Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchen smoke treatment, in particular to a flue spray dust reduction device. Background Art
[0002] Commercial kitchens have relatively high standards for oil fume emissions, especially in Chinese restaurants, canteens, etc. The oil fume is relatively heavy and requires professional kitchen exhaust equipment that not only meets the emission requirements but also maintains a sanitary environment in the kitchen.
[0003] The existing smoke exhaust system only discharges the oil smoke generated in the kitchen directly to the outside through the flue, and there is no device to purify the oil smoke, or some kitchens install expensive oil smoke purification systems in the flue. In addition, there is also a method of spraying water into the flue to reduce smoke and dust from the oil smoke generated in the kitchen, but the sprayed water cannot completely cover the smoke and water tank, resulting in the inability to completely filter out the particles in the smoke, and the smoke temperature cannot be reduced. The smoke discharged to the outdoors will cause air pollution, and the collision flow of water and smoke is noisy, and it also causes a waste of water resources. Cleaning and maintenance are also relatively complicated. Utility Model Content
[0004] In view of the technical problems raised by the background technology, this utility model patent provides a flue spray dust reduction device, which is implemented by the following specific scheme:
[0005] Provided is a flue spray dust suppression device, comprising a water supply pipeline, a first spray module, and a second spray module, wherein the water supply pipeline is connected to the first spray module or the second spray module, the first spray module and the second spray module are arranged opposite to each other, and the two are connected by a bridge pipeline, wherein:
[0006] The first spray module includes a first water supply pipeline and a plurality of high-pressure water mist nozzles arranged on the first water supply pipeline, the first water supply pipeline includes at least two transverse pipelines and longitudinal pipelines located at both ends of the transverse pipeline and connected to the transverse pipeline, and the high-pressure water mist nozzles on the first water supply pipeline face the second spray module;
[0007] The second spray module includes a second water supply pipeline and a plurality of high-pressure water mist nozzles arranged on the second water supply pipeline. The second water supply pipeline includes at least two transverse pipelines and longitudinal pipelines located at both ends of the transverse pipelines and connected to the transverse pipelines.

[0008] According to a further preferred technical solution, the bridge pipe is connected to the transverse pipes and / or longitudinal pipes of the first water supply pipe and the second water supply pipe, and the bridge pipe is a telescopic pipe to adjust the distance between the first spray module and the second spray module.
[0009] According to a further preferred technical solution, the telescopic pipeline is formed by sleeve-connecting at least one small-diameter pipeline and at least one large-diameter pipeline, wherein the small-diameter pipeline can slide axially in the large-diameter pipeline.
[0010] According to a further preferred technical solution, the first spray module is arranged along an inner wall on one side of the flue, and the second spray module is arranged along an inner wall on the other side of the flue.
[0011] According to a further preferred technical solution, the first water supply pipeline and the second water supply pipeline have the same shape, and the high-pressure water mist nozzle of the first spray module and the high-pressure water mist nozzle of the second spray module are arranged opposite to each other.
[0012] According to a further preferred technical solution, the high-pressure water mist nozzles on the transverse pipes on both sides of the first spray module and / or the second spray module are staggered with the high-pressure water mist nozzles on the middle pipes.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.
[0021] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
[0022] See also Figure 1-Figure 4 The figure is a schematic diagram of the three-dimensional structure of a flue spray dust reduction device protected by the utility model, which includes a water supply pipeline 1, a first spray module 2, and a second spray module 3. The water supply pipeline 1 is connected to the first spray module 2 or the second spray module 3. In the figure, the water supply pipeline 1 is connected to the first spray module 2 below. The first spray module 2 and the second spray module 3 are arranged opposite to each other, and are connected by a bridge pipeline 4 in the middle.
[0023] Preferably, the first spray module 2 includes a first water supply pipeline 21 connected in a R shape, and three transverse pipelines 211, 212, and 213 of the R-shaped first water supply pipeline 21 are provided with multiple high-pressure water mist nozzles 22 facing the second spray module 3, and the three transverse pipelines 211, 212, and 213 are connected through longitudinal pipelines at both ends.
[0024] Correspondingly, the second spray module 3 includes a second water supply pipeline 31 that is connected in a rectangular shape. Further preferably, the second water supply pipeline 31 has the same shape as the first water supply pipeline 21. A plurality of high-pressure water mist nozzles 32 facing the first spray module 2 are provided on the three horizontal pipelines 311, 312, and 313 of the rectangular second water supply pipeline 31.
[0025] Of course, those skilled in the art can also design the number and length of the horizontal pipelines of the first water supply pipeline 21 and the second water supply pipeline 31 according to needs, such as two horizontal pipelines or more than three horizontal pipelines.
[0026] Further preferably, the bridging pipeline 4 can be connected to the horizontal pipelines of the first water supply pipeline 21 and the second water supply pipeline 31 or can also be connected to the vertical pipelines. The bridging pipeline 4 is a telescopic pipeline. Specifically, the bridging pipeline 4 is a sleeve, that is, one side is a small-diameter pipeline and the other side is a large-diameter pipeline. The small-diameter pipeline is inserted into the large-diameter pipeline, and the two are sealed by a seal. The small-diameter pipeline can slide in the large-diameter pipeline, so that the distance between the first spray module 2 and the second spray module 3 can be adjusted.
[0027] Further preferably, the first spray module 2 is arranged along one inner wall of the flue, and the second spray module 3 is arranged along the opposite inner wall of the flue. In this way, in the case of using the telescopic bridging pipeline 4, the first spray module 2 and the second spray module 3 can be as close as possible to the inner wall of the flue according to the size of the flue. The high-pressure water mist nozzles 22 and 32 of the two spray modules both spray water mist towards the center of the flue, thereby ensuring that all the smoke entering the flue passes through the water mist sprayed by the high-pressure water mist nozzles, greatly improving the effect of smoke removal and dust reduction. At the same time, the smoke has to pass through the water mist sprayed by multiple or multiple pairs of high-pressure water mist nozzles, improving the effect of smoke purification.
[0028] Further preferably, the high-pressure water mist nozzles 22 of the first spray module 2 are arranged opposite to the high-pressure water mist nozzles 32 of the second spray module 3, so that the relatively sprayed water mists collide with each other, making the water mist cover the entire cross-section of the flue as much as possible and improving the effect of smoke removal and dust reduction. In addition, combined with the scheme of the telescopic bridging pipeline 4, when the distance between the first spray module 2 and the second spray module 3 is adjusted to be small, the water mist collision effect can be improved.
[0029] Further preferably, the high-pressure water mist nozzles on the horizontal pipelines 211, 213, 311, and 313 on both sides of the first spray module 2 and / or the second spray module 3 are arranged offset from the high-pressure water mist nozzles on the middle pipelines 212 and 312. In this way, the coverage area of the water mist can be improved while reducing the number of high-pressure water mist nozzles, thereby reducing the cost of the entire device.
