[0001] The utility model relates to the technical field of catalytic combustion equipment, in particular to organic waste gas catalytic combustion equipment. Background Art

[0002] In the existing technology, the organic waste gas generated by industrial enterprises in daily production and processing is likely to cause harm to the environment and have a harmful effect on human health. The combustion method is usually used to purify the organic waste gas. The organic waste gas is added to the catalytic combustion equipment and the waste gas is catalytically burned.

[0003] In commercially available catalytic combustion equipment for organic waste gas, the adsorption plates in the adsorption chamber become saturated after a period of use, requiring desorption before continued use. Existing technology cannot promptly monitor the adsorption status of the adsorption plates. Failure to promptly replace or desorb the plates after saturation results in harmful substances in the exhaust gas not being adsorbed, impacting treatment effectiveness. To address this issue, we propose a catalytic combustion equipment for organic waste gas. Utility Model Content

[0004] The purpose of the utility model is to provide a catalytic combustion device for organic waste gas, which has the advantage of using a weighing sensor to monitor the state of the adsorption plate, solving the problem that the existing technology cannot obtain the adsorption state of the adsorption plate in time.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 and 2 As shown, a catalytic combustion device for organic waste gas includes an activated carbon adsorption box 1 and a combustion chamber. The activated carbon adsorption box 1 is provided with an adsorption inlet 2 and an adsorption outlet 3. An adsorption plate is provided in the activated carbon adsorption box 1 between the adsorption inlet 2 and the adsorption outlet 3. The adsorption plate is placed on a support block on the inner wall of the activated carbon adsorption box 1. A weighing sensor is provided between the support block and the adsorption plate. The weighing sensor is used to monitor the weight change of the adsorption plate and obtain information on whether the adsorption plate is saturated with adsorption. Since the weight of the adsorption plate increases after adsorbing harmful substances in the exhaust gas, when the adsorption plate is saturated, it no longer adsorbs. The weighing sensor can monitor the weight change of the adsorption plate. When the weight of the adsorption plate reaches the maximum value, it indicates that the adsorption is saturated and needs to be replaced or desorbed.

[0025] like Figure 2As shown, the activated carbon adsorption box 1 is provided with a desorption inlet 4 and a desorption outlet 5, the adsorption inlet 2 is provided with a first air inlet valve 15, the adsorption outlet 3 is provided with a first air outlet valve 16, the desorption inlet 4 is provided with a second air inlet valve 17, and the desorption outlet 5 is provided with a second air outlet valve 18; by providing the desorption inlet 4 and the desorption outlet 5, desorption gas or high-temperature air can be directly introduced to achieve desorption without disassembling and replacing the adsorption plate.

[0026] The activated carbon adsorption box 1 is equipped with a controller 19, which is used to control the opening and closing of the first air inlet valve 15, the first air outlet valve 16, the second air inlet valve 17, and the second air outlet valve 18. By providing multiple air inlet and outlet valves, the adsorption inlet 2 and adsorption outlet 3 can be opened when adsorbing harmful exhaust gas substances, and the desorption inlet 4 and desorption outlet 5 can be closed. When desorption is required, the desorption inlet 4 and desorption outlet 5 are opened, and the adsorption inlet 2 and adsorption outlet 3 are closed.

[0027] like Figure 3 As shown, a booster pump 21 is provided on the desorption outlet 5, and the booster pump 21 is used to extract the desorbed exhaust gas in the activated carbon adsorption box 1. The booster pump 21 can drive the gas flow, facilitating the high-temperature air or desorbed gas to pass through the adsorption plate for desorption.

[0028] The controller 19 is equipped with a timer 20 for recording the desorption time. The timer 20 is designed to record the desorption time. When the load cell detects that the weight of the adsorption plate has stopped decreasing during the desorption process, after a certain period of time, desorption is complete. Adsorption time can also be monitored. If the weight of the adsorption plate stops increasing after a certain period of time during the adsorption process, it indicates that the adsorption plate is saturated. Alternatively, the maximum and minimum weights of the adsorption plate can be used to determine the completion of desorption and the saturation of the adsorption plate.

[0029] like Figure 4 As shown, a heating jacket 22 is provided on the desorption inlet 4, and the heating jacket 22 can heat the gas entering the activated carbon adsorption box 1 through the desorption inlet 4. The adsorption plate can achieve desorption under high-temperature gas.

[0030] The activated carbon adsorption box 1 is provided with a temperature sensor 26, which can monitor the temperature inside the activated carbon adsorption box 1. The controller 19 controls the operation of the heating jacket 22 according to the data monitored by the temperature sensor 26 to prevent the temperature of the adsorption plate from being too high or too low.

[0031] The desorption inlet 4 is provided with a cooling jacket 23, which is connected to the water tank 24 through a water pipe, and a water pump 25 is provided on the water pipe. The cooling jacket 23 can reduce the intake air temperature of the desorption inlet 4, thereby cooling the desorption plate to avoid safety accidents caused by combustion of the adsorption plate due to excessive temperature.

[0032] The adsorption plate includes a first adsorption plate 6, a second adsorption plate 7 and a third adsorption plate 8 arranged from top to bottom. The first adsorption plate 6 is supported by a first support block 9, the second adsorption plate 7 is supported by a second support block 10, and the third adsorption plate 8 is supported by a third support block 11. The weighing sensor includes a first weighing sensor 12, a second weighing sensor 13 and a third weighing sensor 14. The first weighing sensor 12 is arranged between the first adsorption plate 6 and the first support block 9, the second weighing sensor 13 is arranged between the second adsorption plate 7 and the second support block 10, and the third weighing sensor 14 is arranged between the third adsorption plate 8 and the third support block 11. By setting up multiple adsorption plates, the adsorption capacity can be improved. When any adsorption plate is saturated, it can be identified by the weighing sensor and desorbed.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
