Description

Technical Field

[0001] The invention relates to the technical field of ventilation and air-conditioning systems, and in particular to a spray dust removal temperature regulating device. Background Art

[0002] The special climatic conditions in windy and sandy areas, such as frequent sandstorms, extreme dryness, and extremely cold temperatures, place stringent requirements on the design of air conditioning units. The air conditioning system in such an environment must not only maintain a stable air supply volume and air quality, but also deal with the wear and blockage of equipment caused by high concentrations of sand and dust. Especially in densely populated office areas, the requirements for fresh air quality are even more stringent.

[0003] In windy and sandy areas, when the air conditioning unit uses a plate filter for air dust removal, the filter is easily clogged in a windy and sandy environment, and the filter element needs to be replaced frequently. In the prior art, air spraying is used instead of plate filters to remove dust from the air in windy and sandy areas. In addition to dust removal, air spraying can also be used for air evaporative cooling and humidification in summer. However, in windy and sandy weather, the sewage formed after the spray water contacts the dusty air circulates in the air conditioning system. As the soil accumulates in the water flow, the spray water flow rate and the service life of the circulating water pump will be seriously reduced, thereby affecting the dust removal and temperature regulation efficiency. Summary of the invention

[0004] In view of this, the present invention provides a spray dust removal temperature adjustment device to solve the problem that the operating efficiency of the spray dust removal ventilation and air-conditioning system installed in windy and sandy areas will be greatly reduced during long-term operation.

[0005] The present invention provides a spray dust removal temperature regulating device, comprising:

[0006] A ventilation channel, with baffles at the bottom of both ends, a spray assembly installed in the inner cavity of the ventilation channel, the spray assembly is arranged perpendicular to the airflow direction inside the ventilation channel, a sewage outlet is arranged at the bottom of the ventilation channel, and a blocking piece is detachably installed on the sewage outlet;

[0007] A circulating water storage member is installed in the ventilation channel, the circulating water storage member is arranged close to the bottom of the ventilation channel, the circulating water storage member is provided with an inlet, and a filter baffle is installed on the inlet;

[0008] A circulation driving member, one end of which is communicated with the circulation water storage member, and the other end of which is communicated with the spray assembly.

[0009] The spray dust removal temperature regulating device is suitable for installation in windy and sandy areas and is used as a spray dust removal section in the air conditioning system. The spray assembly arranged perpendicular to the airflow direction in the inner cavity of the ventilation channel disperses and sprays the circulating water, which is fully in contact with the air blown into the ventilation channel. The sand and dust particles are adsorbed by water droplets, so that the sand and dust particles in the air are adsorbed and gathered into large particles and fall into the inner cavity of the ventilation channel with the water flow under the action of gravity. The turbid liquid that falls into the ventilation channel after spraying gathers at the bottom of the ventilation channel under the blocking effect of the baffle at the bottom of the ventilation channel. The mud in the turbid liquid gradually settles, and the turbid liquid is filtered and purified by the filter partition from the inlet and enters the circulating water storage part. The filter partition can intercept large particles of sediment to prevent sediment from entering the water circulation pipeline. The circulation drive part drives the water in the circulating water storage part to circulate and transport it to the spray assembly. The mud and sand accumulated at the bottom of the circulating water storage part can be discharged regularly through the sewage outlet, which can prevent the mud from entering the water circulation pipe with the water flow and affecting the spray water flow and circulating water pump, thereby ensuring the temperature regulation efficiency of the spray dust removal air-conditioning system in windy and sandy areas under long-term use conditions.

[0010] In an optional embodiment, the spray assembly includes a circulating water main pipe and a circulating water branch pipe, wherein the circulating water branch pipe is arranged in multiple groups at intervals along the axial direction of the circulating water main pipe, and a spray nozzle is installed on the circulating water branch pipe. The circulating water main pipe is distributed along the length of the spray section, and the water flow is dispersed to different areas through multiple groups of axially spaced branch pipes. The nozzle disperses the water and sprays it out to cover the cross section of the ventilation channel. The circulating water main pipe cooperates with multiple circulating water branches to expand the spray coverage range, increase the contact area between the air and the circulating water sprayed by the spray assembly, and enhance the dust removal efficiency and evaporative cooling efficiency.

