Energy-saving environmental-friendly type asphalt dissolving furnace having function of heat recovery

Abstract

The invention discloses an energy-saving environmental-friendly type asphalt dissolving furnace having a function of heat recovery. The energy-saving environmental-friendly type asphalt dissolving furnace comprises a dissolving pot, wherein an outer housing is arranged on the outer side surface of the dissolving pot; a reflux cabin is arranged at the upper end of the inner side surface of the outer housing; a combustion cabin is arranged between the lower end surface of the dissolving pot and the inner side surface of the outer housing; a heat conducting oil storing cabin is arranged between the inner side surface of the outer housing and the outer side surface of the dissolving pot; a liquid outlet pipe is arranged at the middle part of the lower end surface of the dissolving pot; a liquid outlet pipe valve is arranged on the liquid outlet pipe; the combustion cabin is connected with the reflux cabin through air guiding pipes; and an upper end cover is arranged right above the dissolving pot. The energy-saving environmental-friendly type asphalt dissolving furnace having the function of heat recovery disclosed by the invention is compact in structure, convenient to operate, and low in occupied space while in use; harmful gas generated in the dissolving process of asphalt can be effectively treated, and heat quantity of high-temperature flue gas can also be recovered; the atomizing nozzle is arranged, so that dust falling treatment of the flue gas is convenient; and air can be quickly blown in the combustion cabin through an air blower.

Description

technical field [0001] The invention relates to the technical field of asphalt dissolving equipment, in particular to a heat recovery, energy-saving and environment-friendly asphalt dissolving furnace. Background technique [0002] In recent years, with the rapid development of my country's industry and the full opening of the transportation industry, road construction has been carried out rapidly. my country's high-grade pavement is mainly based on asphalt pavement. Considering that the road surface maintains good road performance, hot mix asphalt is currently mainly Predominantly concrete. Therefore, our country is facing a serious air pollution problem, especially the organic matter represented by asphalt fume has attracted people's attention due to its high toxicity, complex composition and refractory nature, and has become a key and difficult point in environmental monitoring and treatment. When the asphalt is dissolved, the most harmful aromatic components in the aspha...

AI Technical Summary

Problems solved by technology

The existing asphalt dissolving furnace directly discharges the harmful gas produced by dissolving asphalt into the atmosphere when dissolving asphalt, and at the same time, the existing asphalt dissolving furnace cannot recover the heat energy in the high-temperature flue gas, resulting in a waste of energy
