Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater cleaning equipment for smoke exhaust pipes, and particularly relates to a rainwater cleaning device for smoke exhaust pipes. Background Technique
[0002] With the acceleration of the urbanization process and the increase in high-rise buildings, as an important part of buildings, the design and maintenance of smoke exhaust pipes have received increasing attention. Traditional smoke exhaust pipe designs usually focus on their smoke exhaust efficiency, while insufficient consideration is given to the cleaning and maintenance inside the pipes. In recent years, with the enhancement of environmental awareness and the increasing tension of water resources, people have begun to seek methods to use natural water sources such as rainwater for pipe cleaning, in order to reduce water resource waste and improve the service life of pipes. A large number of researches and practices have been carried out in this field at home and abroad, and a variety of rainwater utilization and pipe cleaning technologies have been developed, but most of these technologies are still in the primary stage and no mature solutions have been formed.
[0003] Existing rainwater cleaning technologies for smoke exhaust pipes have deficiencies in many aspects. First of all, many technologies fail to fully consider the cleaning efficiency of oil fume attachments during design, resulting in poor cleaning effects. A large amount of oil dirt still accumulates inside the pipes, affecting the smoke exhaust efficiency and increasing the fire risk. Secondly, when realizing rainwater utilization, existing technologies often ignore the problem of oil-water separation, making the water after cleaning unable to be effectively recycled, resulting in resource waste. In addition, the maintenance cost of existing technologies is relatively high, and regular manual cleaning is required, which not only increases the labor cost but also poses operation safety risks.
[0004] The differences in key technical means lie in that existing technologies mostly adopt simple physical interception or chemical cleaning methods. Although these methods can remove oil dirt to a certain extent, it is difficult to achieve long-term maintenance that is efficient, economical, and safe. For example, some technologies adopt a fixed-interval cleaning cycle and cannot be flexibly adjusted according to the actual accumulation of oil fume, resulting in low cleaning efficiency. At the same time, existing technologies often fail to fully consider the complexity of the pipe structure during design, making it easy to have dead corners during the cleaning process and difficult to achieve comprehensive cleaning.
[0005] Facing many difficulties in solving the defects of existing technologies, such as low oil-water separation efficiency, incomplete cleaning, high maintenance cost, etc. The existence of these problems not only limits the service life of smoke exhaust pipes but also affects the overall safety performance of buildings. The defects of existing technologies correspond to the problems to be solved, such as cleaning efficiency, resource recycling, maintenance cost, and operation safety, etc. These are all the key technical problems that need to be solved in this invention.
[0006] How to solve the above problems is the research focus of this solution. Content of the Utility Model
[0007] In order to achieve the above-mentioned purpose of the utility model and to address the above-mentioned technical problems, the utility model provides a rainwater cleaning device for a smoke exhaust duct.
[0008] The technical solution is as follows: a rectangular frame is arranged at one end of the smoke exhaust pipe, a guide pipe is arranged above the rectangular frame, a rainwater inlet is arranged at the top of the guide pipe, an insect and dustproof net is arranged at the rainwater inlet, an oil separator is arranged in the rectangular frame, an oil storage grid is arranged at the bottom of the rectangular frame, and a sewage pipe is connected to the bottom of the oil storage grid;
[0009] A fan and an oil fume purifier are arranged on the smoke exhaust duct, and the rectangular frame is located on a side of the fan away from the oil fume purifier.
[0010] An inspection opening is arranged at one end of the bottom of the rectangular frame.
[0011] The oil separator is made of 0.75 specification galvanized steel plate, with an area of 0.5 square meters, and is used to prevent the cleaned oil stains from flowing back.
[0012] The oil storage grid has a depth of 10 cm and is used to store the cleaned grease.
[0013] The sewage pipe adopts a UPVC pipe of DN50 specification, and the lowest end of the oil storage grid is connected to the main sewage pipe through the sewage pipe to achieve smooth discharge of oil stains.
[0014] The sewage pipe is provided with an inspection port of DN50 specification.
[0015] The specification of the inspection port is 150*150.
[0016] The oil separator is arranged obliquely, with the higher end connected to one side of the top of the rectangular frame and the lower end located just below the guide pipe.
[0017] Install oil separators, set up oil storage grids, and connect DN50 UPVC pipes to the main sewage pipe to achieve the purpose of cleaning the oil fume attachments on the inner wall of the pipe with rainwater.
[0018] Regularly check the cleanliness of the oil separator, clean the grease in the oil storage grid, and check the unobstructed state of the UPVC pipe to ensure the continuous and effective operation of the device.
[0019] The smoke exhaust pipe rainwater cleaning device realizes the guidance, filtration, oil-water separation and collection and discharge of oil dirt by setting a rectangular frame, a diversion pipe, an insect-proof and dust-proof net, an oil separator, an oil storage grid and a sewage pipe. The setting of the fan and the oil fume purifier ensures the smoke exhaust efficiency and air quality.
[0020] Beneficial effects: This design can effectively use rainwater to clean the smoke exhaust duct, reduce the need for manual cleaning, save costs, while keeping the duct clean and improving smoke exhaust efficiency.
[0021] An inspection port is set at the bottom of the rectangular frame to facilitate inspection and maintenance of the internal structure. The setting of the inspection port improves the maintainability of the device, facilitates timely discovery and resolution of problems, and ensures long-term stable operation of the device.
[0022] The grease trap is made of 0.75 gauge galvanized steel plate, which has high strength and corrosion resistance. The use of this material grease trap can improve the durability of the device, reduce maintenance frequency and extend service life.
[0023] The depth of the oil storage grid is designed to be 10cm, which provides enough space for the collection of grease. The appropriate depth of the oil storage grid can ensure that grease is effectively collected, prevent grease from overflowing, and reduce environmental pollution.
[0024] The sewage pipe adopts DN50 UPVC pipe to ensure smooth sewage discharge. Using UPVC pipe as sewage pipe has good chemical corrosion resistance and fluidity, which can effectively transport grease to the main sewage pipe and reduce the risk of blockage.
[0025] A DN50 inspection port is set on the sewage pipe for easy inspection and cleaning. The setting of the inspection port improves the maintainability of the sewage pipe, facilitates regular inspection and cleaning, and prevents pipe blockage.
[0026] The inspection port is 150*150 in size, providing sufficient operating space. The appropriate size of the inspection port facilitates internal inspection and maintenance by the staff, improving the efficiency and safety of maintenance.
[0027] The oil separator is tilted to make the oil-water separation more efficient by using the principle of gravity. The tilted design of the oil separator can speed up the oil-water separation process, making it easier for oil and dirt to flow to the oil storage grid, thus improving the efficiency of oil-water separation.
