AI Technical Summary
Existing kitchen fume extraction and filtration systems suffer from incomplete fume extraction, high equipment costs, high power consumption, and easy clogging of filters. In particular, during the seasoning cooking process, the fumes do not condense and directly enter the filter, resulting in a shortened filter lifespan.
A condensation and purification device for cooking oil fumes is designed. By installing a fume extraction pipe on the pot lid and connecting it to a fan, the fumes first enter the condensation section for condensation and cooling before entering the filter. The condensation section includes plate and tubular condensers, and a collection tank collects the condensate, reducing the volume and flow of oil fumes, separating grease, and reducing the risk of leakage.
It improves the efficiency of oil fume purification, reduces maintenance costs, extends the service life of filters, reduces energy consumption, and enhances purification effects.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of condiment production technology, and in particular to a condensation and purification device for frying pan fumes. Background Technology
[0002] The cooking process of seasonings (such as hot pot base) generates a lot of oil fumes and heat, which not only affects the kitchen environment but also harms the health of the staff.
[0003] Currently, the market typically uses large-area exhaust and filtration systems installed above the kitchen. These systems generally include a fan and a filter. The fan provides negative pressure to force the fumes into the purification and filtration system, where the filter then filters the incoming fumes. This allows for the emission and purification of fumes.
[0004] However, due to the large kitchen space, there are not only problems with incomplete smoke extraction, but also with high equipment investment costs and high power consumption. Furthermore, the direct entry of high-temperature oil fumes into the filter makes it more prone to clogging, reducing the filter's service life and increasing maintenance costs. Utility Model Content
[0005] The purpose of this invention is to solve the problems of incomplete smoke extraction and uncondensed oil fumes entering the filter directly, which easily clogs the filter in the existing technology of installing a large-area exhaust and filtration system above the kitchen. Therefore, this invention proposes a frying pan oil fume condensation and purification device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A condensation and purification device for cooking fumes from a wok includes a frame-structured support and a collection tank fixedly mounted on the support. A condensation section is fixedly mounted on the collection tank, and a smoke inlet pipe is fixedly mounted at the input end of the condensation section. A fan is fixedly mounted at the end of the smoke inlet pipe away from the condensation section. The fan is connected to the lid of the wok via a smoke extraction pipe. When the fan is working, a negative pressure is generated in the smoke extraction pipe to draw in the fumes from the wok. An exhaust pipe is fixedly mounted on the condensation section, and a filter is fixedly installed at the output end of the exhaust pipe.
[0008] To facilitate the condensation of flue gas, preferably, the condensation section includes a plate condenser, and a tubular condenser is fixedly installed on the top of the liquid collection tank. The top of the tubular condenser is fixedly connected to the bottom of the plate condenser. The flue gas inlet end of the plate condenser is connected to the flue gas inlet pipe, and the flue gas inlet end of the tubular condenser is connected to the flue gas outlet end of the plate condenser. The condensate outlet end of the tubular condenser is connected to the inside of the liquid collection tank, and the exhaust pipe inlet pipe is connected to the flue gas inlet end of the tubular condenser.
[0009] To facilitate the introduction of cooling water into the plate condenser, a condensing plate array is further fixedly installed inside the plate condenser, and a first pipe and a second pipe are fixedly installed on the plate condenser. The two ends of the condensing plate array are respectively connected to the first pipe and the second pipe, and the first pipe is used to introduce cooling medium.
[0010] To facilitate the discharge of liquid generated during condensation, a condenser tube array is further fixedly installed inside the tubular condenser, with both ends of the condenser tube array connected to the flue gas inlet and the condensate outlet of the tubular condenser, respectively.
[0011] Furthermore, two sets of tubular condensers are symmetrically arranged. The second pipe is connected to the cooling medium inlet of one set of tubular condensers through the fifth pipe. The cooling medium outlet of one set of tubular condensers is connected to the cooling medium inlet of the other set of tubular condensers through the fourth pipe. The cooling medium outlet of the other set of tubular condensers is fixedly provided with a third pipe.
