What kind of form of limestone slurry tank density meter is accurate

In the domestic desulfurization industry, the limestone slurry density meter uses more differential pressure density meter, according to the different installation environment, there are two forms of MH5300 differential pressure density meter, differential pressure type has four forms of Menghui top-mounted density meter, Menghui double flange side-mounted density meter, Menghui single flange elbow density meter, Menghui pipeline density meter, the other is Menghui tuning fork density meter, the measurement principle is tuning fork resonance, According to the different frequencies of vibration reception in different media to determine the density of the medium, these two kinds of density meters are directly displayed density value, the output is 4-20mA, the remote transmission with HART protocol, the installation is simple and convenient! In terms of accuracy, the accuracy of the tuning fork density meter will be higher, and the accuracy of the general tuning fork density meter will be relatively expensive.

The problem is: the mass flow meter will be washed and worn by slurry, which will reduce the service life, the operating cost is large, and the on-site maintenance will also be large due to the blockage problem;

Due to the potential harm to the human body, the nuclear densitometer is strictly supervised and troublesome, and it is rarely used;

Ultrasonic density meter is a new type of desulfurization slurry density meter, which is not affected by wear, blockage and other problems, and is an ideal way to measure the density of desulfurization slurry.

Note: Control the flow rate. However, the large flow rate wears the instrument and shortens the life, and the flow rate is small and easy to block, increasing the amount of maintenance.

Due to the influence of wear and blockage, there are fewer and fewer factories that choose mass flow meters for desulfurization systems, and ultrasonic density meters are not affected by wear and blockage, which is very suitable for the application of power plant desulfurization systems, you can consider.

Measure the density or use a professional density meter to measure it!

Each has its own job.

Density is concentration.

There is a calculation formula, gypsum slurry or desulfurizer slurry, the formula is different.

The density of gypsum and water in limegypsum desulfurization can be discharged when appropriate, and the density is not good for the equipment. This is not a fixed value, if the sulfur dioxide content has been high, it is appropriate to have more gypsum, and the density is smaller, and limestone powder is wasted. Generally, power plants are in the range of 1170-1180.

There is a calculation formula, depending on what kind of slurry you are, gypsum slurry or desulfurizer slurry, the formula is different.

The amount of lime added to the double alkali desulfurization is generally controlled according to the Baumé degree of the circulating fluid, and the Baumé degree should always be below 15. The larger the Baumé degree, the more lime is added, resulting in waste, turbidity of the supernatant, excessive alkalinity, and gradual scaling of the inner wall of the absorption tower, which affects the absorption effect. At the same time, the amount of alkali added is controlled, which is generally kept between pH 8 and 10 of the circulating solution after lime is added, and the minimum should not be less than 8

Hope it helps.

If the slurry density meter is not allowed to be used mainly under what process conditions, if it is used on the desulfurization slurry, the measurement value of the density meter is large, it will be a waste of slurry if the pulping is not completed, if the measurement value is small, the desulfurization effect will be incomplete, the use of Menghui density meter to measure the slurry density meter, if the accuracy requirements are high, you can use the MH5300 tuning fork density meter.

What are the disadvantages of the ENV200C clamp-on density meter? Its practicality is really good, wess Korean, environmental protection in Iraq.

In fact, it is a large cylinder jar, preferably two, with a pipe at the bottom, which can be connected during maintenance. CAD drawings do not support uploading, there are centralized control screen diagrams you can refer to.

Personally, I think that limestone slurry is more abrasive, so wear-resistant materials are used. However, limestone slurry also has a higher chloride concentration. Therefore, the problem of corrosion also needs to be considered.

In the face of these two situations, it is also possible to choose a ceramic valve, but it is relatively high, and the diaphragm valve is generally used for limestone slurry pressure measurement due to its good sealing and strong corrosion resistance. Therefore, in most cases, the valves for transporting limestone desulfurization slurry are lined with rubber, which can be wear-resistant and anti-corrosion.
