Abstract
The invention relates to a plate type heat exchanger comprising upper and lower heat exchanging plate sheets (1), wherein the heat exchanging plate sheets (1) have anomalous surfaces, the edges of theupper and lower heat exchanging plate sheets are sealed, a devious long channel is formed between the upper and lower heat exchanging plate sheets, and both ends of the channel are provided with a water inlet port (2) and a water outlet port (3). Owing to the design of the heat exchanging plate sheets in the anomalous surface shapes, the length of a water channel is greatly increased, and the heat exchange efficiency of the heat exchanger is improved. The plate type heat exchanger can be widely used for recovering afterheat of waste water or similar large-area waste water and gas dischargingoccasions of waste oil, waste gas, liquid chemical raw materials, and the like.
Description
Affiliated technical field
The present invention relates to a kind of plate heat exchange unit, in particular for the heat-exchangers of the plate type of waste water residual heat recovery.
Background technology
At present, known heat-exchangers of the plate type combines by the multi-disc heat exchange plate, and stamps out complicated emboss pit on heat exchange plate, after the assembling of multi-disc plate, its emboss pit forms the passage of two or more sealings, the heat exchange that fluid does not directly contact in these closed channels respectively.What traditional heat exchanger adopted all is square plate, and individual layer heat exchanger heat exchange efficiency is low, often needs to adopt multi-disc to be combined into the heat exchange unit, just can reach higher exchange efficiency.
Simultaneously, because traditional heat-exchangers of the plate type carries out the pipe method that the fluid access way of heat exchange all adopts emboss pit to form, need just can enter heat exchanger for large tracts of land waste discharge (as shower waste water such as publilc baths, showers), caused scattering and disappearing of heat in the collection process through after the wastewater collection system.And, if the waste water dirt is more, more be easy to generate the heat exchanger clogging, therefore, traditional heat-exchangers of the plate type can't directly apply to the bigger shower waste waste heat recovery occasion of pollution basically.
Summary of the invention
For overcoming the deficiency that existing heat-exchangers of the plate type individual layer heat exchange efficiency is low and can not be directly used in large tracts of land waste discharge waste gas aspect, the invention provides a kind of heat-exchangers of the plate type, this heat exchanger is designed to two-dimensional helical shape, S shape, W shape or other shaped faces with heat exchange plate, after the edge sealing of heat exchange plate, internal voids between the plate has formed aquaporin in the plate, and the plate outer surface becomes waste water tunnel.Aquaporin stream in the clean running water slave plate, and pollutant effluents produces heat exchange from the appearance surface current of plate with running water.Realized the running water heat exchange of aquaporin in large-area shower waste and the plate, save wastewater collection system, reduced the lost process of heat, avoided heat exchanger dirt clogging, and cleaned easy to use.Simultaneously,, prolonged heat exchanging process, increased heat exchanger effectiveness greatly because the special construction of shaped face has formed circuitous water channel.
The technical solution adopted for the present invention to solve the technical problems is: the two boards sheet all is designed to identical shaped two-dimensional helical shape, S shape, W shape or other shaped faces, after the plate edge seals by welding, riveted joint, packing ring or other modes up and down, space between the plate can form tortuous circuitous aquaporin up and down, and the aquaporin two ends are provided with into water port and water outlet port.Running water flows in circuitous aquaporin and the shower waste of the heat exchange plate outer surface of flowing through carries out the waste heat exchange, and then enters in the heater inleting pipe road, perhaps as other hot water purposes, reaches the purpose of waste heat recovery.
The invention has the beneficial effects as follows: at the characteristics of shower waste heat exchange, designed unique plate shape, after the edge sealing, the circuitous aquaporin that forms between the plate, increase the water route length of running water greatly, made cold water to carry out heat exchange with shower waste more fully.Design tongue, increased heat exchange area, aggravated the turbulent flow of running water, reduced the possibility of plate internal flow fouling.In addition, shower waste can flow at the heat exchanger upper surface, and enters by the slit between the heat exchanger shaped face and to flow to lower surface, compares with the mode of having only upper surface to carry out heat exchange merely, has also further improved heat exchanger effectiveness.The shower waste water residual heat that is particularly suitable for environment such as publilc baths, shower reclaims.Also can be used for other waste heat recoveries as similar large tracts of land waste water and gas discharging such as waste oil, waste gas, liquid chemical raw material occasion.Be used for the shower waste waste heat recovery, generally can promote more than inflow temperature 10 degree, the temperature difference of running water and shower waste is big more, energy-saving effect is good more, especially be fit to and the supporting use of instant electric water heater, solve the power bottleneck of instant electric water heater when using winter, can promote the development in instant electric water heater market greatly.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further set forth, need to prove, the present invention not only comprises following examples, comprises that also other are various by after the edge sealing, can reach other shaped face structures that prolong the heat exchange water passage length.
Fig. 1 is the heat converter structure figure that the linear plate of two-dimensional helical constitutes
Fig. 2 is the heat converter structure figure that the spiral yarn shaped plate in two dimension side constitutes
Fig. 3 is the heat converter structure figure that S shape plate constitutes
Fig. 4 is the heat converter structure figure that the W-shaped plate sheet constitutes
Fig. 5 is the heat converter structure figure that another kind of Special-Shaped Surface plate constitutes
1. heat exchange plates among the figure, 2. water inlet port, 3. water outlet port, 4. tongue.
The specific embodiment
In Fig. 1, running water cold water enters in the heat exchanger that two heat exchange plates (1) constitute by water inlet port (2), through circuitous water channel, carries out after the heat exchange with the shower waste of the heat exchange plate of flowing through (1) outer surface, temperature is improved, and flows out from water outlet port (3)., the water that flows out reaches the purpose of saving combustion gas or electric energy if entering water heater, and also can be directly as other purposes.Through the test simulation analysis, if the present invention is used to improve the inflow temperature of water heater, then high energy is saved combustion gas or electric energy about 40%.
Simultaneously, through analysis of experiments, the clearance distance of heat exchange plate (1) can satisfy the traffic requirement of shower for the 0.5-3 millimeter up and down, and can reach heat exchange effect preferably.Heat exchange plate (1) needs to adopt 304 good corrosion resistant plates of corrosion resistance, thickness is lower than 0.3 millimeter then water pressure resistance undercapacity, the heat exchange plate metaboly takes place in the use easily, and thickness is above 1.5 millimeters, then heat exchanger effectiveness will reduce greatly, the energy-saving effect of influence invention.For guaranteeing that good heat exchange effect satisfies the pressure request of anti-the running water again, thickness is that 0.4 millimeter 304 corrosion resistant plates can reach an effect preferably.
