Description

Technical Field

[0001] The invention relates to the technical field of flue gas desulfurization systems, in particular to a desulfurization tower sampling device. Background Art

[0002] A desulfurization tower is a device used to remove sulfur dioxide from combustion exhaust gas. Its working principle is mainly divided into two processes: absorption and reaction. During the absorption process, the combustion exhaust gas contacts the desulfurizer (usually an alkaline solution, such as sodium hydroxide or lime slurry) through a sprinkler or atomizer, and sulfur dioxide reacts chemically with the desulfurizer to form sulfate, which is then absorbed. During the operation of the desulfurization tower, we need to monitor a variety of parameters to ensure its stable operation, such as desulfurization efficiency, absorbent utilization efficiency and calcium-sulfur ratio, flue gas emission temperature and system pressure, water consumption and liquid-gas ratio, etc., so it is necessary to frequently sample and analyze the products in the desulfurization tower.

[0003] When sampling at the outlet flue, if we want to analyze the gaseous pollutants in the flue, we usually need to remove the particulate matter in the flue by filtering. However, we also need to analyze the composition of the byproducts from the fly ash carried in the flue to determine the operation status. The flue changes rapidly and the sampling process is complicated. Therefore, we need a device that is convenient for sampling and can separate the fly ash and flue gas in the flue.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1, reference Figure 1 to Figure 2, which is the first embodiment of the present invention, and provides a desulfurization tower sampling device, which includes an outer cylinder component 100, which includes a bearing part 101 and a connecting cover 102 arranged on the top of the bearing part 101, the bearing part 101 carries the accessories required by the device, and the connecting cover 102 connects the bearing part 101 with the flue gas channel of the desulfurization tower; and an opening and closing component 200, which includes a partition mechanism 201, a control mechanism 202 arranged on the side of the partition mechanism 201 and a protective layer 203 arranged at the bottom of the partition mechanism 201, and the partition mechanism 20 1 can close or open the connection between the subsequent sampling structure and the smoke channel, cut off the connection when not working, protect the components in the device and extend the service life; and, an ash taking component 300, which includes a carrier plate 301 and a support ring 302 arranged at the bottom of the carrier plate 301, and the ash taking component 300 filters out the fly ash entrained in the smoke to facilitate component analysis; and, a smoke taking component 400, which includes a smoke bag 401 and a connecting tube 402 arranged on the side of the smoke bag 401, and the smoke taking component 400 takes out the smoke for storage for subsequent detection.

[0026] Specifically, the sampling device connects the bearing part 101 with the flue gas channel of the desulfurization tower through the connecting cover 102. When not working, the opening and closing component 200 cuts off the connection between the device and the flue gas channel to protect the components in the device. When working, the opening and closing component 200 opens to allow the flue gas in the flue gas channel to enter the subsequent structure of the bearing part 101. The ash collecting component 300 filters out the fly ash entrained in the flue gas to facilitate component analysis. The smoke collecting component 400 takes out the flue gas for preservation for subsequent testing.

[0027] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, a connecting hole 103 is provided on the outer wall of the connecting cover 102. The outer cylinder component 100 is connected to the smoke channel through the connecting hole 103 by a connecting piece such as a bolt. A piston plate 104 is provided inside the bearing portion 101. An operating rod 105 is provided at the bottom of the piston plate 104. The bottom end of the operating rod 105 extends out of the bearing portion 101. The operating rod 105 can drive the piston plate 104 to slide in the bearing portion 101. The bearing portion 101 includes a bearing tube 101a. A straight groove 101b is provided on the inner wall of the bearing tube 101a. An inclined groove 101c is provided at the bottom of the straight groove 101b.

[0028] Furthermore, the partition mechanism 201 includes a rotating ring 201a disposed inside the carrier tube 101a, the rotating ring 201a is rotatably connected to the carrier tube 101a, and can rotate on the inner wall of the carrier tube 101a, the cross section of the rotating ring 201a is C-shaped, the inner wall of the rotating ring 201a is provided with an isolation frame 201b, and the interior of the isolation frame 201b is provided with a rotating plate 201c, and the number of the rotating plates 201c is plural, and they are distributed in a circular array on the isolation frame 201b with the axis of the carrier tube 101a, and the rotating plates 201c are arranged on the isolation frame 201b. Plate 201c can rotate on the isolation frame 201b. A gear 201d is set on the side of the rotating plate 201c. A tooth groove 201e is opened inside the rotating ring 201a. The tooth groove 201e is engaged with the gear 201d. The rotation of the rotating ring 201a will drive the gear 201d to rotate, thereby driving the rotating plate 201c to rotate. When the rotating plate 201c coincides with the isolation frame 201b, the isolation frame 201b will be closed, cutting off the connection between the upper and lower parts of the supporting tube 101a, thereby protecting the sampling accessories in the lower part.

[0029] Furthermore, the control mechanism 202 includes a slide plate 202a arranged inside the supporting tube 101a, and the slide plate 202a is slidably connected to the inner wall of the supporting tube 101a, and can slide on the inner wall of the supporting tube 101a. The outer wall of the slide plate 202a is provided with an arc groove 202b, and the side of the rotating ring 201a is provided with a slide bar 201f. The outer wall of the slide bar 201f is in contact with the arc groove 202b. The slide plate 202a slides up and down, which drives the slide bar 201f to rotate through the arc groove 202b, thereby driving the rotating ring 201a to rotate, so as to manipulate the rotating plate 201c to control the opening and closing of the partition mechanism 201.

