Abstract
In a nozzle block, a fluid is uniformly sprayed over an entire housing inside through a spray nozzle with the rotation of a nozzle coupling part, thereby increasing a contact ratio of the fluid with contaminated gas and dramatically improving the purification efficiency. Additionally, a fluid for cleaning contaminated gas is allowed to flow opposite to a flow of contaminated gas, so that the contaminated gas and the fluid cancel out, and the contact ratio increases.
Claims6
A nozzle block, comprising:
- a support axis coupled to an inside of a housing, and having a water supply channel connected with a fluid supply part to transport a fluid supplied from the fluid supply part;
- a nozzle coupling part rotatably coupled to a lower end of the support axis, and having a fluid movement passage that is in communication with the water supply channel to transport the fluid;
- a plurality of spray nozzles mounted in the nozzle coupling part in a radial direction, and having a spray passage that is in communication with the fluid movement passage to transport the fluid, and a spray port to spray out the fluid in the spray passage;
- and
- an upper friction reducing member interposed between the support axis and the nozzle coupling part to fix a position of the nozzle coupling part while supporting the rotating nozzle coupling part,
- wherein a spray propulsive force is generated by the fluid sprayed through the spray nozzle so that the nozzle coupling part rotates in one direction or opposite direction.
