An anaerobic pyrolysis system is a technology for treating organic waste, in which the organic waste is decomposed into gases that can be used for power generation or fuel production in an anoxic environment. High amounts of ash are produced during anaerobic cracking and in order to prevent ash build-up inside pipes and equipment, ash discharge valves need to be installed in the system to purge the ash periodically. An ash discharge valve is a device for controlling ash discharge in a system, typically mounted at the bottom or side of the system. When ash removal is desired, the ash discharge valve will open and allow ash to exit the system.

Referring to fig. 1, the present utility model proposes an ash discharger including:
The first ash valve 100, the first ash valve 100 is provided with a feed inlet 110 and a discharge outlet 120;
The second ash valve 200 is provided with a feed inlet 110 and a discharge outlet 120, the second ash valve 200 is connected with the first ash valve 100, and the feed inlet 110 of the second ash valve 200 is communicated with the discharge outlet 120 of the first ash valve 100;
the air intake pipe 300, the air intake pipe 300 communicates with one of the first and second dust discharge valves 100 and 200.
In the technical scheme that this embodiment adopted, through the mode of adopting and seting up intake pipe 300, let in sealing gas, like nitrogen gas through intake pipe 300 to the ash discharger inside, fill up the gap of ash discharge valve inside through sealing gas, prevent that atmospheric pressure from revealing in the anaerobic cracker, solve the current unstable technical problem of ash discharger sealed effect. Ash enters from the feed inlet 110 of the first ash discharge valve 100, enters from the discharge outlet 120 of the first ash discharge valve 100 into the second ash discharge valve 200, is finally discharged from the discharge outlet 120 of the second ash discharge valve 200, forms a seal in the first ash discharge valve 100 and the second ash discharge valve 200 respectively, and is filled with sealing gas through the air inlet pipe 300 into the whole ash discharge device, and a gap which is not sealed by the seal is sealed by the sealing gas, so that the whole sealing effect of the ash discharge device is improved. In addition, by adjusting the pressure of the sealing gas when the sealing gas is introduced, the gas flushing cleaning can be performed on the inside of the ash discharger through the gas inlet pipe 300, so that ash is prevented from accumulating in the inside of the ash discharger. Because the temperature of the anaerobic cracking furnace during operation is very high, one of the two ash discharging valves, which is close to the anaerobic cracking furnace, is assumed to be the first ash discharging valve 100, and the ash discharging valve has certain tightness, but under the influence of high temperature, the parts of the first ash discharging valve 100 can be deformed due to high temperature, so that the sealing effect is reduced, and the second ash discharging valve 200 is arranged, so that the situation can be corrected, when the sealing of the first ash discharging valve 100 fails, the sealing of the second ash discharging valve 200 is still effective, the air pressure leakage in the anaerobic cracking furnace can be prevented, and the maintenance of the first ash discharging valve 100 can be ensured after the anaerobic cracking furnace normally completes the operation of the stage.
Further, the ash discharger further comprises a sealing gasket 400, and the sealing gasket 400 is arranged at the joint of the first ash discharge valve 100 and the second ash discharger.
In the technical solution adopted in this embodiment, in order to prevent gas leakage at the junction of the first and second dust discharge valves 100 and 200, a gasket 400 is provided at the junction of the first and second dust discharge valves 100 and 200.
Further, referring to fig. 2, the first and/or second cinders 100, 200 are star-type valves. Specifically, the star valve includes a housing 510 and a stripper plate 520, the housing 510 is provided with a stripper chamber communicating the feed inlet 110 and the discharge outlet 120, the stripper plate 520 is rotatably disposed in the stripper chamber, and one end of the stripper plate 520 abuts against the inner wall of the housing 510.
In the technical solution adopted in this embodiment, compared with other types of ash discharging valves (such as a bottom ash discharging valve), the sealing effect of the star valve is better, so that both the first ash discharging valve 100 and the second ash discharging valve 200 are preferably star valves.
The sealing performance of the star valve is improved by the stripper plate 520 abutting against the inner wall of the shell 510, and the sealing effect of the star valve is further ensured to be stable by the material seal and the air seal. Because the temperature of anaerobic cracking furnace during operation is very high, high temperature can lead to being close to the stripper 520 in the star valve of anaerobic cracking furnace and take place crooked and then can't be with the inner wall butt of casing 510, lead to sealed effect variation, but keep away from the star valve of anaerobic cracking furnace can not be influenced by high temperature, and it still can provide sealedly for the ash discharger is whole, prevents that anaerobic cracking furnace from taking place gas leakage.
The number of the stripper plates 520 is six, the six stripper plates 520 are arranged at intervals, and the intervals between two adjacent stripper plates 520 are the same.
Six unloading are arranged in the discharger at the same intervals, so that the same unloading intervals and approximate unloading quantity of each time can be ensured during unloading, and the follow-up treatment of ash is facilitated. Of course, the number and spacing of the stripper plates 520 may also vary depending on the different operating environments.
Further, the first and second cinders 100 and 200 are detachably connected, in particular, screw-connected.
Because the ash discharger may cause poor sealing effect due to the high temperature influence of the anaerobic cracking furnace, the ash discharge valve needs to be periodically overhauled and maintained so as to avoid the problem of gas leakage of the anaerobic cracking furnace. For easy maintenance, the first and second cindervalves 100 and 200 are detachably connected, preferably by screw connection, and compared with the pin connection, the screw connection is convenient to detach, has a simple structure, and is reliable in connection, so that the screw connection is preferred.
The utility model also provides an anaerobic cracking furnace, which comprises the ash discharger, wherein the ash discharger is communicated with an ash outlet of the anaerobic cracking furnace, and the concrete structure of the ash discharger refers to the embodiment.
The foregoing description of the embodiments of the present utility model is merely an optional embodiment of the present utility model, and is not intended to limit the scope of the utility model, and all equivalent structural modifications made by the present utility model in the light of the present utility model, the description of which and the accompanying drawings, or direct/indirect application in other related technical fields are included in the scope of the utility model.
