Five-level vacuum pump configuration system and application thereof

Abstract

The invention relates to a fiver-level vacuum pump configuration system and an application thereof. The system comprises a B1 booster pump, wherein the inlet and the waste gas inlet of the B1 booster pump are communicated with each other, the B1 booster pump is communicated with the inlet of a C1 condenser by a B2 booster pump and a B3 booster pump, the first outlet of the C1 condenser is connected with the first inlet of a C2 condenser by an S4A injection pump, the second outlet of the C1 condenser is connected with the second inlet of the C2 condenser by an S4B stop valve and an S4B injection pump, the first outlet of the C2 condenser is connected with the inlet of a C3 condenser sequentially by an S5A stop valve and an S5A injection pump, the outlet of the C3 condenser is communicated with a waste gas outlet by the S5A tail gas stop valve, and the second outlet of the CS condenser is divided into two paths to be respectively communicated with the waste gas outlet by a pump stop valve and a water ring pump. According to the invention, the technical problem that steam quantity generated by converter steelmaking cannot maintain steam consumption of a full-steam vacuum pump system of a vacuum external refining device of the same tonnage is solved, and the investment problem of overhigh construction cost of a full-mechanical vacuum pump system is avoided.

Description

technical field [0001] The invention relates to the field of vacuum technology in the steelmaking industry, in particular to a five-stage vacuum pump configuration system and its application. Background technique [0002] As the focus of the steelmaking industry shifts from the pursuit of output growth to the pursuit of increasing varieties and improving quality, the vacuum refining of molten steel outside the furnace will be further popularized and developed. The core of vacuum refining lies in the entire vacuum pump system, whose performance not only determines the effect of vacuum refining, but also greatly affects the quality of products and the profits of enterprises. There are many configuration types of vacuum pumps, and different configuration types need to be selected according to the actual situation of the factory for different steelmaking plants. For the steel mills that currently use a large number of converter steelmaking, once the configuration type of the va...
