The invention discloses a non-sticky furnace for chlor-alkali waste residue drying. The non-sticky furnace for chlor-alkali waste residue drying comprises a furnace body, wherein clapboards are arranged on the inner side wall of the furnace body; narrow lanes are arranged between the clapboards and the inner side wall of the furnace body; three to ten layers of heating pipes are horizontally arranged among the narrow lanes; three to ten strip holes are horizontally formed in the clapboards; arc-shaped cover plates are arranged on the outer sides of the strip holes; the number of the heating pipes is equal to the number of the strip holes; the height of the lower edge of each arc-shaped cover plate is lower than the height of each strip hole; the height of each heating pipe is lower than the height of each strip hole; an air storage tank is arranged on the outer side of the furnace body and communicates with the strip holes through pipelines; a feed inlet and an air outlet are formed above the furnace body; and a discharge hole is formed under the furnace body. The non-sticky furnace for chlor-alkali waste residue drying provided by the invention is simple and practical in structure, wet waste residues adhered to the inner wall can be quickly dehydrated due to the heating pipes clinging to the clapboards so as to fall off, and meanwhile, the waste residues adhered to the furnacewall are blown off through air blowing, so that the aim on non-sticking is achieved.
Description
Technical field [0001] The invention belongs to the technical field of chemical waste treatment, and specifically relates to a chlor-alkali waste residue drying non-stick furnace. Background technique [0002] The chemical industry is one of my country's important basic chemical industries. In particular, the PVC production process by the calcium carbide method and the ion-exchange membrane caustic soda process have gradually matured and the production volume has been large. However, chlor-alkali enterprises consume huge energy and resources, which not only bring economic benefits, but also bring a series of environmental problems, and produce a large amount of waste residues such as calcium carbide slag. [0003] With the development of science and technology and the continuous progress of science and technology, calcium carbide slag can be turned into a treasure. As a raw material to produce cement, the dry process technology is more mature. First, the calcium carbide slag is dr...
