The lower side of neutralization pond described in the utility model is connected to a recovery tube, and recovery tube is provided with recovery valve.
Liquid circulating device described in the utility model comprises motor, circulating pump, the 3rd, the 4th pipeline and shower nozzle, motor and circulating pump assembly and be installed in the top of described neutralization pond, one end of the 3rd pipeline is connected with the inlet of circulating pump, the other end is insinuated in the neutralization pond, one end of the 4th pipeline is connected with the liquid outlet of circulating pump, the other end is stretched over the top of purifying column, and shower nozzle has one group, is configured on the 4th pipeline that is stretched in the purifying column and corresponding to the top of described packing layer.
The advantage of technical scheme disclosed in the utility model: under the effect of liquid circulating device; waste acid water in the neutralization pond is introduced purifying column; to be incorporated into the ammonia-containing exhaust spray in the purifying column by second pipeline; be back to neutralization pond through first pipeline; the ammonium sulfate liquid circulating and recovering that is generated in the neutralization pond is in imidazolidine is produced; and the gas that the blast pipe of auto purification tower is discharged is the qualified discharge gas after purifying, and has therefore both embodied the protection environment, has brought into play the effect of resource reutilization again.
Description of drawings
Accompanying drawing is a specific embodiment structure chart of the present utility model.
The specific embodiment
See also accompanying drawing, provided a neutralization pond 1, under user mode, neutralization pond 1 is a carrier with the terrace, promptly finds a place on terrace, at a side lower part of neutralization pond 1 is that the bottom on the right side of location status shown in the accompanying drawing is furnished with a recovery tube 11, recovery tube 11 is provided with recovery valve 111, when the concentration of the ammonium sulfate liquid in the neutralization pond 1 reaches necessary requirement, then opens recovery valve 111, ammonium sulfate liquid is emitted, be back to the production technology of imidazolidine after treatment.At the opposite side of neutralization pond 1 is that the top in illustrated left side is linked with a waste acid water inlet tube 12, by this waste acid water inlet tube 12 waste acid water that is produced in the imidazolidine production technology is introduced in the neutralization pond 1.
Continue to see accompanying drawing, above neutralization pond 1, purifying column 2 is set by support 25, the top of this purifying column 2 is that narrow the contracting of cat head is formed with a blast pipe 24, and the central region in the purifying column 2 is laid packing layer 21, and the material of packing layer 21 for example adopts active carbon or other materials similar.The lower side of purifying column 2 is connected in first, second pipe an end of 22,23, wherein, the other end of first pipeline 22 is connected with neutralization pond 1 and communicates, and the other end of second pipeline 23 is connected with the gas outlet of blower fan 3, the air inlet of blower fan 3 is connected with ammonia-containing exhaust pipeline 4, and the ammonia-containing exhaust that comes from used reactor in the synthetic reaction step of imidazolidine production is incorporated in the cavity of resorption of purifying column 2 through ammonia-containing exhaust pipeline 4.
Still see accompanying drawing, one cover liquid circulating device 5 is installed on the neutralization pond 1, specifically: with motor 51 and circulating pump 52 by the ways customary assembly in the prior art and place the top of neutralization pond 1, one end of the 3rd pipeline 53 is docked with the inlet of circulating pump 52, the other end of the 3rd pipeline 53 extend in the neutralization pond 1, one end of the 4th pipeline 54 docks with the liquid outlet of circulating pump 52, the other end is stretched in the purifying column 2, and corresponding to the top of described packing layer 21, and with one group of shower nozzle 55 with state spaced apart be fixed on the 4th pipeline 54 and be positioned on the body of purifying column 2.
