Problems solved by technology

Even when there is a slight change in the heat load or operating parameters, it is impossible to continuously adjust the mixture state under a certain influent flow, so that the system operates in a non-optimal operating state, which reduces the heat exchange efficiency and operational safety.

Abstract

The invention belongs to a heating-type dynamically adjustable steam-water directly mixing heat exchange device comprising a front three-way valve (1), a front core (2), a middle three-way valve (3), a middle core (4), a rear two-way valve (5), a temperature sensor, an electric operator and a controller, wherein the front core (2) is coaxially arranged in the middle three-way valve (3); and the middle core (4) is embedded between the middle three-way valve (3) and the rear two-way valve (5). The heat exchange device is characterized in that an adjusting device (7) is arranged between the front core and the middle core, can move forwards and backwards horizontally in the axial direction under the drive of the electric operator, and comprises a water direction adjusting surface (14) and a steam direction adjusting surface (15); the steam flow can be controlled by adjusting the variable sectional area formed by the steam direction adjusting surface and the inner wall surface of a front core spray nozzle; and the water inflow can be controlled by adjusting the area formed by the water direction adjusting surface and the outer wall surface of the front core spray nozzle. When the steam parameter of a user changes, the purpose of continuous dynamic adjustment can be achieved under the condition that the operation of the system is not stopped.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and mainly relates to a heating 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 heat 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 system...
