Condensate recovery device

System principle

   (1). The closed steam condensate recovery system is mainly composed of: boiler, indirect steam equipment, steam trap, recovery pipe network, water collection tank, high temperature condensate recovery device and electrical control system. Its working principle is that the saturated steam is sent from the boiler to the steam indirect heating equipment, and the latent heat of vaporization is released to form saturated water, which is quickly discharged by the steam pressure through the steam trap, lifted into the overhead pipe network, and concentrated into the water collection tank. The pressure of the water collecting tank can be calibrated by the pressure regulator according to the steam pressure of the equipment, the amount of condensed water and the resistance of the return water network. When the condensate in the water collection tank reaches a high water level, the high-temperature condensate recovery device automatically starts, and the return water is input into the boiler or sent to the deaeration tank or other heat-using places according to the enterprise's situation. When the water level in the water collection tank reaches the low water level, the recovery device automatically stops running. If during the pumping process of the recovery device, the boiler water level reaches the warning water level without the need for water replenishment, the recovery device will automatically send the water into the softened water tank.

(2) Condensate recovery device. The condensed water recovery device is composed of a high-temperature centrifugal pump, a self-operated pressure regulating valve, an injection pressure regulating valve, an exhaust device, and a booster device to achieve the purpose of preventing cavitation.
