Abstract
A septic tank safety inspection shaft control system comprises a gas concentration sensor, a gas pressure sensor, a micro processing control unit, a relay and an exhaust valve. The gas concentration sensor and the gas pressure sensor are connected with the micro processing control unit in parallel, the relay is connected with the micro processing control unit in series, and the exhaust valve is connected with the relay in series. According to the septic tank safety inspection shaft control system, the working principle is that the gas concentration sensor and the gas pressure sensor are utilized to detect the concentration and pressure of harmful gases such as biogas in a septic tank, a sensing signal is output, data analysis processing is conducted on the sensing signal through the micro processing control unit, and comparison with a set value is conducted. When the sensing signal is larger than the set safety value, the micro processing control unit sends out a control signal to drive the relay to act, a power supply is powered on, and the exhaust valve is made to act, automatic exhausting is conducted till the pressure or concentration of the gas is reduced or lowered to the set safety value, potential safety hazards of the septic tank are eliminated, and the surrounding public environment and public personal safety are guaranteed.
Description
Technical field
The invention belongs to municipal and environment-friendly infrastructure field, particularly relate to a kind of septic tank manhole control system.
Background technology
In existing municipal and environment-friendly infrastructure, septic tank is as the requisite basic environmental protection facility in city, and its enormous amount, application places is broad, is extremely important municipal and environment-friendly facility.Along with the progress of urbanization and the aggravation of environment pollution, septic tank serves positive role to protection water body.Now, in the large small city of China, septic tank is one of basic measures becoming environmental protection, are basic sludge treatment facilities, are also the pretreatment facilities of sanitary sewage simultaneously.
Septic tank is a kind of principle utilizing precipitation and anaerobic fermentation, removes the organic treatment facility of suspension in sanitary sewage, belongs to elementary transitionality life process structure.Owing to containing a large amount of sanitary sewage dirts in septic tank, fuel gas and the toxic and harmfuls such as a large amount of formaldehyde, ammonia, nitrogen, carbon dioxide, carbon monoxide, hydrogen sulfide can be produced in the process of anaerobic fermentation, therefore septic tank belongs to the hazardous area having risk of explosion, and concerning the construction operation personnel being engaged in septic tank cleaning, construction or the operations such as maintenance, then have and the poisoning high risk of biogas occurs.Therefore, how to reduce or alleviate the possibility of septic tank blow-up or intoxication accident, taking precautions against or eliminate accident risk, is the problem that those skilled in the art face.
Summary of the invention
For above-mentioned existing problems; the present invention proposes a kind of septic tank manhole control system; can the pressure of the toxic and harmful such as biogas or concentration in automatic detection septic tank; and automatically take corresponding safeguard measure; reduce or reduce pressure or the concentration of pernicious gas; guarantee surrounding enviroment and public's personal safety, to solve the deficiencies in the prior art.
The technical solution used in the present invention is:
A kind of septic tank manhole control system, comprise gas concentration sensor, gas pressure sensor, micro-processing and control element (PCE), relay and outlet valve, described gas concentration sensor and gas pressure sensor and micro-processing and control element (PCE) are connected in parallel, described relay and micro-processing and control element (PCE) are connected in series, and described outlet valve and relay are connected in series.
Operating principle of the present invention is the concentration and the pressure that utilize gas concentration sensor, gas pressure sensor to detect the pernicious gases such as biogas in septic tank, and export induced signal, by micro-processing and control element (PCE), Data Analysis Services is carried out to induced signal, and compare with setting value.When sensor output induced signal is greater than setting safety value, micro-processing and control element (PCE) sends control signal and drives the actuating of relay, relay switches on power and makes outlet valve action, carries out automatic vent, until the pressure of pernicious gas or concentration reduce or is reduced to setting safety value.
Beneficial effect of the present invention is: when the concentration of gas in septic tank or pressure meet or exceed after setting safety value, outlet valve can be controlled by micro-processing and control element (PCE) to be automatically exhausted, thus reduce or reduce pressure or the concentration of pernicious gas, within making the pressure of the pernicious gases such as the biogas in septic tank or concentration automatically maintain setting safety value, thus eliminate septic tank potential safety hazard, guarantee periphery PE and public's personal safety.
Accompanying drawing explanation
Fig. 1 is control principle block diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
A kind of septic tank manhole control system, see accompanying drawing 1, comprises gas concentration sensor, gas pressure sensor, micro-processing and control element (PCE), relay and outlet valve.Wherein, gas concentration sensor and gas pressure sensor and micro-processing and control element (PCE) are connected in parallel, and described relay and micro-processing and control element (PCE) are connected in series, and described outlet valve and relay are connected in series.
Further, gas concentration sensor, gas pressure sensor and outlet valve can be arranged on well lid, and are arranged in septic tank manhole by the probe of gas concentration sensor and gas pressure sensor.
Reliable for guaranteeing automatic ventilating function, outlet valve can adopt motor operated valve, to carry out analogue enlargement adjustment, specifically can adopt with automatically and the electrical ball valve of manual adjustments degassing function or electric butterfly valve, manually carries out adjustment be vented so that convenient where necessary.
Further, be protection sensor probe, netted protective cover can be set outside the probe of gas concentration sensor and gas pressure sensor.
The foregoing is only better embodiment of the present invention, not in order to limit type of the present invention.All any amendments, change etc. done on basis of the present invention, all belong to protection scope of the present invention.
