Abstract
The utility model provides a safe and environment-protection recycling device for ammonia exhaust gas by a negative pressure method, which consists of a jet injector, a cooler, an ammonia water negative pressure tank and a circular pump. The negative pressure which is generated by the recycling device absorbs the ammonia exhaust gas and dissolves the ammonia exhaust gas in the water, thereby effectively solving the troublesome problem in the existing ammonia exhaust gas recycling and handling process, completely preventing the environmental pollution caused by the ammonia exhaust gas, and thus achieving the aim of safely recycling the ammonia exhaust gas.
Description
Technical field
The utility model relates to a kind of safety environmentally friendly ammonia tail gas recovering device, and especially a kind of water jet that utilizes sprays the generation negative pressure principle, realizes that safety and environmental protection reclaims the device of ammonia tail gas.
Background technique
Liquefied ammonia is protected operation as production, packing and the use liquefied ammonia of liquefied ammonia in production and using process, usually need to carry out exhaust emissions, or occur inevitably revealing.At present, there are two kinds to what the processing method of tail gas was used always, the one, adopt the Large Storage Tanks gas tank to collect tail gas, with compressor the ammonia that reclaims is compressed into liquefied ammonia then, so that utilize again, its shortcoming is that equipment investment is big, the energy consumption height, input and output are lower, and owing to be positive pressure operation, leak easily; The 2nd, ammonia tail gas is discharged, ammonia tail gas can be concentrated, carry out high altitude discharge with high chimney, also can be not add processing, let alone discharging, its shortcoming is not only to cause the wasting of resources and befouling environment.
Summary of the invention
The purpose of this utility model is to design a kind of negative pressure method safety environmentally friendly ammonia tail gas recovering device; the negative pressure of utilizing this device to produce sucks ammonia tail gas; and it is dissolved in the water; reclaim the thorny problem that exists in the governance process to solve at present positive platen press ammonia tail gas; thoroughly eliminate the environmental pollution that ammonia tail gas brings, reach the purpose that safety environmentally friendly ammonia tail gas reclaims.
The technological scheme that its technical problem that solves the utility model adopts is: the recovering device that design one cover is made up of jet ejectors, cooler, ammoniacal liquor negative-pressure cup and recycle pump, and wherein jet ejectors, cooler, ammoniacal liquor negative-pressure cup, recycle pump are in turn connected into circulation loop by pipeline; Jet ejectors is equipped with aspirating air pipe by suction valve; Water-adding pipe is equipped with by water-feeding valve in ammoniacal liquor negative-pressure cup top, and probe tube is equipped with by sampling cock in the bottom; On the connecting tube of recycle pump and ammoniacal liquor negative-pressure cup inlet valve is housed, threeway is housed on the outlet conduit, an end is connected by the inlet of outlet valve with the jet injection pump, and the other end is equipped with filling exit by filling valve.When this device is in when stopping state, open the water-feeding valve water-filling at ammoniacal liquor negative-pressure cup top, close whole valves then.When needs reclaim ammonia tail gas, open inlet valve and outlet valve on the recycle pump, the ON cycle pump, at this moment, recycle pump is constantly delivered to jet ejectors with the water in the ammoniacal liquor negative-pressure cup, produces negative pressure by jet ejectors.The outlet conduit of ammonia tail gas is connected with the aspirating air pipe of jet ejectors, open the suction valve on the jet ejectors after, negative pressure that ammonia tail gas is constantly produced sucks, and is dissolved in the water, and after the cooler cooling, flows back in the ammoniacal liquor negative-pressure cup.Behind end-of-job, close all valves.Open the sampling cock sample analysis ammonia concn of ammoniacal liquor negative-pressure cup, when ammonia concn reaches 30-40%, be finished product ammoniacal liquor.Utilize recycle pump to carry out finished product ammoniacal liquor canned.
The negative pressure method safety environmentally friendly ammonia tail gas recovering device that the utility model provides reclaims liquefied ammonia tail gas fully, and leakage problem is also solved up hill and dale, has promptly protected workers'health, has guaranteed safety in production, has stopped the pollution of ammonia to environment again effectively; And technology is simple, and is easy to operate, little investment, high efficiency.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
