Embodiment 1

[0019] Example 1: Add 40%wt of sandy red clay, 50%wt of pig bone meal and 10%wt of ordinary clay into a ball mill for uniform mixing, then add 0.008% of the total weight of the above three kinds of raw materials into the ball mill Plastic film fuel ashes and organic cellulose with a total weight of 2% of the three raw materials were ball milled and rolled for 1-2 hours to obtain a mixture, and then the mixture was added to a mud mill and tung oil with a total weight of 3.5% of the above three raw materials was added for vacuum The mud is smelted to make a thick mud, which is extruded in an extruder mold to form a tubular wet billet, and the wet billet is dried at a temperature of 80-120°C to make a semi-finished billet. Then put the semi-finished body into the kiln and heat it at 800-1200°C for 6-8 hours to burn into tubular packing, and then cut it into tubular packing of different lengths according to user requirements. The packing that present embodiment 1 is made is throug...

Embodiment 2

[0021] Example 2, three raw materials of 30%wt mud laterite, 55%wt bovine bone powder and 15%wt ordinary clay were added into a ball mill and mixed uniformly, and then 0.006% of the total weight of the above three kinds of raw materials was added into the ball mill. Plastic film fuel ashes and organic cellulose with a total weight of 3% of the three raw materials were ball milled and rolled for 1-2 hours to obtain a mixture, and then the mixture was added to the mud mill and tung oil with a total weight of the three raw materials of 5% was added for vacuum The mud is smelted to make a thick mud, which is extruded in an extruder mold to form a tubular wet billet, and the wet billet is dried at a temperature of 80-120°C to make a semi-finished billet. Then put the semi-finished body into the kiln and heat it at 800-1200°C for 6-8 hours to burn into tubular packing, and then cut it into tubular packing of different lengths according to user requirements. The packing that present ...

Embodiment 3

[0023] Example 3, three raw materials of 50%wt cooked red clay, 30%wt pig bone powder and 20%wt pottery clay were added into a ball mill for uniform mixing, and then 0.007% of the total weight of the above three raw materials was added to the ball mill. The film fuel ash and the organic cellulose of 1% of the total weight of the three raw materials were ball milled and mixed for 1-2 hours to obtain a mixture, and then the mixture was added to the mud mill and tung oil of 6.5% of the total weight of the above three raw materials was added for vacuum refining The mud is made into thick mud, and the mud is extruded in the extruder mold to form a tubular wet billet, and the wet billet is dried at a temperature of 80-120°C to make a semi-finished billet, and then Put the semi-finished body into the kiln and heat it at 800-1200°C for 6-8 hours to make tubular packing, and then cut it into tubular packing of different lengths according to user requirements.

Abstract

The invention discloses a high-efficiency filtering and purifying environmental-friendly filling material which is prepared from 30-60 wt% of red soil, 10-20 wt% of bone powder and 10-20 wt% of clay as raw materials by adopting the following steps of: uniformly mixing the three raw materials of the red soil, the bone powder and the clay in a ball mill; then, respectively adding plastic film dottle accounting for less than 0.01% of total weight of the three raw materials and organic cellulose accounting for 1-3% of total weight of the three raw materials into the ball mill for ball milling and rolling to obtain a mixture; and adding the mixture into a pug mill, adding tung oil accounting for 3-7% of the total weight of the three raw materials into the mixture for vacuum pug milling to produce thick pug, extruding and forming the pug in an extruder mold to produce wet blanks, and baking the wet blanks in the sun to produce semi-product blanks. The filling material can form a stable high-activity biological film, and can ensure that refractory microorganisms, metal ions and the like in matter to be treated can be favorably adsorbed and collected in holes of a filter material, thereby improving the treatment effect of filtration and purification, enhancing the compression strength of the filling material, prolonging the filtration and purification period, improving the filtration and purification effect, and lowering the treatment cost.

Description

technical field [0001] The invention relates to a packing for gas-liquid filtration and purification, in particular to a high-efficiency filter and purification environmental protection packing with light specific gravity and good filtration and purification effect. Background technique [0002] In petrochemical oil refining, fine chemical industry, smelting, environmental protection, building materials, pharmaceutical and gas industries, due to the requirements and needs of product quality, process flow and comprehensive treatment and utilization, no matter in oil refining, chemical production, iron and steel smelting, sewage and wastewater In the process of gas purification, exhaust gas emission, etc., various forms of filtration and purification treatments are almost required. For example, ceramsite, porcelain sand and quartz sand are commonly used in various drying towers, washing towers, desulfurization towers and rectification separation towers for the production of ch...
