For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The present invention relates to a purification device, which comprises a first processing unit, a second processing unit, a third processing unit, a fourth processing unit and a fifth processing unit, and the oil smoke passes through the first processing unit, the second processing unit, the third processing unit, the fourth processing unit and the fifth processing unit in sequence. A water pool is arranged at the bottom of the purification device, and the water in the purification process flows into the water pool.

[0041] The purification equipment is provided with an upper cabin and a lower cabin. The upper cabin is arranged above the lower cabin, and the dry and wet separation is carried out to effectively separate the moisture in the oil fume gas. The first processing unit, the second processing unit and the third processing unit are arranged in the lower cabin, and the fourth processing unit and the fifth processing unit are arranged in the upper cabin. The purification equipment is provided with an equipment cabin, which is arranged at the bottom of the purification equipment. The equipment cabin is provided with a refrigeration system, a water supply system and an air compression system, and the air compression system includes an air compressor 407.

[0042] The first processing unit includes an air inlet, a spray assembly and a plurality of flow stabilizers 103. The oil smoke enters the first processing unit from the air inlet, and the side of the flow stabilizer 103 facing the air inlet is the front side. The front side of the flow stabilizer 103 diverts the oil smoke to the left and right sides. The rear area of ​​the flow stabilizer 103 constitutes an eddy zone 102. The diverted oil smoke airflow forms a swirling vortex in the eddy zone 102. The inner cavity of the first processing unit is regarded as an aerosol mixing chamber 101. The spray assembly is used to spray water to the eddy zone 102. The spray assembly includes a plurality of nozzles 104. The air compression system enables the spray assembly to spray water to form a fine water mist. The diameter of the water particles in the fine water mist is less than 1000 μm. The fine water mist is fully mixed with the oil smoke in the eddy zone 102 to form an aerosol with high humidity, which is conducive to fully adsorbing the oil smoke in the subsequent processing process, and is convenient for fully capturing non-methane particles in the oil smoke, and the oil smoke purification effect is better.

[0043] The flow stabilizer 103 is arranged upright, and the flow stabilizer 103 includes two flow guide wings, one of which guide wings guides the oil smoke to the left, and the other guide wing guides the oil smoke to the right. In some examples, the two flow guide wings form a V-shaped structure, for example, the flow stabilizer 103 is arranged as a V-shaped channel steel, the tip of the V-shaped structure faces the air inlet, and the vortex zone 102 is located in the V-shaped area of ​​the V-shaped structure. In some examples, the flow guide wings are arc-shaped, specifically, the flow guide wings are bent toward the rear side, for example, the flow stabilizer 103 is an arc-shaped structure, and the fan-shaped area behind the flow stabilizer 103 is the vortex zone 102, for example, the flow stabilizer 103 is arranged as a column, and the cross-section of the column is fan-shaped or semicircular.

[0044] The flow stabilizers 103 are distributed in an array. To promote oil smoke diversion, the flow stabilizers 103 are staggered. Specifically, two adjacent rows of flow stabilizers 103 are staggered to form more eddy flow areas 102 to fully mix the oil smoke and fine water mist.

[0045] The second processing unit includes a plurality of mesh chains 201 and a plurality of second connecting ropes 202, and each mesh chain 201 is arranged in sequence so that the oil smoke can pass through each mesh chain 201 in sequence. The second processing unit also includes a main bracket, and each mesh chain 201 is arranged side by side in the main bracket in sequence. The mesh chain 201 is made of stainless steel, and the mesh chain 201 is used to absorb oil droplets in the oil smoke, and the oil and water are separated through the layer-by-layer filtration of each mesh chain 201. The aerosol adheres to the mesh chain 201, and the temperature is reduced to form condensation, which falls off and flows into the water pool.

