Description
Technical field
The utility model relates to the gas heater technical field, is specifically related to a kind of forced-air blast fast gas heater three orifice plates and divides wind apparatus.
Background technology
In general, water heater roughly is divided into several major types such as gas heater, electric heater and solar water heater at present, and gas heater is because the efficient height, firing rate is fast, adjustment is stable, bigger heating demand can be provided, can many people use and being favored continuously.Yet there is the combustion gas poisoning that causes because of improper use in the gas heater of self arrangement, and for avoiding this potential safety hazard, the forced-air blast fast gas heater becomes chooses more gas heater in the market.
Forced-air blast fast gas heater blower fan discharge area generally is about about 2000 square millimeters, and the area of air feed is about 15800～30000 square millimeters, even bigger.And that blower fan exports to the distance of air feed face is limited, this just makes and evenly divides wind to acquire a certain degree of difficulty, because the structural limitations of present traditional forced-air blast fast gas heater, so can not make each burner can both obtain enough air, can't guarantee combustion gas completing combustion, the combustion conditions that more can't ensure each burner keeps basically identical, greatly reduced the thermal efficiency of gas heater, also caused often simultaneously because gas heater is piled up the resonance that causes because of exhaust gas volumn is excessive and uttered long and high-pitched sounds in the combustion chamber.
The utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, a kind of novelty simple in structure to be provided, and forced-air blast fast gas heater three orifice plates with low cost, that reliability is high divide wind apparatus.
The technical problem that the utility model proposed is to solve like this: a kind of forced-air blast fast gas heater three orifice plates divide wind apparatus, described three orifice plates divide wind apparatus mainly to constitute three layers of branch wind AND DEWATERING FOR ORIFICE STRUCTURE by being installed on first fen wind orifice plate in the gas heater combustion chamber, second fen wind orifice plate and the 3rd fen wind orifice plate, wherein said first minute wind orifice plate is installed on the air inlet place on the combustion chamber soleplate of gas heater, and the lower end of air inlet is connected with the fan outlet of gas heater; Described the 3rd minute wind orifice plate double as burner fixed mount is connected with burner; Described second minute wind orifice plate is installed between first fen wind orifice plate and the 3rd fen wind orifice plate.
Described first minute wind orifice plate is provided with downward kink along the two ends of combustion chamber minor axis direction (being the combustion chamber fore-and-aft direction), and the template that this kink constitutes first fen wind orifice plate is " recessed " shape structure of handstand, and described kink is welded on the combustion chamber soleplate; First fen wind orifice plate offers air that blower fan the is sent into main wind passage that divides to the shunting of both sides, combustion chamber along the two ends of combustion chamber long axis direction (being the combustion chamber left and right directions), wind orifice plate upper surface offered several equally distributed balancing orifices in first minute, and the air that blower fan is sent into is shunted by first fen these equally distributed balancing orifice of wind orifice plate upper surface.
Offer the hole of leaking informaton with the corresponding position of fresh air inlet of burner (being the combustion gas place of spraying into) on the described second minute wind orifice plate, also offered several equally distributed balancing orifices that just is distributed into air through first fen wind orifice plate in described second minute on the wind orifice plate.
Offer on described the 3rd minute wind orifice plate and the corresponding fresh air inlet sleeve joint hole of fresh air inlet of burner, a fresh air inlet of burner (being the combustion gas place of spraying into) is set in this fresh air inlet sleeve joint hole; Corresponding burner secondary air access site offers the secondary intake opening of regulating wind of burner and secondary wind air feed proportionate relationship on described the 3rd minute wind orifice plate.
Distance between the air inlet on described first minute wind orifice plate and the combustion chamber soleplate is 4mm～7mm.
Distance between the air inlet on described second minute wind orifice plate and the combustion chamber soleplate is 10mm～15mm.
The aperture of the balancing orifice on described first minute wind orifice plate and the second fen wind orifice plate is 1mm～2.5mm, and the density in hole is every square centimeter of 5～20 holes.
The aperture of the secondary intake opening on described the 3rd minute wind orifice plate is 2.5mm～4mm, and the density relationship in hole is that excess air coefficient was controlled at 1: 1.5～1: 1.7.
Operation principle of the present utility model is:
1, divide for the first time wind: first fen wind orifice plate is arranged at the air inlet place on the combustion chamber soleplate of gas heater, it is the fan outlet top, on first fen wind orifice plate, forward and backward three directions cover blower fan outlet, in these three directions, wind can only pass through from the balancing orifice of orifice plate, and a large amount of wind divides at first fen wind orifice plate both sides main under the guide effect of wind passage, is extended to the whole air feed zone of the right and left, divides at the beginning of finishing first time of wind.
2, divide for the second time wind: the wind orifice plate was arranged at first fen wind orifice plate top in second minute, whole air feed face shield is lived, wind can only pass through from the balancing orifice on second fen wind orifice plate, because it is suitable that the orifice plate wind resistance is adjusted, after making wind pass through second fen wind orifice plate, everywhere blast keeps basically identical on the whole air feed face, at second fen wind orifice plate over against a wind air inlet of burner place (being that combustion gas sprays into the place), offer bigger, the leak informaton hole identical with burner quantity, make a large amount of air can be from directly arriving fresh air inlet here one time, guaranteed that each burner can both obtain abundant air, to guarantee that combustion conditions is good, make the complete machine carbon monoxide remain on a lower level, the pass in the hole of leaking informaton, size can be done corresponding adjustment according to different types.
3, divide wind for the third time: the 3rd fen double part doing the burner fixed mount of wind orifice plate.A fresh air inlet, i.e. the combustion gas entrance of burner; Secondary intake opening, the neutral place between adjacent two burners, the density of secondary intake opening is different different because of complete machine structure.The effect of this orifice plate is the proportionate relationship that changes, regulates fresh air inlet of burner and secondary intake opening air feed by the number (being the area in hole) that changes secondary intake opening, carbon monoxide content in the flue gas is controlled at below the 200ppm, between oxygen content is controlled at 7%～8% (excess air coefficient is controlled between 1: 1.5～1: 1.7).This changes when guaranteeing that effectively each burner can obtain enough and even oxygen, and the exhaust gas volumn in having controlled effectively guarantees that the complete machine carbon monoxide reaches a desirable level, and the flue gas overall control under minimum state.Thereby reach the thermal efficiency that improves complete machine to greatest extent, and stopped in the combustion chamber, to pile up the resonance cause effectively, utter long and high-pitched sounds because of exhaust gas volumn is excessive.
In sum, the utility model divides the wind structure to solve the forced-air blast fast gas heater effectively because the complete machine poor performance of dividing the wind difficulty to cause by three orifice plates, produce the uniformity defect of bad in batches, solve the resonance of gas heater simultaneously and uttered long and high-pitched sounds, improved the thermal efficiency of gas heater effectively.
