Sludge heating device

Abstract

The invention relates to the technical field of sludge heating equipment, and provides a sludge heating device. The device includes a pre-electrolysis electromagnetic heater, which includes an electromagnetic heating tube. An inlet of the electromagnetic heater is connected through one side of the pre-electrolysis electromagnetic heater, and an outlet of the electromagnetic heater is connected through the other side of the pre-electrolysis electromagnetic heater. The two ends of the electromagnetic heating tube are respectively sealed and sleeved with a rear end cover and a front end cover. The device overcomes the defects in the prior art, is reasonable in design and compact in structure, solves the problems that a heating device in the prior art is poor in heating effect, low in efficiency and high in energy consumption and the sludge is liable to attach to the wall and coke. Through the simple combination of the structure, the sludge undergoes electrolysis to reduce the viscosity; meanwhile, through the stepwise gradient heating mode, heating efficiency and effect are increased, and wall attachment of the sludge is prevented. The device improves heating effect and brings convenience to following sludge treatment.

Description

technical field [0001] The invention relates to the technical field of sludge heating equipment, in particular to a sludge heating device. Background technique [0002] Sludge catalytic wet oxidation technology is a thorough reaction and energy-saving and stable process. It can oxidize and break the walls of various microorganisms in sludge, break chains of multi-chain organic matter while reducing heavy metal content, and greatly improve the dehydration of raw sludge. performance. [0003] The most important thing in the sludge catalytic wet oxidation technology is the heating device. Since the reaction requires high temperature (180-300°C), there are many problems in the large-scale equipment, which is difficult for industrial application. The current existing processes and systems have the following problems : [0004] 1. After the equipment is enlarged, the traditional jacket heating consumes too much energy, and the heating effect is poor. Using the jacket alone to he...
