Abstract
The invention discloses a fuel for high temperature inflation burning in a porcelain granule rotary kiln, which is dry sawdust or rice husk. The invention uses the dry sawdust or the rice husk as the fuel for the high temperature inflation burning in the porcelain granule rotary kiln, and has the following advantages: on the one hand, when the sawdust or the rice husk is burnt, sulfides which are harmful to human body are not generated, air pollution is less, thus the sawdust or the rice husk is more environment-friendly; and on the other hand, the sawdust is foam sawdust of trees scattered down from the trees because of cutting during wood processing, the rice husk is a material separated in rice processing, the sawdust and the rice husk are rich in source and have very low material cost; in addition, the sawdust and the rice husk are products obtained directly in the wood processing and the rice processing by people, the rice husk is generally dry and can be used directly through simple processing, while partial 40 to 50 meshes of the sawdust is screened out and is processed (air-dried) simply. The processing cost can be negligible, and compared with pulverized coal, the comprehensive cost of the sawdust or the rice husk is only one-third of that of the pulverized coal.
Description
Technical field
The present invention relates to building material field, specifically is fuel for high temperature sintering and expanding of haydite rotary kiln.
Background technology
In recent years, the wall of China changed that policy deepens continuously, implementation dynamics is strengthened gradually, had built a great market space for thus the development of building material.Haydite is as a kind of building foundation material, and characteristics such as, insulation light with its body, sharp useless, environmental protection have been subjected to people and have paid attention to greatly.The light aggregate concrete hollow paving block of making as raw material with it, beam, plate etc. have become China's development novel wall material, replace the leading product of clay solid brick.
When haydite is produced, raw material is mixed stir earlier, then raw materials mixed is carried out granulation, form the material grain; To expect that again grain sends into rotary kiln, and carry out preheating oven dry, will carry out high temperature sintering and expanding through the high temperature sintering and expanding band that the material grain of preheating oven dry is delivered to rotary kiln then, naturally cooling just obtains haydite behind the material grain process high temperature sintering and expanding.During existing haydite was produced, the used fuel of high temperature sintering and expanding band is coal dust, on the one hand, can produce harmful sulfide during coal dust firing, and was comparatively serious to atmospheric pollution; On the other hand, under the situation of energy growing tension, the material cost of coal improves constantly, and coal dust to need by coal pulverizer raw coal to be milled to fineness be between the 130-120 order, the coal cost of processing is also higher, causes the comprehensive cost of coal dust higher.
Summary of the invention
The purpose of this invention is to provide the fuel for high temperature sintering and expanding of haydite rotary kiln that a kind of not only environmental protection but also comprehensive cost reduce greatly.
Technical scheme of the present invention is such: fuel for high temperature sintering and expanding of haydite rotary kiln, described fuel are exsiccant sawdust or husk.
The granularity of above-mentioned sawdust is the 40-50 order.
The water content of above-mentioned sawdust is lower than 6%.
The water content of above-mentioned husk is lower than 6%.
After adopting such scheme, as fuel for high temperature sintering and expanding of haydite rotary kiln, its beneficial effect is as follows: on the one hand, can not produce harmful sulfide when sawdust or husk fuel with exsiccant sawdust or husk in the present invention, less to the pollution that air causes, comparatively environmental protection; On the other hand, sawdust be when carrying out wood working because cutting and from the trees the foam shape wood chip of fallen trees itself, husk is the disengaging thing that rice adds man-hour, sawdust and husk source are abundant, material cost is extremely low, and, sawdust and husk all are the products that people directly obtain in carrying out the processing of timber or rice, husk generally is an exsiccant, only need simple processing just can directly use, part and simple processing (drying) that sawdust only need sieve out 40-50 order granularity get final product, and tooling cost can be ignored, compare with coal dust, the comprehensive cost of sawdust or husk only is 1/3rd of a coal dust.
Embodiment
Embodiment one:
Fuel for high temperature sintering and expanding of haydite rotary kiln of the present invention, described fuel are sawdust, and sawdust should dry and sieve before entering the storehouse, make the water content of sawdust be lower than 6%, and granularity is 50 orders.
Embodiment two:
Fuel for high temperature sintering and expanding of haydite rotary kiln of the present invention, described fuel are sawdust, and sawdust should dry and sieve before entering the storehouse, make the water content of sawdust be lower than 6%, and granularity is 45 orders.
Embodiment three:
Fuel for high temperature sintering and expanding of haydite rotary kiln of the present invention, described fuel are sawdust, and sawdust should dry and sieve before entering the storehouse, make the water content of sawdust be lower than 6%, and granularity is 40 orders.
Use sawdust as follows as the beneficial effect of fuel for high temperature sintering and expanding of haydite rotary kiln: on the one hand, can not produce harmful sulfide during sawdust fuel, less to the pollution that air causes, comparatively environmental protection; On the other hand, sawdust be when carrying out wood working because cutting and from the trees the foam shape wood chip of fallen trees itself, enrich in the source, material cost is extremely low; And sawdust is the product that people directly obtain in carrying out timber, and only need sieve out granularity is that 50 purposes part and simple processing (drying) get final product, and tooling cost can be ignored, and compares with coal dust, and the comprehensive cost of sawdust only is 1/3rd of a coal dust.
Embodiment four:
Fuel for high temperature sintering and expanding of haydite rotary kiln of the present invention, described fuel are husk, and husk should dry before entering the storehouse, make the water content of husk be lower than 6%.
Use husk as follows as the beneficial effect of fuel for high temperature sintering and expanding of haydite rotary kiln: on the one hand, can not produce harmful sulfide during husk fuel, less to the pollution that air causes, comparatively environmental protection; On the other hand, husk is the disengaging thing that rice adds man-hour, the husk source is abundant, and material cost is extremely low, and, husk is the product that people directly obtain in carrying out rice processing, husk generally is an exsiccant, only needs simple processing just can directly use, and tooling cost can be ignored, compare with coal dust, the comprehensive cost of husk only is 1/3rd of a coal dust.
