Abstract
The utility model relates to a recovering device for waste water heat, which is used for recovering the heat of the waste water discharged from various production and technology and is composed of an eccentric wheel, a swing link, a heat exchanger, etc., wherein, the heat exchanger can move to-and-fro in the flowing medium through the swing link mechanism to intensify the heat transfer between a pipe wall and the fluid. The utility model has the advantages of simple structure, high thermal efficiency, less maintenance work, etc. and has strong self-cleaning capacity to prevent the adhesion of the dirt and the block of the foreign matter; meanwhile, because the waste liquid can flow freely to carry out heat exchange, the water pump equipment and the electric energy are saved, and the utility model is suitable to be used for recovering waste heat from various kinds of waste liquid discharged by the weaving and dyeing industry, the light industry, the chemical industry, the boilers, etc.
Description
The utility model relates to a kind of waste-heat recovery device that all kinds production, technology give off the spent hot water that is used to reclaim.
The heat exchanger that generally is used for the waste liquid waste heat recovery has multitube, votator.Common in the multi tube heat exchanger have shell-and-tube exchanger, though this heat exchanger simple structure, cost are low, heat transfer efficiency is lower, and its Coefficient K value is 233～1163W/m
2℃, even and waste liquid in the shell flows outside, also stopped up by impurity easily, make troubles to operational management; Though heat-exchangers of the plate type belongs to efficient heat exchanger, its K value is 2326～5814W/m
2℃, but because its special internal structure involves great expense, one-time investment is big, and inner also have leak may, simultaneously because water stream channel is narrow, when handling the bigger waste liquid of impure amount, blocked possibility is then arranged, though it can integral demounting, maintenance is still inconvenient; Spiral heat exchanger is derived from by heat-exchangers of the plate type, and heat transfer efficiency is higher, and the K value is 1163～2326W/m
2℃, but it can not dismantle, and therefore, does not fit into the more situation of waste liquid impurity.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of spent hot water's waste-heat recovery device that merges above three's advantage is provided.
The utility model is achieved by the following scheme: by swing-bar mechanism, heat exchanger is moved back and forth in the medium that flows, thereby strengthened the heat transfer between tube wall and fluid greatly.
The utlity model has simple in structurely, (the K value is 2400W/m to the heat transfer efficiency height
2℃), advantages such as maintenance load is few itself have self-purification capacity, and the state that can freely flow because of waste liquid are carried out heat exchange, thereby save the pump equipment and the electric energy of this side, be suitable for the waste heat recovery of polytype waste liquids such as textile printing and dyeing, light industry, chemical industry, boiler blow-off.
Below in conjunction with accompanying drawing the utility model is carried out enumeration:
Accompanying drawing is the utility model schematic diagram of structure.
See accompanying drawing, the utility model is by eccentric wheel (1), fork (2), and connecting rod (3), heat exchanger (4), flexible pipe (5), waste liquid tank (6) is formed.Fork (2) off-centre is fixed on the eccentric wheel (1), and fork (2) one ends are connected with connecting rod (3) hinge, and heat exchanger (4) is fixed on connecting rod (3) one ends, and directly is seated in the waste liquid tank (6).
When using the utility model, pass through motor, transmission mechanisms such as belt pulley drive eccentric wheel (1) and rotate, driving the eccentric fork of fixing on it (2) swings around an end of fork (2), make it become the reciprocating motion of connecting rod (3), the final heat exchanger (4) that drives does reciprocating linear motion in waste liquid tank (6), one from the flexible pipe (5) of heat exchanger (4) is injected clear water, the pipe outside of heat exchanger (4) directly contacts with waste liquid in waste liquid tank (6) carries out heat exchange, not only self is reciprocating because of the utility model, and waste liquid also flows in waste liquid tank (6), make the turbulence level of the inside and outside side liquid of pipe be improved, especially in the pipe outside, just can enter the turbulent region with less Reynolds number, thereby strengthen the heat transfer between tube wall and fluid widely.And in heat exchange, heat exchanger (4) is to be placed directly in the waste liquid, and waste liquid need not be a pressure flow, can be freely to flow, and its advantage is: one can economize the power of a side water pump; Two can reduce intermediate links in circulation, and have reduced heat loss; Three because heat exchanger (4) moves in waste liquid, makes that impurity, the suspension in the waste liquid is difficult to attached on the heat-transfer area.Played the effect of self-cleaning; Four fundamental rules are convenient to maintenance management outside because heat-exchange surface is exposed, and heated clear water flows out from flexible pipe (5) other end in heat exchanging process.
The heat exchanger (4) that links to each other with connecting rod (3) can be made the light pipe tube bank, long bundle in ellipse garden or board-like heat-exchange surface.
The extent of corrosion that the material of heat exchanger is looked waste liquid can adopt general carbon steel, stainless steel or other corresponding anti-corrosion material.
Claims (2)
1, spent hot water's waste-heat recovery device, comprise eccentric wheel (1), fork (2), connecting rod (3), heat exchanger (4), flexible pipe (5), waste liquid tank (6), it is characterized in that fork (2) off-centre is fixed on the eccentric wheel (1), fork (2) one ends are connected with connecting rod (3) hinge, heat exchanger (4) is fixed on an end of connecting rod (3), and directly is seated in the waste liquid tank (6).
2, spent hot water's waste-heat recovery device according to claim 1 is characterized in that: the heat exchanger (4) that links to each other with connecting rod (3) can be made the light pipe tube bank, long bundle in ellipse garden or board-like heat-exchange surface.
