Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tail gas particle treatment, and more particularly to a vehicle tail gas particle treatment device. BACKGROUND

[0002] Therefore, in the current rapid development of the automobile industry, vehicle tail gas emission has become one of the important sources of air pollution. The particulate matter (such as PM2.5, soot particles, etc.) in the tail gas not only reduces air quality, but also causes serious harm to the respiratory system and cardiovascular system of the human body, and aggravates environmental problems such as haze and photochemical smog. In response to this challenge, countries have continuously tightened vehicle tail gas emission standards, and higher requirements have been put forward for the treatment efficiency of particulate matter in tail gas. At present, although a three-way catalyst is generally equipped in the vehicle tail gas treatment system to convert gaseous pollutants such as carbon monoxide and nitrogen oxides, the filtering capacity of the three-way catalyst for particulate matter is limited, and it is difficult to effectively intercept the solid particles in the tail gas. Therefore, a special particulate matter treatment device needs to be additionally matched to meet the increasingly stringent emission regulations and reduce the impact of particulate matter on the environment and the human body. The traditional vehicle tail gas particulate matter treatment device mostly adopts a single filter bin structure and relies on a filter element (such as a filter barrel or a filter core) to intercept particulate matter. However, such a device has obvious defects in long-term use: on the one hand, the filter element is prone to clogging due to the accumulation of particulate matter, which increases the resistance of the tail gas flow, reduces the engine power performance, and causes the tail gas emission to exceed the standard due to the decrease in the filtering efficiency; on the other hand, the traditional device lacks an effective clogging monitoring and self-adaptive adjustment mechanism, and cannot sense the working state of the filter element in real time, so it needs to be manually disassembled, cleaned or replaced regularly, which is high in maintenance cost and cumbersome in operation. At the same time, although some devices are equipped with a simple anti-clogging structure, they cannot dynamically adjust the working mode according to the concentration of tail gas particulate matter and the engine operating conditions, and when the engine is running at high load (such as high-speed driving and sudden acceleration), the amount of particulate matter produced increases suddenly, which causes insufficient treatment capacity and cannot continuously and stably meet the tail gas treatment demand. Therefore, the existence of a vehicle tail gas particulate matter treatment device is very important. SUMMARY

[0003] The present application aims to provide a vehicle tail gas particulate matter treatment device to solve the problems raised in the background.

[0004] A device for treating particulate matter from automobile exhaust, comprising a three-way catalytic converter, wherein a first connecting flange is fixedly provided on one side of the three-way catalytic converter, and a first three-way valve is fixedly connected to the first connecting flange, and the other side of the three-way catalytic converter is fixedly connected to the exhaust port of the automobile engine, an intake pipe is fixedly provided on one side of the first three-way valve, and one side of the intake pipe is fixedly connected to the first connecting flange, the output ends on both sides of the first three-way valve are fixedly connected to the first three-way pipes, the bottom openings of the two first three-way pipes are fixedly connected to the particle treatment bin, the side openings of the two particle treatment bins are sealed, the particle inlet pipes are fixedly provided on one side of the two particle treatment bins, and are fixedly connected to the two first three-way pipes respectively through the particle inlet pipes, and the two A filter barrel is fixedly installed inside the particle processing bin, and a plurality of filter holes are opened horizontally through the inside of the filter barrel. A crushing and anti-blocking mechanism is provided on the side of the filter barrel close to the first three-way valve inside the two particle processing bins. A particle outlet pipe is fixedly installed on the other side of the two particle processing bins, and both are fixedly connected to a second three-way pipe through the particle outlet pipe. A second three-way valve is fixedly connected between the top openings of the two second three-way pipes, and the openings on the other side of the two second three-way valves are sealed. An exhaust pipe is fixedly installed at one side outlet of the second three-way valve, a second connecting flange is fixedly installed on one side of the exhaust pipe, and one side of the second connecting flange is fixedly connected to the exhaust outlet of the automobile. An intelligent detection center is fixedly installed on one side of the inside of the three-way catalytic converter.

