Problems solved by technology

[0003] The purpose of the present invention is to provide a gas pollution monitoring instrument. Through the main air pipe and the base, the two side air intake pipes can simultaneously sample the air in the windward direction and the leeward direction; The air sample with homogeneous wind avoids the influence of wind force on the collection of air samples, which effectively solves the problem of uneven pollutant content in air samples in the windward and leeward directions and inaccurate air monitoring; through the spring and the ring-shaped trachea cover, it can be mixed The air is sealed to maximize the retention of sufficient air samples, and at the same time, it can ensure that the air samples in the windward direction and the leeward direction are collected and mixed at the same time.

Abstract

The invention relates to the technical field of gas pollution monitoring, in particular to a gas pollution monitoring instrument. The gas pollution monitoring instrument comprises a main gas pipe, lateral gas inlet pipes, a mixed flow assembly and a base, wherein the lateral gas inlet pipes are fixedly connected to the left end and the right end of the main gas pipe respectively; the mixed flow assembly is rotationally connected at the upper end of the main gas pipe; both the lateral gas inlet pipes are in transmission connection with the mixed flow assembly through a gear; the main gas pipe is rotationally connected on the base. According to the gas pollution monitoring instrument, through the main gas pipe and the base, the two lateral gas inlet pipes can simultaneously sample air in thewindward direction and the leeward direction; by simulating windless and homogeneous air samples, it is avoided that wind power influences on collection of the air samples, and the problems that thepollutant content of the air samples in the windward direction and the leeward direction is uneven, and air monitoring is inaccurate are effectively solved; mixed air can be sealed, sufficient air samples are furthest reserved, and meanwhile it can be guaranteed that the air samples in the windward direction and the leeward direction are collected and mixed at the same time.

Description

technical field [0001] The invention relates to the technical field of gas pollution monitoring, in particular to a gas pollution monitoring instrument. Background technique [0002] For example, the patent application number is CN201620257483.8, a multi-functional harmful gas monitor, which includes a shelf, a harmful gas monitor and a temperature and humidity monitor.
