Description
WATER DRAIN STRUCTURE FOR BLOWER
FIELD OF THE INVENTION
pool] The invention relates to a water drainage system for a blower.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
pool] The invention relates to a water drainage system for a blower.
BACKGROUND OF THE INVENTION
[0002] Furnace industry has minimized the use of fuel resources, and thermal efficiency of typical furnaces has achieved to 90%. With the improvement of the thermal efficiency, the amount of liquids or humidity in exhaust gas increase, and condensed water is released from the exhaust gas. Thus, the more condensed water formed is, the higher efficiency the furnace has. Also, the amount of the condensed water is dependent on the relative humidity of the air used in the reaction of combustion. Condensed water in the air exhausting device, particularly in the shell of the blower, is required to be output, not only because it would otherwise result in problems affecting the operating performance of the furnace, for example, condensed water accumulated in the shell of the blower would decrease the performance of the air, which in turn extinguish the burning furnace;
but also because the condensed water is acid, which is a main factor that should be considered in selecting materials of furnace.
, [0003] To output the accumulated condensed water, a typical method is that the scroll casing of a blower of a furnace is provide with a drainage outlet connected with a joint of a drainage pipe, however, condensed water can only be output when the blower is powered off. When the blower is energized, air flow produce a suction when passing the opening of the joint of the drainage pipe due to the Venturi effect, which prevents the condensed water from being output from the drainage pipe. Another typical method is that: drainage channels are designed on a joint between the wind pipe and the exhaust pipe. However, the joint has complicated structure, high production cost, inconvenient installation, and the drainage effect is not so good.
