Description
One, technical field
The invention belongs to technical field of waste gas treatment, be specifically related to a kind of spraying semi-dry desulphurization facility monitor terminal.
Two, background technology
The a lot of urban air SO of China
2, H
2s is seriously polluted.For the sulfur-containing compound of industrial enterprise's discharge, the main desulfurization equipment that adopts carries out desulfurization, rear discharge up to standard, to reduce the discharge capacity of sulfide.Wherein, semi-dry desulphurization technology is domestic and international the most widely used desulfurization treatment process owing to investing little, Limestone-gypsum Wet Flue Gas Desulfurization Process technique.The method main technique utilizes the strength of machinery or air-flow absorbent to be dispersed into superfine little misty liquid droplets, misty liquid droplets forms larger contact surface area with flue gas, the sulfur method of a kind of exchange heat occurred between gas-liquid two-phase, quality transmission and chemical reaction.
But because environmental consciousness is thin, although country has multiple enviromental protection law, regulation and regulation to retrain, a lot of desulfurization treatment facility is still and runs under the supervision of government's environmental protection and relevant departments.Still have much such enterprise, its desulfurization treatment facility is opened often daytime, close in the evening, or open when checking, do not open when not checking, government's environmental protection and interested regulatory authorities are then beyond one's ability to help to the supervision of its desulfurization equipment or supervision.To compare big-and-middle-sized power plant, cement plant, Coal Chemical Industry and smelter etc., because treatment scale is large, pollutant generation is many, these facilities generally have online equipment, government and interested regulatory authorities can obtain relevant Real-time process service data by online facility, thus monitor its operating condition, treatment efficiency and qualified discharge situation in real time.These on-line monitoring equipment mostly expensive, operating cost is high and need dedicated technician to carry out management maintenance.Flue gas desulfurization facilities as online in a set of routine then needs 60-80 ten thousand yuan, even more expensive, and general medium-sized and small enterprises are difficult to bear.Although semi-dry desulphurization treatment facility is small, if its irregular operating, very big to ambient influnence again, especially medium-sized and small enterprises.Such as, to produce 10000 tons of crude benzol producing refined benzene enterprises per year, its sulfide emission amount is generally about about 500 tons/year, from amount, although not quite, if do not processed, its to environment and Human health effects then very large.
Three, summary of the invention
In view of the environmental protection of above-mentioned government and interested regulatory authorities are difficult to monitoring medium-sized and small enterprises desulfurization equipment, whether normal boot-strap runs these difficult problems, the invention provides a kind of intelligent terminal based on GPRS data transmission, realizes the online real-time monitoring to desulfurization equipment or supervision.
The existing power unit for the treatment of facility of semi-dry desulfurizing process mainly comprises circulating pump, slurry supply pump, air-introduced machine, atomizer, mixer, deduster, and its control system (i.e. switch cubicle) is primarily of circulating pump motor sensor, slurry supply pump electromechanical transducer, id-motor sensor, atomizer electromechanical transducer, mixer motor sensor, deduster electromechanical transducer.By the running status of Real-time Collection these facilities above-mentioned, can effectively supervise or supervise the operating condition of the treatment facility of semi-dry desulfurizing process.
Cardinal principle of the present invention: the intelligent terminal by exploitation with electrical signal collection and wireless transmission function, by the control system (i.e. switch cubicle) of its access desulfurization equipment in parallel, thus the on-off model of timing acquiring control system (namely judges when desulfurization equipment closes, when open and the duration that is energized), and synchronously utilize the galvanomagnetic-effect of electric equipment theoretical, by em induced current and the voltage of electromagnetic induction sensor signal perception smart machine, thus whether determining apparatus operates, by the microcomputer (CPU) of intelligent terminal inside, utilize the operating condition of given Mathematical Modeling determining apparatus.Again by GPRS wireless communication module, by intelligent terminal collection and process desulfurization equipment operating condition data, the receiving terminal (this terminal for other intelligent terminals such as regular handset, smart mobile phone, computer or iPad, thus can realize this facility remote supervisory or supervision) of government and interested regulatory authorities is sent to the form of SMS.
The present invention has the following advantages:
(1) this terminal cost is low, know-why simple, related accessory consumptive material is few, and all electronic devices and components all can be buied from ordinary electronic commodity market;
(2) this terminal only monitors semi-dry desulphurization facility operation operating mode, does not gather relevant environmental protection pollutant achievement data.Therefore, there is no the input of pollutant monitoring sensor, thus the machine input cost low, automatically run, and without operating cost, without the need to personal management safeguard etc.
(3) this terminal is in parallel with existing equipment accesses, and does not destroy, do not affect, do not disturb the normal operation of existing semi-dry desulphurization facility control system, realizes and slitless connection compatible with 100% of existing equipment control system.
(4) this terminal environments strong adaptability (severe environmental conditions such as sewage, waste gas can be applied), the advantage such as Signal transmissions is reliable, data transmission cost is low.Owing to utilizing GPRS common data transmission platform, thus do not have hardware facility requirement to data transmission, namely every have the place of mobile phone signal all can install, use.
(5) this end-on receiving unit requires low, and any portable computer and other GPRS terminals all can receive, and substantially do not need to drop into special expense and purchase receiving terminal, facilitate numerous regulator personnel to use simultaneously.Owing to utilizing GPRS common data transmission platform, as long as user is in GPRS range of signal, all can receives the information that intelligent terminal sends, not limit by space-time.
