Hot-water type dynamic-regulating type steam-water direct-mixing type heat-exchanging device

Abstract

The invention belongs to a hot-water type dynamic-regulating type steam-water direct-mixing type heat-exchanging device, which comprises a front three-way pipe (1), a front core (2), a middle three-way pipe (3), a middle core (4), a long two-way pipe (5), a temperature sensor, an electric executing mechanism and a controller, wherein the front core (2) is coaxially arranged in the middle three-way pipe (3), the middle core (4) is nested between the middle three-way pipe (3) and the long two-way pipe (5), a regulating device (7) is arranged between the front core and the middle core, the regulating device can make axial forward and backward horizontal movement under the driving of the electric executing mechanism, the regulating device is formed from a water-direction regulating surface (14) and a steam-direction regulating surface (15), the magnitude of the steam quantity is controlled by adjusting a variable sectional area formed from the steam-direction regulating surface and the inner wall surface of a front-core nozzle, and the magnitude of the inlet-water quantity is controlled by adjusting the variable sectional area formed from the water-direction regulating surface and theouter wall surface of the front-core nozzle. When the steam parameter of a user is changed, the purpose of continuous and dynamic regulation is achieved under the condition that the operation of a system is not stopped.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and mainly relates to a hot water type dynamic regulation steam-water direct mixing heat exchanger. Background technique [0002] The domestic known steam-water direct mixing heat exchanger can only adjust the flow and temperature intermittently. When the heat load of the heat exchanger changes, or the parameters of steam and supply and return water change and the system affects the normal operation, it cannot be adjusted immediately. Cause the water temperature fluctuation range is too large, the rate of change is too fast. If adjustment is required, the current method is to stop the system, disassemble the equipment as a whole, and adjust the internal structure of the product to meet the requirements of use. Even when the thermal load or operating parameters change slightly, it is impossible to continuously adjust the state of the mixture under a certain influent flow rate, so that the s...

Problems solved by technology

Even when there are slight changes in heat load or operating parameters, it is impossible to continuously adjust the mixture state under a certain influent flow rate, so that the system operates in a non-optimal operating state, reducing heat transfer efficiency and operating safety
