Description
По существующей на заводах схеме процесс извлечени св занного аммиака заключаетс в разрушении солей аммони известью Полученный аммиак далее поступает в сульфатное отделение, где образуетс тот же продукт - сульфат аммони .According to the existing scheme of the plants, the recovery of bound ammonia consists in the destruction of ammonium salts by lime. The resulting ammonia then goes to the sulphate compartment, where the same product is formed - ammonium sulphate.
Предлагаемый способ переработки надсмольных вод коксохимических заводов при полупр мом процессе получени сульфата аммони отличаетс тем, что надсмольные воды выпаривают до концентрации солей, позвол ющей в сатураторах проводить кристаллизацию совместно с сол ми, образующимис из аммиака коксового газа. При этом упрощаетс процесс переработки надсмольных вод; так как: ликвидируютс известковое отделение с отстойником, приколонками и известковым реактором; устран ютс трудности, св занные с изготовлением известкового раствора; отпадает необходимость в чистке известковых приколонков от гипса и отстойников от шлама, уменьщаетс содержание агрессивных веществ в сточной воде, идущей дл тушени кокса, что удлинит срок службы аппаратуры коксового цеха, и создаетс возможность полной автоматизации работы аммиачного отделени , что невозможно было осуществить при работе известкового отделени .The proposed method for processing the coarse-tar water of coke plants during the semi-direct ammonium sulphate production process is characterized in that the over-resin water is evaporated to a concentration of salts, which allow crystallization to occur in the saturators together with the coke oven gas ammonia. This simplifies the processing of supra-resin water; because: the lime compartment with the settling tank, jokes and lime reactor is being disposed of; eliminates the difficulties associated with the manufacture of lime mortar; there is no need to clean lime limestones from gypsum and sedimentation tanks from sludge, the content of corrosive substances in wastewater used to extinguish coke is reduced, which will prolong the service life of the equipment of the coke workshop, and the ammonia separation can be fully automated. branches.
Способ может быть осуществлен по схеме, изображенной на чертеже , включающей испарительные колонны / и 2, промежуточные сборники 3 дл аммиачной воды, скрубер дл обесфеноливани 4, выпарные аппараты 5, сборник 6, дл упаривани аммиачной воды, сборник конденсата 7, подогреватель аммиачной воды 8.The method can be carried out according to the scheme shown in the drawing, including evaporation columns I and 2, intermediate collectors 3 for ammonia water, scrubber for dephenolization 4, evaporators 5, collector 6, for evaporation of ammonia water, condensate collector 7, ammonia heater 8 .
Воду газосборникового цикла (50% избытка) подают на испарительную колонну / и затем направл ют на дальнейшую переработку . Другую часть избытка (50%) надсмольной воды в виде конденсата первичных газов холодильников направл ют на вторую испариWater from the gas collector cycle (50% excess) is fed to the flash column / and then sent for further processing. Another part of the excess (50%) of the over-resin water in the form of condensate of the primary gases of the coolers is sent to the second vapor
