Description

A kind of degree of depth reclaims the system of bath sewage used heat
Technical field
The invention belongs to energy technology field, relate to a kind of system that reclaims the Small Washing outdoor bathing place institute bath sewage used heat such as family expenses, hotel guest room, be specifically related to a kind of system of utilizing heat exchanger and the heat pump twin-stage degree of depth to reclaim bath sewage used heat.
Background technology
The bath hot water of pot-type boiler is 40 ℃ of left and right, after spray human body, temperature is still very high, greatly about 35 ℃ of-37 ℃ of left and right, current situation is that the hot water that these temperature are higher all directly drains into sewer, cause on the one hand the significant wastage of the energy, on the other hand along with the further rise of electric & gas price, resident's bath water power consumption or consumption gas expenditure further increase, therefore more and more nervous at the current energy, in the more and more higher situation of Civil Energy Consumption cost, if can effectively this part heat recovery be recycled, no matter be to saving the energy, save the electricity charge, or environmental protection has very large meaning.
At present, more existing patent and products that utilize heat pump to utilize bath sewage Waste Heat Recovery, utilize heat pump principle, using the bath sewage of discharging as low temperature cold source, and the heat extracting wherein heats running water, realizes the recovery of heat in bath sewage.But these disclosed methods more or less exist variety of issue, and the Small Washing outdoor bathing place institutes such as inapplicable family expenses or hotel guest room specifically comprise:
(1) adopt simple heat exchanger heat exchange, the carrying out of simple low degree some recuperation of heat utilizations, the profound level that cannot realize heat reclaims, still have a large amount of tow taste heats along with sewage is drained, as the Chinese patent " energy-and water-saving shower base (People's Republic of China (PRC), the patent No.: ZL200520078458.5) ", " bathroom special-purpose water heater (the People's Republic of China (PRC), the patent No.: ZL200610104570.0) ", " a kind of heat energy exchange recovery device (People's Republic of China (PRC) for bath wastewater, application number: 201010162747.9) ", " waste water heat recovering equipment and the water heater (People's Republic of China (PRC) thereof, application number: 201020672452.1) ", " shower house (the People's Republic of China (PRC) of bath wastewater heat recovery, application number: 201120034601.6) ".
(2) directly adopt heat pump to extract the single-stage recuperation of heat mode of heat, and not first and low-grade running water heat exchange, organic efficiency is significantly reduced, recovery cost increases, as the Chinese patent " bathing wastewater residue heat recycling device (People's Republic of China (PRC), application number: 200610044652.0) ", " reclaim the carbon dioxide heat pump water heater (People's Republic of China (PRC) of water for bathing waste heat, application number: 201010564629.0) " " the waste heat back-heating type immediate heating type Teat pump boiler (People's Republic of China (PRC), application number: 200920141101.5) ", " with the air source hot pump water heater (People's Republic of China (PRC) of waste heat recovery plant, the patent No.: ZL200620024573.9) ".
(3) system or set up a plurality of water tanks separately, cannot miniaturization, maybe needs to build waste water of bath collecting pit, installs more loaded down with trivial detailsly, is not suitable for area little and fitted up the bathroom of sizing, can not be applied to the individual bathing places such as family expenses and hotel guest room.Application scenario is different, also completely different to the requirement of technological invention, the recovery that more existing patents can only be applied large-scale bathing occasion bath sewage used heat at present, as bathhouse, natatorium etc., large-scale bathhouse and family expenses, as Chinese patent " a kind of bath wastewater two levels of thermal retracting device (People's Republic of China (PRC), application number: 201210366509.9) ", " a kind of wash apparatus of heat pump of recovering residual heat from bathhouse (the People's Republic of China (PRC), patent No. ZL200610112860.X) ", " a kind of two-stage waste-water heat-energy recovery device, application number: 201020645625.0 ".
There is very large difference bathing feature and the application scenario of hotel guest room, comprising:
1) Takd A Bath The Space that close at the Small Washing such as family expenses and hotel guest room outdoor bathing place is limited, and the degree of depth that realizes bath sewage used heat in limited space reclaims, and the structure of system and flow process are had relatively high expectations;
2) bathing that close at the Small Washing such as family expenses and hotel guest room outdoor bathing place disperses, bathing time randomness is stronger, bath sewage amount is less, bathing gap periods is longer, the bathing time, the spatial concentration that are different from large-scale bathhouse, bath sewage amount is larger, and bathing gap periods is shorter, the discharge of bath sewage used heat is collected convenient, reclaims and utilizes easily.The residual neat recovering system that family expenses or hotel guest room are used requires to arrange simple, and it is convenient to reclaim, and is easy to control.
