Technical field
The utility model relates to a kind of other retrieving arrangements, particularly a kind of device that reclaims acetylene from carbide slag slurries.
Background technology
Acetylene is colourless gas, has the ether flavor, and molten and pure and mild ketone is one of important source material of organic synthesis, can produce acetaldehyde by acetylene, acetic acid, vinylchlorid, the multiple Organic Chemicals such as acetic acid diene.Acetylene is the important monomer of synthetic rubber, fiber and plastics, and acetylene can be directly used in cutting and the welding of metal.At present, calcium carbide route is mainly adopted in the production of domestic acetylene, namely directly prepares acetylene gas with solid calcium carbide and water mutual reactance, and its chemical equation is as follows:
CaC
2?+?2H
2O?→?C
2H
2?+?Ca(OH)
2
This technical process is simple, and operation is convenient, yet the calcium carbide hydrolysis method is polluted large, water loss is high, and one ton of acetylene of every production consumes 25 tons in water, produces 28 cubic metres of waste water and dregs, and remaining a large amount of acetylene gas in the carbide slag slurries that produces, it is large to process labour intensity with conventional way, and expense is high.At present way commonly used is that the slag slurry is introduced concentration basin, allows wherein remaining acetylene gas volatilization, and this has not only caused a large amount of wastes, simultaneously because the inflammable and explosive characteristic of acetylene exists larger potential safety hazard.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the weak point of prior art, remaining acetylene in the energy efficient recovery carbide slag slurries to be provided, greatly reduce the wasting of resources, having reduced a kind of device that reclaims acetylene from carbide slag slurries of potential safety hazard.
The technical solution of the utility model is: a kind of continous way reclaims the device of acetylene from carbide slag slurries, this device has comprised the carbide slag stock tank, machine mixer, the carbide slag stock pump, stripping tower, condenser, surge tank and Root's blower, described carbide slag stock tank acetylene reactor links to each other, be provided with stirrer in the carbide slag stock tank, its outlet line links to each other with the carbide slag stock pump, the carbide slag slurries pump discharge links to each other with the stripping tower entrance, the carbide slag slurries that is rich in acetylene is squeezed in the stripping tower by the slag stock pump from the carbide slag stock tank, the stripping tower outlet is divided into set out on a journey gaseous phase outlet and lower road liquid-phase outlet, wherein, gaseous phase outlet links to each other with condenser, liquid-phase outlet links to each other with slag slurry blow-off pipe, condensator outlet links to each other with surge tank, is connected with Root's blower behind the surge tank, and the acetylene gas of recovery enters the acetylene products pot through Root's blower.
This device also is connected to device is carried out the nitrogen collection dress lattice that gas displacement is used, and described carbide slag stock tank is provided with in addition one road entrance and links to each other with nitrogen collection dress lattice.The beneficial effects of the utility model are: adopt this system, effectively reclaimed acetylene gas remaining in the carbide slag slurries, reduced waste, saved resource, improved product yield, reduced because environmental pollution and the potential safety hazard that the volatilization of acetylene gas causes.Simultaneously, adopt this system, alleviated and processed the labour intensity that dreg slurry brings, reduced expense, created certain economic benefit.

Among the figure: 1. the nitrogen collection fills lattice, 2. carbide slag stock tank, 3. machine mixer, 4. carbide slag stock pump, 5. stripping tower, 6. condenser, 7. surge tank, 8. Root's blower, 9. nitrogen pipe connecting, 10,11,12. acetylene pipe connectings, 13. blow-off pipe, 14. the acetylene pipe connecting, 15. blow-off pipes, 16. acetylene pipe connectings.
Embodiment
Be depicted as a kind of continous way reclaims acetylene from carbide slag slurries device such as figure one.Shown in figure one, enter the carbide slag stock tank from the carbide slag slurries of acetylene reactor, open machine mixer (3), through mechanical stirring, the solid particulate in the carbide slag slurries is mixed.Slowly squeeze in the stripping tower (5) through the carbide slag stock pump through the carbide slag slurries that mixes after stirring, carbide slag slurries is realized separating in stripping tower, under vacuum state, dissolve, be adsorbed in that the acetylene gas of slag in starching is flashed in gas stripping column, stripping out; Simultaneously, under action of gravity, directly enter slag slurry pond for recovering by the stripping tower bottom by blow-off pipe (13) through the carbide slag slurries behind the stripping, realize gas solid separation.
The acetylene gas that obtains through stripping contains a large amount of water vapour, has affected the quality of acetylene, therefore, behind stripping tower, be connected with condenser (6), outlet enters condenser to the thick product of acetylene that obtains through stripping through stripping tower top, and condenser adopts the refrigerated water cooling, and chilled water temperature is set in 6
oC, through condenser, the vaporous water lease making is condensed into liquid water, thereby acetylene gas is separated with moisture.
Enter acetylene surge tank (7) through condensed acetylene gas, the acetylene surge tank is connected with Root's blower (8), and acetylene gas is realized the recovery of acetylene gas through Root's blower suction acetylene products pot.
This device is connected with oxygen on-line detecting system, automatic control system and emptying valve, the oxygen on-line detecting system is the interior oxygen content of supervisory system at any time, in case oxygen content surpasses set(ting)value, automatic controlling system is produced and is stopped at once, the emptying valve open, system carries out emptying, has guaranteed the safe operation of producing.
Acetylene gas is inflammable and explosive, in order to prevent residually in the retrieving arrangement having air to bring potential safety hazard to production operation, when operation, emitting nitrogen first from nitrogen collection dress lattice (1) replaces system, detect online the oxygen content of system when oxygen in the safety rhetorical question, can produce, be down to minimumly to guarantee intrasystem air content, get rid of potential safety hazard.
Seamless welding is all adopted in the connection of all acetylene pipe connectings (10,11,12,14,16) in this device, guarantees that each corner stopping property is better.
This patent has thoroughly solved the difficult problem that the slag slurry is processed in the existing equipment, after the recovery, and content average out to 6.5 mg/L of acetylene gas in the slag slurry, organic efficiency reaches 96.9%.Produce per month 1500 tons of acetylene according to company and calculate, 135 tons of annual recyclable acetylene, the company that can be every year creates 1,500,000 yuan benefit nearly, and input cost only is 200,000.
