Problems solved by technology

[0004] Automobile engine tests are divided into many types, including body test, function test, engine life test, etc. No matter what the method is, a large amount of exhaust gas is produced, especially for engine life tests, which are usually continuously started continuously until The purpose of the test is completed, and the exhaust gas is traditionally placed in a water body. The water pressure will cause pressure on the engine exhaust at this time, and if the water is too shallow, the exhaust gas will be discharged due to insufficient filtration of water, and it will not be able to deal with different types of exhaust gas. Emissions, resulting in uneven treatment of a large amount of waste gas, resulting in partial pollution, such as CO accumulation in the factory building or other local areas causing hidden dangers

Embodiment 1

[0034] Such as Figure 1-7 As shown, an engine exhaust gas online purification test system includes an exhaust partial pressure cylinder and an exhaust gas purification cylinder. Separation, discharge, and treatment are carried out in it, and the exhaust gas purification cylinder part is docked with the exhaust gas partial pressure cylinder part to treat the exhaust gas, and multi-stage exhaust gas purification treatment is performed to complete the final purification operation of the exhaust gas.

[0035] Such as Figure 1-5 As shown, the exhaust gas partial pressure cylinder part includes an annular pressure partial cylinder 1. The annular pressure partial pressure cylinder 1 is in the shape of a ring, and a support stand can be erected at the bottom, and the stand can also be used for fixing. Its main function is to fix it. Elevate the equipment outside to facilitate the movement and coordination between components. The material of the annular pressure divider 1 is made of...

Embodiment 2

[0043] Such as Figure 1-2 As shown, the middle section of the first pipeline 4 is disconnected to form a gap, the gap divides the first pipeline 4 into two, and is connected with a rubber ring cover 20, the rubber ring cover 20 connects the two sections of the gap, and the rubber ring cover 20 Existence, solving a problem at one end when exhaust gas is discharged can provide a temporary solution, so that the internal pressure of the first pipeline 4 will not be too large, and at the same time maintain a better guarantee effect.

Embodiment 3

[0045] Such as Figure 8-9 As shown, the outside of the self-weight pressure cylinder 5 is surrounded by a heating pipe 28, and the port of the heating pipe 28 is exposed. The inner wall of the self-weight pressure cylinder 5 contains a passage 29, and the heating pipe 28 is partly connected with the passage 29, and the passage 29 is connected with an exhaust fan. 21 and the three-way valve 19, under the action of the exhaust fan 21, the purification space 24 on the top and bottom layers can be connected through the channel 29, thereby forming a cycle so that the exhaust gas solution is continuously purified until it meets the discharge standard. The pipe 28 communicates with the three-way valve 19, and the inner wall of the heating pipe 28 can also be partly hollowed out, so that the outside air can enter, and the inside contains a spark plug. The space of the baffle plate 23 is connected, and a large amount of CO and a small part of sulfide are ignited inside the heating tub...

Abstract

The invention belongs to the technical field of tail gas purification, and particularly relates to an engine tail gas on-line purification test system which comprises a tail gas partial pressure cylinder part and a tail gas purification cylinder part, the tail gas partial pressure cylinder part is used for collecting and treating tail gas, and the tail gas purification cylinder part is in butt joint with the tail gas partial pressure cylinder part for treating the tail gas; the tail gas partial pressure cylinder part comprises an annular partial pressure cylinder, a driving mechanism is arranged in the middle of the annular partial pressure cylinder, a tail gas partition separation mechanism is arranged in the annular partial pressure cylinder, the driving mechanism is used for driving the tail gas partition separation mechanism to rotate, a multi-layer purification mechanism is arranged in the self-weight pressure cylinder, and the self-weight pressure cylinder is in butt joint with the driving mechanism; the engine tail gas online testing system has the advantages that the system is designed to conduct online testing on engine tail gas, a pressure-free negative pressure space can be provided when a large number of automobile tail gas is treated at the same time, the effect of not influencing a tested engine is achieved, meanwhile, the system can cope with various kinds of discharged waste gas, and therefore the waste gas treatment range is wider and more effective.

Description

technical field [0001] The invention belongs to the technical field of tail gas purification, and in particular relates to an engine tail gas online purification test system. Background technique [0002] Automobile exhaust is the exhaust gas produced during the use of automobiles. It contains hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. The exhaust gas is directly harmful to the environment. While improving human health, it will also have a profound impact on the environment in which human beings live. [0003] Carbon dioxide (CO2), sulfide SOx (SO and SO2), nitrogen oxides NOx (NO and NO2), chlorofluorocarbons, etc. emitted by automobiles make atmospheric environmental problems such as greenhouse effect, ozone layer destruction and acid rain more serious; Exhausted CO, NOx, SOx, unburned hydrocarbons HC, particulate matter PM and odorous gases poll...
