Abstract
The utility model discloses trichlorosilane product loading equipment, which mainly comprises a trichlorosilane tank, a tank truck tank and a pipe, wherein trichlorosilane tank and the tank truck tank are connected by the pipe; the trichlorosilane tank is provided with a feeding valve, a nitrogen valve and a relief valve; the tank truck tank is provided with a tank truck tank relief valve; the pipe is provided with a booster pump and a booster pump valve and is also provided with a nitrogen pipe; and the nitrogen pipe is provided with a nitrogen pipe valve. The structure of the equipment overcomes the drawbacks of the finished product tank and the loading pie by optimizing a loading pipe process and using a loading pump and the pipe with the valves; and by using nitrogen as power, loading speed is increased and aims of saving energy, reducing emission and increasing economic benefit are fulfilled. The equipment is simple and easy to operate; and the valves are arranged, so problems of material leakage, environment pollution and damage to operators are solved and loading cost is effectively controlled.
Description
Technical field
The utility model relates to a kind of chemical products carrier loader, relates in particular to a kind of equipment that is used for the trichlorosilane product loading.
Background technology
The trichlorosilane product is colourless transparent liquid, and is volatile, is prone to deliquescence, meets air and produces white cigarette, meets water decomposition, is dissolved in organic solvents such as benzene, ether.Belong to the one-level dangerous when wet, inflammable and explosive, meet the water reaction and produce hydrogen chloride gas; It and oxidizer generation kickback are met naked light, high burning or blast are taken place when hot.Storing mode is the canned of big volume.
At present; The technological process of domestic trichlorosilane product loading is roughly following: before the trichlorosilane product loading; At first be communicated with the slack tank car valve that links to each other with system, trichlorosilane tank car internal pressure is let out expansion tank before the machine through associated conduit, let out when minimum through loading platform; Utilize the difference of pressure that exists between finished product jar and the tank car, open related valve then and fill; When tank car does not reach filling weight yet if pressure is close, open side nitrogen valve pressurization on the finished product jar then, utilize nitrogen pressure that tank car is filled.Fill finish after, generally all more than 0.2MPa, in order to promote from the feed rate of trichlorosilane rectification column cat head trichlorosilane finished product toward the finished product jar, the finished product jar still needs pressure release to 0.1MPa to the finished product pressure tank, charging once more.Such entrucking method is wasted nitrogen (pressurising releases again) very much, and is uneconomical.Loading time is also at per car (30t) about 2 hours, and the time is longer.
Moreover original entrucking technology required time is longer, the time regular meeting have influence on production, and use nitrogen amount big, uneconomical during entrucking.In addition, if when company's nitrogen amount or nitrogen pressure are not enough, can have influence on loading speed even can entrucking, has influence on the ordinary production order of company.
The utility model content
In view of this, the purpose of the utility model provides a kind of equipment that is used for the trichlorosilane product loading.
The technical scheme of the utility model realizes with following method,
A kind of equipment that is used for the trichlorosilane product loading, mainly by the trichlorosilane storage tank, the tank car storage tank; Pipeline is formed, and trichlorosilane storage tank and tank car storage tank are through plumbing connection, and the trichlorosilane storage tank is provided with inlet valve; Nitrogen valve and blowdown valve, tank car storage tank are provided with tank car storage tank blowdown valve, wherein; Pipeline is provided with boost pump and boost pump valve, also is provided with nitrogen tube on the pipeline, and nitrogen tube is provided with the nitrogen tube valve.
Pipeline between boost pump and the trichlorosilane storage tank is provided with first valve and second valve.
Also be provided with the 3rd valve on the tank car storage tank.
Pipeline is provided with together regulating the valves of boost pump, the parallel connection of boost pump valve.
The good effect of the utility model technical scheme is:
The utility model structure is optimized entrucking pipeline technology to the deficiency of finished product storage tank and entrucking pipeline existence, selects Loading Pump for use and is provided with the pipeline of valve; And utilize nitrogen as power; Improved loading speed greatly, reached energy-saving and emission-reduction, the purpose of increasing economic efficiency.The utility model operating process is simple, is prone to left-hand seat; The installation of valve guarantees that material does not leak outside, and avoids environmental pollution, protection operator to preserve from, and effectively control the entrucking cost.

During use, the branch following steps are carried out:
1, closes inlet valve 4, nitrogen valve 5, blowdown valve 6.
2, open tank car storage tank blowdown valve 7, tank car storage tank 2 is carried out pressure release.
3, when the differential pressure of tank car storage tank 2 is following to 0.1Mp, open first valve 12 and second valve 14, close regulate the valves 13 with nitrogen tube valve 11.
4, start boost pump 8, open boost pump valve 9 and the 15 beginning entruckings of the 3rd valve.
When 5, entrucking finishes, close boost pump valve 9, close boost pump 8.
6, open nitrogen tube valve 11, with the remaining liquid of 3 li in nitrogen blow-off's pipeline.
7, close nitrogen tube valve 11 and the 3rd valve 15 and tank car storage tank blowdown valve 7.
