DETAILED DESCRIPTION

[0014] The application will be further described in detail below in conjunction with the drawings and specific embodiments, but is not limited to this, and any improvement or replacement in the basic spirit of the embodiment of the application still belongs to the range of the application to be protected.

[0015] As Figure 1 Indicated, the utility model provides a kind of safe adsorption device, including casing 1, the casing 1 one end is provided with air inlet 11, the other end is provided with gas outlet 12, the casing 1 is provided with several activated carbon adsorption plate 2, and the activated carbon adsorption plate 2 separates the space in casing 1 into several purification chambers 13;The casing 1 is provided with coil pipe 3 for cooling, and the coil pipe 3 has water inlet 31 and water outlet 32, and the water outlet 32 one end of the coil pipe 3 is also provided with branch pipe 33, and the branch pipe 33 is connected with spray pipe 4, and the spray pipe 4 is arranged in the purification chamber 13, and the spray pipe 4 is provided with several spray heads 41;The water inlet 31 is provided with first solenoid valve 34, and the water outlet 32 is provided with second solenoid valve 35, and the branch pipe 33 is provided with third solenoid valve 36.

[0016] When the desorption of activated carbon is carried out, the high-temperature gas is introduced into the gas outlet 12 of the shell 1, and the inlet gas is discharged from the gas inlet 11, which is opposite to the gas flow direction of the gas purification of the adsorption device. When the temperature in the shell 1 exceeds the set value, the first electromagnetic valve 34 and the second electromagnetic valve 35 are opened, and the third electromagnetic valve 36 is closed. The cooling water is introduced into the coil 3 in the shell 1 through the water inlet 31, and the nozzle 41 does not spray water. Through the heat conduction of the coil 3, the temperature in the shell 1 is lowered, and the temperature in the shell 1 is controlled within the predetermined value range. The water inlet 31 and the water outlet 32 can be communicated with the cooling tower to form a circulating water path, and the heat is dissipated. When the cooling effect of the coil 3 is insufficient to lower the temperature in the shell 1 to the predetermined value range, the third electromagnetic valve 36 is opened, the second electromagnetic valve 35 is closed, and the cooling water is introduced into the spray pipe 4. At this time, the coil 3 still plays a cooling role, and the nozzle 41 sprays water on the purification chamber 13, thereby directly cooling and wetting the activated carbon adsorption plate 2, preventing the activated carbon adsorption plate 2 from being too high to cause self-ignition. If the activated carbon adsorption plate 2 has self-ignition, the water sprayed by the nozzle 41 can also extinguish it. The scheme of the utility model can determine whether to open the spray pipe 4 for spraying and cooling according to actual needs. If the cooling effect of the coil 3 is sufficient to control the temperature rise in the shell 1, spraying is not needed, and the negative effects of spraying on the activated carbon adsorption plate 2 can be avoided.

[0017] In order to facilitate the installation of the coil 3, in some embodiments, the coil 3 is spirally arranged on the inner wall of the shell 1. The coil 3 is arranged in a spiral shape, which increases the length of the coil 3, that is, increases the heat exchange area, which is beneficial to rapid heat exchange with the heat in the shell 1.

[0018] Specifically, since the high-temperature gas enters the shell 1 through the gas outlet 12 during desorption, in some embodiments, the water inlet 31 of the coil 3 is arranged close to the gas outlet 12, and the water outlet 32 of the coil 3 is arranged close to the gas inlet 11. The temperature of the cooling water introduced into the water inlet 31 is the lowest, which can directly exchange heat with the high-temperature gas at the gas outlet 12 to reduce the temperature of the high-temperature gas entering the purification chamber 13.

[0019] In order to facilitate the introduction of cooling water into the plurality of spray pipes 4, in some embodiments, the branch pipe 33 is connected with the distribution pipe 5, and the distribution pipe 5 is connected with a plurality of spray pipes 4. Such a structure of the distribution pipe 5 can distribute the cooling water to each spray pipe 4, and the spray pipes 4 are in parallel connection.

[0020] In order to observe the temperature in the shell 1, in some embodiments, a temperature sensor 6 is arranged in the shell 1, and the temperature sensor 6 is arranged close to the air inlet 11. According to the temperature detected by the temperature sensor 6, the on-off of the first electromagnetic valve 34, the second electromagnetic valve 35 and the third electromagnetic valve 36 can be controlled by manual or automatic system to realize different cooling operations.

[0021] In order to avoid the occurrence of local high temperature and spontaneous combustion, in some embodiments, a spray pipe 4 is arranged in each of the purification chambers 13.

[0022] In order to facilitate the installation, replacement and maintenance of the coil 3, the spray pipe 4 and the activated carbon adsorption plate 2 in the shell 1, in some embodiments, a manhole is arranged on the top of the shell 1, and a discharge port (not shown in the figure) is arranged on the bottom of the shell 1. The arrangement of the manhole facilitates the installation, replacement and maintenance of the coil 3, the spray pipe 4 and the activated carbon adsorption plate 2 by the operator, and the arrangement of the discharge port can clean and discharge the deposits accumulated in the shell 1 in time, so as to prevent the influence on the adsorption effect.

[0023] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application. It should be understood that the above description is only for specific embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
