Description

The invention relates to shaft type furnaces for the charring of algae, with preliminary drying 1 | 1 and 1 gases flowing in the upper part of the furnace. In the proposed furnace, the furnace is installed inside the shaft and is provided with a vault, above which there is a muffle chamber for the algae that descend from above. The cavity of the aforementioned arch is communicated with a chamber located under the muffle chamber and having outlet openings for flue gases into the cavity between the shaft and the walls of the chamber.

 In FIG. 1 shows a section along the line KL in FIG. 2; FIG. 2 is a section through FE in FIG. one; FIG. 3-HH in FIG. 1; FIG. 4-by AA in FIG. one; FIG. 5-by BB in FIG. one; FIG. 6-BB in FIG. one.

The proposed furnace consists of three main parts: the firebox /, the muffle chamber 12 for charring algae and zone 3 for drying them.

The furnace / is installed inside the shaft and is provided with a vault, in the upper part of which there is a fiery span 2 for ejection of flue gases and two cast-iron plates 19, inserted one at a time in the side walls of the vault.

Muffle chamber 12 occupies the entire lower half of the furnace from the damper gates 10 at the top to the coal boxes 17 below. It separates from drying zone 3.

(163)

four iron gates and a vault, on which there is a chamber 6 of the dryer.

In the back of the roof there are four gas windows 13 for the release of volatile algal charring products into the chimney.

Fire chamber roof / is connected to the side walls of the kiln with bridges into the brick on the edge, forming a grid that serves, on the one hand, to hold non-carbonated algae, and on the other, to strengthen the roof of the furnace 7. Below the grids, chamber 12 is narrowed iron slides 16, separating them from iron drawers 17, for accepting algal coal.

Each coal separator 15 in the front wall of the furnace, directly under the lintels, has a leveling window, tightly closed by cleaning doors or view doors, not shown in the drawing.

In the side walls of the furnace, against the center of the chamber 72, when laying the furnace, one hole should be made in case of internal repairs, size 50 С.ИХ40 cm, followed by laying them with bricks and external greasing with clay.

The drying zone 3 occupies the upper half of the furnace and in the middle has a chamber 6 with a flame window 7 and four arched openings 9 for the emission of gases

into the dryer and the dryer with overturning iron gratings 5, divided by brick walls into four parts corresponding to four gateways and four overturning gratings, as well as loading 4 and cm3 holes and (doors).

The proposed kiln operates as follows: raw algae, partially dried on tilting grids, are dumped onto the damper gate W and dried there to a completely dry condition. When on the gates you accumulate a layer of dry water: tall leaves to tilting grids, the gates are opened by pushing them into the arched openings 9 of the evaporator and the algae are dumped into the chamber 12 on the heated arch of the firebox.

Algae are charred without air. If necessary, air can be supplied through the leveling holes of the coal dividers 15.

Partially or even completely carbonized algae, falling down through the brick grate, are calcined in the coal separators 15 and the resulting coal is dumped through the carbon separator gate onto the removable iron lattices of the coal boxes 17 to remove stones and to periodically unload

tightly closed iron or brick stainers for cooling.

The flue gases from the furnace / are directed through / flaming span 2 to the vertical chimney, from there through the fire window 7 to chamber 6, and from the latter, through the arched openings 9 and the layer of algae in the dryer to the pipe.

The combustible products of charring algae are sucked through the gas spans 13 into the vertical chimney with furnace gases of higher temperature, burned in their flames and go along with them to dry the algae.

Predgett invention.

A shaft-type furnace for charring algae, in which drying of algae passed through them in the upper part of the furnace with flue gases is used, characterized in that the furnace / is installed inside the mine and provided with a vault, which has a muffle chamber 12 for descending algae from above, the cavity the vault communicates with the chamber 6 located above the chamber 12 and having outlet openings for flue gases into the cavity between the mandrel and the walls of the chamber.
