Description

Technical Field

[0001] The invention relates to the technical field of environmental protection and energy saving, and in particular to a dust reduction method of a dust suppression water sprinkling membrane assembly. Background Art

[0002] The yard is an essential infrastructure for providing public services such as transit, storage, transportation and distribution. However, for many years, the dust problem in the yard has been the main environmental problem that has troubled local governments and operating units. With the country's emphasis on environmental protection, environmental laws and regulations have further strengthened the requirements for the control of dust pollution, and environmental protection departments at all levels have increased their efforts to rectify the pollution problems of open-air yards. At present, the main means of dealing with dust pollution in the yard are surface covering, water sprinkling and setting up windbreaks. Surface covering is a common dust reduction technology. By laying a layer of dust-proof film on the yard, the pile is effectively isolated from the external environment, thereby preventing the dust on the pile from floating into the air; water sprinkling is a common dust reduction technology. Water mist is sprayed through the spray pipe and nozzle, and the dust collides and condenses with the water mist. When the water mist contains more dust and the condensed particles are larger, it will settle, thereby playing a role in dust reduction; the windbreak is to surround the yard with steel plates with a height of no more than 6m to form a high wall, thereby blocking the wind, so that the pile in the yard is no longer affected by the wind, thereby achieving the effect of dust suppression.

[0003] Although dust suppression is effective when the surface is covered with a dust-proof film, it also hinders the air permeability of the pile, which can easily cause adverse effects on some piles that require air permeability; when a water sprinkler dust suppression device is used, due to strong winds, the water mist is easily blown away by the wind and cannot come into contact with the dust, so it cannot effectively suppress dust in a windy environment, and spraying a large amount of water will cause a waste of water resources, and dust will still escape during the water spraying and dust suppression process to pollute the environment; although a windproof net can effectively block strong winds, it is inconvenient to install and requires extremely high installation technology to ensure its safety. Summary of the invention

[0004] The object of the present invention is to provide a dust reduction method of a dust suppression watering membrane assembly which can allow the pile to ventilate in a windless or light wind environment, can quickly seal the pile when dust is caused by strong winds to prevent the pile from being affected by the strong winds, and can also quantitatively humidify the pile.

[0030] A plurality of fourth air holes 41 are evenly distributed on the water absorbing layer 4, and a row of mounting holes 42 is arranged between each two adjacent rows of fourth air holes 41. The bottom of the air-filled layer 3 is compositely bonded to the top of the water absorbing layer 4, and the third air holes 31 are aligned one by one with the fourth air holes 41. Each row of airbag holes 34 is aligned with a row of mounting holes 42. A fifth air hole 51 is evenly distributed on the sensing layer 5, and a row of drainage grooves 52 is arranged on the sensing layer 5 between each two adjacent rows of fifth air holes 51, and a water outlet 53 is arranged in each row of drainage grooves 52. The dust sensor includes: an infrared light emitting diode 54 and a phototransistor 55. A plurality of pairs of sensor holes are arranged at intervals on the sensing layer 5, and an infrared light emitting diode is arranged in each pair of sensor holes. 54 and phototransistor 55, the infrared light emitting diode 54 and phototransistor 55 in each pair of sensor holes are arranged opposite to each other, the infrared light emitting diode 54 and phototransistor 55 are connected to the industrial computer, and there are correspondingly a plurality of fifth air holes 51 between each pair of infrared light emitting diodes 54 and phototransistor 55, the optical axes of the infrared light emitting diodes 54 and phototransistor 55 in each pair of sensor holes are intersected, and the fifth air holes 51 corresponding to each pair of sensor holes are in the optical axis intersection area, when dust passes through the fifth air holes 51 in the optical axis intersection area, the dust will reflect the infrared light in the area, and the phototransistor 55 can detect the reflected light, and the phototransistor 55 converts the light intensity of the detected reflected light into The light intensity signal is transmitted to the industrial computer, and the industrial computer determines the dust concentration according to the size of the light intensity signal.

The water absorbing layer 4 is compositely bonded to the sensing layer 5, and the fourth air hole 41 is aligned with the fifth air hole 51 one by one. After the water absorbing layer 4 is compositely bonded to the sensing layer 5, the water absorbing layer 4 cooperates with the sealing soft board 56 to seal the infrared light emitting diode 54 and the phototransistor 55 in the sensor hole. The mounting holes 42 on the water absorbing layer 4 are aligned with the drainage groove 52 one by one. A plurality of pressure-bearing drainage parts are arranged in the relatively aligned mounting holes 42 and the drainage groove 52, and each pressure-bearing drainage part is aligned with The pressure-receiving drainage member is a sponge 43, and the water supply mechanism is a water pressure regulating valve 44. A water pipe 45 is connected to each sponge 43. A water supply branch pipe 46 extending from the water-absorbing layer 4 is arranged in the mounting hole 42. The water supply branch pipe 46 in each column of mounting holes 42 is connected to a main water pipe 47. The main water pipe 47 is connected to a water source through the water pressure regulating valve 44. Each sponge 43 in each column of mounting holes 42 is connected to the water supply branch pipe 46 in the mounting hole 42 through a water pipe 45 connected to each sponge 43. A valve groove is arranged in each water pipe 45. Each air bag 32 in each column of air bag holes 34 abuts against each sponge 43 in the corresponding mounting hole 42. The valve groove will not affect the water in the water pipe 45 from being input into the sponge 43.However, the principle of anti-backflow of the heart valve is used to prevent the water in the sponge 43 from flowing back into the water pipe 45 after the sponge 43 is squeezed.

