Utility model content
Its object of the utility model is just to provide a kind of PH to count the cooling device of measurement electrode, has the service life extending measurement electrode, reduces maintenance cost, reduce labour intensity, the feature eliminated safe hidden trouble.
Realize above-mentioned purpose and the technical scheme taked, comprise measuring media pipeline, described measuring media pipeline is handled valve 1 and is connected serpentine coil upper end import in cooling device, valve 2 is handled in the outlet of serpentine coil lower end, flowmeter connects flow cell lower interface, PH counts measurement electrode and is contained on flow cell, and flow cell side is drawn mozzle and entered sour water ditch; Be provided with pump seal water inlet and cooling water inlet bottom described cooling device, cooling water handles valve, magnetic valve connects cooling water inlet, and magnetic valve two ends are provided with bypass hand valve 3; Described cooling device upper end is provided with overfall, and overfall exports and connects pond, is provided with liquid level gauge and immersible pump in pond; Described PH measurement amount electrode output connecting secondary instrument, secondary meter output connected electromagnetic valve.
Compared with prior art the utility model has the following advantages.
Scene can adopt manually, automatic control scheme, flexibility and reliability, improvement cost is not high, like this, has both reduced the operating temperature of medium, facilitate again demarcation and the replacing of measurement electrode, extend the service life of measurement electrode, reduce maintenance cost, decrease the quantity in stock of spare part, simultaneously cooling water obtain secondary even three times make full use of, additionally reduces the generation of potential safety hazard.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic diagram.
Detailed description of the invention
Comprise measuring media pipeline, as shown in Figure 1, described measuring media pipeline is handled valve 1 and is connected serpentine coil upper end import in cooling device, valve 2 is handled in the outlet of serpentine coil lower end, flowmeter connects flow cell lower interface, PH counts measurement electrode and is contained on flow cell, and flow cell side is drawn mozzle and entered sour water ditch; Be provided with pump seal water inlet and cooling water inlet bottom described cooling device, cooling water handles valve, magnetic valve connects cooling water inlet, and magnetic valve two ends are provided with bypass hand valve 3; Described cooling device upper end is provided with overfall, and overfall exports and connects pond, is provided with liquid level gauge and immersible pump in pond; Described PH measurement amount electrode output connecting secondary instrument, secondary meter output connected electromagnetic valve.
Embodiment
According to original equipment operation conditions, get mouth by pipeline and stop valve, impulse mozzle are installed by measurement electrode away from process pipe, the top of medium from cooling device is flowed into, flow out from cooling device bottom after one section of serpentine coil (processing with Φ 14 × 2 stainless steel tube), through flow cell, flowmeter, then discharge after flowing through measurement electrode, the pH value of measurement electrode measuring media, the millivolt value recorded feeds back to secondary meter display, and secondary change is simultaneously sent and outputted to DCS display.Cooling water flows into from the bottom of cooling device, and top is flowed out, and utilizes heat exchange to reduce the temperature of medium.In order to cost-saving, make full use of water resource, by the flow export of the sealing water of pump, access cooling device cooling water inlet.In order to better control medium temperature, cooling device is set up another cooling water inlet, control it by magnetic valve and open and close the inlet controlling supplementary cooling water, regulate cooling water temperature in cooling device, reach the temperature regulating measuring media.
As shown in Figure 1,
1, measuring media pipeline: get mouth from measuring channel, welding hand valve 1, impulse mozzle Φ 14, be connected from cooling device upper opening welding mozzle with the serpentine coil in cooling device, cooling device is drawn again through apparatus for supercooling lower openings impulse mozzle, connect hand valve 2, flowmeter, flow cell lower interface, flow cell side mouth connects impulse mozzle and enters sour water ditch, and decontaminated water field processes;
2, cooling water pipeline a: road is accessed bottom cooling device from pump seal water out impulse mozzle Φ 20, valve, magnetic valve, from cooling water pipe, with impulse mozzle DN10, are taken in another road, bottom access cooling device, for can manually, automatically control, make a bypass hand valve 3 at magnetic valve place, magnetic valve is exported by secondary meter temperature limit and controls, temperature is high 45 DEG C, secondary meter exports Controlling solenoid valve and obtains electric opening, and during low 35 DEG C of temperature, secondary meter exports Controlling solenoid valve dead electricity and cuts out; Cooling device inner cooling water utilizes nature overflow, and flow into pond by DN50 pipeline, pond liquid level height is controlled by liquid-level switch, and high immersible pump in limited time starts discharges, and during lower bound, immersible pump stops.
After installing, first to measuring media pipeline-cleaning, after debug again, during debugging, PH is counted measurement electrode and loads onto on flow cell, on secondary meter design temperature high limit 45 DEG C, lower bound 35 DEG C; First manual unlocking bypass hand valve 3, allows cooling water fill cooling device, cuts out bypass hand valve 3, access pump seal water; Now, open measuring media import hand valve 1, spend about 2 minutes, slowly adjust flux meter remote holder valve 2 again, make rate-of flow be 1L/min, have a mind to reduce cooling water inflow, temperature is elevated to 45 DEG C, magnetic valve obtains electric, open, have a mind to increase cooling water inflow, temperature declines, lower than 35 DEG C, magnetic valve dead electricity is closed; Pond liquid level switch, regulates and controls according to pond liquid level demand.
Through cooling device like this, the service condition of electrode is easy to meet, and electrode can use ordinary temp type, reduces equipment purchase cost; Medium temperature, generally at about 35 DEG C, is beneficial to the use of electrode, extends electrode life; Flow can control, and is not easy to damage electrode; Demarcate convenient, safety, reduce labour intensity.
