Description

Technical Field

[0001] The present invention relates to the field of a closed conveying device for lime powder pelletizing in the calcium carbide production industry, and in particular to a method for decomposing the response area of a number sequence of a spray gun elbow for a closed conveying pulverized coal process supporting lime powder pelletizing. Background Art

[0002] As is well known, the main raw materials for calcium carbide production are carbonaceous materials and limestone. Dust problems are caused during the production and transportation of lime powder. Through research on the positive pressure dense phase pneumatic conveying technology and the fluidization elbow technology, the layout of a lime powder buffer bin and a spray gun purge process pipeline is designed and established to achieve the closed environmental protection conveying of lime powder, completely eliminating dust spillage and effectively improving the working environment of the factory area. During the calcium carbide production process, limestone is mainly calcined in a lime kiln: air enters from the top of the kiln chamber and flows downward under the suction of the dust collector, while being preheated by the hot limestone. When reaching the calcination zone, the pulverized coal and gas transported by the spray gun here are mixed and immediately burn when contacting the red-hot limestone. The limestone is thermally decomposed to form lime. The length of the spray gun and the diameter change of the elbow determine the position of the calcination zone in the kiln chamber. Currently, the problem is that the control of the length of the elbow part and the size of the diameter change part of the spray gun part is extremely important, and the elbow part is not a regular and standard elbow. The spray gun elbow made by using a standard stamping machine or a pipe bender may be too short during production use, which may cause the calcination zone to move upward, the lime to be easily overburned, the waste gas temperature to be too high, and damage the dust removal cloth bag of the kiln body; if the spray gun elbow is too long, it may cause the calcination zone to move downward, the pulverized coal cannot be fully burned, the lime is underburned, the channel temperature is too high, and the kiln channel is damaged, thus posing a great safety hazard to production.

[0003] Currently, as is well known, if a sequence of numbers, starting from the second term, the difference between each term and its previous term is equal to the same constant, this sequence of numbers is called an arithmetic sequence, and this constant is called the common difference of the arithmetic sequence, and the common difference is usually represented by the letter d. The general formula for the nth term of a general arithmetic sequence: an = a1 + (n - 1)d; and the sum of the first n terms of an arithmetic sequence: Let the sum of the first n terms of the arithmetic sequence be Sn, that is, Sn = a1 + a2 +... + an; then Sn = na1 + n(n - 1)d / 2. Its calculation is commonly used in the conventional calculation where the difference between each term and its previous term is equal to the same constant in a conventional process. Summary of the Invention

In the spray gun bend pipe sequence response area decomposition, the response speed of the radius value and the real-time data decomposition are improved.

[0058] The method of calculating by dividing areas according to the arithmetic sequence calculation makes the bending radius of the nozzle bend pipe within a controllable range. The above method strictly controls the length of the bend pipe part and the size of the variable diameter part of the spray gun part, so that each bend pipe part within the area is not a regular and standard bend pipe, solving the problem that the spray gun bend pipe made by using a standard stamping machine or bend pipe machine has a standard right angle in the spray gun bend pipe part and the problem that the spray gun bend pipe is too short.