[0011] In an optional embodiment, a plurality of spray nozzles are arranged at intervals along the circulating water branch pipe, and two adjacent spray nozzles are respectively installed on both sides of the circulating water branch pipe along the axial direction. When the driving member delivers water to the circulating water branch pipe, the spray nozzles on both sides spray water at the same time to spray the air. The spray water forms a more uniform water mist in the ventilation channel, effectively increasing the contact area with the dust-laden air and improving the dust removal effect. At the same time, the air and water can be fully contacted, which is conducive to achieving more efficient evaporative cooling and humidification functions in summer.

[0012] In an optional embodiment, the circulating water storage part is provided with an auxiliary opening, and a closed cover is detachably mounted on the auxiliary opening. During normal operation, the closed cover ensures the sealing of the circulating water storage part to prevent impurities from entering. When it is necessary to inspect, clean, or add chemicals to the inside of the circulating water storage part, the closed cover is opened to facilitate the operator to maintain the inside of the circulating water storage part.

[0013] In an optional embodiment, the top surface of the circulating water storage member is inclined. The sprayed water flows along the inclined top surface to the bottom of the ventilation channel under the action of gravity, which is convenient for the centralized collection and recycling of water, and is also conducive to preventing water from accumulating on the top of the circulating water storage member, avoiding corrosion of the circulating water storage member caused by water accumulation.

[0014] In an optional embodiment, a water filter is installed between the circulation drive member and the circulation water storage member. The circulating water is filtered twice by the water filter to remove residual fine particles before being pumped to the spray nozzle, thereby protecting the circulation drive member and the spray nozzle from blockage and ensuring stable spray pressure.

[0015] In an optional embodiment, the inlet is arranged on the side of the circulating water storage part, and the distance between the inlet and the bottom of the ventilation channel is preset. When the turbid liquid after spraying flows into the circulating water storage part along the bottom of the ventilation channel, since the inlet is higher than the bottom of the ventilation channel, the larger particles of sediment naturally settle at the bottom of the ventilation channel under the action of gravity, while the upper water body containing less suspended matter enters the circulating water storage part through the inlet on the side. The height difference is used to achieve gravity sedimentation of dust and sediment, reduce the amount of sediment entering the circulation system, and reduce the load of the filter partition.

[0016] In an optional embodiment, a water level gauge is installed in the circulating water storage member. The water level gauge monitors the water level in the circulating water storage member in real time. When the water level is lower than the set minimum water level, the water replenishing device is started to replenish water, ensuring that there is always enough water in the circulating water storage member for circulating spraying, ensuring the normal operation of the equipment, and avoiding problems such as spraying interruption due to water shortage.

[0017] In an optional embodiment, a turbidity test component is installed in the ventilation channel. When the turbidity of the liquid in the ventilation channel measured by the turbidity test component is greater than a preset value, the sealing member is opened to discharge sewage. During the spraying process, the turbidity test component monitors the turbidity of the liquid falling into the ventilation channel after spraying in real time. Once the turbidity exceeds the preset value, it means that the liquid contains too much impurities such as mud and sand. At this time, the sealing member on the sewage outlet is opened to discharge the turbid liquid until the turbidity of the liquid accumulated in the ventilation channel drops to a reasonable range, thereby ensuring the cleanliness of the spray water and maintaining a good dust removal effect.

[0018] In an optional embodiment, the cross-sectional shape of the inner cavity of the ventilation channel perpendicular to the flow direction of the airflow inside the ventilation channel is circular. When air flows through the ventilation channel with a circular cross-section, the airflow resistance can be effectively reduced, so that the airflow is more evenly distributed in the entire channel, which is conducive to the full contact between the spray water and the air, improves the spray dust removal effect, and also reduces the energy loss in the ventilation process, and improves the operation efficiency of the equipment.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] Combine the following Figure 1 and Figure 2 , describing an embodiment of the present invention.

[0025] According to an embodiment of the present invention, on the one hand, a spray dust removal temperature adjustment device is provided, comprising a ventilation channel 1, a water tank as a circulating water storage component 2 and a circulating water pump as a circulating driving component 3.

