Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail below by means of specific embodiments and with reference to the attached drawings, and the technical solutions not described in detail in the present invention can refer to the background art or the prior art.
Fig. 1-4 show the utility model discloses a structural schematic diagram, wherein fig. 1 is the structure chart when taking place the overflow, this desulfurizing tower overflow arrangement, including the immersion fluid pipe 2 that soaks the thick liquid in the desulfurizing tower 1, immersion fluid pipe 2 stretches out 1 outer joint in desulfurizing tower through return bend 3 and has outlet pipe 4, outlet pipe 4 is connected with thick liquid collection device 5, immersion fluid pipe 2, return bend 3 and outlet pipe 4 become the setting of U type, 2 mouth of pipe positions of immersion fluid pipe are higher than 4 mouth of pipe positions of outlet pipe, are located the minimum thick liquid level in desulfurizing tower 1 and are higher than 2 mouth of pipe positions of immersion fluid pipe, 2 pipe walls of immersion fluid pipe are opened there is a through-hole 6.
When the thick liquid level surpassed minimum thick liquid level and when surpassing return bend 3, overflow arrangement passes through under the effect of liquid level, and the thick liquid in the desulfurizing tower is automatic from immersion tube 2 through outlet pipe 4 dip thick liquid collection device 5, but because siphonage's existence, when the thick liquid level reachs minimum thick liquid level, the thick liquid does not stop flowing, will soak 2 mouths of pipe until the thick liquid level, the utility model discloses the through-hole that increases can guarantee when the through-hole is reachd to the liquid level, does not take place siphonage.
