Condensation automatic water return system

Abstract

The invention discloses an automatic condensation water return system which is characterized in that a condensation water recovery tank is connected with a boiler through a deaerator; the deaerator comprises a deaeration head and a water storage tank; the deaeration head is connected with the condensation water recovery tank through a steam pipeline; the bottom of the water storage tank is provided with a communicating pipeline; the bottom of the condensation water recovery tank communicates with the bottom of the deaerator through the communicating pipeline; an electric valve is arranged in the middle of the communicating pipeline; the top of the condensation water recovery tank is provided with an automatic pressure regulating device; the automatic pressure regulating device is used for regulating the steam pressure of the condensation water recovery tank through a pressure regulating valve; the side end of the condensation water recovery tank is provided with a liquid level meter. By using the automatic condensation water return system, the self working pressure of the condensation water recovery tank can be regulated, and the pressure difference between the condensation water recovery tank and the deaerator is made artificially, so that the automatic control of liquid levels of the condensation water recovery tank and the deaerator can be realized; and the deaerator head is used for carrying out thermal deaeration on reverse-osmosis water entering the deaeration head by virtue of flash vaporization steam generated by returned condensation water, and the communicating pipeline is used for returning condensation water to the deaerator, so that the equipment fault is reduced, water and electricity are saved, and equipment operation safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of planting nutrient solution, and in particular relates to a condensation automatic return water system. Background technique [0002] The deaerator is an alternative product of the spray packing deaerator. The replenishment water passes through the membrane tube in a spiral shape and is ejected at a certain angle to perform heat exchange and deaeration with the heating steam. The feed water is heated to the saturation temperature corresponding to the working pressure of the deaerator. , to remove oxygen and other gases dissolved in the feed water, how to design a deaerator with simple structure and efficient use in the condensing automatic return water system has important practical significance. [0003] The steam generated by industrial boilers is mostly used for indirect heat exchange. The condensed water after heat exchange is at a relatively high working pressure and temperature. Because of its high c...
