Description

Liquefied petroleum gas far infrared water warming stove

The utility model includes the water heater of electro-heat equipment.

Warming, mainly contain residential quarters and office space that following several mode is concentrated resident family, the overwhelming majority adopts central heating system, but for sparsely populated resident family, owing to can not adopt central heating, thereby the mode of heating is varied, the coal stove that the employing tradition that has falls behind burns coal, both wastes energy, and discharges flue dust again, contaminated air, also make the indoor dust that has, very unhygienic, the employing electric heater that has, though not contaminated air, indoor clean hygiene have that heating area is little, power consumption is high, investment is big, the deficiency of weak effect.

The purpose of this utility model provides the good again liquefied petroleum gas far infrared water warming stove of a kind of neither contaminated air, heating effect.

This liquefied petroleum gas far infrared water warming stove comprises electro-heat equipment and heat exchanger, its design feature is that electro-heat equipment is a burner, it is suspended on the below of heat exchanger, gap between burner and the heat exchanger is the combustion zone, burner comprises shell, the inner chamber of shell is for mixing the gas storehouse, on shell, be equipped with and be funnel shaped induction tunnel, the barrel portion of induction tunnel stretches into and mixes the gas storehouse, the shell upper end is embedded with the porous far infrared ceramic plate, heat exchanger comprises housing, lower part of frame is equipped with backwater takes over, the inner chamber of housing is a water cavity, is evenly equipped with honeycomb duct in water cavity, and the lower end of honeycomb duct is communicated with the combustion zone, the upper end is communicated with exhaust air chamber, exhaust air chamber is communicated with waste heat box by exhaust steam passage, waste gas is housed on the waste heat box end face pipe, the header tank that inner chamber is communicated with the inner chamber of housing is housed on the end face of exhaust air chamber, hot water out pipe is housed on the header tank.

Improvement as to liquefied petroleum gas far infrared water warming stove also comprises the afterheat water-heating box that contacts with waste heat box with exhaust steam passage, and afterheat water-heating box is provided with water filling port and outlet valve, in the inner chamber of induction tunnel middle section position trunnion is housed.

Above-mentioned liquefied petroleum gas far infrared water warming stove, in use, the port of export with the liquefied petroleum tracheae puts in induction tunnel earlier, open the liquefied petroleum air cock, oil gas just sprays at a high speed and mixes in the gas storehouse, and form a negative pressuren zone in bell mouth place of induction tunnel, the air that contains oxygen on every side also enters through induction tunnel thereupon and mixes the gas storehouse, fully mix with oil gas, the hole of mixed gaseous mixture on the porous far infrared ceramic plate enters the combustion zone, light gaseous mixture with the burning things which may cause a fire disaster of automatic ignition device, lighter or match one class this moment, burns.The heat energy that burning is produced, the one, the housing by exchanging air passes to the water in the water cavity, the 2nd, the porous far infrared ceramic plate is along with the rising of temperature gives off a large amount of infrared rays, water in the water cavity has strong absorption to infrared ray, water temperature is raise rapidly, the 3rd, the high-temp waste gas by entering honeycomb duct is given water in the water cavity thermal energy transfer through the honeycomb tube wall.According to hot ascension principle, heated water concentrates in the header tank, and sends through hot water out pipe, after the radiator heat exchange in being placed in the room, is sent in the water cavity by the backwater adapter again, forms cyclic process.After high-temp waste gas carries out heat exchange first through honeycomb duct, temperature decreases, in exhaust air chamber, carry out the heat exchange second time again by the hot water in locular wall and the header tank, discharge partial heat energy again, carry out heat exchange for the third time by the water in exhaust steam passage and waste heat box and the afterheat water-heating box at last, go out pipe from waste gas at last and discharge.

As further improvement to liquefied petroleum gas far infrared water warming stove, on hot water out pipe, be connected to the temperature control air throttle, the temperature control air throttle comprises and is contained in the intraluminal temperature sensor of hot water out pipe, temperature sensor comprises a piston shell, the swelling agent that is compressed by piston is housed in the inner chamber of piston shell, be fixed with the outwardly directed piston rod of the tube wall that passes piston shell and hot water out pipe on the piston, outer end at piston rod is socketed with the valve base plate successively, seal membrane, return spring seat and switch valve block, wherein return spring seat and switch valve block are arranged in valve shell cavity, valve casing is fixedlyed connected with the valve base plate and is sealed by seal membrane, between the inner top surface of valve casing and return spring seat, return spring is housed, on valve casing, also be fixed with the gas inlet pipe and the combustion gas escape pipe that put in valve shell cavity, gas inlet pipe is positioned at a section of valve shell cavity and is provided with little air vent, the end of combustion gas escape pipe puts in the induction tunnel, and is serially connected with switch on its pipeline.

When just beginning, the temperature control air throttle is opened, oil gas from the combustion gas escape pipe through induction tunnel, mix the gas storehouse, burn behind the hole of porous far infrared ceramic plate, heat exchange begins, along with the water temperature in the hot water out pipe raises gradually, swelling agent in the temperature sensor expands gradually, the also synchronous drive switch valve block of piston rod is gradually near the end of gas inlet pipe, when the water temperature in the hot water out pipe reaches design temperature, the switch valve block is just shut the end of gas inlet pipe, cuts off main air feed gas circuit, after this, have only the combustion gas of trace to spray, so that it is not flame-out to keep burner from little air vent.After the water temperature in the hot water out pipe dropped to below the temperature of setting, swelling agent shrank, and drove the reverse displacement of switch valve block at the effect lower piston rod of return spring, broke away from the end of gas inlet pipe, normally supplied combustion gas again, and burner recovers normal combustion again.Above-mentioned process is gone round and begun again, and makes heating continue to carry out.

From the above mentioned, this water warming stove is owing to adopted the far infrared burner, combustion gas fully mixes with oxygen containing air again in mixed gas storehouse, guaranteed the abundant burning of burner, also carry out heat exchange simultaneously in many ways, waste heat to waste gas makes full use of again, thereby thermal efficiency height, and heating effect is good.Because the waste gas of discharging does not have flue dust, thereby contaminated air not, indoor also free from dust helps the health of health.
