Abstract

The utility model relates to a bagasse drying tower with a tail smoke suspension-type used for drying the bagasse by making use of the tail smoke of boilers before a cane sugar factory takes the bagasse as fuel of the boilers, which is characterized in that two cyclone separating devices are arranged, wherein, an exit of the cyclone separating device which is connected with an entrance of the boiler tail smoke is connected to an entrance of the other cyclone separating device through a drier drum. A bagasse feeding hop is arranged on the drier drum. A first cyclone separating device is used for separating ash in the boiler tail smoke and clean smoke gas is obtained. The bagasse is dried in the drier drum and the dried bagasse is sent to a second cyclone separating device for separating. The utility model has the advantages of simple equipment, few operating trouble, long service life and large drying area, thereby having good drying effect and high economic benefit.

Description

The floated bagasse drying tower of tail cigarette

Technical field

The utility model relates to a kind of cane sugar factory and utilizes during as boiler oil boiler tail cigarette that bagasse is carried out the dry floated bagasse tower of tail cigarette with bagasse earlier.

Background technology

With the sugarcane is sugar refinery of raw material, and the bagasse some is used for doing boiler oil and uses, and another partly is used for the raw material of papermaking, fiberboard.The colliery energy prices are more and more higher now, concede the land to forestry, and the cry of the protection woods is more and more higher.The raw material of cardboard industry more and more relies on bagasse.Adverse consequences such as and its water content is up to 48-52% behind the cane milling, and the bagasse that contains so many moisture content can cause the boiler output deficiency when going into the stove burning, and efficiency of combustion is low: the part energy that (1) takies boiler evaporates moisture content, has wasted the energy.(2) reduce the boiler combustion temperature, cause incomplete combustion.(3) burning position is reduced on the fire grate, causes banking fire.And had part sugar refinery to use flue gas negative pressure bagasse drying system before more than ten years, though use this system to obtain certain effect, but obviously exist the device structure complexity, pipeline is long, bagasse is to use the flue gas negative pressure transportation at pipeline, serious wear, the pipeline inner wall unstability easily that is worn behind the attenuate.Therefore be eliminated.

Summary of the invention

The purpose of the utility model technology provides a kind of employing boiler tail cigarette as drying source, extracts the tail cigarette with blower fan, and the tail cigarette enters drying tower after cyclone separator separates cigarette ash, and the tail cigarette holds up unsettled drying to bagasse, separates bagasse with cyclone separator then.Equipment is simple, and operation troubles is few, long service life, and drying area is big, is that drying effect is good therefore, the floated bagasse tower of the tail cigarette that economic benefit is high.

Solution of the present utility model is like this: design has two cyclone separators, the cyclone separator outlet that wherein connects boiler tail cigarette inlet is connected to the inlet of another cyclone separator by drying, on drying, have the bagasse material-falling hopper, utilize first cyclone separator that the cigarette ash in the boiler tail cigarette is separated, obtain clean flue gas, in drying, bagasse is carried out drying, more dried bagasse is sent into second cyclone separator and separated bagasse.

The equipment that the utility model has the advantages that is simple, and operation troubles is few, long service life, and drying area is big, is that drying effect is good therefore, the economic benefit height.

Description of drawings

Accompanying drawing is embodiment of the present utility model.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is A-A cutaway views in the accompanying drawing 1.

The specific embodiment

The utility model includes 1 towards grey sealed cistern, 2 separator tail pipes, 3 cyclone separators, 4 boiler tail cigarettes inlet, 5 exhaust gases passes, 6 spray slag wind are chewed and airduct 7 dryings, 8 passages, 9 spray slag airducts, 10 exhanst gas outlets, 11 bagasse cyclone separators, 12 forms, 13 discharge buckets, 14 bagasses outlet discharge device, 15 bagasse adjustable plates, 16 holes or form, 17 instrumentation taps, 18 drying tower arc distribution bodies, 19 bagasse inlets, 20, discharge device, 21 bagasse material-falling hoppers, 22 forms, 23 smoke inlets.

Present embodiment has two cyclone separators, and the cyclone separator 3 that wherein connects boiler tail cigarette inlet 4 exports the inlet that is connected to cyclone separator 11 by drying 7, has bagasse material-falling hopper 21 on drying 7; Drying 7 is vertical shapes; Bagasse material-falling hopper 21 is to be located at drying 7 lower ends; In drying 7, be positioned at the bagasse adjustable plate 15 that bagasse material-falling hopper 21 places are equipped with swing.

Be connected with separator tail pipe 2 with cyclone separator 4 lower ends; Described separator tail pipe 2 is to stretch in grey sealed cistern 1.

The utility model operation principle is: boiler tail cigarette is sent inlet 4 to by blower fan, the tail cigarette is isolated cigarette ash in cyclone separator 3, cigarette ash is taken away cigarette ash by water because deadweight is fallen in grey sealed cistern 1 by tail pipe 2, tail pipe 2 extend in the water, plays sealing function; Clean flue gas enters smoke inlet 23 by exhaust gases passes 5; Bagasse 19 enters discharge device 20 from entering the mouth, and the flue gas that bagasse is entered in drying 7 holds up to suspend and moves upward, and carries out drying in flow process.When bagasse arrives the top of drying 7, enter bagasse cyclone separating tube 11 by passage 8, have spray slag wind to chew 6 on passage and help to send bagasse to advance, bagasse rotates separation in cylinder 11, wind and steam are discharged aerial from exporting 10 by the air-introduced machine extraction; Dried bagasse is fallen discharge bucket 13, is discharged by outlet discharge device 14.In order to obtain effect preferably, in the bagasse porch adjustable plate 15 is installed, the drying bottom is made into circular arc 18, connects measuring instrument 17 in the position that deposits bagasse easily, also has manhole or

form

12,16,22 simultaneously.

When
