Description

Technical Field

[0001] The utility model belongs to the technical field of boiler smoke detection, in particular to auxiliary equipment for boiler smoke detection. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. Boilers have greatly facilitated the development of social production both in industry and life, but there are pros and cons. The flue gas emitted by the boiler after combustion is extremely harmful to the environment and humans, so there are a series of standards for boiler emissions. Among them, there are emission requirements for sulfur dioxide, nitrogen oxides, carbon monoxide, dust particles, etc. in boiler flue gas, so it is necessary to test the boiler flue gas before emission.

[0003] The publication number is "CN117214393A" and the name is "A boiler flue gas detection device". A flue gas detection device is disclosed. It mainly solves the defect that the existing flue gas detection device cannot detect the temperature, sulfur dioxide and nitrogen oxide content and particulate matter concentration of the flue gas at different positions inside the chimney during the detection process by setting a conveyor belt. The detector position is adjusted by the linkage between the conveyor belts. However, the conveyor belt is located in the flue gas pipe, and solid impurities such as dust in the flue gas can easily cause jams between the conveyor belts. At the same time, due to the complex structure of the device, the probability of failure is relatively high. Utility Model Content
