Compensation algorithm for calculating dosage of paper machine chemicals or auxiliary materials

Abstract

The invention discloses a paper machine chemical or auxiliary material dosage calculation compensation algorithm. The algorithm comprises the following steps: step 1, paper machine yield detection; 2, calculating the yield of the surface layer; step 3, core layer yield calculation; step 4, bottom layer yield calculation; 5, calculating a correction coefficient; step 6, yield correction and compensation; according to the method, the actual yield of the paper machine is detected and calculated through the QCS system, then the calculated yields of the surface layer, the core layer and the bottom layer of the headbox are calculated through a traditional formula, and then the correction coefficient is calculated by combining the actual yield, detected and calculated through the QCS system, of the paper machine. And the calculated output of the surface layer, the core layer and the bottom layer of the headbox is corrected by using the correction coefficient, so that errors are reduced, the output is obtained more accurately, the problem of inaccurate dosage of chemicals and auxiliary materials caused by large absolute dry stock deviation in multi-layer stock calculation is effectively avoided, resource waste is reduced, and the cost is reduced. Accurate addition of chemical auxiliary materials is achieved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a calculation and compensation algorithm for the consumption of paper machine chemicals or auxiliary materials. Background technique [0002] Paper machine refers to all kinds of paper machinery, that is, machinery for producing and processing household paper and office paper. There are many types of paper machines, which can be divided into paper forming machinery and paper processing machinery. Among them, paper forming machinery includes: Napkin machine, toilet paper machine, facial tissue machine, mini paper towel machine, paper towel machine, non-woven fabric rewinder, square tissue machine, handkerchief paper machine, etc., and paper processing machinery includes: rewinder, paper cutter, sorting Cutting machines, etc., paper forming machinery can produce perfect tissue paper only when used in conjunction with paper processing machinery; [0003] In the papermaking proc...

Problems solved by technology

[0003] In the papermaking process of the paper machine, the amount of chemicals and auxiliary materials used is generally calculated according to the output. Most of the calculation formulas are: absolute dry pulp = flow * concentration / 1000 * 60 to calculate the amount of chemicals used, Since the flow rate and concentration are measured by on-site process instruments, sometimes there will be detection deviations, resulting in large deviations in dry pulp, which will affect the use of auxiliary materials, resulting in unnecessary waste of resources and increased production costs. At the same time, it is difficult to achieve the quantity of chemicals and auxiliary materials. Precise control reduces production efficiency
