Description
Technical Field
The utility model relates to a heat energy equipment technical field specifically is a steam jet booster.
Background
Superheated steam desuperheaters are widely used in the steam power field to reduce the temperature of superheated steam to meet the requirements of power and heat transfer on steam. The traditional superheated steam desuperheater sprays the desuperheated water with pressure higher than steam pressure into steam flow, the water is vaporized and absorbs heat, and the steam cools. In actual use, the temperature reduction mode has many problems, namely, no high pressure exists on the site, a high-pressure water pump needs to be installed, and under most conditions, the temperature reduction water consumption is small, the high lift and low flow water pump are difficult to select types, a large-flow water pump is selected, a return water system needs to be added, so that the system is complex, and the power consumption is increased.
Disclosure of Invention
In order to solve the technical problem, the utility model discloses utilize steam to promote the pressure of water to being higher than steam pressure through injection apparatus, during the steam flow is again spouted into, make superheated steam desuperheat. The specific technical scheme is as follows:
the desuperheating water steam jet supercharger comprises a desuperheating water jet supercharger, a desuperheating water regulating valve and a desuperheater body, wherein the inlet end of the desuperheating water jet supercharger is connected with a high-temperature steam pipe and a low-pressure desuperheating water pipe, and the outlet end of the desuperheating water jet supercharger is connected with the desuperheating water regulating valve; the outlet of the desuperheater water regulating valve is connected with a desuperheater body, and the desuperheater body is also connected with a high-temperature steam pipe.
The temperature reducer also comprises a DCS or an electric control box, and a temperature transmitter is arranged at the outlet end of the desuperheater body; the DCS or the electric control box is connected with the temperature transmitter.
The system also comprises an overflow valve, wherein the overflow valve is arranged at the joint of the desuperheating water jet supercharger and the desuperheating water regulating valve.
Leading out partial steam from the high-temperature steam pipe, entering a desuperheating water jet supercharger, forming high-speed airflow and low-pressure desuperheating water through a nozzle to perform momentum and heat exchange, increasing the pressure and temperature of the low-temperature water, entering a desuperheating water regulating valve, and then entering a desuperheater to be mixed and vaporized with the high-temperature steam, so that the temperature of the high-temperature steam is reduced; the water spraying amount is controlled by the temperature-reducing water regulating valve according to the signal of the temperature transmitter, and when the water pressure at the outlet of the temperature-reducing water spraying supercharger exceeds the standard, the water can overflow through the overflow valve.
The utility model has the advantages that: the utilization occasion of the superheated steam desuperheater can not be limited by a high-pressure water source, and the requirement can be met by low-pressure and low-temperature industrial water. Since high-pressure water is not used, power can be saved. Because the low-pressure water does not rise in temperature in the boosting process, the atomization evaporation distance of the desuperheater can be reduced, and the length of the desuperheater body can be reduced.
