Abstract
The utility model relates to a measuring device of water consumption in a limestone-gypsum wet desulphurization device. The measuring device of water consumption in the limestone-gypsum wet desulphurization device comprises all water consumption pipelines of the limestone-gypsum wet desulphurization device. The water consumption pipelines are all connected with a process water tank which is provided with a water supplement pipe. The water supplement pipe is provided with an ultrasound flowmeter probe and an ultrasound flowmeter. The ultrasound flowmeter probe is connected with a DCS control system of the limestone-gypsum wet desulphurization device. The measuring device of water consumption in the limestone-gypsum wet desulphurization device has the advantages of solving the problems that the number of water consumption units of the limestone-gypsum wet desulphurization device is large, and part of the water consumption units do not meet requirements of measurements so that water consumption in the limestone-gypsum wet desulphurization device is incapable of being measured.
Description
Technical field:
The utility model relates to the measurement mechanism of water consumption in a kind of thermal power plant " limestone-gypsum desulphurization system " Performance Assessment test.
Background technology:
" limestone-gypsum desulphurization system " is the flue gas desulfurization technique that present thermal power plant extensively adopts, its performances acceptance test basis standard DL/T 998-2006 " wet desulfurization of flue gas by limestone-gypsum method device performance acceptance test specification ".Water consumption is an index of " limestone-gypsum desulphurization system " performances acceptance test, but the concrete test method of undeclared water consumption in standard.
Desulfurizer fresh water (FW) user is the wash-down water of absorption tower moisturizing, slurry circulating pump flushing of pipeline, the road flushing of lime stone flow inlet, gypsum extraction pump flushing of pipeline, the flushing of GGH low-pressure water, the flushing of absorption tower demisting device, limestone slurry nozzle for liquid, absorption tower pH meter and densitometer etc.Various and the not timing water of water unit is tested all user's water consumptions and then adds up total water consumption workload huge, can't realize in practical operation.
Summary of the invention:
The utility model provides the measurement mechanism of water consumption in a kind of limestone-gypsum desulphurization system for overcoming above-mentioned the deficiencies in the prior art, and its test findings is accurate, can test the most easily thermal power plant's " limestone-gypsum desulphurization system " water consumption.
The purpose of this utility model is to adopt following technical proposals to realize:
The measurement mechanism of water consumption in a kind of limestone-gypsum desulphurization system, each water pipeline that comprises desulfurizer, each water pipeline all connects the technique water tank, the technique water tank is provided with filling pipe, filling pipe is provided with probe of ultrasonic flowmeter and ultrasonic flow meter, and probe of ultrasonic flowmeter is connected with desulfurizer DCS control system.
The beneficial effects of the utility model are: it is various to have solved desulfurizer water unit, and part water unit does not possess test condition, the difficult problem that the desulfurizer water consumption can't be measured.

The measuring method of water consumption in a kind of limestone-gypsum desulphurization system, concrete steps are:
1. the average discharge F when ultrasonic flow meter is measured the moisturizing of technique water tank is 100m
3/ h.
In desulfurization DCS control system collection technology water tank water compensating valve open instruction time data t
1Be 10h, t
2Be 12h, t
3Be 11h, t
4Be 13h, t
5Be 9h.
3. calculate technique water tank water compensating valve and open T.T. t=t
1+ t
2+ t
3+ t
4+ t
5=10+12+11+13+9=55h.
4. calculate operating condition of test T.T..Require test to carry out in DL/T 998-2006 standard 7 days, T=7 * 24h=168h.
5. calculating water consumption, Q=(F * t) ÷ T=(100 * 55) ÷ 168=32.7m
3/ h.
