the temperature of the activated carbon 110 gradually increases, the air in the air chamber 223 will expand in volume due to thermal expansion and contraction, pushing the sealing piston 222 toward the top of the air tube 221.

[0043] Similarly, as the temperature of activated carbon 110 gradually decreases, the air in the air chamber 223 will shrink in volume due to thermal expansion and contraction, pulling the sealing piston 222 back towards the bottom of the air pipe 221.

[0044] The adjustable valve in this invention can be a valve from the prior art, for example... Figures 4-5 The valve shown has a valve core with multiple valve discs. It is connected to the push rod 2221 via a transmission component consisting of a gear, connecting rod, and gear at point A, which controls the adjustable valve to switch between the open and closed states.

[0045] Specifically, when the sealing piston 222 is pushed toward the top of the air pipe 221, the opening of the adjustable valve increases, increasing the amount of cooling medium injected; when the sealing piston 222 is pulled back toward the bottom of the air pipe 221, the opening of the adjustable valve decreases, reducing the amount of cooling medium injected.

[0046] In a preferred embodiment of this utility model, such as Figure 3 As shown, the sealing piston 222 includes:

[0047] A pusher plate 2222 is provided with a mounting post 2223 on the side of the pusher plate 2222 facing the bottom of the air tube 221, and a push rod 2221 is provided on the side of the pusher plate 2222 facing the top of the air tube 221.

[0048] Sealing ring 2224 is fitted onto mounting post 2223.

[0049] In a preferred embodiment of the present invention, the sealing ring 2224 is provided with a first vent hole 2225, and the push plate 2222 is provided with a corresponding second vent hole 2226.

[0050] Specifically, in this embodiment, in order to form a sealed and air-filled air chamber 223 as described in the above embodiment, a sealing rubber ring 2224 is provided in the sealing piston 222;

[0051] During the assembly of the injection controller 22, the sealing piston 222 needs to be pushed into the air pipe 221. However, due to atmospheric pressure, it cannot be pushed in, and thus a pre-defined air chamber cannot be formed (the volume of the air chamber 221 can be determined by drawing scale lines on the wall of the air pipe 221). Therefore, a first exhaust hole 2225 is provided on the sealing ring 2224, and a corresponding second exhaust hole 2226 is provided on the pusher plate 2222. During the pushing process, the first exhaust hole 2225 and the second exhaust hole 2226 are aligned, and the sealing piston 222 can be pushed into the air pipe 221 smoothly. When it reaches the scale line, the pusher plate 2222 is rotated to make the first exhaust hole 2225 and the second exhaust hole 2226 misaligned, and the assembly of the injection controller 22 is completed.

[0052] In a preferred embodiment of the present invention, an atomizing nozzle is installed on the spray port 21.

[0053] Specifically, in this embodiment, the fine water droplets sprayed by the atomizing nozzle have a small diameter, generally at the micrometer level. They are extremely fine and easily absorb heat from the air, thereby achieving a rapid cooling effect.

[0054] In a preferred embodiment of the present invention, the cooling circulation pipe 1 is filled with a cooling circulation medium, which is cooling water or cooling inert gas.

[0055] Specifically, in this embodiment, both cooling water and inert gas are common cooling media, readily available and relatively inexpensive. This makes this invention highly applicable in various application scenarios. The inert gas does not chemically react with activated carbon or components in the exhaust gas, ensuring system safety. In applications requiring rapid cooling, cooling water may be more suitable; while in environments where chemical reactions or corrosion must be avoided, cooling inert gas may be safer.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present utility model.
