Description

A kind of steam raising plant

Technical field

The utility model relates to a kind of steam raising plant, particularly relates to a kind of steam raising plant that steam is provided to non-family expenses formula steam box.

Background technology

In catering industry, the application of commercial steam box is very extensive at present, can satisfy the needs in enterprises and institutions dining room etc.But the common problem that commercial steam box exists is steam raising plant and adopts ancient burner, high-power air blast rotation helps the work of energy formula, combustion gas mixes incorrect with air, having increased imperfect combustion gas produces and discharges through chimney, contaminated environment makes that not only consuming the many but also thermal efficiency of gas can not improve; Simultaneously, increase the gas quantity and the blow rate required for making heating power, make the noise of blower fan and the noise of rotary combustion increase, usually greater than 88dB, the airborne noise severe exacerbation environment of generation is unfavorable for kitchen operation.

The utility model content

The purpose of this utility model is exactly at the deficiencies in the prior art, and the combustion-supporting high-efficient energy-saving environment friendly of a kind of air blast, oligosaprobic steam raising plant are provided, and not only combustion gas and air mix fully, the efficiency of combustion height, burnup is low, and disposal of pollutants is low, water heating simultaneously is fast, and the blow rate required is low.

For achieving the above object, the technical solution of the utility model is as follows:

The steam raising plant that the utility model proposes comprises water tank, and water tank inside is provided with the heating tube that water is heated, and tank top is provided with steam (vapor) outlet, and the water tank peripheral hardware has combustion-supporting miniature small-power blower fan; Blower fan is connected with airduct one end, airduct is provided with the combustion gas inlet port, the airduct other end outwards is provided with mixed plate, horn mouth and spit tube successively, between the heat inlet of spit tube and heating tube certain distance is arranged, combustion gas and air fully mix the back, burn through the spit tube ejection in airduct, inject heat inlet, thereby the water in the water tank is heated, produces steam.

Described mixed plate comprises the flat orifice plate away from the convex mixed plate of spit tube and close spit tube; The convex mixed plate is 2, is evenly distributed with some apertures on it; Be provided with a macropore in the middle of the flat orifice plate.The external diameter of described convex mixed plate is 58mm, and the hole diameter on it is 4mm, and pitch of holes is 3mm; The external diameter of described flat orifice plate is 48mm, and middle big bore dia is 38mm.Described bell-mouthed diameter at butt end is 58mm, and top diameter is 25mm, highly is 20mm.Distance between described spit tube and the described heat inlet is 20mm, and certain impulse force is arranged when the flame of spit tube is injected heating tube during work, along with impulse force can be brought required little air into and replenishes, feasible burning is more abundant, reduce disposal of pollutants, the blow rate required is less and reduce noise, shortens heat time heating time.

The utility model in use, after combustion gas enters airduct from the combustion gas inlet port, carry out mixing the first time with air, by the thrust of wind gaseous mixture being pushed mixed plate carries out the second time and mixes, gaseous mixture by mixed plate enters horn mouth and mixes for the third time, through three mixed gases through spit tube ejection burning.Three abundant mixed gas combustions are abundant, and its flame all is blue, thereby make that efficiency of combustion improves, CO emission reduces, and protected environment.The flame that mixes after-combustion can not stop in the mixing position, mainly is the thrust and the small suction of chimney of gaseous mixture, and spit tube is constantly supplied with gaseous mixture in the rear end, spraying into heating tube burns, waste gas is also constantly discharged from chimney, thereby improves efficiency of combustion, has reduced burnup.

For making the steam box can faster acquisition steam, be provided with four heating tubes in the described water tank and simultaneously the water in the water tank be heated.Described airduct comprises air main and branch airduct, and blower fan is connected with air main, and air main is provided with four branch airducts, is respectively equipped with the combustion gas inlet port on it; Combustion gas and air mix the back respectively, burn through four spit tube ejections in minute airduct, inject the heat inlet of four heating tubes respectively.Article two, the centre distance between the heating tube is 100mm.Distance between combustion gas inlet port and the spit tube is for dividing 1/4th of airduct length.

Described heating tube is S-type in water tank, because the time that S type heating tube expels the heat-evil in water tank lengthening, its heat energy is fully very little by the heat that water absorbs, discharges, and only is 1/4 of common steam box.Simultaneously, in order to make full use of the heat energy of spit tube place burning, the width of water tank bottom is designed to littler than the width of water tank upper, is ladder step shape, the heat inlet of heating tube is positioned at the ladder step place of water tank bottom; The residual flame temperature of spit tube also has more than 50% and can be absorbed by a part of stainless steel casing that water tank upper grows like this, thereby realizes economizing gas more than 35%, and noise control produces the time of same steam than common steam generating means raising 1/3 at 55dB.

Compared with prior art, the beneficial effects of the utility model are: the combustion gas of commercial steam box steam raising plant and air are fully mixed for three times, adopt four-head interlock air blast, improve the efficiency of combustion and the thermal efficiency, reduce burnup and disposal of pollutants, reduce the blow rate required and reduce noise, realize economizing gas, power saving, simultaneously noise reduction, low blowdown.
