Embodiment Construction
[0031] In conjunction with the accompanying drawings, a low-oxygen circulation road surface regenerative heater with air as a carrier includes a housing 1, a combustion chamber 2 is arranged inside the housing, and an air inlet 3 and a low-oxygen combustion chamber are arranged on the top of the combustion chamber. 4, the bottom end of the combustion chamber 2 is provided with an air outlet. An air outlet box 5 is arranged at the bottom of the housing 1 , and the air outlet communicates with the air outlet box 5 . A partition 6 is arranged inside the casing 1, and the partition 6 separates the casing into a return air collection area 7 and a return air passage 8, and a fan 9 is arranged on the top of the return air collection area 7, and the return air collection area 7 communicates with one end of the return air passage 8 through the fan 9, and the other end of the return air passage 8 communicates with the air inlet of the combustion chamber 2. The fan 9 sends the air into ...

The invention discloses a low-oxygen circulation road surface regeneration heater with air as a carrier, which comprises a casing, and a combustion chamber is arranged inside the casing. An air outlet is provided at the bottom of the chamber, and an air outlet box is provided at the bottom of the housing, the air outlet communicates with the air outlet box, and a partition is provided inside the housing, which separates the housing into a return air collection area and The return air passage is provided with a fan on the top of the return air collection area, and the return air collection area communicates with one end of the return air passage through the fan, and the other end of the return air passage communicates with the air inlet of the combustion chamber, and is arranged at intervals at the bottom of the air outlet box There are a plurality of slit nozzles, the total area of which is smaller than the area of the return air collection area. The working principle of hot air circulation heating adopted by the heating device of the present invention is that the high-temperature blower collects and reheats the waste gas that has completed the heating work, so as to achieve the effect of energy saving and emission reduction, and the effect is remarkable.
Description
technical field [0001] The invention relates to a device for in-situ thermal regeneration of asphalt pavement, in particular to a low-oxygen circulation pavement regeneration heater and heating method using air as a carrier. Background technique [0002] Hot-in-place regeneration of asphalt pavement is a pavement maintenance process that heats the old asphalt pavement with a hot-in-place regeneration unit, loosens it, adds regeneration agent and new asphalt mixture, then remixes it, paves it, and compacts it into shape. In the process of in-situ thermal regeneration of asphalt pavement, the heating plate is used to heat the ground first, and then the ground is raked by a rake, and the intermediate material cage is formed directly after the rake passes. The heating effect of the existing heating plate on the ground is not good, and the hot air after heating cannot be effectively used, which wastes energy and pollutes the environment. At the same time, the aging and oxidation ...
