Description
Technical field
This utility model relates to field of chemical equipment, is specifically related to a kind of cold end inner tube tube sheet and has the Ammonia United Chiller With of slipper seal structure.
Background technology
Ammonia United Chiller With is the Multifunctional heat exchange equipment of ammonia separation workshop section in ammonia synthesis system, it instead of I grade of ammonia cooler in the most traditional old process, II grade of ammonia cooler, cool exchanger, the ammonia convertor synthesis gas after waste heat recovery, cooling by water out can be made, in one equipment of Ammonia United Chiller With, realize multistage cooling, make ammonia component condense, and reclaim the cold of ammonia separator circulating air out.Use Ammonia United Chiller With can reduce the high pressure equipment number of units of ammonia synthesis system, high-pressure connecting pipe line between minimizing equipment, reduce floor space, reduce investment outlay, the resistance drop of system can also be reduced, reduce the power consumption in production process and cooling-water consumption, not only improve energy-saving and cost-reducing, achieve again and reduce the discharge of carbon dioxide because reducing power consumption.So, Ammonia United Chiller With is the alternate device of energy-saving and emission-reduction in ammonia synthesis system.
Ammonia United Chiller With is a Heat Exchangers, and tube side is high pressure, and heat exchanger tube is made up of concentric outer tube and inner tube, and the space in outer tube is divided into central passage radially and annular space passage two parts by inner tube.The shell side of Ammonia United Chiller With is ammonia vaporization chamber, in order to obtain relatively low synthesis gas chilling temperature, to make the ammonia component condensation as much as possible in synthesis gas and separating, typically ammonia vaporization chamber is divided into two or more independent evaporation cavities vertically, utilizes the different evaporating temperatures of liquefied ammonia to be cooled down step by step by synthesis gas.The tube side of Ammonia United Chiller With is by hot junction bobbin carriage, cold end bobbin carriage, and one group of heat exchanger tube of connection hot junction bobbin carriage and cold end bobbin carriage forms, hot junction bobbin carriage and cold end bobbin carriage are respectively arranged with one piece of inner tube tube sheet, space in bobbin carriage is divided into two chambeies by inner tube tube sheet, the outer tube of heat exchanger tube is connected with supervisor's plate of hot junction bobbin carriage and cold end bobbin carriage, inner tube is connected with the inner tube tube sheet in two bobbin carriages, and annular space channel lumens and the central passage chamber of inner tube tube sheet both sides are not connected.
The work process of Ammonia United Chiller With is: the synthesis gas come from water under high pressure cooler, the annular space channel lumens of the hot junction bobbin carriage on the left of entrance, the annular space passage of heat exchanger tube flow from left to right, is first cooled by the liquefied ammonia of ammonia vaporization chamber the first intracavity；The liquefied ammonia temperature of ammonia vaporization chamber the second intracavity is lower than the first chamber, and synthesis gas, through the position in the second chamber, is cooled by the liquefied ammonia of the second intracavity again.If ammonia vaporization chamber is separated into plural evaporation cavity, in ammonia vaporization chamber, the temperature of each intracavity liquefied ammonia reduces the most step by step, when synthesis gas arrives cold end bobbin carriage, temperature has been reduced to minimum, now, the ammonia component overwhelming majority cooling liquid in synthesis gas, then it is pooled to the annular space channel lumens of the cold end bobbin carriage on right side, synthesis gas containing liquefied ammonia leaves the annular space channel lumens of cold end bobbin carriage and enters ammonia separator, makes liquefied ammonia separate with gas.Separate the gas after liquefied ammonia and be referred to as circulating air, because the temperature of circulating air is the lowest, makes circulating air return to the central passage chamber of cold end bobbin carriage, central passage flow from right to left, for cooling down the synthesis gas in annular space passage, its objective is to reclaim the cold of circulating air.After last circulating air is pooled to the central passage chamber of hot junction bobbin carriage, sends into recycle gas compressor and return synthesizing section.