[0005] Preferably, the crushing and anti-blocking mechanism includes a fixed frame fixedly arranged inside the particle processing bin and located on one side of the particle inlet pipe, a sliding shaft is rotatably arranged inside the fixed frame, a stirring rod is rotatably arranged at the bottom of the sliding shaft, the bottom of the stirring rod is tightly fitted with the filter barrel, the stirring rod is composed of a plurality of fan-shaped rods, a shovel surface is provided at the bottom, and a micro-drive motor is provided inside, the stirring rod is rotated by the exhaust gas discharged from the particle inlet pipe, a connecting shaft is fixedly arranged on the top of the stirring rod, the connecting shaft is rotatably arranged inside the sliding shaft, and there is a certain sliding space above and below, a shock-absorbing spring is fixedly arranged on the top of the connecting shaft, the shock-absorbing spring is rotatably arranged inside the sliding shaft, and the top is tightly fitted with the inside of the sliding shaft.

[0006] Preferably, the intelligent detection center is internally integrated with a particulate matter concentration sensor and a pressure sensor. The particulate matter concentration sensor is used to monitor the initial concentration of particulate matter in the exhaust gas output by the three-way catalytic converter in real time, and the pressure sensor is used to monitor the air pressure values ​​inside the two particulate treatment bins. The intelligent detection center can automatically determine the degree of blockage of the filter barrel based on the initial concentration of particulate matter and the difference in air pressure inside the particulate treatment bin. When it is detected that the air pressure difference of one of the particulate treatment bins reaches a preset threshold, the electromagnetic drive components built into the first three-way valve and the second three-way valve are controlled to switch the passage, thereby ensuring that the exhaust gas is always processed through the particulate treatment bin with good filtering effect.

[0007] Preferably, the intelligent detection center establishes a linkage control with the crushing and anti-blocking mechanism, and monitors the rotation rate of the stirring rod in real time through the built-in speed sensor. When it is detected that the rotation speed of the stirring rod is lower than the preset value, it is determined that stubborn particles may be accumulated on the surface of the filter barrel. The intelligent detection center will start the micro-drive motor that is matched with the crushing and anti-blocking mechanism, and increase the fitting pressure between the stirring rod and the filter barrel by adjusting the sliding range of the connecting shaft in the sliding shaft.

[0008] Preferably, the intelligent detection center is equipped with a temperature monitoring module and a heating control module. The temperature monitoring module is used to collect temperature data inside the particle processing bin and the filter barrel in real time. When it is detected that the temperature is lower than the suitable temperature range for exhaust gas treatment, the heating control module will drive the heating wire assembly outside the particle processing bin to work, so that the filter barrel is maintained in a temperature range that is conducive to particulate matter filtration and decomposition.

[0009] Preferably, the intelligent detection center has data storage and analysis functions, built-in storage chip and CAN bus driver module, which can continuously record data such as the working parameters of the three-way catalytic converter, the switching frequency of the two particle treatment chambers, the number of cleaning times of the filter barrel, and the changes in pollutant concentration before and after exhaust gas treatment. After analyzing these data through the built-in algorithm, the equipment operation status report and maintenance recommendations are transmitted to the vehicle display screen with the help of the CAN bus driver module.

[0010] Preferably, the intelligent detection center is integrated with a fault diagnosis module, which can monitor the operating status of key components such as the first three-way valve, the second three-way valve, the particle processing bin and the crushing and anti-blocking mechanism in real time. When abnormal operation of a component is detected, the valve switching fails, and the stirring rod is stuck, the alarm drive circuit will be triggered immediately, driving the vehicle-mounted buzzer and warning light to work, and the fault location and type will be displayed on the vehicle-mounted display screen.

[0011] Preferably, the intelligent detection center establishes a communication connection with the automobile engine control system through a CAN bus drive module, and can obtain real-time operating information such as the engine speed, load, and fuel injection volume. According to changes in the engine operating conditions, the electromagnetic drive components of the first three-way valve and the second three-way valve are controlled in advance to adjust the switching strategy, and at the same time, the airflow regulating valve of the particle treatment bin is driven to change the working mode. When the engine is running at high load, it switches to the particle treatment bin with a larger filtration area in advance.

[0012] Preferably, the intelligent detection center is provided with an adaptive learning module, which continuously optimizes the filter barrel blockage judgment threshold, the working parameters of the anti-blocking mechanism and the switching logic of the three-way valve by recording various parameters and effects of exhaust gas treatment under different working conditions for a long time. The optimized parameters are transmitted to each execution component, micro drive motor and electromagnetic drive component through the drive control unit, so that the operating state of the equipment gradually adapts to the usage habits and driving environment of a specific vehicle.

