The construction of environmental protection tower crane spray mechanism comprises a base, a tower crane erected on the base and a balance arm and a lifting arm arranged horizontally on the tower crane. The tower crane and the lifting arm are arranged with a vertical water supply pipe and a horizontal water supply pipe, and the lifting arm is arranged with a plurality of spray heads connected with the horizontal water supply pipe. The vertical water supply pipe and the horizontal water supply pipe are connected through a rotary joint. One side of the base is also provided with a dewatering well, which is provided with a pipe connected with a vertical water supply pipe; When the mechanical tower crane spray machine is used, the groundwater extracted from the precipitation well is sprayed out through the spray head to form a flying water mist, which can effectively adsorb the dust particles and impurities in the air, and play the role of dust reduction. At the same time, after a period of high altitude spray, the ground will form a moist state, which can effectively suppress the dust.
Technical principle of tower crane spray dust removal misting system:
The fine water mist sprayed by the spray misting system is continuous and uniform, the diameter of the fog particles is small, usually 1-50 microns, the speed of the fog particles is high, the density is large, and has many special properties, which can quickly absorb the surrounding heat, and make the dust absorb humidification and condense in the gasification state, so as to achieve the purpose of cooling and dust removal.
"High-altitude spray" can not only absorb dust in the air, but also cool down. The temperature of the site in summer is as high as 40 degrees, and it is impossible to work normally manually. After adopting this technology, the average temperature of the site can be reduced by 5-8 degrees. In the maintenance of construction projects, "high-altitude spraying" replaces manual timing sprinkling, reduces human input, avoids interference with other types of work, and can save about 40 tons of water per month.
High-altitude spray misting system, is the use of groundwater, the water in the fire pool, the formation of flying water mist at a high altitude, so that the construction site 24 hours uninterrupted underground "drizzle", adsorption of dust particles and impurities in the air, play a role in dust removal. After spraying at high altitude for a period of time, it can moisten the ground and effectively prevent dust from being raised again. In the hot and high temperature season, it can also cool down outdoor workers and bring great convenience to dust work.
Automatic site tower crane spray includes reservoir, water pump integrated host, vertical water supply pipe connected vertically on the tower crane and horizontal water supply pipe connected horizontally on the tower crane arm, the vertical water supply pipe and horizontal water supply pipe are connected through the universal rotary joint, the inlet end is connected to the reservoir, after the controller of the main engine starts the pump, the misting system can start spraying work. The horizontal arm of the tower crane is always at the highest point of the construction site, and the sprinkler misting system sprays water in an all-directional, zero-dead corner mist within the rotating range of the tower crane. The water shoots flying mist through the nozzle, which can effectively adsorb dust particles and impurities in the air, and control the dust from the construction site from spreading outwards, playing the role of dust lowering. Meanwhile, after spraying at high altitude for a period of time, the ground will form a moist state. It can effectively suppress the dust to rise again.
In the high-altitude spray dust removal misting system, the main riser is attached to the inner side of the tower crane body, and the top transverse head of the riser is installed at the bottom of the lifting arm, and several nozzles are set. The dust removal area of the spray mist covers a wide working surface within the rotating radius of the tower crane by relying on the rotation of the tower crane, and the dust removal can be enhanced by spraying water on the key parts of the dust in the air. Especially in the process of excavation, the use of high-altitude spray dust removal can effectively improve the dust removal effect and return the city's clean blue sky. The design of the misting system is simple, and the effect of spray dust removal is realized through strict construction quality control.
Automatic tower crane spray machine features:
1, our company's control host can accept the data collected by the PM10 dust detector, can automatically open or close the dust removal misting system. At the same time, it can also realize the opening and stopping of the remote control control misting system, control the size of the water mist and the amount of water, so that the operator and the tower crane driver, the ground concrete wet water maintenance, and the site fire protection.
2. At the same time, it has three functions of site dust removal, site concrete wet water maintenance and site fire protection.
3, the misting system uses the tower crane 360 rotation, can fully cover the site, from the air to the ground three-dimensional spray, thereby inhibiting the drift and diffusion of airborne dust.
4, once the safety net of the site is on fire, you can immediately open the fire mode of the misting system, increase the amount of water sprayed, you can pour the fire seedlings in the first time, and quickly control the fire.
Automatic tower crane spray machine product installation:
1, it must be installed by workers with professional skills under the guidance of the company's technical personnel.
2, the misting system of water pump integrated host, nozzle, universal rotary joint, water pipe specifications and models must be strictly calculated in accordance with the height of the tower crane and site layout, must be accurate selection and matching.
3. Before installation, the installation plan must be discussed with the construction side and the tower crane operator to ensure the safety of the site.
