Pesticide waste residue fluidized bed incinerating process and pesticide waste residue fluidized bed incinerating device

Abstract

The invention provides a pesticide waste residue fluidized bed incinerating process and a pesticide waste residue fluidized bed incinerating device. The process comprises the following steps: charging pesticide waste residues into an incinerating device to incinerate at 900 DEG C-950 DEG C at pressure of minus 100-minus 200Pa; then charging smoke into a waste heat boiler to carry out heat exchange; leading the cooled smoke to be in contact with water and absorbing residual HCl and Cl2 in the smoke by alkali. The incinerating device comprises a fluidized bed incinerator body, wherein an explosive prevention door and an ammonia water spray gun are arranged on a sparse phase incinerating area; the lower part of a dense phase incinerating area is provided with a wind allotting plate, the lower part of the wind allotting plate is provided with a wind chamber, and the bottom end is provided with a residue discharge pipe; the top of the incinerator body is communicated with the upper part of a cyclone separator; the top of a center cylinder of the cyclone separator is connected with the top of a smoke channel at the tail part, and the bottom is communicated with the dense phase incinerating area of the incinerator body by a material return device. The invention can ensure the thorough incineration of pesticide waste residues, prevent secondary pollution and realize decontamination and recycling of wastes.

Description

technical field [0001] The invention relates to the reduction, harmlessness and resource utilization technology of industrial organic waste, and in particular to a fluidized bed incineration process and incineration device for pesticide waste residue. Background technique [0002] With the widespread application of pesticides, the pesticide industry has developed rapidly. The rapid expansion of pesticide factories and the rapid expansion of production scale make the output of pesticide residues also increase day by day. Pesticide residues are causing increasingly serious pollution to the environment, and the control of pesticide residue pollution has become a hot issue of widespread concern in society. my country is a big country of pesticide production. The existence of these problems has seriously affected the further development of my country's pesticide industry and hindered the improvement of the overall technical level of the pesticide industry and the core competitiv...

Problems solved by technology

[0004] There are many types and methods of solid waste incinerators. Chain furnaces, grate furnaces and rotary kilns are widely used in the incineration of solid materials. However, for pesticide waste, due to its special physical properties, it will soften when the temperature exceeds 90 ° C. , when it exceeds 200°C, it will be in a molten state, and if it is added to the above furnace type, it will cause melt flow, sticking and clogging.
