Description
Technical Field
The invention relates to a gasification furnace system for coal chemical production, in particular to a three-waste mixed combustion gasification furnace system.
Background
The energy structure of our country is rich coal, lack of oil and less gas, and from this situation, the coal chemical industry accounts for a large percentage in national economy. The coal gasification technology is always the technical tap and the core of the coal chemical production process, and can convert coal into synthesis gas mainly comprising carbon monoxide and hydrogen, so that the synthesis gas can be further used for synthesizing downstream chemicals or used as fuel, and the efficient and clean utilization of the coal is realized. The advancement of the gasification technology directly determines the advancement and the final operation cost of the coal chemical plant, and also directly determines the market competitiveness of enterprises. The gasification technology of coal is generally realized by a gasification furnace system, and core equipment gasification furnaces in the gasification furnace system can be divided into a fixed bed gasification furnace, a fluidized bed gasification furnace and a fluidized bed gasification furnace according to the contact mode of gas-solid raw materials. The entrained-flow bed gasification furnace has high carbon conversion rate and high productivity, is most widely applied at present, and is divided into two gasification processes of dry coal powder feeding gasification and coal water slurry feeding gasification. The method comprises the following steps of discharging crude gas generated by a gasification furnace into a gas washing tower, sequentially passing the gas treated by the gas washing tower through a CO conversion device (carbon monoxide conversion device), a low-temperature methanol washing device, a liquid nitrogen washing device and the like to generate hydrogen, feeding wastewater generated in the gas washing process of the gas washing tower into a black water flash evaporation settling device, and discharging fine slag.
At present, problems which cannot be solved exist in both dry pulverized coal feeding gasification and coal water slurry feeding gasification, and particularly the problems that pollutants (namely three wastes, namely waste residues, waste liquid and waste gases) generated in the production process are not thoroughly treated and the like are urgently solved.
The waste residues in the coal chemical production process are mainly fine residues (filter cakes are usually prepared by filter pressing equipment) generated in a black water treatment device, the heat value is about 3000Kcal/kg, the water content is generally 40-60%, and the filter cake output of a single set of gasification furnace system per day is about 260 tons by taking a gasification furnace which puts coal in per day of 2600 tons as an example. The current general treatment mode is as follows: the building material is used as auxiliary material for making building material and is fed into fluidized bed steam boiler for combustion. The former has poor application prospect and low market demand due to high carbon content of filter cakes; the latter is not efficient and has a large negative impact on boiler equipment. Therefore, the filter cake (fine slag) generated from the gasification furnace is difficult to handle. In addition, the storage of the waste residues not only occupies a large amount of land, but also causes serious pollution to soil and water bodies due to dust and percolate, so that the treatment and utilization of the coal gasification waste residues are social problems which are not slow, and the application and popularization of the coal gasification technology are restricted. For a gasification furnace of 2600 tons of coal fed per day, about 100 to 200 tons (dry basis) of fine slag are generated per day, the residual carbon is generally 20 to 40 percent, and if the residual carbon can be reused, the coal consumption can be effectively reduced by 5 percent.
The waste liquid in the coal chemical industry production process (such as the process of producing methanol, ethanol, glycol, olefin and synthetic ammonia and the process of washing a low-temperature methanol washing device) mainly comprises organic waste liquid such as methanol, ethanol, glycol, olefin and the like, particularly organic waste liquid containing sulfur, and is very difficult to dispose; further, for example, oil which is replaced during operation of the apparatus is difficult to handle.
