Problems solved by technology

After the SCR system is used for a long time, the spray accessories in the SCR system will be blocked due to the crystallization of urea for vehicles or the carbon deposits generated after the combustion of water-insoluble substances inside it, but due to the crystallization or deposits of urea for vehicles The color of the spray is relatively dull. When the spray accessories in the SCR system are clogged, they cannot be effectively detected, so that the clogs cannot be dealt with in time, and the damage to the SCR system will be aggravated.

Embodiment 1

[0037] see Figure 1-3 , a new type of automobile exhaust purification treatment liquid, its composition is: high-purity urea solution, ethanol, propylene glycol, magenta solution and deionized water, according to the weight content is: high-purity urea solution 30-35 parts, ethanol 6- 10 parts, 4-8 parts of propylene glycol, 1-5 parts of magenta and 15-20 parts of deionized water. By adding magenta solution to color the automobile exhaust purification treatment liquid, the urea can be effectively colored and the alertness of the urea color can be improved. When the spray accessories in the SCR system are clogged, the car owner or maintenance personnel can Fast and effective detection of blockage points can timely maintain the SCR system and reduce the damage of the SCR system.

[0038] see figure 1 , the mass fraction of urea in the high-purity urea solution is 50-60%.

[0039] The urea is colored red by magenta so that urea crystals or other blockages can be seen effectiv...

Embodiment 2

[0041] see Figure 1-3, where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to figure 1 , according to the weight parts: 32-35 parts of high-purity urea solution, 10-12 parts of ethanol, 6-10 parts of propylene glycol, 2-6 parts of magenta and 20-35 parts of deionized water. The ethanol can effectively reduce the freezing point of the vehicle exhaust gas purification treatment fluid, so that it can be used normally in cold weather, reduce the burden on the SCR system, and improve the applicability of the vehicle exhaust gas purification treatment fluid.

Embodiment 3

[0043] see Figure 1-3 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to figure 1 , according to the weight parts: 30-35 parts of high-purity urea solution, 4-10 parts of ethanol, 6-8 parts of propylene glycol, 2-4 parts of magenta and 20-30 parts of deionized water. Propylene glycol lowers the freezing point of the vehicle exhaust gas purification treatment fluid while protecting the components in the SCR system, effectively lubricating and protecting the inner wall of the spray accessory, and prolonging its service life.

Abstract

The invention discloses novel automobile exhaust purification treating fluid and a preparation method thereof, and belongs to the field of automobiles. According to the novel automobile exhaust purification treating fluid and the preparation method, the novel automobile exhaust purification treating fluid comprises the following components including a high-purity urea solution, ethanol, propanediol, a magenta solution and deionized water; the magenta solution can be added to perform coloring treatment on the automobile exhaust purification treating fluid, so that urea can be effectively developed, the warning degree of the urea color is improved, when a spraying accessory in an SCR system is blocked, an automobile owner or maintenance personnel can quickly and effectively perceive a blocked point, the SCR system can be timely maintained, and the damage degree of the SCR system is reduced; and all solutions are pretreated in a classified mixing manner, so that the urea, magenta and propanediol solution efficiency and dissolving quality are effectively improved, the preparation time is effectively shortened, the urea can be effectively colored through the magenta, and the coloring degree is improved.

Description

technical field [0001] The invention relates to the field of automobiles, and more specifically relates to a novel automobile tail gas purification treatment liquid and a preparation method thereof. Background technique [0002] As one of the main sources of air pollution, automobile exhaust contains a large number of harmful substances, including carbon monoxide, nitrogen oxides, hydrocarbons and solid suspended particles. PM2.5, which has become the focus of social attention, belongs to the category of solid suspended particles. In addition to being one of the main sources of PM2.5 in large cities, vehicle exhaust is also one of the chief culprits of air pollution in many cities, and photochemical smog is one of its main effects. Exhaust gas not only directly endangers human health, but also has a profound impact on the environment in which human beings live. The sulfur dioxide in the tail gas has a strong pungent smell, and when it reaches a certain concentration, it wi...
