Novel monitor

Abstract

The invention relates to a novel monitor, comprising a dust filter, a long-path gas adsorption cell, a light source emitter and a host machine. Specifically, the dust filter and the long-path gas adsorption cell are in rotational connection, the long-path gas adsorption cell is connected to the light source emitter through a fixation device, a triangular-pyramid total reflection mirror is arranged in the front of the long-path gas adsorption cell, and the light source emitter is in connection with the host machine by a communication link. The host machine of the monitor consists of a gas extraction and control module, a data display module and a wireless sending and receiving module. The invention discloses a monitor for odor gases of fugitive emission sources like dimethyl sulfide, methyl mercaptan, ammonia gas, hydrogen sulfide, methylamine, dimethyl disulfide, styrene, carbon disulfide, etc. With a portable structural design, the monitor of the invention can be used for direct on-site tests, and can avoid complex processes like gas extraction sampling, transportation, dilution, olfactory discrimination, etc., as well as can reduce the labor intensity of the staff.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a novel monitoring instrument. Background technique [0002] The traditional malodorous gas monitoring method is the extraction-sniffing method, that is, the technician uses a gas sampler to extract the malodorous gas into a special air bag, and after returning to the laboratory, the olfactory expert who has been trained and issued a qualification certificate conducts the olfactory determination , according to the number of dilutions to determine the poisonous level of the malodorous gas. Because malodorous gases are usually mixtures, human sense of smell cannot distinguish the components of malodorous gases, and cannot provide accurate material composition, so it is impossible to formulate corresponding control measures; another important point is that the composition of malodorous gases is unknown, and often harmful to human body. Toxic substances that pose a hazard to the health of work...
