Abstract
The present invention provides a kind of coal gas production method, belongs to Gas Production technical field, the coal gas production method comprises the following steps：Nitrogen and oxygen rich gas are produced using nitrogen making machine；Coal dust, vapor, air and the oxygen rich gas of nitrogen making machine production, the reaction generation coal gas under high temperature and high pressure environment are added to powder coal gasification furnace；The coal gas of fine coal gasification burner production obtains product coal gas after cyclone separator, heat exchanger, sack cleaner, desulphurization plant；The nitrogen of nitrogen making machine production is used for the injection of bag-type dust removal system.The present invention adds fine coal gasification burner by the oxygen rich gas for generating nitrogen making machine, by the burning of oxygen-enriched aggravation powder coal gasification furnace, relative to conventional production methods, it is possible to increase the calorific value of coal gas, and then make the conveying cost of coal gas that is produced by this method lower, and improve transfer efficiency.
Description
Technical field
The invention belongs to Gas Production technical field, and in particular to a kind of coal gas production method.
Background technology
When gas station produces coal gas, in order to carry out dedusting, it is necessary to using sack cleaner, due to sack cleaner dedusting
Shi Huiyou coal particles are attached on cloth bag, influence efficiency of dust collection, it is therefore desirable to cloth bag is sprayed using nitrogen making machine production nitrogen
Blow, oxygen rich gas would generally be generated after nitrogen making machine production nitrogen, this portion gas would generally be released in air.
The content of the invention
In order to using the oxygen rich gas of nitrogen making machine production, avoid the wasting of resources, the invention provides a kind of Gas Production side
Method, comprise the following steps：
Nitrogen and oxygen rich gas are produced using nitrogen making machine；
Coal dust, vapor, air and the oxygen rich gas of nitrogen making machine production are added to powder coal gasification furnace, in HTHP ring
Reaction generation coal gas under border；
The coal gas of fine coal gasification burner production must produce after cyclone separator, heat exchanger, sack cleaner, desulphurization plant
Product coal gas；
The nitrogen of nitrogen making machine production is used for the injection of bag-type dust removal system.
The invention has the advantages that：
The present invention adds fine coal gasification burner by the oxygen rich gas for generating nitrogen making machine, passes through oxygen-enriched aggravation powder coal gasification furnace
Burning, relative to conventional production methods, it is possible to increase the calorific value of coal gas, and then the coal gas for making to be produced by this method is defeated
Send cost lower, and improve transfer efficiency.
Brief description of the drawings
Fig. 1 is a kind of schematic flow sheet of better embodiment of the present invention.
Main element symbol description
Following embodiment will combine above-mentioned accompanying drawing and further illustrate the present invention.
Embodiment
The following examples can help those skilled in the art that the present invention is more fully understood, but cannot be with any
Mode limits the present invention.
Such as Fig. 1, this is to realize the flow chart of production system constructed by a preferred embodiment of the present invention, and the system includes
Nitrogen making machine 1, powder coal gasification furnace 2, cyclone separator 3, one-level heat exchanger 4, two-stage heat exchanger 5, sack cleaner 6, three-level
Heat exchanger 7, desulphurization plant 8.
Nitrogen making machine 1 produces nitrogen and oxygen rich gas, and nitrogen is sent into sack cleaner 6 and carries out cloth bag injection, and oxygen rich gas leads to
Cross air blower and be sent into fine coal gasification burner 2；
The oxygen rich gas of coal dust, vapor, air and nitrogen making machine production is sent into fine coal gasification burner to be burnt, in height
Coal gas is generated in the environment of warm high pressure；Preferably, according to the oxygen rich gas growing amount of nitrogen making machine, quantity of steam and coal-supplying amount are adjusted,
The temperature for ensureing powder coal gasification furnace simultaneously can make the production efficiency of powder coal gasification furnace reach maximum at 1200 DEG C or so.
Fine coal gasification burner production coal gas in order by cyclone separator, one-level heat exchanger 4, two-stage heat exchanger 5,
Product coal gas is obtained after sack cleaner, three-stage heat exchanger, desulphurization plant；
Coal gas from cyclone separator come out after be 980 DEG C or so, after one-level heat exchanger and two-stage heat exchanger
Temperature is 220 DEG C, is then fed into after sack cleaner dedusting that temperature is re-fed into after being reduced to 45 DEG C after three-stage heat exchanger
Desulfurization device carries out sulphur removal, and product coal gas is obtained after sulphur removal.
Product coal gas is sent to holding vessel or with gas point by pressurized equipment.
By actual test, the calorific value of gas produced using this method is higher, and then makes the coal produced by this method
The conveying cost of gas is lower, and improves transfer efficiency.
