Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the carbide slag slurries acetylene recovery system of the utility model, including slurry surge tank 1 and slurry buffer
The desorption tower 3 that the slurry overflow tank 9 that tank 1 is connected to is connected to by Pulp pump 2, desorption tower 3 are respectively communicated with 4 He of evaporative condenser
Negative-pressure water-sealing tank 10, evaporative condenser 4 are respectively communicated with water recirculator 5 and condensate drum 11, condensate drum 11 and acetylene
Generating device connection；The connection freezing water cooler 6 of water recirculator 5, freezing water cooler 6 are connected to acetylene by vacuum pump 7
Surge tank 8, acetylene surge tank 8 are connected to oxygen content analyzer 12.
The principles of the present invention are that the carbide slag slurries overflowed from acetylene generating system enter slag by closed conduit
Surge tank 1 is starched, it is in slurry surge tank that a large amount of silicon iron contained in carbide slag slurries, carbon slag and bulk impurity solid particle etc. is real
Now efficiently separate；Carbide slag slurries after separation are sent into desorption tower 3, the silicon iron filtered down, carbon slag and bulk impurity by Pulp pump 2
Slurry surge tank 1 is discharged by slag-drip opening in equal solid particles, finally plays the effect of protection Pulp pump and desorption tower stable operation.
Meanwhile design has a steam-stirring function in slurry surge tank 1, steam is divided into two outlets after entering slurry surge tank, export away from
From tank bottom 200mm.The turbulence that carbide slag slurries can both be increased in this way makes by Ca (OH)2The life calcium carbide of cladding is sufficiently contacted with water,
Release acetylene gas, can also play prevent carbide slag from depositing in slurry surge tank tank, fouling the problem of.In addition, slurry is slow
It rushes pot bottom and devises slurry backflow functionality, be conducive to silicon iron, carbon slag and bulk impurity and be deposited on slag-drip opening, and then exclude slurry
Surge tank, and the problem of carbide slag slurries deposit can be effectively reduced.
Carbide slag slurries are sent into desorption tower 3 by Pulp pump 2, under vacuum conditions, acetylene qi exhaustion will be contained in carbide slag slurries
It sucks out, after vapor and acetylene come out from tower top, into the evaporative condenser 4 of cooling system；Carbide slag slurries go out from tower bottom
It send after coming to carbide slag slurries processing system.Carbide slag slurries enter desorption tower in moment by efficient turbulence, dispersion, the surface of increase
Product is conducive to acetylene gas and discharges rapidly, meanwhile, multilayer tower tray is devised in desorption tower 3, each layer tower tray is gas phase water conservancy diversion tower tray, respectively
Layer tower tray and horizontal direction are distributed in 5-7 ° of angle.To increase residence time of the carbide slag slurries in tower.In addition, the gas-liquid of desorption tower
Separative efficiency is higher, avoids carbide slag slurries with acetylene gas and vapor and enters subsequent cooling system, causes cooling system and true
Sky pump fouling, avoiding cooler heat exchange efficiency reduces the problems such as high with vacuum pump failure rate.
The vapor and acetylene gas come out from desorption tower top exit enters three-level cooling system, respectively evaporating type condensing
Device 4, water recirculator 5 and freezing water cooler 6.Wherein evaporative condenser uses air heat-exchange, greatly reduces circulation
The consumption of water and chilled water improves the economy of device operation.After vapor is condensed, condensate liquid enters condensate drum, second
After alkynes temperature degree is cooled to 25 DEG C or less, sent after being boosted by vacuum pump to acetylene surge tank.
Oxygen content in online oxygen conten analyser detection acetylene gas, qualified acetylene are sent into acetylene cleaning system, unqualified second
Alkynes is exhausted by exhausting pipeline.
The condensate liquid to cool down from three-level cooling system enters condensate drum, then is pumped to acetylene by condensate liquid and fills
It sets, realizes that condensate liquid comprehensively recyles.The acetylene for realizing and recycling condensate liquid, and can will be dissolved in condensate liquid
Gas recycles.
