Description
Technical Field
The invention relates to the technical field of environment-friendly equipment, in particular to integrated aerobic fermentation equipment and a fermentation process thereof.
Background
The harmless and recycling treatment of organic solid wastes is an important direction for the development of future environmental protection career in China, and the method for treating the organic solid wastes by utilizing automatic equipment and improving the automation degree, the intelligent degree and the treatment effect of the equipment is a main research and development field in the industry at present. The research and development work of the automatic aerobic fermentation equipment in the industry starts earlier, and some mature schemes are applied to the market. In the technical book, the "practical handbook for composting engineering" written in Li Ching and Peng Ping (ISBN 978-7-122-1217173-8); books such as "compost science and engineering" (ISBN 978-7-122-15562-7) by l.f. disaz, m.de betouldy, etc. have been variously described about reactor composting (i.e. equipment composting) at home and abroad, including silo-type composting reactors, tower-type composting reactors, drum-type composting reactors, stirred tank composting reactors, prototype stirred bed composting reactors, etc. A considerable part of equipment manufacturers in China carry out the market-oriented application of composting equipment, and a batch of relatively mature market solutions exist in roller fermentation equipment, silo type composting reactors and the like.
But the organic solid waste treatment still cannot rapidly meet the wide domestic market demand. The main body is as follows:
1. the existing equipment has no strong maneuverability, is a simplified version of composting facilities, has overlarge dead weight, and cannot be flexibly transported and deployed, which is the biggest defect in the existing equipment. A large part of the output of the organic solid waste in China comes from the dispersed organic solid waste treatment market, so the existing fermentation equipment is difficult to be applied to the dispersed organic solid waste treatment market.
2. The existing fermentation equipment in the industry is usually continuous production and has two main defects: one is that the fermentation process is not matched with the characteristics of aerobic fermentation, and the heating rates of the aerobic fermentation are not all the same due to different materials, temperatures, conditions and the like. For example, the technical schemes of application numbers CN201210060507.7 and CN201320138448.0 disclose continuous production equipment. The common defects of the devices are that in the low-temperature period in winter, when the temperature of the feeding material in the early stage is not raised, the feeding material in the front stage has to be turned over for feeding production, so that the difficulty of temperature accumulation is increased, and the problem of low efficiency of finished products after fermentation inevitably occurs in the later-stage fermentation process. Secondly, the stability of the equipment is difficult to guarantee, any link is broken down and the equipment is likely to be stopped and maintained, taking municipal sludge treatment as an example, the organic solid waste treatment has higher requirements on the non-continuity of the equipment, so the stability of the equipment is very important.
3. The material mixing is an important link in the aerobic fermentation process, and the most common mode in the industry is to mix by using a spiral mixer, namely, a plurality of material bins are used for feeding materials and the materials enter a continuous mixer for mixing. However, because the flow characteristics, the friction characteristics and the density of different materials are different, a plurality of factors which are difficult to control exist in the mixing mode, so that the mixing effect is not ideal, in order to solve the problem, some new solutions are proposed in the industry, for example, a method for mixing a plurality of materials in the same bin is proposed in the technical scheme with the application number of CN202010797888.1, although the defects existing in the traditional mixing mode are avoided in principle, the mixing equipment is too complex, and the situations of high cost, complex operation and the like can be caused.
4. However, most of the existing aerobic fermentation devices are difficult to sample and monitor the temperature, the water content of materials, the fermentation state and the like in the fermentation process, and the execution mechanisms of the measures of controlling the fermentation state, such as aeration, turning, deodorization, heating and the like, are not flexible, so that the equipment for the aerobic fermentation is blind and limp, the automation is difficult to realize, and the process automation adjustment of the organic solid waste aerobic fermentation through sensor feedback is difficult to realize.
5. Devices incorporating heating or heat recovery would help to improve the fermentation results. The full utilization of heat energy in materials and waste gas is an important means for reducing treatment cost and improving fermentation effect. There are some ways of sludge fermentation by heat energy recovery or electrical heating in the industry, such as the technical scheme disclosed in CN20162117161542.6, which adopts a means of heating gas to raise the temperature of the initial fermentation material. But still does not fully utilize the waste heat, and the cost cannot be further reduced.
6. The traditional aerobic fermentation mode mainly comprises in-situ static compost, shift dynamic compost and the like, no matter which composting mode is adopted, different advantageous floras exist in different stages of aerobic fermentation, the evolution of the floras requires time and conditions, and the advantageous floras cannot be intercepted by any traditional aerobic fermentation mode, so that the efficiency is low.
In order to solve the problems, an improved integrated aerobic fermentation device and a fermentation process thereof are designed.
