Working method and principle：Before process units starts, cryogenic fluid pump 2 is first opened, cold air is transported to the He of raw material surge tank 3 In depropanization return tank of top of the tower 5, the raw material in raw material surge tank 3 is by being pumped into depropanizing tower 4 by heating separation third Alkane, raw material heat separate when caused mixed gas by depropanization return tank of top of the tower 5 when be cooled to liquid, then follow Ring carries out second to depropanizing tower 4 and separated, and so separates propane more thorough, the raw material after the completion of separation enters dehydration Thermal dehydration in device 6, the raw material after dehydration are entered in reactor 7, and sulfuric acid settler 8 is using the concentrated sulfuric acid injection as catalyst Into reactor 7, while iso-butane and butylene are added in reactor 7, reacted together, it is again that raw material is defeated after the completion of reaction It is sent in pickling expansion chamber 9 and carries out sulfur species and the lipid materials such as pickling removing sulfur dioxide, then after the completion of pickling Feedstock transportation neutralizes deacidification to carrying out alkalescence in alkali cleaning expansion chamber 10, after the completion of enter back into deisobutanizer 11 raw material existed The iso-butane that reaction is participated in reactor 7 spins off, and the iso-butane of abjection is back in reactor 7 again by pipeline joins again With reaction, iso-butane is formed a recycling, take off the raw material after iso-butane enter finally into de- normal butane tower 12 it is de- Normal butane is gone to form finished product isooctane, caused waste gas is discharged into waste acid pot 20, and the sour gas in waste acid pot 20 passes through It is pumped into pyrolysis furnace 24 to be cracked, the fuel as heat energy and air are transported to cracking by fuel tank 19 and blower fan 23 respectively Burnt in stove 24, the sour gas after cracking is respectively by dynamic wave 30, packed tower 31 and electrostatic precipitator 32 Sulfur dioxide gas is obtained after a series of washed reactions, then into being dried in drying tower 40, circulating slot 33 is made respectively For the aqueous medium feed trough of dynamic wave 30, packed tower 31 and electrostatic precipitator 32, the sulfur dioxide gas after being dried passes through First air-introduced machine 41, which enters, changes into sulfur trioxide in reforming unit, add water to be absorbed then into absorption tower 48, Sulfuric acid finished product is obtained, the waste gas that absorption tower 48 is discharged in absorption passes through to be discharged in the alkaline water progress of tail suction tower 49 with rear, nothing Any dusty gas discharge, energy-conserving and environment-protective, the sulfuric acid that absorption tower 48 is produced is pipelined in sulfuric acid settler 8 again to be made For the catalyst of iso-butane production.
Thermal cycle is that the air of inspiration is divided into two parts by blower fan 23 using the operation principle of device, and a part directly passes through Pipeline conveys into pyrolysis furnace 24, a part by after being heated in shunt conduit 25 to air preheater 26 again with another portion Point cold air can and, then one play and burnt in pyrolysis furnace 24, so add the air that burning is participated in pyrolysis furnace 24 Temperature, accelerate the drying of fuel, catch fire and combustion process, ensure stable burning in stove, play the work of improvement, overheavy firing With；The high-temperature flue gas of burning is reclaimed by waste heat boiler 27 in pyrolysis furnace 24, the air of heating by the 3rd air-introduced machine 28 again Return to the cold air for conveying blower fan 23 in the heat exchanger tube of air preheater 26 to heat, form recycling for heat energy.
The operation principle of waste water circulation utilized device be dynamic wave 30 and packed tower 31 caused by acid waste water pass through pipeline The orlop in spent acid pond 34 is discharged into, waste acid water by being pipelined to diluted acid again after two layers of the active precipitation of carbon slab 37 filtering In pond 35, and with electrostatic precipitator 32 caused by waste water mix together in the diluted acid pond 35, then after being mixed in diluted acid pond 35 Acid water circulating slot 33 be transported to by spent acid pump 36 be used as supplement water, and clean water is together as dynamic wave 30, filler Tower 31 and electrostatic precipitator 32 react water source.
The operation principle of waste gas recycling device can be being circulated as the acid waste water of the make-up water source of circulating slot 33 Acid fog is formed in groove 33, directly discharge can pollute to environment while be also to waste, and these sour gas can conduct Raw material is entered in drying tower 40 by exhaust fan 39 and steam pipe 42 and recycled, as the raw material for making sulfuric acid, drying tower 40 when the raw material to being exported from electrostatic precipitator 32 is thermally dried caused high-temp waste gas directly pass through air pump 43 are discharged into circulating slot 33, the acid waste water in heat cycles groove 33, accelerate its evaporation, and shower nozzle 44 can increase high-temp waste gas With the contact area of acid waste water, make evaporation effect more preferable, the acid in acid waste water in circulating slot 33 is preferably refined.
The operation principle of reforming unit is that the first air-introduced machine 41 is transported to the sulfur dioxide gas dried in drying tower 40 In converter 45, the temperature that the electric furnace 50 with temperature detect switch (TDS) makes to reach setting in converter 45 is opened, converter 45 starts Sulfur dioxide gas is converted, substantial amounts of heat energy can be produced during conversion, these heat energy pass through the second air-introduced machine 53 Store into a pair of heat exchangers 51, then heat energy is transported in converter 45 after a pair of heat exchangers 51, come as heating source Heated instead of the electric furnace 50 with temperature detect switch (TDS), then the electric furnace 50 with temperature detect switch (TDS) is closed automatically, plays energy-conservation Effect, because the single size of heat exchanger 51 is limited, often leading to the heat energy of its storage not enough can not reach higher temperature, Two longitudinal stacks of heat exchanger 51, and it is connected by air chamber, increases capacity, makes its internal temperature higher, then pass through needs With the transmission of Valve controlling hot blast, play with the reaction heat of itself to adjust the temperature in converter 45.
