Description
(54) СПОСОБ УПРАВЛЕНИЯ .ПРОЦЕССОМ ТЕРМИЧЕСКОГО ОПРЕСНЕНИЯ(54) METHOD OF MANAGING THE PROCESS OF THERMAL DESPINEMENT
Изобретение относитс к управле НИН) многокорпусными выпарными опресвитальными установками. Оно может. быть использовано дл выпаривани морской воды дл питьевого и про «лаленно-коз йственного водоснабжени , дл протитки парогенераторов ТЭС и ABCj, дл очистки загр зненных вод, а также дл глубокого упариваний морских вод с целью извлечени минерсшьных солей.FIELD OF THE INVENTION The invention relates to the control of NIN) multiple-effect evaporator down-pressure plants. It can. to be used for evaporation of seawater for drinking and pro- duction of lazy-goat water supply, for cleaning steam generators of TPPs and ABCj, for purifying polluted waters, as well as for deep evaporation of seawater for the purpose of extracting salt salts.
Известен способ управлени процессом термического опреснени в многокорпусной опреснительной установки, осуществл емый изменени подачи греющего пара по те мпературе раствора в выпарном аппарате с коррекцией по плотности и расходу исходного раствора 1.A known method of controlling the process of thermal desalination in a multi-unit desalination plant, carried out by varying the supply of heating steam by the temperature of the solution in the evaporator with a correction for the density and flow rate of the initial solution 1.
Наиболее близким по технической сущности к предложенному вл етс способ управлени процессом опреснени , в котором осуществл ют воздействие наподачу греюгаего пара по разности изме)енного давлени вторичного пара и максимально допустимого давлени , определ емого измеренной концентрацией солей исходного упариваемогЬ раствора 2,The closest in technical essence to the proposed is a method of controlling the desalination process, in which the impact of the heating pair is influenced by the difference in the measured pressure of the secondary steam and the maximum allowable pressure determined by the measured salt concentration of the initial evaporated solution 2,
Однако в известном способе повышение производительности установки по ДИСТИЛЛЯТУ приводит к увеличению удельного .расхода тепла.However, in the known method, an increase in the productivity of the installation according to the DISTILLATE leads to an increase in the specific heat consumption.
Цель насто щего изобретени - снижение себестоимости дистилл та за счет повышени производв1тельности установки, по дистилл ту.The purpose of the present invention is to reduce the cost of a distillate by increasing the production capacity of the plant, according to the distillate.
Дл этого измер ют расходы тепла, To do this, measure the costs of heat,
10 морской воды, электроэнергии, умножают измеренные величины на весовые коэффициенты и вычисл ют отнсндение суммы полученных величин к измеренной производительности установки по 10 sea water, electricity, multiply the measured values by weights and calculate the relative value of the obtained values to the measured installation capacity by
15 дистилл ту. Путем воздействи на расход греющего пара уменьшают полученное отнощение так, чтобы давление вторичных паров в сепараторе первого корпуса не превысило допустимого 15 distillate that. By acting on the flow rate of heating steam, the ratio obtained is reduced so that the pressure of the secondary vapors in the separator of the first body does not exceed the allowable
