Abstract
The utility model discloses an ammonium bicarbonate producing device capable of safely recycling pressure swing adsorption decarbonization emptying air and belongs to ammonium bicarbonate producing devices. The ammonium bicarbonate producing device capable of safely recycling the pressure swing adsorption decarbonization emptying air comprises a pressure swing adsorption decarbonization device, a buffering tank, an emptying header pipe and a carbon dioxide compressor, wherein the pressure swing adsorption decarbonization device is connected with the emptying header pipe through a pipeline provided with a butterfly valve I and a butterfly valve II and is connected with the buffering tank through a pipeline provided with the butterfly valve I and a butterfly valve III; the buffering tank is connected with the carbon dioxide compressor through a pipeline provided with a butterfly valve IV; the emptying header pipe is further connected with the buffering tank through a pipeline provided with a butterfly valve V. The ammonium bicarbonate producing device is simple in structure, can be popularized on the basis of an existing device, and can thoroughly solve the problem that the carbon dioxide compressor during a running process cannot stably run for a long time because the pressure of an inlet is negative.
Description
Technical field
The utility model belongs to carbon ammonium production equipment, is specifically related to a kind of safety and reclaims the carbon ammonium process units that pressure swing adsorption decarbonization is dropped a hint.
Background technology
The decarbonization method that at present domestic and international synthesis ammonia plant adopts can be divided into wet method and dry method two big classes, wherein to continue to use history longer for wet method, and dry method (pressure swing adsorption method) is the power-saving technology of Recent study and exploitation, has degree of purification height, flow process is simple, energy consumption is low, cost is low advantage.
The recovering state of melamine tail gas is one of key that influences Melamine Production enterprise overall efficiency.At present low-pressure process melamine tail gas processing method mainly contains ammonia carbon and separates 3 kinds of liquefied ammonia processed and food-grade carbon-dioxide, coproduction urea and co-producing ammonium bicarbonates, and technology is maturation all.
Low-pressure process round-robin method melamine device commonly used, be the ammonia in the tail gas to be made the carbon dioxide that concentrated ammonia liquor is sent to during pressure swing adsorption decarbonization is dropped a hint in carbonization workshop section and the synthesis ammonia system produce the carbon ammonium, each valve is all opened in the time of the device even running, conversion gas is after the decarburization of pressure swing adsorption decarbonization device, most of carbon dioxide is through emptying house steward emptying, the small part carbon dioxide enters surge tank, produce the carbon ammonium through being sent to carbonization workshop section after the carbon-dioxide gas compressor pressurization, excess carbon dioxide is through emptying house steward emptying.Existing this retracting device shortcoming is most of through emptying house steward emptying for dropping a hint; form negative pressure in the surge tank jar easily; there is unsafe factor; the carbon-dioxide gas compressor fluctuation of service; occur easily shutting down suddenly; former because inlet pressure is designed to pressure-fired, and actual inlet pressure forms negative pressure easily.
Summary of the invention
The purpose of this utility model is that to solve carbon-dioxide gas compressor in service because inlet gas pressure becomes the problem that negative pressure can not operation steady in a long-term, thereby provides a kind of safety to reclaim the production carbon ammonium device that pressure swing adsorption decarbonization is dropped a hint.
The utility model is achieved through the following technical solutions: a kind of safety reclaims the carbon ammonium process units that pressure swing adsorption decarbonization is dropped a hint, comprise the pressure swing adsorption decarbonization device, surge tank, the emptying house steward, carbon-dioxide gas compressor, described pressure swing adsorption decarbonization device is by being provided with the butterfly valve I, the pipeline of butterfly valve II is connected with the emptying house steward, described pressure swing adsorption decarbonization device is by being provided with the butterfly valve I, the pipeline of butterfly valve III is connected with surge tank, described surge tank is connected with carbon-dioxide gas compressor by the pipeline that is provided with the butterfly valve IV, and described emptying house steward also is connected with surge tank by the pipeline that is provided with the butterfly valve V.
Further, described pressure swing adsorption decarbonization device is 27000NM
3/ h pressure swing adsorption decarbonization device, described surge tank are 60 cubes of surge tanks, and described carbon-dioxide gas compressor is DW-60/40 type carbon-dioxide gas compressor.
During the said apparatus even running, except the butterfly valve II was closed, other all butterfly valves were all opened, and conversion gas is through 27000NM
3After the decarburization of/h pressure swing adsorption decarbonization device, the carbon dioxide of dropping a hint all enters 60 cubes of surge tanks, all the time (reason: per hour emptying total amount is 6700 cubes to become pressure-fired in the surge tank, actual requirement is 3600 cubes), excess carbon dioxide is sent to emptying house steward emptying through the pipeline that the butterfly valve V is housed, and becomes 0.4MPa through DW-60/40 type carbon-dioxide gas compressor pressurization back pressure and is sent to carbonization workshop section production carbon ammonium.
The utility model is simple in structure, can improve popularization on the existing apparatus basis, can solve thoroughly that carbon-dioxide gas compressor is in service to become the problem that negative pressure can not operation steady in a long-term because of inlet gas pressure.
