Detailed description of the invention
A kind of spiral heat exchanger with defencive function as shown in Figure 1, Figure 2 and Figure 3; comprise heat flux plates 2, cold flow plate 1; heat flux plates 2 is connected with cold flow plate 1 spiral winding; it is characterized in that: described heat flux plates 2 also has relief hole 18; relief hole 18 is built with pressure relief device; described pressure relief device is made up of two spools 17, valve cylinder 16 and spring 15; valve cylinder 16 is contained in relief hole 18; two spools 17 are relatively positioned over the two ends in valve cylinder 16, and two spools 17 are connected by spring 15.Conduct heat to heat flux plates 2 and cold flow plate 1 transportation of substances during work simultaneously, because in heat flux plates 2, the temperature of material is higher, pressure in it is also just higher, will produce blast, cause unnecessary injury to machine and other people when its pressure exceedes the critical value that self structure bears.This structure by setting up 2 relief holes 18 in heat flux plates 2; relief hole 18 is built with the pressure relief device be made up of two spools 17, valve cylinder 16 and spring 15; when pressure is excessive; pressure can promote spring 15; gases at high pressure or liquid will be discharged from the space of spool 17 with valve cylinder 16; reduce the pressure in heat flux plates 2, self structure is played a protective role.Heat flux plates 2 of the present invention and cold flow plate 1 adopt spiral winding to be connected to add the contact area of hot and cold of heat exchanger, improve the operating efficiency of heat exchanger.
The two ends of cold flow plate 1 are as shown in Figure 1 connected with the first circulation pipe 3, first circulation pipe 3 and are provided with condenser 8, are also provided with heat power collection generator between the outlet of cold flow plate 1 and condenser 8.Described heat power collection generator forms by being connected in the heat collector 10 of the first circulation pipe 3, the heat exchanger 9 be connected with heat collector 10, heat generator 5 and circulating pump 7; Heat exchanger 9, heat generator 5 are connected by the second circulation pipe 6 successively with circulating pump 7.Medium in cold flow plate 1 has higher temperature after completing heat transfer, if just can not recycle to medium cooling, greatly wastes resource.So the present invention is provided with condenser 8 on the first circulation pipe 3, this design is to recycle to medium cooling.If temperature wastes and can cause greatly energy waste in the medium in cold flow plate 1, so had additional heat power collection generator in the present invention between the outlet and condenser 8 of cold flow plate 1, the heat of medium in cold flow plate is gathered by heat collector 10, these heats are passed to the medium of the second circulation pipe 6 by heat exchanger 9, the medium of the second circulation pipe 6 generates electricity through heat generator 5 at the flows by action of circulating pump 7, finally flow back into again heat exchanger 9, complete the regeneration of the energy.
The two ends of heat flux plates 2 as shown in Figure 1 are also connected with return duct 4, and return duct 4 is provided with gauge tap 13, and gauge tap 13 is connected with storage tank 12 with thermometer 11 respectively.This design is in order to ensure needing the temperature of cooling material to meet the requirements, after the temperature recording material when thermometer 11 meets the demands, gauge tap 13 can mass emissions in storage tank 12, when the temperature of material is undesirable, material again flow in heat flux plates 2 by return duct 4 under the effect of gauge tap 13, carries out heat transfer again.
Filter 14 is also equipped with in the porch of heat flux plates 2 as shown in Figure 1, and described filter 14 is liquid filter or gas dust remover.This design is used to remove the impurity being delivered into material in heat flux plates, prevents the generation of channel blockage; Need likely to there is a large amount of impurity in the liquid of cooling or gas, the blocking forming passage is easy to when the unification of these impurity is deposited in a place, not only reduce operating efficiency, and easily cause danger, so this design is very necessary, not only to purify material, but also served the effect that Accident prevention occurs.
In sum the present invention have structure simple, be easy to the advantages such as manufacture, Environmental Safety, heat transfer rate be fast, there is the good market competitiveness.
