Detailed description of the invention
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.
As shown in Figure 1, the utility model is achieved in that a kind of coking plant and amine liquid regenerating unit heat exchange network optimization system comprise the first valve 1, second valve 2, the 3rd valve 3, the 4th valve 4, the 5th valve 5, the 6th valve 6, the 7th valve 7, the 8th valve 8, triple valve 9, the 9th valve 10, the tenth valve 11, wax oil anhydrate groove 12, amine liquid regenerator 13, the first wax oil-lean solution heat exchanger 14, the second wax oil-lean solution heat exchanger 15;
Described amine liquid regenerator 13 is connected with the first wax oil-lean solution heat exchanger 14, the second wax oil-lean solution heat exchanger 15 by pipeline;
The first described valve 1, second valve 2, the 3rd valve 3 are arranged on described wax oil and anhydrate on groove 12, and the second valve 2 is arranged between the first valve 1 and the 3rd valve 3;
The first described valve 1, the 6th valve 6 sequentially pass through pipeline and are connected with the first described wax oil-lean solution heat exchanger 14;
The 9th described valve 10, triple valve 9, the 8th valve 8, the 3rd valve 3 sequentially pass through pipeline and are connected with the first described wax oil-lean solution heat exchanger 14;
Connecting pipe top set between the first described valve 1 and the 6th valve 6 goes out the pipeline that is provided with the 4th valve 4, and this pipeline is connected with the pipeline being connected the 8th valve 8 and the 3rd valve 3;
Connecting pipe top set between the first described valve 1 and the 6th valve 6 goes out the pipeline that is provided with the 5th valve 5, and this pipeline is connected with triple valve 9;
The connecting line top set of the first described wax oil-lean solution heat exchanger 14 and the 9th valve 10 goes out the pipeline that is provided with the 7th valve 7, and this pipeline is connected with the pipeline being connected the 8th valve 8 and the 3rd valve 3;
The connecting line top set of the first described wax oil-lean solution heat exchanger 14 and the 9th valve 10 goes out the pipeline that is provided with the tenth valve 11.
Operation principle is as follows:
When the wax tailings that comes into operation provides thermal source to the first wax oil-lean solution heat exchanger 14 at the bottom of amine liquid regenerator, the second valve 2, the 4th valve 4, the 7th valve 7, the tenth valve 11 are closed.
First the wax oil come from coking fractional distillation column enters the first wax oil-lean solution heat exchanger 14 tube side through the first valve 1, the 6th valve 6 with at the bottom of amine liquid regenerator 13 lean solution heat exchange, wax oil after heat exchange turns back to wax oil through the 9th valve 10, triple valve 9, the 8th valve 8, the 3rd valve 3 and to anhydrate groove 12, and the lean solution after heat exchange turns back to amine liquid regenerator 13 from the shell side of the first wax oil-lean solution heat exchanger 14.
Give while the first wax oil-lean solution heat exchanger 14 provides thermal source at wax oil, decompose because temperature is too high to prevent monoethanolamine, the wax oil that design coking comes mixes with the wax oil after heat exchange after the 5th valve 5, triple valve 9, and mixed wax oil turns back to wax oil and to anhydrate groove.When the lean solution temperature height of the first wax oil-lean solution heat exchanger 14 shell-side outlet, turn down triple valve 9, the wax oil flowing through the 5th valve 5 is increased, the wax oil flowing through the 6th valve 6 reduces, otherwise in contrast.
When needs excision heat exchanger maintenance, only need close the 5th valve 5, the 6th valve 6, the 9th valve 10, the 7th valve 7, open the 4th valve 4.
