Biological drying system

Abstract

The invention discloses a biological drying system which comprises a biological drying tank and a biological drying all-in-one machine, the biological drying tank is provided with a feeding end, a drying area, a storage area and a discharging end which are arranged in sequence, and the biological drying all-in-one machine works in the drying area; fresh sludge is fed into the feeding end of the biological drying tank and laid in the drying area through the biological drying all-in-one machine, the biological drying all-in-one machine adjusts the components and the water content of the fresh sludge, a biological agent is added, then materials are fully mixed, heat is generated through fermentation, the biological drying all-in-one machine adjusts environmental parameters by collecting real-time data, and the sludge is rapidly dried and dehydrated; sludge is dried by adopting long groove structure stacking and matching with mechanical turning and dynamic aeration ventilation functions of the biological drying all-in-one machine, and the biological drying all-in-one machine monitors environmental parameters in real time to adjust the working state, so that the sludge can be quickly dried and dewatered, the efficiency is improved, and the cost is reduced; the uniformity, stability and low water content of a product are ensured.

Description

technical field [0001] The invention relates to a biological drying system, which belongs to the technical field of sludge treatment. Background technique [0002] Recently, as an emerging drying technology, sludge biological drying technology has aroused interest in the industry; sludge biological drying technology uses the principle of microbial aerobic fermentation to induce heat production by microorganisms through forced ventilation to evaporate water. A technology; in recent years, biological drying technology has been widely used in the drying treatment of livestock and poultry manure and garbage dehydration and drying treatment, but the drying research applied to urban sludge is still rare in China; due to sludge biological drying Drying technology can effectively use the heat generated by microbial aerobic fermentation, and no external heat source is needed in the drying process, so it is a very energy-saving drying technology. [0003] The current biological dryin...
