Problems solved by technology

[0004] At present, although there are some distiller's grains treatment processes in the prior art, there are still the following main problems: low processing efficiency, long time-consuming, not suitable for large-scale drying of distiller's grains, and the burning of distiller's grains in the incinerator, resulting in a large amount of dust in the flue gas , resulting in a high load on the follow-up purification device

Abstract

The invention relates to a distiller's grains processing system, comprising: a distiller's grains drying chamber, a pyrolysis device, a direct-fired boiler, a fluidized bed device, and a rotary air preheater. The melting point threat treatment system of distiller's grain incineration improves the safety factor and stability of the treatment process; solves the steam source of the brewing enterprise and reduces the operating cost of the enterprise; improves the energy utilization rate of the treatment system; reduces the operating load of the process flue gas purification system.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to the recycling treatment of distiller's grains, in particular to a distiller's grains treatment system. Background technique [0002] According to statistics, in 2015, my country's annual output of distiller's grains reached 42 million tons, which is a huge amount. The pollution of water resources by my country's light industry is quite serious, and the degree of pollution to the environment by the fermentation industry is second only to the paper industry. Faced with such a huge output of distiller's grains, if the treatment is not thorough and inappropriate, the distiller's grains will rot and deteriorate, wasting precious resources and polluting the environment. Therefore, the full and effective comprehensive utilization of distiller's grains can not only reduce environmental pollution, but also reduce costs, and realize the purpose of fully utilizing resources...
