[0035] Next, in combination with the specific embodiments of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] As Figure 1-6 shown, an atmospheric condenser with a rotary nozzle of the present utility model includes a condensation tank 1, an exhaust pipe 2, a cooling pipe 3 and a sprinkler head 4.

[0037] Among them, the condensation tank 1 is used to provide a treatment environment for the condensation of steam in the grease refining and deodorization gas.

[0038] The exhaust pipe 2 is used to communicate with a vacuum pump to extract the gas with steam removed to the outside of the condensation tank 1. The exhaust pipe 2 is hermetically fixed on the condensation tank 1 and communicates with it.

[0039] The cooling pipe 3 is used to convey high-pressure cooling liquid into the condensation tank 1. The cooling pipe 3 penetrates and is fixed on the condensation tank 1.

[0040] The sprinkler head 4 is used to atomize the high-pressure cooling liquid in the cooling pipe 3 and spray it into the gas in the condensation tank 1, as Figure 2As shown in the figure, the spray head 4 is fixedly arranged at one end of the cooling pipe 3 located inside the condensation tank 1; a diversion cavity 401, a rotating cavity 402 and a spray port 403 which are connected in sequence are arranged inside the spray head 4. The diversion cavity 401 is located at one end of the spray head 4 close to the cooling pipe 3 and is communicated with the cooling pipe 3. The diversion cavity 401 has a spiral structure. When high-pressure coolant flows into the spray head 4 through the cooling pipe 3, it first rotates under the guidance of the diversion cavity 401, then forms a rotating forward water flow in the rotating cavity 402, and finally forms mist droplets through the spray port 403 to be evenly sprayed in the gas. This atomization process is the prior art; during this period, by rotating the high-pressure coolant through the diversion cavity 401, not only can the flow rate of the coolant be increased and its atomization effect be improved, but also the phenomenon of blockage inside the spray head 4 can be avoided.

[0041] In order to improve the rotation efficiency of the coolant, it is preferably that the side of the diversion cavity 401 far from the cooling pipe 3 is planar, intersects with the central axis of the spray head 4 and is not perpendicular, that is, the water-facing surface of the diversion cavity 401 is planar and is inclined with respect to the central axis of the spray head 4, so as to guide the high-pressure coolant flow in the shortest stroke and improve its rotation efficiency.

[0042] It is also possible to make the inner diameter of the diversion cavity 401 gradually decrease and then gradually increase from the end close to the cooling pipe 3 to the end far from the cooling pipe 3, so as to make the flow rate of the coolant unstable, thereby improving the anti-blocking effect of the spray head 4.

[0043] When the water-facing surface of the diversion cavity 401 is horizontal, its wear condition will be increased. Therefore, the spray head 4 includes a rotating cup 41 and a diversion core 42. Among them, the rotating cavity 402 and the spray port 403 are arranged inside the rotating cup 41; the diversion core 42 is detachably fixed inside the rotating cup 41 and encloses with it to form two diversion cavities 401, so that the diversion core 42 can be replaced or maintained regularly to ensure the performance of the spray head 4; specifically, as Figure 1 and Figure 3 As shown in the figure, an installation groove 405 is opened at one end of the rotating cup 41 close to the cooling pipe 3. The diversion core 42 is arranged in the installation groove 405 and abuts against the side of the installation groove 405 far from the cooling pipe 3. This not only facilitates the disassembly and assembly operation of the diversion core 42 and the rotating cup 41, but also can improve its fixing firmness by using the abutment of the installation groove 405 on the diversion core 42.

[0044] As Figure 1 、 Figures 4-6As shown in the figure, the flow guide core 42 includes a spacer plate 421, two flow guide plates 422 and an extension plate 423. One end of the flow guide plate 422 close to the cooling pipe 3 is fixedly arranged on the spacer plate 421, and both of them are detachably and sealingly connected to the rotary cup 41, thus forming a flow guide cavity 401; the spacer plate 421 is parallel to the center line of the spray head 4, and the flow guide plate 422 intersects with the center line of the spray head 4 and is not perpendicular; the two flow guide plates 422 are respectively arranged on both sides of the spacer plate 421 and are centrosymmetric about the center point of the spacer plate 421, thus forming two flow guide cavities 401.

[0045] In order to improve the guiding efficiency of the flow guide cavity 401 for the high-pressure coolant, an expansion hole 404 can also be opened on the flow guide plate 422, and the side of the expansion hole 404 far from the cooling pipe 3 intersects with the center line of the spray head 4 and is not perpendicular.

[0046] One extension plate 423 is fixedly arranged at one end of each flow guide plate 422 far from the spacer plate 421. The end of the extension plate 423 far from the flow guide plate 422 and the end of the flow guide plate 422 connected thereto close to the spacer plate 421 are respectively flush with both sides of the spacer plate 421, that is, the extension plate 423 on the flow guide plate 422 extends to the other side of the spacer plate 421, thus lengthening the spiral path of the high-pressure coolant and improving the effect of the high-pressure coolant rotating in a spiral manner.

[0047] As Figure 3 shown, a fixing groove 406 is opened at one end of the outer side of the spray head 4 close to the cooling pipe 3. Threads are opened in the fixing groove 406 and it is connected to the cooling pipe 3 by thread fit. After the upper end of the spray head 4 is screwed into the interior of the cooling pipe 3, the lower side in the fixing groove 406 can abut against the cooling pipe 3, thus improving its sealing performance; and in order to improve this sealing performance, a sealing groove 407 can also be opened on the side of the fixing groove 406 far from the cooling pipe 3, and a sealing ring is clamped in the sealing groove 407.

[0048] The using method of an atmospheric condenser with a rotary nozzle of the present utility model is as follows:

[0049] Add the grease refining and deodorizing gas into the condensation tank 1, connect the exhaust pipe 2 to the vacuum pump, and connect the cooling pipe 3 to the coolant supply device. First, use the cooling pipe 3 to input high-pressure coolant into the condensation tank 1. The high-pressure coolant forms a high-speed flowing rotating water flow in the rotating cavity 402 under the guidance of the flow guide cavity 401 and is atomized and sprayed out from the spray orifice 403, thus evenly spraying the gas in the condensation tank 1, causing the steam in this gas to liquefy. After the steam liquefaction is completed, start the vacuum pump to extract the gas in the condensation tank 1; during this period, rotating the atomizing spray head 4 of the coolant can achieve a better spraying effect, thus reducing the number of spray heads 4 put into use and optimizing the structure in the condensation tank 1.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
