Gas analyzer used for detecting pungent odor components of rubber asphalt and method for using gas analyzer to detect pungent odor components of rubber asphalt

Abstract

The invention discloses a gas analyzer used for detecting pungent odor components of rubber asphalt. The gas analyzer comprises a shell, a gas pump, a gas detection chamber and a gas adsorption box are arranged in the shell sequentially through a gas-guide pipe, a bell-shaped gas collector is arranged at the position where a gas pump inlet is communicated with the head of a gas intake pipe, a temperature sensor, a micro camera and distance meter are arranged on the bell-shaped gas collector, multiple gas sensors are arranged in the gas detection chamber, and the gas adsorption box is sequentially provided with a molecular sieve adsorption layer, a chemisorption cotton layer and an activated carbon layer along the flow of gas; a liquid crystal display is arranged on the front panel of the shell, and a fixing mechanism is arranged on the back of the shell. The gas analyzer is simple in structure, convenient in operation, rapid in detection and accurate in result; in the method, signal acquisition is performed by arranging the various gas sensors in the gas detection chamber, rapid analysis is performed through a single-chip microcomputer, the result can be directly displayed on the liquid crystal display visually, and injury to human body is effectively avoided.

Description

Technical field [0001] The invention relates to the technical field of gas analysis equipment, in particular to a gas analyzer for detecting irritating odor components of rubber asphalt, and a method for detecting irritating odor components of rubber asphalt by using the gas analyzer. Background technique [0002] Asphalt rubber is made by first processing the original quality of waste tires into rubber powder, and then combining them according to a certain coarse and fine gradation ratio. At the same time, adding a variety of high polymer modifiers, and fully mixing under high temperature conditions (above 180℃) ), a modified asphalt cementing material formed after full swelling reaction with base asphalt. The application of rubber asphalt can greatly reduce the harm and impact of waste tires on the natural environment. However, the pungent and odorous toxic gas produced during the production of rubber asphalt will affect the health of the surrounding staff. In order to reduce ...
