Full Text Introduction to the field of Invention
The Invention in one aspect relates to a louvre bracket assembly for air washers/humidification plants/cooling towers,
Prior art and drawbacks
The air washer is used in chemical plant/power plant/textile mills, for the purposes of humidification and air cooling applications. Air is allowed to pass through a chamber where water is being sprayed using spray nozzles. Air is getting cooled and humidified but carries water droplets due to its velocity. At the end of each stage, the gas and liquid need separation. Air washers are used for separation of such liquid and gas. Intake louvres are installed in such air washers and these are supported by louvre brackets. Similarly, in a cooling tower, intake-louvres are installed horizontally for intake of Air.
These louvres are supported by cutting slots on the cooling tower frame In case of timber or by grouting MS angle with the concrete wall and then aluminium cleats are riveted to this MS angle to provide support to the intake louvres.
The above methods of installation are very cumbersome and time consuming. They also need frequent maintenance and do not provide longer life usage of timber as intake louvres results cutting off trees and affecting the environment.
Objects of the Invention
It is thus an object of this Invention to propose an improved means by using which it is possible to solve maintenance problems and save the environment.
It is another object of this Invention to propose a support system, which is simple to install, maintenance free and long lasting.
It is a further object of this Invention to suggest novel bracket means for holding the louvres effectively.
It is yet another objects of this Invention to propose such a bracket means, which can be made to customers needs and can be easily installed.
It is a still further object of this Invention to propose such a bracket means which can be made cost effective and does not need expert supervision to install and can be easily installed by average skilled labours.
These and other objects of the Invention will be clear from the following paragraphs. Brief Statement of the Invention

Detailed description of the drawings
It will be seen from the figures of the drawings that the louvre bracket assembly 1 consists of a pair of brackets 2 of desired length, breadth and a plurality of louvres 3 of desired length and shaped. In the drawings, it will be seen that each louvre is mounted with its middle portion 3b into the inclined straight channel portion 2a of the bracket 2. This channel portion is integrally formed within the inner side 2b of the bracket by means of a pair of rigid raised portions 2c/2d.
The bracket can have as many numbers of such channel portions "2a" as there are numbers of louvres to be mounted one on each channel.
The angle of inclination of the channel decides the angle of inclination of the louvre. All the channels are uniformly inclined, though individual inclinations of the pair of bracket may vary if desired.
The top end 3a and lower end 3c of the louvre preferably have nearly horizontal inlet end 3aa, 3cc and outlet end respectively for air, though this may slightly vary.
For assembling the unit, one end of a plurality of louvres are first mounted on the inner side of the pair of brackets.
Where after, the inner side of the other bracket is used to hold the free ends of the louvres. For this, the brackets, the inner channels, the angles of inclinations distances between the adjacent inner channels, length and width of the channels vis va vis the mid portions of the louvres and other design construction aspects are carefully decided so that a perfect assembly is easily made.
For mounting the assembly to the walls of the desired unit, there is provided another channel 3d on the outer side of the bracket. This channel runs vertically through the entire outer length of the bracket and is open on both its top and bottom ends.
There is provided a metal plate 4 of suitable size matching the outer channel in cross-section.
This metal plate 4 can be of any desired length to hold a single or more such louvre bracket assembly.
Then outer channel portion of the bracket snugly slip through the metal plate end is held tightly thereto.
The final assembly thus comprises a pair of fixing plates 4a, 4b, a pair of brackets 4& A mounted on the holding plates and a plurality of louvres 2 held between the opposed inner sides of the brackets.
There can be more than one such pair of brackets held to the mounting plate as can be determined by the length of the plate.
The mounting plate is provided with suitable holes 4c, 4d to fix the mounting plates to the walls of the unit (not shown) using suitable screens (not shown) or other such fixing means.
In function, the air enters through the lower inner surface of the louvres, is deflected upwards by the inclined lower surfaces and is exited into the unit through the upper surface of the top end of the lower.
The louvres and the brackets can be made from any suitable material like metal sheets or synthetic plastics by well-known techniques.
This louvre bracket assembly is corrosion proof, erosion proof, cheap to assemble and requires almost no maintenance cost or supervision cost. If necessary a single louvre can be replaced in the rare instance of any damage or breakage.
