Description
Technical Field
The invention relates to aerobic fermentation equipment, in particular to a horizontal aerobic fermentation reactor and a waste heat utilization water removal system.
Background
The main by-products of human life: the organic wastes such as the excrement, the sludge and the organic garbage are large in quantity and highly concentrated, and if the organic wastes cannot be effectively disposed of in time, the organic wastes are extremely easy to cause environmental pollution and become an environmental disaster.
Organic wastes such as excrement, sludge and organic garbage are subjected to aerobic fermentation treatment, firstly, perishable organic matters in the organic wastes can be converted into organic nutrient soil which is easy to accept in soil, and secondly, pathogenic bacteria and parasitic ova in the garbage are basically killed by high-temperature fermentation in the composting process, so that the spread of harmful bacteria is eliminated, and meanwhile, the garbage is changed into organic fertilizer, so that the resource recovery is realized, the resource requirement is met, and the virtuous cycle of the substances in the nature is promoted. The method not only effectively solves the problem of reduction of the excrement, the sludge and the organic garbage, but also solves the problem of environmental pollution of the excrement, the sludge and the organic garbage.
Therefore, aerobic fermentation is a relatively ideal treatment method that integrates reduction, harmlessness, and recycling.
At present, the common modes of aerobic fermentation mainly comprise site composting fermentation, vertical fermentation tank fermentation and horizontal roller fermentation reactor fermentation. The horizontal aerobic fermentation reactor is utilized for fermentation, and has the remarkable advantages of high fermentation efficiency, high decomposition speed, short period, uniform material fermentation, good air permeability, small occupied area, low operation energy consumption and the like.
For the horizontal aerobic fermentation reactor, the sealing between the end sealing plate and the end of the fermentation cylinder is an important factor for determining the aerobic fermentation effect of the biological organic matters, and the sealing is poor, so that not only can the leakage be caused, but also the short circuit of an air path from the sealing cover and the overflow of odor are caused in the ventilation process of the system, thereby causing the insufficient oxygen supply in the tank and the ineffective discharge of waste gas and evaporated vapor generated by fermentation; if the seal is too tight, excessive driving resistance is caused, and a large amount of energy is required.
At present, the sealing mode adopted by the horizontal aerobic fermentation reactor mainly comprises two types of mechanical sealing and labyrinth sealing.
The mechanical sealing performance is relatively reliable, but the requirements on the manufacturing and assembling precision are high, the manufacturing cost is relatively high, the sealing material needs to be closely attached to the fermentation cylinder in order to ensure the sealing effect, but the manufacturing precision of large equipment is difficult to ensure, so that the friction resistance is high, and the driving energy consumption is high; because the rotating drum frequently rotates, the sealing material is seriously worn and needs to be frequently replaced, the sealing effect can be influenced if the sealing material is not timely replaced, the machine is required to be stopped for maintenance if the sealing material is timely replaced, the manpower and material resources are wasted, and the production continuity is seriously influenced.
The labyrinth seal has the advantages of simple structure and low manufacturing cost, but is limited by the precision of manufacturing, assembling and the like, and in order to ensure the smooth operation of the fermentation cylinder, a relatively large gap needs to be arranged between the end sealing cover and the fermentation cylinder, so that obvious material leakage and air leakage are easy to generate, the material leakage needs to be cleaned and reflowed, a large amount of labor is consumed, and the mess of a production site is caused; the air leakage can cause short circuit of the oxygen supply and deodorization air paths and can cause the odor to overflow, so that the oxygen supply in the tank body is insufficient, and the odor generated by fermentation and evaporated vapor can not be effectively discharged, thereby seriously affecting the fermentation effect; and the labyrinth is easy to accumulate materials, difficult to clean and easy to be blocked due to dry and knot of the materials, and the labyrinth needs to be shut down for cleaning, so that the production continuity is seriously affected.
The main purpose of the aerobic fermentation is to effectively realize harmless and reduction of organic manure. According to the aerobic fermentation characteristics, the high temperature of the system is maintained, so that the system has higher fermentation efficiency, bacteria and pathogens can be killed more fully, the degradation of antibiotics in the excrement can be accelerated, and the harmless treatment is more thorough; but the high-temperature aerobic fermentation process can generate a large amount of high-temperature and high-humidity odor, the excellent reactor not only needs to collect and harmlessly treat the waste gas generated in the fermentation process, but also needs to timely discharge the odor containing a large amount of water vapor through exhaust air, and simultaneously introduces fresh oxygen into the fermentation material, thereby promoting continuous and efficient fermentation of the material and taking away the moisture in the fermentation material, and realizing effective reduction.
At present, in order to maintain a high-temperature environment of high-temperature aerobic fermentation, the method is mostly based on exogenous heating, such as hot water, heat conducting oil or hot blast blowing, and the like, so that the operation energy consumption is high and the economical efficiency is poor; in order to achieve the effect of removing moisture, a large amount of wet air in the fermentation tank needs to be pumped out, so that the odor treatment capacity is large, and the collection and treatment cost is high; in the high-temperature aerobic fermentation process, heat generated by fermentation can be taken away in a large amount by the pumped high-temperature wet air without recycling, so that a large amount of heat energy is lost, and the running cost of the system is greatly increased; in the prior art, wet and hot waste gas is directly refluxed, but water vapor is brought back to the reactor and is absorbed by fermentation materials, the water of the materials cannot be effectively removed, the effective reduction of the materials cannot be realized, and the water content of the fermentation materials in the cylinder body of the fermentation tank is higher because the water is not taken away, the fermentation efficiency is low, and the fermentation effect is also poor.
