The invention discloses a phenolic wastewater filler stripper plant which comprises a stripping column and a heat exchanger, wherein the stripping column comprises a cylinder and a filler and is provided with a stripping section, a first regeneration section and a second regeneration section; a spray device is respectively arranged above the filler of each section; the heat exchanger is arranged outside the stripping column; a hot fluid outlet of the heat exchanger is communicated with the spray device above the stripping section; the top of the stripping column is provided with a circulating steam pipeline which is communicated with the bottom of the second regeneration section; a spray pipeline between the stripping section and first regeneration section is connected with a new alkali liquor inlet pipeline; the bottom of the stripping section is connected with a water outlet pipeline; and the water outlet pipeline is connected with a hot fluid inlet of the heat exchanger; and a spray pipeline between the first regeneration section and second regeneration section is connected with a circulating alkali liquor inlet pipeline. The phenolic wastewater filler stripper plant has the advantages of simple technique, lower equipment cost and high treatment efficiency, can reach economic balance of income and outlay when being used for treating high-concentration (1g/L above) phenolic wastewater, and can not generate secondary pollution.
Description
Technical field
The present invention relates to a kind of waste disposal plant, be specifically related to a kind of phenolic wastewater filler stripper plant.
Background technology
Vaporizing extract process is that sewage directly contacts with water vapour, the volatile matter in sewage is diffused in gas phase by a certain percentage, thus reaches the object of separating contaminants from sewage.The process of the phenolic wastewater that our company produces is technological difficulties always, and be all the treatment process adopting adding medicine in the past, processing efficiency is low, complex treatment process.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above, and provide a kind of phenolic wastewater filler stripper plant, processing efficiency is high, and technique is simple.
The technical scheme solved the problems of the technologies described above is as follows:
Phenolic wastewater filler stripper plant, comprise stripping tower body and interchanger, the filler that described stripping tower body comprises a cylindrical shell and is arranged in cylindrical shell, described filler is three sections, be respectively stripping stage from top to bottom, first RS Regenerator Section and the second RS Regenerator Section, the top of every section of described filler is provided with spray equipment, described interchanger is arranged on the outside of stripping tower body, spray equipment above the hot fluid outlet ports of described interchanger and stripping stage passes through pipeline communication, the top of described stripping tower body is provided with a cyclic steam pipeline and communicates with the bottom of the second RS Regenerator Section, spray piping between stripping stage with the first RS Regenerator Section is connected with new alkali lye inlet pipeline, an outlet conduit is connected bottom stripping stage, this outlet conduit is connected with the hot-fluid import of interchanger, spray piping between first RS Regenerator Section with the second RS Regenerator Section is connected with circulation alkali liquor inlet pipeline, interchanger is also provided with phenolic wastewater import and dephenolize wastewater outlet.
Described filler is structured packing.
The bottom of described stripping tower body is also provided with live steam inlet pipeline and sodium phenolate outlet conduit.
Present invention process is simple, and equipment cost is lower, and processing efficiency is high, and process high density (more than 1g/L) phenolic wastewater, can reach balance between revenue and expenditure economically, and can not produce secondary pollution.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
