Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023]The invention is a novel low-temperature plasma generator cooperative particle sampling device for treating harmful emissions from diesel engines. During the test, first connect the high-voltage electrodes 2 and low-voltage electrodes 11 of three or more plasma generators in parallel by soldering or winding connecting rods, then connect the high-voltage electrodes to the variable-frequency and variable-voltage plasma power supply, and ground the low-voltage electrodes to Plasma is generated. The total exhaust pipe 1, the total exhaust pipe 20 are connected with the exhaust device with a silicone tube. The exhaust gas of the diesel engine is first connected to the main exhaust pipe 1, the valve A8 is rotated, the valve A8 is opened, and the particle sampling device A10 starts to obtain the particle sample. Particulate matter samples b...

Abstract

The invention discloses a sampling device of collaborative particulates of a low-temperature plasma generator and a sampling method and relates to the technical field of purification treatment of harmful exhaust gas of cars. The sampling device comprises a main gas inlet pipe (1), a bracket A (5), the low-temperature plasma generator (6), a gas inlet pipe (7), a particulate sampling device A (10), a particulate sampling device B (14), a gas exhausting pipe (17), a bracket B (18), a total gas exhausting pipe (20) and a base (21). The sampling device and the sampling method disclosed by the invention have the advantages that by combination of the particulate sampling device, a particulate sample before low-temperature plasma treatment can be obtained by opening a valve A (8), and a particulate sample after low-temperature plasma treatment can be obtained by opening a valve B (16). The sampling device and the sampling method can be used for testing and analyzing the particulate sample before and after action of the low-temperature plasma so as to obtain the action rule of the low-temperature plasma on the particulates. The sampling device provides convenient conditions for studying the action mechanism of the particulates by low-temperature plasma treatment.

Description

technical field [0001] The invention relates to the technical field of purification treatment of harmful exhaust gas from diesel engines. Background technique [0002] A few days ago, serious "smog" phenomenon appeared in many areas of China, causing significant negative impact on the environment, human health and economy. Studies have found that inhalable particulate matter is the main cause of "smog". Therefore, the primary task of solving "smog" pollution is to effectively control inhalable particulate matter. Studies have shown that low-temperature plasma can effectively reduce particulate matter emissions without causing secondary pollution. The low-temperature plasma generator is mainly composed of a plasma power supply, a high-voltage electrode, a dielectric layer and a low-voltage electrode. Among them, the high-voltage electrode is connected to the plasma power supply, the low-voltage electrode is grounded, and the dielectric layer is placed between the two elect...
