Description
(1) technical field
The utility model relates to a kind of m-dicyanobenzene waste water just to be handled and uses the hot pressing filter, belongs to technical field of chemical.
(2) background technology
Between benzonitrile have another name called different phthalonitrile, be a kind of important meticulous organic chemical industry's intermediate, but its synthesizing fungicide Bravo also can be used as the raw material of products such as plastics, m-xylene diamine and synthetic fibers polyurethanes.1969, U.S. Dianond Shamrook company and Japan are clear formally to produce with electrician company.Early 1980s China's synthetic method that begins one's study, and carry out industrial experiment production, Hunan insecticide factory builds up 70t/a pilot-scale process units at first.At present domestic existing 8 families have respectively more than various large-scale production device 10 covers, yearly productive capacity reaches 5000t/a, and 90% above product is used to produce Bravo in the actual production, and a spot of product is used to produce m-xylene diamine, the portioned product outlet, price is generally about 3.2 ten thousand yuan/t.At present, the commercial run of producing isophthalodinitrile all adopts the ammoxidation of m-xylene method both at home and abroad, in course of reaction, because a large amount of liquefied ammonia that use, excessive liquefied ammonia produces a large amount of remaining ammonias, for fear of the harm of ammonia to environment, change original conventional dried rewinding mode, and the method that the water spray is absorbed absorbs material and ammonia get off, reaction temperature reaches 200--300 ℃, and after the m-dicyanobenzene filtration of spray end with high-load, the mother liquor water temperature still reaches 50--70 ℃, after putting into the wastewater disposal basin cooling, contain part m-dicyanobenzene and side reaction product amide-type in the waste water, amine, salt impurity is all separated out, the wastewater treatment difficulty is strengthened greatly, in order to handle this waste water, and obtain content and be higher than 96% m-dicyanobenzene, reduce cost, adopt solvent xylene directly waste water to be extracted, but dimethylbenzene need could dissolve m-dicyanobenzene fully at 70--100 ℃, temperature reduces a little and just has m-dicyanobenzene and separate out, and conventional pressure filter is difficult to satisfy the requirement of m-dicyanobenzene waste water treatment process.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be under than higher temperature with dissolved substances separated, reduced cost with dissolved impurity not, reduced the shower water consumption, the m-dicyanobenzene waste water that reduces wastewater flow rate just handles and uses the hot pressing filter.
The purpose of this utility model is achieved in that a kind of m-dicyanobenzene waste water is just handled and uses the hot pressing filter, and it is characterized in that it comprises cylindrical shell, orifice filter and filter cloth, described cylindrical shell is open type reactor structure, has chuck,
Described cylindrical shell upper portion side wall is provided with charging aperture and nitrogen mouth, and described cylindrical shell bottom is provided with discharging opening,
Described cylinder top cover is a fast-open type, covers on described to have drain,
Described orifice filter is arranged at the inner chamber bottom of described cylindrical shell, and described filter cloth is fixed on the described orifice filter.
The utility model m-dicyanobenzene waste water is just handled and is used the hot pressing filter, and described filter cloth is fixed on the described orifice filter by a ring-type iron ring.
The utility model m-dicyanobenzene waste water is just handled and is used the hot pressing filter, can be under than higher temperature dissolved substances be separated with dissolved impurity not, greatly reduces cost, reduces the shower water consumption, has reduced wastewater flow rate.
(4) description of drawings
Fig. 1 just handles with hot pressing filter structural representation for the utility model m-dicyanobenzene waste water.
Among the figure: cylindrical shell 1, orifice filter 2, filter cloth 3, charging aperture 4, discharging opening 5, nitrogen mouth 6, thermometer mouth 7, loam cake 8, drain 9, chuck 10, gauge port 11.
(5) specific embodiment
Referring to Fig. 1, the m-dicyanobenzene waste water that the utility model relates to is just handled and is used the hot pressing filter, comprise cylindrical shell 1 and orifice filter 2 and filter cloth 3, described cylindrical shell 1 is with general open type reactor structure, at the bottom of circular arc, bottom valve is arranged, cylindrical shell has chuck 10, by walking heat medium and cooling medium for 10 li at chuck, realizes the temperature control of equipment, 20-40cm place, cylindrical shell 1 top has charging aperture 4 and nitrogen mouth 6 and thermometer mouth 7 respectively, loam cake 8 is a fast-open type, for making things convenient for the discharging of the solid impurity that press filtration comes out, has drain 9 on the loam cake 8 simultaneously, gauge port 11, visor etc.Described orifice filter 2 is arranged at the inside of described cylindrical shell 1, and the position is in the bottom, and filter cloth 3 is fixed on the orifice filter 2 by a ring-type iron ring.
During operation, close loam cake 8, add nitrogen by nitrogen mouth 6 earlier, the air in the exchange system, use the heat medium in the chuck 10 to guarantee that equipment is at 70--100 ℃, open charging aperture 4 valves and discharging opening 5 valves, other valve closings, material is pressed into cylindrical shell 1 by nitrogen then, filter, solid is stayed in the cylindrical shell 1, and liquid carries out crystallisation by cooling after flowing out via discharging opening 5.After treating that material has been pressed, close charging aperture 4 valves, open nitrogen mouth 6 valves, the solid that will wet press dry as far as possible, after pressing dry, close chuck 10 heat medium terminal valves, open the cooling medium terminal valve, cooling, after cooling finishes, open loam cake 8, the solid of staying in the cylindrical shell 1 is dug out, close loam cake 8, treat operation next time.
Use the utility model m-dicyanobenzene waste water just to handle with behind the hot pressing filter device, can satisfy the press filtration in the time of 70--100 ℃ temperature fully, a spot of meta-xylene in the waste water is proposed, its content reaches more than 96%, amide-type impurity in the waste water is proposed, its content reaches more than 80%, the COD of waste water has original 14000ppm to reduce to below the 5000ppm, and the spray that can directly be re-used in next time absorbs material, produce economic benefit, be elevated to more than 85% 80%, greatly reduce cost, reduce the shower water consumption, reduced wastewater flow rate.
