SMALL BUSINESS INNOVATION RESEARCH: "Catalytic Air Cleaner"

化学污染的空气将在整体热交换器和反应器中通过催化氧化进行净化和/或解毒。这种双螺旋装置是用催化剂将两条金属涂层缠绕在一起制成的。一条螺旋通道通向螺旋的核心，另一条通道通向螺旋的核心。电阻加热器在螺旋的核心处提供能量。流出的空气通过螺旋管壁将这些热量传递给流入的空气，从而将指定核心温度所需的热输入降至最低。由于热交换，堆芯温升可能是现有空气中温升的数倍。研究的目的是考察典型污染物的传热率、催化反应速率和热损失速率，并确定典型污染物所需的表面面积、热输入、核心温度等。

Chemically contaminated air is to be purified and/or detoxified by catalytic oxidation in an integral heat exchanger and reactor. This device of a double spiral is made by winding together two strips of metal coatewd with a catalyst. One spiral passage leads into the core of the spiral and the other passage leads out. An electrical-resistance heater supplies energy at the core of the spiral. The outflowing air transfers this heat to the inflowing air through the walls of the spiral, thus minimizing the required heat input for a specified core-temperature. Owing to the heat exchange the core-temperature-elevation may be many times the temperature-elevation in the existing air. The objective of the research is to investigate the rates of heat transfer, catalytic reaction and heat loss, and to determine the necessary surface are, apacing, heat input, core temperature, etc., for representative contaminants.
