所述的第一蜡油-贫液换热器14与第九阀门10的连接管路上分支出一安装有第十阀门11的管路。 A pipeline equipped with a tenth valve 11 is branched from the pipeline connecting the first wax oil-lean liquid heat exchanger 14 and the ninth valve 10 .
工作原理如下： It works as follows:
投用焦化蜡油给胺液再生塔底第一蜡油-贫液换热器14提供热源时，第二阀门2、第四阀门4、第七阀门7、第十阀门11关闭。 When coking wax oil is used to provide a heat source for the first wax oil-lean liquid heat exchanger 14 at the bottom of the amine regeneration tower, the second valve 2, the fourth valve 4, the seventh valve 7, and the tenth valve 11 are closed.
自焦化分馏塔来的蜡油首先经过第一阀门1、第六阀门6进入第一蜡油-贫液换热器14的管程与自胺液再生塔底13来的贫液换热，换热后的蜡油经过第九阀门10、三通阀9、第八阀门8、第三阀门3返回到蜡油去水槽12，换热后的贫液自第一蜡油-贫液换热器14的壳程返回到胺液再生塔13。 The wax oil from the coking fractionation tower first passes through the first valve 1 and the sixth valve 6 and enters the tube side of the first wax oil-lean liquid heat exchanger 14 to exchange heat with the lean liquid from the bottom 13 of the amine regeneration tower. The heated wax oil returns to the wax oil water tank 12 through the ninth valve 10, the three-way valve 9, the eighth valve 8, and the third valve 3, and the lean liquid after heat exchange flows from the first wax oil-lean liquid heat exchanger The shell side of 14 returns to the amine liquid regeneration tower 13.
在蜡油给第一蜡油-贫液换热器14提供热源的同时，为了防止乙醇胺因为温度过高而分解，设计焦化来的蜡油经过第五阀门5、三通阀9后与换热后的蜡油混合，混合后的蜡油返回到蜡油去水槽。当第一蜡油-贫液换热器14壳程出口的贫液温度高时，关小三通阀9，使流过第五阀门5的蜡油增多，流过第六阀门6的蜡油减少，否则与之相反。 While the wax oil provides the heat source for the first wax oil-lean liquid heat exchanger 14, in order to prevent ethanolamine from decomposing due to high temperature, the coked wax oil is designed to exchange heat with the fifth valve 5 and the three-way valve 9 After the wax oil is mixed, the mixed wax oil is returned to the wax oil tank. When the temperature of the lean liquid at the shell side outlet of the first wax oil-lean liquid heat exchanger 14 is high, close the three-way valve 9 to increase the wax oil flowing through the fifth valve 5 and decrease the wax oil flowing through the sixth valve 6 , otherwise the opposite.
当需要切除换热器维修时，只需关闭第五阀门5、第六阀门6、第九阀门10、第七阀门7，打开第四阀门4即可。 When it is necessary to remove the heat exchanger for maintenance, it is only necessary to close the fifth valve 5, the sixth valve 6, the ninth valve 10, and the seventh valve 7, and open the fourth valve 4 to get final product.
当三通阀9需要维修时，只需打开第七阀门7，关闭第五阀门5、第九阀门10、第八阀门8，用第四阀门4调节经过第一蜡油-贫液换热器14的流量。 When the three-way valve 9 needs maintenance, it is only necessary to open the seventh valve 7, close the fifth valve 5, the ninth valve 10, and the eighth valve 8, and use the fourth valve 4 to adjust the first wax oil-lean liquid heat exchanger 14 traffic.
当三通阀9、第一蜡油-贫液换热器14同时需要维修时，只需打开第二阀门2，关闭第一阀门1、第三阀门3，由蒸汽给第二蜡油-贫液换热器15提供热源。 When the three-way valve 9 and the first wax oil-lean liquid heat exchanger 14 need maintenance at the same time, only the second valve 2 needs to be opened, the first valve 1 and the third valve 3 should be closed, and the second wax oil-lean liquid heat exchanger 14 needs to be repaired by steam. A liquid heat exchanger 15 provides the heat source.
本实用新型将焦化蜡油蒸汽发生器出来的蜡油引到胺液再生塔底第一蜡油-贫液换热器14，给塔底贫液换热后去水槽降温，充分利用了蜡油的高位热源，降低了胺液再生塔的能耗。 The utility model leads the wax oil from the coking wax oil steam generator to the first wax oil-poor liquid heat exchanger 14 at the bottom of the amine liquid regeneration tower, exchanges heat for the lean liquid at the bottom of the tower, and then goes to the water tank to cool down, making full use of the wax oil The high-level heat source reduces the energy consumption of the amine liquid regeneration tower.
