Abstract
The utility model provides a novel main condensing evaporator. The novel main condensing evaporator can not only guarantee equipment safety, but also eliminate the tower inlet degree of superheat of expanded air. The novel main condensing evaporator comprises a shell provided with a nitrogen inlet, a liquid nitrogen outlet, an expanded air inlet and an expanded air outlet; a main expanded air cooling board arranged in the shell is provided with a plurality of nitrogen channels, liquid oxygen channels and expanded air channels; the expanded air channels are connected with the expanded air inlet and the expanded air outlet respectively; the nitrogen channels are connected with the nitrogen inlet and the liquid nitrogen outlet respectively. According to the novel main condensing evaporator, the expanded air channels are added to the main expanded air cooling board of the deep cooling air separation condensing evaporator so that the expanded air can pass through part of main cooling channels, the degree of supercooling of the expanded air is decreased, and the air separation effect of a thermosyphon evaporator is achieved.
Description
Technical field
The utility model relates to a kind of evaporimeter, especially a kind of main condenser evaporimeter.
Background technology
The 4th generation molecular sieve adsorption flow process cryogenic air separation unit in, there are two kinds of flow processs, a kind of thermal siphon evaporimeter that adds, a kind of thermal siphon evaporimeter that do not add.The reason that adds thermal siphon evaporimeter has the degree of supercooling that can reduce expanded air, the tower column plate number of plies in minimizing.And the self-loopa of supercharging liquid oxygen, improve main cold safety.A period of time is found recently, and thermal siphon evaporimeter uses, and the unreasonable dry blowing district that forms in thermal siphon due to structure, very easily causes the microexplosion of thermal siphon evaporimeter, causes ice chest distortion, stop, and the major break down of even main cold blast.So present flow process is all in the use that reduces thermal siphon evaporimeter.In full immersed type condenser/evaporator, liquid oxygen forms liquid oxygen self-loopa in plate type heat exchanger, prevents that dry blowing from appearring in main cooling plate type, has effectively prevented hydrocarbon gathering, has guaranteed main cold safety.In molecular sieve preliminary clearning technique, owing to having removed liquid oxygen adsorber, the liquid oxygen cycling rate that thermal siphon evaporimeter provides is much smaller than main cold, and it has little significance to device security protective action, but elimination expanded air is entered to the upper tower degree of superheat, is still highly profitable.
Utility model content
The purpose of this utility model is to provide a kind ofly can guarantee device security, can eliminate the Novel main condenser/evaporator that expanded air enters the upper tower degree of superheat again.
The Novel main condenser/evaporator of realizing the utility model object, comprises housing, is provided with nitrogen inlet, liquid nitrogen outlet, expanded air import and expanded air outlet on described housing; In described housing, be provided with the main cold drawing of expanded air, on the main cold drawing of described expanded air, be respectively equipped with a plurality of channel of nitrogen, liquid oxygen passage and expanded air passage; Outlet is connected described expanded air passage with expanded air with expanded air import respectively; Outlet is connected described channel of nitrogen with liquid nitrogen with nitrogen inlet respectively.
Another Novel main condenser/evaporator of realizing the utility model object, comprises housing, is provided with nitrogen inlet, liquid nitrogen outlet, expanded air import and expanded air outlet on described housing; In described housing, be provided with main cold drawing and expanded air plate, described main cold drawing comprises a plurality of spaced channel of nitrogen and liquid oxygen passage, and described expanded air plate comprises a plurality of spaced expanded air passages and liquid oxygen passage; Respectively at nitrogen inlet, outlet is connected described channel of nitrogen with liquid nitrogen, and outlet is connected described expanded air passage with expanded air with expanded air import respectively.
The beneficial effects of the utility model are as follows: Novel main condenser/evaporator of the present utility model, on the main cold drawing of cryogenic air separation unit, condenser/evaporator, increase the passage of expanded air, make expanded air pass through the passage that part master is cold, reduce the degree of supercooling of expanded air, can reach the effect that the sky with thermal siphon evaporimeter divides, and with the sky of thermal siphon, do not divide and there is identical security.
Accompanying drawing explanation
Fig. 1 is the structural representation of Novel main condenser/evaporator of the present utility model.
Fig. 2 is the structural representation of another Novel main condenser/evaporator of the present utility model.
The specific embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, Novel main condenser/evaporator of the present utility model, comprises housing 1, is provided with nitrogen inlet 3, liquid nitrogen outlet 4, expanded air import 5 and expanded air outlet 6 on described housing 1; In described housing 1, be provided with the main cold drawing 2 of expanded air, on the main cold drawing 2 of described expanded air, be respectively equipped with a plurality of channel of nitrogen, liquid oxygen passage and expanded air passage; Described expanded air passage is connected with expanded air outlet 6 with expanded air import 5 respectively; Described channel of nitrogen is connected with liquid nitrogen outlet 4 with nitrogen inlet 3 respectively.
As shown in Figure 2, another Novel main condenser/evaporator of the present utility model, comprises housing 1, is provided with nitrogen inlet 3, liquid nitrogen outlet 4, expanded air import 5 and expanded air outlet 6 on described housing 1; In described housing 1, be provided with main cold drawing 7 and expanded air plate 8, described main cold drawing 7 comprises a plurality of spaced channel of nitrogen and liquid oxygen passage, and described expanded air plate 8 comprises a plurality of spaced expanded air passages and liquid oxygen passage; Described channel of nitrogen is connected with liquid nitrogen outlet 4 respectively at nitrogen inlet 3, and described expanded air passage is connected with expanded air outlet 6 with expanded air import 5 respectively.
The utility model increases the passage of expanded air on the main cold drawing of cryogenic air separation unit, condenser/evaporator, make expanded air pass through the passage that part master is cold, reduce the degree of supercooling of expanded air, can reach the effect that the sky with thermal siphon evaporimeter divides, with the sky of thermal siphon, divide and there is identical security simultaneously with not.
Embodiment recited above is described preferred embodiment of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
