Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a desulfurization humidification atomization device. Background Art

[0002] Desulfurization and humidification uses an external humidifier. The working principle of the humidifier is that after the material enters the humidifier, the blades are driven by the reduction motor to rotate for stirring, and the water mist sprayed from the top of the humidifier is fully mixed with the material, and then recycled into the flue gas to achieve the purpose of continuous desulfurization.

[0003] The material flows into the desulfurization tower through the negative pressure of the front discharge port in the humidifier. Due to the large gap between the stirring blades, the material in the gap cannot be stirred and forms a "dam" shape, which blocks the normal movement of the material, causing the humidifier to flow poorly or block the humidifier, seriously affecting the desulfurization effect. In addition, a water mist spray device for material humidification will be installed on the top of the humidifier. Since the water spray end of the water mist spray device is exposed to dusty materials for a long time, it is easy to cause blockage inside the water mist spray device. Utility Model Content

[0004] In view of the above-mentioned technical problems existing in the prior art, a desulfurization humidification atomization device is provided, which effectively solves the problem that due to the large gap between the stirring blades, the materials in the gaps cannot be stirred and form a "dam" shape, thereby blocking the normal movement of the materials; with the use of a shielding member, not only can the water mist spray device be shielded when not in use to prevent internal blockage of the water mist spray device, but the shielding member can also be moved down and used in conjunction with the water mist spray device to achieve self-cleaning of the water spray end of the water mist spray device.

[0005] The purpose and effect of the utility model are achieved by the following specific technical means:

[0006] A desulfurization humidification atomization device comprises a frame and a body mounted on the frame, a stirring device is installed in the body, and a water mist spraying device is installed on the top of the body, and a water spraying end of the water mist spraying device passes through the top of the body;

[0007] The stirring device comprises a rotating shaft and a plurality of rows of stirring blades uniformly fixed on the rotating shaft, at least one row of stirring blades having an angle steel in contact with the inner wall of the machine body fixed at the outer end, and the angle steel scrapes the material attached to the inner wall of the machine body when rotating;

[0008] A shielding member for shielding the water spraying end of the water mist spraying device is installed on the top of the inner wall of the machine body, and the shielding member includes a longitudinal movable unit, a slide rail and a baffle. Two longitudinal movable units are provided and are both installed on the top of the machine body, and the lower ends of the longitudinal movable units pass through the top of the machine body. The slide rail is fixed at the lower ends of the two longitudinal movable units. The baffle is slidably connected to the slide rail through a groove, and the baffle contacts the top of the inner wall of the machine body and shields the water spraying end of the water mist spraying device.

[0009] The longitudinal movable unit comprises a lifting rod and a mounting tube, wherein the mounting tube is fixed to the top of the machine body, the lifting rod is slidably connected in the mounting tube, and a damper is arranged between the lifting rod and the mounting tube.

[0010] The top of the inner wall of the machine body and the top of the baffle are both smooth surfaces.

[0011] A reduction motor is fixed at one end of the machine body, and an output end of the reduction motor passes through the frame and the machine body and is fixedly connected to one end of the rotating shaft.

[0012] The water mist spray device includes a water pipe rack, a water mist nozzle and a high-pressure air pipe. The water pipe rack is fixed to the top of the machine body. The water mist nozzle is provided with a plurality of water mist nozzles and all are connected to the water pipe rack. The water spraying ends of the water mist nozzles all pass through the top of the machine body. The baffle is located below the plurality of water mist nozzles. The high-pressure air pipe is connected to the water pipe rack.

[0013] A pressure reducing valve is installed on the high-pressure air pipe.

