Problems solved by technology

However, the traditional aerobic fermentation has the following disadvantages: (1) The fermentation time is long, and more manpower management is required during the period; (2) The composting site, raw material storage and storage of composted products all need to occupy a considerable amount of land, and The land occupied by compost is directly proportional to the fermentation time; (3) Odor pollution, the sludge itself will emit odor before it is treated, and it will also emit odor and breed mosquitoes during the fermentation process; (4) Affected by climatic conditions, cold weather It lowers the temperature of the compost material and slows down the composting process. It can also cause other problems such as freezing of raw material equipment. The potential impact of rain and snow is more serious. Large rainfall increases the moisture content of the compost mixture, thus prolonging the composting time. composting time

Abstract

The invention discloses a heat recycling type sludge fermentation tower, and belongs to the technical field of sludge fermentation devices. The technical scheme key point is that according to the heat recycling type sludge fermentation tower, the inside of the tower body is divided into a tail gas collecting and waste heat insulating zone, a feeding and material preheating zone, a main fermenting zone, a cooling and assistant fermenting zone and a storing zone in sequence from top to bottom. The heat recycling type sludge fermentation tower is short in fermentation time, small in occupied area and good in fermentation effect, the moisture content of the sludge treated by the sludge fermentation tower is reduced, and transportation and follow-up resource recovery utilization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of sludge fermentation equipment, and in particular relates to a heat recovery type sludge fermentation tower. Background technique [0002] At present, the sludge treatment methods in my country mainly include direct landfill, incineration, thermal drying, anaerobic digestion and aerobic fermentation. Among them, the aerobic fermentation process has the characteristics of being economical and convenient, and the product can be recycled, and will gradually become an important method for sludge treatment in sewage plants. However, the traditional aerobic fermentation has the following disadvantages: (1) The fermentation time is long, and more manpower management is required during the period; (2) The composting site, raw material storage and storage of composted products all need to occupy a considerable amount of land, and The land occupied by compost is directly proportional to the fermentation time; (3) ...
