Abstract
The utility model discloses a kind of cryogen retracting device, including tank between compressor stage, between described compressor stage, tank is connected with MRC refrigerant compressor one section outlet and cryogen recycling can respectively by pipeline, and tank is connected with MRC refrigerant compressor two-stage nitration entrance by pipeline between described compressor stage, between described compressor stage, the pipeline between tank and MRC refrigerant compressor two-stage nitration entrance is connected to liquid bag apparatus, and described liquid bag apparatus is connected to cryogen recycling can by pipeline.This cryogen retracting device, collects the hydrops of the liquid bag of MRC refrigerant compressor two-stage nitration entrance, has saved cost, reduces the pollution to environment, and meanwhile, the cryogen that being overhauled by system shutdown needs to set fire torch reclaims, and has saved cost, has reduced the pollution to environment.
Description
Technical field
This utility model belongs to technical field of chemical, is specifically related to a kind of cryogen retracting device.
Background technology
During liquefying plant parking maintenance, need to emit, in prior art intrasystem for refrigerant cycle cryogen
In, this part cryogen is directly discharged to torch burning, thus causes waste, also has certain pollution simultaneously to environment.
During liquefying plant start-stop car and when system loading fluctuation is bigger, MRC refrigerant compressor two-stage nitration enters oral fluid and contains
Easily hydrops, in the prior art, this operative liquid cryogen is directly discharged into torch, causes the waste of resource, adds and produce into
This, also result in pollution to environment simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of cryogen retracting device, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, this utility model following technical scheme of offer: a kind of cryogen retracting device, including compressor
Inter-stage tank, between described compressor stage, tank is connected with MRC refrigerant compressor one section outlet and cryogen recycling can respectively by pipeline, and
Between described compressor stage, tank is connected with MRC refrigerant compressor two-stage nitration entrance by pipeline, tank and MRC cryogen between described compressor stage
Pipeline between compressor two-stage nitration entrance is connected to liquid bag apparatus, and described liquid bag apparatus is connected to cryogen recycling can by pipeline.
Preferably, described cryogen recycling can is connected by the inlet duct of tank between bypass duct with compressor stage.This practicality
Novel technique effect and advantage: this cryogen retracting device, collect the hydrops of the liquid bag of MRC refrigerant compressor two-stage nitration entrance,
Having saved cost, reduced the pollution to environment, meanwhile, the cryogen that being overhauled by system shutdown needs to set fire torch reclaims, and saves
Cost, reduces the pollution to environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: tank, 2MRC refrigerant compressor one section outlet, 3 cryogen recycling cans, 4 MRC refrigerant compressor between 1 compressor stage
Two-stage nitration entrance, 5 liquid bag apparatus.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
This utility model provides a kind of cryogen retracting device as shown in Figure 1, including tank 1 between compressor stage, described pressure
Contracting machine inter-stage tank 1 is connected with MRC refrigerant compressor one section outlet 2 and cryogen recycling can 3 respectively by pipeline, and described compressor
Inter-stage tank 1 is connected with MRC refrigerant compressor two-stage nitration entrance 4 by pipeline, tank 1 and MRC refrigerant compressor between described compressor stage
Pipeline between two-stage nitration entrance 4 is connected to liquid bag apparatus 5, and described liquid bag apparatus 5 is connected to cryogen recycling can 3, institute by pipeline
State cryogen recycling can 3 to be connected by the inlet duct of tank 1 between bypass duct with compressor stage.
Operation principle: in order to cost-effective, reduces the pollution to environment simultaneously, and we add on the basis of intrinsic
One cryogen recycling can 3, after system general overhaul is stopped by compressor stage between, liquid refrigerant in 1 imports cryogen recycling can 3
In；When hydrops occurs in the liquid bag of MRC refrigerant compressor two-stage nitration entrance 4, this part cryogen is imported in cryogen recycling can 3.?
After maintenance terminates, cryogen in cryogen recycling can 3 imported between compressor stage in tank by pipeline.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this
Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art
For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature
Carry out equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
