The ammonium carbamate energy recovery device comprises a CO2 stripping tower and a low-pressure decomposing tower, a high-pressure ammonium carbamate solution pipe is connected with an energy recovery device, and both the CO2 stripping tower and the low-pressure decomposing tower are connected with the energy recovery device through a pipeline. Compared with the prior art, the ammonium carbamate solution energy recovery device for the CO2 stripping tower has the characteristics of reasonable design, stable work, low production cost and the like, thereby effectively saving energy consumption and equipment cost, and improving the production efficiency.
Description
Technical field
The utility model relates to CO
2The stripping urea apparatus field, specifically a kind of CO2 stripper first ammonium liquid energy retracting device.
Background technology
Present China existing C O
2Stripping urea device, device capability mostly are more than 300,000 tons/year, and domestic largest device ability reaches 850,000 tons/year.Urea liquid after the technical process height is pressed into is through CO
2Pressure is 14.0MPa behind the stripping, the high pressure first ammonium liquid of domestic existing introduction or the outlet of homemade urea plant stripper is reduced to the laggard low pressure decomposing system of 0.3MPa through decompression valve with pressure, the pressure of high pressure first ammonium liquid can just waste, and it is very high to the quality requirement of decompression valve, need imported valve, increased production cost greatly.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of reasonable in design, stable working, a kind of CO that production cost is low are provided
2Stripper first ammonium liquid energy retracting device.
The technical scheme that its technical problem that solves the utility model adopts is: this energy recycle device comprises CO
2Stripper and low pressure decomposition tower, high pressure first ammonium liquid pipe is connected CO with recuperator
2Stripper is connected with recuperator by pipeline respectively with the low pressure decomposition tower.
Described low pressure decomposition tower is connected by the entrance point of pipeline with the low pressure carbamate condenser, the port of export of low pressure carbamate condenser is by the entrance point of pipeline connection low pressure carbamate condenser level tank, and the port of export of low pressure carbamate condenser level tank is connected with recuperator by pipeline.
A kind of CO of the present utility model
2Stripper first ammonium liquid energy retracting device is compared with prior art, has following characteristics: 1) to producing 300000 tons of CO per year
2Stripping urea device, the pressure that comes out from stripper are that the high pressure first ammonium liquid of 14.0MPa is 75m
3/ h, the density of first ammonium liquid is 1040kg/m
3, the efficient of energy recycle device is about 76 ~ 80%, 158.4 ten thousand kwh that then can economize on electricity every year, 564 tons in signature coal; 2) saved the high pressure relief control valve, made the low-pressure system operation more steady; 3) energy recycle device has substituted high pressure carbamate pump, has reduced equipment cost.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of CO of the present utility model
2Stripper first ammonium liquid energy retracting device, its structure comprises CO
2Stripper 1 and low pressure decomposition tower 2, high pressure first ammonium liquid pipe 6 is connected CO with recuperator 5
2Stripper 1 is connected with recuperator 5 by pipeline respectively with low pressure decomposition tower 2; Low pressure decomposition tower 2 is connected by the entrance point of pipeline with low pressure carbamate condenser 3, the port of export of low pressure carbamate condenser 3 is by the entrance point of pipeline connection low pressure carbamate condenser level tank 4, and the port of export of low pressure carbamate condenser level tank 4 is connected with recuperator 5 by pipeline.
Technological principle: from CO
2The pressure that stripper 1 comes out is that the high pressure first ammonium liquid of 14.0MPa enters recuperator 5, has reclaimed pressure that the pressure of high pressure first ammonium liquid can back first ammonium liquid and has reduced to 0.4MPa and directly enter low pressure decomposition tower 2; Recuperator 5 reclaimed high pressure first ammonium liquid pressure can after the pressure that is used for driving by low pressure carbamate condenser level tank 4 be 0.3MPa low pressure first ammonium liquid, make it to enter high-pressure system after pressure rises to 16.0MPa, this recuperator 5 can be complementary with the selected high pressure carbamate pump of urea plant, is hydraulic turbine or piston type.
A kind of CO of the present utility model
2Its processing and fabricating of stripper first ammonium liquid energy retracting device is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
