Description
Technical field
The utility model relates to apparatus for producing ethyne field more particularly to a kind of cleaning dust cooling towers.
Background technique
The industries such as domestic PVC produce acetylene by two methods of wet process and dry method using calcium carbide at present.Calcium carbide is raw
Lime and carbon materials issue what biochemical reaction generated in calcium carbide furnace high-temperature, and main component is calcium carbide, wherein there are also few
CaO, CaS, Ca of amount2N2、Ca3P2、Ca2Si、Ca3As2Equal impurity.
Wet processing, which produces acetylene, can generate a large amount of wastewater slurry, and wastewater slurry throws away the acetylene of residual fraction after treatment
It is discharged, the acetylene of discharge causes the wasting of resources, while also generating security risk and causing environmental pollution.Therefore dry method work
Skill produces acetylene and produces acetylene instead of wet processing, and the generator that dry method produces acetylene technique is energy saving, water-saving result is significant, accounts for
Ground area is small, small investment, can there is the carbide slag slurries pollution problem generated during effective solution wet process acetylene production.
Drying acetylene reparation technology is by the way that water to be sprayed on calcium carbide in a manner of being atomized or spraying.Dry method system
The thick acetylene gas temperature taken is higher and carries a large amount of dust, and thick acetylene gas is passed through dedusting cooling tower (that is, water scrubber exchanges heat
Device) in be dusted and cooling processing.
The principle of calcium carbide hydrolysis: CaC2+2H2O=Ca(OH)2+C2H2, about 130KJ/mol energy is also generated in reaction.
Contain other impurities in calcium carbide, such as CaO, CaS, Ca2N2、Ca3P2、Ca2Si、Ca3As2, with water water can occur for impurity thereon
Solution reaction, reaction equation are as follows:
CaO+ H2O=Ca(OH)2+ H2S also generates about 63.6KJ/mol energy in reaction.
CaS+2 H2O=Ca(OH)2+ 2NH3；
Ca2N2+ 6H2The Ca(OH of O=3)2+2PH3；
Ca3P2+ 6H2O=3Ca(OH)2+NH3；
Ca2Si+4 H2O=2Ca(OH)2+SiH4；
Ca3As2+6 H2O=3Ca(OH)2+2AsH3；
Contain some impurity that cannot reflect with water of other impurities in calcium carbide.These impurity can be mixed into the second of generation
Thick acetylene gas is formed in alkynes gas.
Existing dedusting cooling tower inside (as shown in Figure 1) is divided into three layers by tower tray, shares two layers of filler in three layers of tower
An and heat exchanger, wherein the caliber of the tubulation of heat exchanger is generally 25mm.Dedusting cooling tower still will appear in actual production
Many problems, force halt production to be overhauled.By the research to process equipment and production technology, discovery causes stop production to overhaul equipment
The reason of mainly have the following: first is that, in equipment operation, the feelings of Severe blockage often occur heat exchangers in towers for heat exchanger tube
Condition needs frequent heat exchanging device tubulation to carry out disassembly cleaning dredging so that the resistance of system increases；Second is that heat exchanger tube
Cleaning dredging needs to stop production, and increases the production cycle of acetylene；Third is that frequent heat exchanging device tubulation disassembly cleaning, makes tubulation
The increase of dredging difficulty also be easy to cause the damage of tubulation so that production cost also increases considerably；Fourth is that the thick acetylene of discharge
It is un-cleared that device still contains part dust.It stops production and carries out the maintenance of equipment, so that the increase of equipment cost, maintenance difficulty increase, second
The cycle stretch-out of alkynes production, the service life of equipment reduce.
In view of this, it is necessary to dedusting cooling tower in the prior art be improved, to solve the above problems.
Summary of the invention
The purpose of this utility model is that a kind of cleaning dust cooling tower, which is filled out by increasing dedusting
