Among the figure: 1-cross perforation formula water distributor (water distributor), 2-central dividing plate (division plate), the female pipe tubular type " a backwash water sparger " of 3-, 4-deoxygenator tank body, 5-packing layer back up pad, the former water water inlet pipe of 6-, 7-backwash water rising pipe, 8-water outlet pressure solenoid, 9-inlet gage arm, 10-raw water flow table, 11-backwash water rate of flow meter, the 12-sampling valve, mother's pipe of the female pipe tubular type " a backwash water sparger " of 13-, the arm of the female pipe tubular type " a backwash water sparger " of 14-; 1 ', 2 ', 3 ', 4 ', 5 ', 6 ', 7 ', 8 ', 9 ', 10 ', 11 ', 12 '-cross perforation formula water distributor water vent, 1 ", 2 ", 3 ", 4 ", 5 ", 6 ", 7 ", 8 ", 9 " the arm posticums of a female pipe tubular type " a backwash water sparger "; The former water water intaking valve of V1-, V2-backwash water water intaking valve, half and half backwash water intaking valve about V3, V5-, half and half secondary backwash water intaking valve about V4, V6-, V7-backwash wash water valve, V8-advances the water tank water valve, and V9-is just washing the blowdown water valve, V10, V11-wash water valve.
The utility model normal temperature sponge iron deoxygenator by deoxygenator tank body 4, packing layer back up pad 5, inlet and outlet pipe lines and on valve V1～V11 etc. form.A metal central dividing plate 2 is welded between 80～120mm place and the deoxygenator tank body 4 under the oxygen scavenger packing layer surface in the bottom of the utility model in deoxygenator, and tank body 4 bottoms evenly are divided into two independent parts.Below the former water water inlet pipe 6 in deoxygenator tank body 4 tops, be equipped with the cross perforation formula water distributor 1 of energy water distribution uniformity.Water distributor 1 horizontal positioned, the water vent on the water distributor 1 be positioned at its below, have between each water vent certain intervals and with plummet in angle of 45 degrees, the angle between adjacent two water vents be 90 the degree.The both sides of 700～800mm place central dividing plate 2 respectively are equipped with one by one by mother and manage 13 and mother's pipe tubular type " a backwash water sparger " 3 of constituting of arm 14 below the oxygen scavenger top layer of oxygen scavenger packing layer in described deoxygenator, be connected with 3 arms 14 on each female pipe 13, all horizontal positioned.Posticum direction on each arm 14 and in line, has certain intervals between each posticum vertically downward.Packing layer back up pad 5 is a round-hole punched plate in the described deoxygenator, and the round-hole punched plate aperture is 12～15mm, the deoxygenation packing layer of being made up of the high reactivity sponge iron deoxidizing agent of the pebbles of diameter 16～25mm and size fractionated on the packing layer back up pad 5.
The working process of the utility model normal temperature sponge iron deoxygenator is as follows:
During normal the operation, the former water that need carry out deoxygenation carries out water distribution through the V1 valve by deoxygenator top cross perforation formula water distributor 1, makes former water pass through the sponge iron deoxidizing agent packing layer uniformly, dissolved oxygen and sponge iron in the former water fully react, thereby the dissolved oxygen in the former water is reacted away.Water after the processing enters water tank through V4, V6 and V8 valve.
After deoxygenator used for some time, dissolved oxygen and sponge iron in the water reacted, the Fe of generation (OH)
3Flocculent precipitate is adsorbed, holds back by the sponge iron packing layer, and causes the deoxygenator resistance to increase, and need carry out backwash this moment.Earlier with all valve closess, open V2, V7 valve then during backwash, opened V3, V5 valve more respectively each 3～5 minutes; After finishing, close V3, V5 valve, open V4, V6 valve more respectively, till the sewer of backwash was clear, just washed this moment.When just washing, earlier with all valve closess; At first open V1, V4, V6 and V9 valve,, then go out water hardness and oxygen level all must comply with the national standard requirements (boiler feed water is like this) if backwash water uses is service water, just close and just washing wash water valve V9, open the V8 valve then, make deaerated water enter water tank, throw the people and normally move; If what backwash water was used is soft water, the oxygen level of then only measuring water outlet meets national standard (or required standard) but normal operation input just.
The utlity model has following advantage:
1, described cold sponge iron deoxidising device has been exempted the thermal energy consumption of traditional deoxygenation, has reduced the production run expense. Compare the economic benefit of corresponding increase more than 15% with the thermal de-aeration mode.
