Description

Technical Field

[0001] The invention relates to the technical field of boiler testing and various flue gas testing, and in particular to a dewatering, filtering and anti-clogging device for flue gas sampling. Background Art

[0002] During the performance test and environmental test of coal-fired boilers, it is often necessary to extract the flue gas in the flue for flue gas analysis. There are many flue equipment at the tail of coal-fired boilers. In order to test the flue gas composition at different positions and for the convenience of testing, engineering and technical personnel often place the test instruments in a fixed position and extract the flue gas in various flues through rubber tubes into the flue gas analyzer for flue gas analysis. Since the flues at different positions are far apart and have a large height difference, sometimes the height difference even exceeds 50 meters, the end of the longer rubber tube can usually only be wrapped around the railing for fixing. Since the middle is almost suspended in the air, the part where the rubber tube is hung on the railing is easily flattened by its own weight, causing the pipeline to be blocked, which brings inconvenience to the test. Summary of the invention

[0003] The purpose of the present invention is to provide a dewatering, filtering and anti-clogging device for flue gas sampling, which is particularly suitable for coal-fired boiler testing.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

When the first locking hook and the second locking hook are locked, the switch component keeps the drain valve in an open state.

[0010] Still further preferably, the maximum suspension height of the second suspension member is lower than the maximum suspension height of the first suspension member.

[0011] Further preferably, one end of the smoke inlet pipe extends into the water storage tank, and one end of the smoke inlet pipe forms a beveled opening.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 As shown, a dewatering, filtering and anti-clogging device for flue gas sampling includes a smoke inlet pipe 1, a dewatering mechanism, a hanging component 3, a filtering mechanism, and a smoke outlet pipe 5 connected in sequence. The hanging component 3 is made of a rigid material to avoid pipeline blockage when the device is hung on a horizontal railing on site. The smoke inlet pipe 1 and the smoke outlet pipe 5 are connected to an exhaust hose.

[0023] The water removal mechanism includes a water tank 21, a drain valve 22 arranged on the water tank 21, an automatic switch assembly arranged in the water tank 21, and a water tank interface 29 arranged on the top of the water tank 21. The automatic switch assembly cooperates with the drain valve 22 to control its opening and closing. The water tank interface 29 connects the water tank 21 with the flue gas inlet pipe 1 and the hanging component 3. The material of the water tank 21 is organic glass, and the material of the water tank interface 29 is 304 stainless steel, and the two are connected by threads. The drain valve 22 is arranged at the lower part of the tank wall of the water tank 21, and the material is 304 stainless steel. After the high-temperature flue gas flows through the flue gas inlet pipe 1 and enters the water tank 21, the water vapor is condensed into liquid and accumulated under the influence of the room temperature. The water removal mechanism can also add a water absorption component 28 in the water tank 21, such as granular water-removing silica gel, etc., to assist in water absorption.

[0024] The automatic opening and closing assembly includes a first suspension member 231, a switch rod 25 connected to the first suspension member 231 at one end, a first lock hook 241 arranged at the outlet of the drain valve 22 on the water storage tank 21, a connecting rod 26 rotatably connected to the switch rod 25 in the middle, a second suspension member 232 connected to one end of the connecting rod 26, and a second lock hook 242 connected to the other end of the connecting rod 26. The other end of the switch rod 25 is connected to the water storage tank 21. Preferably, the other end of the switch rod 25 is rotatably connected to the corner of the bottom of the water storage tank 21 near the drain valve 22. A switch member 27 is arranged on one of the switch rod 25 and the drain valve 22. When the water level rises, the first suspension member 231 drives the switch rod 25 to push the switch member 27 to open the drain valve 22. Preferably, the switch member 27 is arranged on the drain valve 22. After the water level rises, the second suspension member 232 floats up, and the second lock hook 242 is locked with the first lock hook 241 through the connecting rod 26, so that the switch rod 25 can be kept stable, and the switch member 27 can be continuously pushed to open the drain valve 22. The maximum suspension height of the second suspension member 232 is lower than the maximum suspension height of the first suspension member 231, so that when the water level is lower than the first suspension member 231 and higher than the second suspension member 232, the second lock hook 242 maintains the locking state with the first lock hook 241 under the buoyancy of the second suspension member 232. When the water level is lower than the second suspension member 232, the second suspension member 232 rotates through the connecting rod 26 to drive the second lock hook 242 and the first lock hook 241 to disengage. The valve of the drain valve 22 is provided with an elastic member 221, which always gives an elastic force to close the valve of the drain valve 22. When the first lock hook 241 and the second lock hook 242 are disengaged, the valve of the drain valve 22 is closed under the action of the elastic force. The valve of the drain valve 22 is provided with a sealing member made of silicone, and the drain valve 22 and the water storage tank 21 are tightly combined under the action of the elastic member 221, so that the water storage tank 21 is sealed. The first suspension member 231 and the second suspension member 232 are light floating objects, the first lock hook 241, the second lock hook 242, and the switch rod 25 are made of 304 stainless steel, and the elastic member 221 is made of spring steel.

[0025] The filter mechanism includes a filter tank 41, a filter material 42 filled in the filter tank 41, and a filter tank interface 43 arranged on the top of the filter tank 41. The filter tank interface 43 is made of 304 stainless steel to facilitate the replacement of the filter material 42. The filter material 42 can be selected from filter cotton, etc. The hanging component 3 is connected to the filter tank interface 43, and the smoke outlet pipe 5 is welded to the bottom of the filter tank 41. The smoke outlet pipe 5 is made of 304 stainless steel.

[0026] The smoke inlet pipe 1 and the hanging component 3 are U-shaped pipes for convenient hanging and avoid being bent, and the material is 304 stainless steel. One end of the smoke inlet pipe 1 is welded and fixed on the plane of the water tank interface 29, and extends into the tank, and the end of one end forms a bevel mouth, so that the accumulated water quickly drips into the water tank 21, thereby separating from the smoke.

[0027] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
