Description

Известен периодический способ получени  силиката свинца взаимодействием водных растворов нитрата свинца и силиката натри  прк температуре около 100. Однако получаемый этим способом силикат свинца, вследствие изменени  условий осаждени , что неизбежно в периодическом процессе, имеет непосто нные физико-химические свойства, что отрицательно сказываетс  при его дальнейшем использовании.The known periodic method of producing lead silicate by reacting aqueous solutions of lead nitrate and sodium silicate at a temperature of about 100. However, lead silicate obtained by this method, due to a change in deposition conditions, which is unavoidable in a batch process, has unstable physicochemical properties, which negatively affects its further use.

Предлагаемый непрерывный способ осаждени  силиката свинца с автоматическим регулированием позвол ет получать легкофильтруюи 1ийс  продукт, обладающий посто нными физико-химическими свойствами . Сущность предлагаемого способа заключаетс  во взаимодействии водных растворов нитрата свинца и силиката натри  при температуре 90-99° и значени х рН от 6,2 до 7,2. При это.м исходные растворы ниграта свинца и силиката натри  неирерывно и одновременно подаюг в реактор-осадитель с интенсивно перемещиваемой суспензией силиката свинца. Часть суспензии, соответствующей подаче исходных реагентов, скоростью непрерывно удал ют из реактора через переливную трубу на фильтрацию, промывку и сушку. Заданна  производительность и среднее выбранное врем  пребывани  частиц осадка силиката свинца в реакторе сохран ютс  посто нными за счет посто нной скорости п .;дачи раствора силиката натри , что обеспечивают посто нным нанором раствора и соответствующей диафрагмой, установленной на питающе.м трубопроводе. Регулирование значени  рН в пределах заданных значений обеспечивают подачей раствора нитрата серебра через клапан, управл елп 1Й регулирующим рН-метром, а автоматическое регулирование температуры суспензии осуществл ют при помощи известных регул торов температуры.The proposed continuous process for the deposition of lead silicate with automatic control makes it possible to obtain a light-filtered and 1st-product with constant physicochemical properties. The essence of the proposed method consists in the interaction of aqueous solutions of lead nitrate and sodium silicate at a temperature of 90-99 ° C and pH values from 6.2 to 7.2. At that, the initial solutions of nigrate of lead and sodium silicate non-intermittently and simultaneously feed into a precipitating reactor with a rapidly moving suspension of lead silicate. A part of the suspension, which corresponds to the supply of initial reagents, is continuously removed from the reactor through an overflow pipe for filtration, washing and drying. The specified capacity and the average selected residence time of the lead silicate precipitate particles in the reactor are kept constant due to the constant speed of the solution, the sodium silicate solution, which is provided by a constant solution nanometer and corresponding diaphragm installed on the supply pipe. The adjustment of the pH value within the prescribed values is ensured by the supply of silver nitrate solution through the valve, controlled by a pH meter, and the automatic control of the temperature of the suspension is carried out using known temperature regulators.
