Summary of the invention
The utility model mainly solves high temperature thermal medium and must get into cooling system and cool off, and the waste problem that a large amount of heats scatter and disappear and cause provides a kind of simple in structure, good effect of heat exchange, cost is low, the life-span is long, free of contamination thermal energy recycle device.
The utility model is conceived to the problems referred to above and mainly is able to solve through subordinate's technical scheme:
A kind of thermal energy recycle device; It comprises temperature-sensing valve, heat exchanger, check valve, water pump, circulation attemperater; Temperature-sensing valve, heat exchanger, check valve, water pump, circulation attemperater link to each other successively and form a cycle heat exchange loop; It is characterized in that described circulation attemperater outlet other end pipeline is provided with a water pump, the other end of water pump links to each other with check valve, flowmeter, large-scale heat storage water tank respectively and forms the heat exchange hot water passageway.In heat-exchanging loop; Recirculated water constantly flows in the loop under the driving of water pump, all promotes to some extent through heat exchange temperature each time, and temperature also slowly promotes in the circulation attemperater; Until reaching rated temperature; Heat exchange this moment hot water passageway is opened, and the water pump driving through cyclic water tank other end exit is evacuated to large-scale heat storage water tank with finished product hot water; The liquid level finished product hot water passageway that constantly descends when touching low liquid level control point is closed in the circulation attemperater, the moisturizing magnetic valve at circulation attemperater top open and in water tank moisturizing stop moisturizing until reaching high liquid level.State when liquid level reaches initial again in the circulation attemperater, cycle heat exchange loop running continuously slowly heat up recirculated water again, so repeatedly.When water temperature is lower than setting value in the large-scale heat storage water tank; Cyclic water tank moisturizing source becomes by the water in the large-scale heat storage water tank; The path of rising again is opened and is carried out the moisturizing function, when water temperature is higher than setting value in large-scale heat storage water tank, switches to the moisturizing of cyclic water tank top again.When too high and water temperature was on setting value when liquid level in the large-scale heat storage water tank, the liquid level protection started, and system shuts down.System's running is accomplished by electrical control.
As preferably, said temperature-sensing valve is connected with heat exchanger and can keeps stable state to reach the withdrawing fluid temperature according to incoming flow fluid temperature adjustment valve opening, reclaim the heat of high temperature incoming flow liquid simultaneously.
As preferably, described large-scale heat storage water tank is risen again and mouthful is in turn connected to form the path of rising again with magnetic valve, circulation attemperater.
As preferably, be provided with temperature switch in the described large-scale heat storage water tank.
As preferably, described circulation attemperater top is provided with water pipe, and pipeline is provided with moisturizing magnetic valve (7).
As preferably, described heat exchanger is a plate type heat exchanger.
As preferably, described circulation attemperater inside is provided with temperature switch.
As preferably, described cycle heat exchange loop is provided with maintenance and cleans interface.
As preferably, described maintenance is cleaned interface and is provided with stop valve.
As preferably, said water pump is the stainless steel pipes pump.
As preferably, said attemperater is a stainless steel double-layer heat insulation water tank.
As preferably, be provided with liquid-level switch in the said circulation attemperater, liquid-level switch control moisturizing magnetic valve.
As preferably, be provided with liquid-level switch in the described large-scale heat storage water tank.
As preferably, the thermal medium of described heat exchanger is imported and exported and is provided with three stop valves, is communicated with successively to form bypass.
As preferably, be provided with filter between described circulation attemperater and the water circulating pump.
The utility model is simple in structure, good effect of heat exchange, cost is low, the life-span is long, free of contamination thermal energy recycle device.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: as shown in Figure 1.The utility model is a kind of thermal energy recycle device, comprises temperature-sensing valve 1, heat exchanger 2, circulation attemperater 3, large-scale heat storage water tank 4, water pump 5, check valve 6, magnetic valve 7, liquid-level switch 8, temperature switch 9, stop valve 10, flowmeter 11.Wherein temperature-sensing valve 1, heat exchanger 2, check valve 6, water pump 5, circulation attemperater 3 are in turn connected to form a cycle heat exchange loop; Temperature-sensing valve 1 built-in physics temperature-sensing element; Can keep stable state to reach the withdrawing fluid temperature according to incoming flow fluid temperature adjustment valve opening.Other end outlet and water pump 5, check valve 6, the flowmeter 11 of circulation attemperater 2 links to each other successively and forms finished product delivery path.Large-scale heat storage water tank 4 is risen again mouthful and magnetic valve 7, circulation attemperater 3 are in turn connected to form the path of rising again.
The utility model utilizes the thermal source medium of ambient systems to produce low-grade hot water, reaches the effect of heat energy recycle.Thermal medium is discerned taste through temperature-sensing valve 1 earlier before getting into system, opens temperature if heat medium temperature is lower than temperature-sensing valve 1, and then the direct bypassing reflux stream of thermal medium is without heat exchanger 2; Open temperature if heat medium temperature is higher than temperature-sensing valve 1, then thermal medium partly gets into heat exchanger 2, and the mass flow that gets into heat exchanger 2 forms interlock with coming liquid temp, makes back liquid that clearly stable temperature index arranged.Part gets into the hot-fluid of heat exchanger 2 and comes the recirculated water in self circulation heat exchange loop to carry out heat exchange; Under the promotion of water pump 5; Recirculated water in the circulation attemperater constantly obtains heat and obtains rated value in heat exchanger 2, and is sent to large-scale heat storage water tank 4 by water pump 5 and preserves.
When water temperature reached rated value in the circulation attemperater 3, water tank right-hand member water pump 5 brought into operation in finished product delivery to the large-scale heat storage water tank 4; Along with the continuous firing of water pump 5, the liquid level in the cyclic water tank 3 constantly descends, and sets 8 actions of liquid surface level switch until reducing to; This moment, magnetic valve 7 unlatchings and water pump 5 stopped; Obtain moisturizing in the circulation attemperater, liquid level constantly rises, until rated liquid level; This moment, magnetic valve 7 cut out, and circulation attemperater 3 left end water pumps 5 are in running order always in this process.With this, finished product hot water intermittence is carried to heat storage water tank.Large-scale heat storage water tank 4 liquid levels constantly rise, and when high liquid level warning point, system is out of service.Along with returning back to low liquid level point in the large-scale heat storage water tank 4, system roll-back, so back and forth.
The energy-conservation part of the utility model is to reclaim the heat in the thermal medium that should remove cooling system, and makes thermal medium keep stable temperature, and unit is connected with cooling system, can alleviate the cooling system thermic load.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technician of technical field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment under the present invention, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
