Description
Technical field
The present invention relates to producing carbon dioxide, specifically is technique for producing carbon dioxide and generating unit thereof that a kind of suitable coal mine explosion-proof, fire extinguishing and rescue and relief work are used.
Background technology
At present, the carbon-dioxide generator that use in the colliery all is made up of 2～3 head tanks, retort and auxiliary facilitys, and is bulky, and can not the operate continuously aerogenesis, air feed instability, level of automation are extremely low, operator are many, and the labour intensity height is unfavorable for carrying out the downhole safety operation.Therefore, can the operate continuously aerogenesis being purpose, the patent No. is that 98123697.9 Chinese patent discloses a kind of " equipment of continuously preparing carbon dioxide ", this equipment has been economized in 18 state-owned collieries of districts and cities and the local mine in 9 in China and has been applied, its fire extinguishing and datonation-inhibition particular significant effect, and users' approval and favorable comment have been won with the performance of brilliance, but reflect according to the user, there is following point in this product, awaits improving: 1, existing installation is made up of two producers of same model, wherein a job, another is got the raw materials ready, the cycle operation of two chaptrels stream is with this method continuously preparing carbon dioxide, still, actual aerogenesis technological process is discontinuous, but be interrupted, cause aerogenesis flow and pressure transient, influence gas making efficiency; 2, a set of equipment has two producers, and two pressurized vessels all are housed on each producer, total four pressurized vessels that differ in size, and two material-storing box and feed device in addition, equipment volume is huge, is unfavorable for transportation under the coal mine, installs, uses; 3, equipment gas-made technology flow process is: four procedures such as charging, system gas, exhaust, blowdown, and each procedure must carry out respectively sequentially, the gas-made technology complexity, Technology falls behind; 4, the gas-made technology process of equipment realizes by manual operation entirely, so the accessory switch of equipment and valve frequent starting cause breakdown rate and spoilage to increase, and labour intensity are big.
Summary of the invention
The present invention provides a kind of technique for producing carbon dioxide for each the operation proceed step by step that solves existing gas-made technology, problem backward in technique.
The present invention adopts following technical scheme to realize: technique for producing carbon dioxide comprises the steps:
1, sulfuric acid and ammonium bicarbonate soln are added retort (being pressurized vessel) internal reaction simultaneously after feeding unit mixes, generate carbon dioxide, finish charging, system gas operation;
2, when carry out step 1, open the outside exhaust of vent valve, by observing the under meter on the vapor pipe, by Flow-rate adjustment valve regulation charging: the flow of sulfuric acid and ammonium bicarbonate soln, deairing step is finished in the outside exhaust of gas production rate of pressing actual needs;
3, when carrying out step 1,2, be installed on liquidometer on the retort by observation, the wash water valve aperture of conditioned reaction pot bottom, the waste liquid height in the control retort the retort height 1/2nd to 1/4th between, the blowdown operation is finished in outwards blowdown continuously.
Technology of the present invention is carried out mixed gas simultaneously in charging, and in system gas, carry out exhaust, blowdown, to feed, make four procedure concurrent jobs such as gas, exhaust, blowdown, therefore, only carry out the carbon dioxide preparation continuously with a pressurized vessel, can satisfy actual in the middle of to the demand of carbon dioxide consumption, and do not need the work that hockets of the retort of two even greater amt, simplify the device structure of realizing this technology.
In addition, the present invention solves problems such as existing carbon dioxide preparation apparatus volume is big, system gas is discontinuous simultaneously in order to realize above-mentioned gas-made technology, and a kind of carbonic acid gas generating unit is provided.
Described carbonic acid gas generating unit, comprise retort (being pressurized vessel), the retort top is provided with feeding unit, safety valve, tensimeter and vapor pipe, vapor pipe is provided with vent valve, the retort bottom is provided with wash water valve, described feeding unit comprise stretch in the retort, be fixed in pipe and charging outer tube in the charging together, have opening for feed on the charging outer tube wall, the opening for feed in the charging on pipe top and the charging outer tube is respectively equipped with flow control valve; The tube wall of pipe bottom and the pipe end, have the charging spray apertures in the charging, in charging outer tube and the charging between the pipe, with charging in manage the charging spray apertures over against locating to be provided with impeller inducer;
