Dynamic adjustment type sonic velocity variable supercharging heat-exchanging device

Abstract

The invention discloses dynamic regulation type sonic speed changing pressurization heat exchanging device, and comprises a front two-way pipe (1), a steam jet pipe (11), a middle three-way pipe (2), a middle two-way pipe (7), a diffusing pipe (13) and a rear two-way pipe (8). The steam jet pipe is coaxially arranged in the middle three-way pipe, the diffusing pipe is embedded between the middle two-way pipe and the rear two-way pipe, an adjustable core (3) is arranged between the middle three-way pipe and the middle two-way pipe, the adjustable core (3) can make axial fore and aft horizontal movement, the center thereof is provided with an axially interpenetrated mixing chamber (12), the mixing chamber consists of a conical curve line part and a horizontal straight line part, wherein, the conical curve line part is a flow regulating section (10) which is used for regulating the inlet water flow, and the horizontal straight line part is a state and pressure regulating section (9) which is used to regulate the steam water mixing ratio in the mixing chamber. The invention achieves the goal of dynamic regulation in the condition of not stopping the system operation when the steam water parameter changes, makes the steam water mixing mass ratio and pressure ratio in the heat exchanger be in the optimum condition, effectively reduces the equipment operation noise and the operating cost, as well as enhances the heat transfer efficiency and the operation safety.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and mainly relates to a dynamic adjustment type variable sound velocity booster heat exchanger. Background technique [0002] The well-known variable-sonic supercharged heat exchangers in China can only adjust the flow intermittently. When the heat load of the heat exchanger changes, or the parameters of steam and supply and return water change, the system cannot operate normally, and it cannot be adjusted immediately. If adjustment is required, the normal operation of the system can only be stopped, the equipment is dismantled as a whole, and the internal structure of the product is adjusted. Even when there is a slight change in the thermal load or operating parameters, it is impossible to continuously adjust the state of the mixture under a certain influent flow rate. The system operates in a non-optimal operating state, which reduces heat exchange efficiency and operational safety. Co...