[0013] Preferably, the intelligent detection center is equipped with an exhaust emission compliance monitoring function, a built-in emission comparison chip and a pneumatic drive component, which can compare the pollutant concentration data of the treated exhaust gas with the regional emission standards in real time. When it is detected that the emission data exceeds the standard, the cause of the exceedance is immediately analyzed, and the pneumatic drive component is driven to forcibly switch the particle processing bin, and at the same time control the micro-drive motor of the crushing and anti-blocking mechanism to enhance the cleaning force, and record the exceedance event for subsequent inquiry.

[0014] Compared with the prior art, the advantages of the present invention are: Through innovative structural design and intelligent control system, the exhaust particulate matter treatment efficiency, equipment operation stability and maintenance convenience have been comprehensively improved. It can not only efficiently intercept and treat solid particles in the exhaust gas to meet the strict automobile exhaust emission standards, but also effectively solve the problems of easy clogging, unstable treatment capacity and high maintenance costs of traditional devices through dynamic monitoring and adaptive adjustment, providing a more efficient, reliable and intelligent solution for automobile exhaust treatment.

[0015] In terms of structural design, the device utilizes a switching structure combining two particle treatment chambers and dual three-way valves. This, coupled with real-time monitoring and control from an intelligent detection center, allows for dynamic switching between the two treatment chambers. If the filter barrel in one of the treatment chambers becomes clogged due to particulate accumulation (when the pressure differential reaches a preset threshold), the intelligent detection center rapidly switches the first and second three-way valves, ensuring that exhaust gas consistently flows through the treatment chamber with optimal filtration. This avoids the increased exhaust flow resistance, reduced engine power, and excessive emissions associated with the blockage of a traditional single filter chamber, significantly improving the continuity and stability of the device's operation. In the aspect of intelligent regulation and anti-blocking ability, the device constructs a multi-dimensional anti-blocking guarantee system through the linkage control of the intelligent detection center and the stirring anti-blocking mechanism. On the one hand, the intelligent detection center monitors the stirring rod speed through the speed sensor, and when the speed is lower than the preset value (judging that stubborn particles are accumulated), the micro drive motor can be started to adjust the sliding range of the connecting shaft, increase the fitting pressure of the stirring rod and the filter barrel, and strengthen the particle cleaning effect. On the other hand, the cooperation of the temperature monitoring module and the heating control module can make the filter barrel always maintain in the temperature range conducive to the filtration and decomposition of particles, further improving the filtration efficiency. This kind of closed-loop control of "monitoring - judging - adjusting" greatly reduces the probability of filter barrel blockage, prolongs the service life of the filter element, and reduces the frequency of manual cleaning. In the aspect of maintenance cost and adaptability optimization, the data storage and analysis function of the intelligent detection center and the adaptive learning module provide strong support for low-cost maintenance and personalized adaptation of the device. The data storage function can record key data such as three-way catalyst working parameters, treatment bin switching frequency, filter barrel cleaning frequency, etc., and transmit them to the vehicle display screen through the CAN bus to provide accurate maintenance suggestions for users and avoid blind maintenance; the adaptive learning module can continuously optimize the blockage judgment threshold, stirring anti-blocking mechanism working parameters and three-way valve switching logic by long-term recording of treatment parameters and effects under different working conditions, so that the device gradually adapts to the use habits and driving environment of specific vehicles, further improving the operating efficiency and stability.

[0016] In the aspect of emission compliance guarantee, the intelligent detection center of the device integrates the tail gas emission compliance monitoring function, which can compare the pollutant concentration of the treated tail gas with the national / regional emission standards in real time. When the emission is detected to be over standard, the cause can be analyzed immediately and forced measures can be taken - forced switching of particle treatment bin, and enhanced cleaning of the stirring anti-blocking mechanism to ensure that the tail gas quickly recovers to meet the emission standards, while recording the over-standard events for subsequent inquiry. In addition, the intelligent detection center is communicatively connected with the automobile engine control system, which can adjust the treatment bin switching strategy and air flow valve mode in advance according to the engine speed, load and other working conditions, and switch to the treatment bin with larger filter area in advance when the engine is running at high load, to guarantee the tail gas treatment capacity and emission compliance from the source.

