Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of Treated sewage reusing boiler feedwater at
Reason equipment is described in further detail.According to following explanation and claims, the advantages of the utility model and feature will be more clear
Chu.It should be noted that attached drawing is using very simplified form and uses non-accurate ratio, only to conveniently, lucidly
Aid in illustrating the purpose of the utility model embodiment.
Embodiment 1
A kind of boiler feedwater treatment device of Treated sewage reusing of the utility model, structure diagram is as shown in Figure 1, described
The boiler feedwater treatment device of Treated sewage reusing is included through the sequentially connected fiber ball filter 1 of pipeline, ultrafiltration apparatus 3, anti-
Permeability apparatus 5 and ion-exchange demineralization device 6；Wherein, set between the fiber ball filter 1 and the ultrafiltration apparatus 3
First cartridge filter 2 sets the second cartridge filter 4 between the ultrafiltration apparatus 3 and the reverse osmosis unit 5, described
First cartridge filter 2 and second cartridge filter 4 can be filtered water, prevent in fine particles damage equipment
Membrane component improves the service life of the boiler feedwater treatment device of the Treated sewage reusing.
Specifically, the boiler feedwater treatment device further includes raw water box 7, fresh-water tank 8 and filtered water tank 9.The raw water
Case 7 is arranged between the fiber ball filter 1 and first cartridge filter 2.The fresh-water tank 8 is arranged on the reverse osmosis
Thoroughly between device 5 and the ion-exchange demineralization device 6.The filtered water tank 9 is arranged on the fresh-water tank 8 and the ion exchange
