Abstract
A full premix and catalytic side fired condensing type gas heater comprises a controller, a gas control system, a fan, a main heat exchanger assembly, a fume extractor, housing and a water control system. The main technical characteristics are that the gas heater also comprises a mixer communicating to the gas control system, a catalytic burner of catalytic side fired combustor, and a condensing heat exchanger. The mixer and the catalytic burner are communicated to the fan. The utility model has the advantages of effective reduction on the production of the harmful pollutants such as nitric oxides and carbon monoxide from the gas heater, further improvement of the thermal efficiency, easy achievement of the top exhaust mode, no drop of the condensed water on the main heat exchanger and simple structure.
Description
Technical field: the utility model relates to a kind of gas heater, and particularly a kind of full premix catalysis side is burnt condensed type combustion gas water heater.
Background technology: existing gas heater mainly comprises three component parts: combustion system, heating system and control system.Its course of work is the cold water that enters water heater, flow through behind the water control valve, enter heat exchanger, the ignition controller igniting, gas-flow enters burner through pneumatic control system, combustion gas is lighted by pulsed discharge, form stable flame, combustion gas is completing combustion in the combustion chamber, produces high-temperature flue gas, when high-temperature flue gas is flowed through heat exchanger, cold water is heated to be required health hot water.The used burner of domestic gas-fired water heater can be divided into three kinds by combustion system: diffusion flame burner, atmospheric burner, fully-premixed burner.Be divided into the formula of falling the burning, side burning formula, horizontal etc. by burning direction.When adopting the horizontal burner, when increasing condensing heat exchanger, exist the shortcoming that condensed water leaks easily if want to improve the thermal efficiency; Adopt when burning formula, when thinking flue gas when discharge at the top, more difficult on the structure; And the noxious pollutant NOx of diffusion type, atmospheric burning type, its generation, CO etc. are higher, contaminated environment; The noxious pollutant CO of fully-premixed its generation of burning is also higher.For overcoming these defectives, full premix catalysis side is burnt condensed type combustion gas water heater develop.
Summary of the invention: technical problem to be solved in the utility model provides a kind of full premix catalysis side and burns condensed type combustion gas water heater, it can reduce gas heater noxious pollutant NOx effectively, the generation of CO, further improved the thermal efficiency, flue gas is realized the top fume exhausting type easily, condensed water can not drip on the main heat exchanger, and simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is that it comprises controller, pneumatic control system, blower fan, main heat exchanger assembly, fume extractor, shell, water control system, blender, catalytic burner, condensing heat exchanger, described blender is connected with pneumatic control system, described catalytic burner is the side burner, and described blender, catalytic burner are connected with blower fan.
Main heat exchanger assembly, condensing heat exchanger, water control system are to be connected by the water route.
Controller electrically connects by circuit and pneumatic control system, water control system, blower fan, is used to control water heater working.
Pneumatic control system is connected with blender by gas circuit.
Described pneumatic control system is provided with air inlet.
Described water control system is provided with water inlet tap.
Described main heat exchanger assembly is provided with faucet.
The utility model is compared the beneficial effect that is produced with prior art:
1, because the utility model adopts combustion gas to burn through catalytic burner, reduces the NOx and the CO of noxious pollutant in the flue gas, realized environmental protection; Adopt flue gas after the main heat exchanger heat exchange,, further improved the thermal efficiency, realized energy-conservation through the condensing heat exchanger condensation; The mode that adopts side to burn, flue gas is realized the top fume exhausting type easily, condensed water can not drip on the main heat exchanger, and simple in structure.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: referring to accompanying drawing 1, the utility model comprises fume extractor 8, main heat exchanger assembly 7, catalytic burner 5, combustion chamber 6, condensed water discharge outlet 13, condensing heat exchanger 9, pneumatic control system 2, blender 4, faucet 14, water inlet tap 12, controller 1, water control system 11, blower fan 3, water route 17, circuit 18, gas circuit 16, air inlet 15 and shell 10.Wherein main heat exchanger assembly 7, condensing heat exchanger 9, faucet 14, water inlet tap 12, water control system 11, be connected by water route 17.Controller 1 links to each other with pneumatic control system 2, water control system 11, blower fan 3 by circuit 18, is used to control water heater working.Pneumatic control system 2, blender 4, air inlet 15 are connected by gas circuit 16; Blower fan 3, blender 4, catalytic burner 5, combustion chamber 6 are connected.Its course of work is: start water heater, open the health taps, water flows through water control system 11 by water inlet tap 12, and water control system 11 sends signal and gives controller 1, and water flows into main heat exchanger assembly 7, condensing heat exchanger 9; After controller 1 is received the signal of water control system 11, controller 1 control blower fan 3 rotates, controller 1 sends the electric pulse igniting, after open pneumatic control system 2, combustion gas enters blender 4 and air through pneumatic control system 2 and mixes the back and lighted by electric pulse at catalytic burner 5, the high-temperature flue gas that produces after combustion gas is fully burnt is discharged from fume extractor 8 after main heat exchanger 7 and condensing heat exchanger 9 coolings, simultaneously, current are heated behind condensing heat exchanger 9, main heat exchanger assembly 7, flow out through faucet 14; Condensed water is discharged through stream condensed water discharge outlet 13.
