Description
Technical field
The utility model relates to aerobic compost process solid waste field, particularly aerobic compost ventilation plant.
Background technology
Aerobic compost is a kind of solid waste method of disposal grown up the eighties of last century middle and later periods.Current, the municipal wastes of China, aquaculture ight soil and waste plant mud all face process predicament to a certain degree.Traditional landfill method needs land occupation, and its processing power can not infinitely promote, and the leachate contamination environment that landfill produces.And aerobic compost technology can utilize in high temperature microbe under aerobic conditions, solid waste is innoxious, stabilization, minimizing; Finally use also field with fertilizer form, turn waste into wealth.Therefore the research of aerobic compost technology is significant for the solidification disposal of waste of China.
Traditional composting technology based on static turning method, the method usually in proper order/frequency of 2-3 days carries out turning mixing to heap body, to play the effect regulating temperature and supplemental oxygen.But manual operation load needed for this method is large, a large amount of odor pollution environment of frequent turning dissipation; And turning the temperature of scattering and disappearing uncontrollable with the oxygen supplemented, make the fermented quality piling body be difficult to ensure.
Development in recent years has gone out static aeration technology to regulate temperature and the supplemental oxygen of compost, and the controllability of the method to heap body and parameter has had raising.Aeration technology at present most main flow be time intermittent ventilation technology; But compost is the process of a change at the oxygen consumption rate of temperature raising period, traditional intermittent ventilation is for the heap temperature-oxygen balance of body self or reasonable all not in energy consumption.Due to the change of temperature, easily occur overdraft or deficiency in draught, to cause or oxygen supply is sufficient but temperature declines too fast, or temperature maintains but for the situation of hypoxgia.Also the technology adopting temperature feedback control to ventilate is had to occur, the method ensure that compared with time intermittent ventilation method the temperature of piling body controls, but can not ensure that heap body is to the demand of oxygen mark, easily there is the situation of locality, interim anaerobism, make heap body internal-response insufficient, fermented quality is affected.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of aerobic compost ventilation plant, improves the precision that aerobic compost ventilation controls.
For solving the problem, the technical solution adopted in the utility model is: aerobic compost ventilation plant, comprises controller, frequency transformer, frequency conversion fan, signal transmitting device, and is located at temp probe, moisture probe, the dissolved oxygen probe in fermentor tank; Described temp probe, moisture probe, dissolved oxygen probe are connected with controller by signal transmitting device; Described controller is connected with frequency transformer, and described frequency transformer is connected with frequency conversion fan.
Further, described controller is PLC.
Further, described PLC comprises control panel, manual/auto switch.
Further, described control panel is touch-screen.
The beneficial effects of the utility model are: detect data in fermentor tank in real time by temp probe, moisture probe, dissolved oxygen probe, and by the data that detect through PLC treatment and analysis, PLC controls frequency transformer in real time according to result, the opening and closing of final control frequency conversion fan and discharge quantity of fan, realize the accurate conveying of the aerobic temperature raising period ventilation of heap body, prevent deficiency in draught, excessive situation of ventilating, drafting efficiency is high, and energy utilization rate is high; Ensure that heap body is to the demand for control of temperature and oxygen mark, heap precursor reactant is abundant, quality of finished product good simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises controller, frequency transformer, frequency conversion fan, signal transmitting device, temp probe, moisture probe, dissolved oxygen probe; Wherein, temp probe, moisture probe, dissolved oxygen probe are arranged in fermentor tank, and are connected with controller by signal transmitting device; Controller is connected with frequency conversion fan by frequency transformer.
Above-mentioned, temp probe, moisture probe, dissolved oxygen probe are respectively used to detect the temperature of compost heap body in fermentor tank, humidity and oxygen mark, and detection data are sent to signal transmitting device; Signal transmitting device is used for the simulating signal aforementioned detection data transformations being become 4-20mA, is input in controller; Controller is used for carrying out treatment and analysis to the simulating signal of input, transmits control signal to frequency transformer; Frequency transformer is used for the control according to control signal, frequency conversion fan being carried out to opening and closing and discharge quantity of fan.
During application, controller in the utility model preferably PLC, user can input temp-oxygen mark bivariate function program in the controller, and the humiture utilizing temp probe, moisture probe, dissolved oxygen probe to collect and oxygen mark, realize Frequency Converter Control.Controller comprises control panel, manual/auto switch.Described control panel, as man machine operation interface, can be touch-screen, and face can set each parameter boundary of function independently, easily on the touchscreen; Described manual/auto switch, automatic transmission is binary function and controls, and manual is time intermittent ventilation control; After compost temperature raising period terminates, enter latter stage of ripening, oxygen mark, the temperature of heap body almost no longer change; Now because mummification material needs stable ventilation, can switch to manual, control air quantity with the timed interval of presetting in program and blower fan frequency.
In the utility model, frequency transformer is the conversion bridge connecting controller and frequency conversion fan.After controller output frequency value, outputting to blower fan by frequency transformer, by specifying the frequency of fan operation, controlling the rotating speed of fan operation, reach the object controlling air quantity.Therefore, it is possible to effectively overcome the problem in the control of aerobic compost ventilation.
Compared with prior art, the advantage of this device is: the frequency conversion fan using speed variable, opening and closing and the discharge quantity of fan of blower fan is controlled with temperature-oxygen mark bivariate function program, realize the accurate conveying of the aerobic temperature raising period ventilation of heap body, prevent deficiency in draught, ventilate excessive situation, drafting efficiency is high, and energy utilization rate is high; Ensure that heap body is to the demand for control of temperature and oxygen mark, heap precursor reactant is abundant, quality of finished product good simultaneously; Simple to operate, system cloud gray model is controlled by pre-set programs, and information record is automatically completed by logging software and exports in real time with curve, and monitoring is convenient, and Personnel Dependence degree is extremely low, maximizes and reduces cost of labor.In addition this central control system independently can arrange the non-interfering program of many groups, and to connecting, many cover fermentor tanks run simultaneously, and it is convenient especially that the compost heap body for different qualities compares, the compost fermentation condition of not clear characteristic is groped.
