Description

Technical Field

[0001] The utility model relates to the technical field of salt-making tail gas treatment, in particular to a salt-making process dust and mist removal device with a decrystallization structure. Background Art

[0002] When treating the exhaust gas generated by the salt-making process, dust removal equipment is generally used to purify and filter the exhaust gas; in the process of exhaust gas emission, white mist will be generated after the exhaust gas comes into contact with the outside world (due to the high temperature of the exhaust gas, part of the water exists in gaseous form. When the exhaust gas is mixed with the outside world, the gaseous water in the exhaust gas will liquefy when it encounters cold and produce white mist, especially in winter). In order to avoid a large amount of white mist being discharged from the exhaust outlet and causing others to misunderstand the emission, a defogger is generally installed on the air outlet of the dust removal equipment to eliminate the generated white mist; however, the defogger is generally fixedly installed on the dust removal equipment. In the case of no white mist, the dust-removed exhaust gas will also pass through the defogger before being discharged, which will cause the defogger equipment to be working all the time, increasing losses and costs. Utility Model Content

[0003] The purpose of the utility model is to provide a salt-making process dust removal and demisting device with a decrystallization structure, so as to solve the problem that the demisting equipment proposed in the above background technology is generally fixedly installed on the dust removal equipment, and the exhaust gas after dust removal will also pass through the demisting equipment before being discharged without generating white mist, which will cause the demisting equipment to be always in operation, increase the loss and increase the cost.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example:

[0019] See also Figure 1 A salt making process dust removal and demisting device with a decrystallization structure comprises: an equipment housing 1 and a shell 2, an air inlet 3 is provided at the bottom of the equipment housing 1, a first through hole is provided at the top of the equipment housing 1, a second through hole is provided at the bottom of the shell 2, and an air outlet 4 is provided at the top of the shell 2; an ionization generating part 5 and a dust collecting part 6 are installed inside the equipment housing 1 and the shell 2, wherein the ionization generating part 5 comprises two groups of pillars (the pillars comprise two insulating rods arranged up and down, and a connecting rod is installed between the two insulating rods), and an ionization wire is installed between the two groups of connecting rods; the dust collecting part 6 comprises a bracket, and a dust collecting net is installed on the bracket; during the dust removal process, the ionization wire of the ionization generating part 5 is energized and works, and the dust collecting part 6 is grounded, so that a plasma field is generated between the ionization generating part 5 and the dust collecting part 6.

[0020] See also Figure 1 The shell 2 is movably arranged on the top of the device housing 1, and the first through hole is aligned with the second through hole; an opening 7 is opened on the side wall of the shell 2, so that the inside of the shell 2 is connected with the outside through the opening 7.

[0021] It should be noted that there are two ways to connect the shell 2 to the device housing 1, as follows:

[0022] First, see Figure 1 The shell 2 is detachably mounted on the top of the device housing 1 through a fixing member 11 (the fixing member 11 can be a bolt; the bolt is connected to the device housing 1 to fix the shell 2 on the top of the device housing 1); the connection between the fixing member 11 and the device housing 1 is disconnected, so that the connection between the shell 2 and the device housing 1 is disconnected, so that the shell 2 can be directly removed from the device housing 1, so that the first through hole and the second through hole are directly misaligned.

[0023] Second, see Figure 2 A sliding mechanism 12 (including a slide rail, a slider is slidably installed on the slide rail, and an electric telescopic rod is installed on the slide rail, and the movable end of the electric telescopic rod is connected to the slider) is provided on the top of the device housing 1, and the slider is connected to the housing 2; through the operation of the electric telescopic rod, the slider brings the housing 2 to slide on the top of the device housing 1, so as to misalign the first through hole with the second through hole.

