A remote monitoring and multi-channel self-regulating desuperheating system

Abstract

The invention relates to a remote monitoring and multi-channel self-adjusting desuperheating system, which relates to a desuperheating system in which the number of nozzles is self-adaptive and corresponding to opening and closing control under different desuperheating water pressures. , and requires complex working conditions that can maintain good atomization under various working conditions. Including steam pipeline, medium pressure self-operated pressure regulating valve, high pressure self-operated pressure regulating valve, medium pressure nozzle and high pressure nozzle. The annular desuperheating water pipe is located on the outside of the steam pipe, and the inner side is a double-reduced inner bushing; one side of the annular desuperheating water pipe is connected with a water inlet flange, and the middle part is divided into two distributions to connect to low-pressure nozzles; one low-pressure nozzle is connected to medium-pressure self-supporting A low-pressure pressure regulating valve is installed between the two; another low-pressure nozzle is connected to a high-pressure self-operated pressure regulating valve, and a low-pressure pressure gauge is installed between the two; the medium-pressure nozzle is behind the medium-pressure self-operated pressure regulating valve The middle pressure transmitter and the medium pressure gauge are distributed between the two.

Description

Technical field [0001] A remote monitoring and multi-channel self-adjusting cooling system of the present invention relates to a temperature reduction system in which the number of nozzles at different temperature-reducing water pressures adaptively corresponds to the opening and closing control, especially for the unstable on-site process conditions, a large range of regulations, and the need for various working conditions can maintain good atomization of complex working conditions. Background [0002] With the increasing requirements of national energy and environmental protection policies, steam as a wide range of use of media, the use of its efficiency assessment is becoming more and more stringent. At present, the centralized supply of steam to the surrounding area through the heat center is becoming the mainstream, and different downstream enterprises need different temperature steam is ultra-high temperature steam through the temperature reduction system at all levels for...

Problems solved by technology

In the actual production process, the steam load varies greatly. The conventional desuperheater can usually guarantee the desuperheating effect under the condition of large load, corresponding to the large number of desuperheater nozzle openings; Smaller, and the pressure of desuperheating water required for small loads is also low. At this time, when the desuperheater nozzles are fully opened, there is not enough desuperheating water and steam pressure difference to atomize the desuperheating water; therefore, the above small load situation cannot achieve better The atomization effect of the steam cannot ensure the best cooling effect of the steam
