如果加热爐爐門前面有層“水幕”,就可以减少从爐子里輻射出来的热,并且降低車間空气中的一氧化碳气体(有毒)的含量。在爐門前面安裝一套如圖所示的裝置,就能形成“水幕”。圖中1是进水管,跟自来水管接通;2是从进水管流来的水;3是一个水槽,它的外沿往外弯;4是接水器;5是排水管,跟下水道接通。水槽里的水滿了,就会往外流;这样就形成了一層透明的“水幕”,把爐門遮住。 If there is a layer of “water curtain” in front of the furnace door, it can reduce the heat radiated from the furnace and reduce the amount of carbon monoxide gas (toxic) in the workshop air. In front of the door to install a set of devices as shown in the figure, you can form a “water curtain.” 1 is the inlet pipe, connected with the water pipe; 2 is the water from the inlet pipe; 3 is a sink, the outer edge of the bend; 4 is the water receiver; 5 is the drain pipe, connected with the sewer . When the water in the sink is full, it will flow outward; thus forming a transparent “water curtain” covering the door.
