Abstract

The invention provides a hydraulic valve and a raw material conveying device and method for organic solid waste pyrolysis. The hydraulic valve comprises a valve body and a valve plate. The valve body comprises a feed port and a discharge port; the discharging port is larger than the feeding port, the valve plate is arranged in the valve body and located between the feeding port and the discharging port, and the surface, opposite to the discharging port, of the valve plate is larger than the surface, opposite to the feeding port, of the valve plate. The valve plate is used for controlling the communication area between the feeding port and the discharging port under the hydraulic action. According to the hydraulic valve, unique design is adopted, it is ensured that fabric filamentous garbage in raw materials cannot block the movement of the valve body, and the situation that a hydraulic valve plate is enlarged and prone to deformation is avoided. According to the raw material conveying device, material blockage of the hydraulic valve is avoided, the situation that a hydraulic valve plate is enlarged and prone to deformation is avoided, air tightness is achieved, efficient conveying of raw materials of the organic solid waste pyrolysis system is achieved, and operation and maintenance are easy.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, in particular to a hydraulic valve, a raw material conveying device and method for pyrolysis of organic solid waste garbage. Background technique [0002] The organic solid waste pyrolysis process aims at high-value utilization of solid waste. Based on the thermal decoupling coupled gasification technology, the chemical energy of solid waste is converted into gas, which can be used as fuel gas, heating, blending, power generation, etc. To achieve the purpose of effective harmlessness and reduction, at the same time, compared with direct incineration, it has a higher resource utilization capacity, which can greatly improve the flexibility of the project. The pyrolysis process requires control of the amount of oxygen entering the pyrolysis reactor, thus requiring a feed system suitable for the pyrolysis process of organic solid waste. [0003] For the raw material transportation of the or...
