Description
Technical field
The utility model relates to CFB Incinerator technical field, is specifically related to a kind of molasses alcohol waste liquid Special circulation bed incinerator.
Background technology
China is important Sugar Production state and country of consumption, and sugar material is planted in China's agricultural economy and occupies critical role, and its output and the output value are only second to grain, oil plant, cotton, occupy the 4th.Cane sugar factory, in the production process taking sucrose as major product, all utilizes dry matter content to reach the molasses fermented production alcohol of byproduct of more than 50%, to enrich the industrial structure of cane sugar factory, increases the added value of cane sugar manufacture.But alcohol per ton, just 12 ~ 14 tons of waste liquids are produced, and molasses alcohol waste liquid is that a kind of concentration is high, color is dark, the organic wastewater that acidity is large, one of the most unmanageable two large waste water of generally acknowledging in the industry, very serious threat is caused to environment, people adopt physics in recent years, chemistry, biology and comprehensive treatment technique thereof, have received good regulation effect gradually, on the other hand, adapt to the demand of low-carbon economy, people more focus on reclaiming the useful resources such as natural colouring matter from molasses alcohol waste liquid while raising water treatment effect, molasses alcohol waste liquid is concentrated and burns biomass energyization to obtain green organic potassic fertilizer be the new way that domestic and international sugar manufacturing industry is sought simultaneously, and be more and more subject to the attention of insider, obtain the popularization of more and more sugar enterprise.But, because the calcium magnesium plasma concentration contained in molasses alcohol waste liquid is higher, in burning process, easily produces low melting point stickum, cause on boiler tube, occur coking, scale formation, be difficult to efficiency and the life-span of removing, affecting incinerator.Have employing boiler dedicated abroad, concentrating spent liquor is directly sprayed combustion process, but its price is very expensive, cost is too high-leveled and difficult to bear.Therefore, select to be applicable to the small investment of China's national situation, the alcohol effluent cleaning technology of high efficiency and technique, not only can solve the environmental issue that sugar refinery waste liquid causes, improve the economic benefit in sugar refinery, and the development of whole sugar manufacturing industry can be driven, therefore this problems demand solves.
Utility model content
For above Problems existing of the prior art, the utility model provides a kind of molasses alcohol waste liquid Special circulation bed incinerator.
The technical solution adopted in the utility model is:
A kind of molasses alcohol waste liquid Special circulation bed incinerator, it is characterized in that: comprise burner hearth, superheater, economizer, convection bank, air preheater, feeding-coal bucket, cloth wind system, chimney, the afterbody of described burner hearth connects superheater successively, convection bank, economizer, air preheater, drum is connected with above described burner hearth, the circulating line by burner hearth inside is provided with below drum, be connected with superheater one end by pipeline above described drum, the described superheater other end is connected with steam turbine by pipeline, described steam turbine connects generator, described economizer one end is connected with drum, the other end is connected with water tank, described water tank upper is provided with two pipelines, a pipeline is used for supplementing fresh water, another pipeline is connected with condenser, described condenser is connected with cooling tower, described cloth wind system arranges high-order bed and low level bed, and described high-order bed is connected with low-power fan, described low level bed is connected with high-power blower.
Preferably, described burner hearth is set to the burner hearth with heavy boiler setting.
Preferably, described burner hearth afterbody is provided with separating and feeding back device.
Preferably, air-introduced machine is provided with between described burner hearth afterbody and chimney.
Preferably, condensate pump is provided with between described water tank and condenser.
Preferably, described condenser bottom and cooling tower lower connection pipe road are provided with water circulating pump.
Preferably, feed pump is provided with between described economizer and water tank.
Preferably, described high-order bed and low level bed all adopt stainless steel material to make.
The beneficial effects of the utility model are:
This molasses alcohol waste liquid Special circulation bed incinerator have employed height bed technique:
1. height bed technique: low level height of bed wind speed, the low wind speed of high-order bed, realize large or fine granule shunting material inner circulation fluidized, pipe laying be located at only have fine grained, low wind speed high-order bed in, not easy to wear.
2. close low level bed, can meet and run under the underload of pole.
3. high sunken bed shunting, makes fine grained in its stop at emulsion zone of low speed bed interior prolongation the time.
Wherein, this equipment changes the direct combustion system of traditional single concentrating spent liquor, and the mixed oil shale abundant with Maoming area, improves efficiency of combustion, prevent tube coking.Before the high-order bed of this equipment, 4 nozzles carried on the back by wall paper, the alcohol effluent being 65 through concentrated brix sprays into through nozzle, fully mix with oil shale material a large amount of above burner hearth, in order to absorb concentrated solution burning liberated heat, side wall is arranged in the ascent stage, centre and fin panel casing, by suitably increasing excess air, alcohol effluent can be made to burn completely, can ensure that oil shale grain has enough oxygen combustions at floater, therefore there will not be coking situation on heating surface, reduce blowing out deashing number of times, because this type of furnace has the ability from deashing, therefore do not need soot blower.
