Description

A kind of device using furnace temperature drying bagasse
Technical field
It is specifically a kind of to be dried using furnace temperature the present invention relates to the preprocessing process and equipment that boiler uses biomass fuel The device of bagasse.
Background technology
The largest province of Guangxi as national cane sugar manufacture, existing 104, sugar refinery.The main dynamics equipment in sugar refinery is pot Stove, there are about 290, nearly all using bagasse as fuel.Since the combustion technology of bagasse stove falls behind, bagasse water content is big, bagasse combustion It burns not exclusively, the thermal efficiency of boiler is relatively low.To find out its cause, mainly there are following two problems：
1. since sugarcane fiber is longer, and easily mutually winding, the distribution in stove is also uneven, directly contributes bagasse It burns uneven；
2. the water content of bagasse is big, generally 50% or so, the temperature of strong influence burner hearth and bagasse burning are not The main reason for complete.
To solve the above-mentioned problems, many people make a general survey of domestic cane sugar manufacture enterprise in the new method for finding dry bagasse The method of dry bagasse is mainly the method using mechanical agitation cigarette pneumatic conveying drying, since sugarcane fiber is longer, and easily mutually Winding, the drying effect of bagasse is nor fine, never application.
Related open source literature reports the new method of some bagasses drying, does not also find that other open source literatures are reported so far A kind of device using furnace temperature drying bagasse in road.
Invention content
The object of the present invention is to provide a kind of moisture of rapid evaporation bagasse, the temperature of promotion bagasse, simple in structure, investments The bagasse pretreatment special equipment of province, specifically a kind of device using furnace temperature drying bagasse.
The invention is realized in this way bagasse is made to the separating treatment of long fibre and sugarcane marrow before it is dried, long fibre part Paper making raw material is done in packing, and after sugarcane marrow crushes, length is less than 6mm, does boiler oil；In addition bagasse is dried using using furnace temperature Device makees drying and dewatering processing to the bagasse after crushing, it is desirable that is reduced to 25%-40% from water content 50%.
A kind of above-mentioned device using furnace temperature drying bagasse send slag device, steam accumulator, bagasse drying box, sugarcane by spiral Slag feeder, steam discharge pipe, dregs removing device composition, it is characterized in that：The venetian blind type gas vent of steam accumulator is dried with bagasse Bagasse wall in case connects, and the water vapour being evaporated in bagasse enters steam accumulator across venetian blind type gas vent；Steam is received The top of storage sets multiple steam discharge pipes；The slag-drip opening of steam accumulator send similar spiral slag device, the sugarcane that steam is taken out of Slag recycles；The medial surface of bagasse drying box is connect with boiler furnace；Bagasse feeding machine is housed in the upper side of bagasse drying box； Dregs removing device is housed in the top of bagasse drying box；In the lower section of bagasse drying box slag device is sent equipped with spiral.
The bagasse that a kind of bagasse feeding machine of above-mentioned device using furnace temperature drying bagasse conveys is the sugarcane after crushing Marrow, for length within 6mm, function is that bagasse is made continually to be sent into bagasse drying box.
Louvered steam is made on a kind of steam accumulator right plate of above-mentioned device using furnace temperature drying bagasse to float Escape separated structure, ensures that bagasse flows down along wall, and steam flows into steam accumulator from gap.
It is hatch frame, length and sugarcane that a kind of spiral of above-mentioned device using furnace temperature drying bagasse, which send the top of slag device, The length of slag drying box is consistent.
A kind of above-mentioned device using furnace temperature drying bagasse, it is desirable that one face insulated wall of boiler is removed, bagasse drying box is installed, And ensure that the medial surface of bagasse drying box is connect with boiler furnace.
The present invention operation principle be：Bagasse will make the separating treatment of long fibre and sugarcane marrow, long fibre part before it is dried Paper making raw material is done in packing, and sugarcane marrow does boiler oil after crushing.During operation, bagasse feeding machine is endlessly by the bagasse after crushing It is sent into bagasse drying box, when bagasse fills bagasse drying box, forms bagasse wall, be exactly that one side is kept the temperature for furnace body Wall, for bagasse, the heat that burner hearth transmits increases bagasse temperature, when reaching the boiling point of moisture content in bagasse, may result in Moisture evaporation in bagasse generates a large amount of water vapour, at this point, water vapour will pass through bagasse and louvered steam vent, it is elegant into Enter steam accumulator, be then discharged in air from steam discharge pipe；Start the spiral below bagasse drying box and send slag device, it is dry Bagasse slide downwards, the bagasse that will be endlessly sent to boiler in slag device is sent to sow grass seeds by duster device into spiral；When bagasse is dried When bagasse movement is obstructed in case, starts dregs removing device and push bagasse downwards.
It is an advantage of the invention that：
(1) efficiency of utilization is high：Bagasse is heated using waste heat scattered outside boiler furnace, the result is that bagasse is rapidly done Dry and heating.
(2) simple in structure, reliable operation：Itself there is no moving component, it is simple in structure, without repair, reliable operation.
(3) it is easy for installation：One face insulated wall of boiler is removed, bagasse drying box is installed, it is easy for installation.
Description of the drawings
Fig. 1 is a kind of structure of the main view of device using furnace temperature drying bagasse of the present invention.
Fig. 2 is a kind of structure schematic side view of device using furnace temperature drying bagasse of the present invention.
As shown in Figure 1, a kind of device using furnace temperature drying bagasse send slag device 1, steam accumulator 2, bagasse to dry by spiral Dry case 3, bagasse feeding machine 4, steam discharge pipe 5, dregs removing device 6 form.
Specific embodiment
It elaborates below in conjunction with the accompanying drawings to the present invention.
As shown in Figure 1 the present invention structure of the main view in it can be seen that, it is a kind of using furnace temperature drying bagasse device by Spiral send slag device 1, steam accumulator 2, bagasse drying box 3, bagasse feeding machine 4, steam discharge pipe 5, dregs removing device 6 to form, special Sign is：The venetian blind type gas vent of steam accumulator 2 is connected with the bagasse wall in bagasse drying box 3, the water being evaporated in bagasse Steam enters steam accumulator 2 across venetian blind type gas vent；The top of steam accumulator 2 sets multiple steam discharge pipes 5；It steams The slag-drip opening of vapour collector 2 send similar spiral slag device 1, and the bagasse that steam is taken out of recycles；The medial surface and pot of bagasse drying box 3 Stove burner hearth connects；Bagasse feeding machine 4 is housed in the upper side of bagasse drying box 3；It is equipped in the top of bagasse drying box 3 and pushes away slag Device 6；In the lower section of bagasse drying box slag device 1 is sent equipped with spiral.
During operation, the bagasse after crushing is endlessly sent into bagasse drying box 3 by bagasse feeding machine 4, when bagasse fills During full bagasse drying box 3, bagasse wall is formd, is exactly a face insulated wall for furnace body, for bagasse, heat that burner hearth transmits Amount increases bagasse temperature, when reaching the boiling point of moisture content in bagasse, may result in moisture evaporation in bagasse, generates a large amount of water Steam, at this point, water vapour will pass through bagasse and louvered steam vent, it is elegant to enter steam accumulator 2 then from discharge of steam Pipe 5 is discharged in air；The spiral for starting 3 lower section of bagasse drying box send slag device 1, and the bagasse dried slides downwards, into spiral The bagasse that will be endlessly sent to boiler in slag device 1 is sent to sow grass seeds by duster device；When bagasse movement is obstructed in bagasse drying box 3, open Dynamic dregs removing device 6 pushes downwards bagasse.
