Embodiment 1

[0034] refer to Figure 1-7 A high-temperature pyrolysis device for bio-asphalt materials, comprising a lower tray 3, the top outer wall of the lower tray 3 is provided with a furnace main body structure, the bottom four corners of the lower tray 3 are provided with brackets 4; the bottom side of the lower tray 3 is provided with The fan draws the heat accumulated in the lower furnace body from the lower side to the outer wall of the bucket, and simultaneously heats the temperature of the furnace body, and the waste heat recovery pipe 16 is located above the end of the fan. The main structure of the furnace body includes an upper furnace body 12, The lower furnace body 13, the outer shell 1 and the furnace cover 2, the upper furnace body 12 and the lower furnace body 13 are provided with a heat insulating plate 17, and the outer shell 1 is sleeved on the outer walls of the upper furnace body 12 and the lower furnace body 13, and the outer shell 1, the upper furnace body 12, an...

Embodiment 2

[0047] refer to Figure 8-9 : A kind of pyrolysis equipment for bio-asphalt materials, in this embodiment, with respect to embodiment 1, the main difference is that in this embodiment, it also includes a pear-shaped heating part 18-1, and the pear-shaped heating part 18-1 replaces the heating structure 18 positions, input the raw material to be cracked through the feed pipe 9, the raw material is distributed on the inner wall of a hemispherical cover, and also includes a spherical burning ball head 7-1 heated inside, wherein the burning ball head 7-1 The end is connected with a fuel feed pipe 19, which can evenly distribute the heat generated by the fuel combustion on the hemispherical cover to accelerate the heating of the raw material. At the same time, the concave heating structure reduces the heat dissipation of the heating surface and improves the heating efficiency. Further improve fuel utilization and thermal efficiency.

Abstract

The invention belongs to the technical field of biological asphalt, and particularly relates to high-temperature cracking equipment for a biological asphalt material. Aiming at the problems of low heat efficiency and high energy consumption, the high-temperature cracking equipment comprises a lower tray, a furnace body main body structure is arranged on the outer wall of the top of the lower tray, and brackets are arranged at four corners of the bottom end of the lower tray; and the furnace body structure comprises an upper furnace body, a lower furnace body, a shell and a furnace cover, a heat insulation plate is arranged between the upper furnace body and the lower furnace body, the shell is connected to the outer wall of the upper furnace body and the outer wall of the lower furnace body in a sleeving mode, and heat insulation layers are arranged between the shell and the upper furnace body and between the shell and the lower furnace body. The vertical structure is adopted, the funnel-shaped heavy material liquid separation hopper enables heavy materials to be layered through the temperature difference from bottom to top, the lower sphere is evenly heated through the burners on the four sides, heat conduction is fast, heating is even, the waste heat recovery structure is used for maintaining layering of the heavy materials, heavy material separation is clearer, and it is guaranteed that heat efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of bio-asphalt, in particular to high-temperature cracking equipment for bio-asphalt materials. Background technique [0002] With the rapid development of my country's economy and society, roads have entered the peak period of construction. About 90% of the roads repaired each year are asphalt pavements. At the same time, post-work such as road maintenance also consumes a large amount of petroleum asphalt. Biomass renewable energy such as crop straw, primary processing waste, and livestock excrement has many advantages such as wide distribution, convenient material acquisition, huge reserves, recycling, environmental protection, and low price, and has attracted extensive attention and research from relevant experts at home and abroad. [0003] The current rapid biomass pyrolysis technology has realized large-scale production in factories, and the products are mainly heavy and light bio-oils. Among them, th...
