Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 4, the circulating waste liquid recovery apparatus of one of the present utility model, comprises reboiler 10, recovery tower 20 and recycle pump 30, and recovery tower 20 to comprise at the bottom of tower body 21 and tower 22; Recycle pump 30 be communicated with by pipeline 40 and at the bottom of the top of reboiler 10 and tower 22 bottom between, the bottom of reboiler 10 by pipeline 40 with at the bottom of tower 22 top be communicated with; Be provided with some vapour pipes 11 in reboiler 10, tower body 21 inside is filled with ripple structured packing 23 and is provided with condenser.During work, tower body 21 toward recovery tower 20 passes into the waste liquid containing DMAC, the waste liquid of DMAC to flow at the bottom of the tower of recovery tower 20 22, then by recycle pump 30 by the bottom of tower 22 waste liquid extract in reboiler 10, waste liquid to flow at the bottom of tower 22 by pipeline 40 again in reboiler 10, namely under the effect of recycle pump 30, waste liquid can circulate between 22 at the bottom of reboiler 10 and tower, simultaneously, have steam in the vapour pipe 11 arranged in reboiler 10 constantly to pass into, whenever waste liquor stream through vapour pipe 11 time, waste liquid is when steam heating is issued to 100 DEG C, water evaporates in waste liquid becomes water vapor to lead to the tower body 21 of recovery tower 20 from pipeline 40, now, tower body 21 is full of the water vapor of high temperature, when vapour pipe 11 pairs of waste liquids are heated to 166 DEG C, DMAC solution evaporation in waste liquid becomes DMAC steam to continue to lead to from pipeline 40 tower body 21 of recovery tower 20, the waste liquid that DMAC steam can touch the lower water vapor of temperature and newly pass in tower body 21, DMAC steam is met cold, becomes DMAC solution stream and to be back at the bottom of tower 22, simultaneously, the waste liquid newly passed into is under the heat of DMAC steam, the moisture content wherein existed is evaporated again, circulation like this, DMAC solution can be accumulated and concentrate at the bottom of tower 22, regularly at the bottom of tower 22 DMAC carry out purity detecting, if conform with the regulations, reclaim, final realization is to the recovery of the DMAC solution in waste liquid.
Idiographic flow is as follows: ceaselessly pass into waste liquid toward tower body 21, waste liquor stream is through tower body 21, at the bottom of tower 22, under the effect of recycle pump 30, the vapour pipe 11 that waste liquid carries out between 22 and reboiler 10 circulating → arranging in reboiler 10 at the bottom of tower passes into steam, when the waste liquor stream circulated is in reboiler 10, steam in vapour pipe 11 can heat waste liquid → heating of the steam of waste liquid in vapour pipe 11 under, early stage is when reaching 100 DEG C, water evaporates in waste liquid goes out water vapor and enters to tower body 21, when the waste liquid steam heating continued in vapour pipe 11 is issued to more than 166 DEG C, DMAC solution evaporation in waste liquid goes out DMAC steam, DMAC steam enters to tower body 21 equally, the condenser arranged from tower body 21 under the DMAC vapor action of the high temperature more than 166 DEG C of the water vapor now in tower body 21 is isolated, simultaneously, the waste liquid newly passed into touches the DMAC steam of high temperature, moisture content in the waste liquid newly passed into is evaporated equally, and then the device that is condensed isolate → the DMAC steam of high temperature touches the waste liquid newly passed into and is condensed into DMAC solution aggregation at the bottom of tower 22, when at the bottom of tower, the 22 DMAC solution purity assembled do not reach standard, continue to enter under the effect of recycle pump 30 in reboiler 10 to carry out evaporating → so circulating, when the purity conformance with standard of the 22 DMAC solution assembled at the bottom of tower finally being detected, recycling can be carried out.
Retrieving arrangement of the present utility model is equally applicable to sweet oil recovery.Wherein, ripple structured packing 23 porosity is high, and the resistance of fluid is little, and waste liquor stream can distribute very equably when ripple structured packing 23, increases the contact area of waste liquid and DMAC steam and improves heat exchanger effectiveness; The setting of the vapour pipe 11 of some can increase the total surface-area of vapour pipe 11, and then increases the contact area of vapour pipe 11 and mobile waste liquid.
In the present embodiment, described tower body 21 saves 24 by some joint tower bodies and assembles, can set up more piece tower body joint 24 during production as required or reduce tower body joint 24, selecting most suitable tower body 21 highly to meet the needs of production, assurance device investment can not cause waste.Concrete, the quantity of described tower body joint 24 is five joints, and tower bodies 21 height that five joint tower bodies joints 24 assemble can meet and carries out the recovery of DMAC solution to a large amount of waste liquids, can guarantee that organic efficiency is high simultaneously, effective.
More specifically, the quantity of described vapour pipe 11 is 106,106 vapour pipes 11 are fixed together by the pull bar 12 that four are evenly arranged, between vapour pipe 11, there is certain spacing, vapour pipe 11 total surface area formed is very large, and can ensure that the surface of vapour pipe 11 fully contacts with the waste liquid flowed through in reboiler 10, the steam fully realized in vapour pipe 11 carries out heating evaporation to waste liquid, reasonable in design, practical.
In the present embodiment, the top of described tower body 21 offers waste liquid admission port 25, the waste liquid offered enters mouth for connecting waste liquid output pipe, guarantee that waste liquid passes in tower body 21 effectively, and then waste liquid to enter at the bottom of tower 22, then under the effect of recycle pump 30 waste liquid at the bottom of tower 22 and reboiler 10 in circulate.
Ripple structured packing 23 can select stainless steel wave line structured packing, ceramic ripple structured packing etc., in the present embodiment, preferred ripple structured packing 23 is stainless steel ripple structured packing, and the flux of the relative other materials of the ripple structured packing 23 adopting stainless material to make is larger, resistance is less, cost is lower, anti-clogging is better.
Known the utility model is have above-described good characteristic in sum, is made it on using and manufacturing, and promotes in conventional art the usefulness that do not have and has practicality, becoming the novel product structure that has practical value.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
