Description
Technical field
The present invention relates to fuel-burning power plant desulfuration absorbing tower equipment, particularly the external liquid level emasuring device in a kind of heat-engine plant desulfurized absorption tower.
Background technology
In thermal power plant's limestone-gypsum wet desulfuration system, absorbing tower liquid-level is an important parameter of combustion adjustment. At present, domestic heat-engine plant desulfurized Systemic absorption tower liquidometer generally adopts pressure type liquid level meter, and this kind of liquidometer measuring error is big, and when unit load change, absorption tower serum density change, level error reaches ± more than 1000mm. Liquid level is too low can affect slurries oxidation effectiveness in tower, destroys slurries quality, once slurries quality is destroyed, desulfuration efficiency significantly declines, more than 3 days time increases equipment operation and could meet qualified discharge, nearly 20,000 degree of many power consumptions every day, it is generally required to could recover normal slurries quality; When liquid level is too high, slurries meeting overflow, time serious, a large amount of orrhorrhea flows into former flue, and multiple power plant occurred that absorption tower orrhorrhea flow to into booster fan, caused booster fan leaf destruction, and desulphurization system is forced to out of service for a long time, and financial loss crosses 1,000,000.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and provide a kind of liquid level accurately showing absorption tower, solve the conventional pressure type liquid level meter in absorption tower and measure inaccurate problem, avoid the problem causing because absorbing tower liquid-level is low slurries deterioration to affect sweetening effectiveness, avoid the external liquid level emasuring device in a kind of heat-engine plant desulfurized absorption tower of the problem absorbing structure deteriorate that the high-order overflow of inner slurries causes and environmental pollution simultaneously.
The present invention adopts following technical scheme to realize: the external liquid level emasuring device in a kind of heat-engine plant desulfurized absorption tower, comprise communicating pipe, liquid level mirror and coupling cock, regional connectivity is drenched by the spray on the first communicating pipe and absorption tower in the upper end of described liquid level mirror, and lower end is by the slurries region UNICOM of the 2nd communicating pipe and absorption tower.
The exit end of described 2nd communicating pipe is provided with coupling cock, described 2nd communicating pipe is also provided with rinse-system and unrestrained system, the flush valve that described rinse-system comprises washpipe and is arranged on washpipe, described unrestrained system comprises unrestrained pipe and the drain valve being arranged on unrestrained pipe.
Described liquid level mirror adopts toughened glass pipe liquid level mirror, and described liquid level mirror is provided with scale.
0.5m bottom the distance absorption tower, junction on described 2nd communicating pipe and absorption tower, the junction distance the highest liquid level 0.5m in absorption tower on described first communicating pipe and absorption tower.
Owing to adopting said structure, the present invention utilizes Communicating device principle to work, an extra laying liquid level mirror outside heat-engine plant desulfurized absorption tower, thus accurately show the liquid level on absorption tower, solve the conventional pressure type liquid level meter in absorption tower and measure inaccurate problem, avoid the problem causing because absorbing tower liquid-level is low slurries deterioration to affect sweetening effectiveness, avoid the problem absorbing structure deteriorate that the high-order overflow of inner slurries causes and environmental pollution simultaneously;
This device is arranged on outside absorption tower, and its top and absorption tower spray drench regional connectivity, bottom and slurries region, absorption tower UNICOM, it is ensured that liquid level emasuring device can correctly show absorption tower inside liquid level;
This device liquid level mirror adopts toughened glass pipe, and indicates scale, it is possible to intuitively read absorbing tower liquid-level accurately;
This device is furnished with flushing and unrestrained system, not only can rinse liquid level mirror at any time, it is ensured that its surface clean; Unrestrained can fall device remains slurries simultaneously, extract the inner up-to-date slurries in absorption tower, it is ensured that in device, serum density is consistent with serum density in tower, closely and correctly shows absorption tower inside liquid level.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is arranged on outside absorption tower.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1, be installed on for the present invention and absorb outside, comprised for the first communicating pipe 8, the 2nd communicating pipe 7, absorbing tower liquid-level go out pipe 9 and absorbing tower liquid-level inlet pipe 5, liquid level mirror 4, coupling cock 1, rinse-system, unrestrained system. First communicating pipe 8 went out pipe 9 with absorbing tower liquid-level to be connected, 2nd communicating pipe was connected with absorbing tower liquid-level inlet pipe 5 by coupling cock 1, first communicating pipe 8 was connected by liquid level mirror 4 with the 2nd communicating pipe 7, the flush valve 3 that described rinse-system comprises washpipe and is arranged on washpipe, described unrestrained system comprises unrestrained pipe and the drain valve 2 being arranged on unrestrained pipe. Liquid level mirror 4 adopts toughened glass pipe, and indicates scale, it is possible to intuitively read absorbing tower liquid-level accurately.
When measuring absorbing tower liquid-level, closing flush valve 3, drain valve 2, open coupling cock 1, absorption tower slurries enter measuring apparatus, and the liquid level of absorbing tower liquid-level is intuitive and accurate to be displayed in liquid level mirror 4;
After measurement, close coupling cock 1, open drain valve 2, drain the slurries in liquid level mirror 4, then close drain valve 2, open flush valve 3 and rinse about 5 minutes, close flush valve 3, open drain valve 2, drain liquid level mirror 4 liquid in pipe, rinse liquid level mirror complete.
The present invention thoroughly solves the inaccurate problem of absorbing tower liquid-level control, it is ensured that desulphurization system steady running, avoids the financial loss and potential safety hazard that cause because absorbing tower liquid-level is too high or too low.
