A bio-drying reactor that prevents backflow of condensed water

Abstract

The invention discloses a bio-drying reactor capable of preventing condensate water from refluxing. The bio-drying reactor comprises a reactor body and a support plate, wherein an air inlet connected with a blast blower is formed in the bottom of the reactor body; a plurality of thermometers are arranged at different heights inside the reactor body; a corresponding sampling opening is formed in the lateral wall of the reactor body at the height equal to each thermometer; a conical head cover is arranged above the reactor body; the conical head cover comprises a main body part of the conical head cover, an air outlet formed in the top of the conical head cover, and an annular flume arranged at the bottom; the main body part of the conical head cover inclines 45 degrees; the inner diameter of the annular flume is consistent with the outer diameter of the reactor body; the support plate is arranged on the outer edge of the upper part of the reactor body; a turnover stirring apparatus is arranged inside the reactor body, and is driven by a motor by virtue of a belt. Compared with the prior art, the condensate water can be prevented from falling back to the reactor, resulting in rise of the moisture content of the sludge, and the bio-drying reactor can play a good heat preservation effect.

Description

technical field [0001] The invention relates to a biological drying reactor, in particular to a biological drying reactor equipped with a device for preventing condensed water from flowing back. Background technique [0002] Sludge biological drying reaction is a relatively fast drying process that uses microorganisms to decompose organic matter in sludge to generate heat, and evaporate water through ventilation. Biological drying can reduce the moisture content of sludge to less than 50% in a short period of time. It is an environmentally friendly, energy-saving and efficient biological drying method. During the bio-drying reaction, the ventilation will take the saturated water vapor in the reactor out of the pile, but when the water vapor contacts the top cover, it will condense into water droplets on the top cover due to the temperature drop, and drop to the bottom of the reactor. In terms of materials, the moisture content of the materials increases; at the same time, i...

Problems solved by technology

During the bio-drying reaction, the ventilation will take the saturated water vapor in the reactor out of the pile, but when the water vapor contacts the top cover, it will condense into water droplets on the top cover due to the temperature drop, and drip into the reactor. In terms of materials, the moisture content of the materials increases; at the same time, in the process of biological drying, it is necessary to turn the piles to promote ventilation and oxygen supply, high porosity and uniform materials, etc., but the traditional method often uses manual turning, which is time-consuming and labor-intensive.