[0020] Specifically, the anti-blocking mechanism includes a fixed frame 33 fixedly arranged in the particle treatment bin 3 and located on one side of the particle inlet pipe 30, a sliding shaft 34 rotatably arranged in the fixed frame 33, a stirring rod 35 rotatably arranged at the bottom of the sliding shaft 34, the stirring rod 35 being tightly attached to the filter barrel 32 at the bottom, the stirring rod 35 being composed of a plurality of fan-shaped rods, a shovel surface being arranged at the bottom, and a micro drive motor being arranged inside, the stirring rod 35 being driven to rotate by the exhaust gas discharged through the particle inlet pipe 30, a connecting shaft 36 being fixedly arranged at the top of the stirring rod 35, the connecting shaft 36 being rotatably arranged in the sliding shaft 34 and having a certain sliding space above and below, a shock-absorbing spring 37 being fixedly arranged at the top of the connecting shaft 36, and the shock-absorbing spring 37 being rotatably arranged in the sliding shaft 34 and being tightly attached to the inside of the sliding shaft 34 at the top; When the exhaust gas enters the particle treatment bin 3 from the particle inlet pipe 30, the stirring rod 35 at the bottom of the sliding shaft 34 in the fixed frame 33 is driven to rotate, the shovel surface at the bottom of the stirring rod 35 is attached to the filter barrel 32, and the particles accumulated on the surface are scraped off; the connecting shaft 36 can slide up and down in the sliding shaft 34, and the top shock-absorbing spring 37 buffers the impact force when the stirring rod 35 rotates, so as to avoid damage to the filter barrel 32; the built-in micro drive motor in the stirring rod 35 can assist in adjusting the rotating state, the stirring rod 35 is driven to rotate by the exhaust gas, active anti-blocking is realized, and the probability of clogging of the filter barrel 32 is reduced; the design of the shock-absorbing spring 37 and the slidable connecting shaft 36 can not only ensure the attachment of the stirring rod 35 and the filter barrel 32, but also avoid damage to the filter barrel 32 caused by rigid contact, thereby prolonging the service life of the filter element.

[0021] Specifically, the intelligent detection center integrates a particle concentration sensor and a pressure sensor. The particle concentration sensor is used to monitor the initial concentration of particulate matter in the exhaust gas output by the three-way catalytic converter 1 in real time, and the pressure sensor is used to monitor the air pressure inside the two particulate treatment chambers 3. The intelligent detection center can automatically determine the degree of blockage of the filter barrel 32 based on the difference between the initial particle concentration and the air pressure inside the particulate treatment chamber 3. When it is detected that the air pressure difference in one of the particulate treatment chambers 3 reaches a preset threshold, the intelligent detection center controls the electromagnetic drive components built into the first three-way valve 2 and the second three-way valve 4 to switch the path, ensuring that the exhaust gas always passes through the particulate treatment chamber 3 with good filtering effect for treatment; The particle concentration sensor of the intelligent detection center monitors the initial concentration of particulate matter in the exhaust gas output by the three-way catalytic converter 1 in real time, and the pressure sensor monitors the internal air pressure values ​​of the two particle treatment chambers 3; by comparing the initial concentration of particulate matter with the air pressure difference between the two chambers, the blockage degree of the filter barrel 32 is judged; when the air pressure difference of a particle treatment chamber 3 reaches the preset threshold value, the intelligent detection center controls the electromagnetic drive parts of the first three-way valve 2 and the second three-way valve 4 to switch the path, so that the exhaust gas only passes through the particle treatment chamber 3 with good filtering effect, realizing real-time monitoring and automatic judgment of the blockage status of the filter barrel 32, and quickly switching the path through the three-way valve to ensure that the exhaust gas is always discharged after effective filtration, avoiding the problem of excessive emissions and reduced engine power due to the blockage of a single chamber, and improving the continuity of equipment operation.

[0022] Specifically, the intelligent detection center establishes a linkage control with the crushing and anti-blocking mechanism, and monitors the rotation rate of the stirring rod 35 in real time through the built-in speed sensor. When it detects that the rotation speed of the stirring rod 35 is lower than the preset value, it is determined that there may be stubborn particles accumulated on the surface of the filter barrel 32. The intelligent detection center will start the micro drive motor of the crushing and anti-blocking mechanism and increase the contact pressure between the stirring rod 35 and the filter barrel 32 by adjusting the sliding range of the connecting shaft 36 within the sliding shaft 34. The intelligent detection center monitors the rotation rate of the stirring rod 35 through the speed sensor. When the speed is lower than the preset value and it is determined that stubborn particles have accumulated on the surface of the filter barrel 32, the intelligent detection center starts the micro-drive motor of the crushing and anti-blocking mechanism; the micro-drive motor adjusts the sliding range of the connecting shaft 36 in the sliding shaft 34, increases the fitting pressure between the stirring rod 35 and the filter barrel 32, and enhances the effect of the shovel surface in cleaning stubborn particles. It establishes a linkage mechanism of "speed monitoring-stubborn blockage judgment-pressure regulation", solves the problem of stubborn particle accumulation in a targeted manner, avoids the continuous decline in filtration efficiency due to particles that cannot be cleaned by conventional stirring, and further improves the reliability of anti-blocking.