[0012] Preferably, the smoke extraction pipe is fixedly equipped with an exhaust pipe with a valve.
[0013] Compared with the prior art, this utility model provides a condensation and purification device for wok fumes, which has the following beneficial effects:
[0014] 1. This wok fume condensation and purification device, by installing a fume extraction pipe on the wok lid and connecting the fume extraction pipe to the fan input end, allows most of the fumes inside the wok to directly enter the fan through the fume extraction pipe and then enter the condensation section for condensation. Finally, it is discharged through the exhaust pipe to the filter for filtration and purification. In this process, not only can the possibility of fume leakage be reduced, but the fumes can also be condensed and cooled, which can reduce the volume and flow of fumes, separate some of the grease, increase purification efficiency, reduce maintenance costs, and improve the performance.
[0015] 2. This wok fume condensation and purification device has a liquid collection tank fixedly installed on the bracket, and a drain pipe fixedly installed on the liquid collection tank. This allows for the collection of the liquid generated by condensation, which is convenient for subsequent use and improves the usage effect.
[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model installs a smoke extraction pipe on the pot lid and connects the smoke extraction pipe to the input end of the fan. Most of the smoke in the wok can directly enter the fan through the smoke extraction pipe and then enter the condenser for condensation. Finally, it is discharged through the exhaust pipe to the filter for filtration and purification. In this process, not only can the possibility of smoke leakage be reduced, but the smoke can also be condensed and cooled, which can reduce the volume and flow of oil fumes, separate some grease, increase purification efficiency, reduce maintenance costs, and improve the use effect.

[0024] Example:
[0025] Reference Figures 1-4A condensation and purification device for frying pan fumes includes a frame-structured support 1. A collection tank 101 is fixedly mounted on the top of the support 1, and a drain pipe 102 with a valve is fixedly mounted on the bottom of the collection tank 101 to discharge the condensate accumulated in the collection tank 101, improving the efficiency. A condensation section is fixedly mounted on the collection tank 101, and a smoke inlet pipe 4 is fixedly mounted at the input end of the condensation section. A fan 5 is fixedly mounted at the end of the smoke inlet pipe 4 away from the condensation section, and the input end of the fan 5 is used for smoke extraction. Pipe 6 is connected to the lid of the wok. When the fan 5 is working, a negative pressure is generated in pipe 6 to draw in the fumes from the wok. Multiple woks with lids are installed here, with the lids raised and lowered on the woks. There are two to ten sets of woks; here, we prefer four sets, each located on a mounting frame. A lifting rod is installed on the mounting frame, and the lid is fixedly connected to the output end of the lifting rod. The lifting rod can raise and lower the lid onto the wok. The lifting rod is preferably cylinder-driven. This means that each set of pot lids is fixedly equipped with a smoke extraction pipe 6. The fumes generated in the wok can directly enter the fan 5 through the smoke extraction pipe 6, and then enter the condenser section through the smoke inlet pipe 4. Here, the smoke extraction pipe 6 is divided into two sections: the section near the fan 5 is a fixed stainless steel pipe, and the section near the pot lid is a retractable stainless steel pipe. This allows it to move up and down with the pot lid when it is raised or lowered, improving the efficiency. In addition, an exhaust pipe 8 is fixedly installed on the condenser section. A filter is fixedly installed at the output end of the exhaust pipe 8. The filter is a rotating cylindrical filter with activated carbon inside. The filter is fixed to the exhaust pipe 8 through a flange. When the fan 5 is working, the fumes in the wok enter the condenser section through the smoke extraction pipe 6 and the smoke inlet pipe 4 for condensation. After condensation, it is discharged through the exhaust pipe 8 to the filter for filtration and purification. The filter is preferably an activated carbon plate. The condensation pretreatment technology is introduced before the oil fume purification. By cooling, the volatile organic compounds (VOCs) and oil particles in the oil fume are condensed into liquid, which can significantly improve the subsequent purification effect. Condensation technology can not only reduce the volume and flow of oil fumes, but also separate some of the grease, creating more favorable conditions for subsequent purification processes, while reducing energy consumption and equipment wear.
