Description
Technical field
The utility model relates to a kind of serosity density measurement device, particularly a kind of lime stone slurry of limestone wet-process desulfurization, gypsum slurries density measuring equipment.
Background technology
At present, adopt 1 basically for the measurement of absorption tower gypsum slurries density) the Υ gamma ray density meter; 2) coriolis force (Corolis) densitometer; 3) ultrasonic densitometer; 4) four kinds of methods of differential pressure densimeter are carried out the on-line measurement scheme on the gypsum slurries discharge line, measuring equipment mainly adopts coriolis force densitometer etc., wherein the Υ gamma ray density meter is made up of three parts: a. Υ ray irradiation source (caesium 237), b. probe, c. transmitter; Principle is that the intensity of ray weakened after the Υ ray that sends of radioactive source was absorbed by slurries, and the variation of transmitted intensity and the density of slurries are proportional, thereby calculate the density advantages of slurries: simple installation, measure accurately, noncontact, nothing wearing and tearing and corrode; Shortcoming: psychologically to the fear of Υ ray, the agreement that need obtain labour safety and hygiene department could use, the need reinforcement is to the management of radioactive source.2) coriolis force (Corolis) densitometer, a. fundamental measurement principle: coriolis force densimeter measurement pipe vibrates with certain resonant frequency continuously, vibration frequency changes with the variable density of fluid, so resonant frequency is the function of fluid density, can get corresponding density output signal thus.B. the pattern of measuring sensor and selection: the sensor of single straight tube: bore DN40 or DN50, measuring tube material: titanium, advantage: safety, precision height; Shortcoming: need join bypass and do measuring tube, need to add hand valve before and after the mass flowmeter; The bore of measuring sensor is little, and slurries have wearing and tearing and corrosion to it; Possibility of jamming is arranged; Price is higher; After valve opening diminishes.Because flow velocity is the gypsum or the lime slurry of concentration higher (about 25%), cause the obstruction of bypass valve or densimeter measurement pipe easily, when bypass valve stops up, the densitometric flow velocity of flowing through strengthens, and can cause densitometric wearing and tearing, when the densitometer fouling is stopped up, must wash, therefore the operation maintenance personnel should often go to observe the variation of this measured value, and frequent again washes, so that density measure can't reach continuously and be stable.3) ultrasonic densitometer, many years of experience prove that the degree of the suspended particulate substance in mud liquid is directly proportional with the decay of ultrasound wave in mud liquid.Ultrasonic densitometer uses this technology directly to measure the concentration of suspended particulate substance.Advantage vertically is installed: simple installation, almost there is not choked flow piece in the measuring tube, crushing is little, and it is little to wear and tear; Shortcoming: need do bypass, price is higher; 4) differential pressure densimeter calculates density by the differential pressure of slurries: △ P=ρ gh, ρ: serum density, kg/m3; G: constant, 9.8; H: measuring tube (slurries) highly, m; △ P: the measured value of differential pressure transmitter, Pa; Advantage: cost is low, shortcoming: the pipe arrangement complexity.
