Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger cleaning, and in particular to a dust removal device for tubular heat exchangers. Background Technology

[0002] The technical problem of sludge buildup in tubular heat exchangers is mainly due to scaling caused by poor circulating water quality. Sludge deposits on the heat exchanger surface, forming an insulating layer that reduces heat transfer efficiency, increases pressure drop, and leads to increased energy consumption and reduced efficiency. The sludge deposits on the heat transfer surface also form an insulating layer, further reducing the heat transfer rate. To achieve the same output, the temperature or flow rate must be increased, thus increasing energy consumption.

[0003] During the cleaning of tubular heat exchangers, the pipes may become clogged with sludge. Using a high-pressure water gun for cleaning involves cleaning the entire tubing, resulting in significant water waste and inaccurate cleaning of the pipes' interior. This can leave sludge residue in the pipes, affecting subsequent use. Utility Model Content

[0028] Reference Figures 1-5 For the first embodiment of the utility model, provide a kind of ash removal device of tubular heat exchanger, it includes, clamping component 100, it includes several groups of clamping block 102 with the sliding fit of bottom disc 101, rotating disc 103 is formed to the limiting of clamping block 102, and cover plate 104 is arranged at the side of rotating disc 103 away from bottom disc 101, several groups of sliding grooves 101a are opened in the surface of bottom disc 101, limiting groove 101a-1 is opened in the side wall of sliding groove 101a, through slot 101b is opened in the inside of bottom disc 101, and discharge hole 101c is arranged in the bottom circumference of bottom disc 101.

[0029] Further, several groups of clamping block 102 are arc surface towards central plane, limiting block 102a is arranged on the two sides of clamping block 102, limiting block 102a and limiting groove 101a-1 are slidingly fitted, limiting column 102b is fixedly arranged on the side of clamping block 102 close to rotating disc 103, several groups of abutment grooves 103a are opened in the surface of rotating disc 103 and are arranged in the circumferential array, each abutment groove 103a is correspondingly limited with each limiting column 102b, each abutment groove 103a is from outer ring surface towards the position of axis, adjusting groove 104a is arranged on the side wall of cover plate 104, adjusting groove 104a limits the movement range of handle 103b, through hole K is opened in the center of bottom disc 101 and rotating disc 103 and is coaxial, and through hole K enters bottom disc 101 and is arranged through fixed disc 201.

[0030] Specifically, first, the rotation of rotating disc 103 is controlled by controlling handle 103b, when rotating disc 103 rotates, the abutment groove 103a on rotating disc 103 also rotates, because several groups of abutment grooves 103 are arranged in circumferential array, so when rotating disc 103 rotates, the tail end of abutment groove 103 is abutted and drives the rotation of limiting column 102b, when limiting column 102b rotates, clamping block 102 is horizontally slid along sliding groove 101a, at this time, limiting block 102a on the two sides of clamping block 102 is slid in limiting groove 101a-1, so as to limit the displacement range of limiting block 102a, it should be noted that, there is great friction between rotating disc 103 and bottom disc 101, so only the rotation of rotating disc 103 needs to be controlled in the process of clamping, rotating disc 103 does not rotate under the action of external force, cover plate 104 and base 101 can be connected by bolt, detachable setting is realized, subsequent replacement processing is facilitated, after clamping is completed, the position of discharge hole 101c is accurately corresponded with each pipeline of tubular heat exchanger.

[0031] Finally, the pipe heat exchanger is cleaned by the above method, and the rotating disc 103 is controlled by the handle 103b to make the clamping block 102 clamp the pipe of the pipe heat exchanger, so that each pipe can be accurately cleaned in the cleaning process. Embodiment 2

[0032] With reference to Figures 1-5 The second embodiment of the utility model is different from the previous embodiment, and further comprises a drainage groove 201a formed by the circumferential side wall of the fixed disc 201 and the cover plate 104, the fixed disc 201 is provided with a rotating groove 201b, the cleaning piece 202 comprises a cleaning rod 202a arranged through the rotating groove 201b, the cleaning rod 202a is provided with a limiting plate 202b on the side close to the rotating disc 103, and the limiting plate 202b cannot pass through the rotating groove 201b.

[0033] Further, the brush plate 202a-1 is threadedly arranged on the circumferential ring surface of the cleaning rod 202a.

[0034] Specifically, after the clamping assembly 100 and the pipe of the pipe heat exchanger are clamped, the cleaning rod 202 is also inserted into the inside of the pipe, at this time, water is added through the through hole K at the top cover plate 104, the water flow reaches the inside of the through groove 101b along the through hole K, and the water flow is discharged to the lower side of the fixed disc 201 through the drainage groove 201a of the circumferential side wall of the fixed disc 201, at this time, the water flow is discharged along the discharge hole 101c on the bottom disc 101, and the brush plate 202a-1 on the side wall of the cleaning rod 202a is contacted by the water flow in the process of discharging the water flow through the discharge hole 101c. Since the brush plate 202a-1 is threadedly extended downward along the cleaning rod 202a, at this time, the water flow contacts the brush plate 202a-1 and gives a certain force, the brush plate 202a-1 drives the cleaning rod 202a to rotate as a whole, since the limiting plate 202b above the cleaning rod 202a cannot pass through the rotating groove 201b, the cleaning rod 202a can only rotate in the circumferential direction when contacting the water flow, and the phenomenon of disengagement is not caused. It should be noted that the water flow rate can be controlled according to the degree of on-site sludge blockage in the water injection process, so as to achieve the best cleaning effect, and the handle 103b can be reversely rotated to achieve the unlocking effect after the cleaning process is completed.
