Description
Technical field
The utility model relates to carbon dioxide cascade refrigeration field, in particular to a kind of carbon dioxide cascade refrigeration system is special
Use circulation barrel.
Background technique
With the enhancing of people's environmental consciousness and the implementation of national sustainable development policy, freon substitution has been compeled in eyebrow
Eyelash.For CO2 as a kind of natural refrigerant, having depletion of the ozone layer index is zero, and chemical property is stablized, and unit volume freezes
Advantages, the CO2 refrigeration systems such as amount is high, and viscosity is low are slowly received by everybody.But due to the physical characteristic of CO2 --- with temperature
The raising of degree, pressure change is very fast, and pressure value is very high.Therefore the refrigeration system relative to other refrigerants of use,
CO2 subcritical refrigeration system, which needs to increase, maintains unit to cool down when CO2 temperature is raised to setting value to it to maintain pressure.Mesh
Before, widespread practice is to increase case tube heat exchanger on CO2 circulation barrel.Case tube heat exchanger is welded on staving by pipeline, in
Between be equipped with flange.A possibility that major defect existing for this way is that flange arrangement is too many, considerably increases leakage, CO2 phase
For other refrigerant pressures height, it is easier to leak；It is only connect by 2 to 3 root canal roads with staving, heat exchange efficiency is poor；Exchange heat body
Product is big, increases staving height, and cost is high.Utility model content
It is multiple that in order to make up for the defects of the prior art, the utility model provides a kind of carbon dioxide of built-in heat exchange plate tubular type
Cascade refrigeration system Special circulation bucket.
The utility model is achieved by the following technical solution: a kind of carbon dioxide cascade refrigeration system Special circulation
Bucket, including staving are additionally provided with the fixed cross-arm of several coil pipes if the staving surface is equipped with dry coil pipe interface in the staving,
It is fixedly connected with heat exchange coil on the fixed cross-arm of the coil pipe, the heat exchange coil is connect with coil pipe interface；The staving bottom is also
Equipped at least two gas phase interfaces, gas phase adapter tube is equipped on each gas phase interface, the gas phase adapter tube is located in staving
And gas phase adapter tube upper end is located at staving middle and upper part.
The fixed cross-arm of the coil pipe is located at middle and upper part in staving.
Gas phase adapter tube upper end is bent downwardly, and nozzle is directed downward.The beneficial effects of the utility model are:
Heat exchange coil is set up directly on inside CO2 staving by the utility model compared with traditional circulation barrel, without any method
Blue structure, a possibility that reducing leakage；Heat exchange coil is evenly distributed on inside staving, than external heat exchanger structure heat exchange efficiency
It is higher；Such design structure simplifies, and is not take up a barrel outer volume, does not increase device height, and cost reduces；Increase in staving bottom side
Add a gas phase interface, facilitate connection pressure sensor, the components such as pressure gauge and pressure-equalizing pipe connect without drawing at the top of bucket.
Convenient for operating and observing.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings:
Fig. 1 is the utility model schematic view of the front view；
Fig. 2 is the utility model A-A sectional view；
Fig. 3 is the utility model left view structural representation.
In figure, 1 staving, 2 heat exchange coils, 3 coil pipe interfaces, the fixed cross-arm of 4 coil pipes, 6 gas phases adapter tube, 7 gas phase interfaces.
Specific embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figure 1 to Figure 3, a kind of carbon dioxide cascade refrigeration system
Special circulation bucket, including staving 1, if 1 surface of staving is equipped with dry coil pipe interface 3, middle and upper part is additionally provided with several disks in staving 1
Pipe fixes cross-arm 4, is fixedly connected with heat exchange coil 2 on the fixed cross-arm 4 of coil pipe, heat exchange coil 2 is connect with coil pipe interface 3；1 bottom of staving
Portion is additionally provided at least two gas phase interfaces 7, and gas phase adapter tube 6 is equipped on each gas phase interface 7, and gas phase adapter tube 6 is located in staving 1
And 6 upper end of gas phase adapter tube is located at 1 middle and upper part of staving.6 upper end of gas phase adapter tube is bent downwardly, and nozzle is directed downward.
The utility model by heat exchange coil 2 be arranged inside staving 1, be fixed on cross-arm, be arranged position in bucket on
The postrun vapor phase areas in portion, i.e. system, coil pipe interface 3, which connects, when use maintains unit, i.e. heat exchange coil is as maintaining unit
Evaporator, to realize to the decrease temperature and pressure of CO2 gas, such method helps to enhance the heat exchange efficiency of heat exchange coil 2；In bucket
Body bottom is equipped with gas phase interface 7, and gas phase interface 7 is connect with gas phase adapter tube 6, and the intracorporal gas of bucket is oriented to gas phase by gas phase adapter tube 6
At interface 7, the components such as connection pressure sensor, pressure gauge, pressure balance table can be installed at gas phase interface 7, directly in bucket
Bottom, which is drawn, to be connect, easy to operate, and is observed convenient for data.
In addition to the technical characteristic described in the specification, remaining technical characteristic is technology known to those skilled in the art.
