Multichannel routing inspection type diesel engine tail gas detection device

Abstract

The invention discloses a multichannel routing inspection type diesel engine tail gas detection device. A plurality of cooling filters are connected with a gas distributor. A computer controls the gas distributor to gate one channel of gas to conduct the follow-up filtering analysis processing. The gas distributor is connected with a gas filter component and a gas analysis sensor component. The multichannel routing inspection type diesel engine tail gas detection device has the advantages that sampling gases exhausted from a diesel engine tail gas exhaust pipe is sent to the gas distributor after passing through the cooling filters; the gas distributor is controlled through the computer to gate the channel of the gas from the multiple channels to conduct the follow-up processing; the gated gas is subjected to moisture separation through an air filter, and filtered air enters a nondispersive infrared sensor after being further decontaminated and filtered through a dust filter; and the collection of components of oxygen, nitric oxide, nitrogen dioxide and sulfur dioxide is conducted through an electrochemical sensor in a gas analysis cavity, and then the sampling gases are exhausted through an exhausting device.

Description

Technical field [0001] The invention relates to a monitoring device for the exhaust emission of marine diesel engines. The device can be used in the operating environment of a single or multiple marine diesel engines without moving the device to monitor the exhaust emissions of diesel engines, and is suitable for monitoring exhaust emissions of various marine diesel engines. , Measuring and warning devices. Background technique [0002] Diesel engines are commonly used as prime movers in the marine field. Compared with prime movers in other fields, marine diesel engines have a larger installed capacity, and most ships use multiple diesel engines per ship. Diesel engine exhaust emissions have serious pollution to the atmosphere, and the scope of pollution will also expand due to the activities of ships. [0003] The main components in the exhaust gas of diesel engines are carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), hydrocarbons (HC) and p...

AI Technical Summary

Problems solved by technology

After the diesel engine is put into use, the internal structure of the diesel engine is worn out, the operating environment changes, and the quality of the fuel is different. The exhaust emission index will change accordingly, resulting in the loss of control of exhaust emission pollution.

If you want to control the exhaust emission of diesel engines in operation, you need to carry out the bench test again, or install a huge monitoring device on the ship to disassemble and measure the diesel engines one by one, which is extremely inconvenient
