Problems solved by technology

[0004] However, there is currently no asphalt mixture flue gas equipment with comprehensive treatment functions on the market
The traditional flue gas treatment device mainly has the following problems: First, the traditional flue gas detection mainly uses a manual hand-held flue gas sampling device to collect flue gas samples, which is labor intensive and cannot detect flue gas emissions during the mixing process in real time
Secondly, during the operation of the flue gas collection device in the prior art, the problem of filter screen blockage often occurs, which affects the flue gas collection efficiency
In addition, the current asphalt fume treatment devices mostly focus on asphalt cement, and there is a lack of asphalt mixture fume treatment devices. In the road field, road construction materials mostly exist in the form of asphalt mixture.

Abstract

The invention discloses an asphalt mixture flue gas detection / collection integrated device, relates to a flue gas detection / collection device and a test method, and aims to solve the problems that the traditional flue gas detection labor amount is relatively large and flue gas emission in the asphalt mixture production process cannot be detected in real time. The system comprises a flue gas generation unit, a particle filtering unit, a flue gas treatment unit, a first external gas conveying pipeline and a second external gas conveying pipeline, the flue gas generation unit is connected with the particle filtering unit through the first external gas conveying pipeline, and the particle filtering unit is connected with the flue gas treatment unit through the second external gas conveying pipeline. The device disclosed by the invention not only can realize closed collection of asphalt mixture flue gas, but also can realize real-time detection of the flue gas concentration in a mixture mixing process; the flue gas detection method can be used for detecting the full-life flue gas concentration of the asphalt mixture in different stages from production to paving, and a reliable basis is provided for supplementing flue gas data of the full-life cycle of the asphalt mixture.

Description

technical field [0001] The invention relates to a smoke detection / collection device and a test method, an asphalt mixture smoke detection / collection integrated device and a test method, and the invention is applied in the technical field of asphalt mixture smoke treatment. Background technique [0002] In recent years, waste rubber powder modified asphalt technology has been gradually developed and widely used, which not only significantly improves the road performance of asphalt, but also provides an effective way for the recycling and reuse of a large number of accumulated waste tires, alleviating the It eliminates the environmental problems caused by tire stacking or incineration, and is in line with the sustainable development strategy. [0003] However, high-temperature operating conditions lead to high smoke emissions during the production, mixing and construction of rubber asphalt. When the pavement temperature reaches 180°C, the concentration of asphalt smoke can rea...