[0030] Further, a side of the slide 202a is provided with a stop plate 202c, and a connecting arc plate 202d is provided on the side of the stop plate 202c close to the slide 202a. The connecting arc plate 202d is made of elastic material, and an annular clamping column 202e is provided at the bottom of the connecting arc plate 202d. A sliding groove 406 is provided inside the annular clamping column 202e, and a positioning block 202f is provided inside the annular clamping column 202e. The top of the positioning block 202f is connected to the slide 202a. Preferably, the positioning block 202f is obliquely arranged at the bottom of the slide 202a and kept parallel to the oblique groove 101c. Due to the sliding of the annular clamping column 202e The contour of the groove 406 coincides with the contour of the positioning block 202f, and the annular clamping column 202e can slide along the oblique direction of the positioning block 202f. When the slide plate 202a slides and drives the annular clamping column 202e to reach the mouth of the inclined groove 101c, the annular clamping column 202e can slide into the inclined groove 101c. A first elastic member 202g is provided at the bottom of the positioning block 202f. The bottom of the first elastic member 202g is connected to the interior of the annular clamping column 202e. The first elastic member 202g is in a compressed state. A through hole 303 is provided on the outer wall of the carrier plate 301, and a pressure ring 304 is provided inside the carrier plate 301.

[0031] Specifically, since the supporting tube 101a of the outer tube component 100 is always connected and communicated with the flue gas duct through the connecting cover 102, the sampling component at the bottom of the supporting tube 101a needs to be isolated from the flue gas duct when no sampling is performed, so as to protect the mechanism therein and prevent it from being corroded by the flue gas. At this time, the top of the piston plate 104 abuts against the protective layer 203, and an opening is provided on the surface of the protective layer 203. At this time, the rotating plate 201c overlaps with the isolation frame 201b, which will close the isolation frame 201b, cut off the connection between the upper and lower parts of the supporting tube 101a, and protect the sampling accessories in the lower part.

[0032] When sampling is required, the operating rod 105 can be pulled downward to drive the piston plate 104 to slide down, extracting the air at the bottom of the carrier tube 101a, forming a negative pressure in the carrier tube 101a, and the smoke will enter the carrier tube 101a from the smoke channel. At this time, the bottom of the piston plate 104 will apply a thrust to the annular clamping column 202e, driving the annular clamping column 202e and the slide plate 202a to slide down together, so that the slide plate 202a drives the rotating ring 201a to rotate through the arc groove 202b, thereby driving the gear 201d to rotate, and driving the rotating plate 201c to rotate, so that the rotating plate 201c and the isolation are no longer overlapped. When the slide plate 202a slides down with the annular clamping column 202e to the inclined groove 10 1c port, the first elastic member 202g will push the annular clamping column 202e into the inclined groove 101c port. At this time, the movement routes of the annular clamping column 202e and the piston plate 104 are staggered, and the annular clamping column 202e is stuck in the inclined groove 101c, so that the slide plate 202a and the rotating plate 201c cannot move, and the rotating plate 201c maintains the angle formed with the isolation frame 201b, and the smoke can pass through the isolation frame 201b to the sampling component at the bottom of the supporting tube 101a for sampling. Filter paper is placed in the supporting plate 301, and the filter paper is pressed in the supporting plate 301 by the pressing ring 304. When the smoke passes through the supporting plate 301, the dust in the smoke will be trapped on the filter paper, and the dust on the filter paper will be analyzed later.

[0033] When sampling is completed, push the operating rod 105 upwards, and when the top of the piston plate 104 is released from the abutment plate 202c, the abutment plate 202c pulls the annular clamping column 202e out of the inclined groove 101c through the connecting arc plate 202d. At this time, the upward sliding of the piston plate 104 will drive the slide plate 202a to move upward together, and the arc groove 202b on the slide plate 202a will drive the rotating plate 201c to rotate and overlap with the isolation frame 201b, isolating the upper part of the supporting tube 101a from the lower part, and the smoke no longer reaches the sampling component, thereby protecting the components therein.

[0034] Example 3, reference Figures 1 to 5, which is the third embodiment of the present invention. Different from the previous embodiment, the connecting tube 402 is in contact with the carrying tube 101a, and the connecting tube 402 and the carrying tube 101a are snap-fitted, so that the cigarette bag 401 can be connected to the outer wall of the carrying tube 101a, and the cigarette bag 401 is connected to the carrying tube 101a. A sliding cover 403 is arranged on the side of the connecting tube 402, and a support plate 404 is arranged at the bottom of the sliding cover 403. A sliding groove 406 is provided at the bottom of the support plate 404. The sliding groove 406 is provided on the inner wall of the carrying tube 101a. The support plate 404 can slide up and down on the inner wall of the carrying tube 101a together with the sliding cover 403. A second elastic member 405 is arranged inside the sliding groove 406. The second elastic member 405 is in a compressed state, and the second elastic member 405 is connected to the support plate 404.

[0035] Specifically, when sampling, the operating rod 105 is pulled downward to open the opening and closing component 200, and the piston plate 104 continues to slide down. The bottom of the piston plate 104 will contact the support plate 404, and the piston plate 104 will drive the support plate 404 to slide down, and the sliding cover 403 will slide down. At this time, the cigarette bag 401 is connected to the supporting tube 101a, and the smoke filtered by the filter paper can enter the cigarette bag 401, and the smoke is collected for subsequent analysis. When the sampling is completed, the piston plate 104 slides up and separates from the support plate 404, and the second elastic member 405 will push the sliding cover 403 and the support plate 404 upward together, and the sliding cover 403 covers the connecting tube 402 of the cigarette bag 401 again, and the cigarette bag 401 is closed.
