The present invention relates to a heat exchanger which can be sued for heat transferring in the industrial fields of petroleum, chemical engineering, energy sources, etc. The heat exchanger is vertical, and the basic structure of the heat exchanger is consistent with common vertical heat exchangers; the present invention is composed of an upper pipe box, a lower pipe box, a heat exchange pipe bundle and a shell body and is characterized in that a hydraulic cyclone is arranged in the upper pipe box which is provided with a spiral channel and a flow guiding plate; an outlet of a heat exchange pipe is connected to the inlet end of the spiral channel; the outlet end of the spiral channel is connected with an inlet of the flow guiding plate; the outlet end of the flow guiding plate is connected to a barrel body part of the hydraulic cyclone; a uniform plate is arranged in the lower pipe box; an umbrella-shaped baffle plate is arranged below the uniform plate; center desilting pipes are arranged at the part from the lower outlet of the hydraulic cyclone to the vicinity of the upper position of the umbrella-shaped baffle plate; the whole heat exchanger is sealed by a flat cover and a lower sealing end and is supported by a hanging support. The present invention has the advantages of strengthening heat transfer, compact structure and high stability.
Description
Technical field
The invention provides a kind of novel heat exchanger with compacting internal circulating fluidized bed.This heat exchanger can not only augmentation of heat transfer, and its compact conformation, good stability.Can be used for oil, chemical industry, the heat transfer of industrial circles such as the energy is used.
Background technology
Its structure of traditional fluid-bed heat exchanger is formed and is mainly comprised inducer, outlet section, heat-exchanging tube bundle and housing four parts.The heat exchanger inducer is made up of liquid-inlet section and solid particulate distributions section.The solids distribution plate is between inlet tube and grain fluidized section.Liquid and solid particle mix that fluidisation is laggard goes into heat-exchanging tube bundle and thermal medium generation energy exchange, are finally discharged by the port of export.The shortcoming of this structure is to be difficult to realize the normal circulation of solid particle.So developed a kind of recirculating fluidized bed heat exchanger, behind cyclone hydraulic separators, realize Separation of Solid and Liquid from fluid and solid particle that upper tube box flows out, solid particle turns back in the lower tube box through circulation pipe and recycles once more.This structure is formed and is also had weak point, mainly is the asymmetry of structure, easily brings the instability of operation and the problem of particle entrainment.Simultaneously, owing to the cyclone hydraulic separators device circulates in the heat exchanger outside, brought energy loss.On financial cost, this heat exchanger flow process complexity, bulky, cost is higher.
Summary of the invention
The present invention seeks to overcome the shortcoming of prior art, a kind of physical dimension compactness is provided, heat exchange efficiency height, the fluid-bed heat exchanger that operational stability is good.This structure can solve that original device operating condition is narrow, the shortcoming of fluctuation of service and thermal loss, the position of reasonable Arrangement upper perforated plate and lower perforated plate, structures such as hydrocyclone, deflector, helical duct and uniform board applied in any combination have first improved the stability and the energy utilization ratio of operation effectively, umbrella-shaped baffle has then effectively improved the problem of particle entrainment, thereby has enlarged the operating condition scope of heat exchanger.
This heat exchanger is vertical, its basic structure is consistent with common vertical heat exchanger, form by upper and lower bobbin carriage, heat-exchanging tube bundle and housing, it is characterized in that device has hydrocyclone in upper tube box, be furnished with helical duct and deflector simultaneously, the heat exchanger tube outlet is connected to the helical duct arrival end, and the helical duct port of export links to each other with the deflector arrival end, and the deflector port of export then is connected to the shell portion of hydrocyclone simultaneously.Lower tube box is provided with uniform board, under the uniform board umbrella-shaped baffle is arranged.Desilting pipe installation position, center exports down until near the umbrella-shaped baffle top from hydrocyclone.Fluid mixes fully through uniform board and solid particle that fluidisation is laggard goes into heat exchanger tube, fully the pre-supination of helical duct of flowing through of the liquid-solid two-phase of heat exchange is separated by hydrocyclone, solid particle is deposited in the lower tube box along center desilting pipe and recycles, and liquid is then discharged by top exit.Whole heat exchanger is sealed by flat cover and low head, and is supported by hanging support.
Advantage of the present invention is: aspect structural configuration, consider the characteristics of external liquid-solid separator, change liquid-solid separator into built-in hydrocyclone, thereby reduced energy loss; Also make simultaneously the integral device compactness that becomes, improved the stability of heat exchanger in running, umbrella-shaped baffle has then improved the problem of particle entrainment.Liquid-solid separator adopts hydrocyclone, recycles solid particle, and economy is environmental protection again.

Specific implementation
Further this heat exchanger is described below in conjunction with structural representation.
In the bottom of heat exchanger, fluid enters from bottom to top from fluid intake (9) and flows, and thermal medium enters heat exchanger shell (12) from thermal medium import (4), and solid particle is then entered by solid particle import department (10).Fluid fully mixes with solid particle through uniform board (21), make numerous solid particle keep stable fluidized state after, enter in the heat exchanger tube (23).Solid particles flowing heat exchanging organ pipe inwall on the one hand plays the dirt effect of washing of washing away.Constantly destroy the boundary layer on the other hand, make fluid under low flow velocity, also can keep turbulent flow, strengthened rate of heat transfer greatly, and the particle that contact with wall transmits energy to turbosphere, be equivalent to form a mobile transmission extended surface, help heat transfer.Adopt hydrocyclone (16) that liquid-solid mixture is separated in the upper tube box (3), hydrocyclone shell portion welding deflector (14).Fully the liquid-solid mixture of heat exchange flows out heat exchanger tube near upper perforated plate (17), is introduced into spiral shell type passage (15) and prewhirls, and makes liquid-solid mixture have certain kinetic energy, afterwards in deflector enters hydrocyclone.After liquid-solid mixture entered in the hydrocyclone, solid particle kinetic energy was almost constant, and speed is also constant, but along with the minimizing of cyclone radius, its angular speed increases, and centrifugal force also increases thereupon, thereby realizes liquid-solid separation in the effect of centrifugal force field.Than vortex outside solid particle forms under action of centrifugal force greatly, flow to the wall of hydrocyclone, and to dirty.Flow back to through center sand sediment pipe (18) in the lower tube box (7) of heat exchanger, recycle.Liquid phase after the Separation of Solid and Liquid is outflow heat exchanger behind top overflow pipe fluid issuing (1).Thermal medium after the heat exchange then flows out housing by near the outlet of the thermal medium the lower perforated plate (20) (11), and the condensate liquid that is produced is then also finally discharged by discharging tube (6) through deflection plate (19).Center desilting pipe bottom is provided with umbrella-shaped baffle (22) in addition, moves upward to prevent particle, thereby has avoided the problem of particle entrainment.Whole heat exchanger is sealed by flat cover (2) and low head (8), and is supported by hanging support (5).