The waste gas in the coal chemical industry production process comprises the deoxygenated vent gas generated in a black water flash evaporation settling device, and in general, H of the waste gas2、CO、H2S, COS contents (V%) are respectively 5.52%, 11.19%, 4.21% and 1.80%, and for 2600 tons of gasification furnace with coal charged per day, 0.345Kg of H is added per hour2S and 0.262Kg of COS are directly discharged into the atmosphere after torch combustion, and 7600Nm is available every year3The above effective gas (H)2CO) is wasted. The waste gas also comprises stripping gas generated when ammonia-containing washing water in the CO conversion device is stripped, and the stripping gas isAcid gases, in general, where H is responsible2S, COS content is low (0.61%, V%), it is difficult to send sulfur recovery device to dispose, and increase the investment of sulfur recovery device, it is generally sent to the boiler to burn. But H in the acid gas2The CO content (V%) is about 3.19%, and 32 ten thousand Nm/year for a gasification furnace with coal input of 2600 tons3The above effective gas (H)2CO) is wasted. The waste gas also comprises desorption gas (commonly called fuel gas) generated in the process of preparing process gas in the liquid nitrogen refining process and desorption gas generated by a pressure swing adsorption device after low-temperature methanol washing, wherein H is contained in the desorption gas2The effective components such as CO are still high, taking the synthetic ammonia (60 ten thousand tons of ammonia per year, 2600 tons of coal put in a day) prepared by Jinhua furnace 3.0 as an example, the desorption gas generally contains H2、CO、CH4The contents (V%) of (A) are 4.3%, 41.5%, 9.3%, respectively, and the so-called "exhaust gas" is sent to the boiler for combustion, resulting in about 2000 ten thousand Nm3Annual H2And green energy such as CO is degraded. The Jinhua furnace 3.0 gasification process is used for producing 60 ten thousand tons of ammonia per year, if the H in the two gases is used2CO is recycled, and the yield of synthetic ammonia can be increased by approximately 10000 tons every year; CH in exhaust gas4The recycling can increase the yield of the synthetic ammonia by 7300 more tons each year. The productive synthetic ammonia can effectively reduce the coal consumption by 2.8 percent.
Only after the waste gas of the production system and the waste residue of the gasification system are treated cooperatively, the consumption of raw material coal can be reduced by 5% + 2.8% + 7.8%, compared with the integral consumption of domestic gasification raw material coal, the cost of enterprises can be greatly saved, the environmental protection pressure can be reduced, and the environmental protection benefit is created.

The lower part of the combustion chamber 15 is provided with a combustion chamber slag outlet 16, and a flash evaporation gas chilling ring 30 is arranged below the combustion chamber slag outlet 16. Chilling medium nozzles are uniformly distributed on the inner side of the ring body of the flash gas chilling ring 30 and used for spraying gas for chilling the gasification product passing through the flash gas chilling ring 30; the chilling flash gas inlet 17 of the flash gas chilling ring 30 is connected with a flash gas compressor, and the flash gas compressor is connected with flash gas discharge ports of the low-temperature methanol washing device and the liquid nitrogen washing device and is used for chilling gas in the combustion chamber 15 through flash gas. The chilling ring is a conventional structure of the gasification furnace, and flash steam is adopted as a chilling medium in the invention.
The waste heat recoverer 40 is cylindrical, a heat exchange medium channel is arranged in the side wall of the waste heat recoverer, a heat exchange surface is formed on the inner cylinder wall, and the heat exchange surface is sprayed with a graphene material which is resistant to high temperature and high pressure and prevents ash and slag from adhering and is used for chilling gas in the combustion chamber 15 and recovering waste heat. The three-waste mixed combustion gasification furnace system further comprises a vibration excitation device which is a pneumatic vibration excitation device, the pneumatic vibration excitation device is arranged on a pneumatic vibration excitation interface 18 on the side wall of the waste heat recoverer 40 and comprises a vibration beating head, and the vibration beating head stretches and retracts in a reciprocating mode along the radial direction of the gasification furnace to beat the waste heat recoverer 40 to generate vibration and is used for vibrating ash and slag adhered to the inner wall of the waste heat recoverer 40. The pneumatic excitation device is provided in a plurality of places around the waste heat recoverer 40. The waste heat recoverer 40 is a heat exchanger, which is a conventional structure of a gasification furnace, and will not be described in detail in the present invention.
The lower end of the waste heat recoverer 40 is connected with the descending channel 50, and the lower end of the descending channel 50 extends into chilling water to realize physical chilling of the gasification product. Of course, the raw gas outlet 13 is located above the level of the quench water.
