Background
When the pharmaceutical industry carries out sewage treatment, a certain amount of waste and sludge are generated, and the waste and the sludge are called as 'medicine dregs' in the industry.
At present, the domestic treatment mode of the medicine dregs mainly comprises the following steps: burying, discarding and burning. The landfill mode can not radically reduce the pollution harm to the environment, and the soil can still be polluted by rainwater penetration; discarding the disposal requirements of the organic solid wastes which do not meet the requirements of the national relevant standards; the burning treatment increases the production cost of pharmaceutical enterprises, but the flue gas treatment facility can meet the environmental protection requirement.
The conventional incineration process flow is to store the herb residues in a collecting tank, and send the herb residues into an inlet of an incinerator through an inclined conveyor belt after drying.
In order to increase the treatment approach of the decoction dregs, some pharmaceutical factories transport the decoction dregs to other enterprises for treatment, and the enterprises include coal-fired power plants. The conventional process flow for treatment in a power plant still needs to be provided with a decoction dreg collecting tank and adopts an inclined conveying belt to convey the decoction dregs into an inlet of an incinerator. Because the dregs of a decoction are poor in tightness of conveying equipment in the conveying process, the stink is caused, people cannot tolerate the stink, the air is seriously polluted, the working environment is worsened, and the human health is damaged. The other treatment way is to gasify the medicine dregs to generate combustible gas and a small amount of tar, and then send the combustible gas into the hearth for combustion, although the problem of environmental pollution can be solved, the combustible gas contains the tar, the conveying temperature must be ensured to be higher than 200 ℃ in the fuel gas conveying process, otherwise the tar is condensed, the pipeline is blocked after long-term operation, and the tar is difficult to clean, and in addition, the initial investment and the operating cost of the project are greatly increased by gasification equipment.
Therefore, a medicine residue conveying system is urgently needed at present, and medicine residues can be conveyed to a hearth to be combusted conveniently and in an environment-friendly mode.
