Description
Technical field
The present invention relates to the sodium formiate production technical field, be specifically related to the preparation method of a kind of sodium formiate production with virgin gas.
Background technology
At the sodium formiate production field, when preparing sodium formiate production with virgin gas CO, preparation method commonly used does, is raw material with the coke at present, and oxygen and carbonic acid gas are vaporized chemical, adopts fixed bed partially oxidation reduction method continuous gasification system CO gas, and its principal reaction is following:
C+O
2=CO
2+394.5KJ/mol （1）
C+CO
2=2CO-168.5KJ/mol （2）
C+1/2O
2=CO+112.9KJ/mol （3）。
Reaction is mainly undertaken by formula (1) and formula (2), and reaction (1) and reaction (3) are oxidizing reaction, are strong exothermic process, and reaction (2) is a reduction reaction, is thermo-negative reaction.
For a long time; People think with coal to be that feedstock production virgin gas CO is the important symbol that Chinese sodium formiate industry lags behind world level always; Therefore at late 1980s, the beginning of the nineties; The whole nation has started a dant and has changed oily tide, proves that afterwards this technological transformation falls flat, and has caused great financial loss.Through analysing in depth, a lot of experts think that the sodium formiate industry of China will possess the competitive power of world market; Also should walk with coal is the way of raw material; Because the hard coal price of China is low, be about 1/2nd of European hard coal price, production cost is low; The sodium formiate product price that makes is low, has the bigger market competitiveness.Through the development of decades, the total scale of China's sodium formiate industry has reached the first in the world at present, and the scale of sodium formiate production equipment also constantly enlarges, and the sodium formiate industry has obtained tremendous development.But the under-supply problem of feed coal also more and more highlights, and becomes one of problem demanding prompt solution that the sodium formiate industry faces.
Rich coal resources in China; The price of labour power is cheap relatively, and the market value of coal is lower than the world market for a long time, and the sodium formiate device that with coal is raw material is the basis of China's sodium formiate industry; At present accounted for more than 65% of sodium formiate production, the market share also will further enlarge from now on.The lump coal that China is used for sodium formiate production mainly originates from ground such as Jincheng, Shanxi, Yangquan, Guizhou; Year, consumption was up to more than the 40000kt; Along with the high speed development of sodium formiate industry, the under-supply problem of feed coal becomes increasingly conspicuous, and the feed coal price goes up significantly; Cause the sodium formiate cost to raise, promoted the rise of sodium formiate price.
In recent years, the oxygen-enriched continuous gasification technology occurs, can realize the continuous gasification of lump coal, moulded coal, brought revolutionary progress for sodium formiate industry.Because adopt continuous oxygen-rich gasification technology, the Gas-making Furnace gas deliverability can improve 1～1.5 times, make the follow-up system of sodium formiate possess the precondition that transformation expands the scale of production, with welcoming the once big development of sodium formiate industry.Existing Gas-making Furnace is to be that raw material is produced virgin gas with the coal mostly, and the method for producing virgin gas at present mainly contains: fixed intermittent layer gasification method, immovable bed continuous gasification method, fluidized bed evaporating method, airflow layer evaporating method etc., and there are a lot of drawbacks in above method; Complex process, operator are many, labour intensity is big, and are high to the requirement of starting material coal; Production capacity is low, and the feed coal burning is not thorough, and the lime-ash remaining carbon is high; And on to blow carry-over many, environmental pollution is very big.
All measures that help country, the research and development of enterprise production systems technology and transform such as present China is advocating energetically and saving energy and reduce the cost, environmental protection; Be Sustainable development and social enviroment protection creation advantageous conditions; Therefore how realizing energy-conservation, the cleaner production of sodium formiate production field, is major issue anxious to be solved.
Summary of the invention
The purpose of this invention is to provide the preparation method of a kind of sodium formiate production with virgin gas.
In order to realize above purpose, the technical scheme that the present invention adopted is: a kind of sodium formiate production is with the preparation method of virgin gas, and this preparation method is: will be by oxygen-rich air and CO
2The continuous fuel bed that feeds 800～1200 ℃ of the gas mixture of forming reacts, and makes sodium formiate production and uses virgin gas.
Further, said oxygen-rich air is the oxygen volume percent content greater than 90% air.
In the said gas mixture, oxygen-rich air and CO
2Volume ratio be: oxygen-rich air volume: CO

The said sodium formiate production that makes is CO gas with the staple of virgin gas, and wherein the concentration of volume percent of CO is 60～75%.CO and NaOH reaction make the sodium formiate product, and reaction formula is:
CO+NaOH=HCOONa。
Sodium formiate production specifically may further comprise the steps with the preparation method of virgin gas:
(1) be in the coke ball or blue charcoal adding vapourizing furnace of 20～65mm, with particle diameter by oxygen-rich air and CO
2The gas mixture of forming feeds in the said vapourizing furnace continuously, and the coke fuel bed or the blue charcoal fuel bed of said gas mixture and 800～1200 ℃ react, and make the thick furnace gas of vapourizing furnace;
(2) the thick furnace gas of said vapourizing furnace is through the tornado dust collector dedusting, gets into waste heat boiler afterwards and reclaims heat, and then get into scrubber tower processings of lowering the temperature, and temperature is reduced to below 45 ℃, carries out desulfurization then and handles, and the gas after the desulfurization processing compresses again;
(3) a part of gas after the compression is sent to and is carried out the decarburization purification processes, and another part gas carries out conversion process, and the CO in the gas is converted into CO
2And then carry hydrogen and handle, returning said vapourizing furnace use through carrying the gas that obtains after hydrogen is handled, the hydrogen of extraction is used for PVC production; The gas that the decarburization purification processes obtains is sodium formiate production and uses virgin gas, and the dioxide gas that the decarburization purification obtains returns said vapourizing furnace and uses.
Sodium formiate production provided by the invention is with the preparation method of virgin gas; Promote system gas gasification efficient, and reduced the consumption of feed coal, reached purpose of energy saving; Simultaneously can reduce working strength of workers; Successfully remedied the realistic situation that the sodium formiate industry technology falls behind, had important leading and exemplary role, be with a wide range of applications.
