Abstract
The utility model discloses a kind of liquid nitrogen off gas energy recovery device, including main body, pipeline, import, outlet and baffle plate, described import includes coolant import and liquid nitrogen import, Pipe installing is provided with baffle plate in body interior and pipeline, coolant import and liquid nitrogen import are positioned at the same side of main body, and outlet is positioned at the opposite side of main body.This apparatus structure is simple, and reasonable in design, detachability is good, it is simple to installs and changes；By using the pipeline of band baffle plate, liquid nitrogen tail gas retention time in the duct can be extended, thus the coolant in casing is fully lowered the temperature, reach neither to affect production cooling rate, again the cold of liquid nitrogen tail gas is made full use of thus reach energy-saving and cost-reducing purpose, improve the service efficiency of liquid nitrogen cold, using effect is good.
Description
Technical field
This utility model relates to a kind of retracting device, specifically a kind of liquid nitrogen off gas energy recovery device.
Background technology
Cefoxitin acid is a kind of medicine intermediate, is a kind of white powder, and cefoxitin acid is to make for antibacterial cefoxitin sodium and the important component part of cefoxitin.In the production process of cefoxitin acid, a large amount of use liquid nitrogen gasifications are as deep cooling low-temperature receiver, during the use of liquid nitrogen, requirement that cooling rate, so not all cold is used for producing cooling, most cold is the most in line causes energy waste in air, low to the utilization rate of liquid nitrogen cold, waste huge during reaching the target temperature of cooling the soonest, the cold of another part is directly accessed circulating water pool, this can make the periphery of air vent freeze, cause ice to block up, there is presently no the device reclaiming liquid nitrogen cold.
Utility model content
The purpose of this utility model is to provide a kind of liquid nitrogen off gas energy recovery device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of liquid nitrogen off gas energy recovery device, including main body, pipeline, import, outlet and baffle plate, described import includes coolant import and liquid nitrogen import, Pipe installing is provided with baffle plate in body interior and pipeline, coolant import and liquid nitrogen import are positioned at the same side of main body, and outlet is positioned at the opposite side of main body.
As further program of the utility model: be provided with flow switch between main body and outlet.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, and reasonable in design, detachability is good, it is simple to installs and changes；By using the pipeline of band baffle plate, liquid nitrogen tail gas retention time in the duct can be extended, thus the coolant in casing is fully lowered the temperature, reach neither to affect production cooling rate, again the cold of liquid nitrogen tail gas is made full use of thus reach energy-saving and cost-reducing purpose, improve the service efficiency of liquid nitrogen cold, using effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of liquid nitrogen off gas energy recovery device.
Wherein: 1-main body, 2-pipeline, 3-liquid nitrogen import, 4-coolant import, 5-flow switch, 6-baffle plate, 7-exports.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1, a kind of liquid nitrogen off gas energy recovery device, including main body 1, pipeline 2, import, outlet 7 and baffle plate 6, described import includes coolant import 4 and liquid nitrogen import 3, pipeline 2 is provided with baffle plate 6 in being arranged on main body 1 inside and pipeline 2, coolant import 4 and liquid nitrogen import 3 are positioned at the same side of main body 1, and outlet 7 is positioned at the opposite side of main body 1.It is provided with flow switch 5 between main body 1 and outlet 7.
Operation principle of the present utility model is: using the pipeline 2 of band baffle plate 6 to enter main body 1 as heat exchanging pipe, liquid nitrogen tail gas by liquid nitrogen import 3, the outside airtight water tank that makes connects with coolant.When in main body 1, liquid nitrogen tail gas passes through, being lowered the temperature by coolant in heat exchange feed-tank, for preventing the coolant in water tank from freezing, the coolant in water tank is circulated by pump.Because liquid nitrogen is amount of heat to be taken away when gasification, and speed is very fast, has baffle plate 6 by making in the pipeline 2 walk liquid nitrogen tail gas, and air-flow retention time in pipeline 2 increases so that fully lowering the temperature the coolant in casing.This apparatus structure is simple, and reasonable in design, detachability is good, it is simple to installs and changes；By using the pipeline 2 of band baffle plate 6, liquid nitrogen tail gas retention time in pipeline 2 can be extended, thus the coolant in casing is fully lowered the temperature, reach neither to affect production cooling rate, again the cold of liquid nitrogen tail gas is made full use of thus reach energy-saving and cost-reducing purpose, improve the service efficiency of liquid nitrogen cold, using effect is good.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to various changes can be made on the premise of without departing from this patent objective.
Claims (2)
1. a liquid nitrogen off gas energy recovery device, it is characterized in that, including main body, pipeline, import, outlet and baffle plate, described import includes coolant import and liquid nitrogen import, Pipe installing is provided with baffle plate in body interior and pipeline, coolant import and liquid nitrogen import are positioned at the same side of main body, and outlet is positioned at the opposite side of main body.
