Abstract
The present invention relates to material drier including heat source and deduster, and features that the heat source is a rotary kiln. The drier is connected through an air inlet pipe to the tail gas exhaust pipe of the rotary kiln, and connected through a draft pipe to the deduster. The present invention is superior in that by means of the cooperation of the rotary kiln and the deduster, no coal and no electricity stoving is realized, and the present invention has high stoving quality capable of stoving white material, stoved material to replace humidifying material with lowered cost, and simultaneous calcining, stoving and dedusting to save resource.
Description
(1) technical field
The present invention relates to the drying plant of material, the dryer that utilizes the waste heat of external heat source to dry specifically.
(2) background technology
The rotary kiln of calcination cement slurry will produce a large amount of waste heats and dust in the calcination process at present.In order to make the tail gas can qualified discharge, must install dust arrester installation additional.Because rotary kiln discharge tail gas temperature is very high, therefore between rotary kiln and dust arrester installation, also humidifying equipment to be installed.Large-sized rotary kiln generally uses conditioning Tower, and small-sized rotary kiln uses multitube cooler.Rotary kiln needs the cooling device investment at first stage of construction thus.And when operation, to use cooling water, also to increase the operating cost investment.The heat that it produced is but by slatterning in vain.
Employed dryers such as present drying fuel, cement slurry or slag, thermal source is mainly from the intrinsic thermal source generating means of body itself, and generally the fuel that uses is moulded coal.Coal is as a kind of non-renewable energy resources, and its reserves are fewer and feweri, because the fast development of domestic economy, the bunker coal price is soaring again and again.Dryer except that using fuel, also will use the blower fan consumed power in running, at present in the also soaring process of electricity price.So its operating cost also is very high.
China Patent No. is 942037162, name is called in " white cement clinker energy saving baking device ", the waste heat that has utilized rotary kiln to produce, with heat with take out, air-supply arrangement delivers in the dryer, uses fuel in the drying course thereby saved.The device but this device also will increase electric power in running in addition, institute does not reduce to operating cost lower.
(3) technology contents
The object of the present invention is to provide and a kind ofly need not use fuel and electric power, can dry the tower drier of material.
For realizing above-mentioned purpose, the present invention is according to following technical scheme.This tower drier comprises thermal source, dust arrester installation, and described thermal source is from rotary kiln, and dryer is connected with the tail gas discharging pipe of rotary kiln through blast pipe, and dryer is connected with dust arrester installation through induced duct.
On the top of dryer the charging airlock is set.
Level detector is arranged on the dryer bottom.
The place further increases the variant-frequency vibration device at the dryer discharging opening.
Further increase thermometric or hygrostat and feeding switching device shifter at dryer discharging opening place.
On the induced duct of connection dryer and dust arrester the thermometric pressure tester is set.
Superior part of the present invention is:
1. utilization and rotary kiln and cooperating of gathering dust and be provided with realizes no coal, do not have the electricity oven dry;
2. the assurance dries quantity particularly can be dried white mass;
3. with oven dry material substitution humidifying equipment, joint cost of investment and operating cost;
4. owing to saved humidifying equipment, can save occupation of land;
5. calcination, dry, gather dust and carry out simultaneously, resource can be shared to greatest extent;
6. the material after the oven dry can farthest improve its mill efficiency.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
(5) specific embodiment
Agent structure of the present invention is referring to accompanying drawing.It comprises that thermal source partly is rotary kiln 1, dust arrester installation 3, and its improvement is that conditioning Tower is replaced to baking machine 4, and by blast pipe 5 and induced duct 6 dryer 4, rotary kiln 1 is coupled together with dust arrester installation 3.Whole system is in case work, under the effect of blower fan, the waste heat tail gas of rotary kiln 1 discharging is inhaled in the dryer by blast pipe 5 in dust arrester installation 3, material is dried, and gas that dryer 4 is discharged and dust enter into dust arrester installation 3 dedustings by induced duct 6.Three kinds of equipment are used, and promptly can use the thermal source part in the alternative former dryer of rotary kiln thermal source, can substitute the blower fan and the dust removal part of former dryer again with dust arrester installation, and it is minimum that coal consumption, power consumption are reduced to, and finally reduced the operating cost of system.
In order to improve the utilization rate of heat, be provided with charging airlock 7 on the top of dryer 4.Material level device 8,9 is arranged on the bottom of dryer.If after the dryer charging, do not have airlock, a part of thermal source can be discharged from charging, promptly causes waste can cause the pollution of dust to environment again.After having increased airlock, can close charging aperture automatically after the material input.
Because this dryer is slightly different with the oven dry principle of present known dryer, in order to improve the thermal efficiency, what known technology adopted is to provide thermal source from the bottom, the material level device is positioned at dryer top, just can make heat make full use of and guarantee that material is fully dry when having only in material is full of the body chamber.And this dryer is a process from dryer owing to the tail gas of thermal source from rotary kiln 1, and is too full if material enriches, unfavorable to device for reducing dust 3 work on the contrary.So the present invention is arranged on material level device 8,9 bottom of dryer and has further increased variant-frequency vibration device 10 at discharging opening 2 places of dryer.Principle is if material and material level device 9 places or be lower than herein owing to be negative pressure in the machine, can make extraneous cold air enter and be unfavorable in the machine drying again.If being positioned at material level device 8 places, material can make into hot gas amount minimizing again.Therefore, further increase variant-frequency vibration device 10 at dryer 4 discharging openings 2 places.When material and level detector 9 maintains an equal level, its signal is sent to automaton, and discharging speed is accelerated in the frequency conversion of prompting frequency converter.When material and level detector 8 maintains an equal level, its signal is sent to automaton, and the frequency conversion of prompting frequency converter reduces discharging speed.
2 places further increase thermometric or hygrostat 11 and feeding switching device shifter 12 at dryer 4 discharging openings, purpose is to detect institute and goes out material and whether reach the oven dry standard, its signal is sent to automaton, the action of prompting switching device shifter, or send oven dry in the dryer again back to, or directly deliver to conveyer.
