Description
Technical field
The composting technology field that the present invention relates to lignin-sludge, animal waste, municipal wastes, kitchen waste, garden waste etc. is a kind of ventilation plant that is applied to composting process specifically.
Background technology
Composting is under controlled condition, utilizes the effect of microorganism and enzymic activity to accelerate organic Biodegradation and biotransformation, finally makes organism reach the process of becoming thoroughly decomposed and stabilization.Composting process not only can reduce volume, weight, the stink of organic solid castoff, kills pathogenic bacteria, worm's ovum, plant seed etc., can produce a large amount of soil ulmin simultaneously.The composting production of producing, can be used as soil conditioner and plant nutrition source, can effectively improve Soil structure, increase soil fertility.At present, composting technology has been widely used in processing excess sludge, animal waste, municipal wastes, kitchen waste, garden waste etc.The parameter that affects composting process is a lot, and the significant parameter that affects composting material has: C/N ratio, pH value, water ratio, granularity, organic content, C/P compare etc., and main control parameters in composting process has: temperature, oxygen level etc.Ventilation can be used to control temperature and the oxygen level of composting process, so, ventilate and be considered to most important factor in compositing system.Reasonably ventilation not only can improve composting production quality, and can save energy consumption, otherwise, too high rate of venting not only causes ventilation loss excessive, is unfavorable for maintaining heap temperature, and can cause a large amount of nitrogens loss, lower the fertilizer efficiency of composting production, increase compost energy consumption; But too low rate of venting, will reduce the oxygen concn of heap in body, and then cause heap body part to detest (lacking) oxygen, thereby produce a large amount of foul smell and NxO, methane isothermal chamber gas, bring serious pollution and harm to surrounding enviroment.Obviously, the optimization of compost Design of Ventilation System, operation and management not only contributes to wideling popularize of composting technology and widespread use, and contributes to reduction of greenhouse gas discharge.Composting process ventilates and plays the effect of oxygen supply, removal moisture and heat radiation.
In sum, select suitable compost draft type, need to consider following principal element: the aspects such as condition of technology and economy, utilization of materials, transportation and process cost, maintenance of the equipment and management, staff straining, place.At present, China rural area is because the condition such as economy, technology falls behind, and composting agricultural wastes mostly adopt the mode of natural ventilation and turning; The composting of city organic solid castoff is the modes that adopt forced ventilation fermentation cabin more.Therefore,, according to China's national situation, can select the passive draft type that facility investment is few, manual operation expense is few with composting agricultural wastes; Consider floor space and compost cycle, organic garbage of city compost selects forced ventilation In-vessel composting system comparatively applicable.
At present, existing compost draft type can be divided into: natural ventilation, turning, passive ventilation, forced ventilation etc., and natural ventilation, turning, passive draft type are usually used in Windows composting system, forced ventilation mode is usually used in forced ventilation static buttress and most of In-vessel composting system, natural ventilation is mainly the diffusion phenomena that rely on air, by accumulation horizon surface, oxygen is spread, is sent to heap body inside, passive draft type is to utilize the perforated pipe being arranged in heap body, promote the transmission of air in windrow, its principle is the temperature head due to heap inside and outside, because rising, the inner hot gas of heap body make extraneous air be inhaled into heap body, passive ventilation does not need turning and forced ventilation, so greatly reduce investment and working cost, forced ventilation utilizes blower fan to carry out malleation air blast to material exactly, the mode of negative pressure ventilation and both combinations, carry out gaseous interchange, promote mass transfer and the oxygen transmission to microorganism, but, forced ventilation (malleation air blast or negative pressure ventilation) can cause temperature in composting process, the skewness such as water ratio, for example, for malleation forced ventilation, ventilator trunk near zone has obvious cooling effect, be difficult to make the windrow in this region to reach sterilization effect, because making to pile body bottom, passing into of dry air become dry, contrary heap body upper strata is but because saturated air cooling forms a large amount of water of condensation, can affect compost effect.
Existing " transverse tube type
*" ventilation plant: refer to be embedded in the vent-pipe system that is " king " font of compost bottom, the ventilation hole that distributes on each take-off pipe, exists energy consumption large; required pressure is large, and the inner oxygenation of compost is inhomogeneous, and the time of becoming thoroughly decomposed is long; influenced by ambient temperature large, is not suitable for the shortcomings such as compost in winter.
Summary of the invention
In sum, the object of the present invention is to provide a kind of ventilation plant that is applied to composting process.
The object of the invention is to realize by following technology:
Be applied to a ventilation plant for composting process, formed by hollow circular-tube I and hollow circular-tube II, hollow circular-tube I and the socket of hollow circular-tube II; 3/7 place of 1/5 place, hollow circular-tube I lower end and hollow circular-tube II lower end is provided with closed circle; Closed circle, by the space partition between hollow circular-tube I and hollow circular-tube II, is divided into overdraught space and leg space ventilation space; The both ends open of hollow circular-tube I; The tube wall of hollow circular-tube II is provided with ventilating pit; The exposed junction of hollow circular-tube I connects external equipment; The lower end of hollow circular-tube II is coniform.
Advantage of the present invention and beneficial effect:
1, composting process ventilation system involved in the present invention possesses natural ventilation, forced ventilation and passive ventilation function simultaneously, can generally be applicable to the compost treatment of the solid waste in China rural area and city.
2, the present invention is easy to use, and efficiency is fast, and the riding position in compost can be adjusted voluntarily, controls Uniform Ventilation, and is not easy to stop up, safe and reliable, enhances productivity, and saves the working hour.

As shown in Figure 6, by ventilation plant a hollow circular-tube I 1 upper end mouth of pipe access vacuum fan, ventilation plant b hollow circular-tube I 1 upper end open is in air, part ambient atmos enters ventilation plant b by ventilation plant b hollow circular-tube, pass through again compost material, enter the leg space ventilation space at ventilation plant a3/7 place, enter in outside air by the hollow circular-tube I 1 of ventilation plant a; Another part ambient atmos enters the overdraught space at ventilation plant a4/7 place by hollow circular-tube II 2 upper end open of ventilation plant a, then the compost material of flowing through downwards, enter the leg space ventilation space at ventilation plant 3/7 place by ventilation plant a hollow circular-tube II 2 ventilating pits, then enter vacuum fan by ventilation plant a hollow circular-tube I 1 and discharge.
As shown in Figure 7, the ventilation plant a hollow circular-tube I 1 upper end mouth of pipe is accessed respectively to a blower, hollow circular-tube I 1 upper end open of ventilation plant b accesses respectively a vacuum fan, gas blower is blasted air-flow the leg space ventilation space at ventilation plant a3/7 place by the hollow circular-tube I 1 of ventilation plant a, then airflow passes compost material directly enters the leg space ventilation space at ventilation plant b3/7 place, via the hollow circular-tube I 1 of ventilation plant b, discharge by vacuum fan.
Compost in above embodiment, according to ingredients by weight ratio: wheat husk, mud, recycled sludge compost=1:1:1; Initial aqueous rate is 55%; Initial C/N=30:1.
Table 1: be the forced ventilation contrast table of existing transverse tube type ventilation plant and embodiment 3,4,5,6
