Description

Multistage boosting energy-saving heat exchanger

Technical field

The present invention relates to a kind of heat-exchanger rig.

Background technology

Common heat exchanger has dividing wall type heat exchanger and direct contact heat exchanger in the heat-mass exchange equipment; Wherein, dividing wall type heat exchanger is used in heating system at most, in heating system; Dividing wall type heat exchanger exists following problem demanding prompt solution in application: 1, high temperature fluid and cryogen are carried out heat exchange through heat-transfer surface; Two side liquids are isolated by heat-transfer surface, have wasted the kinetic energy and the pressure energy of hot operation fluid, and the circulation of cryogen need rely on electric pump power consumption operation; 2, the incrustation scale of heat-transfer surface both sides produces thermal resistance, and heat exchange efficiency is reduced, and has increased consumption of heat energy.

In direct contact heat exchanger; Representative is steam jet ejector and water-water jet; Though these two kinds of direct contact heat exchangers have solved the problems referred to above of dividing wall type heat exchanger; But the direct contact heat exchanger of this class formation exists following shortcoming, that is: deficiencies such as lift is little, vibration is big, noise is big, job insecurity, the variable working condition adaptive capacity is poor, the scope of application is little.

Summary of the invention:

For solving the deficiency of prior art in the heat-mass exchange equipment; The present invention provides a kind of multistage boosting energy-saving heat exchanger, to solve problems such as existing direct contact heat exchanger lift is little, vibration is big, noise is big, service behaviour is unstable, the variable working condition adaptive capacity is poor, the scope of application is little.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of multistage boosting energy-saving heat exchanger adopts self adaptation to regulate nozzle and multistage pressurized construction, it is characterized in that; One level adaptation is regulated nozzle, one-level heat-exchanging chamber, secondary jet pipe, secondary heat-exchanging chamber, three grades of heat-exchanging chambers, the coaxial successively connection in pumping chamber, the dead in line of the axis of its axis and heat exchanger shell and self adaptation conditioning chamber; The outer surface of regulating nozzle at a level adaptation has the two seals ring, and the sealing ring is placed in the inner annular groove of heat exchanger shell, and a level adaptation is regulated nozzle can do the front and back displacement along axis in the two seals ring; The one-level heat-exchanging chamber places a level adaptation to regulate after the nozzle; Regulate nozzle threads with a level adaptation and be connected, the outer surface of one-level heat-exchanging chamber constitutes the overcritical circulation nozzle of secondary with the inner surface of secondary jet pipe, and the secondary heat-exchanging chamber places after the secondary jet pipe; Be connected with the secondary spout threads; Three grades of heat-exchanging chambers and pumping chamber form one, place after the secondary heat-exchanging chamber, are threaded with the secondary heat-exchanging chamber.

The inlet front end that one level adaptation is regulated nozzle connects the self adaptation conditioning chamber; The self adaptation conditioning chamber is made up of the thrust spring and the tension spring at adjusting rod, spring base and spring base two ends; A spring base and a level adaptation are regulated nozzle and are fused, and the elastic force of rotary regulating lever scalable two springs is when the pressure before a level adaptation is regulated jet expansion changes or its back pressure changes; The capital changes the elastic force of spring base both sides spring; Thereby making the outlet section of level adaptation adjusting nozzle and the distance between the one-level heat-exchanging chamber inlet section is larynx mouth distance, changes, and has stablized one-level lift and flow.

One-level hot operation fluid intake pipe and secondary hot operation fluid intake pipe are positioned at the same side of heat exchanger shell; A side opposite with it is one-level cryogen inlet tube and secondary, three grade low-temp fluid intake pipes, and the axis of four high temperature, cryogen inlet tube and the axis of heat exchanger shell are in same plane.

Adopt good effect of the present invention: cold fluid and hot fluid directly mixes, and heat exchange is abundant, has reduced heat-energy losses; One level adaptation is regulated nozzle and is regulated axial displacement automatically with the variation of working fluid pressure, has stablized one-level lift and flow, has reduced vibration and noise, and equipment is operated steadily, reliably; Owing to increased the overcritical circulation nozzle of secondary, improved the lift and the flow of this heat exchanger, strengthened the water pump function of this heat exchanger, water pump and heat exchanger are integrated in one; Owing to increased secondary heat-exchanging chamber and three grades of heat-exchanging chambers, expanded the variable working condition adaptive capacity of multistage boosting energy-saving heat exchanger, the scope of application is wider.
