Detailed description of the invention
Basic conception of the present invention is, a kind of carrying method and feedway of High-temperature carbonization coal are provided, by arranging exhaust gear on buried scrapper conveyor, the steam of High-temperature carbonization coal generation in course of conveying and gas can be discharged from exhaust gear, both avoided producing airborne dust, gas and aqueous vapor can be made again to discharge, avoid the quality affecting product of coal.
Below in conjunction with drawings and the specific embodiments, High-temperature carbonization coal feedway of the present invention is described in detail.
See Fig. 1, the High-temperature carbonization coal feedway in the present embodiment comprises buried scrapper conveyor 1, and be arranged on the multiple spaced bag-type dust case 2 of buried scrapper conveyor 1 upper cover tapping, these bag-type dust casees 2 are arranged evenly and at intervals; Vibrator (not shown) is also provided with in bag-type dust case.Buried scrapper conveyor 1 is provided with entrance 11, and High-temperature carbonization coal from then on entrance 11 enters into buried scrapper conveyor 1.Bag-type dust case 2 is provided with import 21 and exhausr port 22, the inner chamber conducting of import 21 and buried scrapper conveyor 1, exhausr port 22 and extraneous conducting.
Wherein, each bag-type dust case is arranged along the interval, mass transport direction of high temperature carbonization feedway.
Buried scrapper conveyor, bag-type dust case all can select product of the prior art, and concrete structure this time repeats no more.
The outside of buried scrapper conveyor can coated adiabator layer, is greater than 100 DEG C to make dust cleaning case operating temperature.
The High-temperature carbonization coal carrying method of the present embodiment comprises:
High-temperature carbonization coal adopted buried scrapper conveyor 1 to carry, offer some holes at the upper cover of buried scrapper conveyor, this some holes installs bag-type dust case 2 additional, bag-type dust case 2 is spaced a distance setting.Wherein, the distance at interval is relevant to the water vapour content in buried scrapper conveyor, if the bag-type dust case interval arranged is too near, and water vapour content in buried scrapper conveyor is too little, then can cause waste, if and the interval arranged is too far away, and water vapour content is too large, then aqueous vapor can be caused to discharge in time, thus enter into the quality that product of coal affects product of coal, based on such consideration, the scheme of the present embodiment is: the water vapour content in buried scrapper conveyor is greater than 0.2 kilogram/m
3time, arrange and be interposed between in the scope of 2m ~ 3m between adjacent two exhaust gears; Water vapour content in buried scrapper conveyor is 0.2 kilogram/m
3time following, arrange between adjacent two exhaust gears and be interposed between in the scope of 5m ~ 7m.
In the present embodiment, bag-type dust case can replace with sludge box.
The workflow of the present embodiment is as follows:
Workflow: destructive distillation brown coal enter from buried scrapper conveyor one end, carry to the other end.Due to brown coal temperature higher (about 200 DEG C), so have steam and gas is constantly separated out.First be the gas that upper strata brown coal are separated out.Under the motion effect of scrapper conveyor, the brown coal being in bottom can ceaselessly move, and meanwhile, gas also can ceaselessly upwards be extruded.When gas and steam are separated out, the dust of fraction can be attached simultaneously.These gases and dust are after bag-type dust case, and dust is by Bag filter, and gas is discharged.Dust on cloth bag is fallen in scrapper conveyor under the effect of vibrator, and gas and steam take large calorimetric out of while discharging, and can reduce coal grain internal moisture and temperature.
Due to the existence of steam, for guaranteeing the normal work of dust cleaning case, at the outside coated one layer of heat preservation material layer of buried scrapper conveyor, be greater than 100 DEG C to make dust cleaning case operating temperature.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
