Linear reciprocating type continuous online flue gas sampling detection device based on fixed position

Abstract

The invention discloses a linear reciprocating type continuous online flue gas sampling detection device based on a fixed position, the linear reciprocating type continuous online flue gas sampling detection device comprises a fixed mechanism and a motion sampling mechanism, a first end of the motion sampling mechanism penetrates into the fixed mechanism, a second end of the motion sampling mechanism penetrates out of a second end of the fixed mechanism, the outer wall of the moving sampling mechanism is in sealing fit with the inner wall of the fixing mechanism, a sampling air inlet end is arranged at the first end of the moving sampling mechanism, two or more sampling ends are arranged on the side wall of the fixing mechanism, the sampling air inlet end and the sampling ends correspond to each other in position, and the sampling air inlet end and the sampling ends correspond to each other in position, the first end of the fixing mechanism is inserted into the chimney. According to the invention, the outer pipe and the inner pipe are matched with each other, and the inner pipe linearly reciprocates in the outer pipe under the driving of the motor, so that the inner sampling hole and the corresponding outer sampling hole coincide to realize the conduction with fluid in the chimney, thereby achieving the purpose of multi-point continuous online sampling detection and reducing the manpower consumption.

Description

technical field [0001] The invention relates to the technical field of smoke detection. Specifically, it is a linear reciprocating continuous online smoke sampling and detection device based on a fixed position. Background technique [0002] Smoke detection is one of the common environmental detection items. In the actual detection, it is necessary for the detection personnel to carry the detection equipment to climb to the sampling hole of the chimney, and then insert the detection equipment into the sampling hole of the chimney, which requires a lot of manpower, and During the sampling inspection, due to the limited length of the bong and the limited manpower, and the large diameter of the chimney, only the flue gas at the side wall of the chimney can be sampled and detected during the inspection, and the flue gas at the center of the chimney cannot be sampled and detected, and manual inspection is required. The detection device can be moved multiple times to realize samp...
