Abstract

The invention discloses novel compound solar sludge drying equipment which belongs to the technical field of deep dehydration of sludge. In comparison with present sludge dehydration equipment, the equipment provided by the invention has the following advantages: a solar heat collector and a solar power system are additionally added; a crawler belt and a heating pipe are used to dry sludge; the structure is simple; and efficiency is high. According to the invention, a renewable clean energy, solar energy, is used as the main energy, thus saving a lot of energy. The solar heat collector has a simple structure and is convenient to install. The equipment is simple to operate. Water content of dried sludge is about 20-30%. The dried sludge can be used as a raw material of a novel energy to be recycled.

Description

technical field [0001] The invention belongs to the technical field of sludge deep dehydration, and in particular relates to a novel composite solar sludge drying equipment. Background technique [0002] The moisture content of the sludge after deep dehydration is generally 50-60%. Currently, most of the drying technologies on the market are steam evaporation dehydration, which consumes a lot of energy. There are also some solar sludge drying technologies that require the construction of huge transparent drying The room occupies a large area, and the heat loss is relatively large, and the operation and maintenance are complicated. Contents of the invention [0003] The purpose of this invention is to address the defects of the existing sludge drying technology, and propose a new type of composite solar sludge drying equipment, which can improve the efficiency of sludge drying, utilize renewable clean energy, and reduce the volume of sludge , reduce secondary pollution and...
