The improved ammonia gas recovery system is reasonable in design and simple in structure; when the water level of the lower-stage circulating water tank is low, the lower-stage digital display liquidometer can detect the information and transmits the information to the lower-stage controller, the controller controls the upper-stage three-way valve to enable water flow to be switched over and flow to the lower-stage circulating water tank, so that the water level of the lower-stage circulating water tank is supplemented.
Description
Technical field
The utility model relates to gas recovery system field, refers to specifically a kind of improved Ammonia recovery system.
Background technology
Ammonia is the compound of nitrogen and hydrogen, is the major product of ammonia synthesizing industry and the byproduct of coking industry, can burn people's the mucous membrane of skin, eyes and respiratory apparatus of ammonia, once hyperabsorption can cause lung swelling, so that dead.And ammonia is raw material important in Chemical Manufacture, directly enter sky atmosphere and air and people are polluted, endangered for fear of the ammonia of producing in tail gas, in existing Chemical Manufacture, all to adopt a cover system to reclaim ammonia.
Existing Ammonia recovery system is mainly to adopt the technology that absorbs embrane method, this technology is now give up leading in Ammonia recovery technology, energy-saving and environmental protection and most effective technology, its cardinal principle is that useless ammonia is together in series by multistage absorption device after cooling again, reclaims useless ammonia to certain density ammoniacal liquor to reach.Every grade of absorption plant includes a film absorption group, a cyclic water tank and a circulating pump, and this circulating pump is squeezed into film absorption group by the pure water in cyclic water tank and absorbed the ammonia in waste gas.Return owing to can being equipped with one at the cyclic water tank of upper level absorption plant in prior art the liquid level that liquid pump supplements the cyclic water tank of next stage absorption plant, but this technology control ratio is more loaded down with trivial details, and operation energy consumption and the costs that increase by one time liquid pump again, design is rationally little more.
Utility model content
The utility model provides a kind of improved Ammonia recovery system, and its main purpose is to overcome available technology adopting and returns liquid pump the liquid level of next stage cyclic water tank is supplemented, and cause that control ratio is more loaded down with trivial details, problem that operation energy consumption and cost increase.
In order to solve above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of improved Ammonia recovery system, comprise the multistage absorption plant being communicated with successively, every grade of absorption plant includes the cyclic water tank, circulating pump and the absorbing film group that are communicated with successively, every grade of described absorption plant also comprises digital display liquid-level gauge, controller and electric T-shaped valve, described digital display liquid-level gauge is located on cyclic water tank and with controller and is connected, described electric T-shaped valve is located between circulating pump and absorbing film group and with the controller of next stage absorption plant and is connected, and this electric T-shaped valve is communicated with the cyclic water tank of circulating pump, absorbing film group and next stage absorption plant respectively.
Further, described controller is PLC controller.
Further, described absorption plant is provided with Pyatyi.
Further, the bottom of described cyclic water tank is provided with drain valve.
From above-mentioned to description of the present utility model, compared to the prior art, the utlity model has following advantage: the utility model is reasonable in design, simple in structure, when the water level of the cyclic water tank of next stage absorption plant is during in low liquid level, the digital display liquid-level gauge of next stage absorption plant can detect this information, and this information is passed to the controller of next stage absorption plant, this controller is controlled the cyclic water tank of the triple valve switching flow direction next stage absorption plant of upper level absorption plant again, supplements thereby the cyclic water tank of next stage absorption plant is carried out to liquid level.Than existing technology, adopt the utility model to make system control more simple, stable, and operation energy consumption and cost lower.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model absorption plant.
Detailed description of the invention
See figures.1.and.2.A kind of improved Ammonia recovery system, comprises the absorption plant that Pyatyi is communicated with successively, and this Pyatyi absorption plant is respectively first order absorption plant 1, second level absorption plant 2, third level absorption plant 3, fourth stage absorption plant 4 and level V absorption plant 5.Described first order absorption plant 1, second level absorption plant 2, third level absorption plant 3, fourth stage absorption plant 4 and level V absorption plant 5 include cyclic water tank 11, circulating pump 12, absorbing film group 13, digital display liquid-level gauge 14, PLC controller 15 and electric T-shaped valve 16.Described cyclic water tank 11, circulating pump 12 and absorbing film group 13 are communicated with successively, described digital display liquid-level gauge 14 is located on cyclic water tank 11 and with PLC controller 15 and is connected, described electric T-shaped valve 16 is located between circulating pump 12 and absorbing film group 13 and with the PLC controller 15 of next stage absorption plant and is connected, and this electric T-shaped valve 16 is communicated with the cyclic water tank 11 of circulating pump 12, absorbing film group 13 and next stage absorption plant respectively.The bottom of described cyclic water tank 11 is provided with drain valve 6, and this drain valve 6 cleans for the discharge of cyclic water tank 11.
See figures.1.and.2.Taking the work relationship between first order absorption plant 1 and second level absorption plant 2 as example: the electric T-shaped valve 16 of described first order absorption plant 1 is connected with the PLC controller 15 of second level absorption plant 2, this electric T-shaped valve 16 is located between the circulating pump 12 and absorbing film group 13 of first order absorption plant 1, and is communicated with the cyclic water tank 11 of circulating pump 12, absorbing film group 13 and second level absorption plant 2 respectively.When the water level of the cyclic water tank 11 of second level absorption plant 2 is during in low liquid level, the digital display liquid-level gauge 14 of second level absorption plant 2 can detect this information, and this information is passed to the PLC controller 15 of second level absorption plant 2, the cyclic water tank 11 that the triple valve 16 that the PLC controller 15 of this second level absorption plant 2 is controlled first order absorption plant 1 again switches flow direction second level absorption plant 2 carries out supplementing of water level.
