Embodiment

[0037] Step 1: Calculate the Baume degree according to the crystallizer ambient temperature and the specific gravity of the saturated brine measured by the temperature sensor and the differential pressure transmitter.

[0038] Through sampling and testing, determine the Baume degree value of saturated brine under the environment of 15.6 degrees Celsius.

[0039] Step 2. After consulting a large number of test records, we drew the variation curve of Baume degree and temperature according to the test records, such as image 3 shown.

[0040] Step 3: Calculate the specific compensation correction value of Baume degree of saturated brine through the compensation relationship curve of Baume degree and temperature change.

[0041] After the method provided by the invention is adjusted through long-term experiments, the finally obtained Baume degree data is consistent with the data obtained by laboratory sampling and testing.

[0042] Years of production practice have proved that t...

Abstract

The invention discloses an on-line monitoring method of Baume degree during the production of potassic fertilizer, which comprises the following steps: measuring the temperature of saturated bittern in a crystallizer through a differential pressure transmitter to obtain the Baume degree; monitoring the environment temperature in real time through a temperature sensor, and drawing a Baume degree and temperature compensation relation curve; and correcting the Baume degree according to the curve to obtain the real-time and accurate Baume degree used for guiding the operation of the production site of the potassic fertilizer. Because the Baume degree is not tested by manpower, a great quantity of manpower and material resources are saved, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring, and in particular relates to an on-line monitoring method for Baume degree of saturated brine in crystallizers in potash fertilizer production. Background technique [0002] The crystallization process is a very important link in the production of potash fertilizers. This process determines the particle size and grade of the finished product, that is, determines the quality of the finished product. The Baume degree is an important parameter to control the particle size of potassium chloride. By monitoring the Baume degree, the production can be adjusted in time, so as to optimize the product and improve the efficiency. Because the Baume degree is greatly affected by temperature, under different temperature conditions, the Baume degree value of the same liquid will vary a lot. The Baume degree value is converted from the specific gravity value measured by using the differential pressure...
