Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to an environmentally friendly exhaust gas treatment device for emulsifier production. Background Technology

[0002] In the emulsifier production process, exhaust gas treatment is crucial, and spray towers, as commonly used equipment, play a key role in purifying exhaust gas. With increasingly stringent environmental regulations, the emission restrictions on harmful substances in emulsifier production exhaust gas, such as acidic gases, particulate matter, and organic pollutants, are becoming more stringent. At the same time, the continuous expansion of emulsifier production scale has led to a significant increase in the amount of exhaust gas that needs to be treated, placing higher demands on the efficiency, stability, and environmental friendliness of exhaust gas treatment equipment.

[0003] Currently, existing spray towers have significant shortcomings in terms of nozzle replacement. The connection between nozzles and pipes in traditional spray towers is complex and mostly fixed. Once a nozzle malfunctions, such as blockage or wear, the entire spray system must be shut down for repair or replacement, and operators may even need to enter the tower to work. This not only leads to production interruption and huge economic losses, but also increases the safety risks for operators. In view of this, we propose an environmentally friendly tail gas treatment device for emulsifier production. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5 As shown, an environmentally friendly tail gas treatment device for emulsifier production includes a tower body 1, a main spray pipe 2, several transition connecting pipes 3, several spray branch pipes 4, and several glass observation windows 5. The glass observation windows 5 are fixedly installed on the outer walls of the tower body 1. Through the glass observation windows 5, the spraying situation inside the tower body 1 can be directly observed. The main spray pipe 2 and the transition connecting pipes 3 are both fixedly installed on the outer wall of the tower body 1. The several spray branch pipes 4 are connected to the main spray pipe 2 through the several transition connecting pipes 3. The spray branch pipes 4 pass horizontally through the outer wall of the tower body 1.

[0025] refer to Figure 2Several first insertion guide sleeves 11 are fixedly installed on the outer wall of the tower body 1. Several spray branch pipes 4 slide through the several first insertion guide sleeves 11 in a sealed manner. The end of the transition connecting pipe 3 is vertically connected to a second insertion guide sleeve 31. Several spray branch pipes 4 slide through the several second insertion guide sleeves 31 in a sealed manner. Each spray branch pipe 4 has a connecting hole 45 on one side of its head end for connecting to the inner cavity of the transition connecting pipe 3. A nozzle 42 can be detachably installed at the end of each spray branch pipe 4. The maximum outer diameter of the nozzle 42 is smaller than the inner diameter of the first insertion guide sleeve 11. The length of the nozzle 42 is less than the inner length of the first insertion guide sleeve 11. The other end of the nozzle 42 is detachably equipped with an inner plug 43. The inner plug 43 and the spray branch pipe 4 are coaxially arranged, and the outer diameter of the inner plug 43 and the spray branch pipe 4 are the same. The inner plug 43 is mainly used to block the inner hole of the first insertion guide sleeve 11 after the nozzle 42 is pulled out. Combined with the fact that the length of the nozzle 42 is less than the inner length of the first insertion guide sleeve 11, the inner hole of the first insertion guide sleeve 11 can always be blocked by the spray branch pipe 4 or the inner plug 43 when the nozzle 42 passes through the inner hole of the first insertion guide sleeve 11.

[0026] refer to Figure 4 The second insertion guide sleeve 31 is equipped with a sealing and pressurizing mechanism 6 to increase the sealing and stability between the second insertion guide sleeve 31 and the spray branch pipe 4. The sealing and pressurizing mechanism 6 consists of a handwheel 61, a screw 62, a cylindrical protective shell 63, a connecting plate 64, a bellows airbag 65, two annular airbags 66, and two annular connecting sleeves 67. The two annular connecting sleeves 67 are coaxially fixedly installed at both ends of the second insertion guide sleeve 31, and the two annular airbags 66 are coaxially fitted into the two annular connecting sleeves 67. The protective shell 63 is fixedly installed on one side of the second insertion guide sleeve 31. The inner cavities of the corrugated tube airbag 65 and the two annular airbags 66 are interconnected through a conduit. The lower end face of the corrugated tube airbag 65 is fixedly connected to the inner bottom surface of the cylindrical protective shell 63. The connecting plate 64 is fixedly connected to the upper end face of the corrugated tube airbag 65. The connecting plate 64 is telescopically installed inside the cylindrical protective shell 63. The end of the screw 62 is rotatably connected to the connecting plate 64. The beginning end of the screw 62 is fixedly connected to the handwheel 61. The screw 62 and the cylindrical protective shell 63 are threadedly connected.

[0027] refer to Figure 3Annular sealing grooves 44 are provided on both sides of the connecting hole 45 in the spray branch pipe 4. The positions of the two annular sealing grooves 44 on the spray branch pipe 4 correspond to the positions of the two annular airbags 66 in the sealing and pressurizing mechanism 6. That is, when the handwheel 61 is turned, the bellows airbag 65 can be extended and retracted through the screw 62 and the connecting plate 64. When the gas or liquid in the bellows airbag 65 is squeezed into the two annular airbags 66, the inner ring of the annular airbag 66 expands and presses against the two annular sealing grooves 44 on the spray branch pipe 4, which increases the sealing and stability between the second insertion and removal guide sleeve 31 and the spray branch pipe 4. A handle 41 is fixedly installed at the head end of the spray branch pipe 4. The handle 41 is mainly used to facilitate the insertion and removal of the spray branch pipe 4. The outer end face of the handle 41 is provided with an indicator mark 411 for indicating the direction of the nozzle 42 and the connecting hole 45. The indicator mark 411 makes it easy for the user to judge whether the installation direction of the spray branch pipe 4 is correct.

[0028] It should be added that the sealing and pressurizing mechanism 6 can also be set on the outer wall of the tower body 1 to increase the sealing and stability between the tower body 1 and the spray branch pipe 4. That is, one side of the annular airbag 66 in the sealing and pressurizing mechanism 6 is attached to the outer wall of the tower body 1, and the inner ring of the annular airbag 66 is coaxially set on the outer ring of the spray branch pipe 4.

[0029] refer to Figure 5 Below the nozzle 42, there is a conical nozzle 421. Inside the conical nozzle 421, there is a coaxially arranged round rod 424. The diameter of the round rod 424 is smaller than the minimum inner diameter of the conical nozzle 421. The first end of the round rod 424 is threaded to the inner wall of the nozzle 42. The end of the round rod 424 is fixedly installed with a spherical guide block 422 with a spherical surface protruding upward. The outer ring of the spherical guide block 422 is provided with several water-passing slots 423. When the liquid sprayed vertically downward in the conical nozzle 421 directly sprays onto the spherical guide block 422 with a spherical surface protruding upward, the liquid is dispersed. Then, the liquid sprayed from the conical nozzle 421 can be further dispersed by the several water-passing slots 423 on the outer ring of the spherical guide block 422.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
