[0018] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0019] like Figs. 1-3 As shown, an environmental remediation spray device includes a water tank 3, a high-pressure spray host, a high-pressure spray nozzle 5, and a secondary filter 2. The water tank 3 is connected to the high-pressure spray host through a first pipe. The high-pressure spray host is provided with a second pipe, and a branch pipe is provided at the end of the second pipe away from the high-pressure spray host. The high-pressure spray nozzle 5 is installed on the branch pipe. The secondary filter 2 is installed at the water inlet 9 of the water tank 3.

[0020] It may also include a frame, with a water tank 3 located in the middle of the frame, a high-pressure spray host located at the bottom of the frame, and a water inlet 9 connected to the water tank 3 at the top of the frame. A secondary filter 2 is located at the top of the frame. Before entering the water tank 3, the water flows through the secondary filter 2 to filter impurities in the water and prevent blockage of the water tank 3 or the high-pressure spray nozzle 5. The water in the water tank 3 enters the high-pressure spray host through the first pipe. Under the action of the high-pressure spray host, the high-pressure water flows through the second pipe into the branch pipe and is finally sprayed out from the high-pressure spray nozzle 5 to achieve dust suppression.

[0021] The bottom of the frame body is provided with a water outlet 7, which is used as a second pipeline to extend out.

[0022] The water tank 3 is made of 304 stainless steel to ensure a long service life.

[0023] The bottom of the overall frame body can also be provided with universal wheels 8 to make the entire spraying device more mobile and capable of being used in different environments.

[0024] Compared with the traditional environmentally friendly watering vehicle, the spraying device provided in the utility model has better mobility and can be used in various scenes such as construction sites, narrow streets and construction rooftops. The high-pressure spraying nozzle 5 is arranged on the branch pipe, the number of high-pressure spraying nozzles 5 can be set to be multiple, and the branch pipe can be annular or have other specific shapes suitable for the environment to ensure the spraying effect. In addition, due to the low cost and good mobility of the device, a large number of devices can be arranged in a specific area, thereby having a larger working area than the traditional watering vehicle or spraying vehicle.

[0025] In some further embodiments, the water tank 3 is provided with a water inlet pipeline, the water inlet pipeline is provided with a water inlet electromagnetic valve 1, and the secondary filter 2 is arranged on the water inlet pipeline and located between the water inlet electromagnetic valve 1 and the water tank 3.

[0026] The secondary filter 2 is specifically located between the water inlet electromagnetic valve 1 and the water tank 3 to sufficiently filter impurities in the water,

[0027] In some further embodiments, the control system 6 is further included; the water tank 3 is provided with a liquid level switch, the liquid level switch is in electrical signal connection with the control system 6, and the water inlet electromagnetic valve 1 is in electrical signal connection with the control system 6.

[0028] The water tank 3 is also provided with a liquid level switch to detect the water storage state in the water tank 3. Specifically, when the water in the water tank 3 reaches the low liquid level switch, the low liquid level switch feeds back a signal to the control system 6, and the control system 6 controls the water inlet electromagnetic valve 1 to start water replenishment after receiving the signal. When the water in the water tank 3 reaches the high liquid level switch, the high liquid level switch feeds back a signal to the control system 6, and the control system 6 controls the water inlet electromagnetic valve 1 to stop water replenishment after receiving the signal, thereby ensuring that the water in the water tank 3 is sufficient at all times and ensuring the continuity of spraying.

[0029] For example, the liquid level switch can be a float type liquid level switch or an electrode type liquid level switch.

[0030] In some further embodiments, the filter core of the secondary filter 2 is a PP cotton filter core.

[0031] The filter core of the secondary filter 2 in the embodiment is preferably a PP cotton filter core, and the filtering precision can reach 5 microns, which can effectively prevent the high-pressure spraying nozzle 5 from being blocked due to water quality factors.

[0032] In some further embodiments, the high-pressure spray host comprises a high-pressure plunger pump 4, and a check valve is arranged on the outlet of the high-pressure plunger pump 4.

[0033] For example, the high-pressure spray host comprises a high-pressure plunger pump 4, the pressure of which is 60-120 bar and can be adjusted according to actual conditions, the flow rate is 11-50 L / min, the voltage is 380 v, the frequency is 50 Hz, and the rotating speed is 1450 RPM. Under the action of the control system 6, the high-pressure spray host can be automatically operated.

[0034] In addition, in order to ensure that the entire device does not drip water during operation or shutdown, a check valve is arranged on the high-pressure plunger pump 4.

[0035] The output flow rate of the high-pressure spray host in the embodiment can be infinitely adjusted within the range of 100 kg / h-2600 kg / h, and the number of high-pressure spray nozzles 5 corresponding to the flow rate range can be configured arbitrarily.

[0036] In some further embodiments, the first pipe and the second pipe are high-pressure stainless steel pipes.

[0037] The first pipe and the second pipe are high-pressure stainless steel pipes. For example, they can be Ф22 mm standard specification with a wall thickness of 1.5 mm and a pressure resistance of 250 bar, or Ф9.52 mm standard specification with a wall thickness of 0.8 mm and a pressure resistance of 220 bar.

[0038] In some further embodiments, the branch pipe is a ring-shaped branch pipe.

[0039] The ring-shaped branch pipe can increase the effective spray range to ensure the coverage range of the spray.

[0040] The high-pressure spray nozzle 5 can be connected to the ring-shaped branch pipe in an external thread manner, and the connection material is brass. The working pressure of the high-pressure spray nozzle 5 is 2-80 bar. The high-pressure spray nozzle 5 can generate 5 billion droplets per second, and the droplet diameter is 5-15 μm. Through the high-pressure spray host, water is split into a negative-electricity water droplet surface layer and a positive-electricity inner layer by the high-pressure spray nozzle 5, the negative-electricity water droplet surface layer combines with atoms or molecules in the air to form negative ions, and the heavy water droplet inner layer sinks under the action of gravity, so that a large number of negative ions can be obtained in the air. The water mist particles floating in the air can also absorb dust particles, playing a role of spray dust suppression. The mist generated by the high-pressure spray nozzle 5 can reach 3-5 m in length and spray within a range of 90° around.

[0041] The urban street road lamp pole is widely distributed, has large density and fixed position, and the characteristics give the spraying device a supporting device, and the spraying device is provided with installation conditions, effectively controls urban dust pollution, and reduces the content of PM2.5 and PM10 in the air.

[0042] The control screen is further included, and manual or automatic control can be switched through the control screen, that is, a timing on-off machine, a time cycle mode and the like can be set.

[0043] The utility model application scene is more wide, such as small street with street lamp, high building roof and the like can be set as long as having the attachment point, the device has long service life, and the processing effect is good, and the operation is simple, and the full automatic operation does not need the special full-time manual operation. In addition, it can save energy and reduce discharge, and reduce cost and increase benefit, and has more obvious economic benefit and social benefit.

[0044] Obviously, the above embodiments are only examples for clearly illustrating, and are not limited to the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted.