[0046] The second connecting rope 202 passes through each mesh chain 201 in sequence, and a second tail wing 203 is provided at the tail end of the second connecting rope 202. When the oil smoke passes through the mesh chain 201, the wind kinetic energy of the oil smoke will cause the mesh chain 201 to swing, and at the same time, the second tail wing 203 will swing. The second tail wing 203 drives the second connecting rope 202 to swing, and the second connecting rope 202 drives each mesh chain 201 to swing, so that the swing of each mesh chain 201 is strengthened. Further, the second tail wing 203 is in the form of a sheet, and under the action of wind kinetic energy, the sheet structure is easier to swing. The swinging mesh chain 201 causes the adsorbed particles to fall off, thereby realizing the self-cleaning of the mesh chain 201. The adjacent mesh chains 201 collide with each other due to the swinging, which can strengthen the swing of the mesh chain 201, thereby strengthening the self-cleaning function of the mesh chain 201. In addition, since the mesh chain 201 is set to be multi-layered, the filtering path is correspondingly extended, and the mesh chain 201 adsorbs layer by layer, which can prevent the oil smoke airflow from entraining the falling particles.

[0047] The main support includes two longitudinal beams 204, and a plurality of transverse beams 205 for mounting each network chain 201 are arranged between the two longitudinal beams 204. The network chain 201 is mounted on the transverse beam 205 through a plurality of collars 206, and each collar 206 is sleeved on the transverse beam 205. Specifically, the upper part of the network chain 201 is mounted on the transverse beam 205 through a plurality of collars 206, and the longitudinal beam 204 is provided with a mounting hole for mounting the end of the transverse beam 205.

[0048] The main support includes a plurality of vertical beams 207, which are vertically arranged for mounting the longitudinal beams 204. The vertical beams 207, the longitudinal beams 204 and the transverse beams 205 constitute the framework of the main support. Further, the longitudinal beams 204 are angle steels, and the vertical beams 207 are angle steels.

[0049] The third processing unit includes a plurality of third filter plates 301, each of which is arranged in sequence, so that the oil smoke passes through each of the third filter plates 301 in sequence, and the fine aerosol further adheres to the third filter plate 301 to form liquid water flowing down. The third filter plate 301 is provided with a plurality of third filter holes 302, and the inner wall of the third filter hole 302 can absorb the particulate matter of the oil smoke. Specifically, each third filter hole 302 is distributed in an array on the third filter plate 301.

[0050] A third connecting rope 303 is provided in the third filter hole 302, and a third tail wing 304 is provided at the tail of the third connecting rope 303. The wind kinetic energy carried by the oil smoke will cause the third tail wing 304 to swing, and the third tail wing 304 drives the third connecting rope 303 to swing in the third filter hole 302. The third connecting rope 303 collides and falls off the attachments in the third filter hole 302, so that the third processing unit achieves a self-cleaning effect. Furthermore, the third tail wing 304 is in the form of a sheet, and under the action of the wind kinetic energy, the sheet structure is easier to swing. In some examples, the third connecting rope 303 is designed as a bendable and swingable connecting rope; in some examples, the third connecting rope 303 is designed as a chain, and the collision between the chain and the inner wall of the third filter hole 302 makes it easier to cause the attachments to fall off.

[0051] In the third filter plate 301, the heads of the third connecting ropes 303 in two adjacent third filter holes 302 are connected, and the two swinging third tail wings 304 drive one third connecting rope 303 to swing, and the swing amplitude of the third connecting rope 303 is larger.

[0052] The passage path in the third filter hole 302 is arc-shaped, thereby extending the path of the oil smoke in the third filter hole 302 and enhancing the adsorption effect of the third filter hole 302 on the oil smoke particles. The length of the third connecting rope 303 in the arc-shaped third filter hole 302 is correspondingly extended, and accordingly, the swing of the third connecting rope 303 in the third filter hole 302 is enhanced, and the self-cleaning effect is enhanced.

[0053] In the third treatment unit, the oil fume passes through each third filter plate 301 in sequence. In addition, the flow path of the oil fume is formed between two adjacent third filter plates 301, and the flow directions of the oil fume in two adjacent sections of the flow path are opposite. Specifically, the left end of the two adjacent third filter plates 301 that form the flow path is the entrance of the flow path, and the left end of the second third filter plate 301 is the outlet of the flow path. When the oil fume flows through the third filter plate 301 in the forward direction, due to the unbalanced pressure difference, the excess oil fume flows along the flow path to the next layer of the third filter plate 301, which reduces the resistance of the filtration of the third filter plate 301 and effectively improves the purification effect of the third treatment unit. The flow trajectory of the oil fume in the third treatment unit is in a zigzag shape, thereby increasing the contact time between the oil fume and the third filter plate 301 and enhancing the adsorption effect of the third filter plate 301 on the oil fume.

