Kitchen waste aerobic fermentation equipment with capability of rapid drying

Abstract

The invention provides kitchen waste aerobic fermentation equipment with the capability of rapid drying. The kitchen waste aerobic fermentation equipment comprises a reaction cavity with the function of mixing, a cooling water circulation and condensate water collection system, an air heating and ventilation system with the function of deodorization, a water bath heating and thermal insulation system and an intelligent control system with the function of remote monitoring, wherein a temperature / humidity sensor and an oxygen concentration sensor are installed in the reaction cavity and used for monitoring the temperature, the humidity and the oxygen concentration in the reaction cavity; a heater and a temperature sensor are installed in a water bath cavity and can be used for providing heat to the reaction cavity timely, a thermal insulation interlayer is arranged outside the water bath cavity and used for preserving the heat of the water bath cavity; the air heating and ventilation system can be used for ensuring the oxygen concentration in the reaction cavity in the treating process; the cooling water circulation and condensate water collection system can be used for educing water vapor in the reaction cavity timely; a tail gas deodorization system can be used for preventing secondary environmental pollution due to the gas; and the equipment is controlled to run by a PLC (Programmable Logic Controller) intelligent control system. The kitchen waste aerobic fermentation equipment has a simple structure, is low in the running energy consumption and is good in the treating efficiency.

Description

technical field [0001] The invention belongs to the field of organic solid waste treatment and resource recovery technology, and is especially suitable for the treatment and disposal of organic waste such as kitchen waste. Background technique [0002] Food waste mainly comes from food processing leftovers (kitchen waste) and food residues (swill) produced in the catering service industry, households, canteens of enterprises and institutions, etc. With the rapid development of our country's economy and the gradual acceleration of urbanization, the output of kitchen waste has increased significantly nationwide. In large and super-large cities such as Beijing, Shanghai, Shenzhen, etc., the output of kitchen waste The daily output has reached thousands of tons, and the annual output of food waste in the country has reached 10 million tons. With the continuous advancement of urbanization, more and more attention has been paid to food safety and environmental safety, and the tra...

AI Technical Summary

Problems solved by technology

At present, the treatment technologies of food waste mainly include landfill, incineration, feed treatment, anaerobic fermentation and aerobic composting, etc. Among them, anaerobic fermentation and aerobic composting have more potential, but the treatment cycle of these two methods is relatively long , it is difficult to meet the daily production and clearance requirements of food waste
