\n\tThe recirculating chiller is a supporting
\ndistillation equipment, which separates different mixtures by vaporizing and
\ncondensing multiple times. It can be used well with the distillation equipment,
\nwhich can not only improve its operating efficiency, but also save energy.<\/span>\n<\/p>\n

\n\t\"\"<\/p>\n

\n\tIn the normal operation of the
\nrectification equipment, the product quality index must meet the predetermined
\nrequirements, that is, to ensure that the purity of at least one component in
\nthe product meets the specified requirements, and the other components should
\nalso be kept within the specified range. Therefore, it should be Take the
\npurity of the bottom of the device or the top of the device as the controlled
\nvariable. However, online real-time monitoring of product purity has certain
\ndifficulties. Therefore, in most cases, the “temperature and
\npressure” in the rectification device are used to indirectly reflect the
\nproduct purity.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tThe direct quality index of the heating
\nconstant temperature tank for the distillation equipment is the product
\ncomponent, but the product component analysis cycle is long and the lag is
\nserious, so the temperature parameter has become a commonly used control index,
\nthat is, controlled by the sensitive board.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tThe adjustment method of the recirculating
\nchiller for the distillation equipment is to appropriately adjust the reflux
\nratio according to the temperature of the sensitive plate. For example, when
\nthe temperature of the sensitive plate rises, it reflects that the XD of the
\ntop product composition of the device has decreased. Therefore, at this time, a
\nsignal is sent to appropriately increase the reflux ratio, so that when XD
\nrises to a qualified value, the temperature of the sensitive plate drops to the
\nspecified value.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tWhen the boiling points of the components
\nin the raw material liquid are similar, and the purity requirements of the
\nproduct are higher, it is not appropriate to use the general temperature
\ncontrol method, but to use the temperature difference control method. The
\ntemperature difference control is designed based on the principle that the
\ntemperature change of the two plates is always relatively larger than the
\ntemperature change range of a single plate. This method is easy to ensure the
\npurity of the product, and it is also conducive to the choice and use of the
\ninstrument.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tThe recirculating chiller for the
\ndistillation equipment is the core component of the chemical process equipment,
\nand the temperature control is the top priority for the rectification equipment
\ncontrol. The drastic changes in temperature will cause the purity of the
\nseparated components to decrease, which will affect the efficiency of the
\nrectification. The impact is large, and even causes the rectification unit to
\nfail to operate normally. The temperature control system creates good
\nconditions for the normal operation of the rectification unit. As the degree of
\nautomation increases, the operation of the rectification device should also be
\ncontrolled by instrument automation, so that the quality of the product and the
\nstability of the operation of the rectification device are greatly improved.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tOf course, the recirculating chiller can
\nalso be used with other reaction equipment. In the pharmaceutical and chemical
\nindustry, many temperature control fields need to be used to control the
\ntemperature.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
