Sludge drying carbonization drying furnace heating control system

Abstract

The invention discloses a sludge drying carbonization drying furnace heating control system, which comprises a processing system and a heating system which are arranged in an upper and lower layered mode. The processing system internally comprises a first drying furnace, a second drying furnace, and a carbonization furnace, the heating system comprises a second combustion chamber and a biomass burner, the carbonization furnace communicates with a second pipeline for hot gas internal circulation, the second pipeline communicates with a first pipeline, and the second pipeline is provided with afan group used for controlling the flow rate of hot gas in the pipeline and forming a negative pressure environment for hot gas internal circulation, the carbonization furnace is provided with a looppipe communicating with the heating system, and the end opening parts of material discharging bins of the first drying furnace and the second drying furnace communicate with a deaeration device used for exhaust gas treatment. According to the sludge drying carbonization drying furnace heating control system, the negative pressure environment in the pipeline is generated through the fan group, thusrecycling of heat energy is realized, exhaust gas emission is reduced while the energy consumption loss is lowered, improving the production efficiency of an enterprise is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of drying and carbonization, in particular to a heat supply control system for a sludge drying and carbonization drying furnace. Background technique [0002] Most of the existing drying furnaces and carbonization furnaces adopt separate layouts, which cannot be integrated into the same system for collaborative use. At the same time, there is a large amount of heat loss during the operation of the drying furnace and carbonization furnace. Since the integrated integration cannot be realized, As a result, the heat exhausted by each furnace body cannot be shared reasonably, and the exhausted waste cannot be reasonably disposed of. The above problems are all defects in the prior art. In order to overcome the above defects, continue to search for a more efficient equipment system. Contents of the invention [0003] The object of the present invention is to provide a heat supply control system for sludge drying ...