[0031] After the air permeable layer 1, the air filling layer 3, the water absorbing layer 4 and the sensor layer 5 are compounded and adhered together in sequence, two positioning holes 6 penetrating the air permeable layer 1, the air filling layer 3, the water absorbing layer 4 and the sensor layer 5 are opened on the dust suppression and watering membrane assembly.

[0032] Its working principle is as follows: S1. Spread the watering membrane assembly on the pile, and then fix the dust suppression watering membrane assembly through the positioning hole 6. A plurality of joint connectors 26 are arranged at intervals on the telescopic layer 2. Each joint connector 26 is connected to a hydraulic cylinder 24. The inflation branches 35 on the inflation layer 3 are connected to a main air pipe 36, and then the main air pipe 36 is connected to the air source through the air pressure regulating valve 33. The water supply branches 46 on the water absorption layer 4 are connected to a main water pipe 47, and then the main water pipe 47 is connected to the water source through the water pressure regulating valve 44, and the hydraulic cylinder 24. The air pressure regulating valve 33, the water pressure regulating valve 44, the infrared light emitting diode 54 and the phototransistor 55 are connected to the industrial computer; then two levels of dust concentration are set in the industrial computer, one level is a slight dust concentration, and the other level is a rated dust concentration. The rated dust concentration is the emission standard specified in the "Comprehensive Atmospheric Emission Standard" GB16297-1996, and the slight dust concentration is half of the rated dust concentration; the second air holes 23 on the telescopic layer 2 are aligned one by one with the first air holes 13 on the air permeable layer 1, so that the stacking material can obtain a better ventilation effect;

[0033] S2. When the wind blows in the yard, the stockpiles will raise dust to the outside through the relatively aligned air holes, and the infrared light emitting diodes 54 and phototransistors 55 in each pair of sensor holes can monitor the dust concentration in the corresponding fifth air hole 51. When the monitored dust concentration reaches the slight dust concentration value, the industrial computer will control the hydraulic cylinder 24 to synchronously drive the telescopic layer 2 to move on the air permeable layer 1, so that the second air permeable layer 23 on the telescopic layer 2 and the first air permeable holes 13 on the air permeable layer 1 are offset by half, so that all the first air permeable holes 13 are half blocked, reducing the impact of the wind on the stockpiles;

[0034] When the monitored dust concentration reaches the rated value, the industrial computer will control the hydraulic cylinder 24 to synchronously drive the telescopic layer 2 to move on the breathable layer 1, so that the second air hole 23 on the telescopic layer 2 is completely misaligned with the first air hole 13 on the breathable layer 1, so that the telescopic layer 2 blocks the first air hole 13, so that the pile can be prevented from raising dust to the outside. Then the industrial computer controls the water pressure regulating valve 44 to open, and the water in the water source is transported to each sponge 43. When all sponges 43 absorb a certain amount of water, the industrial computer controls the water pressure regulating valve 44 to close, and the industrial computer controls the air pressure regulating valve 33 to open, and the compressed air in the air source is transported to each air bag 32. After the air bag 32 expands, it squeezes the sponge 43 downward, and the water in the sponge 43 is squeezed out, and then all flows to the pile through the water outlet 53 to wet the surface of the pile.

[0035] S3, the airbag 32 is deflated and restored, and the industrial computer controls the hydraulic cylinder 24 to drive the telescopic layer 2 to reset. When the limiting piece 25 on the telescopic layer 2 abuts against the limiting slot 14 of the breathable layer 1, the telescopic layer 2 is reset, and the second air holes 23 on the telescopic layer 2 are aligned one by one with the first air holes 13 on the breathable layer 1. At this time, the wet stockpile is no longer affected by the wind and dust is raised.

[0036] When the volume of the pile is too large, multiple dust suppression and watering membrane assemblies can be spliced ​​together to form a larger dust suppression and watering membrane assembly, which is then spread around the pile. The splicing method is to connect the positioning holes 6 between two adjacent dust suppression and watering membrane assemblies with straps or hinges. In this way, multiple dust suppression and watering membrane assemblies will be in different orientations, and the components in each dust suppression and watering membrane assembly will be connected to an industrial computer. The working logic of each dust suppression and watering membrane assembly is separately set in the industrial computer. When the wind blows in one direction, the pile on the windward side is prone to dust. The infrared light emitting diode 54 and the phototransistor 55 in the dust suppression and watering membrane assembly on this side can easily detect a higher dust concentration. When the dust concentration at this location reaches the rated value, the industrial computer will control the dust suppression and watering membrane assembly on this side to start sealing, humidifying, and dust reduction work, and the dust suppression and watering membrane assemblies on other sides will not participate in the work.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
