Abstract

The invention discloses a sludge low temperature smoldering pyrolysis apparatus with automatic control and monitoring. The apparatus comprises control monitoring equipment, and one or more smolderingpyrolysis equipment, wherein the smoldering pyrolysis equipment comprises a pyrolysis furnace body and a sensing detection system, a closed feeder is arranged at the top of the pyrolysis furnace body,a slag discharge device is arranged at the bottom of the pyrolysis furnace body, and a carbon slag treatment device is equipped at a slag outlet of the slag discharge device; the bottom of the side wall of the pyrolysis furnace body is provided with a plurality of gas suction groups around the circumference, each gas suction group comprises a gas inlet and a gas outlet, the gas inlets are locatedabove the gas outlets, each gas inlet and the corresponding gas outlet are located at opposite side surfaces of the pyrolysis furnace body, an annular gas guiding pipe is arranged on the pyrolysis furnace body, each gas outlet communicates with the annular gas guiding pipe, and each gas inlet and each gas outlet are equipped with corresponding control valves; and a ventilation pipe is arranged onthe annular gas guiding pipe. According to the apparatus, the best smoldering effect is achieved, and monitoring of an operating state and a target position of each smoldering pyrolysis equipment isrealized by the control monitoring equipment.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to an automatic control and monitoring low-temperature smoldering pyrolysis device for sludge. Background technique [0002] Urban and industrial sludge must be treated in an environmentally friendly manner, and cannot be directly incinerated. The current gasifier, fluidized bed, or power plant treatment is all 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 the gas-liquid two-phase through the gas-liquid cyclone separator; cools the steam through the cooler to improve the gas-liquid separation efficiency; The reactor reduces the emission of harmful gases such as sulfur and nitrogen to achieve the purpose of protecting the environment. Chinese patent document CN10784285...