[0026] Baffles are provided at the bottom of both ends of the ventilation channel 1, a spray assembly 4 is installed in the inner cavity of the ventilation channel 1, and the spray assembly 4 is arranged perpendicular to the airflow direction inside the ventilation channel 1. A sewage outlet 5 is provided at the bottom of the ventilation channel 1, and a plugging member is detachably installed on the sewage outlet 5. A circulating water storage member 2 is installed in the ventilation channel 1, and the circulating water storage member 2 is arranged near the bottom of the ventilation channel 1. An inlet is provided on the circulating water storage member 2, and a filter baffle 6 is installed on the inlet. One end of the circulating drive member 3 is connected to the circulating water storage member 2, and the other end is connected to the spray assembly 4.

[0027] The spray dust removal temperature regulating device is suitable for installation in windy and sandy areas and is used as a spray dust removal section in an air conditioning system. The spray assembly 4 arranged perpendicular to the airflow direction in the inner cavity of the ventilation channel 1 disperses and sprays the circulating water, which is fully in contact with the air blown into the ventilation channel 1. The dust particles are adsorbed by the water mist, so that the dust particles in the air are adsorbed to each other and gathered into large particles and fall into the inner cavity of the ventilation channel 1 with the water flow under the action of gravity. The turbid liquid that falls into the ventilation channel 1 after spraying is blocked by the baffle at the bottom of the ventilation channel 1 and gathers at the bottom of the ventilation channel 1. The soil in the turbid liquid gradually settles. The turbid liquid is filtered and purified by the filter partition 6 from the inlet and enters the circulating water storage part 2. The filter partition 6 can intercept large particles of sediment to prevent sediment from entering the water circulation pipeline. The circulation drive part 3 drives the water in the circulating water storage part 2 to circulate and transport it to the spray assembly 4. The mud and sand accumulated at the bottom of the circulating water storage part 2 can be discharged regularly through the drain outlet 5, which can prevent the mud from entering the water circulation pipe along with the water flow and affecting the spray water flow and the circulating water pump, thereby ensuring the temperature regulation efficiency of the spray dust removal air-conditioning system in windy and sandy areas under long-term use conditions.

[0028] In this embodiment, two baffles are respectively arranged at both ends of the inlet and outlet of the ventilation channel 1. The turbid liquid accumulates in the ventilation channel 1 under the action of the baffles. In order to prevent the sewage in the ventilation channel 1 from flooding the spray assembly 4 and causing blockage of the spray assembly 4, the bottom position of the spray assembly 4 is higher than the top of the baffle. Specifically, the circulating water storage part 2 is arranged in a fan shape at one side of the bottom of the ventilation channel 1, and the bottom of the spray assembly 4 is flush with the top of the circulating water storage part 2.

[0029] In one embodiment, the spray assembly 4 includes a circulating water main pipe 7 and a circulating water branch pipe 8, wherein the circulating water branch pipe 8 is arranged in multiple groups at equal or non-equal intervals along the axial direction of the circulating water main pipe 7, and each group of circulating water branch pipes 8 is installed with multiple spray nozzles 9. The circulating water main pipe 7 extends horizontally along the horizontal direction of the cross section of the ventilation channel 1, and the circulating water branch pipe 8 is arranged longitudinally along the vertical direction of the cross section of the ventilation channel 1. The water flow is dispersed to different areas of the ventilation channel 1 through multiple groups of circulating water branch pipes 8. The spray nozzle 9 disperses the circulating water and sprays it out to form a uniform water mist covering the cross section of the ventilation channel 1. The combined design of the circulating water main pipe 7 and the circulating water branch pipe 8 expands the spray coverage range, can increase the contact area between the dust-laden air and the water droplets, and thus enhance the dust removal efficiency. As an alternative embodiment, the circulating water branch pipe 8 can be designed as a bifurcated or radial layout to adapt to the ventilation channel 1 with different cross-sectional shapes; the spray nozzle 9 can be designed with an adjustable angle to dynamically adjust the spray direction according to the air flow velocity.

