Description
Technical field
The present invention relates to the water heater heating for water in a kind of hot water supply system, especially relates to a kind of water heater that possesses function of recovering waste heat.
Background technology
In some hotels, hotel, usually need to arrange the hot water supply system of unified hot-water supply.In hot water supply system, be transported to each supply centre by pipeline after adopting water heater unification to tap water heating, so that management and improve efficiency of utilization.Wherein, the structure of existing water heater, comprises and the body of heater of a metal shell in body of heater, has combustion chamber, and bottom, combustion chamber has heater, and heater top has hot water pipeline, and in hot water pipeline, water can be transported to after heated and respectively use with water spot.
This existing water heater exists efficiency of utilization underground, causes the defect of energy waste.Do not meet the call of current national energy-saving and emission-reduction.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is: how to provide a kind of heat utilization efficiency better waste heat recovery water heater, can possess better energy-saving effect.
In order to solve the problems of the technologies described above, in the present invention, adopt following technical scheme:
A kind of waste heat recovery water heater, comprise body of heater, body of heater middle part has combustion chamber, bottom, combustion chamber has heater, in the combustion chamber of heater top, be furnished with hot water pipeline, it is characterized in that, in described body of heater, between chamber wall and body of heater shell, be provided with water interlayer, described water interlayer comprises the interior water interlayer and the outer water interlayer that arrange from inside to outside, interior water interlayer wraps combustion chamber, outer water interlayer wraps interior water interlayer, interior water interlayer and outer water interlayer are interconnected, on the body of heater in described outer water interlayer outside, be provided with water inlet, on the body of heater of interior water interlayer upper inner, set out the mouth of a river and hot water pipeline water inlet end joins, hot water pipeline unrolls and is communicated with the multilayer that is arranged as layer structure and is arranged as horizontal direction, the equal complications of the hot water pipeline formula formation rectangular configuration of advancing of unrolling in the hot water pipeline of every one deck, in every layer of hot water pipeline, the pipeline of the two end portions of the tortuous direction of unrolling is fixed on the body of heater of interior water interlayer inner side, the direction that the hot water pipeline complications of every adjacent two layers are unrolled is mutually vertical, in body of heater, be also provided with two exhaust gases passes of symmetrical distribution, described exhaust gases passes inlet end is positioned at end face on combustion chamber, behind the centre position on exhaust gases passes water interlayer top outside inlet end is upward through interior water interlayer arrival, extend along outer water interlayer upper level outward again, and then extend downwardly into from the middle part of outer water interlayer outside left and reach outer water interlayer bottom, final level outward extends body of heater, and the outer flue gas channel exit of described body of heater is also provided with the blower fan for negative pressure power is provided to exhaust gases passes.
In the present invention, in body of heater outside combustion chamber, be provided with two-layer water interlayer, wherein interior water interlayer wraps combustion chamber from top, the heat absorption utilization that combustion chamber can be given off, outer water interlayer wraps interior water interlayer from top, internally water interlayer plays the effect of insulation, further prevents that heat from overflowing body of heater, the bilateral symmetry of body of heater upper combustion chamber is provided with flue simultaneously, flue is positioned at water interlayer, can be effectively with water interlayer in water generation heat exchange, by the heat recovery and utilization of flue gas, when simultaneously flue smoke first through the higher interior water interlayer of excess temperature again through the lower outer water interlayer of excess temperature, being conducive to flue gas heat is absorbed by water, flue picks out body of heater extend downwardly into bottom of furnace body after stretching out from extend top after again again, utilize so limited furnace space at utmost to improve flue length, extend the time of flue and hydrothermal exchange, improve heat exchanger effectiveness.Simultaneously, in the present invention, water inlet is that first body of heater shell enters preheating in the outer water interlayer that temperature is lower, then enter in the interior water interlayer that temperature is higher after preheating again, heating in the last hot water pipeline just entering in combustion chamber, water interlayer and hot water pipeline form waterway circulating like this, along with the mobile replacement of water guarantees the effect that water interlayer absorbs fume afterheat, improve leaving water temperature simultaneously.In addition, in the present invention, hot water pipeline is set to a layer structure, in every layer hot water pipeline all back and forth complications be set to rectangle, can make every layer of heated volume of hot water pipeline, simultaneously, the direction of the hot water pipeline complications of every adjacent two layers is mutually vertical, clearance space between pipeline staggers mutually like this, is beneficial to further raising space availability ratio, at utmost improves heating effect.In addition, in hot water pipeline, the two ends of every layer of pipeline are fixed on the body of heater of interior water interlayer inner side, can improve the constant intensity of hot water pipeline, improved the intensity of interior water interlayer inwall body of heater simultaneously, therefore the structure of the part of directly being roasted by flame is all strengthened, effectively prevent that body of heater from high temperature deforming, improve body of heater intensity, extend its service life.Wherein, the outer flue gas channel exit of body of heater is also provided with the blower fan for negative pressure power is provided to exhaust gases passes, can guarantee like this unimpeded of flue gas, improves the effect of fuel in combustion chamber burning, improves fuel economy.
As optimization, in described exhaust gases passes, be to be bent into back and forth the mode of S shape structure to downward-extension to the downward extension of downward-extension from the middle part of outer water interlayer outside left.Like this, can further extend flue length, improve the heat exchange effect of flue and outer water interlayer.
In sum, water heater of the present invention has improved the assimilation effect of the heat energy that fuel combustion is distributed in all its bearings, body of heater substantially can not have surplus heat and distributes and waste, therefore possess the feature that heat utilization efficiency is very high, possesses the good result of the consumption of saving, meet national green environmental protection, the requirement of energy-saving and emission-reduction is called.Water heater of the present invention simultaneously, compact conformation, rationally distributed, when can at utmost guaranteeing heat absorption effect, reduce body of heater volume, save product cost.
