Abstract
The invention discloses a smoke-recyclable gas instantaneous water heater. The smoke-recyclable gas instantaneous water heater comprises a gas instantaneous water heater body. The gas instantaneous water heater body comprises a combustor, a smoke heat exchanger, a smoke outlet channel, a water inlet pipeline, a water outlet pipeline and a combustion chamber air inlet channel. An air blower is arranged on the air inlet channel. The smoke-recyclable gas instantaneous water heater is characterized in that a smoke backflow pipeline is additionally arranged in the smoke outlet channel in the gas instantaneous water heater, one end of the smoke backflow pipeline is connected with the smoke outlet channel, and the other end of the smoke backflow pipeline is connected to an air inlet of the air inlet channel. By the adoption of the smoke-recyclable gas instantaneous water heater, burnt smoke can be reused, the work efficiency of the whole machine is improved, the combustion temperature is lowered by the adoption of backflow of smoke, and emission of nitrogen oxide is reduced.
Description
Technical field
The present invention relates to gas instantaneous water heater technical field, more particularly, to the gas instantaneous water heater skill of environmental protection and energy saving
Art field.
Background technology
The gas instantaneous water heater of prior art is only limitted to arrange condensing heat-exchange on exhaust gases passes for the utilization of flue gas
Device, then flue gas discharged again, so its CO, NOXThere is the problem of environmental pollution such as excessive in discharge, therefore for existing combustion gas
Fast water heater flue gas is all directly to be discharged by smoke pipe after heat collecting sheet heat exchange and condensing heat exchanger (freezing machine) heat exchange, and
Do not recycle, make flue gas take away partial heat, also affect overall efficiency.
The content of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art and provides a kind of flue gas to after burning and recycle,
The work efficiency and the backflow reduction ignition temperature using flue gas of whole machine are improved, a kind of flue gas of the discharge of nitrogen oxides is reduced
Gas instantaneous water heater capable of circulation.
In order to reach object above, patent of the present invention is adopted the following technical scheme that：
A kind of flue gas gas instantaneous water heater capable of circulation, including gas instantaneous water heater main body, gas instantaneous water heater
Main body includes burner, flue gas heat exchanger, and exhanst gas outlet passage, inlet pipeline and outlet pipeline, combustion air air intake are logical
Road, is provided with aerator on air intake passage, it is characterised in that described to set up in the exhanst gas outlet passage of gas instantaneous water heater
Smoke backflow pipeline, smoke backflow pipeline one end connection exhanst gas outlet passage, the other end is connected to the air intake of air air intake passage
Mouthful.
Further illustrating as such scheme, the end in smoke backflow pipeline arranges band with the secondary wind place of mixing
The flue gas dividing plate of exhaust smoke hole, lower section of the flue gas dividing plate in fan outlet, using the Involving velocity of fan outlet injection flue gas is made
Backflow.
Further, the flue gas dividing plate exhaust smoke hole from left to right by it is close to dredge, to ensure that flue gas is uniformly discharged.
Further, regulating valve is set, the regulation and control of regulating valve can be by mainboard control, regulating valve on the smoke backflow pipeline
The percentage ratio that backflow flue gas account for total flue gas is adjusted by controlling the aperture of smoke backflow.
Compared with prior art, a kind of test system that patent of the present invention is provided has the advantages that：
The present invention by arranging smoke backflow pipeline, adopt flue gas recirculation can improve the burn-off rate of whole machine fuel with
Improve whole machine work efficiency (particularly big load or liquefied gas type) and by the cycle down low combustion temperature of flue gas to drop
The discharge of low NOx.Controlled with the company of main frame by the setting of flue gas dividing plate and the layout of exhaust smoke hole and control valve, can be made
Adjust flue gas and enter the uniformity and inlet, make flue gas and using more abundant.
