Abstract
The invention discloses a device and working method for comprehensively utilizing factory waste heat for fractionation drying and power generation. The device includes: an organic Rankine cycle system, a fractionation system, a drying system and a second-type absorption heat pump system. The invention utilizes the second type of absorption heat pump to convert waste heat generated by devices such as atmospheric and vacuum, catalytic cracking, and delayed coking into high-temperature steam, and then feeds it into a reboiler to drive a fractionation tower to complete fractionation. The waste heat generated by the top material of the fractionation tower and the condensation heat generated by the reboiler drive the organic Rankine cycle to generate electricity and then supply the drying chamber to dry sludge or catalyst, realizing the cascade utilization of waste heat, reducing energy waste and protecting the environment.
Description
Technical field[0001]The present invention relates to an apparatus for fractionation drying and power generation by a combination of a plant, and a second type of absorbent heat pump system, a fractionation system, an organic lacing system, and a drying system, and the recovery heat heat will be used. It belongs to the field of energy utilization.Background technique[0002]In the production process, refining companies inevitably produce a lot of waste heat. The low temperature waste heat of refining enterprises is mainly distributed in a normal reduction distillation, catalytic cracking, delay coking, and the three parts of low temperature waste account for about 60% to 80% of the total amount of low temperature waste heat. The low temperature waste heat that is not utilized during the production will eventually discharge it into the environment in various forms, which is mainly discharged, which is mainly discharged by the following four ways: air-cooler discovement, intermediate pr...
