Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer processing technology, specifically a gas scrubbing device for compound fertilizer processing. Background Technology

[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrients. Compound fertilizers have advantages such as high nutrient content, fewer by-products, and good physical properties, playing a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. Currently, the processing and production of compound fertilizers generates a large amount of harmful gases, thus requiring the use of gas scrubbing equipment for treatment.

[0003] Currently, most existing gas scrubbing devices for compound fertilizer processing directly introduce gas into the scrubbing liquid stored in the scrubbing tower. However, when the gas in the scrubbing liquid gradually accumulates and reaches its saturation limit, the excess gas will be unable to continue to undergo the expected chemical reaction with the scrubbing liquid. As a result, the scrubbing effect will be greatly reduced, and the ideal gas purification target cannot be achieved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gas scrubbing device for compound fertilizer processing. This solves the problem that most existing gas scrubbing devices for compound fertilizer processing directly introduce gas into the scrubbing liquid stored in the scrubbing tower. However, when the gas in the scrubbing liquid gradually accumulates and reaches its saturation limit, the excess gas will be unable to continue to undergo the expected chemical reaction with the scrubbing liquid. As a result, the scrubbing effect will be greatly reduced, and the ideal gas purification target cannot be achieved.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas scrubbing device for compound fertilizer processing, comprising a scrubbing pipe and a first connecting flange fixedly connected to its top and bottom ends, an inlet pipe fixedly connected to the upper side wall of the scrubbing pipe, and a nozzle connected to one end of the inlet pipe inside the scrubbing pipe, and a connecting mechanism installed at the end of the inlet pipe away from the nozzle. The connecting mechanism includes a pipe cover fixed to the upper side wall of the washing pipe, a second connecting flange fixed to the opening at the end of the pipe cover away from the washing pipe, a third connecting flange connected to the outer wall of the second connecting flange by a plurality of pairs of bolts and nuts, and a docking assembly installed on the outer side of the third connecting flange.

[0006] Preferably, the docking assembly includes a connecting pipe fixedly connected to the third connecting flange, the connecting pipe being connected to the liquid inlet pipe, and a fourth connecting flange fixedly connected to the end of the connecting pipe away from the third connecting flange.

[0007] Preferably, a sealing gasket is installed between the second connecting flange and the third connecting flange.

[0008] Preferably, the washing pipe consists of a constriction pipe, a throat pipe, and an expansion pipe from top to bottom.

[0009] Beneficial effects This utility model provides a gas scrubbing device for compound fertilizer processing, which has the following beneficial effects: The washing pipe can be installed at the exhaust position of the washing tower through the first connecting flange, and then connected to the pump body and other equipment that supply washing liquid from the outside through the fourth connecting flange. When the gas generated from compound fertilizer processing is introduced into the washing liquid in the washing tower, it will undergo preliminary washing through the washing liquid. At the same time, some gas that does not meet the washing standard will float upward and enter the washing pipe. At this time, the pump body that supplies washing liquid from the outside will draw the washing liquid into the connecting pipe, then into the inlet pipe, and finally spray it out through the nozzle to perform secondary washing treatment on the gas, thereby improving the washing effect and achieving the ideal gas purification target.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 and 2 This utility model provides a technical solution: a gas scrubbing device for compound fertilizer processing, including a scrubbing pipe 1 and a first connecting flange 2 fixedly connected to its top and bottom ends. An inlet pipe 3 is fixedly connected to the upper side wall of the scrubbing pipe 1, and one end of the inlet pipe 3 located inside the scrubbing pipe 1 is connected to a nozzle 4. A connecting mechanism is installed at the end of the inlet pipe 3 away from the nozzle 4. The connecting mechanism includes a pipe cover 5 fixedly connected to the upper side wall of the washing pipe 1. A second connecting flange 6 is fixedly connected to the opening of the pipe cover 5 away from the washing pipe 1. A third connecting flange 8 is connected to the outer wall of the second connecting flange 6 by a plurality of pairs of bolts 10 and nuts 11, and a docking assembly is installed on the outer side of the third connecting flange 8. The sealing performance at the connection between the inlet pipe 3 and the connecting pipe 7 can be improved by using the pipe cover 5.

[0015] In this embodiment, the docking assembly includes a connecting pipe 7 that is fixedly connected to the third connecting flange 8. The connecting pipe 7 is connected to the liquid inlet pipe 3, and a fourth connecting flange 9 is fixedly connected to one end of the connecting pipe 7 away from the third connecting flange 8. The washing liquid is supplied by connecting to the pump body and other equipment that supply washing liquid from the outside through the fourth connecting flange 9.

[0016] In this embodiment, a sealing gasket 12 is further provided between the second connecting flange 6 and the third connecting flange 8; The sealing gasket 12 can improve the sealing of the joint.

[0017] In this embodiment, the washing pipe 1 is further configured to consist of a constriction pipe, a throat pipe, and an expansion pipe from top to bottom; This design features a washing pipe 1 that is wide vertically and narrow in the middle. When the gas is in the middle, the flow area is smaller, allowing for more thorough contact with the washing liquid. As the gas moves upwards, the flow area increases, enabling it to be discharged quickly.

When the gas generated by compound fertilizer processing is introduced into the washing liquid in the washing tower, it will be initially washed by the washing liquid. At the same time, some gas that does not meet the washing standard will float upward and enter the washing pipe 1. At this time, the pump body that supplies washing liquid from the outside will draw the washing liquid into the connecting pipe 7, and then into the inlet pipe 3. Finally, it will be sprayed out through the nozzle 4 to perform secondary washing treatment on the gas, thereby improving the washing effect and achieving the ideal gas purification target.
