Description

Technical Field

[0001] The invention relates to the technical field of air circulation, in particular to an air circulation component of a cooling device for fertilizer production. Background Art

[0002] The fertilizer production cooling device is a device used to cool down the high-temperature exhaust gas during fertilizer production. It is an essential auxiliary production equipment in the fertilizer production process. It can cool down the high-temperature exhaust gas before subsequent deodorization and harm removal operations. The air circulation component is a purification device attached to the cooling device. It can treat the cooled exhaust gas harmlessly and then discharge it into the circulating atmosphere.

[0003] The air circulation components must have a filtering structure and a spray cooling structure. The filtering structure is used to harmlessly treat the exhaust gas, while the spray cooling structure is used to reduce the increase in gas temperature caused by the waste heat of the cooling equipment. The two are interdependent.

[0004] The spray structure and the filter structure of the existing air circulation components cooperate poorly with each other and can be said to exist independently of each other. Moreover, the spray structure and the filter structure are mostly fixed when they are set. Although they have their own functions, the uncertainty of gas flow during use leads to blind spots in cooling and filtering when the spray structure and the filter structure cooperate with each other, resulting in poor use effect, which easily leads to a certain amount of harmful components in the exhaust gas. In addition, the fixed spray structure and the filter structure are inconvenient to replace and repair in the later stage. Therefore, an air circulation component of a cooling device for fertilizer production is proposed to solve the above-mentioned problems. Summary of the invention

Although they have their own functions, during use, due to the uncertainty of gas flow, the spray structure and the filter structure are prone to have blind spots in cooling and filtration when they cooperate with each other, resulting in poor use effect, and easily leading to a certain amount of harmful components in the discharged gas, and the fixed spray structure and filter structure are relatively inconvenient in later replacement and maintenance.

[0060] Working principle:

[0061] The first step: start the liquid injection machine 801, the liquid injection machine 801 sucks the external water into the liquid injection machine 801, and mixes it with the deodorizing particles to form a mixed liquid, and then introduces the mixed liquid into the air intake shell 2 through the inlet pipe 804, fills the air intake shell 2 with the mixed liquid containing the deodorizing particles, and then introduces the exhaust gas into the air intake shell 2 through the air intake pipe 901, and at the same time, the gas entering the air intake shell 2 is decelerated by the deceleration plate 903 to increase the residence time in the liquid in the air intake shell 2, and the gas is initially cooled by the mixed liquid. At the same time, the odor in the gas is adsorbed by the deodorizing particles, and the soluble substances in the gas are dissolved in the mixed liquid by the liquid. When the gas separates from the mixed liquid and rises, it first enters the second filter shell 702 through the interception net 706, and the water-insoluble particles in the gas are adsorbed by the adsorption particles 705 in the second filter shell 702. The adsorbed gas continues to rise through the discharge hole 707 to the bottom of the atomizing nozzle 505;

[0062] Step 2: When the gas enters, the motor 402 is started, and the motor 402 drives the first gear 404 to rotate, and the second gear 405 is driven to rotate through the first gear 404, so that the water inlet pipe 501 is driven to rotate in the positioning ring 502 through the second gear 405. When the water inlet pipe 501 rotates, it also rotates inside the protective pipe 503. The annular pipe 504 is driven to rotate through the rotation of the water inlet pipe 501, thereby driving the atomizing nozzle 505 to rotate. When water is injected, the external water source is introduced through the water guide pipe 1002, and the external water source is directly introduced into the water inlet pipe 501 through the guide pipe 1003. When water is introduced, the sealing shell 1001 drives the guide pipe 1003 to rotate through the rotation of the water inlet pipe 501. Under the condition of keeping the water source flowing, the water inlet pipe 501 also has the function of rotating;

[0063] Step 3: After the gas rises to the bottom of the atomizing nozzle 505, the gravity of the water is increased by atomizing water, making the gas humid. The humid air further adsorbs the water-insoluble particles and cools the gas again. The gas then continues to rise. When passing through the first filter shell 701, the adsorption particles 705 with smaller particle diameters inside adsorb and deodorize the gas for the last time, and then the gas is discharged to the next process by the exhaust mechanism 6.
