Waste Sulfuric Acid, the acid of this Waste Sulfuric Acid is dense relatively low, containing organic/inorganic substance and the inorganic salt of high concentration, it is extremely difficult to process.
The processing method of Waste Sulfuric Acid mainly has following several at present: 1. alkali neutralisation, allows sulphuric acid carry out with various inorganic bases
Neutralize reaction, extracting sulfuric acid ammonium, magnesium sulfate, calcium sulfate etc..2. concentrate after imurity-removal, by adsorbing, filter, aoxidize, distilling,
The mode such as air stripping, extraction removes the organic and inorganic impurity in Waste Sulfuric Acid, is then concentrated to give the dilute sulfuric acid after remove impurity
Industrial concentrated sulphuric acid.3. reduction decomposition method, is sulfur dioxide with hydro carbons by Waste Sulfuric Acid reduction decomposition, processes the most further.4.
High-temperature cracking method, reclaims sulfur dioxide, sulfur trioxide or sulfur by Waste Sulfuric Acid pyrolytic.All there is technique in these processing methods
Complicated, processing cost is high, product quality is uneven, process the problem such as the most thorough.
Compared with above processing method, the method for Waste Sulfuric Acid burning Sulphuric acid can fundamentally solve the process of Waste Sulfuric Acid
The advantages such as problem, has processing cost low, and product yield is high, good product quality, production process environmental protection, and by-product is a large amount of
Steam, other need the equipment of steam to can be used to generating or supply plant area, have good environmental benefit and economic benefit.
Summary of the invention
Owing to traditional Waste Sulfuric Acid incinerator cannot process high saliferous Waste Sulfuric Acid, the present invention be directed to above-mentioned present situation, and carry
A kind of incinerator for processing high saliferous Waste Sulfuric Acid gone out, the high saliferous Waste Sulfuric Acid of suitable treatment various chemical plant installations by-product.
The inorganic salt that the Waste Sulfuric Acid that general incinerator processes contains high concentration, the kind of inorganic salt includes the sodium of the first and second main groups
Salt, potassium salt, magnesium salt, calcium salt and transition metal salt.By high temperature incineration, Waste Sulfuric Acid cracking in incinerator contains dioxy
Changing the flue gas of sulfur, subsequently into follow-up acid making system preparing finished articles sulphuric acid, Organic substance generates carbon dioxide and water, contains in Waste Sulfuric Acid
It is pooled to fused salt guiding gutter after some inorganic salts are melted, is then discharged by the salt discharge hole bottom incinerator.
The present invention is achieved like this: for processing the incinerator of high saliferous Waste Sulfuric Acid, it is characterised in that: incinerator is
Horizontal type structure, by outer and in include external thermal insulation, housing, insulating, fire-resistant acidproof resistance to salt deposit, housing includes cylinder, end
Plate and bearing；Burner end plate is provided with spent sulfuric acid spray gun, main burner, hand hole；Cylinder be provided with explosionproof hole, flame detector,
Visor, auxiliary burner, point for measuring temperature, pressure tap, manhole, baker steam vent；Be arranged alternately inside burner hearth perforate firebreak and under
Perforate firebreak；Burner hearth bottom is provided with the fused salt guiding gutter at certain inclination angle, and arranges salt discharge hole in its minimum point；Furnace gas export
It is arranged on incinerator afterbody；Described fire-resistant acidproof resistance to salt deposit uses prefabricated fire-resistant acidproof salt tolerant brick masonry, described fire-resistant resistance to
The resistance to block salt of acid is made for adding metal-oxide in corundum.
Usually, described corundum includes electro-corundum, alundum, and the metal-oxide wherein added includes ZrO2、
Cr2O3、TiO2。
Described burner end plate is provided with at least one spent acid spray gun, at least one main burner, a hand hole, and stove transom piece sets
There is furnace gas export；Spent acid spray gun use mechanical atomization or compressed air atomization form, the material of spent acid spray gun be carborundum,
Rustless steel or other heat-resisting salt tolerant steel alloys；Burner material is rustless steel.
Described external thermal insulation uses composition silicate fiber felt, ceramic fiber blanket or rock wool heat-preservation material.
The material of described housing is carbon steel, rustless steel or other steel alloys；Cylinder is externally provided with several stiffening ring, strengthens ring
To soldering stainless steel plate as rain cover；It is welded with hexsteel or anchor studs structure inside cylinder, is used for fixing insulating,
The material of hexsteel or anchor studs is carbon steel, rustless steel or other heat-resisting alloy steels, and the form of anchor studs includes Y type, V-type, S
Type, Ω type；Being provided with anticorrosive heat insulating layer inside cylinder, anticorrosive heat insulating layer is some all over graphite waterglass anticorrosive coat for first brushing, and then sticks
Patch asbestos board or ceramic beaverboard thermal insulation layer, or the coating of brush high temperature-resistant acid-resistant erosion or binding agent.
Before and after described incinerator, the top of cavity is respectively provided with 1 explosionproof hole, and the side of cylinder is provided with at least 1 fire defector
Device, at least 1 visor, at least 1 auxiliary burner, at least 1 manhole, at least 2 points for measuring temperature of cylinder top setting, at least 1
Pressure tap, at least 2 baker steam vents, cylinder body bottom arranges at least 1 salt discharge hole.
Described cylinder is at least 4 by seat supports, the number of bearing, and incinerator is placed on some groups of bearing rollers, often
Group bearing roller is made up of at least 2 round steel；The material of round steel is carbon steel, rustless steel or other steel alloys.
Described insulating horizontal and vertical on every 1～3m, one expansion joint is set；Between insulating, with
And the expansion joint fissure of displacement layout between insulating and fire-resistant acidproof resistance to salt deposit, fissure of displacement distance is more than 100mm；Insulating
Material is: aluminate or phosphate make bonding agent, adds aggregate and makes.
The middle part of described incinerator arranges at least 2 road firebreaks, the material of firebreak brick and fire-resistant acidproof resistance to salt deposit phase
