Description
Technical field：
The utility model is related to a kind of vortex flow passage type sewage heat exchangers.
Background technology：
All containing very valuable thermal energy in industrial wastewater, but since these waste components are extremely complex, containing various
Pollutant, the runner of the conventional heat exchanger used in UTILIZATION OF VESIDUAL HEAT IN are very easy to block, will be complete even with 1-2 days
It blocks, it can not long-time service.In addition, as steel industry, paper industry, beverage industry, sugar industry, bio-fuel industry etc. exist
Since viscosity itself is very high containing fiber, particle or fluid in fluid in the heat transfer process of technique productions, heat exchange is easy to cause
The blocking that device flows to.Therefore heat exchanger is shorter usually using the service life, and maintenance and repair is costly, so as to cause the utilization of thermal energy
Cost is higher.
Utility model content：
The utility model provides a kind of vortex flow passage type sewage heat exchanger, it is reasonable in design, fiber in fluid,
Particle will not be sticky on the inner wall of heat exchanger, ensure that fluid is capable of the exchange that smooth outflow carries out thermal energy in heat exchanger,
The service life of heat exchanger is extended, reduces maintenance and repair expense, the utilization cost of thermal energy is reduced, solves the prior art
Present in problem.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of vortex flow passage type sewage heat exchanger, including heat exchanger shell, be equipped in heat exchanger shell tube side runner and
Shell-side flow path, the tube side runner are several vortex heat exchange runners being distributed in heat exchanger shell, all vortexs
One end of formula heat exchange runner is connected with the sewage inlet of heat exchanger, and the other end is connected with the sewage outlet of heat exchanger
It is logical；The shell-side flow path is distributed between the vortex heat exchange runner in heat exchanger shell, one end of shell-side flow path and water purification into
The mouth of a river is connected, and the other end is connected with water purification water outlet.
The vortex heat exchange runner includes being spaced several connected vortex tubes and several Karman vortex street pipes, institute successively
It is the tube body being connected between the vortex tube of both ends to state Karman vortex street pipe, several hydrodynamic forms are equipped at intervals in the inside of tube body.
Using the above structure, fiber, particle in fluid will not be sticky on the inner wall of heat exchanger, ensure for the utility model
Fluid is capable of the exchange that smooth outflow carries out thermal energy in heat exchanger, extends the service life of heat exchanger, reduces maintenance
Maintenance cost reduces the utilization cost of thermal energy.

Fig. 2 is the structure diagram of the vortex heat exchange runner of the utility model.
Fig. 3 is fluid state figure in the vortex tube of the utility model.
Fig. 4 is the Karman vortex street tube fluid state diagram of the utility model.
In figure, 1, heat exchanger shell, 2, vortex heat exchange runner, 3, vortex tube, 4, Karman vortex street pipe, 5, hydrodynamic form.
Specific embodiment：
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with new.
As shown in figs. 1-4, a kind of vortex flow passage type sewage heat exchanger, including heat exchanger shell 1, in heat exchanger shell 1
Interior to be equipped with tube side runner and shell-side flow path, the tube side runner is several vortexes being distributed in heat exchanger shell 1
Heat exchange runner 2, one end of all vortex heat exchange runners 2 are connected with the sewage inlet of heat exchanger, and the other end is with changing
The sewage outlet of hot device is connected；The shell-side flow path is distributed between the vortex heat exchange runner in heat exchanger shell, shell
One end of Cheng Liudao is connected with water purification water inlet, and the other end is connected with water purification water outlet.
The vortex heat exchange runner includes being spaced several connected vortex tubes 3 and several Karman vortex street pipes 4 successively,
The Karman vortex street pipe 4 is the tube body being connected between both ends vortex tube 3, several hydrodynamic forms are equipped at intervals in the inside of tube body
5。
The vortex tube 3 is to appoint to take small closed curve in rotational field, crosses every bit on the closed curve and makees vortex filament, this
The tubular surface that a little vortex filaments are formed claims vortex tube, full of the fluid to rotate in vortex tube.
The operation principle of the Karman vortex street pipe 4 is：There are several hydrodynamic forms 5, fluid in Karman vortex street pipe 4 to pass through
It is present with Karman vortex street phenomenon when crossing hydrodynamic form 5,5 both sides of hydrodynamic form can periodically occur that direction of rotation is opposite, queueing discipline
Biserial line vortex.
In heat transfer process is carried out, sewage is entered by sewage inlet in tube side runner, is flowed through after tube side runner from dirt
Water water outlet is discharged, and water purification enters shell-side flow path by water purification water inlet, then by discharging with water purification water outlet, completes to change
Heat.After sewage inlet pipe journey runner, when by vortex tube 3, due to the characteristic of vortex tube 3 so that be full of and do in vortex tube 3
The wastewater fluids of rotary motion form whirlpool beam, can generate larger velocity gradient, are vortexed so that the movement locus of fluid occurs
Variation, increases the velocity gradient between laminar flow, can so that the particle in current rotates repeatedly around central shaft and rotation, particle exist
Fierce collision, effectively quickly spreads in particle under the active force of different directions, the graininess dregs in sewage without being adhered to
In runner；When sewage flows through Karman vortex street pipe 4, due to the influence of Karman vortex street phenomenon so that by the sewage meeting of hydrodynamic form
Periodically there is biserial line vortex in the both sides of hydrodynamic form, be further exacerbated by the diffusion and collision of the impurity particle in current,
It avoids and is attached in runner, meanwhile, current pass through multiple vortex accelerating function so that the higher wastewater fluids flowing of viscosity itself
Property greatly enhances.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within the guarantor of the utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
