[0002] Semiconductor, photovoltaic, optical fiber and other industries often use equipment with acidic and alkaline chemicals. During the maintenance of these equipment, some volatile acidic and alkaline gases will be generated. Acid mist and alkaline mist are highly corrosive and toxic. If not handled in time, the emission of acid mist and alkaline mist will cause acidic and alkaline gases to diffuse in the air of the workplace, and after being discharged into the atmosphere, it will cause acid and alkaline precipitation in the atmospheric environment. It not only endangers the health of workers and residents around the factory, corrodes factory equipment and precision instruments, causes losses in production and life, but also has adverse effects on the survival of crops and other animals and plants.

[0003] Relevant environmental laws and regulations stipulate that these volatile acidic and alkaline gases must be discharged in an organized and standard manner. Therefore, the exhaust gas from the equipment must be collected at designated locations and then specially treated before it can be discharged into the atmosphere. Summary of the invention

[0018] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0020] The present invention will be further described below in conjunction with specific embodiments, but this is not intended to limit the present invention.

[0021] like Figure 1 As shown, the exhaust gas treatment device provided in the embodiment of the utility model includes a movable mobile trolley 1 and a gas collecting hose 2, an adsorber 3, a connecting hose 4, and a fan 5 installed on the mobile trolley 1 and connected in sequence. The adsorber 3 is installed on the mobile trolley 1 in an adjustable manner at the top and bottom. The adsorber 3 is filled with a filler layer for adsorbing volatile gases (such volatile gases may include alkaline gases, acidic gases, or gases with pungent odors, etc., the emission of which may cause environmental atmospheric pollution).

[0022] In the present invention, when it is necessary to adsorb volatile gases, the rollers at the bottom of the mobile trolley 1 can be used to move the device to a corresponding location, and then the fan 5 can be started. When the fan 5 is started, the waste gas is sucked out from the equipment or environment that generates acid and alkali waste gas, enters from the bottom inlet of the adsorber 3, and the waste gas is adsorbed and reacted with the chemical filter material filled in the adsorber 3, and is sucked into the fan 5 from the top outlet of the adsorber 3, and the treated waste gas is discharged from the outlet of the fan 5.

[0023] As a specific description, the packing layer can be an alkaline chemical filter material for absorbing acidic gas and / or an acidic chemical filter material layer for absorbing alkaline gas. For example, when the adsorber 3 is used to adsorb volatile SO2, the packing layer can be a potassium hydroxide layer, and the reaction formula for adsorbing SO2 is:

[0024] 2KOH+SO2=K2SO3+H2O, KOH+SO2=KHSO3; when the adsorber 3 is used to adsorb volatile NH3, the packing layer can be a phosphoric acid layer, and the reaction formula for adsorbing NH3 is:

[0025] 3NH3+H3PO4=(NH4)3PO4, 2NH3+H3PO4=(NH4)2HPO4.

[0026] Furthermore, in the utility model, the filler layer may be further filled with a water absorbent, which may be aluminum oxide. Aluminum oxide has strong water absorption and can absorb moisture in the air to create a humid environment for chemical filter materials and volatile gases to accelerate the reaction, and can also adsorb water generated by the reaction.

[0027] Furthermore, in the utility model, the filler layer may be further filled with an adsorbent, and the adsorbent may be set to activated carbon. If a gas with a pungent odor is volatilized in the storage tank, the activated carbon may directly absorb it. If impurities are generated after the volatile gas reacts with the chemical filter material, the activated carbon may also adsorb them to prevent the impurities from falling into the storage tank.

[0028] In the utility model, a porous support for supporting the packing layer is provided in the adsorber 3, and the porous support can be provided as a perforated partition plate for stably placing the packing layer. A filter cotton is detachably provided on the porous support, and the filter cotton is made of polyester fiber non-woven fabric, which is corrosion-resistant and aging-resistant, and has isolation and reverse filtering functions, and can isolate the impurities generated after the reaction.

[0029] To facilitate the replacement of packing, Figure 1 As shown, the outlet end of the gas collecting hose 2 in the utility model is installed on the air inlet flange 9 at the bottom of the adsorber 3, and the air inlet end of the connecting hose 4 is installed on the air outlet flange 10 at the top of the adsorber 3, so as to facilitate the operator to quickly install and disassemble the adsorber 3.

[0030] In order to facilitate the replacement of adsorbers with filling layers of different heights according to gas concentration, such as Figure 1 As shown, in the utility model, 4 or 5 adjusting rods 6 are installed at intervals along the circumferential direction of the adsorber 3 at the outlet end, and 4 or 5 fixing rods 7 corresponding to the adjusting rods 6 are installed vertically on the mobile trolley 1. The adjusting rods 6 are provided with fixing holes (not shown in the figure), and the fixing rods 7 are provided with multiple adjusting holes 8 spaced apart at upper and lower intervals along the height direction of the fixing rods 7. The adsorber 3 is installed on the mobile trolley 1 by fastening bolts passing through the fixing holes and the corresponding adjusting holes 8. Under the above structure, after selecting an adsorber 3 with a filling layer of corresponding height according to the exhaust gas concentration, the adsorber 3 can be adjusted to a suitable height first to avoid a decrease in adsorption efficiency due to the bending of the gas collecting hose 2 and a low stability of the device due to the excessive center of gravity of the device caused by the adsorber 3, and then the adsorber 3 is fixed to the mobile trolley 1 by bolts. The vertically placed adsorber 3 in the utility model makes the overall footprint of the device small, and is also convenient for the entry and exit and use of the device in a narrow environment.

[0031] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of the present invention specification should be included in the protection scope of the present invention.
