Background
The petroleum storage tank fire accidents in the world occur at least 15-20 times every year, so that serious casualties and property loss are caused, and large-area environmental pollution is caused. According to the analysis of the operating condition of the oil tank, the fire protection by adopting the critical carbon dioxide fire extinguishing technology is an ideal choice. The carbon dioxide is used as a natural fire extinguishing agent, and has the characteristics of environmental protection, quick fire extinguishing, no damage to protected objects after fire extinguishing, low price of the fire extinguishing agent, no deterioration, long service time and the like. Compared with other fire extinguishing agents which can be applied to the project, the fire extinguishing agent has lower one-time investment and later use cost. The carbon dioxide fire extinguishing system under the condition of storage temperature (15 ℃) and pressure (5.17 MPa) is an engineering application state which is closest to a physical critical state and meets the requirements of engineering application performance and gives consideration to the economical efficiency of system investment cost, and can be called as engineering critical state carbon dioxide, which is called critical state carbon dioxide for short, namely the critical state created by the invention. The successful research and development of the system can integrally improve the self anti-explosion and explosion suppression, fire control and fire extinguishing capabilities of the large-scale petroleum storage tank, and provide a new method and new equipment for realizing the fire safety of national petroleum strategic reserves.

The data obtained by the test all reach the expected effect, but several new problems are found:
1. the flow distribution of the fire extinguishing agent is uneven, and the spraying pipeline is blocked by ice in time:
the conventional gas collecting pipe 22 is shown in fig. 3, and the structure adopts a straight line arrangement and adopts a blocking plate 25 structure on two sides. And the structure of the blocking plate 25 causes the flow of the fire extinguishing agent outlets 24 at two sides and the rest fire extinguishing agent outlets 24 to be uneven when the spraying is started, so that the dry ice blocking phenomenon occurs on the pipeline with overlarge flow.
2. Pressure difference of fire extinguishing agent spraying pipelines:
in the same way, because of the uneven flow distribution and the ice blockage phenomenon, the pressure difference in the spraying pipelines with the same length is larger, so that the spraying effect of the end nozzle cannot be ensured, and the fire extinguishing effect is further influenced;
3. the fire extinguishing agent has large spraying pressure loss:
when the fire extinguishing agent is sprayed, the fire extinguishing agent can form a large recoil force when impacting the blocking plates 25 on the two sides of the gas collecting pipe 22, and the recoil force collides with the normally sprayed fire extinguishing agent, so that a large pressure loss is caused.
