Problems solved by technology

[0003] With more and more cars, the problem of exhaust emissions is becoming more and more serious. Automobile exhaust contains nitrogen oxides soluble in water. Nitrogen oxides are one of the main pollutants in the atmosphere. According to test data, when the average speed of the car is at When it is below 35km / h, the emission of nitrogen oxides is inversely proportional to the speed of the vehicle, that is, the lower the speed, the higher the emission of nitrogen oxides; in addition, with more and more cars, there are often traffic jams in the city If the car is running slowly or even at idling speed, it will emit a large amount of nitrogen oxides, which will have a bad impact on the environment.

Embodiment 1

[0019] Such as figure 1 As shown, a car idling exhaust purification isolation pile based on the resonance effect includes a base 1, the upper end of the base 1 is fixedly connected with a housing 2, and the inner top surface of the housing 2 is fixedly connected with a tuning fork 3. It should be noted that the tuning fork The resonant frequency of 3 is 10-20 Hz. When the car is running at low speed or at idle speed, the speed of the car is 700-1100r / min. According to the calculation formula of speed and frequency, when the car is at idle speed, the vibration generated by the engine When the frequency is 11.6-18.3 Hz, the tuning fork 3 will generate corresponding resonance. The tuning fork 3 is fixedly socketed with a plurality of magnet blocks 4 with the same magnetic pole direction. Both sides of the inner wall of the housing 2 are fixedly connected with induction coils 5. 5 is perpendicular to the direction of the magnetic force line of the magnet block 4, and the lower end...

Embodiment 2

[0022] Such as Figure 2-4 As shown, the difference between this embodiment and Embodiment 1 is that a connecting pipe 11 is fixedly connected between the drain pipe 9 and the atomizing nozzle 10, and a partition 12 is fixedly connected in the connecting pipe 11, and the partition 12 is provided with The opening is sealed and slidingly connected with a baffle plate 13, the upper end of the baffle plate 13 is fixedly connected with a vibrating plate 14, the upper end of the vibrating plate 14 is fixedly connected with the inner wall of the connecting pipe 11, and the vibrating plate 14 will bend to one side when it is vibrated .

[0023] In this embodiment, when a vehicle stays on one side of the isolation pile, the vibrating piece 14 on the side close to the vehicle will vibrate and bend. A gap appears between the inner walls of the connecting pipe 11, and the water flow enters the atomizing nozzle 10 from the gap. At the same time, the vibrating plate 14 on the side away fr...

Abstract

The invention belongs to the field of road facilities, in particular to an automobile idle tail gas purification isolation pile based on a resonance effect, which includes a base, the upper end of thebase is fixedly connected with a shell, A tune fork is fixedly connected with that top surface of the shell, the tuning fork is fixedly sleeved with a plurality of magnet blocks with the same magnetic pole direction, both sides of the inner side wall of the shell are fixedly connected with an induction coil, the induction coil is perpendicular to the magnetic force line direction of the magnet block, the lower end of the shell is fixedly connected with an inlet pipe communicated with an external water source, The water inlet pipe is fixedly connected with an electromagnetic valve, the electromagnetic valve is electrically connected with an induction coil, the output end of the water inlet pipe is fixedly connected with two drainage pipes respectively through a three-way valve, an end of the drainage pipe far away from the three-way valve is arranged through the shell, and the output end of the drainage pipe is fixedly connected with an atomization nozzle. The invention can spray wateraccording to the real-time situation of the vehicle, has good water-saving effect, and can reduce the emission of nitrogen oxides.

Description

technical field [0001] The invention belongs to the field of road facilities, and in particular relates to an isolation pile for purification of automobile idle exhaust gas based on a resonance effect. Background technique [0002] The isolation pile is a road traffic facility used to divide lanes and ensure driving safety. [0003] With more and more cars, the problem of exhaust emissions is becoming more and more serious. Automobile exhaust contains nitrogen oxides soluble in water. Nitrogen oxides are one of the main pollutants in the atmosphere. According to test data, when the average speed of the car is at When it is below 35km / h, the emission of nitrogen oxides is inversely proportional to the speed of the vehicle, that is, the lower the speed, the higher the emission of nitrogen oxides; in addition, with more and more cars, there are often traffic jams in the city If the car is running slowly or even at idling speed, it will emit a large amount of nitrogen oxides, w...
