SU18600A1 - The method of loading pulp pulp, etc. boilers - Google Patents

Description

The proposed method for charging pulping and other moths is that, introduced from storage into the digester, chips in a sulphite or other pulp production process, is injected into the boiler with steam under pressure while being mixed or preliminarily mixed with cooking acid or lye and suction, located in the boiler, air.

In FIG. depicts the front view of the proposed device; FIG. 2 - the same, top view; FIG. 3-proposed device with distribution device; FIG. grates from above; FIG. 5 is the same side view.

To implement the proposed method, a device is used, consisting of a cylinder 2, which serves to introduce chips into the boiler and is equipped with a flange 1 and an annular steam pipe 3 with a pipe from which vertical, curved at the ends in one direction, downwardly inside the cylinder, pipes 4, 5 (figs. 1, 2), which end inside the cylinder at different heights. The cylinder 2 is inserted into the feed neck of the digester and rests on it with a flange 1. The pipe 3 is connected to the steam pipe, and the steam jets are directed along the bent pipes 4, 5 obliquely downwards. Cylinder 2

and the pipes 4, 5 entering into it can be given a form allowing to bring steam through one, and liquors through other pipes located, if necessary, at different levels. Injected into the cylinder 2, the chips are carried along by steam jets and introduced into the boiler in a swirling motion.

In order to distribute the chips evenly inside the cooking pot, a chip distributor consisting of a cone 6 facing upwards and connected to a cylindrical part constituting one piece with the cone is installed above or inside the cooking vessel (Fig. 3).

The bottom of the digester is provided with one or more openings connected to the suction device and used to suck air from the boiler. The holes for air suction and the holes for the release of the welded material are closed when the boiler is filled with folding or sliding grilles (Fig. 4), designed to prevent the holes from becoming clogged with chips. The grids are made entirely or partly from a material (wood) that can be cooked with chips and incorporated into the pulp. The grille consists of wooden, etc. planks ,.

hinged between themselves with the help of wooden pegs or wire pins (Fig. 4 and 5). The chips are mixed with the liquor used during cooking, before or during the loading of the digester.

The subject of the patent.

1. A method for charging pulping, etc. boilers, characterized in that the feed material (chips) supplied to the boiler necks is blown into the boiler by pressurized steam with a supply to impregnate the material used during the cooking of acid or lye, or without supply.

2. A device for carrying out the method specified in claim 1, characterized in that, in order to enthrall material loaded into the boiler, with steam

.Dilindra 2, inserted into the neck

The boiler and the flange 1 held on it are provided with an annular steam supply pipe 3, with pipes 4, 5 extending from it inside the cylinder downwards, the ends of which are bent in one direction and the bottom of the boiler is equipped with an opening connected to the suction device (Fig. 1 and 2 ).

3. With the device specified in clause 2, the application is: a) a distributor consisting of a cone b, in its lower part connected to the cylinder, worn on top of the annular steam supply pipe 3 of cylinder 2, or located inside it (Fig. 3) ; b) lattices covering the suction for air and exhaust for welded material openings in the bottom of the boiler, made in whole or in part from a material (wood) that is cooked together with the material being processed and is part of the latter;
