Description

Technical Field

[0001] The utility model relates to the field of flue gas inspection, in particular to a component for capturing discharged flue gas. Background Art

[0002] There are strict requirements for discharged flue gas in production processes such as thermoelectricity and chemical industry. To test whether the flue gas emission index meets the standard, usually, a collection bundle tube is added to the discharge pipeline, and regular detection is carried out, combined with the form of random discharge sampling inspection. However, for the random discharge sampling inspection, gas needs to be directly collected at the discharge end. There are various risks for personnel to directly approach the discharged flue gas with detection equipment in hand, and the gas needs to be captured and then detected separately. The gas capture devices in the prior art generally have a relatively complex form, with the disadvantages of complex structure, high cost, and high requirements for the operating environment. Especially for discharged flue gas with lateral, oblique, or upward directions and different orientations of discharge ports, it is difficult for the gas capture port to directly face the discharged flue gas, and it is easy to have inaccurate samples during gas capture and exhaust. For the above problems, there is currently a lack of corresponding solutions. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a component for capturing discharged flue gas that can flexibly change the orientation of the gas collection port, is suitable for direct sampling from the discharge pipeline, and has a simple structure and low requirements for operating conditions.

[0004] The device includes a gas collection mask, and a gas collection hose is connected to the tail end of the gas collection mask;

[0005] A hose housing is sleeved on the outer wall of the gas collection pipe, and the hose housing is in the form of a curved rod;

[0006] The gas collection mask is hinged to the end of the curved pipe housing, that is, the end of the curved rod;

[0007] Lugs are oppositely arranged on the upper and lower surfaces of the gas collection mask; a plurality of fixed pulleys are arranged on the hose housing; a wire winder is arranged at the lower part of the hose housing;

[0008] Pulling ropes are arranged on the lugs. One end of each pulling rope is tied to the lug, and the other end passes through the fixed pulley and is wound on the wire winder.

[0009] The achieved effect is that by respectively pulling the pulling ropes on the upper and lower surfaces of the gas collection mask, the orientation of the gas collection mask can be adjusted, enabling the gas collection mask to be set downward, to the side, or obliquely, so as to fully correspond to the gas outlet of the exhaust pipeline.

[0010] The beneficial effects of the present utility model are as follows. The present utility model solves the problem in the prior art that it is difficult for gas collection equipment to align with the exhaust pipe opening, resulting in inaccurate collection samples. On this basis, the equipment structure is simpler, the operation requirements are low, the manufacturing cost and maintenance cost are low, and it has greater market promotion value.
