Technical field
The utility model relates to heat recovery and utilization equipment, particularly a kind of excess heat recovery device for shower waste water.
Background technology
Existing bathing mode all is running water to be heated to about 40 ℃ of states through various water heaters use, about 35 ℃ spent hot water flows directly into drainpipe and drains in the shower process, spent hot water's temperature through the shower process is still higher, and its heat does not obtain utilizing, and slatterns in vain.In order to address this problem, application number is that 01235697.2 Chinese utility model discloses a kind of " shower waste heat recovery device " that reclaims used heat.This recycle device profile is a rectangular box, inside is provided with some midfeathers and diaphragm plate, diaphragm plate will be divided into some waste water tunnels in the casing, midfeather is reserved the space that allows waste water pass through, copper pipe is installed in the middle of midfeather, with diaphragm plate copper pipe and midfeather are fixed, the two ends of copper pipe are respectively equipped with running water connector and water heater connector, one side of casing is established waterwater entrance, and the casing opposite side is provided with discharge outlet.This recycle device can be realized the shower waste waste heat recovery, but also there is tangible shortcoming: adopt diaphragm plate with after being divided into some waste water tunnels in the casing, the flow and the flow velocity of waste water can not guarantee uniformity in each passage, the flow of waste water is big in the runner that has, flow velocity is very fast, but owing to can only contact the part heat exchanger tube that is positioned at this runner, so can only realize local heat exchange, again since flow velocity very fast (because of flow channel length shorter relatively), so heat exchanger time is shorter, heat exchange efficiency is relatively low; The flow of waste water is less in the runner that has, also lower with the heat exchanger effectiveness of heat exchanger tube, cause the waste of heat transfer space in the runner, so this waste heat is even inadequately with the heat exchange of receiving apparatus, do not reach desirable heat exchange effect, and, also cause the inconvenience of dismounting, cleaning heat exchanger tube owing to be provided with longitudinal and transverse dividing plate.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple and reasonable for structure, and heat exchange is even, the excess heat recovery device for shower waste water that heat recovery efficiency is high.
The purpose of this utility model realizes by following proposal: this excess heat recovery device for shower waste water comprises water-collecting tray, heat exchange cavity, heat-exchange tube, water-collecting tray is positioned at heat exchange cavity top, heat-exchange tube is positioned at the heat exchange cavity, it is characterized in that: be provided with supporting clapboard in the described heat exchange cavity, form circuitous waste water runner along heat-exchange tube, described supporting clapboard upper/lower terminal is connected with water-collecting tray and heat exchange cavity diapire respectively, can play a supportive role to water-collecting tray, described heat-exchange tube is fixedly mounted in the heat exchange cavity by supporting clapboard.
Described heat-exchange tube is the inclined coil pipe that circles round.Adopt this heat exchanger tube to make and obtain bigger heat exchange area and heat exchanger time in the useful space, heat exchanger effectiveness is higher.In order to improve heat exchanger effectiveness better, fin can also be set on heat-exchange tube.
The described inclined vertical or horizontal direction of coil pipe in runner of circling round is the undaform bend pipe; Described undaform bend pipe can make water produce turbulent flow in flow process, reaches the purpose of abundant heat exchange.
One end of described heat exchange cavity is provided with the water-collecting tray discharge outlet, and the other end is provided with the overflow-type discharge outlet, and described overflow-type discharge outlet is higher than the position of heat-exchange tube; Can make spent hot water's submergence heat-exchange tube all the time like this, keep heat exchange to stablize and continue, finish fully.
Described water-collecting tray discharge outlet is provided with filter element, and described filter element can be screen pack or filter, is used to prevent that the bigger object of volume from falling into heat exchange cavity internal congestion runner.
Described water-collecting tray adopts the design of movable detachable, is more convenient maintenance, water-collecting tray or water-collecting tray partial design become can the unlatching activity the heat exchange chamber cover plate; Described water-collecting tray also can be designed to different version, as the shower type water-collecting tray of bathtub, bathing pool or other shapes (circular, square, fan-shaped etc.).
But be provided with the mudhole of switch in the described heat exchange cavity, safeguard to make things convenient for periodic cleaning.Described mudhole can be located at the downside of overflow-type discharge outlet or be positioned at the cavity diapire.
The outward appearance of this excess heat recovery device for shower waste water, structure, specification can be designed to various forms, to be fit to different consumer needs.Described water-collecting tray and heat exchange chamber can adopt materials such as pottery, plastics, corrosion resistant plate, polyester sheet to make; Described heat-exchange tube can adopt corrosion-resistant, high heat conducting internal and external threads tubing such as stainless steel, copper to make.
Action principle of the present utility model is: adopt gravity flow heat exchange design, water relies on potential difference to flow naturally in heat exchange chamber, do not need external energy, and employing overflow-type drainage pattern, keep waste water to flood heat-exchange tube all the time, just discharge heat exchange chamber after heat is fully exchanged, make that heat exchange is more abundant, heat recovery rate is higher.
The utility model has advantage and effect under following with respect to prior art: (1) heat exchange is even, heat recovery rate is high; The circuitous flow passage that shower waste promptly forms along supporting clapboard after flowing in this device heat exchange chamber equably, fully contact with heat-exchange tube simultaneously and carry out reverse heat-exchange (being that the outer fluid flow direction of interior fluid of heat exchange pipe and pipe is opposite), the setting of circuitous runner increases flow channel length greatly, heat exchanger time obtains prolonging, and has avoided prior art respectively along the flow of different flow passage and the shortcoming that flow velocity is inhomogeneous, heat exchanger time is short; And owing to adopted the bigger inclined coil pipe that circles round of heat exchange area in the unit volume, and the described inclined vertical or horizontal direction of coil pipe in runner of circling round can be made turbulent flow for the undaform bend pipe, so strengthened heat transfer more effectively, make the waste heat recovery rate of shower waste higher, more energy-saving and cost-reducing.(2) simple and reasonable for structure, cleaning is convenient; Be provided with the water-collecting tray of movable dismounting in this device and reach the mudhole structure, can periodic cleaning safeguard, very convenient and practical; And owing to do not adopt diaphragm plate of the prior art, simplify the structure, so manufacturing cost is low, the dismounting maintenance is also very simple and easy, convenient.(3) applicability is good; This device can adopt different moulding (as shower cabinet, bathtub, bathing pool etc.) according to real needs, and its form is flexible and changeable, can be widely used in health shower places such as household, hotel, publilc baths, swimming pool, and range of application is wider, good market prospect.
