Description

Technical Field

[0001] The present invention relates to the technical field of ventilation systems and air purification, and in particular to a pipeline guide plate device, specifically a device that can convert pipeline linear airflow into rotating airflow to advance, thereby agglomerating fine powder into agglomerates and quickly eliminating fine dust Pm2.5. Background Art

[0002] With the rapid development of modernization, although many achievements have been made, there are still some problems that need to be solved in the field of environmental protection, especially in the technical field of air purification.

[0003] For example: fine dust PM2.5, that is, fine particulate matter, refers to particles in the atmosphere with a diameter less than or equal to 2.5 microns, also known as respirable particles. Its harm is mainly manifested in the impact on human health, ecological environment and climate. PM2.5 cannot be ignored because of the serious harm it causes to health and the environment.

[0004] There are many kinds of existing air purification technologies, but most of them can only purify coarse dust particles of PM3 and above. It is difficult to eliminate this fine dust PM2.5 in the existing technology. There is electrostatic technology that can purify PM2.5, but it has the disadvantages of slow speed and poor purification accuracy. Bio-enzyme purification technology for PM2.5 has the disadvantage of too high cost.

[0005] For example: a pipeline guide plate structure CN202021855515.7 technology is mainly used for measuring flue gas flow and controlling flow rate. Its structure, effect, and use are not completely different from the present invention.

[0006] For example: A purification device for fine particulate matter treatment CN 201910827195.X Electrostatic dust removal technology: It is to input high voltage electricity into a device in a certain space, so that the dust in the air is positively charged, and the dust collecting plate in the space shell is negatively charged, so that the dust, including fine dust Pm2.5, is adsorbed on the dust collecting plate to achieve air purification. The advantage is: it can purify Pm2.5. The disadvantages are: high voltage electricity has a large electric field, and people and animals should stay away from it. Second, if there is a lot of organic dust in the air, it is easy to cause fire or even explosion. Third, it is better for slowly flowing air, otherwise the purification effect is poor.

[0007] For example: using bio-enzyme PM2.5 treatment technology, using composite bio-enzymes to decompose and transform PM2.5 and other fine particles in the air. Specifically, the active polymer components in the treatment agent carry positive charges and have strong adsorption and condensation effects, which make small solid particles in the air agglomerate and condense into small droplets with the liquid in the product, thereby purifying the air. This is a chemical, liquid, and is not the same technology as the present invention, and is expensive.

[0008] At the same time, in terms of filter technology, multiple filters are also used to filter fine dust Pm2.5, but the wind resistance is large and the mesh holes are easily blocked.

[0009] From the above, it can be seen that although the existing technology for purifying dust has made many progresses, there are still some shortcomings in purifying fine dust Pm2.5: either the purification speed is slow, or the volume is large, or the purification accuracy is poor, or the cost is too high.

[0010] These problems not only affect the development of the technical field of air purification, but also bring many adverse effects to human life and health.

[0011] In order to make up for the above technical deficiencies and achieve a better effect of purifying fine dust Pm2.5 in the air, a pipeline guide plate device that can aggregate fine powder into agglomerates was invented to solve the above technical problems. Summary of the invention

[0082] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0083] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0084] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0085] The present invention adopts the following technical solutions:

[0086] Technical solution (purification idea): First use conventional technology to filter out coarse dust above PM10 in the air, and then for fine dust below PM10, especially air containing PM2.5, use a pipe guide plate device to change the straight airflow into a rotating airflow, and with the participation of water mist or water droplets, aggregate the fine powder into agglomerates. At this time, PM2.5 will completely disappear and become coarse dust and dust-containing water droplets. Even if there is a small amount of dust, it is coarse dust; then use conventional centrifugal technology to dehydrate and remove dust, and finally under the filtration of the filter net HERA, the dust is quickly and thoroughly purified; the filter net HERA is used to filter the relatively clean air at the end.

[0087] This technology can be combined with any ventilation system and air purification system to upgrade it into a purification device with the function of quickly eliminating fine dust Pm2.5.

[0088] A pipeline guide plate and the components involved are characterized in that they are mainly composed of an exhaust fan or a blower, a ventilation pipeline, a pipeline guide plate, a water pump, a spray device, a filter screen, etc.

