Description
Technical Field
The utility model belongs to the technical field of flue gas detection equipment, concretely relates to prevent device of gas that flows fast in flue
Background
Coal occupies about 60% of the primary energy generating capacity in China, and occupies an irreplaceable position in social production. The main power generation form of coal is power generation through combustion in a boiler, although the pulverized coal combustion technology in the boiler is quite mature, the problems of insufficient combustion and the like still exist, and the detection of gas components in a flue reflects the internal combustion condition of the boiler. However, the flow rate of the flue gas is too high, so that the components of the flue gas cannot be detected. The device for uniformly reducing the rapid gas in the flue plays a crucial role in detecting the components of the flue gas.
Disclosure of Invention
The utility model provides a thereby can prevent the flue gas fast flow to obtain the device in stable flue gas flow field.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the detection unit comprises a detection unit and is characterized by further comprising a flow blocking device, the detection unit comprises a sampling tube, the flow blocking device is arranged at the end of the sampling tube, and the detection unit can stably detect the gas flowing fast in the flue under the prevention of the flow blocking device.
Preferably, the flow blocking device is a flow blocking cowl.
Preferably, the flow blocking cover is of a circular cylindrical structure with notches on side walls.
Preferably, the spoiler is provided with an opening at the windward side.
Preferably, the openings are four groups, each group of openings is provided with a plurality of holes, and the holes are arranged at intervals of 6mm along the axial direction of the flow resisting cover.
Preferably, the two groups of openings located in the center of the spoiler are at an angle of 50 ° with respect to the spoiler center, and the two groups of openings located on both sides of the spoiler are at an angle of 130 ° with respect to the spoiler center.
Preferably, the opening has a diameter of 2 mm.
Preferably, each set of said openings has 6 holes.
Compared with the prior art, the utility model has the advantages that the flow blocking cover is added on the head of the flue gas measurement and detection device, so that the flue gas to be measured can easily enter the measurement device, and the obtained flue gas flow field is stable, so that the detection of the flue gas components is more accurate.

Detailed Description
Make the purpose, technical scheme and advantage of the embodiment of the utility model more clear, will combine below in the embodiment of the utility model the drawing, it is right to technical scheme in the embodiment of the utility model carries out clear, completely the description.
Referring to fig. 1 to 4, in an embodiment of the present invention, the device for preventing fast flowing gas in a flue includes a detection unit 1, and further includes a flow blocking device 2, the detection unit 1 includes a sampling tube, the end of the sampling tube is provided with the flow blocking device 2, and under the prevention of the flow blocking device 2, the detection unit 1 can stably detect fast flowing gas in the flue 3.
In one example, the choke 2 is a choke 5.
In one example, the spoiler 5 is a circular cylindrical structure with notches 6 in the side walls.
In one example, the spoiler 5 is provided with an aperture 4 at the windward side.
In one example, the openings 4 have four sets, and each set of the openings 4 has a plurality of holes arranged at intervals of 6mm in the axial direction of the choke 5.
In one example, the two groups of openings 4 located in the middle of the spoiler 5 have an angle of 50 ° with respect to the center of the spoiler 5, and the two groups of openings 4 located on both sides of the spoiler 5 have an angle of 130 ° with respect to the center of the spoiler 5.
In one example, the opening 4 is 2mm in diameter.
In one example, each set of said openings 4 has 6 holes.
The choked flow cover that sets up at the measuring device head influences the flow field comparatively obviously, and the choked flow cover plays bluff body-like's effect in the flue, all has obvious backward flow district to exist at choked flow cover windward side and leeward side, and leeward side backward flow district is more obvious, and the flue gas is when the backward flow district is crossed to the flue gas, and dwell time increases.
The utility model discloses increased the choked flow cover at the measuring device head to make the volume of awaiting measuring flue gas get into the measuring device the inside easily, and the flue gas flow field that obtains is stable.
The above description is only for explaining the present invention, so that the person skilled in the art can completely implement the present invention, but not for limiting the present invention, and after reading the present specification, the person skilled in the art can make modifications to the present embodiment as required without inventive contribution, which are all modifications without inventive. But are protected by the patent statutes within the scope of the appended claims.
