Abstract

The invention discloses an automatic control and monitoring low-temperature smoldering pyrolysis device for sludge, which includes control and monitoring equipment, one or more smoldering pyrolysis equipment, and the smoldering pyrolysis equipment includes a pyrolysis furnace body and sensor Detection system, with a closed feeder on the top of the pyrolysis furnace body, a slag discharger at the bottom of the pyrolysis furnace body, and a carbon slag processor at the slag outlet of the slag discharger; on the side of the pyrolysis furnace body The bottom of the wall is provided with a plurality of suction gas groups around the circumference, and the suction gas groups include an air inlet and an air outlet. On the side, there is an annular air guide pipe on the pyrolysis furnace body, each air outlet is connected with the annular air guide pipe, and each air inlet and outlet is provided with a control valve; trachea; so as to achieve the best smoldering effect, and at the same time control the monitoring equipment to realize the monitoring of the operation status and target position of each smoldering pyrolysis equipment.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and particularly relates to an automatic control and monitoring sludge low-temperature smoldering pyrolysis device. Background technique [0002] Urban and industrial sludge must require environmental protection treatment and cannot be directly incinerated. Currently, the gasifier type, fluidized bed type or treatment in the power plant belongs to high temperature treatment, which will produce harmful substances such as dioxins and cause secondary pollution. . Chinese patent document CN207797070U discloses a micro-medium pressure smoldering treatment system for oily sludge, which mainly separates gas-liquid two phases through a gas-liquid cyclone; cools the steam through a cooler to improve the gas-liquid separation efficiency; The reactor reduces the emission of harmful gases such as sulfur and nitrogen, and achieves the purpose of protecting the environment. Chinese patent document C...
