VOC (volatile organic compound) online monitor for organic acid environment

Abstract

The invention relates to the field of environment monitoring and particularly relates to a VOC (volatile organic compound) online monitor for an organic acid environment. The monitor comprises a monitor body, wherein a display screen is fixedly mounted at an upper part of a front end of the monitor body, and a first filter screen is fixedly mounted at a lower part of the front end of the monitor body; a shielding plate baffle is hinged to the position, corresponding to the first filter screen, of the inner surface of a front end of the monitor body, an alarm is fixedly installed on the upper portion of an outer surface of the right side of the monitor body, and a signal receiver is fixedly installed on the position, close to the left side, of an outer surface of the upper end of the monitor body; a wind power is utilized to push the shielding plate to move so as to enable the shielding plate to pull the pull rope, the pull rope is utilized to pull the sampling pump to rotate, and severe convection air is sucked into the pump body by the sampling pump, so difficulty in severe convection air monitoring is solved, and the monitoring capability is enhanced; and a wind indicator is used for enabling severe convection air from different directions to enter the monitor body through the first filter screen to monitor VOC.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an online VOC monitor for organic acid environments. Background technique [0002] Air pollution has affected people's lives, among which VOC is one of the important factors of air pollution. The VOC online monitor is an instrument and equipment for monitoring VOC. Refers to VOC, these volatile organic compounds include: formaldehyde, ammonia, ethylene glycol, esters, benzene and other substances. [0003] The existing patent (notification number: CN208580078U) VOC monitor includes a device main body and a contact seat. A digital display screen is arranged on the front end outer surface of the device main body near the upper position, and the front end outer surface of the device main body is close to the digital display screen. An operation panel is provided at the lower position of the operation panel, and a mode button is provided at the middle position of the inner su...

Problems solved by technology

[0006] The purpose of the present invention is to provide a VOC online monitor for organic acid environment, use the wind force to push the shutter to move and then make the shutter pull the pull rope, use the pull rope to pull the sampling pump to rotate, so that the strong convective air is sucked into the pump by the sampling pump In the body, this solves the difficulties faced in the monitoring of strong convective air, enhances the monitoring ability, and uses the wind vane to allow strong convective air from different directions to enter the interior of the monitor body through the first filter to monitor VOC. To solve the problems raised in the above-mentioned background technology
