A kind of heat collector that is used for the shower waste waste heat recovery
The utility model relates to a kind of heat collector of shower waste waste heat recovery, belong to civilian electric heater energy-saving field, the heat in the waste water that produces when being intended to gather shower, the degree of depth that reaches water heater is energy-conservation.
At present, mostly electric heater power-saving technology that industry adopts is heat pump techniques, and its low-temperature heat source adopts air source, because air source heat pump has tangible power savings advantages than the traditional electrical water heater.It is a principle of having used " contrary Carnot cycle ", it with consume a part of electric energy be cost (compensation) through thermodynamic cycle, discover and use the energy of storages such as air (heat), be used for producing hot water.
As a kind of energy-efficient device, the energy-saving effect of Teat pump boiler largely depends on the quality of low-temperature heat source.That is to say that the temperature of low-temperature heat source is high more, the Teat pump boiler Energy Efficiency Ratio is high more so, and is just energy-conservation more.Otherwise then Energy Efficiency Ratio reduces, and energy-saving effect is poor.At present, household heat pump water heater is many to be main with air source heat pump, and promptly low-temperature heat source adopts air, and heat pump and air carry out heat exchange, gathers the central heat of air.Thereby produced some problems, in warm season, especially summer, because the heat that contains in the air is higher, the Energy Efficiency Ratio of heat pump is very high, and is very energy-conservation.But arrived cold winter, it is very low that the Energy Efficiency Ratio of heat pump just becomes, and because the defrost of frequent employing electric energy has no longer had energy-conservation advantage.
The core break-through point that addresses this problem is to seek the constant low-temperature heat source of Teat pump boiler, and the heat collector that can carry out the available heat exchange with this thermal source.
Summary of the invention
The purpose of the utility model is that the waste heat of waste water makes it the low-temperature heat source as heat pump when collecting shower through the heat collector of this shower waste waste heat recovery; The temperature of this part waste water very high (usually at 35 ℃--between-42 ℃), capacity is also very big, and the heat collector of this shower waste waste heat recovery (abbreviation heat collector) is made up of water leg, inlet, water leg dividing plate, heat exchanger coils, heat exchanger fin five parts; This heat collector is tiled on the ground of shower position, and area is about 0.8～1.5 square metre, and this area is enough to accept the current that gondola water faucet sprays; The height of water collector is in 30～60 millimeters scopes, and the inside of water collector is provided with the water flow grooves of a chain of water stream channel of labyrinth-like U font, to prolong the heat exchange path; Water collector also is provided with discharge outlet in order to connect floor drain, in the water flow grooves of water collector, heat exchanger is installed, and the loam cake of water collector adopts stainless (steel) wire liner reinforcement; Square is divided into the mouth of a river of infundibulate or slope shape, and purpose is to concentrate the water of gathering from this mouth of a river to flow out the heat exchanger below supplying with; The position at the mouth of a river is located at the porch in labyrinth; And the delivery port of water collector is located at the outlet in labyrinth, and during shower, the people stands on the square of water collector; Stainless (steel) wire covers can lay the rubber net; After the heat of this heat collector collection and air source heat pump carried out heat exchange, the heat that can fully absorb waste water heated the water of water heater, can improve the Energy Efficiency Ratio of heat pump greatly.
The characteristics of this utility model are:
Characteristics one: this heat accumulator be shaped as rectangle or circle, area is at 0.8～1.5 square metre, height is in 30～60 millimeters scopes.
Characteristics two: this heat collector is provided with the water flow grooves of a chain of water stream channel of labyrinth-like U font, and the inlet one of water fixes on the porch of labyrinth separate slot, and outlet one fixes on the exit of labyrinth separate slot.
Characteristics three: the square above the water collector is divided into infundibulate or slope shape inlet, and this inlet communicates with the inlet of labyrinth-like water proof groove, in the middle of the water proof groove heat exchanger is set, and the heat collector outlet directly links to each other with floor drain.

The specific embodiment
The process that accompanying drawings the utility model is realized,
The utility model is a kind of heat collector of gathering shower waste; It utilizes the low-temperature heat source of shower waste as Teat pump boiler; Heat collector constitutes a chain of water stream channel of labyrinth-like U font by the heat collector dividing plate, and heat exchanger is arranged in this passage, and the waste water residual heat of gathering is reclaimed.Adopt the mode of solid matter heat exchanger fin on copper (aluminium) coil pipe to realize good waste heat collection, coil pipe adopts circuitous the arrangement, gathers distance to prolong heat, strengthens the heat exchange effect, and heat absorbs through the refrigerant in the coil pipe, and the storage tank to water heater discharges again.Among the figure 1 for water leg, square is divided into infundibulate or slope shape inlet 2 on water leg 1, set inside has water leg dividing plate 3; Be provided with heat exchanger in the passage that dividing plate forms; Heat exchanger is made up of heat exchanger coils 4 and heat exchanger fin 5, and the waste water of shower gets into inlet 2, gathers to water leg import 6 through the water collector upper cover plate, and waste water is along a chain of channel flow of U type; Carry out discharging from water leg outlet 7 after the heat exchange with heat exchanger, flow directly into floor drain.
The utlity model has simple in structure, multiple functional, practical characteristics.
