Abstract
The utility model discloses an installation for recycling acetylene gas-purifying sodium hypochlorite solution. The installation comprises a waste sodium hypochlorite solution storage tank, a pump, a spiral-plate heat exchanger, a gas-water separator, an acetylene cooler, a stripper, a cooling tower and a neutralizing and coagulating tank which are sequentially connected. The installation heats the waste sodium hypochlorite solution with low-pressure steam, and sends the waste sodium hypochlorite solution into the gas-water separator, so that acetylene gas can be sufficiently volatilized, and thereby the acetylene gas is recovered. The waste sodium hypochlorite solution removed of the acetylene gas undergoes stripping and coagulant sedimentation, the supernate is sent into a fresh sodium hypochlorite preparation pipeline, and thereby the waste sodium hypochlorite solution is recycled. Since the utility model recovers the acetylene gas from the waste sodium hypochlorite solution, the consumption of calcium carbide is reduced, the waste water can be reused in the preparation of fresh sodium hypochlorite, and therefore, a great deal of water is saved. The utility model has the technical effects of energy saving, consumption reduction, emission reduction and environment protection.
Description
Technical field:
The utility model relates to a kind of device of recycling trade effluent, is specifically related in the acetylene gas cleaning technique, to the device of cleaning liquor clorox recycling.
Background technology:
In the acetylene production process, comprise the cleaning technique of acetylene gas.Peace and quiet acetylene gas generally adopts the clorox cleaning liquor.Through containing a certain amount of acetylene gas, Cl root in the useless sodium hypochlorite solution after the peace and quiet operation, be difficult to be applied to often all efflux in other explained hereafter without processing, bring very big burden to sewage disposal, increased environmental protection pressure; Need a large amount of waters and prepare clorox on the other hand, bigger to the water resources consumption amount.
The utility model content:
The purpose of this utility model is to provide a kind of device that clorox cleaning liquor in the acetylene cleaning technology is recycled.
The fresh clorox pH value of peace and quiet process configurations is 7-8, and available chlorine content is between 0.02-0.12%.Clorox carries out peace and quiet in peace and quiet tower to acetylene gas, extracted out by the producer service pump afterwards, goes forward side by side into water wash column by the spiral-plate heat exchanger cooling in service pump exit, and acetylene gas is lowered the temperature, and the peace and quiet operation of acetylene gas is finished.The device that the utility model is recycled the useless sodium hypochlorite solution that comes out from water wash column comprises:
Useless sodium hypochlorite solution storage tank, useless clorox lift pump, spiral-plate heat exchanger, air water separator, acetylene water cooler, above equipment is linked in sequence.
Device of the present utility model also comprise gas stripping column, cooling tower, in and coagulation basin, settling tank, above equipment is linked in sequence.
Gas stripping column can comprise one-level gas stripping column, secondary gas stripping column.
Useless sodium hypochlorite solution storage tank, pump, spiral-plate heat exchanger, air water separator, acetylene water cooler are used for removing the acetylene gas of useless sodium hypochlorite solution: the clorox overflow of water wash column bottom enters useless sodium hypochlorite solution storage tank, and dissolved part acetylene gas reclaims by carrying out balance between storage tank and the acetylene gas house steward; The sodium hypochlorite solution that gives up is extracted out by useless clorox lift pump, uses the low-pressure steam heat temperature raising to 70-75 ℃ at the pump discharge place through spiral-plate heat exchanger; Useless sodium hypochlorite solution enters air water separator, makes that the dissolved acetylene gas fully volatilizees in the waste water; The gaseous phase outlet pipe of acetylene gas through the steam separator top enters the cooling of acetylene water cooler, cooling, dehydration, enters acetylene water-ring pump inlet pipe then, reaches the purpose that reclaims acetylene gas;
Gas stripping column, cooling tower, in and coagulation basin, settling tank be used to recycle useless sodium hypochlorite solution: remove useless sodium hypochlorite solution behind the acetylene and deliver to gas stripping column by transferpump and carry out gas and carry; With the useless sodium hypochlorite solution in the gas stripping column tank be promoted to cooling tower, in and coagulation basin, the pH value of this stage waste water is modulated to 6-9, add flocculation agent or iron trichloride, make it abundant reaction, all kinds of suspended matters form floss under the coagulation of molysite, PAM; Mixed solution enters settling tank, carries out the gravity separation sedimentation, and clorox configuration water pipeline was sent into by the supercharging of reuse pump in the pond during supernatant liquor flow to, and directly as the configuration of fresh clorox, floss effluxes.
Can from useless sodium hypochlorite solution, farthest reclaim acetylene gas by device of the present utility model, not only can reduce consumption of raw material calcium carbide, and make waste water can be reused for configuration fresh clorox, water saving in large quantities because of no longer containing in the waste water with the meet acetylene gas that has explosion hazard of chlorine.The utlity model has energy-saving and cost-reducingly, reduce discharging the technique effect of environmental protection.
Description of drawings:
Fig. 1 is a process flow sheet of the present invention.
Equipment and the process schematic representation of Fig. 2 among the present invention acetylene gas in the useless sodium hypochlorite solution being recycled.
Equipment and the process schematic representation of Fig. 3 among the present invention the useless sodium hypochlorite solution that has removed acetylene gas being recycled.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing.
The fresh clorox pH value of acetylene cleaning process configurations is 7-8, and available chlorine content is between 0.02-0.12%.As shown in Figure 1 and Figure 2, the 1-sodium hypochlorite solution storage tank that gives up, the 2-clorox lift pump that gives up, 3-spiral-plate heat exchanger, 4-air water separator, 5-acetylene water cooler, 6-producer service pump, 7-spiral-plate heat exchanger, 8-water wash column.
Clorox is finished in peace and quiet tower behind acetylene gas peace and quiet, take out 6 by the producer service pump and go out, go forward side by side into water wash column 8, acetylene gas is carried out spraying cooling by spiral-plate heat exchanger 7 coolings in producer service pump exit, so far, the cleaning technique of acetylene gas finishes.Enter the technology that the present invention recycles the clorox cleaning liquor below.
At first the acetylene gas in the useless sodium hypochlorite solution is reclaimed, technology is as follows:
1, useless sodium hypochlorite solution enters useless sodium hypochlorite solution storage tank 1 from water wash column 8 bottom overflows, and dissolved part acetylene gas carries out the balance recovery by storage tank 1 with the acetylene gas house steward in the waste water;