[0089] A pipeline guide plate, the structure involved is characterized by:

[0090] The exhaust fan or blower is installed at one end of the ventilation duct to make the air flow quickly when working. The duct guide plate is installed near the air inlet of the blower and fixed on the duct shell. The spray device is installed near the wind direction of the duct guide plate and fixed to the ventilation duct. The filter is installed at the air outlet of the ventilation duct and fixed to the ventilation duct.

[0091] A pipeline guide plate, the purification principle involved, is characterized by:

[0092] When the exhaust fan or blower is working, the air containing fine dust PM2.5 has a water spray device in the ventilation duct. With the participation of quantitative water mist or water droplets, the duct guide plate turns the duct straight airflow into high-speed rotating airflow. Under the centrifugal force and stirring force generated by the high-speed rotating airflow, plus the water film adsorption force, the fine dust quickly adheres to form a mass, turning into coarse dust and dust-containing water droplets, and then filtered through the filter. The purified clean air is discharged from the duct outlet.

[0093] Embodiment 1:

[0094] like Figure 1 , Figure 2 As shown:

[0095] The dust-containing air (101) is first filtered of coarse dust from the first filter (102) by the first exhaust fan (103), and then sent into the ventilation pipe (104) by the first exhaust fan (103). Under the action of the pipeline guide plate (108), a rotating airflow (112) is formed and continues to move forward. A spray device (110) is provided near the wind direction of the pipeline guide plate (108), and the amount of water is controlled by a water supply valve (109). The rotating airflow (112) continues to move forward, and the air containing fine dust Pm2.5, with the participation of a certain amount of water mist or water droplets in the ventilation pipe (104), the fine dust is quickly bonded into a mass under the action of the centrifugal force, stirring force and water film adsorption force generated by the high-speed rotating airflow (112), and the fine dust and water (111) and the medium-fine dust and dust-containing water droplets (113) are successively , and then become coarse dust and dust-containing water droplets (114), and enter the cylindrical filter room (105) tangentially along with the air from the ventilation duct (104); under the action of the second exhaust fan (107), it quickly enters the cylindrical filter room (105) tangentially to form a rotating upward airflow (116), and uses centrifugal force to remove the coarse dust and dust-containing water droplets (114); the air is then finely filtered by the second filter (106), and the clean air is discharged from the exhaust port (117); in order to save water resources, a dust-containing water retention pool (115) is designed, which is filtered in the water filter room (121) and becomes reclaimed water, which is connected to the water supply pipe of the purification system through a water pump (119) and a water supply pipe (120), so as to realize water recycling; the sewage and waste residues are discharged from the sewage outlet (118), and some of the sewage and waste residues can be recycled, such as being used as fertilizer for flowers and trees.

[0096] This purification method can not only purify fine dust, but also purify various water-soluble organic and inorganic substances in the air. This device is suitable for use in factories and mines with a lot of dust at the source.

[0097] Embodiment 2:

[0098] like Figure 3 , Figure 4The present invention relates to a pipeline guide plate device, belonging to the field of air purification, and specifically a device that can convert direct current gas in a pipeline into a rotating airflow to advance, thereby aggregating fine powder into a mass, and can quickly eliminate fine dust Pm2.5. The device mainly comprises an exhaust fan or a blower (302), a ventilation duct (301), a pipeline guide plate (303), a water spray device (304, 408), an air inlet (305), a water pump (406), a water outlet pipe (407), a filter (409), etc. When the power is turned on, when the exhaust fan or the blower (302) is working, air passes through the blower The air inlet (401) moves forward quickly, and under the action of the duct guide plate (303), a rotating airflow (306) moves forward. At this time, the air containing fine dust and water droplets (403) in the ventilation duct (301) is rapidly agglomerated into coarse dust and dust-containing water droplets (405) by the participation of water mist or water droplets provided by the water spray device (304) and the centrifugal force, stirring force, water film adsorption force, etc. generated by the high-speed rotating airflow (306). The clean air is then filtered through the filter (308) and discharged from the duct outlet.

[0099] The purified air can be discharged outdoors, or it can be purified outdoors to provide fresh air for indoor use, serving as a front-end purification device for a fresh air system. In order to save water, the dust-containing sewage (410) at the air outlet is filtered through a water filter (409) and then extracted by a water pump (406). The water outlet pipe (407) is connected to a water spray device (408), so that tap water can be recycled.

[0100] This device is suitable for purifying factory areas and clean rooms with air supply or fresh air systems with less dust at the source.

