Problems solved by technology

If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms

Embodiment Construction

[0036] Below in conjunction with embodiment the present invention will be further described:

[0037] 1. The production method of fly ash carbonized nutrient soil: (1) Input the ingredients of fly ash carbonized soil into the running mixer for stirring, and after stirring evenly, transport them to the roller machine and extrude them into irregular flake particles, flake particles The thickness of the carbonized soil is less than or equal to 6 mm; (2) The flake particles of fly ash carbonized soil are transported to the rotary carbonization furnace for carbonization treatment to become semi-finished products of fly ash carbonized soil. Control within 60 minutes; (3) Install a high-pressure mist water nozzle at the discharge port of the rotary carbonization furnace, and use high-pressure mist water to quickly extinguish the semi-finished fly ash carbonized soil that is burning anoxic, and the semi-finished fly ash carbonized soil is extinguished Finally, it is black fly ash carb...

Abstract

The invention discloses a method for producing coal ash carbonized nutrient soil. The key points of the technical scheme are that ingredients of coal ash carbonized soil are stirred and extruded into flaky grains, and the flaky grains are carbonized to form the coal ash carbonized soil, and then ingredients of the coal ash carbonized nutrient soil are granulated and sterilized, and are packaged to obtain the coal ash carbonized nutrient soil. The coal ash carbonized nutrient soil is prepared from coal ash, activated clay waste residue, attapulgite clay, bentonite, zeolite, pulverized waste, waterretted waste, vermiculite, diammonium phosphate, perlite, ferrous sulfate and super absorbent resin. The coal ash carbonized nutrient soil contains plenty of nitrogen, phosphorus, kalium, organic matters and microelements, is the high-quality nutrient soil which is complete in nutrition ingredients, high in fertilizer efficiency, nontoxic, sterile, harmless, free of foul smell and good in water conservation performance, and is suitable for flower, plant and seedling planting. The method for producing the coal ash carbonized nutrient soil is suitable for producing carbonized nutrient soil and nutrient substrates.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of fly ash carbonized nutrient soil. Background technique [0002] Most of the nutrient soil raw materials used by existing flower seedlings are mixed with materials such as mountain mud, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste and humus. The soil has not undergone reasonable ingredients, disinfection and sterilization, poor water and fertilizer retention, poor air permeability, and easy compaction. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings are also affected by viruses and bacteria in the soil. and newly sprouted weeds are not conducive to the normal growth and development of flower seedlings. [0003] Both phosphorus and potassium are essential nutrients for the growth of flower seedlings. Although the nutrient soil contains a certain amou...
