Description
Technical field
The novel production technique that relates to a kind of Sodium salts humic acids of the present invention, particularly a kind of processing method of producing Sodium salts humic acids with coal.
Background technology
At present, in the production process of Sodium salts humic acids, general technological process is: pulverize, extract, precipitate, dry.Authorized the invention disclosed name to be called on December 22nd, 2004 as China Intellectual Property Office
" a kind of technology of producing Sodium salts humic acids with coal ", this invention provides a kind of technology of producing Sodium salts humic acids with coal, its technological process is that weathered coal is broken into the particle that granularity is 1.5mm, pro rata coal and water join in the reactor, add the nitric acid that is mixed with 1% solution again, fully reaction is 5-8 minute, begin heating, the sodium hydroxid of ratio preparation simultaneously liquid, join in the reactor, constantly stirring stopped heating after liquid boiling 10-15 minute, and the reaction times needs 1-2 hour, vapor pressure is 0.4Mpa during heating, reaction solution is extracted into earlier in the one-level settling tank precipitates, be extracted in the second-level settling pond precipitation after 1 hour 12-24 hour, when sedimentary liquid presents the black pasty state liquid of hanging the finger state it is pumped into preheating in the preheating pond, liquid is boiling and the time makes it flow to that oven dry is a finished product in the dryer again in the preheating pond, features simple and practical process of the present invention, free from environmental pollution, extraction cost is low, the extraction yield height can be promoted the use of.But because bigger at the Northwest's dust storm, the technical scheme of foregoing invention patent in process of production because settling tank is an open type, a large amount of dusts storm can fall into settling tank, influences quality product.When adopting natural sedimentation simultaneously, the floor space of settling tank is big, and sedimentation time is very long, causes the production process can not be continuous, thereby makes the production cycle long, and production efficiency is low.And it adopts drying with steam, and the equipment input is bigger, and production cost is higher, and can not continuous production.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, fully take into account the practical situation in west area, provide a kind of production unit configuration rationally, can realize the processing method of quantity-produced with coal production Sodium salts humic acids.
For realizing purpose of the present invention, the technical scheme that is adopted is: a kind of processing method of producing Sodium salts humic acids with coal, this method comprises the following steps:
A. the coal dust after will pulverizing screens by pneumatic separator;
B. the coal dust after will screening drops in the reactor and reacts;
C. reacted material enters the melt cinder separator, carries out solid-liquid and separates continuously;
D. isolated liquid is squeezed in the header tank with pump;
E. liquid is flowed into by header tank and concentrates;
F. the material after concentrating enters drying plant;
G. the material after the oven dry enters packing, is finished product.
Above-mentioned pneumatic separator is to utilize the material density difference to separate with the melt cinder separator.
Above-mentioned pneumatic separator is tornado dust collector.
Above-mentioned melt cinder separator is rotary solid-liquid separating machine.
A kind of drying plant of producing Sodium salts humic acids with coal, comprise oven dry rotating cylinder, oven dry groove, scraper plate and heating unit, scraper plate is installed in a side of oven dry rotating cylinder, and it is tangent with its cylindrical, it is characterized in that heating unit be fixedly mounted on oven dry in the rotating cylinder gas pipe line and be installed in burning shower nozzle on the gas pipe line, end at the oven dry rotating cylinder has the waste heat delivery port, in the lower end of above-mentioned scraper plate material conveyor is installed.
Characteristics of the present invention are: 1, can effectively the sand and dust in the coal be separated by cyclonic separator, for subsequent handling provides more purified raw material; 2, utilize the melt cinder continuous separator to replace traditional settling tank, can realize that quick melt cinder separates continuously, has improved production efficiency on the one hand.Preresearch estimates can be enhanced productivity 2-6 doubly; Can solve the problem that the big and northwest dust storm of settling tank floor space falls into quality product that settling tank causes decline on the other hand, improve quality product, production process can be carried out continuously; 3, owing to utilized the coal gas in the Northwest's coal deep-processing process to carry out heating, drying, product per ton can reduce oven dry cost 100-300 unit, has solved the environmental pollution that coal gas emptying burning is caused simultaneously; 4,, can the thermo-efficiency of whole drying course be improved, the production cost reduction waste heat of the oven dry rotating cylinder heat energy source when concentrating owing to have the waste heat delivery port at an end of oven dry rotating cylinder.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a process flow diagram of the present invention;
Fig. 2 is a drying plant structural representation of the present invention;
Fig. 3 is the A-A cut-away view of Fig. 2 of the present invention.
Embodiment
As shown in Figure 1, after will being used to produce coal process pulverizer 1 pulverizing of Sodium salts humic acids, enter in the pneumatic separator 2, utilize coal different with sandstone density, the sandstone in the coal are separated, pneumatic separator can adopt tornado dust collector.Coal after the selection by winnowing enters in the reactor 3 and reacts, and reactive mode adopts conventional at present mode to carry out.Reacted material is put into solid-liquid separating machine 4 carry out solid-liquid separation.Solid-liquid separating equipment can adopt rotary solid-liquid separating machine (production of Luonan environmental protection equipment factory) or other forms of solid-liquid separating equipment.Liquid after the separation is squeezed into it in header tank 6 by pump 5, provides material to concentrated cylinder 8 continuously by header tank 6, and material is concentrated.Material after concentrating enters in the oven dry groove, make the outer round surface of the material of oven dry in the groove by cylinder dryer 9 attached to drying roller, by scraper plate 10 the oven dry material on the cylinder dryer cylindrical is scraped, be finished product after weighing, pack by transfer roller 11 conveyings.
