The utility model is reasonable in structure, simple and easy handle in construction, thus solving the big problem that how to make the waste paddy shells valuable without environmental pollution; moreover, the utility model is in particular suitable to paddy processing mills and areas neighboring the paddy processing mills.
Description
Affiliated technical field
The utility model relates to boiler, and particularly the boiler of combusting rice hull belongs to the boiler technology field.
Background technology
Hundred million jin of China's annual paddy output hundreds ofs, nearly 10,000,000,000 jin of the rice husk that the processing back produces, rice husk proportion is little, and volume is big, and rice husk is piled up almost similar with the paddy stacking volume, and especially in some paddy processing factories, pile up like a mountain for its rice husk.And rice husk is inflammable and spontaneous combustion, very easy breaking out of fire; The rice husk volume is big, and proportion is little, very easily drifts everywhere with the wind, influences environmental sanitation; Even stack, its occupied ground is bigger, not only influences environmental sanitation if throw away to transportation at a distance, and waste of manpower, material resources, so, rice husk is turned waste into wealth, promptly energy savings is removed a hidden danger again, especially paddy processing factory has been become a difficult problem anxious to be solved.This also is an outlet handling rice husk to make fuel with rice husk on Industrial Boiler, but because the rice husk calorific value is little, easily catch fire, be difficult for burning, and smoke contamination is serious, and the existing structure of Industrial Boiler is limit, generally combusting rice hull is undesirable on Industrial Boiler, easy burn-out material gate catches fire hopper, and smoke contamination is serious.
Summary of the invention
The purpose of this utility model is: a kind of boiler of combusting rice hull is provided, neither burns out the material gate, hopper can not catch fire yet, and smoke contamination is also controlled.
The technical scheme that the utility model adopted is: it is improved on the basis of existing horizontal chained fire grate packaged boiler, and it includes boiler body, smoke pipe, deduster, tower water spray deduster, air-introduced machine, water tank type smoke abatement device and chimney etc.Boiler body adopts the type of furnace of packaged boiler, and it is made up of material flashboard, hopper, face arch, economizer, flue, drum, fall pulp water pond, rear arch, traveling-grate stoker and partition wall etc.It is characterized in that the face arch of boiler body and partition wall improve a segment distance than the face arch and the partition wall of packaged boiler, reach 10~30cm.The purpose of raising face arch is the firebreak of correspondingly having thickeied behind the material gate, has reduced and has given combustion district temperature, prevents to catch fire in advance; The purpose of raising partition wall is in order to stop rice husk dust a large amount of in the combustion gas, it to be dropped on the traveling-grate stoker burn away, to improve the thermal efficiency.The material flashboard of boiler body front portion, the centre is provided with a water cavity, and passes to cooling water, in order to reduce the temperature of material flashboard, prevents to burn out material flashboard and hopper and catches fire; Be all-sealed structure between around clan's slag place and the following clan pulp water pond behind the boiler body, guaranteeing the sealing of body of heater, the minimizing heat-energy losses, the raising thermal efficiency is convenient to the air inducing of air-introduced machine; Because rice husk proportion is little, contains more flue dust in the combustion gas, so the deduster of on dust suppression, on adopting former boiler, using, a tower water spray deduster is set between deduster and air-introduced machine; Between air-introduced machine and chimney, be provided with water tank type smoke abatement device.
The air inlet pipe of tower water spray deduster connects deduster, and escape pipe connects air-introduced machine, tower body Lower Half dress water, and air inlet pipe extends water surface site downwards, and the tower body internal upper part is equipped with water spray system.
The air inlet pipe of water tank type smoke abatement device connects air-introduced machine, escape pipe connects chimney, water is equipped with in bottom in it, some upper and lower dividing plates are equipped with on top, the left side is by the upper spacer I at air inlet pipe place, the installation site is downwards near the water surface from the top, the lower clapboard II on upper spacer I the right, the installation site is upwards to install from water, one space is arranged between its top and the top board, and the upper spacer III on lower clapboard II the right is the same with upper spacer I installation site, and the lower clapboard IV and the lower clapboard II on upper spacer III the right install equally, analogize therewith, 1~n upper spacer and lower clapboard can be installed in the water tank.
The course of work of the present utility model is such: when rice husk drops into traveling-grate stoker by hopper, after the quantity by material flashboard control charging, progressively send into the combustion zone of giving of burner hearth by traveling-grate stoker, primary zone and burnt zone, slag falls into the pulp water pond then, the flue gas that furnace front gives the combustion zone is subjected to stopping of partition wall, most of particle and the rice husk that is burnt cinder drop on the traveling-grate stoker again and burn away, and flue gas is crossed other flue gas flue in the middle of drum under the negative pressure that air-introduced machine causes in partition wall and the burner hearth, economize coal gas, smoke pipe, deduster and tower water spray deduster, and enter air-introduced machine, by air-introduced machine flue gas is sent into water tank type smoke abatement device then, discharge by chimney at last.
The beneficial effects of the utility model are: rice husk burns in this improved horizontal chained fire grate packaged boiler, very desirable, neither can burn out the material flashboard, hopper is caught fire, and flue gas has been done repeatedly dedusting, almost there is not dust to discharge, rice husk is turned waste into wealth, improved environment again, eliminated hidden danger, and simple for structure, easy construction.