[0026] During use, by installing a smoke extraction pipe 6 on the pot lid and connecting the smoke extraction pipe 6 to the input end of the fan 5, most of the fumes in the wok can directly enter the fan 5 through the smoke extraction pipe 6 and then enter the condenser for condensation. Finally, they are discharged through the exhaust pipe 8 to the filter for filtration and purification. In this process, not only can the possibility of fumes leakage be reduced, but the fumes can also be condensed and cooled, which can reduce the volume and flow of oil fumes, separate some grease, increase purification efficiency, reduce maintenance costs, and improve the performance.
[0027] Reference Figures 2-4Here, we design the condensation section as a plate condenser 2, with a tubular condenser 3 fixedly installed on the top of the liquid collection tank 101. The top of the tubular condenser 3 is fixedly connected to the bottom of the plate condenser 2. The flue gas inlet of the plate condenser 2 is connected to the flue gas inlet pipe 4, and the flue gas inlet of the tubular condenser 3 is connected to the flue gas outlet of the plate condenser 2. The condensate outlet of the tubular condenser 3 is also connected to the inside of the liquid collection tank 101, allowing for the collection of the condensed liquid. Furthermore, the exhaust pipe 8 is connected to the flue gas inlet of the tubular condenser 3. The ends are connected. After being condensed by the plate condenser 2, the flue gas enters the tubular condenser 3 and can be discharged from the exhaust pipe 8. Both the plate condenser 2 and the tubular condenser 3 are existing technologies. In use, the fan 5 is started to draw the flue gas from the wok through the smoke extraction pipe 6, and then it enters the plate condenser 2 through the smoke inlet pipe 4 for condensation and cooling. After condensation, it can be discharged from the exhaust pipe 8 when entering the tubular condenser 3 and enter the filter for purification and filtration. The liquid produced by condensation can enter the liquid collection tank 101 for subsequent treatment.
[0028] Reference Figure 4 A condenser plate array 201 is fixedly installed inside the plate condenser 2. A first pipe 202 and a second pipe 203 are fixedly installed on the plate condenser 2. The two ends of the condenser plate array 201 are connected to the first pipe 202 and the second pipe 203 respectively. The first pipe 202 is used to introduce a cooling medium, which can be a low-temperature gas or liquid. Here, we prefer a liquid. In use, cooling water is introduced into the first pipe 202. The cooling water flows along the condenser plate array 201 and finally collects in the second pipe 203 for convenient subsequent use.
[0029] Reference Figure 4 A condenser tube array 304 is fixedly installed inside the tubular condenser 3, and the two ends of the condenser tube array 304 are connected to the flue gas inlet and the condensate outlet of the tubular condenser 3, respectively. During use, the condensate can pass through the condenser tube array 304 and enter the liquid collection tank 101. During this process, the tubular condenser 3 can cool the passing condensate for subsequent use.
[0030] Reference Figure 4Here, we symmetrically arrange two sets of tubular condensers 3. The second pipe 203 is connected to the cooling medium inlet of one set of tubular condensers 3 through the fifth pipe 303. The cooling medium outlet of one set of tubular condensers 3 is connected to the cooling medium inlet of the other set of tubular condensers 3 through the fourth pipe 302. The cooling medium outlet of the other set of tubular condensers 3 is fixedly provided with a third pipe 301. That is to say, the cooling water flowing out from the second pipe 203 can enter the cooling medium inlet of one set of tubular condensers 3 through the fifth pipe 303, then flow out from the cooling medium outlet of one set of tubular condensers 3, and enter the cooling medium inlet of the other set of tubular condensers 3 through the fourth pipe 302, and finally be discharged from the third pipe 301. The residual heat of the cooling water can be utilized in the tubular condensers 3 to improve the performance.
[0031] Reference Figures 2-4 A discharge pipe 7 with a valve is fixedly installed on the smoke extraction pipe 6, which can discharge liquids and oil stains in the smoke extraction pipe 6 and improve the use effect.
