Background technology
That composting is that organic solid castoff is realized is innoxious, the effective way of minimizing and resource utilization.How to accelerate material and decompose, the composting process reduces processing cost ahead of time, is that composting is applied to the key subjects that environmental improvement and production high-quality fertilizer need to be resolved hurrily and reduce nutrient loss etc.Aerobic fermentation is the main means of present compost fermentation.Aerobic fermentation is to make good use of the quick degraded that oxygen animalcule carries out organic matter under good oxygen condition, and therefore, the ventilation oxygen supply is the important factor that guarantees that aerobic fermentation carries out smoothly.Ventilation can be supplied with the required oxygen of mikrobe metabolism, takes away part moisture, can adjust the control heap temperature simultaneously.Yet because temperature is in continuous variation in whole fermentation process, and along with variation of temperature, microbe groups also is among the ongoing dynamic change, and the oxygen requirement of microbe groups also changes thereupon like this.If hypoventilation will suppress the activity of aerobic microbiological, make fermentation period elongated, influence the quality of biological organic fertilizer.If it is too prosperous to ventilate, microbial activities is vigorous, the organic matter decomposition aggravation, and the soil ulmin accumulation reduces, and ventilation is too vigorous simultaneously also can take away great amount of heat, influences leavening temperature.
Present aerobic fermentation plenum mainly is the MC mode, or moves with (blower fan) of timer control blower fan, or through the monitoring to temperature, the control ventilation.These modes can't satisfy different microorganisms population, the different steps demand to oxygen, are difficult to accomplish that an amount of of production process air flow supplies with in good time, can't guarantee the optimized operation of fermenting process.
The utility model content
The purpose of the utility model provide a kind of simple in structure, cost is low, can ventilate to composting fermentation process, realizes the ventilation intelligence control system that is used for the compost aerobic fermentation of intelligent control.
A kind of ventilation intelligence control system that is used for the compost aerobic fermentation; Its special feature is: comprise being inserted in intravital at least 1 oxygen sensor of compost, at least 1 TP and at least 1 moisture transducer; All the sensors all is connected with computer-electrical through data acquisition module, thereby and computingmachine is electrically connected the control fan starting through unit or stops with blower fan.
Wherein computingmachine adopts the IPC that has man-machine interface, and unit adopts PLC.
The system of the utility model is specially in the compost aerobic fermentation process; Can't realize that an amount of defective of in good time supplying with of ventilation proposes; Be intended to according to microbial population in the different fermentations growth characteristics in period; But utilize air demand in the mathematical model science control composting fermentation process, the optimization production process.This system is simple in structure, cost is low, can carry out the whole control of intellectuality, unmanned operation to single compost fermentation storehouse and a plurality of colonies formula fermentation cabin, improves compost fermentation efficient, improves the organic fertilizer product quality.Thereby be the rational and efficient use of agricultural wastes, condition has been created in the production operation that becomes more meticulous of compost fermentation.The system of the utility model can be according to the composition of composting material; The population of mikrobe is realized an amount of air feed in good time through ordering parameter, realizes optimized operation; Also can be through the adjustment of parameter, the minimizing that is applied to sludge fermentation system and municipal solid wastes is handled.

Accompanying drawing 2 is the logic theory block diagram of the utility model;
Accompanying drawing 3 is the MC schema of the utility model.
Embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises and is inserted in intravital 1 oxygen sensor of compost, 1 TP and 1 moisture transducer.The quantity of transmitter and probe institute slot are put can be according to the width of heap body in the fermentation cabin, highly, the air inlet position, measure adjustment voluntarily such as precision.Also comprise the data acquisition module that is connected with all the sensors; This data acquisition module is connected with computer-electrical; Computingmachine specifically can adopt the IPC that has man-machine interface, thereby computingmachine is electrically connected according to the startup of the information that collects and pre-set programs control blower fan through the PLC unit and stops with blower fan.
The system of the utility model is made up of one or more oxygen sensors, TP, moisture transducer, data acquisition module, computingmachine and s operation control software, logic circuitry, unit, topworks's parts such as (blower fans).Can be according to the growth characteristics of different fermentations dominant microflora in period, the growth oxygen requirement is confirmed key parameter span of control such as heap temperature, moisture, through operation, the start-stop time of intellectuality control blower fan, the adjustment oxygen-supplying amount satisfies the thalli growth demand.Can adopt existing conventional compost aerobic fermentation technology as for concrete key parameter.Native system has been realized the robotization mode, and is different with the monitoring temperature feedback control system of routine, formed temperature-oxygen feedback control system, and through the monitoring oxygen concentration, conversion oxygen concn rate of change through model assessment, sends wave then.
Embodiment 1:
1, gas blower or vacuum fan are connected with ventilator trunk, draft type adopts fertile stack temperature-oxygen feedback assembly to regulate automatically in the yeast phase.With monitoring oxygen concentration and temperature is main, carries out the start and stop control of blower fan.In yeast phase; According to the oxygen requirement of intensification, high temperature, temperature-fall period, (through the rate of change of monitoring gas oxygen concentration, i.e. gas oxygen concentration velocity slope; Its value has reflected the microorganism growth speed) fan starting of adjustment control in time stand-by time fragment, satisfy the oxygen supply demand.The control leavening temperature is not higher than 70 ℃.