[0030] In one embodiment, multiple spray nozzles 9 are arranged at staggered intervals on both sides of the axial direction of the circulating water branch pipe 8, and two adjacent spray nozzles 9 are respectively located on the left and right sides of the circulating water branch pipe 8. When the circulating drive 3 delivers pressurized water to the circulating water branch pipe 8, the spray nozzles 9 on both sides spray water synchronously, forming multiple groups of jet sprays in the ventilation channel 1, making the water mist distribution more uniform, avoiding the occurrence of spray blind spots in local areas, thereby maximizing the contact area with dusty air and improving dust removal efficiency. At the same time, dense water mist coverage can achieve more efficient evaporative cooling and humidification functions in summer.

[0031] In one embodiment, an auxiliary opening is provided on the side or top of the circulating water storage part 2. The auxiliary opening in this embodiment is provided on the top of the circulating water storage part 2. The auxiliary opening is detachably mounted with a closed cover plate 10 by means of a bolt connection or a snap-on structure. When the equipment is operating normally, the closed cover plate 10 ensures the sealing of the circulating water storage part 2 to prevent the intrusion of external impurities. When it is necessary to perform internal maintenance, sediment cleaning, or adding corrosion inhibitors, the operator can remove the closed cover plate 10 and directly contact the inside of the water storage part, which significantly simplifies the maintenance process. In some other embodiments, the auxiliary opening can be designed as an observation window with transparent pressure-resistant glass embedded in it to facilitate real-time monitoring of the internal status; the closed cover plate 10 can be integrated with a sealing gasket or an airtight locking device to enhance the sealing reliability.

[0032] In one embodiment, the top surface of the circulating water storage member 2 is inclined from the inside to the outside, and the inclination slope ranges from 3‰ to 10‰. In this embodiment, the inclination slope of the top surface of the circulating water storage member 2 is 5‰. The turbid liquid after spraying flows along the inclined top surface to the bottom of the ventilation channel 1 under the action of gravity, accelerating the convergence of water flow and reducing the retention time of the turbid liquid at the top of the circulating water storage member. It is convenient for the centralized collection and recycling of the turbid liquid at the bottom of the ventilation channel 1, preventing the corrosion or microbial growth caused by water accumulation on the top surface of the circulating water storage member, and extending the life of the equipment.

[0033] In one embodiment, the inlet end of the circulating water pump as the circulating driving part 3 is connected to the bottom of the water tank as the circulating water storage part 2 through a water pipe, and the output end of the circulating water pump is connected to the spray assembly 4 through a water pipe. A switch valve 12 and a water filter 11 are installed on the water pipe between the circulating driving part 3 and the circulating water storage part 2. The switch valve 12 is used to control the on-off of the circulating water pipeline. The circulating water is filtered twice by the water filter 11 before entering the circulating water pump to remove the remaining fine sediment and suspended matter with a particle size not greater than 0.1 mm, thereby protecting the circulating water pump and the spray nozzle 9 from clogging and ensuring that the spray pressure is stable at more than 2 bar. After removing the remaining fine particles, it is pumped to the spray nozzle 9 to protect the circulating driving part 3 and the spray nozzle 9 from clogging and ensure that the spray pressure is stable.

[0034] In one embodiment, the inlet is arranged on the side of the circulating water storage part 2, and a preset height difference is maintained between the lower edge of the inlet and the bottom of the ventilation channel 1. Before the turbid liquid after spraying flows from the bottom of the ventilation channel 1 to the inside of the circulating water storage part 2, the larger particles of sediment first settle to the bottom of the ventilation channel 1 due to gravity, and the upper layer of water containing less suspended matter enters the circulating water storage part 2 through the inlet. The height difference design can achieve the pre-separation of coarse particles of sediment and reduce the filtering load of the filter partition 6.

[0035] In one embodiment, a water level gauge is installed in the circulating water storage part 2, and the water level gauge can be a float type, a capacitive type or an ultrasonic type sensor. The water level gauge monitors the water level in the circulating water storage part 2 in real time. When the water level is lower than the set minimum water level, the water replenishing device is started to replenish water, ensuring that there is always enough water in the circulating water storage part 2 for circulating spraying, ensuring the normal operation of the equipment, and avoiding problems such as spraying interruption due to water shortage.