The another way of the heat pump residual neat recovering system that solution family expenses or hotel guest room are used is the system that adopts immediate heating type, has save large water tank, is conducive to install in the family expenses confined space.As Chinese patent " instant heating type heat pump energy-saving water heater (People's Republic of China (PRC); the patent No.: ZL200620053000.9) ", but its greatest problem is to be not activated thermal source, this can bring two more serious problems: 1) at the bathing initial stage, can only from running water, extract heat, wasting a large amount of running water, is another kind of waste in the more and more nervous city of water resource; 2) discharge due to bath wastewater always lags behind bathing, and the occasion in individual bathings such as family expenses or hotels, in bathing process, personnel open hot water valve and close time of hot water valve shorter, and this immediate heating type unit operation is controlled difficulty, and whole unit cannot move even.Likely unit just starts, because closing hot water valve, bathing personnel have to again stop at once, when bathing personnel open valve again, hysteresis due to bath wastewater discharge, the unit startup that must lag behind, what now likely flow out in hot water tap is cold water and cannot bathing, the hysteresis of this system self is contradictory when being heat request, last result is not unit frequent start-stop or does not simply start (losing recuperation of heat meaning), be exactly in bathing process, bathing personnel keep hot water valve often to open always, take and sacrifice water resource and the energy and guarantee that system can stable operation as cost.
Chinese patent " shower hot gas afterheat of hot water recovery type Teat pump boiler (People's Republic of China (PRC); application number: 201320102848.6) " has all been announced a kind of heat pump principle method of heat-obtaining from bath wastewater and air respectively of utilizing with " waste-heat recovery double-source heat pump water heating system (People's Republic of China (PRC); application number: 201110239271.9) ", but it is little and fitted up the bathroom of sizing that the method is not suitable for area equally, is also not suitable for family expenses and hotel guest room individual's bathing place.It is the reasons are as follows: first these methods all do not arrange and independently start thermal source, thereby make can only from running water or room air, extract heat at the bathing initial stage.As previously mentioned, from running water, extract the running water that heat means that waste is a large amount of, also the difficulty that exists operation to control, from room air, extracting heat starts required heat and does not possess operability in order to meet system, because be difficult to extract enough startup heats, make hot water meet bathing requirement, and can make that air themperature is more and more lower cannot meet the required environment temperature of bathing; Next is different from large-scale bathhouse, in order to guarantee the air quality in bathroom, need to discharge certain air, thereby can fully reclaim this part airborne heat, and the individual bathing place of family expenses or hotel guest room, the bathing time is short, and the air themperature in bathing process when guaranteeing bathing is unlikely to too low, can not discharged air; The space in the individual bathing place of last family expenses or hotel guest room is limited, allows to realize above-mentioned conception, and its whole system is installed and also had larger difficulty.
In addition, " a kind of bath wastewater two levels of thermal retracting device (People's Republic of China (PRC), the patent No.: ZL201210366509.9) " a kind of two levels of thermal retracting device reclaiming by heat exchange and heat pump disclosed, but the subject matter that this device exists is independently not start thermal source equally, exist equally above-mentioned at the bathing initial stage, can only from running water, extract heat, waste the problem of a large amount of running water, and this matching requirements sets up water leg, evaporimeter, heat exchanger, condenser, heat-collecting box, whole device is huge, install more loaded down with trivial details, be not suitable for area little and fitted up the bathroom of sizing, be not suitable for family expenses and hotel guest room individual's bathing place.
In sum, the recuperation of heat mode of current published bath wastewater or because yield is little, can not the degree of depth reclaim; Or because organic efficiency is low, reclaim cost large; Or due to without independent startup thermal source, waste valuable water resource; Or System Construction is complicated, cannot miniaturization, do not meet the restriction of installing space, all can not be applicable to the individual bathing place of family expenses or hotel guest room.Two key issues for the required solution of individual bathing Waste Heat Recovery of family expenses or hotel guest room: the one, efficient, the 2nd, requisite space is little, installs simply, proposes patent of the present invention.
