Integrated steam exhaust temperature reduction pressurizer

Abstract

The invention relates to equipment for steam exhaust processing of a steam system, in particular to an integrated steam exhaust temperature reduction pressurizer particularly suitable for the occasions of steam exhaust recovery of a turbine system, a boiler system and the like. The integrated steam exhaust temperature reduction pressurizer comprises a body, a temperature reduction flow control ring, a pressure spraying nozzle and a mixing pipe. The pressure spraying nozzle is composed of a valve rod, a valve element and a Venturi sleeve tube, the valve element is installed at the tail end of the valve rod and sleeved with the Venturi sleeve tube, the Venturi sleeve tube and the body are welded and fixed, the middle of the valve rod is fixed in the body through a fixing part, a valve cover is installed on the upper portion of the valve rod, and the head of the valve rod is connected with an execution mechanism through a clamping block. The rear portion of the body is connected with the mixing pipe, and the mixing pipe is composed of an inlet flange and a Venturi tail pipe. A steam inlet flange is arranged at the position, near the head of the valve rod, of the fixing part, and a condensate water inlet flange is arranged on the other side of the fixing part. The temperature reduction flow control ring is installed in the part, under the condensate water inlet flange, of the body.

Description

technical field [0001] The integrated exhaust steam desuperheating supercharger of the present invention relates to a device for exhaust steam treatment in a steam system, and is especially suitable for exhaust steam recovery occasions such as a turbine system and a boiler system. Background technique [0002] In systems such as turbines and boilers, steam utilization is often a difficult problem for users. The higher the steam utilization rate, the lower the production cost, which can maximize the profit of the final product. For some equipment, the excess steam is directly discharged to cause a lot of waste. The low and low temperature of the existing steam system cannot be utilized by downstream equipment, and ordinary exhaust steam recovery devices cannot achieve a one-time increase in steam pressure and temperature, resulting in high steam recovery costs. purpose of invention [0003] The purpose of the present invention is to provide an integrated exhaust steam de...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an integrated exhaust steam desuperheating supercharger for the above shortcomings, which utilizes high-pressure, high-temperature steam turbulent characteristics and condensation at the front end The water is firstly mixed to lower the temperature, and then mixed with low-pressure and low-temperature steam for the second time, and finally reaches the medium-temperature and medium-pressure steam required by the downstream at one time, which solves the problem that the conventional waste steam recovery products can only control the pressure but not the temperature
