Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for adjusting the performance of cement for gypsum production in power plants, which has a setting test method to monitor the factors affected by the cement, so that the quality and performance of the cement can be guaranteed and the advantages are solved. The temperature and humidity cannot be detected during cement production, resulting in the problem that the quality of cement cannot be controlled

Embodiment 1

[0027]A preset value is set in the scattered temperature collection point, and the basis for judging the medium stability is: the difference between the minimum value and the maximum value in t1, t2, t3...tn is judged as stable within the preset value, and the stability is normal. The difference between the minimum value and the maximum value in t1, t2, t3....tn is judged as a stability imbalance outside the preset value. When the stability of t1, t2, t3....tn is normal, the scattered points The temperature collection point directly calculates the average value of t1, t2, t3....tn and sends it to the temperature detection terminal. When the stability is unbalanced, the scattered point temperature collection point directly sends the original data, namely t1, t2, t3.... tn to the temperature detection terminal, so as to remind the staff to check the absorption tower in time, solve possible problems in time, reduce losses, and improve safety. The average value of t1, t2, t3....tn ...

Abstract

The invention relates to the technical field of power plant gypsum, and discloses a cement performance adjusting method for power plant gypsum production. The method comprises the following steps: proper amounts of lime milk, soda ash, PFS and PAM are sequentially added to reclaimed water of an urban sewage treatment plant according to the quality of water coming from the urban sewage treatment plant in order to deeply treat the reclaimed water, the dosages of above reagents are correspondingly adjusted according to the quality of water coming from the urban sewage treatment plant and water treatment requirements, a mud-water mixture is subjected to mud-water separation through a variable-pore V-shaped filter tank, and clear water is conveyed to a clear water tank. The clinker components,admixture varieties, admixture use amounts, seasons and air temperatures during cement production, mill grinding working conditions and the like in the cement production process affect the quality andhe performances of produced cement, and adjustment of the ratio of the power plant gypsum, comprising an optimized formula of the gypsum and other raw materials, is carried out to timely correspondingly adjusting the formula in order to produce the stable high-strength and high-performance cement, so the method achieves an excellent effect.

Description

technical field [0001] The invention relates to the technical field of gypsum in power plants, in particular to a method for adjusting cement performance for gypsum production in power plants. Background technique [0002] The current technology for the use of gypsum in power plants is limited to the determination of the sulfur content and crystal water content in it, and never involves the production process and composition changes of gypsum in power plants. During the production process of gypsum in power plants, when the process changes, sulfur emissions in flue gas in different periods When the value changes, the temperature of the flue gas generated during the formation process is different, and the composition of the desulfurization gypsum changes. Through the microscopic inspection of the power plant gypsum composition sulfur + content, appearance color, changes in crystal water and changes in different conditions of the power plant gypsum formation process, a large nu...
