Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt smoke collecting and detecting devices, and in particular relates to a detachable rubber asphalt smoke collecting and detecting device. Background Art

[0002] According to statistics, by the end of 2020, my country will have the largest amount of waste tires in the world, but nearly 70% of waste tires have not been effectively recycled, and the recycling rate is only half of that of developed countries. A large amount of waste tires not only occupy land, but also bring unpredictable fire hazards, which have a serious impact on people and the environment. In order to effectively improve the current defects of ordinary rubber asphalt, combined with the current situation of the annual increase in the amount of waste tires produced, improving the compatibility of rubber and asphalt, increasing the rubber content, and reducing energy consumption and pollution in the production process will be the focus of road researchers.

[0003] The excellent performance of ordinary rubber asphalt has been proven in a large number of engineering practices. However, in recent years, with the introduction of government policies on environmental protection, energy conservation and emission reduction, the traditional production methods and use effects of rubber asphalt have also revealed obvious drawbacks and defects. It has gradually been unable to meet the needs of highway asphalt pavement construction under the current environmental protection situation, which has seriously restricted its further development. The main reason is that due to the obvious differences in the physical and chemical properties of asphalt and rubber, the compatibility between rubber and matrix asphalt is poor, resulting in ordinary rubber asphalt with high temperature viscosity, poor fluidity, poor dispersibility, incomplete swelling of rubber particles, difficulty in mixing the mixture, and difficulty in compacting the road surface. In addition, the rubber powder particles and asphalt are prone to stratification and segregation, resulting in poor high-temperature storage stability. Ordinary rubber asphalt must be processed and mixed on-site for use, and cannot be transported over long distances in the form of finished products. The above shortcomings have seriously limited the factory process and application scope of rubber asphalt. More importantly, in the current promotion process of ordinary rubber asphalt, it is found that a large amount of smoke and irritating odors (such as CO, NO) will be generated during both the production and construction stages. X , SO2, benzene, etc.), which not only pollutes the environment, but also brings serious harm to the health of construction workers. Ordinary rubber asphalt produces obvious smoke during production and construction, even to the extent of affecting vision, and emits a serious irritating odor. Therefore, the environmental pollution caused by the production and construction of ordinary rubber asphalt and its mixture cannot be ignored. In recent years, many asphalt processing companies have encountered such problems, which seriously affect the normal processing and use of rubber asphalt.

[0004] Based on environmental protection requirements, the flue gas of rubber asphalt must be collected and treated to avoid a large amount of flue gas from escaping during production and construction, which would cause serious pollution to the environment. In the prior art, the corona electrode wire and the precipitation electrode set in the treatment box are used to separate the tar contained in the asphalt flue gas when the rubber asphalt flue gas passes through the electrode space. The device has high efficiency in treating the tar in the rubber asphalt flue gas, but it has a negative impact on the smoke and irritating odors (such as CO, NO) in the rubber asphalt flue gas. X , SO2, benzene, etc.) are not treated, and the device is bulky and not suitable for laboratory use.

[0005] From the above analysis, the existing devices lack the function of separating and collecting smoke and irritating gases in asphalt smoke, and cannot well control the emission of smoke, resulting in a lack of accuracy in the test, and the inconvenience of putting in and taking out the rubber asphalt, which may damage the stirring device. In addition, there is currently no dedicated smoke collection device suitable for the Laoying 3012H automatic smoke (gas) tester. At the same time, the rubber asphalt smoke collection device is not set according to the smoke particles and gases. In the case of smoke particles accumulation, if they are not cleaned in time, it will cause damage to the detection instrument and subsequent gas collection.

[0006] Therefore, a detachable rubber asphalt smoke collection and detection device is needed. Utility Model Content
