Problems solved by technology

This process design only considers the workflow of soil pretreatment, and does not consider the treatment of soil dust generated during the process of soil entering the hopper and crushing device. A large number of polluted soil dust particles will inevitably affect the environment of the construction site, and will also pose a hazard to the physical and mental health of construction workers

Embodiment 1

[0018] The dust particle concentration in a factory workshop is 100mg / m 3 , it is expected that the concentration of dust particles after dust fall will be 20mg / m 3 , The dust reduction rate can reach 80%.

[0019] 1) The aperture of atomizing nozzle 14 is 1.2mm, which requires a spray water pressure of 6MPa;

[0020] 2) The aperture of atomizing nozzle 14 is 1.5mm, which requires a spray water pressure of 4MPa;

[0021] 3) The water consumption of the atomizing nozzle 14 with an aperture of 1.2 mm is 5.0 L / min, and the water consumption of the atomizing nozzle 14 with an aperture of 1.5 mm is 6.5 L / min.

[0022] Although the atomizing nozzle 14 with an aperture of 1.5mm requires low pressure, the water consumption per unit time is 1.5L / min more for each atomizing nozzle 14 with an aperture of 1.5mm, consuming 25% more water resources.

[0023] (2) If the high-pressure water pump 2 can provide the amount of water to the spray system, each atomizing nozzle 14 has only 3L / min...

Embodiment 2

[0030] If the dust concentration is set to 5g / min and the roadway wind speed is 0.5m / s, the dust data concentration of the atomizing nozzle at the front and rear sections of the roadway spraying section at different pressures can be measured, and the dust drop rate at different pressures can be obtained according to the dust concentration efficiency data.

[0031] (1) For the same type of atomizing nozzle 14 and dust with a certain particle size distribution, the spray dust suppression efficiency under the wind speed of 0.5m / s increases with the increase of spray pressure, from 2MPa to 8MPa, and the dust dust suppression efficiency improves 21.32%, but when the atomization pressure increased from 8MPa to 10MPa, the dust reduction efficiency only increased by 1.79%.

[0032] When the spray pressure reaches a certain value, continue to increase the spray pressure, the improvement of the dust reduction efficiency is not obvious. Spray dust reduction is mainly carried out through ...

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-pressure spray dust removal system applied to the soil restoration process. Background technique [0002] In soil site remediation projects, with the improvement of the mechanization and automation level of remediation equipment, the intensity of remediation work and the amount of dust generated have increased, and the content of respirable dust with a particle size of less than 7 μm has also increased significantly. However, dust in this particle size range is the most harmful, manifested in: (1) reducing the visibility of operations; (2) shortening the safety and service life of mechanical equipment; (3) increasing the incidence of occupational diseases, especially pneumoconiosis. At the same time, the launch of the national PM2.5 standard shows that the country attaches great importance to dust pollution and smog. [0003] The complete set of...
