Description
Technical field
A kind of retracting device is the utility model is related to, is to be related to a kind of emptying high-pressure carbon dioxide gas to return in particular
Receiving apparatus.
Background technology
In food-grade carbon-dioxide Project design, CO 2 raw material gas uses the dioxy of 98% concentration of synthesis ammonia by-product
Change carbon gas, the carbon dioxide gas of 98% concentration of this by-product is shared with other devices.In actual production, existing synthesis ammonia by-product
98% carbon dioxide gas can not meet two covering devices while use, due to material gas quantity deficiency, carbon dioxide plant is begun
It can not be produced at full capacity eventually.
Existing food-grade carbon-dioxide device as shown in Figure 1 first buffers unstripped gas by surge tank, rear to utilize two
98% carbon dioxide gas for synthesizing ammonia by-product is compressed to 2.2MPa and delivers to desulfurizer, purifier, dry successively by compressor
Dry device, liquefying plant, purifying plant each operation, finally produce qualified food-class liquid CO 2, and technological process is shown in
Schematic diagram, this method are produced food-grade carbon-dioxide, CO 2 raw material gas need to pressed using carbon-dioxide gas compressor
Contracting, power consumption is produced, improve production cost, and fluctuation be present because upstream synthetic ammonia installation produces, often result in food-grade two
Carbonoxide device passively stops.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided one kind emptying high-pressure carbon dioxide gas
Retracting device, existing production status can be changed, realize the stable full production of carbon dioxide plant, and reduce and be produced into
This.
The purpose of this utility model is achieved through the following technical solutions.
A kind of emptying high-pressure carbon dioxide gas recovering device of the present utility model, including it is de- in carbon dioxide generator
Turbocompressor in sulphur device and synthetic ammonia installation, the outlet of the turbocompressor are connected by feed-line and downstream unit
Connect, be sequentially connected between the outlet of the turbocompressor and the import of desulfurizer along gas flow direction by recovery line
There are No.1 stable-pressure device, No. two stable-pressure devices, high-pressure buffering pot and decompressor, the delivery outlet of the No.1 stable-pressure device passes through
Pipeline is connected with downstream unit.
Compared with prior art, beneficial effect caused by the technical solution of the utility model is：
The utility model realizes the stable full production of food-grade carbon-dioxide device, without using pressurized carbon dioxide
Contracting machine, save former technique and use power consumption caused by carbon-dioxide gas compressor, reduce production cost, and reclaim substantial amounts of
Carbon dioxide is dropped a hint, and protects environment.
Brief description of the drawings
Fig. 1 is existing productive technology of carbon dioxide flow path device schematic diagram；
Fig. 2 is emptying high-pressure carbon dioxide gas recovering device schematic diagram of the present utility model.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 2 a kind of emptying high-pressure carbon dioxide gas recovering device of the present utility model, including carbon dioxide production
The turbocompressor in desulfurizer and synthetic ammonia installation in device, the high pressure section outlet of the turbocompressor pass through conveying
Pipeline is connected with downstream unit.Along gas flowing side between the high pressure section outlet and the import of desulfurizer of the turbocompressor
No.1 stable-pressure device, No. two stable-pressure devices, high-pressure buffering pot and decompressor are connected with turn to by recovery line, that is,
Described No.1 stable-pressure device one end is connected with feed-line, and the other end is connected with No. two stable-pressure devices.The No.1 voltage stabilizing
The delivery outlet of device is connected by pipeline with downstream unit, that is, the recovery between No.1 stable-pressure device and No. two stable-pressure devices
Pipeline is connected by pipeline with downstream unit.The present apparatus is without using carbon-dioxide gas compressor, but the surge tank in original device
With compressor without remove can be used as it is standby.
The course of work of the present apparatus is as follows：Turbocompressor outlet 8.1MPa carbon dioxide is dropped a hint in synthetic ammonia installation
A part returns to downstream unit, and another part uses through No.1 stable-pressure device victual grade carbon-dioxide device.Specially
When No.1 stable-pressure device delivery outlet pressure is higher than 7.6Mpa, carbon dioxide is dropped a hint through No. two stable-pressure devices, high-pressure buffering pots
Decompressor decompression victual grade carbon-dioxide device is delivered to use；When No.1 stable-pressure device delivery outlet pressure is less than 7.6Mpa
When, carbon dioxide, which is dropped a hint, delivers to downstream unit use.
Opened by No.1 stable-pressure device and the shut-in time, calculate high-pressure buffer tank volume.In this period, high-pressure buffer
Pressure inside the tank fluctuates in 7.0~3.0MPg.Being decompressed to 2.2MPa victual grade carbon-dioxide devices by decompressor makes
With progress subsequent production.High-pressure buffering pot may insure stable food-grade carbon-dioxide device production tolerance.
Although the utility model is described above, the utility model is not limited to above-mentioned.
