Product Application
◆ Combined heat and power heating network for centralized heating.
◆Power stations or industrial boilers and thermal power plants.
◆Heat exchange station or heat exchanger steam inlet.
◆Steam power inlet of lithium bromide refrigeration unit.
◆Power and heat consumption of production process equipment such as petrochemicals, light textiles, papermaking, pharmaceuticals, and food.
This device consists of a control system, a pressure reduction system, a water spray cooling system and a safety protection system. Its characteristics are as follows
◆The main controller of the control system adopts an imported high-precision multi-function digital controller with powerful functional components. Friendly human-machine interface
and fast and accurate control loop enable intelligent unattended operation, flexible adjustment of parameter settings, and function expansion according to user requirements.
◆The pressure reducing device is the part that realizes throttling and reducing the pressure of high-pressure steam to the pressure required by the user. It consists of a balanced electric pressure reducing valve, a pressure sensor, a multi-function controller and a throttling device. The sensor is installed downstream of the steam pipeline to monitor the decompressed steam pressure in real time and adjust the valve opening in (proportional-integral) mode. No matter how the upstream pressure changes or the downstream load changes, the downstream steam pressure remains stable.
◆Desuperheating device: It is the part that realizes the reduction of steam temperature. It consists of a desuperheating body and a desuperheating water system. The desuperheating body is directly connected to the steam pipe
. The desuperheating water enters the desuperheating body through a water pump at high pressure. , spray atomized fine water droplets through the nozzle, quickly mix with the superheated steam, vaporize, absorb the heat energy of the superheated steam, and reduce the temperature of the superheated steam. According to the feedback signal from the downstream temperature sensor, the control system mode adjusts the waterway regulating valve and adjusts the temperature reduction. The original professionally designed nozzle imported from the United States is made of stainless steel and is equipped with rotating blades inside. The water droplets ejected are powerful and spiral-supported. Movement is conducive to vapor absorption, effectively avoiding cavitation/flash evaporation, the particles are small and uniform, and the atomization effect is significant.

Safety guidance
◆A fixed bracket should be installed under the safety valve, and the pressure relief should be discharged to a safe place
◆Ensure a certain installation distance from the high wall above the ground , for safe maintenance
◆ Stop valves should be installed at the front and rear, and bypasses should be added for maintenance.
◆A drain valve should be installed at the lowest point of the pipe at the rear of the temperature and pressure reducing device.
◆Thermometers and pressure gauges should be installed before and after the temperature and pressure reducing device
◆A filter is installed in front of the device and is directly connected to the pressure reducing valve body.
