Integrated solid waste drying treatment system

Abstract

The invention discloses an integrated solid waste drying treatment system. The integrated solid waste drying treatment system comprises a rotary kiln device, a flue gas treatment device and a sewage treatment device, wherein the rotary kiln device is used for sintering and / or drying solid waste; the flue gas treatment device comprises an electrostatic dust collection mechanism, a desulfurization mechanism and an electric defogging mechanism; the electrostatic dust collection mechanism communicates with an air outlet of the rotary kiln device; the electrostatic dust collection mechanism, the desulfurization mechanism and the electric defogging mechanism communicate in series connection; and the sewage treatment device is connected to the electrostatic dust collection mechanism, the desulfurization mechanism and the electric defogging mechanism and is used for treating sewage which is discharged by the electrostatic dust collection mechanism, the desulfurization mechanism and the electric defogging mechanism. The integrated solid waste drying treatment system can effectively reduce the content of nitrogen oxides in emitted flue gas so as to reduce environmental pollution and water pollution and can reduce the production cost.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to an integrated solid waste drying treatment system. Background technique [0002] At present, when treating solid waste such as sludge, it is often completed by sintering the solid waste dryer. However, a large amount of flue gas will be generated during the sintering process of the solid waste dryer, and the flue gas is basically discharged directly into the atmosphere, and the flue gas contains a large amount of nitrogen oxides, and the direct emission of the flue gas will cause environmental damage. Serious pollution. In addition, when solid waste is disposed of, sewage that pollutes the environment is often produced. Contents of the invention [0003] Based on this, it is necessary to provide an integrated solid waste drying treatment system that can effectively reduce the content of nitrogen oxides in exhaust flue gas to reduce air pollution, water pollution and reduce produ...
