Description
Technical field
The invention belongs to chemical industry equipment.Especially relate to a kind of coking chemical waste water immersed blow desorber.
Background technology
Coking chemical waste water is main source with the remained ammonia mainly, and its flow is big, the ammonia-nitrogen content height.At present, both at home and abroad the coke-oven plant all adopts ammonia still to steam ammonia nitrogen in the remained ammonia, and ammonia still is divided into two kinds of bubble-cap formula and screen formulas.Bubble-cap formula ammonia still divides two sections, connect with flange, in establish 25 layers of tower tray, 5 layers of epimeres and shell are made with the titanium material, 20 layers of hypomeres and shell are made with low charcoal stainless steel, dephlegmator is placed on the ammonia still top, is the part of ammonia still; Screen formula ammonia still has the strip grate seam on column plate, no downtake, and grid seam percentage of open area is 15%～25%, and the screen number of plies is generally 32 layers, and screen and tower shell are cylinder iron made, and the vapour-liquid two phase countercurrent flow passes screen, keeps running balance.In remained ammonia ammonia distillation process flow process, raw material ammonia water enters from ammonia still top, and tower bottom feeding steam steams the volatilization ammonia in the ammoniacal liquor, and ammonia steam is overflowed from cat head after the dephlegmator condensation, and distilled ammonia wastewater flows out from the tower bottom outlet.Adopt this ammonia still to remove ammonia nitrogen in the remained ammonia, not only equipment is big, and ammonia nitrogen removal efficient is low, and causing the biochemical treatment load big, processed waste water does not reach discharging standards, and 1 ton of waste water need use 160～200 kg water steam in the ammonia still process process, the cost height, power consumption is big.
Summary of the invention
The purpose of this invention is to provide that a kind of equipment is little, production cost is low, less energy consumption, ammonia nitrogen removal efficient height, immersed blow desorber that the biochemical treatment ammonia nitrogen loading is little.
For achieving the above object, the technical solution used in the present invention is: this stripping desorption device is fixedly connected by immersed type stripping device and condensation refrigerating unit two portions and forms; The top of immersed type stripping device inwall is installed with the remained ammonia sparger, and the distributed pipeline of remained ammonia sparger communicates with the liquid inlet that is arranged on immersed type stripping device top; Be installed with one section gas distributor under the middle part liquid level of immersed type stripping device inwall, the distributed pipeline of one section gas distributor communicates with gas entry on being arranged on immersed type stripping device; Be installed with two sections gas distributors on the bottom top of immersed type stripping device, the distributed pipeline of two sections gas distributors communicates with gas entry on being arranged on immersed type stripping device; Side between immersed type stripping bottom of device and two sections gas distributors is provided with liquid exit, and liquid exit top is equipped with traverse baffle, at the opposite side of immersed type stripping device the liquid level meter is installed; Be provided with prolong in the condensation refrigerating unit, the top of condensation refrigerating unit is provided with pneumatic outlet.Wherein:
The remained ammonia sparger is a ring pipe, is provided with 3～20 spray orifices or nozzle below the installation site of ring pipe.
One section gas distributor, two sections gas distributors are ring-like shape pipe, and ring pipe is provided with 3～100 spray orifices, and the pipeline of ring pipe directly communicates or communicates by 2～5 pipe influx with gas entry or by a pipeline.
The cross section of traverse baffle is for falling " L " shape, falls leveling board of " L " shape and the inwall that vertical panel all is fixed on immersed type stripping device.
Owing to adopt technique scheme, the present invention has that equipment is little, production cost is low, less energy consumption, ammonia nitrogen removal efficient height, characteristics that the biochemical treatment ammonia nitrogen loading is little.
