Description
One, technical fields：
The present invention relates to commercial explosive production field, more particularly, to a kind of new method of processing DDNP waste water, specifically
It is the method that its Heat Treatment DDNP waste water is utilized by technological transformation rotary cement kiln.
Two, background technologies：
At present, in industrial detonator manufacturing enterprise, priming is the basic medicament of blasting cap initiation.Priming species is various, mesh
Preceding domestic many enterprises are due to the pressure being environmentally protected, and production and wastewater treatment to priming medicament are put into substantial amounts of
Resource.Especially DDNP primings are dinitrodiazophenol, and the priming has higher flame sensitivity and mechanical sensitivity, and it is produced
Product superior performance, production cost is low.But it is due to that the wastewater flow rate produced in its production process is larger, and intractability is larger, separately
Many generation enterprises use other primings instead, and the cost of transformation input is greatly increased.
Ddnp is the english abbreviation of dinitrodiazophenol, the nitro-derivative of phenol, is a kind of important in detonator industry
Priming, has the advantages that good detonation performance, abundant raw material, with low cost and production operation are comparatively safe and wide
It is general to use, especially it is widely used in process industry blasting cap.But, ddnp production waste water in containing dinitrodiazophenol,
The multiple harmful substances such as nitro compound, sulfide, phenols, colourity is high, and COD is big, and the toxicity of contained pollutant
Greatly., must and the wastewater flow rate produced by often producing one kilogram of ddnp just has 150~250kg, is discharged everywhere as untreated
So pollute the environment, influence water body around ecological environment and neighbouring resident it is healthy.So must do well to waste water
Work is handled, eliminates and poisons, comprehensive utilization, changing waste into valuable is the big problem of environment of significant.
The three, content of the invention
The present invention in view of the above-mentioned problems, by with the existing cement production enterprise cooperation in periphery, use low cost to improve existing water
Mud rotary kiln, using the waste heat of the rotary cement kiln after technological transformation, has nearly 1000 degree of high temperature, processing is evaporated to waste water, at waste water
Manage after finite concentration, carry out burning disposal, reduce environmental pollution, technological transformation difficulty, reduction processing DDNP waste water can be reduced again
Cost.
Specific method is as follows：
1. the DDNP waste water that detonator production enterprise is collected, with watery hydrochloric acid or sodium acid carbonate, pH value is handled to 6.5~
7.0 scopes, are transported to cement production enterprise using groove tank car, are treated in the DDNP wastewater disposal basins (1) for injecting the rotary cement kiln after technological transformation
With；
2. the DDNP waste water in collecting pit is pumped to and rotary cement kiln (4) outer wall by pumping pump (2) and delivery pipe (3)
In the heated tank body (6) of close connection, DDNP waste water is from top due to Action of Gravity Field from top to bottom and by being installed in tank body (6)
Spacer web (9) so that DDNP waste water uniformly flows down heated, and because tank body (6) is brought into close contact with rotary cement kiln (4), cement revolves
Kiln (4) waste heat can heating tank body (6) reach 1000 DEG C or so.
3.DDNP waste water in tank body (6) it is uniform flow down it is heated after, after the stream of bottom, by return duct (5) and delivery pump
(7) again in pumped back tank body (6), and using Action of Gravity Field from top to bottom and by the spacer web (9) of installation in tank body (6),
It is heated so that DDNP waste water uniformly flows down.
4. after several circulations, DDNP waste water is heated to be evaporated to concentration after 10%-20%, will be arranged on return duct
(5) triple valve (10) between delivery pump (7), which is opened, to introduce wastewater collection by the DDNP waste water of heating evaporation several times
In pond (8), the waste water after collection is subjected to burning disposal again.
It is preferred that, the amount of pumping processing DDNP waste water is preferred in 1000Kg every time.
It is preferred that, the time control of cyclic process of a DDNP waste water is handled at 30 minutes or so.
Advantage of the present invention：
1. whole processing procedure uses physics mode, the moisture content in a large amount of DDNP waste water is evaporated, does not increase pollutant generation.
2. technological transformation cost is low, water reuse, conventional cement rotary kiln is also required to utilize water resource cooling.
3. the cost of business processes DDNP waste water is substantially reduced, with huge social benefit.
Four, are illustrated
Fig. 1 is that the present invention utilizes the cement after the technological transformation of the method for its Heat Treatment DDNP waste water by technological transformation rotary cement kiln
Rotary kiln structural profile schematic diagram.
Brief description of the drawings is as follows：1st, wastewater disposal basin；2nd, pump is pumped；3rd, delivery pipe；4th, rotary cement kiln；5th, return duct；6th, tank body；7、
Delivery pump；8th, wastewater collection pond；9th, spacer web；10th, triple valve.
Five, embodiments
Below in conjunction with the accompanying drawings 1 and embodiment the present invention is described in further detail.As shown in the figure：
1st, the DDNP waste water progress watery hydrochloric acid or sodium acid carbonate PH collected detonator production enterprise are extremely handled to 6.5-
7.0 scope.Transport stand-by into the DDNP wastewater collection ponds or storage tank of cement production enterprise using groove tank car.
2nd, DDNP waste water is by pumping pumping 1000Kg to the top of rotary cement kiln Heat Treatment device, waste water from top by
In Action of Gravity Field from top to bottom, because device is brought into close contact with rotary cement kiln, 1000 DEG C or so of rotary cement kiln waste heat.
3rd, the DDNP waste water of rotary cement kiln Heat Treatment device is pumped to, circulates and is heated by device, when in cyclic process
Between 30min, by discharging opening carry out liquid waste concentration detection, when liquid waste concentration Testing index reaches the 10%-20% of requirement model
When enclosing interior, the DDNP waste liquids after processing are handled by the collection of waste collection pond, after being stood after Temperature fall, carried out at burning
Reason.
