DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Example 1
[0022] See also Figure 1 and Figure 2The present invention provides a technical solution: when gas containing mist flows through the demister at a certain speed, the mist collides with the corrugated plate or wire mesh of the demister and is captured due to the inertial impact of the gas. As the mist droplets gather and grow, their gravity gradually increases. When the gravity exceeds the combined force of the gas's rising force and the liquid's surface tension, the droplets separate from the demister surface, achieving gas-liquid separation. A demister that is easy to clean internally includes a plurality of equidistantly installed demister blades 100 and a blade fixing frame 101. The top and bottom edges of the demisting blade 100 are fixed by a blade fixing frame 101. A screw mounting seat 200 is installed on the top of the blade fixing frame 101, and a threaded rod 204 is installed on the screw mounting seat 200. Limit rods 205 are also symmetrically installed on both sides of the top of the blade fixing frame 101. A cleaning scraper 201 is installed on multiple demisting blades 100, and a cleaning scraper 202 is provided on the cleaning scraper 201. A threaded seat 203 is installed on the top of the cleaning scraper 201. The top of the cleaning scraper 201 is symmetrically installed on both sides. The limited movable seat 206, when the demister has been used for a period of time, a lot of dust and impurities will be captured on the surface of the demister blade 100. Since the inner surface of the corrugated demister blade 100 is not convenient to clean, one end of the threaded rod 204 can be rotated at this time. When the threaded rod 204 rotates on the screw mounting seat 200, the threaded seat 203 is driven to move by the action of the threaded seat 203 and the thread. When the threaded seat 203 moves, it is also limited and guided by the action of the limited movable seat 206 and the limit rod 205, thereby ensuring cleaning. The scraper 201 has a stable structure. When the threaded seat 203 moves, it drives the cleaning scraper 201 to move, and the defogger blade 100 passes through the cleaning scraper 201. When the cleaning scraper 201 moves, the cleaning scraper 202 set at the penetration point will contact and scrape the surface of the defogger blade 100. The impurities on the surface of the defogger blade 100 are scraped off by the cleaning scraper 202, which is convenient for cleaning the surface of the internal defogger blade 100. It is convenient and quick and can also avoid the occurrence of cleaning dead corners, thereby improving the practicality and functionality of the device.
[0023] Specifically, the threaded rod 204 passes through the threaded seat 203 at the top of the cleaning scraper 201, and the threaded seat 203 and the threaded rod 204 are screwed together by a thread. The threaded screwing structure can be rotated and adjusted, and the cleaning scraper 201 can be driven to move back and forth during the rotation adjustment. The top of the cleaning scraper 201 is also limited by the symmetrical limit rod 205 and the limit moving seat 206 when moving, ensuring the stability of the cleaning scraper 201 during movement. A blade groove is provided on the cleaning scraper 201, and the demisting blade 100 passes through the cleaning scraper 201 through the blade groove, and the cleaning scraper 202 is correspondingly arranged on both sides of the blade groove and the cleaning scraper 202 also contacts the surface of the demisting blade 100. The contact can better scrape off impurities on the surface of the demisting blade 100. The surface of the cleaning scraper 201 is provided with multiple groups of cleaning scrapers 202, and each group of cleaning scrapers 202 corresponds to a demisting blade 100 to ensure the cleaning effect.
[0024] Example 2
[0025] See also Figure 1 and Figure 3 The present invention provides a technical solution: a demister that is easy to clean internally, wherein an air flow distribution plate 300 is fixedly installed on the screw mounting seat 200 directly below the demister blades 100, and the air flow distribution plate 300 includes an upper distribution plate 301 and a lower distribution plate 302, and the surface of the upper distribution plate 301 is provided with a through transverse distribution groove 311, and the surface of the lower distribution plate 302 is provided with a through longitudinal distribution groove 322. When the air flow passes through the bottom of the demister, the air flow will pass through the air flow distribution plate 300 in advance and be diverted by the lower distribution plate 302 and the upper distribution plate 301 respectively. Through the action of the longitudinal distribution groove 322 and the transverse distribution groove 311, the uniformity of the air flow distribution can be better guaranteed, the impurities in the gas can be better captured, and gas-liquid separation can be performed, thereby improving the practicality of the demister.
[0026] Specifically, a spacer block 303 is installed between the upper distribution plate 301 and the lower distribution plate 302, and the upper distribution plate 301 and the lower distribution plate 302 are separated by the spacer block 303. A certain distance between them can better ensure the passage of airflow, and at the same time better and more evenly distribute the airflow. The horizontal distribution groove 311 and the longitudinal distribution groove 322 are perpendicular to each other. The vertical distribution groove can prevent the airflow from rising directly, play a certain turbulent role, and thus better distribute it evenly.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
