Description
Technical field
The utility model relates to a kind of environment monitoring equipment, especially a kind of pumping equipment for on-line monitoring system of flue gas discharge.
Background technology
Along with the fast development of China's economy, environmental pollution is also more and more serious, especially because of fire coal, is discharged into the sulphuric dioxide (SO in atmosphere
2) and oxides of nitrogen (NO
x) sharply increase, have a strong impact on the healthy of people, for this reason, country has put into effect relevant legal documents, strictly controls the discharge of pollutant, especially the large Enterprises solar obligation on-line monitoring system of flue gas discharge to some pollutant discharge amounts." the Chou Qu – – cryochem " on-line monitoring system of flue gas discharge of the normal employing of this class monitoring at present, this system is a kind of to exhaust gas components (SO
2, NO
x, flue dust) and the relevant Gas Parameters instrument that carries out on-line automatic continuous monitoring, due to SO
2gas has adsorbability and dissolubility, so must first remove fine grained dust and the moisture in flue gas before detecting, gas sampled to be detected is carried out to pre-service, for guaranteeing the accuracy of gas sampled measurement data, therefore particularly important to the processed of flue gas in preprocessing process, gas sampled is at the condensed fluid produced after condenser dehydration in system, need to be discharged in specified containers through specific device, the tradition pumping equipment adopts the peristaltic pump discharge opeing, because condensed fluid is faintly acid, peristaltic pump tube is corrosive, the long-time tube wall that uses is easily aging, peristaltic pump belongs to moving component simultaneously, in the continuous motion process, the peristaltic pump creep-resistant property progressively reduces, also easily cause the discharge opeing inefficiency, peristaltic pump tube needs periodic replacement, if the operating mode that smoke moisture is larger, also must there be 2 peristaltic pumps to work simultaneously, otherwise the system discharge opeing is not smooth, system works stability and apparatus measures accuracy are had a great impact, also increase consumptive material and the maintenance cost that has strengthened system.
The utility model content
The utility model provides a kind of pumping equipment that can effectively discharge condensed fluid in smoke on-line monitoring system.
In order to reach above purpose, the pumping equipment of a kind of on-line monitoring system of flue gas discharge of the utility model comprises liquid storage bottle, discharging tube, positive displacement pump and support, liquid storage bottle is fixed on support, liquid storage bottle is connected with positive displacement pump by discharging tube, it is characterized in that a capacitor type proximity switch is fixed on support, its induction end face is pressed close to the lateral wall of liquid storage bottle, and capacitor type proximity switch is connected with control system by wire with positive displacement pump.
This pumping equipment changes and causes the conversion of the electric capacity in the capacitor type proximity switch loop in device by the liquid storage bottle liquid level, and signal is passed to control system, control system is sent the positive displacement pump work order of one-period time, condensate water in liquid storage bottle is carried out to discharge opeing, improved sensitivity and the system rejection to disturbance ability of monitoring device; Substitute the peristaltic pump of not stopping work in the past always and doing with the positive displacement pump of periodic duty, in the serviceable life of having improved positive displacement pump, the while has also been reduced the maintenance cost of system.
Principle of work:
As shown in Figure 1, the condensate water that the system condensing device produces enters liquid storage bottle, after in liquid storage bottle, liquid level rises to certain altitude, under inductive action, electric capacity conversion in the capacitor type proximity switch loop, its signal passes to control system, control system will be sent enabled instruction to positive displacement pump by the programmed instruction set, thereby positive displacement pump is discharged to condensed fluid in specified containers, positive displacement pump quits work because electric capacity converts after completing a discharge opeing work period, condensed fluid is assembled again in liquid storage bottle, waits for the enabled instruction next time of control system, so circulation.
The accompanying drawing explanation
Fig. 1 is the structural representation of the online flue gas monitoring system of the utility model pumping equipment
In Fig. 1: 1, support, 2, capacitor type proximity switch, 3, liquid storage bottle, 4, discharging tube, 5, positive displacement pump, 6, control system
embodiment:
As shown in Figure 1, the liquid storage bottle 3 that a glass material is made is arranged on support 1 upper end, liquid storage bottle 3 is connected with positive displacement pump 5 by discharging tube 4, is that liquid storage bottle 3 lower end leakage fluid drams are connected to the entrance of positive displacement pump 5 by discharging tube 4, and the outlet of positive displacement pump 5 is connected in waste fluid container.In addition, separately there is a capacitor type proximity switch 2 to be arranged in the mounting hole of support 1 side, the position of control capacittance type approach switch 2, make it highly suitable, its induction end face is pressed close to glass liquid storage bottle 3 outer walls, be fixed in mounting hole after vertical and liquid storage bottle 3 lateral walls of capacitor type proximity switch 2 are upright position, and capacitor type proximity switch 2 is connected with control system 6 by wire with positive displacement pump 5.In the debug process of whole online flue gas monitoring exhaust system, the sensitivity of capacitor type proximity switch 2 in pumping equipment is set according to the humidity size of flue gas operating mode, and the time of 5 one discharge opeing work periods of positive displacement pump.For preventing the corrosion of condensed fluid, discharging tube, the positive displacement pump critical component adopts resistant material.
