Temperature and Pressure Reduction Device System

Product Introduction

The temperature and pressure reduction device system consists of pressure reducing system, temperature reducing system, safety protection device and automatic control device.

Modern power engineering and thermal technology require high temperature and high pressure boilers to produce superheated steam with extremely high superheat.However, for some equipment processes, such steam may be too dry or too hot.For example, when heat exchangers are used in process operations, the use of superheated steam reduces efficiency due to low heat transfer coefficient, and the use of saturated steam is more suitable.In addition, when the dry saturated steam at high pressure is reduced to low pressure, superheat will be generated at the downstream outlet.This requires cooling the superheated steam to the desired near-saturation temperature, which requires a desuperheater.In many cases it is necessary to simultaneously reduce and decompress the high pressure superheated steam. The temperature reducing and pressure reducing device is an efficient energy saving and environmental protection product.The temperature reducing and pressure reducing device is equipped with the corresponding industrial automation instrument (namely the thermal control cabinet), which can reduce the temperature and pressure of the primary (new) steam pressure P1 and temperature T1 transmitted from the power station or industrial boiler and thermal power plant, so that the secondary steam pressure P2 and temperature T2 can meet the requirements of the production process.Widely used in thermal power plant, central heating, food industry, petrochemical industry, textile industry, rubber industry, paper and pulp industry, tobacco industry, pharmaceutical and many other industries.In order to meet the technical requirements of different equipment, our company provides different types of temperature reducer (temperature reducer, pressure reducer), and achieve a full set of intelligent automatic control or DCS system network

Product Advantage

There are many types of desuperheater, but the spray desuperheater is the most widely used. The desuperheater process is mainly realized by spraying desuperheater into the steam through the nozzle. The atomization effect of desuperheater determines the performance, service life and secondary steam temperature of the desuperheater, and the structure of the nozzle is the main factor affecting the atomization of desuperheater

Product Structure

The temperature and pressure reduction device system is composed of a control system, a pressure reducer system, a water-jet temperature reducer system and a safety protection system.

The nozzle of ordinary structure is fixed flute nozzle installed directly on the main road.The nozzle is a cylindrical structure, and there are many small through holes on its surface, which are used for water spray and temperature reduction.When the desupregulated water is in the normal flow, the flute nozzle can be better mixed medium for cooling.When the desuperative water is at a small flow rate of 10%-30%, because the flow cross-sectional area of the flute nozzle is fixed, when the pressure parameters of the steam or desuperative water fluctuate greatly, the desuperative temperature effect will be reduced, and the desuperative atomization will become worse, which will easily lead to water shock caused by water filling in the main pipe.The outlet steam adjustment range of ordinary structure temperature reduction and pressure reduction device is only 30%-100%