[0101] Embodiment three:

[0102] like Figure 5 , Figure 6 As shown: a duct guide plate device, the ventilation duct should be straight. In order to adapt to the specific production structure environment, the connected ventilation duct (507) can be curved, U-shaped, S-shaped or W-shaped, but try to use smooth connection to avoid right angles and sharp turns. In order to adapt to specific needs, it can be enlarged or reduced in proportion; according to the need to aggregate fine powder into agglomerates, a second duct guide plate (504) or multiple duct guide plates (502) can be added to the longer ventilation duct, and the air volume or vacuum degree of the exhaust fan can be increased at the same time, so that it is easier to aggregate fine dust into agglomerates and turn them into coarse dust and dust-containing water droplets (509); if the front end of the ventilation duct with the duct guide plate has water splashing, the ventilation duct does not need to be equipped with a water spray device; if there is a strong exhaust fan at the front end of the air outlet, this duct is no longer equipped with an exhaust fan.

[0103] Embodiment 4:

[0104] like Figure 7 , Figure 8 As shown: a duct guide plate (701) involved in a purification device for eliminating fine dust Pm2.5, when viewed from the main view of the duct guide plate air inlet (702), it looks like a stationary electric fan, but there is no motor in the center, and the peripheral duct guide plate blades (706) are fixed to the circular tubular shell (704); when viewed from the side, the angle between the duct guide plate blade (706) surface and the duct cross section is about 45 degrees, and the shell is circular. In order to reduce wind resistance, the outer shell diameter of the duct guide plate should be slightly larger than the diameter of the duct or ventilation duct.

[0105] In a purification device with a pipeline guide plate device, there are three factors that affect the purification effect of fine dust:

[0106] One is wind pressure or vacuum;

[0107] The second is the ratio of air volume to water mist;

[0108] The third is the length of time the airflow passes through the ventilation duct.

[0109] The use of a purification device with an upgraded pipeline guide plate solves the problem of difficulty in purifying fine dust Pm2.5 that is currently recognized in the industry, and solves the problems of high cost, large size, slow purification speed of fine dust Pm2.5, and poor purification accuracy of existing technologies. It can be widely used in ventilation and air supply systems and air purification fields.

[0110] For example: a U-shaped air duct connecting two filter cylinders in a blackboard purification vacuum cleaner is installed at the air inlet of the air duct (ventilation duct). The effect of purifying fine dust is significantly improved and the service life of the host is greatly extended.

[0111] For example: upgrading and transformation of air purification equipment in cement plants, talcum powder plants, paint plants, plastic spraying plants, furniture plants, decoration sites, fresh air systems, dust-free workshops, etc.; some precision manufacturing, military industry, medical, etc., which have high requirements for the purification rate of fine dust Pm2.5 in the air, and can be used in places where other purification methods are prohibited or not applicable, as well as smoke purification, fuel vehicle exhaust purification and other places.

[0112] In summary, the key technologies and innovations of the present invention are:

[0118] Principle: The direct air in the pipeline is transformed into a rotating airflow through the pipeline guide plate. Under the centrifugal force of the rotating airflow, the contact area between the water droplets and the air is increased by more than ten times compared with the direct air.

In addition, the water film has the ability to capture and bind dust quickly, so fine dust can easily and quickly aggregate into coarse dust.

[0119] Its technological breakthroughs and the effects they bring: improved performance.

[0120] Optimized combination technology:

[0121] If the pipeline guide plate technology is adopted, tap water with a cost of about three yuan per ton can be recycled to replace the biological enzyme PM2.5 treatment technology with a cost of more than three thousand yuan per ton, the same effect of purifying fine dust PM2.5 can be achieved, and the same large space can be purified. The comprehensive cost of the present invention is only about 5% of the biological enzyme PM2.5 treatment technology, and the purification speed is increased by about 10 times, which greatly reduces the cost and improves the timeliness.

[0126] After optimizing the combination of the pipeline guide plate, exhaust fan or blower, ventilation duct, pipeline guide plate, water pump, spray device, filter screen and other components, a new effect is achieved: the forward wind rotates with water mist, thereby aggregating fine powder into agglomerates;

[0127] Its technological breakthrough and the effect it brings: It solves the problem of difficulty in purifying fine dust Pm2.5 that is currently recognized in the industry.

[0128] A pipeline guide plate device solves the problem of difficulty in purifying fine dust Pm2.5 currently recognized in the industry, and solves the problems of high cost, large volume, slow purification speed of fine dust Pm2.5 and poor purification accuracy of existing technologies.

In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
