    A reactor for the anaerobic digestion of organic sludge and for the production of methane gas, comprises an essentially horizontal cylindrical vessel provided with an agitator rotating around an essentially horizontal shaft, an inlet for introducing the sludge to be digested at one end of said vessel, at its opposite end an outlet for removing the digested matter from the vessel and in the upper portion of the vessel an outlet/outlets for the recovery of methane gas. For returning the solids settled on the bottom of the vessel from the outlet end of the vessel to the inlet end of the vessel, the vessel comprises a channel connecting the outlet end of the vessel with the inlet end of the vessel and a device for guiding the solids to the front of the return channel and for their transport through the return channel by means of gas.

    The invention relates to anaerobic treatment of organic sewage sludge and methane production.
    The purpose of the invention is to increase the power of the reactor and its efficiency by providing the ability to control the amount of returned solids, regardless of the speed of the mixer.
    In FIG. I 'Reader shown, longitudinal section; FIG. .2 - section AA in FIG. I; in FIG. 3 is an embodiment of a reactor with a return pipe, a longitudinal section.
    The reactor contains a horizontal cylindrical tank 1 with a cylindrical jacket 2, a horizontal shaft 3 with blades 4, which is a mixer of the treated sludge. The shaft is installed at both its ends in bearings located in the end walls 5 and 6, and has a drive. On the wall 5 of the tank 1, there is a site for introducing combusted sludge with an inlet 7. On the opposite side of the tank on the end wall 6 there is a site for unloading the treated sludge with an outlet 8 and a methane removal unit in the upper part of the tank with an outlet 9. At the lower point of the outlet end of the tank 1, an exhaust tray 10 with an inclined bottom is installed to remove solid precipitating substances. The shaft 3 is hollow, in its inlet end holes 1 1 and 12 are made at a distance from one another. Inside the shaft is a slider 13, which overlaps these holes.
    At the outlet end of the reactor tank 1, there is a recirculation channel 14 connected to the end of the hollow shaft 3. The tray 10 has an inclined bottom 15 in which holes 16 are made, through which gas flows from the hole 9. The channel 14 communicates with its lower part 17 with the cavity of the tray 10 , in which a worm feeder 18 is installed, moving solids to the bottom of the tray. Channel 14 in the embodiment may be made in the form of a return pipe 19. Gas is supplied from the hole through a gas pipeline 20 having a compressor 21 and a valve 22 for regulating the gas flow and, respectively, for the amount of sludge transported by it. The returned sludge can be sent to the desired point of the tank using the slider 13 and through the holes 11 and 12 in the shaft 3. The return pipe 19 in the embodiment of the reactor 5 (Fig. 3) through the hole 23 is in communication with the cavity of the tank 1.
    The reactor operates as follows.
    The sludge to be burnt is fed in portions or continuously into the reactor through the inlet 7. The burnt sludge deposited on the bottom of the tank is transported to the tray 10, where it is transported through the hollow shaft 3 or by truck through the gas introduced through the holes 16 gate pipe 19. The shaft rotates continuously or periodically. Most of the treated sludge is removed through the outlet 8 in the end wall 6. The amount of sludge supplied for recirculation is controlled by valve 22 by acting on the gas stream.
    An advantage of the invention is the ability to control the amount of returned solids, regardless of the speed of the mixer — the substances are returned smoothly, 30 but their groups are not destroyed, and heavy particles (sand, etc.) are not returned. The reactor has a simple design, is easy to maintain, and its technical advantages provide high efficiency and increase its power.

    1 The invention relates to the anaerobic treatment of organic sludge waste and the production of methane. The purpose of the invention is to increase the reactor power and its efficiency by allowing the amount of solids returned to be controlled independently of the stirrer speed. FIG. 1 - longitudinal section is shown; in fig. .2 - section A-A in FIG. one; in fig. 3 shows an embodiment of a return tube reactor with a longitudinal section. The reactor contains a horizontal cylindrical tank 1 with a cylindrical jacket 2, a horizontal shaft 3 with blades A, which is an agitator of the treated sludge. The shaft is installed with both of its ends in under the hips located in the end walls 5 and 6, and has a drive. On the wall 5 of the reel of the sound 1 there is a combustion sludge injection unit with an inlet 7. On the opposite side of the tank, on the end wall 6, there is a discharged sludge discharge unit with an exhaust port 8 and a methane removal unit in the upper part of the tank with an exhaust port 9. At the bottom The outlet end of the tank 1 is fitted with an outlet tray 10 with an inclined bottom to remove solid precipitating substances. Shaft 3 is hollow, at its inlet end there are holes 11 and 12 spaced apart from one another. Inside the shaft is a slider 13, which overlaps these holes. At the outlet end of the tank 1 of the reactor there is a recirculation channel 14 connected to the end of the hollow shaft 3. Tray 10 has an inclined bottom 15 in which holes 16 are made, through which gas flows from hole 9. Channel 14 with its lower part 17 communicates with the cavity of the tray 10, in which a screw feeder 18 is installed, moving solids to the bottom of the tray. The channel 14 in the embodiment may be made in the form of a return pipe 19. Gas from the orifice is supplied through a gas pipeline 20 having a compressor 21 and a valve 22 for regulating the gas flow and accordingly for the amount of sludge transported by it. The returned sludge can be sent to 59 the desired point of the tank using the slider 13 and through the holes 11 and 12 in the shaft 3. The return pipe 19 in the embodiment of the reactor (Fig. 3) is connected through the hole 23 to the cavity of the tank 1. The reactor operates as follows. Combustible sludge is fed in portions or continuously into the reactor through inlet 7. Burned sludge deposited on the bottom of the tank is moved to tray 10, where it is transported to the charging part of the tank through the hollow shaft 3 or through the return pipe using gas introduced through the holes 16 19. The shaft rotates continuously or intermittently. Most of the treated sludge is removed through the outlet 8 in the end wall 6. The amount of sludge fed to the recirculation is controlled by the valve 22 by influencing the gas flow. An advantage of the invention is the ability to control the amount of solids returned, regardless of the speed of the agitator,: the substances are returned smoothly, their groups are not destroyed, and heavy particles (sand, etc.) are not returned. The reactor has a simple design, is easy to maintain, and its technical advantages provide high efficiency and increase its capacity. Claim 1. Reactor for anaerobic combustion of organic sludge and production of gaseous methane, containing a horizontal cylindrical tank, a horizontal shaft with a stirrer, an inlet for introducing burned sludge at one end of the tank, located at the opposite end of the tank, an outlet for removing the burnt material, and inlet a hole in the upper part of the methane removal tank, as well as a device for returning solids deposited on the bottom from the outlet end a reservoir in its inlet end, characterized in that, in order to increase the reactor power and the efficiency of action of
