Description

Technical Field

[0001] This utility model belongs to the field of purification device technology, and more specifically, it relates to a purification device for treating motor vehicle exhaust. Background Technology

[0002] Motor vehicle exhaust purification devices are core components installed in a vehicle's exhaust system to reduce the emission of harmful pollutants in exhaust gases. Through chemical reactions or physical filtration, they convert harmful gases produced by engine combustion into harmless substances, making them a key technological component for vehicles to meet environmental emission standards.

[0003] Under prolonged high-load operation or abnormal engine conditions, the excessively high temperature of the exhaust gas can easily lead to sintering and cracking of the catalyst carrier and thermal deformation and failure of the sealing material, resulting in reduced purification efficiency and leakage of harmful gases. Traditional purification devices mostly rely on passive heat dissipation structures, but their heat dissipation efficiency is limited by the thermal conductivity of the material and the air convection velocity, making it difficult to perform well in instantaneous high-temperature scenarios. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a vehicle exhaust gas treatment and purification device to solve the technical problem of insufficient cooling efficiency of traditional purification devices in instantaneous high-temperature scenarios.

[0005] The purpose and effectiveness of this utility model's motor vehicle exhaust gas treatment and purification device are achieved through the following specific technical means:

[0006] Motor vehicle exhaust gas treatment and purification device, including a purification mechanism:

[0007] A heat dissipation mechanism is installed around the purification mechanism;

[0008] The heat dissipation mechanism includes a sealed water jacket, and the purification mechanism is provided with a sealed water jacket for storing heat-conducting fluid on its periphery. A heat dissipation pipe for transporting coolant is installed inside the sealed water jacket.

[0009] The heat dissipation pipe has a spiral structure and is wound around the periphery of the purification mechanism. Both the inlet and outlet ends of the heat dissipation pipe are equipped with one-way valves. One end of the purification mechanism is equipped with an oxygen sensor and a temperature sensor. A heat dissipation pipe is welded to one end of the purification mechanism. Multiple sets of heat dissipation fins are arranged around the periphery of the heat dissipation pipe. A cooling fan is installed at one end of the heat dissipation pipe.

[0010] The above technical solution further includes: a control module is provided on the top of the purification mechanism;

[0011] The oxygen sensor, temperature sensor, and cooling fan are all electrically connected to the control module; one end of each of the two sets of one-way valves is connected to the vehicle's cooling system.

[0012] The above technical solution further includes: a fixing component is provided at the end of the purification mechanism;

[0013] The fixing assembly includes two sets of fixing tubes, one set of which is connected to one end of the purification mechanism, and the other set of fixing tubes is connected to one end of the heat dissipation tube.

[0014] The above technical solution further includes: multiple sets of mounting platforms are provided around the periphery of both sets of fixed pipes, and a first mounting seat is installed on each mounting platform.

[0015] The above technical solution further includes: each of the first mounting bases is bolted with a fixing rod, and a second mounting base is installed at one end of each fixing rod.

[0016] The above technical solution further includes: a fixing frame is installed at the bottom of each of the multiple sets of second mounting seats, and a fixing block is installed at the bottom of each fixing frame.

[0017] The above technical solution further includes: a fixing cover is provided at one end of each of the two sets of fixing tubes;

[0018] A fixing ring is installed at one end of the purification mechanism, and a fixing bolt is provided at the top of the fixing ring.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the design of the heat dissipation mechanism, when using this device, the spiral heat dissipation pipe surrounds the purification mechanism. Combined with the heat exchange capacity of the heat-conducting fluid in the sealed water jacket, the exhaust temperature can be stably controlled, preventing damage to the purification mechanism under high-temperature conditions. When the vehicle is under rapid acceleration or high load, the temperature sensor detects that the exhaust gas temperature is high. The control module controls the cooling fan to start, which reduces the temperature of the gas in the heat dissipation pipe through air cooling. This reduces the thermal expansion difference within the purification mechanism, thereby preventing cracking of the purification mechanism due to thermal expansion difference. This solves the problem of insufficient cooling efficiency of the purification device in instantaneous high-temperature scenarios.

[0021] 2. By setting up the fixing components, when the device is installed, the spacing between the fixing brackets can be adjusted by adjusting the tightness of the bolts between multiple fixing brackets on the same end to adapt to different exhaust pipe models. The fixing blocks are made of elastic material, and the device contacts the exhaust pipe through the fixing blocks to buffer the high-frequency vibration during exhaust gas emission, making the device more practical.
