Spray apparatus used on building site and control method thereof

Abstract

The invention relates to a spray apparatus used on a building site, which solves the deficiencies of prior art technology. The technical method involves: the apparatus includes a fog gun water inlet pipeline, a fog gun, a fog gun control unit, a fog gun angular motor, a fog gun angular frequency converter, a fog gun water inlet pipeline pressure transducer, a fog gun water inlet pipeline flow sensor, a booster pump, a booster pump frequency transducer, a booster pump outlet pressure sensor, a water inlet pipeline solenoid valve and a manual control button. The fog gun control unit is in electrical connection with the fog gun angular motor via the fog gun angular frequency transducer, and the fog gun water inlet pipeline is communicated with the fog gun via the booster pump, and the fog gun water inlet pipeline pressure sensor, the water inlet pipeline solenoid valve and the fog gun water inlet pipeline flow sensor are all configured on the fog gun water inlet pipeline. The fog gun water inlet pressure sensor, the water inlet pipeline solenoid and the fog gun water inlet pipeline flow sensor and the fog gun control unit are connected. The manual control button is also connected to the fog gun control unit. The fog gun control unit is in electrical connection with the booster pump via the booster pump frequency transducer.

Description

technical field [0001] The invention relates to an environment monitoring and improving system and a control method thereof, in particular to a construction site spray device and a control method thereof. technical background [0002] In the prior art, a large amount of water spray devices are generally installed on the fixed buildings of the construction site or on the surrounding ground, and the spray water of the water spray devices is used to reduce and remove dust. However, this method has poor dust removal effect, especially for PM2.5, which basically has no sedimentation effect. Secondly, due to water evaporation, frequent water spraying is required, which increases costs and causes secondary pollution of water. [0003] The droplet size of the traditional water spray dust suppression is between 50 μm and 300 μm. Compared with the dust of PM10 and below, which has a very long air time, the air time of the droplets is very short, and the chance of contacting and conden...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to solve the common construction site environmental monitoring devices in the market with simple system design and low degree of automation integration in the prior art. Line control, in this case, there are many wiring, complex wiring, few analog signals, few functions, simple protection functions, no information interaction, low intelligence, which is far from meeting the needs of modern construction sites, especially green buildings. The problem of the construction needs of the construction site, providing a spray device and its control method for the construction site
