Abstract
The utility model provides a phenolic resin waste liquid separation and recovery device which mainly comprises an extraction tank and a recovery tank, wherein both the extraction tank and the recovery tank are provided with a liquid inlet valve and a liquid drain valve, a connecting pipe is arranged at the upper end of the extraction tank and communicated with the recovery tank, and the extraction tank is provided with a heating device. Since the boiling point of formaldehyde is lower than that of phenolic compounds, the heating device can raise the temperature of the liquid inside the extraction tank up to the boiling point of formaldehyde, thereby separating formaldehyde from the waste liquid. A vacuum pump is arranged on the extraction tank and communicated with the inside of the extraction tank. The vacuum pump is adopted to reduce the gas pressure inside the extraction tank and thus to reduce the boiling point of formaldehyde in the waste liquid. The separated formaldehyde from the waste liquid is delivered to the recovery tank through the connecting pipe and then cooled and recovered in the recovery tank. The device increases the purity of the liquid solution after recovery, eliminates pollutant emission, reduces the treatment cost, greatly reduces enterprise's investment for toxic waste treatment, and increases the production benefit of the enterprise.
Description
Technical field
The utility model relates to a kind of waste disposal plant, and particularly a kind of resol is discarded the liquid separating and reclaiming device.
Background technology
At present, need to use resol in copper-clad plate basal plate production process, can produce a large amount of phenolic aldehyde sewages in the process of producing resol, its main component is formaldehyde and various phenols chemicals, and the sewage complicated component of this type is difficult to recycle.Original heating polycondensation method occurs multiple heterogeneous in the resol after the recovery.Can not generate stable resol, can not methylate.Derived product is when using the resol of these recovery, and changes in process parameters is big, can not form stay-in-grade product.
In sum: need at present that a kind of technical process is simple, heterogeneous few in the material that reclaims, the phenolic aldehyde of chemical composition stability is discarded the liquid separating and reclaiming device.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, designs that a technical process is simple, heterogeneous few in the material that reclaims, and the phenolic aldehyde of chemical composition stability is discarded the liquid separating and reclaiming device.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of resol is discarded the liquid separating and reclaiming device, and primary structure comprises extractor and withdrawing can, and extractor and withdrawing can all are provided with feed liquor valve and tapping valve, is provided with conduit in the extractor upper end and is communicated with withdrawing can, and extractor is provided with heating unit.Because the boiling point of formaldehyde is lower than the boiling point of phenolic compound, the temperature that heating unit can improve solution in the extractor reaches the boiling point of formaldehyde, allows formaldehyde separate from discarded liquid.Because phenolic wastewater is heated to after the certain temperature polycondensation can take place, prevent polycondensation again for formaldehyde can be separated from discarded liquid, thus on extractor, be provided with extractor in the vacuum pump of UNICOM.Utilize vacuum pump to reduce the interior air pressure of extractor to reduce the boiling point of formaldehyde in the discarded liquid.The formaldehyde of separating from discarded liquid is delivered to cooling recovery in the withdrawing can by conduit.
Recovery liquid is housed in the withdrawing can, and described recovering liquid is a formaldehyde solution.The end that conduit is positioned at withdrawing can extends under the liquid level that reclaims liquid, and formaldehyde was recovered the liquid absorption when formaldehyde steam process reclaimed liquid.By constant voltage pipe UNICOM, the constant voltage pipe plays the effect of balanced extractor and withdrawing can internal gas pressure between extractor and the withdrawing can, prevents that the interior air pressure of extractor from less than withdrawing can, causing reclaiming liquid from pouring in down a chimney to extractor in the withdrawing can.In order to improve the working efficiency of this device, conduit is provided with a formaldehyde steam flow extractor in the pneumatic pump help withdrawing can.It is that the discarded liquid of phenolic aldehyde has the small amounts of aldehyde compounds and together separates in separating formaldehyde as the reason that reclaims liquid that this device utilizes formaldehyde solution, if utilize distilled water as reclaiming liquid, the formaldehyde solution that reclaims can be low excessively because of purity, can not be used for industrial production.And use formaldehyde solution can improve the purity that reclaims back formaldehyde solution greatly as reclaiming liquid, can reach the needed purity of part industrial production.
Conduit be positioned at an end that reclaims under the liquid be provided with one pullover, have through hole on the pullover sidewall.The gas that enters withdrawing can by conduit forms tiny bubble when pullover, helps to improve the assimilated efficiency that reclaims liquid.
On withdrawing can, be provided with heat sink, can prevent that the recovery liquid in the withdrawing can from evaporating in a large number, cause reducing this device organic efficiency.Simultaneously conduit is provided with condenser, and formaldehyde steam is recovered liquid after the cooling during by condenser and absorbs.Heat sink and condenser can use water-cooled cooling.
Extractor and withdrawing can are provided with temperature measuring equipment, also can in extractor or withdrawing can temperature measuring equipment be set selectively, to make things convenient for the staff to detect and to control extractor and the temperature of recovery pot liquid.
The work of this device be utilize earlier vacuum pump with the air pressure in the extractor with 0.8 normal atmosphere about, utilize heating unit that the discarded liquid of resol is heated to 40 to 50 degrees centigrade then, and the temperature that keeps discarded liquid is at 40 to 50 degrees centigrade.Start pneumatic pump and flow to tourie by the gas in the extractor by conduit this moment, and gas flows back to extractor by the constant voltage jar through reclaiming after liquid absorbs.After 2 to 4 hours circular treatment, can obtain the higher aldehydes solution of purity in the extractor, withdrawing can then obtains the higher formaldehyde solution of purity.
The utility model possesses following products characteristics and advantage:
1. the resol of handling through device described in the utility model is discarded liquid and can be formed higher formaldehyde solution of purity and aldehydes solution, can recycling in industrial production;
2. the utlity model has the organic efficiency height, environmental pollution is low, reaches the requirement of " zero " discharging substantially;
3. the utility model is low to the processing cost of the discarded liquid of phenolic aldehyde, can be the processing cost that enterprise reduces a large amount of toxic wastes, and increases enterprise's productivity effect.