[0014] A through hole matching the baffle is opened on one side of the machine body, and a sealing block is embedded in the through hole.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] When the stirring device in this desulfurization humidification atomization device rotates, it will drive the angle steel to rotate together, and the angle steel will scrape the materials attached to the inner wall of the machine body. Therefore, when the machine body is running, all the materials inside can be stirred, effectively solving the problem that there is a large gap between the stirring pieces, and the materials in the gaps cannot be stirred, forming a "dam" shape, blocking the normal movement of the materials, reducing the raw material consumption and the calcium hydroxide content of the desulfurization ash, and fully improving the desulfurization effect;

[0017] If the water mist spray device is not in use, the baffle in the shielding member can shield the water spray end of the water mist spray device to prevent the powdered material from splashing onto the water spray end of the mist spray device when being stirred, thereby causing blockage inside the mist spray device;

[0018] By using the longitudinal movable unit to drive the baffle and the slide rail to move downward, a gap is created between the baffle and the water spraying end of the mist spraying device. The water mist spraying device is then started to spray water mist into the space between it and the baffle. The water mist will diffuse or splash onto the surface of the water spraying end of the water mist spraying device, thereby enabling the water mist spraying device to automatically clean its water spraying end.

DETAILED DESCRIPTION

[0029] See also Figure 1-9 , the embodiments of the utility model are further described;

[0030] A desulfurization humidification atomization device comprises a frame 1 and a body 2 mounted on the frame 1, a stirring device is installed in the body 2, and a water mist spraying device is installed on the top of the body 2, and a water spraying end of the water mist spraying device passes through the top of the body 2;

[0031] The stirring device includes a rotating shaft 4 and a plurality of rows of stirring blades 5 uniformly fixed on the rotating shaft 4, at least one row of stirring blades 5 is fixed with an angle steel 6 in contact with the inner wall of the machine body 2 at the outer end, and the angle steel 6 scrapes the material attached to the inner wall of the machine body 2 when rotating;

[0032] A reduction motor 3 is fixed at one end of the body 2, and the output end of the reduction motor 3 passes through the frame 1 and the body 2 and is fixedly connected to one end of the rotating shaft 4;

[0033] Specifically, when the machine body 2 is working, the reduction motor 3 will be connected to an external power supply, the reduction motor 3 will drive the rotating shaft 4 to rotate, and the rotating shaft 4 will drive several rows of stirring blades 5 to stir the materials in the machine body 2. Since the angle steel 6 connects the outer ends of a row of stirring blades 5, there is no gap between the outer ends of this row of stirring blades 5. When the stirring device rotates, it will drive the angle steel 6 to rotate together, and the angle steel 6 will scrape the materials attached to the inner wall of the machine body 2. Therefore, when the machine body 2 is running, all the materials inside can be stirred, which effectively solves the problem of large gaps between the stirring blades 5, the materials in the gaps cannot be stirred and form a "dam" shape, blocking the normal movement of the materials, reducing raw material consumption and the calcium hydroxide content of desulfurization ash, and fully improving the desulfurization effect.

[0034] A shielding member for shielding the water spraying end of the water mist spraying device is installed on the top of the inner wall of the body 2, and the shielding member includes a longitudinal movable unit, a slide rail 14 and a baffle 13. Two longitudinal movable units are provided and are both installed on the top of the body 2, and the lower ends of the longitudinal movable units pass through the top of the body 2. The slide rail 14 is fixed at the lower ends of the two longitudinal movable units. The baffle 13 is slidably connected to the slide rail 14 through a groove, and the baffle 13 contacts the top of the inner wall of the body 2 and shields the water spraying end of the water mist spraying device;

[0035] A through hole 16 matching the baffle 13 is formed on one side of the body 2, and a sealing block 15 is embedded in the through hole 16;

[0036] Specifically, if the water mist spray device is not in use, Figure 1 , 3 As shown in FIG. 4 , the baffle 13 blocks the water spray end of the water mist spray device to prevent the powdered material from splashing to the water spray end of the mist spray device when being stirred and causing blockage inside the mist spray device. The sealing block 15 blocks the through hole 16 to prevent the material in the body 2 from splashing out.

[0037] If the water mist spray device is used, Figure 1 , 4and 5, the sealing block 15 is pulled out from the through hole 16, and then the baffle 13 is slid toward the through hole 16 so that the baffle 13 is staggered with the water spraying end of the mist spraying device, and the water mist spraying device can be used to perform water mist spraying humidification treatment on the material.

