Abstract

The utility model is a rotary diaphragma deaerator which relates to the art of deoxidation of the water for a boiler. It mainly solves the technical problems in the prior art that the effect of deaeration is bad, the energy consumption is high and the maintenance is difficult. To solve the technical problems above, the utility model has the following technical characteristics: an intake(7) and an outtake(15) are equipped respectively at the left side and at the right side of the water chamber(6), a steam pipe(21) and a steam nozzle(13) are equipped in the bottom steam chamber(19) of the deaerator, etc. This deaerator is mainly used in the deaeration of the water for a boiler to reduce the erosion of related apparatus by water.

Description

Membrane deaerator

Technical field

The utility model relates to the water treatment facilities of boiler feedwater, relates in particular to a kind of membrane deaerator.

Background technology

Boiler supply water deaerating is the especially necessary technology means of station boiler mitigate corrosion, reduction equipment operating cost of Industrial Boiler.At present, have that a kind of application is commonplace, technology comparatively maturation should belong to heat and imitate the moisture film oxygen-eliminating device, its operation principle is to form the rotation moisture film in the rotation membrane pipe of oxygen-eliminating device, under centrifugal action in mouth of pipe place, form the downward water membrane skirt of rotation, and carry out heat exchange with from bottom to top steam, the steam critical-temperature with the water heating is overflowed the oxygen that is dissolved in the water.It has the following disadvantages technically: steam is little by bottom uphill process flow, and speed, heat energy all consume to some extent, has influenced the heat exchange efficiency of water, and a nearly step influences deaerating effect.

The utility model content

Technical problem to be solved in the utility model is: little at the steam flow that exists in the prior art, the water temperature raising speed is slow, problems such as thermal energy consumption is big are carried out technological improvement, change by heating steam and be ejected into vaporium by the heavy caliber steam jet, again step by step with the water heat exchange, like this can be so that water temperature raise fast, deaerating effect obviously improves.

The utility model can adopt following scheme to implement: it comprises deoxygenation head and the water tank two large divisions composition that links to each other with deoxygenation head bottom, and the top of deoxygenation head is provided with an exhaust outlet; The middle part is provided with hydroecium and water inlet pipe, outlet pipe, trickle bamboo comb, packing layer is installed on supporting plate, the bottom is equipped with steam pipe, it is characterized in that: be respectively equipped with outlet pipe 7 and water inlet pipe 15 in the left and right sides of hydroecium 6, steam pipe 21 and steam jet 13 are installed in the bottom steam chamber 19 of deoxygenation head.The upper end of hydroecium 6 is a upper spacer 4, and the lower end is a lower clapboard 8, and rotation membrane pipe 5 and communicating pipes 3 vertical uniform arrangement are at interval arranged between this two dividing plate.Be vaporium 19 below filler supporting plate 11, have a steam pipe 21 to be horizontally through in the bottom of vaporium 19, a steam jet 13 is installed at the middle part of steam pipe 21.Rotation membrane pipe 5 sees through upper spacer 4 and lower clapboard 8 respectively with the two ends up and down of communicating pipe 3, and on be fixed upper spacer 4 and the lower clapboard 8.

After above improvement, beneficial effect shows: the utility model deoxygenation rate obviously improves, and energy consumption has reduced significantly, and the repair and maintenance of critical component is become simple.

The specific embodiment

Oxygen-eliminating device comprises deoxygenation head and the water tank two large divisions composition that links to each other by flange 22 as described in Figure 1, and water tank is no longer carefully stated with of the prior art identical here, and only structure, the operation principle to the deoxygenation head is further described.The top of deoxygenation head is provided with a columnar exhaust outlet 1 in Fig. 1, and the bottom of exhaust outlet 1 is in the deoxygenation head and is provided with the through hole 2 that a plurality of exhausts are used, by this assembly drain oxygen and part steam.Below exhaust outlet 1, be provided with hydroecium 6, hydroecium 6 is formed by the certain space between upper spacer 4 and the lower clapboard 8, between two dividing plates, there are rotation membrane pipe 5 and communicating pipe 3 vertically to arrange at interval, rotation membrane pipe 5 sees through upper spacer 4 and lower clapboard 8 respectively with the two ends up and down of communicating pipe 3, and on be fixed upper spacer 4 and the lower clapboard 8.Be respectively equipped with outlet pipe 7 and water inlet pipe 15 in the left and right sides of hydroecium 6, need the water of deoxygenation to enter hydroecium 6 by water inlet pipe 15, excess electron excess fraction is discharged by outlet pipe 7 and is used as recirculated water.Steam pipe 21 and steam jet 13 are installed in the bottom steam chamber 19 of deoxygenation head.Between steam jet 13 and lower clapboard 8, be aligned in sequence with carriage 18, filler supporting plate 11, packing layer 10, discharger 9 and trickle bamboo comb 16 from down to up.

Operation principle is such, superheated steam is entered by steam pipe 21, spray orifice 17 through steam jet 13 is ejected in the vaporium 19, and by cover plate 20 aid dispersion, unnecessary steam is flow back to by blast pipe 14 circulations, and the air admission hole 12 on the vapour transmission filler supporting plate 11 in the vaporium 19 passes 16 heating of 10 pairs of trickle bamboo combs of packing layer again, pass rotation membrane pipe 5 at last, finish a working cycles.Entire work process water and steam circulated in countercurrent each other heat step by step, and water is from top to bottom, flow at last in the following water tank, and steam helps saving the energy from bottom to top.When steam passes through rotation membrane pipe 5, produce certain negative pressure, the water membrane skirt with the water in the hydroecium 6 sucks and formation is rotated helps heat exchange.Trickle bamboo comb 16 is that the steelwork by multilayer angle steel shape is staggered and forms, and helps forming bigger specific area, helps improving rapidly water temperature.The effect of packing layer 10 also is equally to help improving water temperature rapidly, reaches quick heating to water, and the oxygen that is dissolved in the water is discharged.
