Description

Изобретение относитс  к тепломассообменной аппаратуре и может быть использовано в энергетической промышленности.The invention relates to heat and mass transfer apparatus and can be used in the energy industry.

Известен способ работы кожухотрубного теплообменника путем регулировани  4)асхода теплоносител  и ввода газа в его поток.The known method of operation of a shell-and-tube heat exchanger is by adjusting 4) the flow rate of the heat transfer medium and the introduction of gas into its flow.

Недостатком указанного способа  вл етс  наличие колебаний тепломассообменных труб, что приводит к нарушению герметичности и снижению надежности теплообменника в целом.The disadvantage of this method is the presence of oscillations of heat and mass transfer pipes, which leads to a breach of tightness and reduce the reliability of the heat exchanger as a whole.

Цель изобретени  - обеспечение гашени  колебаний tpy6.The purpose of the invention is to provide suppression of tpy6 oscillations.

Указанна  цель достигаетс  тем, что расход газа поддерживают 4-8% от объемного расхода теплоносител .This goal is achieved by the fact that the gas flow rate supports 4-8% of the volumetric flow rate of the coolant.

Наличие в жидком теплоносителе гйзовой фазы существенно измен ет характер обтекани  труб, а именно измен ет упругиеThe presence of the fluid phase in the liquid coolant significantly changes the flow pattern of the pipes, namely, it changes the elastic

Совокупность указанных факторов при расходе газа 4-8% от объемного расхода теплоносител  приводит к исчезновению колебаний труб,The combination of these factors at a gas flow rate of 4-8% of the volumetric flow of the coolant leads to the disappearance of pipe oscillations, Уменьшение расхода газа до ниже 4% или увеличение расхода до выше 8% от объ0 емного расхода теплоносител  гфиводит к возникновению колебаний в отдельных трубах и, с увеличением отклонени  расхода оптимального предела, колебани  теплообменных труб возрастают.A decrease in gas consumption to below 4% or an increase in consumption to above 8% of the volumetric flow rate of the coolant leads to oscillations in individual pipes and, with an increase in the deviation of the flow rate of the optimal limit, the oscillations of the heat exchange pipes increase. 5five Регулирование расхода газа в указанных пределах обеспечивает гашение колебаний труб и повышает надежность теплообменника в целом.Regulation of gas flow within the specified limits provides damping of pipe vibrations and increases the reliability of the heat exchanger as a whole. 00 (56) Авторское свидетельство СССР N 661225, кл.