[0038] If a small amount of dust adheres to the water spray end of the mist spray device after it has been used for a period of time, it needs to be cleaned. Figure 6 and 7 , by using the longitudinal movable unit to drive the baffle 13 and the slide rail 14 to move downward, so that there is a gap between the baffle 13 and the water spray end of the mist spray device, and then the water mist spray device is started to spray water mist in the space between it and the baffle 13, and the water mist will diffuse or splash onto the surface of the water spray end of the water mist spray device. After spraying for a period of time, the water mist on the surface of the water spray end will turn into water droplets, so the dust attached to the surface of the water spray end will fall on the baffle 13 with the water droplets, and the water on the baffle 13 will slowly flow into the body 2. The shielding member is used in conjunction with the water mist spray device to realize that the water mist spray device automatically cleans its water spray end.

[0039] The longitudinal movable unit includes a lifting rod 11 and a mounting tube 12. The mounting tube 12 is fixed to the top of the machine body 2. The lifting rod 11 is slidably connected in the mounting tube 12, and a damper is provided between the lifting rod 11 and the mounting tube 12.

[0040] Specifically, when the longitudinal movable unit is in use, the longitudinally moving lifting rod 11 drives the baffle 13 and the slide rail 14 to move up or down. The upward movement of the baffle 13 can make the baffle 13 fit the top of the inner wall of the body 2, so that the water spray end of the water mist spray device is blocked by the baffle 13 to prevent materials from splashing onto the water spray end; the downward movement of the baffle 13 can make the baffle 13 away from the top of the inner wall of the body 2, so as to self-clean the water spray end of the water mist spray device later. The purpose of setting the damping between the lifting rod 11 and the mounting tube 12 is to increase the friction resistance between the lifting rod 11 and the mounting tube 12, to prevent the lifting rod 11 from sliding down by itself due to the influence of its own gravity and the baffle 13 and the slide rail 14, and to enhance the stability of the lifting rod 11. It should be noted that, for greater convenience, the longitudinal movable unit can adopt an electric lifting rod, and the slide rail 14 can adopt an electric slide rail.

[0041] The top of the inner wall of the body 2 and the top of the baffle 13 are both smooth surfaces;

[0042] Specifically, the setting that the top of the inner wall of the body 2 and the top of the baffle 13 are both smooth surfaces is conducive to the mutual fit between the top of the baffle 13 and the top of the inner wall of the body 2, which can greatly reduce the gap between the body 2 and the baffle 13, thereby preventing dust from splashing to the top of the baffle 13 when the water mist spray device is not in use; on the other hand, when the water mist spray device cleans its water spray end, due to the small resistance on the top of the baffle 13, the water falling on the baffle 13 can flow out quickly.

[0043] The water mist spray device includes a water pipe rack 7, a water mist nozzle 8 and a high-pressure air pipe 9. The water pipe rack 7 is fixed to the top of the machine body 2. The water mist nozzle 8 is provided with a plurality of water mist nozzles and all are connected to the water pipe rack 7. The water spray ends of the water mist nozzles 8 all pass through the top of the machine body 2. The baffle 13 is located below the plurality of water mist nozzles 8. The high-pressure air pipe 9 is connected to the water pipe rack 7.

[0044] Specifically, the water pipe rack 7 can be connected to a tap water pipe, and the high-pressure gas pipe 9 is connected to an air source. When the tap water pipe is turned on, the water inside it flows to the water pipe rack 7. When the air source is turned on, the high-pressure gas enters the high-pressure gas pipe 9, and then enters the water pipe rack 7 containing tap water, thereby forming a spray, which is finally sprayed out through the water mist nozzle 8. The formation and spraying of water mist are based on existing technologies.

[0045] A pressure reducing valve 10 is installed on the high pressure gas pipe 9;

[0046] Specifically, the setting of the pressure reducing valve 10 can adjust the air pressure in the high-pressure air pipe 9, ensuring the stability of the air source and saving the use of compressed air. The water flow in the water pipe rack 7 is also more stable, making the tap water atomization effect better.
