The filter layer can further filter out solid matters such as dust particles in the gas, and the first protective layer and the second protective layer can protect the first porous baffle 43 and the second porous baffle 44 from being directly touched or bumped by the drying agent 45, so that the drying agent 45 is crushed and falls off or even gaps of the porous baffles are blocked, and the like.

In one embodiment of the present utility model, the cylinder structure of the dryer 4 may include a cylinder and a cylinder cover, and the cylinder cover may be fixed by flange connection, so that the first porous baffle 43, the second porous baffle 44, the filter layer, the first protection layer, the second protection layer, the drying agent 45, etc. inside the dryer may be more conveniently replaced or cleaned.

In one embodiment of the present utility model, the desiccant 45 is a spherical desiccant 45, more preferably an alkaline desiccant 45, such as alumina balls, to dry the exhaust gas while further ensuring that the exhaust gas is free of acid gases.

In one embodiment of the utility model, the integral continuous treatment device for removing dust and explosion-proof acid gas is in a skid-mounted structure, is convenient for industrial maintenance, disassembly and replacement of related parts, and more preferably, each part can be matched with a supporting piece for supporting the device or the corresponding part under the condition of need.

The utility model provides an integrated continuous treatment device for removing dust and explosion-proof acid gas, which has the working principle that: the alkali liquor in the alkali liquor storage tank 1 is input into the liquid tank absorber 2 through a pipeline and is subjected to mixed reaction with the waste gas entering the liquid tank absorber 2 through an air inlet, so that the acid gas contained in the waste gas is subjected to neutralization absorption treatment, the mixed gas-liquid mixture is conveyed to the gas-liquid separation device 3 for gas-liquid separation, substances such as dust particles and the like in the waste gas can be further separated with the gas along with the liquid during separation, and the separated gas is conveyed to a subsequent dryer 4 through a pipeline for further drying treatment or is directly conveyed to a vacuum pump and other parts for further processing. Therefore, the phenomena that dust particles contained in the waste gas cause abrasion or blockage to parts such as a follow-up vacuum pump and the like, and acid gas contained in the waste gas causes corrosion damage to the parts such as the vacuum pump and the like are avoided, the service condition of the follow-up parts such as the vacuum pump is ensured, the service life of the follow-up parts is further prolonged, and the cost is reduced.

The above-described embodiments are only preferred embodiments of the present utility model, and are not intended to limit the utility model in any way, but other variations and modifications are possible without exceeding the technical solutions described in the claims.
