The guide collecting pipe is connected with a waste collecting port 4111 of the multi-stage air outlet filter assembly 4, and an outlet solenoid valve 61 is also installed on the guide collecting pipe.
When the multistage air outlet filter assembly 4 performs multistage filtration on the passing ammonia tail gas, the multistage air outlet filter assembly 4 can effectively filter sodium carbonate particles in the ammonia tail gas, the filtered sodium carbonate particles can fall into the guide collection pipeline from the waste collection port 4111, when the sodium carbonate particles in the guide collection pipeline need to be cleaned, a worker can open the electromagnetic valve 61, and after the electromagnetic valve 61 is opened, the sodium carbonate particles can be discharged to a region to be treated along the sodium carbonate particles.
The specific working principle is as follows:
The ammonia tail gas can be produced during production, ammonia tail gas purifying equipment pumps circulating ammonia tail gas through the circulating pipeline 1, the air inlet end of the circulating pipeline 1 is connected with a pumping area, staff installs the distributing pipeline 2 at the air conveying end of the circulating pipeline 1, the circulating pipeline 1 is used for distributing and guiding the ammonia tail gas, the ammonia tail gas in the pumping area can circulate to a plurality of reciprocating pushing and pressing air inlet mechanisms 3, when the circulating pipeline 1 needs circulating the ammonia tail gas, the reciprocating pushing and pressing air inlet mechanisms 3 are driven to synchronously rotate through the synchronous driving device 5, pumping work and extrusion work can be continuously formed when the reciprocating pushing and pressing air inlet mechanisms 3 rotate, the reciprocating pushing and pressing air inlet mechanisms 3 pump work and can suck the ammonia tail gas between the reciprocating pushing and pressing air inlet mechanisms 3 and the multistage air outlet filtering assemblies 4, then the reciprocating pushing and pressing air inlet mechanisms 3 and the multistage air outlet filtering assemblies 4 can extrude the ammonia tail gas, the ammonia tail gas can pass through the multistage air outlet filtering assemblies 4 and enter the ammonia tail gas purifying equipment, the multistage air outlet filtering assemblies 4 can filter the ammonia tail gas to effectively prevent the ammonia tail gas from entering the pure alkali particles inside the pure ammonia tail gas purifying equipment. The ammonia tail gas can be effectively filtered through the multistage filtering gas transmission device to improve the purity of the ammonia tail gas, and meanwhile, the gas circulation speed is ensured.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
