Problems solved by technology

In the desulfurization technology, dry and semi-dry desulfurization are currently widely used desulfurization technologies, but the by-product of dry and semi-dry desulfurization - desulfurization ash (100 mesh-150 mesh dry powder), if not properly treated Comprehensive utilization will become a new pollutant. Due to the unstable nature of desulfurization ash, if it is stacked arbitrarily, it will not only occupy a large amount of land, but also cause groundwater pollution. Flying, cross-flow, and polluted air cause secondary pollution to the environment. Therefore, the resource utilization of dry and semi-dry desulfurization ash has become an urgent problem to be solved. There are differences between dry and semi-dry flue gas desulfurization technologies, but The composition of the desulfurization residue is largely the same, generally composed of calcium sulfite hemihydrate, calcium sulfate hemihydrate, calcium carbonate, calcium hydroxide and other small amount of inert substances and fly ash (soot)
At present, people still have doubts about the comprehensive utilization of desulfurization ash. Generally, it is made into desulfurization gypsum but needs to be calcined. Other applications include road construction, adjustment of soil pH value to improve soil, cement mixture and retarder. Desulfurization ash is different from fly ash in that it has a high sulfur content, and the application of various methods in China is not yet common. Therefore, the comprehensive utilization of desulfurization ash is still in the initial research stage in my country

Embodiment 1

[0010] Fireworks moisture-proof mud bottom: 5% desulfurized ash, 95% yellow mud.

[0011] Production process: Sun-dry or dry the yellow mud to a water content of 5%, then crush and sieve it into a particle powder below 3mm, mix the two according to the above ratio with a mixer (230 r / min) and stir evenly to form a mud bottom material , and then put the mud bottom material into the firecracker paper tube and squeeze and consolidate the mud bottom material into a mud bottom with a thickness of 8-15 mm through the firecracker mud bottom machine.

[0012] The above-mentioned firecracker moisture-proof mud bottom is subjected to mechanical percussion and extrusion structural strength test, and the structural strength is improved by 19% compared with the existing firecracker mud bottom, and then the moisture-proof experimental test is carried out according to the following method: Specifically, the concrete will be equipped with embodiment 1. The finished firecrackers with a moistur...

Embodiment 2

[0014] Fireworks moisture-proof mud bottom: 15% desulfurized ash, 85% yellow mud.

[0015] Production process: Sun-dry or dry the yellow mud to a water content of 10%, then crush and sieve it into a particle powder below 3mm, mix the two with a mixer (210 r / min) according to the above ratio, and then pass it through the fireworks The mud bottom machine is put into the firecracker paper tube and squeezed and consolidated.

[0016] The above-mentioned firecracker moisture-proof mud bottom was subjected to mechanical percussion and extrusion structural strength tests, and the structural strength was increased by 21% compared with the existing firecracker mud bottom. Compared with Examples 1 and 3, the structural strength was the best. Obvious failure, flameout, and sudden fire phenomenon occurred (the test method is the same as that in Example 1). By testing according to the method described in Example 1 in different regions of my country (south, such as Guangdong, Fujian, and G...

Embodiment 3

[0018] Fireworks moisture-proof mud bottom: 30% desulfurized ash, 70% yellow mud.

[0019] Production process: Sun-dry or dry the yellow mud to a water content of 7%, then crush and sieve it into a particle powder below 3mm, mix the two according to the above ratio and stir them evenly with a mixer (200 r / min), and then pass the fireworks The mud bottom machine is put into the firecracker paper tube and squeezed and consolidated.

[0020] The above firecracker moisture-proof mud bottom was subjected to mechanical percussion and extrusion structural strength tests, and the structural strength was increased by 19.8% compared with the existing firecracker mud bottom, and no failure, flameout, and fire failure did not occur in the moisture-proof test (the test method is the same as in the embodiment. 1) Compared with Examples 1 and 2, the moisture-proof effect is the best. After years of testing, in the north, the moisture-proof shelf life of the firecracker moisture-proof mud bot...

Abstract

The invention discloses a making method for a firework and firecracker dampproof muddy bottom. The firework and firecracker dampproof muddy bottom is prepared from, by weight, 5-30% of desulfurized fly ash and 70-95% of yellow mud. The firework and firecracker dampproof muddy bottom is prepared according to the method that the yellow mud is aired or stoved until the water content becomes 5-10%, then, the yellow mud is crushed and sieved, particle powder with the granularity not larger than 3 mm are formed, the desulfurized fly ash and the yellow mud are mixed according to the proportion and stirred to be uniform into a mud bottom material, and then, the mud bottom material is added into firework and firecracker paper cylinders and extruded and solidified through a firework and firecracker mud bottom machine into the firework and firecracker dampproof muddy bottom. According to the making method, the industrial waste desulfurized fly ash and the yellow mud are mixed, the structural strength of the firework and firecracker muddy bottom is increased by 20% or above, the dampproof shelf life is prolonged by 5 months or longer, and the problems that fireworks and firecrackers are damped within three months to the greatest degree in the firework and firecracker production, transportation and storage processes and the quality is affected are solved; according to the method, operation is easy and convenient, the recycling problem of desulfurized fly ash can be solved without consuming water and energy is solved, and in the firework and firecracker production industry with the local region being primary, and 200 thousand tons or above of desulfurized fly ash can be utilized within a year.

Description

technical field [0001] The invention relates to a method for making a firecracker mud bottom, in particular to a method for making a firecracker moisture-proof mud bottom based on desulfurization ash. Background technique [0002] The four adjacent counties of Shangli and Wanzai in Jiangxi, Liuyang and Liling in Hunan are the most important production areas of firecrackers and fireworks in my country. In the traditional production process of fireworks, the lower end of the fireworks is built with yellow mud, commonly known as "beating the mud bottom". The base is made of yellow mud mixed with a primer composed of magnesium oxychloride materials. The firecracker paper tube, leads and packaging are glued together. Yellow mud, anchoring agent, and glue all contain moisture and tend to get damp, especially in winter when the low temperature is not easy to dry, and in spring and summer when the air humidity is high, the gunpowder is easily damp and seriously affects the quality o...