[0036] In one embodiment, a turbidity testing component is installed in the ventilation channel 1. When the turbidity of the liquid in the ventilation channel 1 measured by the turbidity testing component is greater than a preset value, the plugging piece is opened to discharge sewage. Specifically, when the turbidity of the liquid in the ventilation channel 1 measured by the turbidity testing component exceeds 5NTU, the plugging piece is opened to discharge sewage until the turbidity of the liquid drops to 1NTU, and then the plugging piece is closed. During the spraying process, the turbidity testing component monitors the turbidity of the liquid that falls into the ventilation channel 1 after spraying in real time. Once the turbidity exceeds the preset value, it means that the liquid contains too much impurities such as mud and sand. At this time, the plugging piece on the sewage outlet 5 is opened to discharge the turbid liquid until the turbidity of the liquid accumulated in the ventilation channel 1 drops to a reasonable range, thereby ensuring the cleanliness of the spray water and maintaining a good dust removal effect.

[0037] In one embodiment, the cross-sectional shape of the inner cavity of the ventilation channel 1 perpendicular to the flow direction of the airflow inside the ventilation channel 1 is circular. When the airflow passes through the ventilation channel 1 with a circular cross-section, the airflow resistance can be effectively reduced, and the airflow is more evenly distributed in the entire channel, which is conducive to the full contact between the spray water and the air, and improves the spray dust removal effect. At the same time, it also reduces the energy loss during the ventilation process and improves the operating efficiency of the equipment. In some other embodiments, the inner wall of the ventilation channel 1 with a circular cross-section can be covered with a hydrophobic coating to reduce the adhesion of water droplets.

[0038] The spray dust removal temperature regulating device provided in this embodiment provides a circular air conditioning unit spray section structure for the characteristics of windy and sandy climate conditions, adopts a water tank embedded design, and controls the automatic discharge of turbid liquid through real-time turbidity monitoring, which can be directly applied to the design of air conditioning units in related fields. Compared with the traditional square, the circular shell structure of the ventilation channel 1 has high air flow uniformity and low air leakage rate. Using air spray means instead of traditional plate filters for air dust removal can effectively reduce the replacement frequency of the filter element and reduce operating costs. The spray section water tank as a circulating water storage part adopts an embedded design, which can reduce the space occupied by the equipment. The discharge of turbid liquid is controlled by real-time turbidity monitoring, which improves the level of automation and brings convenience to the operating personnel. The cross-section of the circular shell of the ventilation channel 1 is a circular structure, and the material is stainless steel. In sandstorm weather, the dusty air is sent into the ventilation channel 1 for spraying and washing to reduce the dust content of the air. In summer, it also serves as direct evaporative cooling and cooling, and in dry climates, it can also serve as a humidification function. The circulating water tank is embedded, and the circulating water can effectively filter the sediment. The internal and external structures of the spray section have anti-dust design. A horizontal circulating water main pipe 7 is set in the middle of the ventilation channel 1. A vertical circulating water branch pipe 8 is set at the same interval on the circulating water main pipe 7. Nozzles are cross-set in the horizontal direction on the circulating water branch pipe 8. The nozzle spray pressure is ≥2bar. A large-diameter nozzle is preferably used to prevent nozzle clogging. The nozzle spray hole diameter is greater than 4mm. A fan-shaped spray water tank is set at the bottom of the ventilation channel 1 as a circulating water storage part. A filter baffle 6 is set in the vertical direction of the water tank to filter the turbid liquid generated by the contact between the spray water and the dusty air, and prevent large particles of sediment from entering the circulating water tank. The top of the spray water tank is set with a slope of 5‰ from the outside to the inside to prevent water accumulation on the top of the water tank, and an inspection cover is set for regular personnel inspection and cleaning. A turbid liquid discharge outlet is set at the bottom of the ventilation channel 1, and a concentration meter is set at the turbid liquid measurement for real-time monitoring. When the turbidity exceeds 5NTU, it is drained until it drops to 1NTU. A water level gauge is set in the circulating water tank, and water is replenished when the water level is lower than one-third of the height of the water tank. The circulating water outlet at the bottom of the circulating water tank is connected to the water filter 11 and the valve and then to the circulating water pump, which sends the circulating water from the nozzle into the ventilation channel 1 for spraying.