When the three-waste mixed combustion gasification furnace system runs, the coal water slurry sprayed out by the first type burner is combusted in the combustion chamber 15 to provide heat for gasification reaction and realize gasification of the coal water slurry, so as to generate high-temperature synthesis gas; in addition, the slag slurry is sprayed into the combustion chamber 15 through a second type of burner nozzle and is sheared and atomized by waste gas, and carbon and H in the slag slurry2O、CO2Reacting under the action of heat provided by the first type of burner to generate H2CO, reaction formula: c + H2O＝CO+H2、C+CO22 CO. And, CH in the exhaust gas (stripping gas)4And H2O also reacts to form H2CO, reaction formula: CH (CH)4+H2O＝CO+3H2。
The reaction processes corresponding to the reaction formulas all need to absorb heat, so that the temperature of the high-temperature synthesis gas can be reduced, and the viscosity of ash slag of the ash slag can be simultaneously reduced, so that the processes of atomizing, burning and gasifying the slag slurry by using the second type of burner are simultaneously a chemical reaction chilling process. H-containing gas produced by the low temperature methanol scrubbing, liquid nitrogen scrubbing apparatus as the high temperature synthesis gas and ash pass downwardly through the furnace slag outlet 162After being pressurized by a flash gas compressor, the higher flash gas enters the gasification furnace through a flash gas chilling ring 30, and cools the high-temperature synthetic gas discharged from a slag hole 16 of the combustion chamber and entering a waste heat recoverer 40, so that the viscosity of ash slag carried by the high-temperature synthetic gas is reduced, and the process of physically chilling the high-temperature synthetic gas and the ash slag by using the flash gas is realized. In the present example, the molar ratio of each component in the flash vapor discharged from the flash vapor compressor was H2：35.31％、CO：1.19％、CO2：61.65％、N2：1.27％、AR：0.14％、H2S：0.05％、CH4: 0.35 percent. The synthesis gas and the carried ash are further downward and can pass through a waste heat recoverer 40 for heat exchange chilling, physical chilling of ash water and humidification in sequence. Finally, the synthesis gas is discharged through a raw gas outlet 13, and the raw slag with low carbon content is discharged from a raw slag outlet 14 at the bottom of the gasification furnace.
The ash has different degrees of viscosity at different temperatures, and during normal production, the ash carried by the synthesis gas still has good fluidity when leaving the slag outlet 16 of the combustion chamber, so that the slag outlet 16 of the combustion chamber is not blocked. The viscosity of the slag outlet 16 from the combustion chamber is typically controlled to be between 5 and 25pa.s, depending on the viscosity-temperature characteristic of the ash. If the temperature is too high, slag can not be adhered to the inner water-cooled wall or the refractory bricks of the gasification furnace, and the safety of internal parts of the gasification furnace is directly threatened; conversely, if the temperature is too low, ash tends to accumulate and block the combustor slag outlet 16. Meanwhile, a higher oxygen-coal ratio is required to ensure the gasification efficiency in normal production, the reaction temperature is increased as much as possible and is generally 100 ℃ higher than the ash melting point, and the ash fluidity is realized at the momentPreferably, the high-temperature gas (above 1350 ℃) contains about 20 percent of H2O and about 19% CO2. The invention uses the endothermic reaction process to reduce the temperature of the ash slag carried in the high-temperature synthesis gas to the temperature corresponding to the viscosity of 25Pa.s in a chemical chilling mode, so that the ash slag leaves the slag outlet 16 of the combustion chamber and enters the waste heat recoverer 40. When a large amount of high-temperature ash continuously enters the waste heat recoverer 40 through the combustion chamber slag outlet 16, although the temperature is gradually reduced, the viscosity is still high, and the ash may adhere to the heat exchange pipe, thereby affecting the heat exchange effect. The invention uses the above-mentioned H-containing gas after the syngas exits the combustor slag outlet 16 and before it enters the waste heat recovery 402The flash steam with higher temperature cools the ash to lower the ash temperature to below the ash melting point, and the ash can quickly form a vitreous body to lose viscosity.
Taking the coal type from Hangzhou Bay in Shaanxi as an example, the ash viscosity-temperature characteristic curve shows that the corresponding temperatures are 1383 ℃ and 1270 ℃ respectively when the viscosity is 5 and 25Pa.s, and are both higher than the flowing temperature (1204 ℃). The invention uses the second type burner to spray carbon in the slag slurry and CH in the waste gas4Etc. are reacted with H2O、CO2The temperature of the ash before leaving the combustion chamber 15 of the gasification furnace is reduced to be higher than the temperature (namely 1270 ℃) corresponding to the viscosity of 25Pa.s, so that the ash smoothly leaves the slag outlet 16 of the combustion chamber; after leaving the slag outlet, the waste heat recovery device 40 uses the above-mentioned H2The high flash steam quenches the waste heat recovery device, so that the temperature of high-temperature synthesis gas and ash slag can be reduced to be lower than the ash melting point (1204 ℃), the ash slag carried in the synthesis gas loses viscosity, the treatment of waste liquid, waste gas and waste slag generated in the coal chemical production process is realized, and the operation period of the waste heat recovery device 40 and the gasification furnace can be effectively prolonged.
