Solar energy evaporation device and solar energy evaporation method for kitchen waste water

Abstract

The invention discloses a solar energy evaporation device and a solar energy evaporation method for kitchen waste water. The device includes a solar energy heat collector, a thermal energy conversion device, an air pump, a main air pipe, a plurality of branched air pipes, an aeration pipe and a pond. The solar energy heat collector, the thermal energy conversion device and the air pump are connected to each other successively. An air outlet of the air pump is connected to the main air pipe. The branched air pipes are connected to the main air pipe. The branched air pipes are stretched to the bottom of the pond. The aeration pipe is connected to the ends of the branched air pipes. In the device, air is heated through solar energy, and then hot air is introduced to the bottom of the kitchen waste water through the air pump and the aeration pipe, wherein water vapor is brought out during an air exhaustion process, thereby achieving waste water reduction. The device is simple in operation, achieves automatic control and is free of manual management.

Description

Technical field: [0001] The invention belongs to the field of kitchen waste treatment, and in particular relates to a solar evaporation device and an evaporation method for kitchen sewage. Background technique: [0002] The food waste collected and transported usually has a high moisture content. Simple solid-liquid separation methods can be used to collect and reuse food waste water. In order to further improve the utilization rate, the water content can be appropriately reduced to increase the organic matter content. Concentration, but on the one hand, sewage often contains a certain amount of oil and light organic impurities, which float on the surface to prevent the evaporation process; on the other hand, it is often accompanied by high energy consumption, so it is necessary to design an economical and practical kitchen sewage concentration device. Invention content: [0003] The purpose of the present invention is to provide a low-cost, economical and practical solar ...
