Summary of achievements:
According to statistics, among the total emissions of various air pollutants, emissions from vehicles in mobile pollution sources are the most serious. Among them, granular pollutants discharged from diesel vehicles are one of the major sources of pollution affecting air quality. To control the county's diesel engine-based mobile pollution sources and reduce their emissions to reduce air pollution on the health hazards caused to the citizens, Hualien County Environmental Protection Agency in the implementation of this year, "Hualien County garbage truck filter device demonstration run Plan ", the implementation of soot filter installation of real car operation, in order to enhance the quality of the county's air.
Based on the analysis of the operation data of the soot filter installed in the garbage truck and the implementation results and practical experience of the project, we will make suggestions as to how to make the smoke emission control of diesel vehicles in our county more effective. A reference to the regulatory strategy.
The current program's results are summarized as follows:
(A) cleaning team diesel vehicles survey
According to the statistical data of clean vehicles in Hualien City Office provided by the Environmental Protection Agency in 104 years, a total of 25 vehicles including the compression vehicles and resource recovery vehicles were screened for the third phase of the project.
(B) is the right combination of pre-installation and maintenance
20 vehicles were selected according to the test records before the vehicles and listed as priority vehicles. After the current investigation and implementation of the pre-installation vehicle maintenance and repair work to ensure that the filter body after installation of the car body without any damage.
(C) inspection and installation operations
1. Install soot filter CGT240-MC models a total of 19 groups; CGT190-SC model 1 group.
2. Check the vehicle condition after the selected vehicle is installed.
(D) education and training for handling
The vehicle maintenance staff of the vehicle for cleaning vehicle filters has completed 3 training sessions.
(E) questionnaire survey and advocacy
1. To handle 7 habits questionnaires for drivers, a total of 141 valid questionnaires were retrieved.
2. This project demonstrated the slogan "I smoke cigarettes. You health" on the side of the vehicle equipped with a soot filter so as to let the public directly experience the actual improvement of air pollution after the installation of pollution control equipment on the garbage truck
(Vi) the results of the demonstration filter operation of this stage
The project will demonstrate the operation of 20 vehicles with soot filters installed so as to have a good understanding of the operation of the existing soot filter installed in the refuse collection vehicles for reference of the department for the subsequent promotion of soot filters for diesel vehicles.
Since February 1, 2005, the operation of installation and inspection of filter soot has been completed and formal demonstration operation has been carried out. As of the reporting date (2017.10.31), the operation period was 21 months. The demonstration operation of 20 sets of soot filter vehicles The detailed operating conditions are described separately in Section 4.5.1; the overall demonstration operation is described below.
Until 2017.10.31, the most common problems in demonstration operation were abnormal regeneration caused by various reasons. Most of the situations were eliminated after the engineers in the project were repaired. However, some of the problems appeared frequently and the plans were all reflected Filter cigarette factory manufacturing, negotiate to improve the program. The ignition needle (stick) due to garbage truck driving vibration caused by loose or angle change fixed point can not be caused by the regeneration of the current factory has changed the fixed way, the follow-up will continue to observe, if there are still problems, consider the replacement of another brand Suppliers; parts of the nozzle after a period of time due to congestion will not be able to normal oil regeneration, the United States and Denmark have been replaced during the import of the brand, but still can not be completely resolved, the original is trying to deal with, and consortia Corporate Vehicle Research and Testing Center, with a view to solve this problem as soon as possible, currently only continuous monitoring of the situation, such as the failure to replace the new product; temperature bar (line) due to car wash water and moisture caused by conduction failure, the current installation After the waterproof cover has been improved, the follow-up will continue to track; and loose equipment vehicles (such as tank racks), immediately after the founding of stability and stability, the vehicle and operation did not have much impact; follow-up expectations in close contact with the original Under the cooperation, the system is expected to gradually stabilize and reach the best goal of demonstration operation.
(Seven) this stage filter efficiency evaluation
1. Discuss the overall horsepower ratio of installing the soot filter. 20 cars 8 times (160 vehicles in total) There were 16 horsepower ratios (10.0%), 21 horsepower ratios (13.1%) and 26 vehicles Horsepower ratio of 2% (16.3%), 16 horsepower ratio of 3% (10.0%), 20 horsepower ratio of 4% (12.5%), 12 horsepower ratio of 5% (accounting for 7.5%), 17 horsepower to 6% (10.6%), 11 horsepower to 7% (6.9%), 9 horsepower to 8% (5.6%), horsepower ratio 9 % And 10% each 6 vehicles (3.8% each).
2.20 smoke filter vehicles installed after the average removal rate of 98% of black smoke. Before installation, the maximum value of opacity was 5.3 m-1, the minimum value was 0.1 m-1 and the average value was 0.9 m-1. Immediately after the installation of the soot filter in 20 vehicles, the first opacity Are 0; the second test of 4 car opacity measured value of 0.1 m-1, the remaining 16 are 0; the third regular test of a car opacity measured value of 0.2 m- 1, there are 5 car opacity measured value of 0.1 m-1, the remaining 14 are 0; 4 times a regular test of a car opacity measured 0.3 m-1,2 cars do not Light transmission rate of 0.2 m-1, 2 vehicles with a light transmittance of 0.1 m-1, the remaining 15 are 0; the fifth regular test of a vehicle opacity measured as 0.2 m-1, 3 vehicles with 0.1 m-1 of opacity, and 0 of the remaining 16 vehicles. The 6th periodic inspection had a vehicle with a light transmittance of 0.2 m-1 1 car opacity measured 0.1 m-1, the remaining 18 are 0; the seventh regular inspection of a car is not measured light transmittance of 0.2 m-1, 3 car opacity The measured value is 0.1 m-1, and the remaining 16 are all 0. The 8th periodic inspection has a vehicle with a light transmittance of 0.4 m-1 and 3 vehicles with a light transmittance of 0.1 m -1, the remaining 16 are 0.
3. In this project, 20 vehicles with soot filter installed had an average removal rate of 98% of black smoke after installation. Among them, 10 vehicles were tested for 8 times of opacity (average to 2 decimal places) Not 0.00 m-1, respectively 0.04,0.01,0.11,0.01,0.05,0.04,0.01,0.09,0.04 and 0.10 (m-1), because of its installation before the measurement of light transmittance were 0.6,1.8, The removal efficiencies were 94, 99, 98, 100, 93, 95, 100, 93% , 98% and 92%, the remaining 10 removal rates were 100%.
4. The project plans to install 20 garbage trucks, with an average annual mileage of 8,346 Km and a reduction of 116.1 (kg / yr) PM10 and a reduction of PM2.5 of 99.8 (kg / yr).
