Problems solved by technology

[0005] The accumulation of coal gangue not only occupies the land, but also pollutes the air by spontaneous combustion or causes fires, polluting the atmosphere, and the stacking of coal gangue in the open air will generate a lot of dust. It will be weathered and crushed. In addition, coal gangue will disintegrate after absorbing water, so it is easy to generate dust. Under the action of wind, it will deteriorate the quality of the atmosphere in the mining area

Embodiment Construction

[0037] Below in conjunction with embodiment the present invention will be further described:

[0038] 1. The production method of coal gangue carbonized nutrient soil: (1) Input the ingredients of coal gangue carbonized soil into the running mixer for stirring, and after stirring evenly, transport them to the roller machine and extrude them into irregular flaky particles. The thickness of the flaky particles is ≤6 mm; (2) Transport the flake particles of coal gangue carbonized soil to a rotary carbonization furnace for carbonization treatment to become a semi-finished product of coal gangue carbonized soil. The carbonization temperature in the rotary carbonization furnace is controlled at 300-400 ° C, and the carbonization time is controlled at 60 minutes ; (3) Install a high-pressure mist-like water nozzle at the discharge port of the rotary carbonization furnace, and use high-pressure mist-like water to quickly extinguish the semi-finished coal gangue carbonized soil that is ...

Abstract

The invention discloses a production method for coal gangue carbonized nutrient soil. The main points of a technical scheme of the invention are as follows: stirring the ingredients of coal gangue carbonized soil and carrying out squeezing to obtain flaky particles; carrying out carbonization treatment so as to obtain the coal gangue carbonized soil; then subjecting the ingredients of the coal gangue carbonized nutrient soil to granulation and sterilization; and carrying out packaging so as to obtain the coal gangue carbonized nutrient soil. The coal gangue carbonized nutrient soil is composed of coal gangue, waste activated carclazyte residues, attapulgite clay, bentonite, zeolite, smashed wastes, water-retted wastes, vermiculite, diammonium phosphate, perlite, ferrous sulfate and super absorbent resin. According to the invention, the coal gangue carbonized nutrient soil contains a great amount of nitrogen, phosphorus, potassium, organic matters and trace elements, is high-quality nutrient soil with complete nutrition ingredients, high fertilizer efficiency, no toxicity, asepsis, harmlessness, odorlessness and good water-retaining property, and is suitable for planting of flowers and seedlings; and the production method for the coal gangue carbonized nutrient soil is applicable to production of carbonized nutrient soil and nutrient media.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of coal gangue 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 ...
