SU65220A1 - A device for the movement of combustible shale and other bituminous fuels - Google Patents

Description

Sewing of combustible shales and other bituminous fuels (peat, bogheds, sapropel, brown coal) is extremely important for household use, as it allows a large increase in fuel resources. The presence of oil and the increase in production from year to year of the latter does not in the least diminish the role and importance of the production of artificial liquids, including fuels, including those based on the beveling of bituminous fuels and especially shale oil

The shale industry of shale still developed in the main way along the path of the construction of the liver with internal heating, namely: tonic and. silos with forced multiple post-zone circulation of coolant and gas generators with shwelshakta. These cures largely satisfy the requirements of shale embossing technology, although they do not have any shortcomings. Since tunnel furnaces are very difficult to operate, their heaters require frequent cleaning of coke deposited in pipes and frequent repairs during burning.

The highly ash semi-coke obtained as a solid residue does not find the used one and goes to the dump. The shaft furnaces without repeated circulation of the shlyugaz give a vapor-gas mixture, strongly diluted with a generator basin, which fits south; due to mechanical crushing and abrasion of pieces of slate when passing through the mine and zatvo.ry separate zones.

The proposed device For the filing of combustible shale and other bituminous fuels is aimed at ensuring the continuity and maximum automation of the process and at eliminating the air heater, while retaining multiple poson forced circulating. pshyulygaza with all u muster the last.

The proposed device is based on the use of an installation known in itself with a tunnel oven equipped with

a mechanical chip lattice divided into several zones, a layer of fuel in each of which passes a gaseous coolant heated to different temperatures, the afterburning of the solid residue is carried out in the gas generator:.

In such installations, the heating medium is usually heated by burning a combustible gas over a layer of fuel or by circulating a radiator located above the belt.

From the above-mentioned known installations, the proposed device is different: those: M, chuyu, in order to regulate the TieiMnepaTypbi heat carrier in each zone of the tunnel, treat the mixing chambers to mix the heating medium with the hot floor from the gas generator. Mixing chambers are made in the form of ejectors. To regulate the flow of hot gases entering the mixing chambers, thermostats are added.

In FIG. 1 shows a schematic section of the proposed device, FIG. 2 is a section through a grid and a communication circuit for circulating a heat transfer fluid; FIG. 3-: a section along AB of FIG. 2 w of FIG. 4-section CD of FIG. 3

The fuel to be quilted, for example, slate, is a skip rider (not shown) OR1 by any other W3MOM fur is fed into the bunker 7, from which it goes to the chain grille 2. Pro | Xd over (gass) .1 CI. , 6, a layer of slate "several pai3 is produced" by an aggregate pulp, giving away volatility to a semi-coke, which enters the gas generator 3 for additional gas or afterburning.

Above the chain grate 2 there are mixing chambers S, into the tubes through pipe 10 with an exhauster 12, a carrier filled with resin is fed, and a 14 ° amp. 13 - heated gases from the gas generator 5. The temperature of those hot cells is regulated by gates / 5 by means of more or less additional addition of hot gases. The sliders are controlled by thermoregulators with heat contacts located, for example, in boxes 4, 5, 6.

The outlet pipes 9 of the mixing chambers 5 are arranged against the gas suction boxes 4, 5, 6, due to which the working section of the lattice 2 is expanded into a number of temperature zones. Instead of one common exhauster 12, a separate exhauster can be used for each such ZOVA.

Excess spoil gas is directed to condensation through the pipe.

The shale drier can be carried out either in the first zone (with appropriate temperature control), or in the bunker /, where for this purpose the coolant is fed from channel 14, diluted to the proper temperature with circulating gas, the excess of which is removed to the atmosphere.
