Embodiment 1

[0023] The embodiment of the present application provides a gas collection and measurement device, including a detector 16, an air supply device and a housing, the housing is provided with an enrichment groove 11, the detector 16 is arranged in the housing, and is connected with the enrichment groove 11 connected, the air delivery device is installed to the casing, and is used to send the gas 41 to be tested into the enrichment groove 11 .

[0024] The gas collection and measurement device provided in the embodiment of the present application changes the passive suction (negative pressure at the collection port) of the existing gas collection device to an active (+passive) gas collection method, which greatly improves the gas collection and measurement device. Acquisition efficiency and measurement accuracy.

[0025] In an exemplary embodiment, the housing includes a first housing 1 and a second housing 2, the first housing 1 is opposite to the second housing 2, and the first ...

Embodiment 2

[0046] This embodiment provides a gas collection and measurement device (including gas containing particulate matter such as smoke and dust), which differs from the first embodiment mainly in the structure of the housing.

[0047] In an exemplary embodiment, the housing includes a first housing 1, the enrichment groove 11 is arranged on the first side wall of the first housing 1, and the detector 16 is arranged in the first housing 1; the gas delivery device It includes an exhaust device 15 installed on the first housing 1 , and the exhaust device 15 sucks the gas to be measured 41 into the enrichment groove 11 . The ventilation device 15 can accelerate the speed at which the gas in the gas channel 3 enters the detector 16 .

[0048] The enrichment groove 11 is connected with an exhaust device 15 (for example: exhaust fan or suction pump, etc.), and is usually in a standby state. When the person or object 4 to be detected travels in the gas channel 3 and passes through the enr...

Abstract

The invention provides a gas collecting and measuring device which comprises a detector, a gas supply device and a shell, an enrichment groove is formed in the shell, the detector is arranged in the shell and connected with the enrichment groove, and the gas supply device is installed in the shell and used for sending gas to be measured into the enrichment groove. The gas collecting and measuringdevice provided by the embodiment of the invention is good in gas collection effect and high in measurement precision.

Description

technical field [0001] This application relates to but is not limited to the field of gas collection and monitoring, especially a gas collection and measurement device. Background technique [0002] Existing flue gas online monitoring equipment, industrial toxic gas monitoring equipment, anti-biochemical poisonous gas monitoring equipment and other equipment are generally independent detectors, which are directly hung or placed at the collection point according to the application, and the collection points are all attached to the detector The hole-shaped negative pressure collection port will not make additional design for the collection efficiency of the sample. For example: Smith Detection's sabre5000 trace industrial toxic gas detector, Tianjin Chaumet Technology Co., Ltd.'s CEMS-8000 smoke emission continuous monitoring system, the accuracy of these monitoring equipment still needs to be improved. Contents of the invention [0003] In order to solve at least one of th...
