Waste steam heating, pressurizing and recycling system

Abstract

The invention relates to a waste steam heating, pressurizing and recycling system which comprises a recycling tank, a primary jet pump and a secondary jet pump, wherein the recycling tank is a horizontal recycling tank, the top of the recycling tank is provided with a high-pressure steam outlet, the recycling tank is provided with a jet pipeline, a high-pressure draining pump is arranged on the jet pipeline, a jet inlet of the primary jet pump and a jet inlet of the secondary jet pump are connected with the jet pipeline, an outlet of the secondary jet pump is connected with an inlet of the recycling tank, a suction inlet of the secondary jet pump is connected with an outlet of the primary jet pump, a suction inlet of the primary jet pump is connected with an exhaust steam source through a low-pressure exhaust steam pipeline, and the high-pressure steam outlet is connected with a high-pressure steam recycling pipeline. The waste steam heating, pressurizing and recycling system disclosed by the invention is beneficial to solution to the problems of recycling difficulty caused by too low pressure of exhaust steam and pressurizing difficulty in the prior art and has the capability of effectively pressurizing the low-pressure exhaust steam, and the pressurized steam can be suitable for various occasions and especially suitable for occasions with high pressure requirements.

Description

technical field [0001] The invention relates to a waste steam pressurization system, which is used for recovering and reusing the waste steam after stripping temperature and pressure. Background technique [0002] The exhaust steam formed after the high-temperature and high-pressure steam completes work in the heat engine often contains a large amount of heat energy. In order to reduce energy waste, people hope to recycle this heat energy. However, due to the low pressure of exhaust steam and the difficulty of pressurization, it is There are few suitable occasions in production, so a large part of exhaust steam and the heat energy contained in it will be directly discharged into the atmosphere, which not only wastes a lot of heat energy, but also easily causes thermal pollution to the environment. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the present invention is to provide a waste steam stripping t...
