Description
Technical field
The utility model relates to a kind of equipment of field of heat exchange, in particular in a kind of carbon dioxide heat pump system two
Carbonoxide recover.
Background technique
Now on the market, carbon dioxide recovery device is mainly used in CO2 heat pump system, his main effect is collection liquid
The CO2 of state and bring the lubricating oil in the compressor in system into.Existing CO2 recover is as shown in Figure 1, including shell and by shell
The cavity of formation, wherein the case top is provided with the air inlet being connected with cavity, and the end being connected to air inlet
End opening protrudes into the air inlet pipe in cavity, and housing central section is provided with the gas outlet being connected with cavity, the housing bottom setting
There is the oil outlet being connected with cavity, since the pressure of inspiration(Pi) for the compressor connecting in CO2 heat pump system with gas outlet is very big, this
Liquid CO 2 may be sucked compressor return air mouth by kind gas outlet set-up mode directly from CO2 recover, cause liquid hammer existing
As being easily damaged compressor in this way.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of novel carbon dioxide recovery device, used by it
Technical solution is: a kind of carbon dioxide recovery device, including shell and the cavity formed by shell, wherein the case top is arranged
There is the air inlet being connected with cavity, and the distal opening being connected to air inlet protrudes into the air inlet pipe in cavity, in shell
Portion is provided with the gas outlet being connected with cavity, and the housing bottom is provided with the oil outlet being connected with cavity, and feature exists
In: the gas outlet is also connected with the escape pipe that distal opening protrudes into cavity, and the distal opening position of the escape pipe is wanted
Higher than the distal opening position of air inlet pipe.
The further technical characteristic of the utility model is: the oil outlet is connected with the oil return bend pipe protruded into cavity.
The further technical characteristic of the utility model is: the housing central section is additionally provided with carbon dioxide perfusing hole.
The further technical characteristic of the utility model is: the shell is provided with 3 fixing legs.
The beneficial effects of the utility model are:
Since the gas outlet is also connected with the escape pipe that distal opening protrudes into cavity, and the end of the escape pipe is opened
Mouthful position is higher than the distal opening position of air inlet pipe, and liquid carbon dioxide can be prevented to be inhaled into this way and connect with gas outlet
In the gas returning port of compressor, and it is effectively prevent the appearance of liquid hit phenomenon, extend carbon dioxide heat pump system compressor uses the longevity
Life.In addition, lubricating oil can be allowed to preferentially enter compression in this way since the oil outlet is connected with the oil return bend pipe protruded into cavity
Machine, impurity returns compressor in anti-locking system.In addition, the perfusing hole of CO2 heat pump system is opened on the pipeline of system more now,
When system is run, it is usually associated with very big vibration, these vibrations mostly come from the operation of compressor and the circulation of CO2, when
Between it is long, perfusing hole position may be revealed because of vibration, now be arranged on recycling shell collector, due to recover using branch
Foot fixation, such perfusing hole can be reduced to be influenced brought by vibration, and then reduces the maintenance work of system.
Detailed description of the invention
Fig. 1 is existing carbon dioxide recovery device structural schematic diagram；
Fig. 2 is the structure top view of an embodiment of the present invention；
Fig. 3 is the structure sectional view in the direction A-A in Fig. 2.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Fig. 2, a kind of carbon dioxide recovery device, including shell 1 and the cavity 2 formed by shell, wherein the shell
The air inlet 3 being connected with cavity is provided at the top of body, and the distal opening 4 being connected to air inlet protrude into cavity into
Tracheae 5, housing central section are provided with the gas outlet 6 being connected with cavity, and the housing bottom is provided with going out of being connected with cavity
Hydraulic fluid port 7, it is characterised in that: the gas outlet 6 is also connected with the escape pipe 11 that distal opening protrudes into cavity, and the escape pipe
11 distal opening position is higher than the position of the distal opening 4 of air inlet pipe.
In the present embodiment, the oil outlet 7 is connected with the oil return bend pipe 8 protruded into cavity.
In addition, in the present embodiment, the housing central section is additionally provided with carbon dioxide perfusing hole 9.
The shell is provided with 3 fixing legs 10.
Since the gas outlet 6 is also connected with the escape pipe 11 that distal opening protrudes into cavity, and the escape pipe 11
Distal opening position is higher than the position of the distal opening 4 of air inlet pipe, and liquid carbon dioxide can be prevented to be inhaled into and go out in this way
In the gas returning port of the compressor of port connection, and it is effectively prevent the appearance of liquid hit phenomenon, extends carbon dioxide heat pump system compression
The service life of machine.In addition, since the oil outlet 7 is connected with the oil return bend pipe 8 protruded into cavity, lubricating oil can be allowed in this way
Compressor is preferentially entered, impurity returns compressor in anti-locking system.In addition, the perfusing hole of existing CO2 heat pump system more open in
On the pipeline of system, system run when, be usually associated with very big vibration, these vibration mostly come from compressor operation and
The circulation of CO2, the time is long, and perfusing hole position may be revealed because of vibration, the perfusion of carbon dioxide described in the present embodiment
Mouth 9 is arranged on recycling shell collector 1, and since recover utilizes 10 fixation of fixing leg, such carbon dioxide perfusing hole 9 can
Brought influence is shaken to reduce, and then reduces the maintenance work of system.
It is all according to equivalent change made by the present utility model application the foregoing is merely the better embodiment of the utility model
With modification, it should all belong to the covering scope of the utility model patent, the protection scope of the utility model is subject to claims.
