Abstract

The invention provides a heat storage device which can solve the problems that at present, when a user directly purchases and uses hot water, water resources are wasted, and heat energy is lost. The heat storage device comprises a sealed bin and a heat exchange device. The sealed bin is filled with a heat storage material. The heat exchange device is buried in the heat storage material. A water inlet pipe and a water outlet pipe are arranged on the sealed bin and connected with the heat exchange device.

Description

Regenerative apparatus

Technical field

The present invention relates to central heating technical field, be specially regenerative apparatus.

Background technology

Factory in daily productive life, hotel, school all needs centralizedly supply hot water, along with the development in city, arrange pressure boiler in densely inhabited district to carry out centralizedly supply hot water and often there is many potential safety hazards, and directly carry hot water to need carry out a large amount of pipe network laying project by transmission pipeline network to user by Thermal Plant thus cause pipe network to lay the high problem of cost, therefore increasing unit adopts the mode directly to Thermal Plant purchase hot water to solve the problem of hot water supply, for routine use in the attemperater normally by special delivery car hot water being delivered to applying unit by Thermal Plant, but also there is following problem in it: the heat-insulating property of attemperater is lower, when the hot water in attemperater did not use the same day, user cannot carry out heating recycling to the water do not used, therefore the hot water that the same day did not often use by user is discharged, thus cause a large amount of wastes of water resource, meanwhile, delivery car is poor to the insulating power of hot water in transportation, causes hot water a large amount of heat energy in course of conveying to leak, thus cannot ensure the serviceability temperature of user's hot water.

Summary of the invention

For the problems referred to above, the invention provides regenerative apparatus, its can solve existing user directly buy exist in hot water use procedure water resource waste, heat-energy losses problem.

Regenerative apparatus, it is characterized in that: it comprises sealed cabin body and heat-exchanger rig, closely knitly in described sealed cabin body be filled with heat-storing material, described heat-exchanger rig is embedded in described heat-storing material, described sealed cabin body is provided with water inlet pipe and outlet pipe, and described water inlet pipe, outlet pipe are connected with described heat-exchanger rig respectively.

It is further characterized in that:

Described heat-exchanger rig comprises heat exchange pipeline, described heat exchange pipeline is arranged has two groups at least, described at least two group heat exchange pipelines are embedded in described heat-storing material, described water inlet pipe, outlet pipe correspondence is arranged has two groups at least, the entrance point of described two groups of heat exchange pipelines, the port of export respectively with corresponding water inlet pipe, outlet pipe UNICOM.

Further, described heat-exchanger rig also comprises some heat exchange fins, and described some heat exchange fins are parallel to be embedded in described heat-storing material, and described heat exchange pipeline moves towards to arrange along described heat exchange fin and is attached to described heat exchange fin surface;

Described heat-storing material is expansion system≤8% of phase change heat storage material, described phase change heat storage material;

Described phase change heat storage material is preferably paraffin.

The beneficial effect of regenerative apparatus of the present invention is: the heat-storing material loaded in accumulation of heat storehouse effectively can absorb storing heat, and by heat-exchanger rig being embedded in the heat-storing material in sealed cabin body, and by the heat exchange pipeline in heat-exchanger rig and water inlet pipe, outlet pipe is communicated with, just the heat exchange between heat-storing material and heat-exchanger rig can be realized, thus only need the hot water by Thermal Plant exports to pass in the heat-exchanger rig of regenerative apparatus in actual use, namely heat energy in hot water to be absorbed by heat-storing material by heat-exchanger rig and preserve, as long as also cold water is passed in the heat-exchanger rig of regenerative apparatus when user uses, cold water just can realize the instant heating to cold water by heat-exchanger rig and the heat-storing material generation heat exchange storing heat energy, thus it has the feature of instant heating, therefore effectively can avoid the waste of water resource, and due to the heat storage capacity of heat-storing material strong, regenerative apparatus in transit heat loss is little, heat-exchanger rig is made up of heat exchange pipeline and some fins, and heat exchange pipeline attachment is installed on fin surface, can ensure the uniformity of heat exchange efficiency and heat exchange, guarantee stable in outlet water temperature.

Accompanying drawing explanation

Fig. 1 is the structural representation of regenerative apparatus of the present invention;

Fig. 2 is that A that in regenerative apparatus of the present invention, two groups, water inlet pipe side heat exchange pipeline and fin assemble is to schematic diagram.

Detailed description of the invention

See Fig. 1, regenerative apparatus, it comprises sealed cabin body 10 and heat-exchanger rig 20, closely knitly in sealed cabin body 10 be filled with heat-storing material 30, heat-exchanger rig 20 is embedded in heat-storing material 30, and sealed cabin body 10 is provided with water inlet pipe and outlet pipe, and water inlet pipe, outlet pipe are connected with heat-exchanger rig respectively.

Wherein, see Fig. 2, heat-exchanger rig 20 comprises and is embedded in two groups of heat exchange pipelines 21-1,21-2 in heat-storing material 30 and some heat exchange fins 22, the entrance point of heat exchange pipeline 21-1, the port of export respectively with water inlet pipe 50-1, outlet pipe 40-1 UNICOM, the entrance point of heat exchange pipeline 21-2, the port of export respectively with water inlet pipe 50-2, outlet pipe 40-2 UNICOM; Some heat exchange fins 22 are parallel to be embedded in heat-storing material 30, and heat exchange pipeline 21-1,21-2 move towards to arrange along some heat exchange fins 22 and be attached to heat exchange fin 22 surface; Heat-storing material 30 is phase change heat storage material, and expansion system≤8% of phase change heat storage material; Phase change heat storage material is preferably paraffin.

When regenerative apparatus of the present invention uses, first one of them water inlet pipe 50-1 of regenerative apparatus is connected with waste heat pipeline, hot water in waste heat pipeline flows in heat exchange pipeline 21-1 from water inlet pipe 50-1, hot water is by the tube wall of heat exchange pipeline 21-1, fin 22 and phase change heat storage material generation heat exchange in heat exchange pipeline 21-1, and namely phase change heat storage material absorbs also heat energy storage hot water cooling simultaneously and discharge from outlet pipe 40-1; And then regenerative apparatus entirety is transported to user place, cold water pipe is being connected with the water inlet pipe 50-2 of regenerative apparatus, cold water flows in heat exchange pipeline 21-2 from water inlet pipe 50-2, cold water in heat exchange pipeline 21-2 by the phase change heat storage material generation heat exchange of the pipeline of heat exchange pipeline 21-2, fin 22 and heat energy storage, thus the heating realized cold water, the water after heating flows out for user from outlet pipe 40-2 again.

Heat-exchanger rig in the present invention arranges outlet pipe, the water inlet pipe of heat exchange pipeline more than two and correspondence thereof, the heat exchange efficiency of regenerative apparatus and water yield can be improved on the one hand, to meet the actual user demand of user, the heat exchange pipeline of heat absorption can be separated completely with the heat exchange pipeline of heat transmission on the other hand, thus effectively avoid front road remaining hot water to the pollution of user's domestic water, guarantee the water safety of user.
