Abstract

The invention puts forward a sludge drying ground heating device, which comprises a hot water pipe and a return pipe which are arranged at two sides of the drying ground. Steel radiators and PE heating pipes are connected between the hot water pipe at one side and the return pipe at the other side. The steel radiators are arranged within the drying ground of the upstream section during the sludge drying process. The PE heating pipes are arranged within the drying ground of the downstream section during the sludge drying process. In allusion to the characteristic that moisture evaporation velocity changes with sludge moisture content during the sludge drying process, the steel radiators are paved below sludge with high moisture content. By the utilization of the steel radiators' characteristic of high heat conductivity coefficient, supply of heat for sludge with high moisture content is increased, and evaporation of moisture is promoted. The PE heating pipes are paved below sludge with high moisture content. Loss of heat can be reduced under the precondition of satisfying heat supply.

Description

technical field [0001] The invention relates to the field of sludge drying equipment, in particular to a sludge drying ground heating device. Background technique [0002] During the sludge drying process, the water evaporation rate varies with the water content of the sludge. When the water content of the sludge is high, it is viscous. During the treatment process, the surface area and looseness of the sludge are poor, and water evaporation is difficult; The water in the sludge evaporates gradually, and the sludge is granular or powdery, with a large relative surface area, and the evaporation of water is relatively simple and fast. At present, the existing sludge drying ground heating device is generally provided with the same steel radiator throughout the ground, which has low heat utilization efficiency, causes serious heat loss, and relatively high manufacturing cost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomin...
