Abstract
The utility model discloses a pressure release device of a liquid carbon dioxide storage tank. The pressure release device comprises a stop valve a, a stop valve b, a gasifying station and a pressure reduction valve, wherein the stop valve a, the gasifying station, the stop valve b and the pressure reduction valve are sequentially communicated with one another through pipelines; the pressure reduction valve is communicated with a carbon dioxide main pipeline; the pressure reduction valve is an electrical control valve and is required to be grounded; the stop valve a is communicated with the carbon dioxide storage tank through a pipeline; and the carbon dioxide storage tank is communicated with the carbon dioxide main pipeline through a stop valve c, a pressure meter and a pipeline. By the pressure release device, during pressure release, gaseous carbon dioxide eliminated by pressure release is directly discharged into the main pipeline, so that the problem that the gaseous carbon dioxide is wasted during pressure release because of high pressure in the tank is effectively solved; the safety coefficient of liquid carbon dioxide storage is reduced; waste of carbon dioxide is reduced; and the utilization rate of carbon dioxide in a company is improved.
Description
Technical field
The utility model relates to a kind of novel wet tank pressure relief device, specifically relates to a kind of pressure relief device of liquid carbon dioxide storage tank.
Background technique
Use canned carbon dioxide in the chemical industry at present, after reaching certain numerical value, tank body pressure needs the high pressure relief in the tank is operated, if the simultaneously untimely pressure in the tank is got rid of, can cause security incident, in the process of pressure release, all need to discharge the finished product carbon dioxide in tank, on average the moon discharges available carbon dioxide 2-3 ton at least, causes very large waste to manufacturer at every turn.
The model utility content
Technical problem to be solved in the utility model provides a kind of reliable performance, simple in structure, the pressure relief device of practical liquid carbon dioxide storage tank.
For reaching above-mentioned technique effect, the utility model comprises: stop valve a, stop valve b, vaporizing station and reduction valve, described stop valve a, vaporizing station, stop valve b and reduction valve are communicated with successively by pipeline, described reduction valve is communicated with the carbon dioxide main line, and stop valve a is by pipeline communication carbon dioxide storage tank; The carbon dioxide storage tank is by stop valve c, pressure gauge and pipeline communication carbon dioxide main line.
Preferably, described reduction valve is the electrical control valve, needs grounding connection.
The beneficial effects of the utility model:
The utility model is by increasing pressure relief device, so that when pressure release, the gaseous carbon dioxide that pressure release is got rid of directly enters main pipe, effectively solved because of the tank internal pressure high, the problem that causes waste gaseous carbon dioxide in pressure leak process, reduce the safety coefficient of hydraulic pressure carbon dioxide storage, reduced the waste of carbon dioxide, improved the utilization ratio of company's carbon dioxide.
Description of drawings
Fig. 1 is the utility model linkage structure schematic diagram.
Wherein: 1-carbon dioxide storage tank, 2-stop valve a, 3-vaporizing station, 4-stop valve b, 5-reduction valve, 6-stop valve c, 7-pressure gauge, 8-carbon dioxide main line.
Embodiment
As shown in Figure 1, the pressure relief device that the utility model discloses a kind of liquid carbon dioxide storage tank comprises stop valve a2, stop valve b4, vaporizing station 3 and reduction valve 5, described stop valve a2, vaporizing station 3, stop valve b4 and reduction valve 5 are communicated with successively by pipeline, reduction valve 5 is the electrical control valve, need grounding connection, reduction valve 5 is communicated with carbon dioxide main line 8, and stop valve a2 is by pipeline communication carbon dioxide storage tank 1; Carbon dioxide storage tank 1 is by stop valve c6, pressure gauge 7 and pipeline communication carbon dioxide main line 8.
The utility model is by increasing pressure relief device, so that when pressure release, the gaseous carbon dioxide that pressure release is got rid of directly enters main pipe, effectively solved because of the tank internal pressure high, the problem that causes waste gaseous carbon dioxide in pressure leak process, reduce the safety coefficient of hydraulic pressure carbon dioxide storage, reduced the waste of carbon dioxide, improved the utilization ratio of company's carbon dioxide.
Above-described only is preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, as the common practise of related domain, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model.
