Problems solved by technology

[0003] At present, the main heating methods used are thermal aeration and heat conduction. The heating rate of heat conduction is slow to respond, and it is difficult to directly transfer the temperature to the central point. The energy consumption is high, and the thermal insulation performance is poor, which greatly increases the heat dissipation; thermal aeration uses hot air. Through the biomass pile, direct contact with heat supply, the moment the hot air contacts with the biomass material, the surface water vapor will be evaporated, directly reducing the temperature of the biomass material, so that most of the heat will be taken out of the system, so that the entire reaction temperature cannot reach the expected temperature , affecting the experimental results

Abstract

The invention discloses a low-temperature infrared radiation coupling biological reaction method and device. The method comprises the following steps: performing natural stacking on biomass material or placing in a stirring device, performing turning or mechanical stirring on the biomass material at fixed time, and performing continuous irradiation on the biomass material through an infrared irradiation device, and providing stable and appropriate environment temperature for microorganism aerobic fermentation heat production in the biomass. The microorganism aerobic reaction is performed on the traditional biomass, and then the coupling with the infrared radiation is performed, the heat transfer is changed as the non-contact heat transfer from the contact heat transfer, the heat aeration for maintaining the material temperature through heat convection transfer is changed as heat radiation, the problems that large amounts of water vapor is transiently taken away from the biomass surfacesince the heat air rapidly passes through the biomass surface in the heat aeration, and the actual material temperature cannot achieve the expected temperature since the heat is absorbed through water evaporation are greatly improved; and the whole microorganism reaction process is optimized, the microorganism reaction activity is greatly improved, the reaction period is further shortened, and the reaction efficiency is improved.

Background technique [0002] Aerobic biological treatment refers to the use of aerobic microorganisms (including facultative microorganisms) to carry out biological metabolism in the presence of oxygen to degrade organic matter and make it stable and harmless. Microorganisms use the existing organic pollutants as substrates for aerobic metabolism, release energy step by step through a series of biochemical reactions, and finally stabilize with low-energy inorganic substances to meet the requirements of harmlessness, so as to return to the natural environment or further deal with. [0003] At present, the main heating methods are thermal aeration and heat conduction. The heating rate of heat conduction is slow to respond, and it is difficult to directly transfer the temperat...
