Description
Technical field
The utility model relates to a kind of retracting device system from heat exchange unit discharge condensate water, a kind of specifically condensed-water recovering device.
Background technology
In the development of heat exchange unit, vapour-water heat exchange unit needs Condensate recovery device, and the water of recovery is discharged with water pump, because of the water that reclaims is saturation water, easily makes water pump generation cavitation, and therefore, Condensate recovery device needs high-order the installation.
Summary of the invention
Need high-order the installation in order to overcome existing Condensate recovery device, solve the cavitation problem that low level is installed water pump, the utility model provides a kind of novel condensed-water recovering device, and low level is installed, and prevents the condensed-water recovering device of water pump generation cavitation.
The technical scheme that its technical problem that solves the utility model adopts is: condensed-water recovering device is by low head, cylindrical shell, heat exchanger, the Condensate recovery device that upper cover etc. are formed, water pump and injector etc. are partly formed, cylindrical shell and low head and upper cover welding, at the bottom of cylindrical shell dress heat exchanger, the heat exchanger upper perforated plate drives the water hole into, side on cylindrical shell top, the condensate water water inlet pipe is housed, opposite side is equipped with manhole, liquid level gauge is equipped with at the middle part, blower line and safety valve are housed above the upper cover, blow-off pipe and outlet pipe are housed below the low head, thermometer is housed on the outlet pipe, outlet pipe links to each other with the water pump import, exit of pump links to each other with electric control valve, and control valve connects injector.Connect extraction steam pipe on the heat exchanger, extraction steam pipe is connected with injector, and injector connects drainpipe.Condensate water in the heat exchange unit enters Condensate recovery device by the water inlet pipe on the cylindrical shell, and the condensate water after the heat exchanger cooling enters water pump by outlet pipe, after control valve enters injector, flows out from outlet pipe then.Part water is by heat exchanger tube sheet inlet opening inflow heat exchanger cavity, and the pressure in the heat exchanger cavity is because the suction of injector forms negative pressure, under suction function, water becomes the saturated vapor under this negative pressure, absorbs heat, and temperature reduces, make heat exchanger tube keep low-temperature condition, reach the heat exchange purpose.Make condensate water obtain certain degree of supercooling.Reach the anti-cavitation purpose of water pump.Keep the Condensate recovery device liquid level by electric control valve.
The beneficial effects of the utility model are that low level is installed, and prevents cavitation, and is simple in structure, is convenient to make and maintenance.
