Description

Rotary spray unit using a fan {a mobile spray unit using fan}

The present invention relates to a nebulizer, and more particularly, by supplying air to the body of water sprayed from the nozzle tube, the sprayed water is sprayed in the form of a spray by the air to form a mist film in a predetermined space through which scattering dust and the like It relates to a rotary spray device using a fan to be able to suppress.

In general, when a fire occurs, smoke is generated together with a flame, and the smoke is diffused to an adjacent area through airflow. Flames can be extinguished through a fire extinguisher at such a fire site, but the smoke is left as it is, causing secondary damage when spreading to adjacent areas.

In addition, when the tunnel is excavated to build a road, etc., the blasting work is performed. When the blasting work is performed inside the tunnel, harmful gases such as dust or dust due to the explosives are generated. The gas is completely discharged to the outside and then other work is performed. Accordingly, there was a problem that the work time is unnecessarily delayed because the worker cannot proceed with other work continuously after the blasting work.

In order to solve this problem, the conventional method of installing a blower pipe inside a tunnel and discharging harmful gas generated at the same time as the blasting work to the outside through the blower pipe has been proposed.

However, when the harmful gas is discharged to the outside through the blower pipe as described above, the external structure or the external environment is greatly polluted, causing civil complaints and other problems.

In order to solve the pollution problem in the above manner, a device has been proposed to filter the dust by providing a filter to the blower pipe and then discharge the filtered air to the outside. This is possible in a very short section of the tunnel, but the length of the tunnel In the long case, as the length of the blower and the filtering device of the corresponding length is required, there has been a problem in that the work and the installation cost greatly increase due to the connection of the blower or the installation of the filtering device.

In addition, a technology for removing harmful gas particles through water sprayed through the nozzle has been proposed by installing a high pressure pipe along the circumference of the tunnel and installing a plurality of nozzles in the high pressure pipe.

However, since the high pressure pipe is fixedly installed on the inner wall of the tunnel, the cost is greatly increased when the high pressure pipe is to be installed as the tunnel proceeds.

Recently, the Republic of Korea Patent Registration No. 10-0812570 "scattering device for scattering dust removal applied in the blasting construction of the tunnel" has been presented.

It is invented by the inventor of the present invention, comprising: a frame mounted with a spray pump pumped by a motor and having wheels movable along the ground or rail; A nozzle body provided on the frame and connected to a water supply part of the spray pump and a hose to spray water through a pumping operation; It is provided on the frame to provide a nozzle flow means for flowing the nozzle tube to greatly expand the injection range of water.

However, the nozzle body is a nozzle flow means to inject water while reciprocating the left and right and the water launched at this time hits the ceiling surface of the tunnel to form a screen membrane inside the tunnel is difficult to transport and thus limited to tunnel work accordingly There has been a problem of being used.

In addition, when the lining is cured by placing concrete on the inner wall of the tunnel after the tunnel construction, water is sprayed to the lining to cool the heat generated while the lining is cured so that cracks do not occur. Work by spraying.

However, in the above case, there has been a problem in that the working time is delayed and the cost is increased as the vehicle is moved to the lining wall.
