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

[0001] technical field [0002] The invention belongs to the technical field of heat exchange, and mainly relates to a hot water type dynamic adjustment type steam-water direct mixing type heat exchanger. Background technique [0003] The well-known steam-water direct mixing heat exchanger in China can only adjust the flow rate and temperature intermittently. When the heat load of the heat exchanger changes, or the parameters of steam and water supply and return change, the system cannot be adjusted immediately and the normal operation is affected. Causes the water temperature to fluctuate too much and change too fast. If adjustment is required, the current method is to stop the operation of the system, disassemble the equipment as a whole, and adjust the internal structure of the product to meet the requirements of use. Even when there is a slight change in heat load or operating parameters, it is impossible to continuously adjust the state of the mixture under a certain i...