[0054] The third processing unit includes a plurality of third brackets for mounting the third filter plate 301, the third bracket includes a third upper bracket 305 and a third lower bracket 306, the third upper bracket 305 is provided with a third mounting groove for mounting the third filter plate 301, and the third lower bracket 306 is provided with a third mounting groove for mounting the third filter plate 301. Specifically, the upper side of the third filter plate 301 is mounted in the third mounting groove of the third upper bracket 305, and the lower side of the third filter plate 301 is mounted in the third mounting groove of the third lower bracket 306.

[0055] The fourth processing unit includes a plurality of fourth filter plates 401, each of which is arranged in sequence so that the oil smoke passes through each of the fourth filter plates 401 in sequence. The fourth filter plate 401 is provided with a refrigeration pipe 405, which is arranged on the side of the fourth filter plate 401. The odor of the oil smoke is reduced by refrigeration, and the gaseous substances in the oil smoke are liquefied for more effective adsorption and enhanced purification effect. Finer aerosols are condensed on the fourth filter plate 401 through the refrigeration pipe 405 to remove moisture, thereby achieving oil smoke purification with a relative humidity below 30%, and also reducing the odor concentration.

[0056] The fourth filter plate 401 is provided with a plurality of fourth filter holes 402 , and the inner walls of the fourth filter holes 402 can adsorb particulate matter of oil smoke. Specifically, the fourth filter holes 402 are distributed in an array on the fourth filter plate 401 .

[0057] A fourth connecting rope 403 is provided in the fourth filter hole 402, and a fourth tail wing 404 is provided at the tail of the fourth connecting rope 403. The wind kinetic energy carried by the oil smoke will cause the fourth tail wing 404 to swing, and the fourth tail wing 404 drives the fourth connecting rope 403 to swing in the fourth filter hole 402. The fourth connecting rope 403 collides and falls off the attachments in the fourth filter hole 402, so that the fourth processing unit achieves a self-cleaning effect. Furthermore, the fourth tail wing 404 is in the form of a sheet, and under the action of the wind kinetic energy, the sheet structure is easier to swing. In some examples, the fourth connecting rope 403 is designed as a bendable and swingable connecting rope; in some examples, the fourth connecting rope 403 is designed as a chain, and the collision between the chain and the inner wall of the fourth filter hole 402 makes it easier to cause the attachments to fall off.

[0058] In the fourth filter plate 401, the fourth connecting ropes 403 in two adjacent fourth filter holes 402 are connected at their heads, and the two swinging fourth tail wings 404 drive one fourth connecting rope 403 to swing, and the swing amplitude of the fourth connecting rope 403 is larger.

[0059] The passage path in the fourth filter hole 402 is arc-shaped, thereby extending the path of the oil smoke in the fourth filter hole 402 and enhancing the adsorption effect of the fourth filter hole 402 on the oil smoke particles. The length of the fourth connecting rope 403 in the arc-shaped fourth filter hole 402 is correspondingly extended, and accordingly, the swing of the fourth connecting rope 403 in the fourth filter hole 402 is enhanced, and the self-cleaning effect is enhanced.

[0060] The fourth processing unit is provided with a fourth support member 406 for mounting the fourth filter plate 401 , and the fourth support members 406 are respectively arranged at the upper end and the lower end of the fourth filter plate 401 , and specifically, the cross section of the fourth support member 406 is arranged in an angular shape.

[0061] The fifth processing unit includes a fifth filter plate 408, which is disposed above the fourth processing unit. The fifth filter plate 408 filters and removes PM2.5 solid particles in the oil smoke.

When the discharge volume is large, the wind force pushes the floating shell 504 upward, and the air outlet on the side wall of the float 505 gradually moves upward and is exposed at the side, and the wind is sent out from the air outlet on the side wall of the float 505, increasing the air volume. After stopping the discharge, the floating shell 504 falls down to close the discharge unit, which has the effect of preventing rats, insects and backflow.

[0063] The inner wall of the fixed housing 501 is provided with a guide rail 502, and the side wall of the float 505 is provided with a guide groove 507 configured and installed with the guide rail 502.
