Description
Technical field：
The present invention relates to a kind of L-type spent acid pyrolysis furnace.
Background technology：
In petroleum chemical industry, there are many process units all to use sulfuric acid, finally produce Waste Sulfuric Acid, such as alkyl
The devices such as change, acrylonitrile.These spent acid have generally comprised a large amount of organic impurities, and appearance is in the very big colloidal fluid of the viscosity of dark red
Body, property is unstable, often gives out strong stink.Industry is to be cracked by high temperature incineration, produce the flue gas containing SO2, then
Prepare concentrated sulfuric acid re-using.Spent acid high-temperature cracking furnace therein becomes spent acid cracking, regenerated key equipment.
Spent acid pyrolysis furnace industry generally use is horizontal pyrolysis furnace at present, usually with following features：
1. furnace body is broadly divided into three sections in the horizontal direction：Vaporization, mixing, conversion zone, furnace body length are generally up to 19m,
Furnace diameter then changes with processing amount；
2. mixing section generally sets multiple tracks deflected current wall (being often 6), the upper and lower baffling of flue gas is set to reach disturbance, mixing；
3. furnace body is designed using low wall temperature, between routine is 85-120 DEG C；
4. furnace body is designed by non-pressure vessel, furnace body sets rupture pressure disc.
Above-mentioned existing structure furnace body is huge, it is huge to take up an area, and burning effect is undesirable, and equipment can not avoid dew point corrosion, prevent
Quick-fried film is fragile etc., and there is an urgent need for improve.
The content of the invention：
The object of the present invention is to provide a kind of L-type spent acid pyrolysis furnace furnace structure, can on the basis of burning effect is ensured,
Significantly reduce equipment size, reduce floor space, prevent dew point corrosion, and ensure equipment life.
L-type spent acid pyrolysis furnace provided by the present invention, it is characterized in that, including vertical cylinder and horizontal cylinder, horizontal cylinder
One end and the bottom unicom of vertical component effect cylinder；Vertical cylinder top sets main burner and spent acid nozzle；In vertical cylinder
Portion sets flow-disturbing boss；The bottom of vertical cylinder sets auxiliary burner.
Multiple tracks tracery wall is set in the horizontal cylinder.
The tracery wall is 1-4 roads.
The main burner is arranged in center using single
Spent acid nozzle is then multiple, is arranged in the periphery of main burner.
Protective cover and hot-air interlayer are set outside vertical cylinder and horizontal cylinder.
The beneficial effects of the invention are as follows：
It is rational in infrastructure, it is easy to use, can be with the disturbance of efficient hardening flue gas.Ensure burning effect.Improve the use of equipment
Service life.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail：
Fig. 1 is schematic structural view of the invention；
In figure：1st, main burner；2nd, spent acid nozzle；3rd, boss is disturbed；4th, auxiliary burner；5th, tracery wall；6th, protective cover and
Air blanketing.
Specific embodiment：
As shown in Figure 1, L-type spent acid pyrolysis furnace, including vertical cylinder and horizontal cylinder, horizontal cylinder one end and vertical component effect cylinder
The bottom unicom of body；Vertical cylinder top sets main burner 1 and spent acid nozzle 2；The middle part of vertical cylinder 1 sets flow-disturbing convex
Platform 3；The bottom of vertical cylinder sets auxiliary burner 4.Multiple tracks tracery wall 5 is set in horizontal cylinder.Tracery wall 5 is 1-4 roads.Main combustion
The use of burner 1 is single, is arranged in center, and spent acid nozzle 2 is then multiple, is arranged in the periphery of main burner.
Protective cover and hot-air interlayer 6 are set outside vertical cylinder and horizontal cylinder.
Main burner 1 and spent acid nozzle 2 are located at the top of vertical cylinder.Preferably, main burner uses single, cloth
Put at center.Single burner helps to simplify operation, optimization flame profile.Spent acid nozzle 2 is preferably then 3, is arranged in master
The periphery of burner 1.After spent acid nozzle 2 increases, the adjustable range of spent acid treating capacity greatly increases, and atomizing effect can be in big model
Remain to be guaranteed in enclosing.
Downlink is mixed in the drop of vertical cylinder high temperature flue gas and atomization, while vaporizing.In vertical cylinder
Portion sets flow-disturbing boss 3, to strengthen contact of the drop with high-temperature flue gas.The space that vertical cylinder possesses abundance is used for drop vapour
Change, to prevent unboiled drips on refractory material, damage refractory liner.
In flue gas turning and the suitable position of horizontal cylinder, afterburning burner 4 is set, to ensure incineration temperature, and
The disturbance added to flue gas is provided.
Multiple tracks (1-4 roads, as needed) tracery wall 5 is provided with horizontal cylinder, to strengthen the disturbance of flue gas.Red-hot flower
Wall refractory material also provides extra ignite, it is ensured that the lasting burning of unburned component, lytic effect.
Preferably, furnace body is designed according to hot-wall structure, to ensure apparatus casing without dew point corrosion, it is ensured that equipment life.
Furnace body sets the air blanketing (separately declaring invention) with external thermal insulation, is improving outside wall temperature, is effectively preventing dew point corrosion
Meanwhile housing radiation loss can be reduced；
Preferably, horizontal cylinder and vertical cylinder are designed according to pressure resistant vessel, occur to remain in the case of sudden strain of a muscle is quick-fried in burner hearth
Ensure furnace body safety without leakage；
Preferably, separately set flame monitor, peephole, manhole, pressure gauge, thermometer on horizontal cylinder and vertical cylinder
Etc. other annexes.
Above-mentioned case study on implementation is only for clear example of the present invention, and is not the limit to embodiment of the present invention
It is fixed.To belonging to the spiritual changes and variations that derived from of the present invention still in protection scope of the present invention.
