Description

Waste heat utilization dewatering system comprising horizontal aerobic fermentation reactor

Technical Field

The utility model relates to a waste heat utilization water removal system, concretely relates to waste heat utilization water removal system including horizontal good oxygen fermentation reactor.

Background

The main by-products produced by human life: organic wastes such as excrement, sludge and organic garbage are large in quantity and highly concentrated, and if the organic wastes cannot be effectively treated in time, environmental pollution is easily caused, and the environmental disaster is caused.

The 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 easily accepted by soil, secondly, pathogenic bacteria and parasitic ova in the wastes are basically killed by high-temperature fermentation in the composting process, the propagation of harmful bacteria is eliminated, meanwhile, the wastes are converted into organic fertilizers, the resource recovery is realized, the resource recycling requirement is met, and the virtuous cycle of natural substances 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 which integrates reduction, harmlessness and recycling into a whole.

At present, the common modes of aerobic fermentation mainly comprise site compost fermentation, vertical fermentation tank fermentation and horizontal roller fermentation reactor fermentation. The fermentation by using the horizontal aerobic fermentation reactor 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 determining the aerobic fermentation effect of the organic matters, the sealing is not good, not only can material leakage be caused, but also in the ventilation process of the system, a wind path is short-circuited from the sealing cover, odor overflows, so that insufficient oxygen supply is caused in the tank body, and waste gas and evaporated water vapor generated by fermentation cannot be effectively discharged; if the seal is too tight, the drive resistance is too high, and a large amount of energy is required.

At present, the horizontal aerobic fermentation reactor adopts two sealing modes, namely mechanical sealing and labyrinth sealing.

The mechanical sealing performance is relatively reliable, but the requirements on manufacturing and assembling precision are high, the manufacturing cost is relatively high, in order to ensure the sealing effect, the sealing material needs to be tightly attached to the fermentation cylinder, but the manufacturing precision of large-scale equipment is difficult to ensure, so that the friction resistance is large, and the driving energy consumption is high; because the frequent rotation of rotary drum, sealing material wearing and tearing are serious, need frequently to change, change untimely then can influence sealed effect, change in time then need shut down the maintenance, extravagant manpower and materials, still seriously influence the continuity of production.

The labyrinth seal has the advantages of simple structure and low manufacturing cost, but is limited by the precision of manufacturing and assembling, and in order to ensure the smooth operation of the fermentation cylinder, a larger gap needs to be arranged between the end part sealing cover and the fermentation cylinder, so that obvious material leakage and air leakage are easily generated, the material leakage needs to be cleaned and reflowed, a large amount of labor is consumed, and dirty and messy production sites are caused; the leakage of air can cause short circuit of oxygen supply and deodorization air paths and the overflow of odor, thereby causing insufficient oxygen supply inside the tank body, and the odor and the evaporated water vapor generated by fermentation can not be effectively discharged, thereby seriously affecting the fermentation effect; moreover, the labyrinth is easy to accumulate and clean, the material is easy to dry and block, the machine needs to be stopped for cleaning, and the production continuity is seriously influenced.

The main purpose of aerobic fermentation is to effectively realize the harmlessness and reduction of organic manure. According to the aerobic fermentation characteristic, the system has higher fermentation efficiency by maintaining the high temperature of the system, so that bacteria and pathogens can be killed more fully, the degradation of antibiotics in the excrement can be accelerated, and the harmlessness is more thorough; but the high temperature aerobic fermentation process can produce a large amount of high temperature and high humidity foul smell, outstanding reactor not only need collect the waste gas that produces in the fermentation process and innocent treatment, still need in time discharge the foul smell that contains a large amount of vapor through airing exhaust, introduce fresh oxygen for the fermented material simultaneously to promote the material and continuously high-efficient fermentation and take away the moisture in the fermented material, realize effectual minimizing.

At present, in order to maintain the high-temperature environment of high-temperature aerobic fermentation, the method mostly relies on external heating, such as hot water, heat conduction oil or hot air blowing and the like, the operation energy consumption is high, and the economical efficiency is poor; in order to achieve the moisture removal effect, a large amount of wet air in the fermentation tank needs to be pumped out, so that the treatment capacity of odor 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 by a large amount of pumped high-temperature wet air without recycling, so that a large amount of heat energy loss is caused, and the system operation cost is greatly increased; among the prior art, usually with the direct backward flow of damp and hot waste gas, but steam has been brought back to the reactor again, is absorbed by the fermentation material, and the moisture of material can not effectively be got rid of, can't accomplish effective minimizing of material, and because moisture does not taken away, the fermentation material moisture content in the fermentation cylinder is on the high side, and fermentation efficiency is low, and the fermentation effect is also poor.
