Abstract
The utility model relates to a recovery device of boil-off gas from a carbon dioxide storage tank, comprising a storage tank and a carbon dioxide compression system. A boil-off gas discharge tube is arranged on the storage tank and the discharge flow is controlled by a boil-off gas valve. The utility model is characterized in that the boil-off gas discharge tube is communicated with a connection pipe and is communicated with a feed gas pipe; a pressure reducing valve is arranged at the boil-off gas discharge tube in front of the connection pipe; the feed gas and the boil-off gas enter the carbon dioxide compression system through a filter valve group after being mixed. The utility model fully recycles the carbon dioxide boil-off gas with higher purity. After mixed with the carbon dioxide, the purity of the feed gas is increased, which is more favorable for gas liquefaction and greatly improves the production efficiency.
Description
Technical field
The utility model relates to technical grade liquid carbon dioxide gas concentration unit, particularly the technical grade liquid carbon dioxide gas device that vaporized gas reclaims in storage tank.
Technical background
In carbon dioxide production, the storage and transport process, owing to himself physical property, can not be as ultralow temperature low pressure accumulatings such as oxygen, nitrogen, argons, full gaseous state accumulating is the cost efficiency extreme difference especially.And pressure (accumulating between 2.0～2.5MPa) low temperature (-20 ℃～-35 ℃) in adopting.Again in the storage and transport process, the liquid carbon dioxide evaporation can not superpressure for guaranteeing container pressure, keeps lower temperature again, can only arrange it to boil-off gas one.
Common way is in the said circumstances:
1. enter atmosphere after utilizing the part cold, waste bigger.
2. increase by a small frozen system in the tank field, can effectively deal with problems, but the complicated input of process is bigger.
Summary of the invention
The utility model utilizes the original production device for overcoming above-mentioned shortcoming, provides a kind of simple and compact for structure, to the device of carbon dioxide storage tank boil-off gas recycling.
The technical solution of the utility model is: a kind of carbon dioxide storage tank gas recovering device, comprise storage tank, after liquid carbon dioxide evaporates in the storage tank, become gaseous carbon dioxide, discharge by the boil-off gas pipeline by the control of the boil-off gas valve on the storage tank, discharge pressure is 1.8～2.0MPa, be decompressed to 0.05～0.1MPa by reduction valve, increase a connecting pipeline between boil-off gas discharge pipe and the raw material pipeline, after boil-off gas and unstrpped gas are mixed, after the virgin gas temperature descends, there are more moisture content to separate out, enter the filter tap group and filter, compress, fill as product then by the carbon dioxide compression system.
Wherein said reduction valve can make its pressure by higher pressure in the storage tank decompression of carbon dioxide storage tank boil-off gas, reduces to a little more than CO 2 raw material gas pressure, and boil-off gas is directly introduced in the mother tube, mixes with virgin gas.
The utility model equipment modification is simple, drops into for a short time, has fully recycled boil-off gas, carbon dioxide boil-off gas purity is higher, after feed carbon dioxide is mixed, virgin gas purity is improved, be more conducive to gas liquefaction, reduce the virgin gas water content, enhance productivity more greatly.
