Problems solved by technology
[0002] For the sludge roasting and drying industry, the moisture content of the material is uncertain, the shape is uneven, and the dust is large. However, in the traditional roasting process, the drying of the material is not complete, or the humidity of the drying Incomplete, so that the organic matter in the sludge cannot be burned, so it is difficult to meet the ideal environmental protection requirements for drying. Secondly, the use of electric heating consumes a lot of energy, and it is not clean and environmentally friendly, which increases the production cost of the enterprise virtually.

The invention discloses tunnel-type sludge roasting equipment and a process for treating sludge by virtue of the same. The equipment is mainly composed of a loader, a tunnel-type sludge roasting furnace, a middle conveyor, a cooler and a rear conveyor, wherein the whole equipment is in in-line arrangement; the sludge roasting furnace is provided with a preheating area, a heating area, a roasting area and a spontaneous combustion thermal-insulation area; and the roasted sludge particles enter the cooler; and the high-temperature sludge particles rapidly achieve a cooling effect through adequate utilization of a water circulation system. The equipment has the advantages of being simple in structure, reasonable in layout, and high in process controllability; process parameters can be adjusted according to the different humidity of sludge and a water content requirement after treatment; biomass environment-friendly particles or natural gas is mainly used as a heating energy; the characteristics of environment friendliness, safety and no pollution are achieved; and whole-course industrial automatic control is realized.
Description
technical field [0001] The present invention relates to various industrial technical fields such as sludge produced in industrial processes, metal and non-metallic ores, concentrates, and clay in the cement industry, and specifically relates to a tunnel-type sludge roasting equipment and a process for treating sludge using the equipment . Background technique [0002] For the sludge roasting and drying industry, the moisture content of the material is uncertain, the shape is uneven, and the dust is large. However, in the traditional roasting process, the drying of the material is not complete, or the humidity of the drying If it is not thorough, the organic matter in the sludge cannot be burned, so it is difficult to meet the ideal environmental protection requirements for drying. Secondly, the use of electric heating consumes a lot of energy, and it is not clean enough to be environmentally friendly, which virtually increases the production cost of the enterprise. Content...
