Description

Blow-down cooling device for regular blow-down expansion vessel Technical Field The utility model relates to the technical field of blowdown flash vessels, in particular to a blowdown cooling device of a periodic blowdown flash vessel. Background The boiler blow-down water is introduced into a larger container for expansion and depressurization, the container is called a blow-down expansion container, and the two types of blow-down expansion containers can be separated into a periodic blow-down expansion container and a continuous blow-down expansion container according to different blow-down modes, the continuous blow-down expansion container is used for recovering working media and heat, the blow-down water is saturated water, the direct drainage can cause the loss of the working media and the heat, after the blow-down water is introduced into the expansion container, the volume is increased, the pressure is reduced, the corresponding saturated temperature and enthalpy value are reduced, a part of steam can be automatically vaporized, and the steam can return to a corresponding thermodynamic system, so that a part of working media and heat are recovered, however, during blow-down, the discharged high-temperature sewage often has a plurality of problems. The utility model provides a regular blowdown flash vessel, which relates to the technical field of blowdown flash vessels and solves the technical problem of poor steam-water separation effect of the existing blowdown flash vessels in the prior art, and comprises a blowdown flash vessel body, wherein a sewage water inlet pipe, a steam outlet and a sewage water drain pipe are arranged on the blowdown flash vessel body, and a first mounting pipe seat and a second mounting pipe seat are respectively arranged on the sewage water inlet pipe and the sewage water drain pipe; the sewage draining and expanding device comprises a sewage draining and expanding device body, wherein a water-water separating component is arranged in the sewage draining and expanding device body and comprises an expanding ring, a straight line where the water inlet direction of a sewage inlet pipe is located is tangent to the expanding ring, sewage can move tangentially through the water-water separating component, steam can be formed conveniently, a throttle valve and a water level regulating valve can be installed through a first installation tube seat and a second installation tube seat, the sewage pressure is effectively reduced, the water level is controlled, the sewage can be expanded and cooled conveniently in the sewage draining and expanding device body, the sewage draining and expanding device is convenient and fast to use and operate, and the water-water separating effect is remarkable.
