Description

PECH JAROSLAV, HRADEC KRÁLOVÉ (54) The apparatus for charging gasification generators for the purpose of the invention is to improve the function of the upper closure of a coal-permeable vessel while increasing gas production. The apparatus consists of a double hopper above the coal transfer vessel, alternately connected to the reactor pressure space and the unpressurized vessel.

In the space of the connection of the angled leads (2) to the chamber (3) above the inlet of the coal transfer vessel (4), vertically movable closing plates (5) are connected at the lower edge by a crossbar (6) connected by a rod (7) (8).

(52) Int. C. 'C 10 J 3/30

The invention is applicable in power engineering for shaft furnaces, in particular for pressure gasification generators.

BACKGROUND OF THE INVENTION The present invention relates to a device for charging gasification generators operating at pressures of 0.5 to 15 MPa and solves them as perfectly as possible. function of the upper closure of the coal transfer vessel by achieving a high gas tightness.

There is known a device for charging gasification generators consisting of a double hopper of a container with chutes to the space above the coal transfer vessel. In each chute there is a horizontal plate slide with a linear actuator.

The disadvantage is that the closures do not work simultaneously, when one of the closures is delayed, the coal leakage continues in the respective downcomer and the gap between the seat and the closure in the transfer vessel is free of coal. If the pressure shut-off of the transfer vessel is not closed, beside the gas leakage to the generator station, the coal dust and gas mixture seat closure 1 is beaten and damaged, leading to shutdown of the device. Plant shutdowns result in the loss of a significant amount of gas produced.

In addition, the gap between the body and the slide plate causes dusting, coal dust discharge and contamination of the working environment of the generator station.

The above-mentioned drawbacks are eliminated by the gasification generator charging device according to the invention, consisting of a double hopper above the coal transfer vessel connected alternately to the reactor pressure space and a non-pressurized hopper. In the coal transfer vessel, vertically movable closure plates at the lower edge are connected by a cross-member connected by means of a rod to a rectilinear actuating member. Above the closing plates

2,232,173 are open pockets connected to the ceiling of the space above the entrance to the coal transfer vessel adjacent to the walls of the double hopper chute. The closing blankets are guided in guide slots located on the vertical walls of the chute.

The device according to the invention permits the simultaneous closure of the two downpipes, thereby interrupting the pouring of coal and the closure of the coal transfer vessel being closed against a clean seat and sealing against the gas. This greatly extends its service life. Reducing downtime will increase gas production. Also, the cost of repairing the closure and seats is lower.

An exemplary embodiment of the invention is shown schematically in the drawing. The double hopper 6 of the container is connected to the inclined downpipes 2 opening into the chamber 3 above the container 4 for transferring coal. . In the space of the opening of the downpipes 5 into the chamber 4 there are vertically movable closing plates 4 connected at the lower edge by a crossbar 6, which is connected by a rod 6 to a rectilinear actuating member. to the walls 11 of the chute 2 of the double hopper 6. The closing plates 4 are guided by continuous or discontinuous strips on the vertical walls of the chute 6. The wiring is not indicated in the figure.
