Abstract
Description
Technical field
The utility model relates to a kind of water heater, especially relates to a kind of condensed type combustion gas fast water heater.
Background technology
The conventional common exhaust gas temperature of gas instantaneous water heater is higher, and wherein the heat more than 10% discharges away with flue gas, the waste heat in the flue gas can't be made full use of, so the thermal efficiency is lower, and energy-saving effect is relatively poor.As application number is 00202629, the applying date is on February 21st, 2000, denomination of invention is the patent of safe and efficient gas heater, comprise the water heater housing, heat exchanger housing, the combustion chamber, heat exchanger, the water temperature adjusting knob, exhaust emission tube, it is characterized in that: be provided with the hydraulic turbine in the exhaust emission tube, endothermic tube, endothermic tube one end links to each other with heat exchanger inlets, the other end and hydraulic turbine outlet are joined, the hydraulic turbine is provided with ventilating fan, hydraulic turbine import links to each other with water inlet pipe, the exhaust emission tube overcoat has air input pipe, exhaust emission tube, air input pipe one end respectively with heat exchanger housing, the water heater housing links to each other.This patent structure complexity, the cost height does not make full use of flue gas institute heat content, causes the waste of heat energy.
Summary of the invention
The purpose of this utility model provides a kind of good energy-conserving effect in order to solve above-mentioned deficiency exactly, and thermal efficiency height is rational in infrastructure, corrosion resistant condensed type combustion gas fast water heater.
The utility model is realized above-mentioned purpose by following technical proposals:
The utility model comprises fuel gas buring part, heat exchanger, water circuit system, smoke evacuation pipeline, control system, fuel gas buring partly comprises burner, igniter, blower fan, water circuit system comprises water pipe, coil pipe, control system comprises gas ratio valve, water valve, controller, and described fuel gas buring partly is arranged on the top of water heater; Burner is invert form, Open Side Down for blower fan, promptly realizes the downward air blast of blower fan, the downward combustion system of flame.
Described heat exchanger is arranged on the burner below, is made up of three-stage heat exchanger, i.e. first order heat exchanger, second level heat exchanger and coil pipe.Described heat exchanger and coil surface also scribble the protective layer that can prevent the condensate water acidic corrosion.Described coil pipe downside also is provided with condensed water neutralisation treatment device.
The utlity model has following advantage:
1, owing to adopt overall arrangement form, air blast down combustion system and three grades of heat exchange methods, exhaust gas temperature is reduced greatly, effectively raise the thermal efficiency, can improve more than 15% by the conventional gas instantaneous water heater thermal efficiency towards following formula; Oxious component also significantly reduces in the discharging flue gas.
2, the utility model compact conformation is reasonable, and cost is low; Heat exchanger and coil surface stopping off can prevent the sour corrosion of condensed water effectively.
3, the utility model also is provided with proportioning valve, water valve, can carry out water temperature control easily.
4, the utility model also is provided with condensed water collection, neutralisation treatment bleed unit, protects environment effectively.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural principle schematic diagram of the present utility model.
Specific embodiment
As Fig. 1, the utility model comprises fuel gas buring part 1, water circuit system 2, smoke evacuation pipeline 3, control system 4, heat exchanger 6.Fuel gas buring part 1 is arranged on top of the present utility model, fuel gas buring part 1 comprises burner 1-1, igniter 1-2, blower fan 1-3, burner 1-1 is an invert form, and Open Side Down for blower fan 1-3, promptly realizes the downward air blast of blower fan 1-3, the downward combustion system of flame.
Water circuit system 2 comprises water pipe 2-2, water pipe 2-3 and coil pipe 2-1, and water pipe 2-2 is located in the first order heat exchanger 6-1, and water pipe 2-3 is located in the heat exchanger 6-2 of the second level, and coil pipe 2-1 is located at second level heat exchanger 6-2 below.
Heat exchanger 6 is arranged on burner 1-1 below, is made up of three-stage heat exchanger, i.e. first order heat exchanger 6-1, second level heat exchanger 6-2 and coil pipe 2-1.
Control system 4 comprises gas ratio valve 4-1, water valve 4-2, controller 4-3, and second level heat exchanger 6-2 and coil pipe 2-1 surface scribble the protective layer that can prevent the condensate water acidic corrosion.Coil pipe 2-1 downside is provided with condensed water collector groove and condensed water neutralisation treatment device 5.
Combustion gas enters proportioning valve 4-1, this proportioning valve has functions such as ratio adjusting, voltage stabilizing, enter the air mixing after-combustion that burner 1-1 and blower fan 1-3 produce then, flame burns downwards, the high-temperature flue gas that produces enters first order heat exchanger 6-1, carry out the heat exchange first time with water pipe 2-2, this moment, flue-gas temperature reached 200 ℃.Enter second level heat exchanger 6-2 again, carry out the heat exchange second time with water pipe 2-3, this moment, flue-gas temperature reached 40-60 ℃.Waste heat is through the further heat exchange of coil pipe 2-1, and the smoke evacuation pipeline is arranged on the inside portion of water heater, and the smoke evacuation BOP is communicated with the heat exchanger inner chamber, and the outlet of smoke evacuation pipeline is arranged on water heater top; Final low temperature flue gas is discharged into outdoor by smoke pipe.
Water circuit system is discharged through heating behind coil pipe 2-1, second level heat exchanger 6-2, the first order heat exchanger 6-1 after being regulated by water valve 4-2.
Condensed water produces at second level heat exchanger 6-2 and coil pipe 2-1 place, through being collected into neutralisation treatment device 5, is discharged into sewer after the neutralization.
Controller 4-3 contrasts the back by the air quantity of control blower fan 1-3 and the tolerance of proportioning valve 4-1 to the temperature of Inlet and outlet water with temperature is set, and adjusts the combusting firepower size, carries out the control of water temperature.
As from the foregoing, the utlity model has good energy-conserving effect, thermal efficiency height, rational in infrastructure, corrosion resistant characteristics.
