Abstract
The utility model discloses a device utilizing residual heat to heat coal tar, which includes a heating oil pipeline (1) and tar pipelines (2), as well as a tar-fuel oil heat exchanger (3), wherein the heating oil pipeline (1) is connected with the tube side of the tar-fuel oil heat exchanger (3); and the tar pipelines (2) are connected with the shell side of the tar-fuel oil heat exchanger (3). In the utility model, through the arrangement of the tar-fuel oil heat exchanger, heating oil about 160 DEG C flowing out from a stirring chest firstly exchanges heat with tar about 80 DEG C entering a first section pump; the original first section tower-entering process is conducted with the tar after being subjected to heat exchange, and the heating oil enters a heating oil groove, so that on the one hand, residual heat of the heating oil is utilized, and the heat loss is reduced, and on the other hand, the temperature of the tar after heat exchange can be increased by 10 DEG C, thereby saving vapor cost about 34 thousand yuan per month, and reducing the manufacturing cost.
Description
Technical field
The utility model relates to a kind of device that utilizes waste heat to the coal tar heating.
Background technology
The temperature of coal tar before going into tower is about 80 ℃, needs to heat with steam, and this kind arts demand uses a large amount of steam, has increased production cost.And meanwhile, the oil fuel about 160 ℃ directly gets in the fuel oil groove, causes the waste of energy.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, provides a kind of waste heat to oil fuel to utilize the device that coal tar is heated.
Technical scheme: the described device that utilizes waste heat to the coal tar heating of the utility model; Comprise oil fuel pipeline, tar pipeline and tar-usual heat-exchanger; Said oil fuel pipeline is connected with the tube side of said tar-usual heat-exchanger through the pipe of ￠ 108, and said tar pipeline is connected with the shell side of said tar-usual heat-exchanger through the pipe of ￠ 133.
Beneficial effect: the utility model compared with prior art; Its beneficial effect is: the utility model is through being provided with tar-usual heat-exchanger; Let about 160 ℃ oil fuel from steel basin come out the back earlier with about 80 ℃ the tar heat exchange that gets into one section pump, the tar after the heat exchange gets into former one section again and goes into the tower flow process, oil fuel gets into the fuel oil groove; Utilize the waste heat of oil fuel on the one hand, reduced calorific loss; The tar temperature can improve 10 ℃ after the heat exchange on the other hand, thereby practices thrift about 3.4 ten thousand/moon of steam cost, has reduced production cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in Figure 1; The said device that utilizes waste heat to the coal tar heating of the utility model; Comprise oil fuel pipeline 1 and tar pipeline 2, utilize an original light oil water cooler (heat interchanging area 75M2) as tar-usual heat-exchanger 3, the position is put in tar strainer next door in the oil depot; Let about 160 ℃ oil fuel from steel basin come out the back earlier with about 80 ℃ the tar heat exchange that gets into one section pump, the tar after the heat exchange gets into former one section again and goes into the tower flow process; Said oil fuel pipeline 1 is connected with the tube side of said tar-usual heat-exchanger 3 through the pipe of ￠ 108; Said tar pipeline 2 is connected with the shell side of said tar-usual heat-exchanger 3 through the pipe of ￠ 133.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
