In dry residue generator, the production pressure of acetylene and carbide slag separator is more than 0.3MPa, and the tap density of carbide slag is about 0.7kg/L.The actual specific gravity of carbide slag is 2.2kg/L, thus not compressed carbide slag, actual discharge 1m
3Carbide slag will discharge about 0.65m at least
3Steam-laden acetylene gas, the wherein about 0.1625m of acetylene gas
3And produce 60000 tons of polyvinyl chloride per year, when calcium carbide generation tolerance is 285Nm
3/ t, per hour the long-pending density of the accumulation of Chan Shenging is the about 22.79m of carbide slag of 0.7kg/L
3/ h.The about 3.7m of acetylene gas that discharges
3/ h, and the limits of explosion concentration of acetylene and air mixture is 2.3～72.3% (volumes).So effectively handle without strictness when carbide slag, the carbide slag that will contain acetylene gas is very dangerous from the separator discharge.
The carbide slag custody transfer of separating acetylene gas is a not only safety but also can reduce the dust pollution that other remote conveying brings to the carbide slag feed bin in cement mill.But must solution how to avoid pressurized air to enter the problem of dry residue generator system.

Enter acetylene gas and carbide slag separator 1 from the acetylene gas (moisture vapor) of dry acetylene generator with based on the carbide slag of calcium hydroxide by the carbide slag and the acetylene gas import 1.1 at acetylene gas and carbide slag separator 1 top, because acetylene gas and carbide slag separator top gas speed drop to below 1 meter per second, the acetylene gas of moisture vapor, acetylene gas venting port 1.2 by acetylene gas and carbide slag separator 1 upper lateral part enters scrubber tower, carbide slag is deposited in acetylene gas and carbide slag separator bottom, by the weight of weight sensor 1.4 weight metering carbide slags in acetylene gas and carbide slag separator, control three variables aborning, it is the low material level value of amount of carbide slag, the amount high charge level value of carbide slag and the intermediate value of carbide slag, the amount high charge level value of carbide slag guarantees that mainly carbide slag does not diffuse in the acetylene washing tower from acetylene gas and carbide slag separator.The low material level value of the amount of carbide slag guarantees mainly that acetylene gas is not scurried into from acetylene gas and carbide slag separator and captures scrubber tower 3, and the intermediate value of carbide slag i.e. the intermediate controlled value of material level up and down.When continuous production, control intermediate controlled value, when material level by intermediate value to rising, but this moment synchronization regulation first the screw rod conveyor 2 and current of electric frequency of second screw rod conveyor 8, and slightly increase the rotating speed of first screw rod conveyor 2 and second screw rod conveyor 8.Otherwise otherwise.When near the highest control material level, should increase by two envelope gas screw rod conveyor rotating speeds rapidly synchronously, when carbide slag during, can cut off the power supplys of two envelope gas screw rod conveyors immediately to minimum control material level, stop the discharging of acetylene gas and carbide slag separator.About about 105 ℃ of the carbide slag temperature of acetylene gas and carbide slag separator, pressure is about 0.03Mpa.The volume ratio of water vapor and acetylene gas is 3:1 in the acetylene gas.About the about 0.7kg/L of carbide slag tap density, moisture about 4～10%.In order not influence weight metering, all adopt soft the connection with acetylene and carbide slag separator connection line.
Owing to contain a large amount of water vapors in the acetylene gas, for fear of water vapor condensation and cause acetylene gas and the fouling of carbide slag separator barrel, separator is provided with steam jacket, is incubated with 100～110 ℃ of low-pressure steam.Low-pressure steam is entered by steam inlet 1.6, coagulates with fixed attention water out 1.7 dischargings of water by the chuck bottom.
The carbide slag of moisture 4～10% about 105 ℃ enters first screw rod conveyor 2 by the carbide slag opening for feed 2.1 of first screw rod conveyor 2, and through first section compression screw rod, the carbide slag tap density increases to about 1.1kg/L about by 0.7kg/L.Most of gas is pressed into the separator of acetylene gas and carbide slag, carbide slag is at the pitch expanding reach, tap density descends again, be provided with the suction opening 2.2 that captures acetylene gas herein, with negative pressure the acetylene gas suction more than 90% is captured scrubber tower 3, the carbide slag temperature also drops to below 90 ℃ by about 105 ℃ simultaneously, and carbide slag is moisture also to descend to some extent.The screw rod of one section band compression ratio is arranged again in first screw rod conveyor, 2 rear ends, carbide slag density is increased to about 1.15kg/L by 0.8kg/L.In fact the carbide slag of the increase density in the screw rod can seal the gas of 0.1Mpa air pressure, and is entered the carbide slag opening for feed 8.1 of second screw rod conveyor 8 by the carbide slag discharge port 2.3 of first screw rod conveyor.First screw rod conveyor 2 adopts speed control by frequency variation.
Pressurized air for fear of gas delivery enters first screw rod conveyor, and second screw rod conveyor remains by the screw rod of band compression ratio to be formed.Compression ratio control 1.5～2:1.Carbide slag is controlled at more than the 1.1kg/L in screw rod tail density.Pressurized air with sealing 0.1Mpa pressure is scurried into first screw rod conveyor.The carbide slag of compression enters jet-type gas delivery loader 9 by the carbide slag discharge port 8.2 of second screw rod conveyor, uses the air delivery tube 9.3 that carbide slag is blown into jet-type gas delivery loader less than the pressurized air of 0.1Mpa.At this moment, in the gas delivery gas separated, acetylene content can be reduced to below the 50PPm, reaches the safety dumping standard fully.Carbide slag contains calcium carbide less than 0.1%.If the pressurized air of gas delivery heats, carbide slag is moisture can be less than 4%.
By the acetylene gas of first screw rod conveyor through the moisture vapor of negative pressure extraction, control gas speed is less than 1 meter per second, to avoid carrying secretly a large amount of carbide slags, enter capture scrubber tower 3 by acetylene gas import 3.1, about 80～90 ℃ of inlet air temperature is with containing the washing of calcium hydroxide 4～10% recirculated cooling waters, 50～60 ℃ of temperature of washing water, spray into capture scrubber tower body of the tower 3.7 by three circulation fluid nozzles 3.3, liquid-gas ratio control 2～5L/m
3Be used for washing the dust that separates acetylene gas, absorb the water vapor in the acetylene gas, reduce the acetylene gas temperature, washings captures the outlet 3.5 of gas washing liquid after gas washing liquid recycle pump 4 and 5 coolings of gas washing liquid interchanger by capturing scrubber tower, enter circulation fluid nozzle 3.3, the circulation gas washing liquid tower jar 3.6 that captures the scrubber tower bottom has liquid level indication Controlling System.When material level rises to vertex, promptly open the fluid mouth of pipe 4.3 valves, excessive liquid is delivered to withdrawing can, when reaching liquid level, promptly close the fluid mouth of pipe 4.3 valves, controlling certain calcium hydroxide concentration is in order to reduce the consumption of water.Washing lotion can be used for wet type desulfurizing, and the carbide slag after the press filtration also can be used for manufacture of cement.Replenish liquid nozzle 3.4 and regularly use clear water to purge wall, to avoid the fouling of tower wall.
The acetylene gas that most of water vapor is sloughed in cooling enters capture surge tank 6 by the acetylene gas outlet 3.2 that captures the scrubber tower cat head, separates the water smoke that acetylene gas is carried secretly, and acetylene gas is sucked and drained into the scrubber tower of dry acetylene formula generation systems by water-ring vacuum pump 7.Vacuum degree control 10～30Kpa.
