Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0022] Such as figure 1 As shown, the multi-channel inspection type diesel engine exhaust gas detection device includes a plurality of cooling filters connected with the diesel exhaust exhaust pipe 1, a computer-controlled gas distributor 2, a gas filter assembly and a gas analysis sensor assembly, and a plurality of cooling The filter 1 is connected to the gas distributor 2. The computer controlled gas distributor 2 selects one of the gases for subsequent filtering and analysis processing, and the gas distributor 2 is connected to the gas filter assembly and the gas analysis sensor assembly. The function of the cooling filter 1 is to cool the sampled gas and prevent subsequent components from being damaged due to the high temperature of the sampled gas. At the same time, a filter element is installed inside the device to filter large particles in the sampl...

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...
