Description
Изобретение относитс к области очистки промывных вод производства ацетилена.This invention relates to the purification of wash water for the production of acetylene.
Известный способ очистки промывных вод производства ацетилена заключаетс в обработке их сол ми железа (вводимыми в количестве 5-10 мг/л) и полиакриламидом с последующим отстаиванием.A known method for purifying the wash water from the production of acetylene is to treat them with iron salts (entered in an amount of 5-10 mg / l) and polyacrylamide, followed by settling.
Недостатком известного способа вл етс низка степень очнстки промывных вод (качество осветлени составл ет 200-500 мг/л), цементаци твердой взвеси карбоната кальци на поверхности трубонроводов и коммуникаций , а также значительные потери ацетилена со шламом.The disadvantage of this method is the low degree of wash water (the quality of clarification is 200-500 mg / l), the cementing of a solid suspension of calcium carbonate on the surface of pipelines and communications, as well as significant losses of acetylene with sludge.
Предложенный способ отличаетс от известного применением соли железа в количестве 0,5-0,8 мг/л, а полиакриламида 0,05- 0,1 мг/л. Это повышает степень очистки: качество осветлени составл ет О-20 мг/л (по известному способу 200-500 мг/л), предотвращает цементацию твердой взвеси на поверхност х коммуникаций и трубопроводов, дает возможность получать шлам в виде более плотных агрегатов, который в силу этого легко отдел етс от воды (что сокращает потери ацетилена со шламом). Концентраци в зоне отборных шламов увеличиваетс до 470 г/л в предложенном способе (по известному способу 380 г/л). Количество необходимых дл очистки реагентов па пор док уменьшаетс , что зпачительно удешевл ет процесс. Пример. Па осветление подают промывные воды Карагандинского завода синтетического каучука в количестве 200 , имеющие следующий состав (в мг/л):The proposed method differs from that known by using an iron salt in the amount of 0.5-0.8 mg / l, and polyacrylamide 0.05-0.1 mg / l. This increases the degree of purification: the quality of clarification is O-20 mg / l (by a known method 200-500 mg / l), prevents the cementation of a solid suspension on the surfaces of communications and pipelines, makes it possible to obtain sludge in the form of denser aggregates the strength of this is easily separated from water (which reduces the loss of acetylene with sludge). The concentration in the zone of selected sludges is increased to 470 g / l in the proposed method (380 g / l by a known method). The amount of reagents required for cleaning is reduced, which reduces the cost of the process. Example. Pa clarification serves the wash water of the Karaganda synthetic rubber plant in an amount of 200, having the following composition (in mg / l):
Са2+(СаО)--1000Ca2 + (CaO) - 1000
Mg4-(MgO)-0,36Mg4- (MgO) -0.36
РеН(Ре2Оз),22PeH (Pe2Oz), 22
А1з+(А12Оз)-0,64A1z + (A12Oz) -0.64
Количество взвешенных веществ в промывных водах В очищаемую воду ввод т 0,5-0,8 мг/л FeCls и 0,05-0,1 мг/л полнакриламида и затем воду направл ют в отстойник Дорра дл осветлени .The amount of suspended matter in the wash water. 0.5-0.8 mg / l FeCls and 0.05-0.1 mg / l polnacrylamide are injected into the water to be purified, and then the water is sent to the Dorr sump for clarification.
