Collection system for flue gas from modified asphalt production

Abstract

The invention relates to flue gas treatment equipment, in particular relates to a collection system for flue gas from modified asphalt production, and solves the treatment problem of the flue gas fromthe modified asphalt production. The system includes a chamber for flue gas flow, a water tank for supplying water, and a fluid collection tank, the chamber is Z-shaped, the Z shape does not mean that the middle part of the chamber is an inclined straight line, on the contrary, in actual production and construction, the middle part of the chamber is parallel to the vertical direction in order tofacilitate flow of water and the flow of the flue gas; and one end of the bottom of the chamber has a flue gas inlet, one end of the top of the chamber has a flue gas discharge opening, that is, the flue gas flows from the bottom, when the flue gas flows upward along the middle of the chamber, the flue gas is liquefied by mist and flows down along the inner wall, and only when cleaning is needed,the remaining flue gas is discharged from the flue gas discharge opening. The system has a simple structure and high collection and treatment efficiency, saves costs, reduces the labor and material resource consumption, and has practicability and economy.

Description

technical field [0001] The invention relates to a flue gas treatment device, in particular to a modified bitumen flue gas collection system. Background technique [0002] Because bitumen contains mineral oil with high boiling point and a small amount of oxygen, sulfur and chlorine compounds, it may be oxidized and decomposed at high temperature to produce toxic gases such as hydrogen sulfide and sulfur dioxide. Asphalt fume and dust can cause poisoning through the respiratory tract and pollute the skin, causing symptoms such as dermatitis and blurred vision. The main pollutant to the environment during the production of modified asphalt is asphalt fume, which contains liquid or solid particles and harmful substances in vapor state. However, the flue gas treatment systems on the market have complex structures, high energy consumption, high processing costs, and low processing efficiency, which have greatly affected the active investment of various enterprises in asphalt flue...
