Continuous feeding sludge decoupling gasification furnace

Abstract

The invention discloses a continuous feeding sludge decoupling gasification furnace which comprises a shell, a feeding pipe, a funnel, a motor, a pushing plate and a connecting rod. The feeding pipe is fixedly arranged above the shell, the funnel is fixedly arranged at the top of the feeding pipe, an inner groove is formed in the feeding pipe, the motor is arranged on the left side in the feeding pipe, the pushing plate is fixedly connected to the front end of the motor, and the connecting rod is welded to the front end of the pushing plate. An upper pipe sleeve and a lower pipe sleeve are rotationally installed in the shell, and fire grates are arranged below the upper pipe sleeve and the lower pipe sleeve correspondingly. In order to solve the problem that the contents of nitrogen-containing compounds and tar in gasified synthesis gas are high generally in a traditional gasification furnace, the gasification furnace device relieves the coupling reaction of pyrolysis and gasification, so that the contents of nitrogen-containing compounds and tar in products are effectively reduced, exploration of a generation mechanism of the nitrogen-containing compounds is facilitated, and waste heat is reasonably utilized to improve efficiency.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a continuously fed sludge decoupling gasifier. Background technique [0002] With the continuous advancement of urbanization in my country and the gradual increase in water environment governance, sludge has become one of the major environmental problems facing our country. Contrary to the continuous increasing trend of sludge production, the phenomenon of "heavy water and light mud" has long existed in my country's sewage treatment process, and the effective treatment rate of sludge is still very low. Generally speaking, traditional sanitary landfill, land use and incineration, etc. Sludge disposal technology is gradually encountering a bottleneck in industrial promotion and development due to limitations in in-depth control of pollutant discharge and further improvement of energy utilization efficiency. In contrast, gasification is one of the most widely concerned rout...
