Description
Technical Field
The invention relates to the field of kitchen waste treatment, in particular to an energy-saving double-cavity kitchen waste treatment system.
Background
The kitchen waste has the characteristics of high moisture, organic matters, grease and salt content, easy decay, rich nutrient elements and the like. Due to the high water content, the kitchen waste cannot meet the requirement of heat productivity (not lower than 5000kJ/kg) of waste incineration, and is not suitable for direct landfill, and the incineration and the landfill cause a great amount of waste of organic matters. Meanwhile, as a large amount of kitchen waste enters a secondary market to form a great potential threat to human health except that a small part of the garbage such as pigs and hogwash oil derived from the kitchen waste is mixed into household waste for landfill, the treatment and disposal of the kitchen waste are more and more concerned by the whole society. Along with the process of urbanization, the quantity of kitchen waste generated is increased every year in China, and environmental problems and ecological problems caused by improper kitchen waste treatment are increasingly prominent.
The kitchen waste has high recycling value, the treatment technical route is diversified, and an important method is a microbial aerobic fermentation technology, namely, under an aerobic environment, the optimal environmental conditions of temperature and humidity are provided, and the organic substances in the kitchen waste are quickly decomposed by using the biological metabolic activity of heterotrophic aerobic microorganisms.
The complete aerobic fermentation is mainly divided into four stages: latent stage, heat generation stage, high temperature stage (45-65 ℃) and decomposition stage (<50 ℃), wherein the high temperature stage is the main process of decomposing organic compounds, and the decomposition stage is the indispensable process of decomposing products to achieve resource utilization.
The kitchen waste treatment equipment is mechanical equipment for decomposing kitchen waste by using an aerobic fermentation process.
Generally, kitchen waste treatment equipment rapidly decomposes a part of organic matters into carbon dioxide and water vapor under the action of microorganisms through means of heating, mechanical stirring, forced ventilation and the like, discharges the carbon dioxide and the water vapor through an air extractor, and dries the rest organic matters at high temperature to prepare the meat floss-shaped organic fertilizer.
However, most of the existing kitchen waste treatment equipment has two problems of high operation energy consumption and low decomposition degree of the treated products.
Most of the existing kitchen waste treatment equipment has the disadvantages of high-temperature heating and drying in the whole waste treatment process, huge extra energy consumption and high operating cost. In order to reduce energy consumption, heat preservation measures are usually adopted to reduce heat loss, or a heating mode is changed to reduce energy consumption, for example, water bath heating, electric heating plates, heat conducting oil and the like are adopted, but the actual energy-saving effect of the method is poor, and the energy consumption cannot be reduced to a greater extent. In addition, in order to reduce the fermentation period and discharge materials quickly, part of kitchen waste treatment equipment only completes the three stages before aerobic fermentation quickly in the fermentation process, and the decomposition stage is lacked, so that the decomposition degree of products is low.
