Efficient energy-saving environment-friendly intelligent drying kiln

Abstract

The invention relates to an efficient energy-saving environment-friendly intelligent drying kiln which comprises a drying kiln body, a hot air supply flue gas furnace and a hot air circulation system. The efficient energy-saving environment-friendly intelligent drying kiln is characterized in that the hot air supply flue gas furnace is a full-automatic energy-saving environment-friendly biomass hot flue gas furnace. The hot air circulation system comprises an injection pipe device, a main air supply pipe, a group of branch air supply pipes, a group of branch exhaust pipes and a main exhaust pipe, wherein the injection pipe device is communicated with a furnace flue gas outlet of the biomass hot flue gas furnace; the main air supply pipe is communicated with the injection pipe device; the group of branch air supply pipes and the group of branch exhaust pipes are arranged on two sides of the drying kiln body respectively; and the main exhaust pipe is arranged on the outer side of the drying kiln body and is communicated with the group of branch exhaust pipes. A temperature detector is arranged in the main air supply pipe, and the temperature detector and the full-automatic energy-saving environment-friendly biomass hot flue gas furnace are connected with an intelligent control device. The efficient energy-saving environment-friendly intelligent drying kiln has the advantages that biomass waste materials are utilized to serve as a heat source, flue gas can be utilized in a circulated mode, and the efficient energy-saving environment-friendly intelligent drying kiln not only is low in cost, but also saves energy and protects the environment.

Description

technical field [0001] The invention belongs to the technical field of drying kilns, in particular to an intelligent drying kiln with high efficiency, energy saving and environmental protection. Background technique [0002] At present, traditional drying furnaces use direct coal, gas generators and electricity as heat sources, and direct hot air supply and direct exhaust air are used in the kiln. Taking the treatment of magnesia carbon bricks as an example, it is generally necessary to process a kiln. More than 16 hours, in addition to wasting energy and high operating costs, but also because the waste flue gas discharged from coal and gas generators contains a large amount of harmful components such as sulfur dioxide, hydrogen sulfide, and nitrate, which will cause great pollution to the environment. These pollutions, in addition to accounting for a large amount of site and treatment equipment funds, will also pay a large amount of operating costs. Contents of the invent...
