Embodiment 1

[0046] This embodiment provides a heat exchange system 10 with a high-mounted tank, which aims to solve the existing problem of poor asphalt cooling effect in the high-mounted asphalt tank in the modified asphalt production system.

[0047] Please refer to figure 1 , figure 1 A schematic diagram of the high tank heat exchange system 10 is provided.

[0048] As shown in the figure, the high-set tank heat exchange system 10 includes an asphalt high-set tank 100, a heat conduction device 110, a heat exchanger 120, and a first pipeline 130. In the figure, the modified asphalt delivery pipeline 12 transports the asphalt high-set tank 100 Modified asphalt raw material. The direction of the arrow in the figure is the flow direction of the fluid.

[0049] Wherein, in this embodiment, there are two asphalt elevated tanks 100, and the number may be one, three or more in other implementation manners.

[0050] The heat conduction device 110 is arranged in the high asphalt tank 100, an...

Abstract

The invention discloses an overhead tank heat exchange system and a modified pitch production system and relates to the technical field of pitch production. The overhead tank heat exchange system comprises pitch overhead tanks, heat conduction devices arranged in the pitch overhead tanks, a heat exchanger, and a first pipeline through which the inlet of a first fluid channel communicates with the heat conduction device, wherein the heat conduction devices are configured to collect steam or / and steam condensate of a tar recovery section; the heat exchanger is provided with the first fluid channel and a second fluid channel and used for heat exchange between fluids in the first fluid channel and the second fluid channel; and the first fluid channel, as well as the second fluid channel, is provided with the inlet and an outlet. The problems that due to a poor heat exchange effect of pitch in a conventional pitch overhead tank, modified pitch products are poor in molding, the pitch discharge temperature is high, and heat of pitch cannot be effectively utilized are solved.

Description

technical field [0001] The invention relates to the technical field of asphalt production, in particular to a heat exchange system with high-set tanks and a modified asphalt production system. Background technique [0002] Modified asphalt is a black solid at room temperature, solidifies into a very brittle solid with a shell-like fracture at a certain temperature, and is in the glass phase; it does not have a certain melting point and melts within a certain melting point range, and has no thermal effect during solidification. The components of asphalt are extremely complex, most of which are aromatic hydrocarbons with more than three rings, as well as heterocyclic compounds containing elements such as oxygen, nitrogen and sulfur, and a small amount of high-molecular carbon substances. [0003] In the prior art, the asphalt cooling method in the asphalt high tank in the coal tar processing system adopts industrial circulating water for circulating cooling. Since the industri...