[0024] It should also be noted that the above-mentioned two methods can make the first through hole and the second through hole staggered, so that the exhaust gas inside the equipment housing 1 does not enter the shell 2 after being discharged, so that the defogger assembly can work selectively (the defogger assembly includes the shell 2 and the ionization generating part 5, the dust collecting part 6 and other components installed in the shell 2), reduce energy consumption (the plasma field inside the shell 2 does not need to be turned on), and also reduce the number of times the defogger assembly needs to be maintained, thereby reducing costs.

[0025] Working principle: After the exhaust gas generated in the salt making process enters the interior of the equipment housing 1 through the air inlet 3, the plasma field between the ionization generating part 5 and the dust collecting part 6 inside the equipment housing 1 captures the dust particles and crystals in the exhaust gas, and the captured impurities fall on the dust collecting part 6; then the treated exhaust gas enters the inner cavity of the shell 2 through the first through hole and the second through hole; because the outside world is connected with the inside of the shell 2 through the opening 7, the exhaust gas will exchange heat with the outside world when entering the shell 2 to lower its own temperature, so that the gaseous water in the exhaust gas will liquefy to form white mist (fog condensed water); the plasma field between the ionization generating part 5 and the dust collecting part 6 inside the shell 2 will capture the generated white mist (fog condensed water will also fall on the dust collecting part 6), and then the treated exhaust gas is discharged from the air outlet 4.

[0026] It should be noted that a cleaning component for cleaning the dust collecting part 6 (such as a scraper and a driving component, the driving component is used to drive the scraper to move to scrape off the impurities attached to the surface of the dust collecting part 6) is installed inside the equipment casing 1; and a collecting trough is installed at the bottom of the dust collecting part 6 inside the shell 2 to collect the condensed water captured by the dust collecting part 6.

[0027] In this embodiment, as a further optimized solution, please refer to Figure 1 A guide member 9 is slidably provided on the shell 2, and a baffle 10 is provided on the guide member 9; when the shell 2 is moved to make the defogger assembly not work, the guide member 9 is moved to make the baffle 10 fit with the side wall of the shell 2 to cover the opening 7.

[0028] It should be noted that a shielding plate may be used to block the air outlet 4 and the second through hole.

[0029] In this embodiment, as a further optimized solution, please refer to Figure 1 A guide tube 8 is provided in the second through hole, and the guide tube 8 is inserted into the first through hole; the first through hole is connected with the second through hole through the guide tube 8, so that the exhaust gas inside the equipment housing 1 can normally enter the shell 2 for treatment, reducing the probability of exhaust gas leakage between the equipment housing 1 and the shell 2.

[0030] In this embodiment, as a further optimized solution, please refer to Figure 3The guide tube 8 includes a mounting ring 81 and a pipe 82 mounted at the bottom of the mounting ring 81. The pipe 82 is slidably mounted in the second through hole. The pipe 82 moves in the vertical direction. A sealing ring 83 (made of rubber) is sleeved on the outer wall of the pipe 82. An annular groove 84 is provided in the sealing ring 83. An air storage bag 85 (made of rubber, filled with gas) is provided at the bottom of the mounting ring 81. A channel is provided on the mounting ring 81 and the pipe 82. The air storage bag 85 is connected to the annular groove 84 through the channel. When the housing 2 needs to be moved, the pipe 83 is moved. 82 is moved up to move the pipe 82 out of the first through hole; when the shell 2 is reset to align the first through hole with the second through hole, the pipe 82 is moved down to insert the pipe 82 into the inner cavity of the first through hole. At this time, the mounting ring 81 contacts the bottom of the inner cavity of the shell 2, squeezes the air storage bag 85, and squeezes the gas inside the air storage bag 85 into the annular groove 84 through the channel, so that the sealing ring 83 is inflated and fits with the inside of the first through hole, which is used to block the gap between the pipe 82 and the first through hole, and further reduce the probability of exhaust gas leakage between the equipment housing 1 and the shell 2.

[0031] It should be noted that, in order to facilitate the up and down movement of the pipe 82, an electric telescopic rod is installed on the shell 2, and the moving end of the electric telescopic rod is connected to the pipe 82 for controlling its up and down movement.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
