Description

The dual-purpose furnace system of gas-heating supplying hot water
Technical field
The present invention relates to a kind of gas heating equipment, more particularly to a kind of dual-purpose furnace system of gas-heating supplying hot water.
Background technology
Traditional dual-purpose furnace system of gas-heating supplying hot water is to absorb heat caused by fuel gas buring using heat exchanger, is passed Pass and provide heating water inlet by water circulating pump, after heat exchange, the water temperature of heating water inlet raises to form heating water outlet, then heating Water outlet provides heat to heating system through heating outlet pipe or supplies bath water system thermal through plate heat exchanger.
As shown in figure 9, the existing dual-purpose furnace system of gas-heating supplying hot water includes heating return pipe, the water being arranged in casing Pump, gas burner, combustion heat exchanger, plate heat exchanger, heating outlet pipe, bath water water inlet pipe, bath water outlet pipe;Its Middle heating return pipe is connected by water pump with the water inlet end of combustion heat exchanger, and the water outlet of combustion heat exchanger passes through triple valve It is divided into two-way, is connected all the way with heating outlet pipe, another way is connected with the water inlet end of plate heat exchanger middle case, plate heat exchanger The water outlet of middle case is connected also by water pump with the water inlet end of combustion heat exchanger, bath water water inlet pipe, bath water outlet pipe Connected respectively with the water inlet end of heat exchanger tube in combustion heat exchanger and water outlet.Gas burner to combustion heat exchanger into Row heating, heating return pipe, water pump, combustion heat exchanger and heating outlet pipe form heating water heating circuit together, and heating goes out Heating equipment (such as floor heating) is equipped between water pipe and heating return pipe;Combustion heat exchanger, plate heat exchanger, water pump are formed together Bath water heating circuit, bath water water inlet flow out confession by becoming hot water after plate heat exchanger into cold water from bath water water outlet People uses.Gas burner to be heated to combustion heat exchanger, by exhaust passage arranged by the high-temperature flue gas for generation of burning Go out.
Such as the Chinese utility model patent of a Patent No. ZL200520129392.8 (notification number CN2830959Y)《One Kind Novel condensation formula heating/hot water gas two-purpose stove》, Application No. ZL201610650092.7 (Publication No. CN10615229A Chinese invention patent)《A kind of condensed type combustion gas warms up bath dual-purpose stove》, disclose such a gas two-purpose Furnace structure.
At present, burner used by gas two-purpose stove, including the housing of combustion chamber is internally provided with, it is provided with combustion chamber The fire row piece that multiple spacing side by side are set, fire row piece include a fuel gas inlet and multiple main flame-holes, which is revealed in shell The side wall of body, each main flame-hole are arranged on the top surface of the fire row piece, the above-mentioned each main flame-hole of a flow passage and combustion are additionally provided with fire row piece Gas entrance.Such as the Chinese invention patent of a Patent No. ZL201210121833.4 (notification number CN102635863B)《Burning Device and the gas and hot water equipment using the burner》Disclose such a burner structure.
In existing burner use metallic plate housing, this housing heat insulation effect is poor, thermal losses is big, it is not energy saving and Oxynitrides is high during burning, and metal shell easily conducts noise, and during burner operation, noise is big;Because housing heat insulation effect is poor, directly Connecing causes the temperature rise of closure periphery, not only results in the waste of heat, and the thermal efficiency is low, and easily causes hot water facility (such as two With stove) internal electronic component because high temperature service life is decayed or is damaged, seriously affects the service life of hot water facility;Combustion chamber periphery Condensed water is easily formed, condensed water easily accumulation is formed outside current outflow housing.
The content of the invention
The technical problems to be solved by the invention be for above-mentioned state of the art and combustion can be made full use of by providing one kind The dual-purpose furnace system of gas-heating supplying hot water of heat produced by burner, the dual-purpose furnace system effectively reduce heat loss, improve thermal effect Rate can reduce the temperature rise of burner periphery and the generation of condensed water at the same time.
The present invention solve the technical solution that uses of above-mentioned technical problem for:A kind of dual-purpose furnace system of gas-heating supplying hot water, Include heating return pipe, water pump, gas burner, combustion heat exchanger, plate heat exchanger, heating outlet pipe, bath water into Water pipe, bath water outlet pipe;Heating return pipe, water pump, combustion heat exchanger and heating outlet pipe form heating water heating together Circuit, combustion heat exchanger, plate heat exchanger, water pump form bath water heating circuit together, and bath water water inlet pipe, bath water go out Water pipe is connected with the water inlet end of heat exchanger tube in plate heat exchanger and water outlet respectively;Gas burner includes having combustion chamber in it Housing, the fire row piece of multi-disc spacing side by side setting is installed, the fuel gas inlet of fire row piece is connected with gas inlet in combustion chamber Pipe;It is characterized in that:At least the left and right and rear portion of wall is equipped with the thermal insulation layer made of heat-insulating heat-preserving material in the combustion chamber, Heat-absorbing water pipe is equipped with the position at the left and right and rear portion of neighbouring combustion chamber, the water inlet of heat-absorbing water pipe is connected with bypass water inlet Pipe, the water outlet of heat-absorbing water pipe are connected with bypass outlet pipe;The water inlet end of the bypass water inlet pipe connects with bath water water inlet pipe Logical, the water outlet of the bypass outlet pipe is connected with bath water outlet pipe.
As a kind of specific pipeline connecting mode, above-mentioned heating return pipe passes through water pump and the water inlet end of combustion heat exchanger Connection, the water outlet of combustion heat exchanger is divided into two-way by triple valve, connected all the way with heating outlet pipe, another way with it is board-like The water inlet end connection of heat exchanger middle case, the water outlet of the plate heat exchanger middle case is also by water pump and combustion heat exchanger Water inlet end connection.Heating and the mutual switching of bathing function are realized by operating triple valve, it is easy to operate.
As an improvement, being connected between above-mentioned bath water water inlet pipe and heating return pipe by filling pipe, filling pipe is equipped with Water supply valve.After long-time use, water can be reduced in pipeline in heating loop, at this moment can be by opening water supply valve to circuit Moisturizing is carried out in pipeline, after moisturizing, closes water supply valve.
It can be gone bad using water in pipeline in circuit for a long time, or need to safeguard system, this is just needed to circuit Interior water is excluded and replaced, and a drainpipe is connected to by above-mentioned heating return pipe, and drainpipe is equipped with drain valve.During draining only Drain valve need to be opened.
Further improve, in the embedding thermal insulation layer being provided at the left and right and rear positions of combustion chamber of above-mentioned heat-absorbing water pipe.