[0023] Specifically, the intelligent detection center is equipped with a temperature monitoring module and a heating control module. The temperature monitoring module is used to collect real-time temperature data inside the particle processing chamber 3 and the filter barrel 32. When the temperature is detected to be lower than the suitable temperature range for exhaust gas treatment, the heating control module will drive the heating wire assembly outside the particle processing chamber 3 to operate, so that the filter barrel 32 is maintained in a temperature range that is conducive to the filtration and decomposition of particulate matter. The temperature monitoring module of the intelligent detection center collects the temperature data of the inside of the particle processing chamber 3 and the filter barrel 32 in real time; when the temperature is lower than the suitable range for exhaust gas treatment, the heating control module drives the heating wire assembly outside the particle processing chamber 3 to work, and through heat transfer, the temperature of the filter barrel 32 is maintained in a range that is conducive to the filtration and decomposition of particulate matter, eliminating the influence of temperature on the particulate matter treatment effect, ensuring that the filter barrel 32 can maintain high-efficiency filtration and decomposition capabilities under different working conditions such as cold start and low temperature environment, and avoiding fluctuations in treatment efficiency caused by too low temperature.

[0024] Specifically, the intelligent detection center has data storage and analysis capabilities. Its built-in storage chip and CAN bus driver module continuously record data such as the operating parameters of the three-way catalytic converter 1, the switching frequency of the two particulate treatment chambers 3, the number of cleanings of the filter barrel 32, and changes in pollutant concentrations before and after exhaust treatment. After analyzing this data using a built-in algorithm, the CAN bus driver module transmits equipment operating status reports and maintenance recommendations to the vehicle's display screen. The storage chip of the intelligent detection center continuously records data such as the working parameters of the three-way catalytic converter 1, the switching frequency of the particle treatment chamber 3, the number of cleaning times of the filter barrel 32, and the changes in the exhaust pollutant concentration.

[0026] Specifically, the intelligent detection center establishes a communication connection with the vehicle engine control system via a CAN bus driver module, enabling real-time acquisition of engine operating condition information such as engine speed, load, and fuel injection volume. Based on changes in engine operating conditions, the center proactively controls the electromagnetic actuators of the first three-way valve 2 and the second three-way valve 4 to adjust the switching strategy. Simultaneously, the center drives the airflow control valve of the particle processing chamber 3 to change its operating mode, switching to the particle processing chamber 3 with a larger filtration area in advance when the engine is operating at high load. The intelligent detection center communicates with the vehicle engine control system through the CAN bus driver module to obtain real-time operating information such as engine speed, load, and fuel injection volume; according to changes in operating conditions, the electromagnetic drive components of the first three-way valve 2 and the second three-way valve 4 are controlled in advance to adjust the switching strategy, and the airflow regulating valve of the particle treatment chamber 3 is driven to change the working mode; for example, when the engine is under high load, it switches to the particle treatment chamber 3 with a larger filtration area in advance, realizing the coordinated adaptation of the equipment and the engine operating conditions, avoiding insufficient processing capacity due to sudden changes in operating conditions such as rapid acceleration and high-speed driving, ensuring that the exhaust gas treatment effect always matches the amount of particulate matter generated, and improving the adaptability and stability of the equipment.

[0027] Specifically, the intelligent detection center is equipped with an adaptive learning module. By long-term recording of various exhaust gas treatment parameters and effects under different operating conditions, it continuously optimizes the filter barrel 32 blockage judgment threshold, the operating parameters of the crushing anti-blocking mechanism, and the switching logic of the three-way valve. The optimized parameters are transmitted to each actuator, micro drive motor, and electromagnetic drive component through the drive control unit, so that the operating status of the equipment gradually adapts to the usage habits and driving environment of a specific vehicle.
