Problems solved by technology

However, due to the relatively large wind and sand in the northwest region, during the production process of the technical solution of the above-mentioned invention patent, since the sedimentation tank is open, a large amount of wind and sand will fall into the sedimentation tank, affecting product quality
At the same time, when natural sedimentation is used, the sedimentation tank occupies a large area and the sedimentation time is very long, resulting in an uncontinuous production process, resulting in a long production cycle and low production efficiency.
And it adopts steam drying, the equipment investment is large, the production cost is high, and it cannot be continuously produced

Embodiment Construction

[0022] like figure 1 As shown, the coal used for the production of sodium humate is pulverized by the pulverizer 1, and then enters the wind separation equipment 2, and the sand and stone in the coal are separated by using the different density of coal and sand. The wind separation equipment can use cyclone dust removal device. The coal after winnowing enters the reaction kettle 3 for reaction, and the reaction method adopts the present conventional method. The reacted material is put into the solid-liquid separator 4 for solid-liquid separation. The solid-liquid separation equipment can adopt rotary solid-liquid separator (produced by Luonan Environmental Protection Equipment Factory) or other forms of solid-liquid separation equipment. The separated liquid is pumped into the elevated tank 6 through the pump 5, and the material is continuously supplied to the concentration drum 8 through the elevated tank 6 to concentrate the material. The concentrated material enters the ...

Abstract

The invention discloses a humic sodium producing method through coal, which comprises the following steps: grinding; fanning; extracting; proceeding solid-liquid continual separation; condensing; drying. The invention improves the producing efficiency by 2-6 times, which is fit for condensing procedure through the residual heat of rolling cylinder drier.

Description

technical field [0001] The invention relates to a production process of sodium humate, in particular to a process for producing sodium humate with coal. Background technique [0002] At present, in the production process of sodium humate, the general process is: crushing, extraction, precipitation, and drying. For example, the title of the invention authorized by the China Intellectual Property Office on December 22, 2004 is [0003] "A Technology for Producing Sodium Humate with Coal", this invention provides a technology for producing sodium humate with coal. Its process is to crush the weathered coal into particles with a particle size of 1.5mm, and mix coal and water in proportion Add it into the reaction kettle, then add nitric acid prepared as a 1% solution, fully react for 5-8 minutes, start heating, and at the same time prepare sodium hydroxide solution proportionally, add it to the reaction kettle, and keep stirring until the liquid boils for 10-15 minutes Then st...
