Embodiment Construction

[0010] The production process of the present invention is described as follows in conjunction with the accompanying drawings:

[0011] attached figure 2 In the original wet process, the weathered coal is not purified by selection and purification. After being crushed, it directly enters the reactor to react with water and NaOH. The main material consumption (tons of product) is:

[0012] Weathered coal 2.5-3 tons

[0013] NaOH 0.22 tons

[0014] Water 25-30 tons

[0015] 5 tons of standard coal

[0016] Electricity 40KWh

[0017] According to the data, the discharge pollutants produced by wet process per ton of products are:

[0018] Coal-fired slag: 2 tons

[0019] Waste (sewage) water: 4 tons

[0020] SO: 160 kg

[0021] Weathered coal residue: 1.5-2 tons

[0022] Smoke (powder) dust: 400 kg

[0023] Exhaust, ONx (nitrogen oxides), carbon monoxide, carbon dioxide:

[0024] 2000 cubic meters

[0025] NaOH and Na root: 0.12 tons

[0026] Taking a 2 ...

Abstract

On the basis of original wet production process said invention adopts full-sealed electric heat energy temp.-controlled reaction still and makes the leonardite undergo the processes of selection, purification, colloid milling and ultrasonic treatment, and adds the related chemical raw material to make reaction so as to obtain the invented product humic acid.

Description

Technical field: [0001] The invention belongs to a production method of chemical products, and relates to a production method of humic acid products. Background technique: [0002] Humic acid products have a wide range of uses. However, due to the limitations of raw materials and conditions for the production of humic acid in my country, since the mass production of sodium humate and potassium humate in my country at the end of the 1970s, no large-scale production has been formed. The production method and process are still manual workshops. No pretreatment, together with impurities - sand, soil, coal, directly into the open reactor, coal-fired heating reaction wet production process. This method consumes a lot of raw materials, discharges a lot of waste, causes serious pollution, poor product quality, small scale of operation, and high production cost. Invention content: [0003] The purpose of the present invention is to provide a humic acid production method with low p...
