Steam ejector (also called steam injection heat pump, thermocompressor) is widely used in textile, papermaking, petroleum, thermoelectric and other industries that use steam as power. It is mainly used to promote steam circulation and improve low-pressure steam. pressure. Enterprises in these industries generate low-pressure steam during the production process, and there may be multiple levels of pressure steam in a production plant or workshop.
1. Power plant: Many large and medium-sized enterprises have their own thermal power plants, which supply steam through the extraction and back pressure of the steam turbine. However, since the extraction pressure (back pressure) of the steam turbine design is fixed, it often happens that the steam supply of the steam turbine cannot meet the production needs. The steam ejector can be used to ejector the extraction steam or exhaust steam of the steam turbine by using the fresh steam from the boiler. Boost it to meet user requirements.
2. Spent steam and waste heat recovery: Use higher pressure steam to inject lower pressure steam to obtain steam at a certain pressure in the middle to achieve the purpose of "low product, high use" or waste heat utilization. In the process, the waste steam is recycled to reduce emptying and save 14% of steam consumption.
3. Condensed water and flash steam recovery: Recover the condensed water and flash steam generated by steam heating in the production process. Boosting pressure.
4. While injecting low-pressure steam, it can be used as a desuperheating and pressure reducer and the requirement for desuperheating water pressure is reduced.
