Abstract

The utility model relates to a water supply and deaeration technique for boilers, in particular to a novel towerless and multi-tube rotating-film deaerator. A steam nozzle and a rotating-film tube are not needed to be aligned during installation of the deaerator. The deaerator comprises a water tank, wherein a water mixing tube and steam tubes are arranged in the water tank; steam nozzles are the steam tubes; steam tubes are set to be two paths, including a primary steam tube and a secondary steam tube; a steam nozzle of the primary steam tube corresponds to a rotating-film tube; the steam tubes and the water mixing tube corresponding to the steam nozzles and the rotating-film tube are arranged in one chamber; the water mixing tube in the chamber forms a mixing water chamber, the steam tube in the chamber forms a steam chamber; and a water and film skirt chamber is formed between the water mixing tube and the steam tube. According to the novel towerless and multi-tube rotating-film deaerator, not only are calibration processes during installation reduced, but also water entering the water tank can be preheated in the chamber.

Description

Novel without tower multitube membrane deaerator

Technical field

The utility model relates to a kind of Oxygen Removal Technology for Boiler Feedwater, specifically, relates to a kind of novel without tower multitube membrane deaerator.

Background technology

Large-scale power station and Industrial Boiler are the corrosion of anti-block both at home and abroad, oiler feed must be carried out the deoxygenation processing through deoxygenator, and at present, this kind deoxygenator has various ways, as: vertical single tower, vertical multitower, Wo Ta, several without tower etc., have the tower deoxygenator all to exist body large, it is large, highly high to take up space, pipeline and system complex, cost of manufacture is high, and shock resistance is poor, and separate unit is exerted oneself little, life-span is short, the sliding pressure operation scope is little, and the load variations scope is little, and noise is large, the water outlet oxygen level is high, working cost is high, twin containers structure, the apparent in view shortcoming such as obviously of stress concentration, for above shortcoming, my company has developed a kind of novel without the tower membrane deaerator in 2004, the patent No. is: ZL 2,004 2 0073781.9, sees through this several years makes, still also come with some shortcomings, the one, female form of tubes vapor-nozzle and integrated rotation membrane pipe difficulty is installed, size deviation is difficult to control, the center is difficult to centering about rotation membrane pipe and the vapor-nozzle.

Summary of the invention

The utility model overcomes defects, provide a kind of do not need when mounted with vapor-nozzle and rotation membrane pipe aim at novel without tower multitube membrane deaerator.

Novel technical scheme without tower multitube membrane deaerator of the present utility model is such: it comprises water tank, the mixed pipe of water is set in the water tank, vapour pipe, vapour pipe arranges vapor-nozzle, vapour pipe is set to two-way and is distributed as primary steam pipe and secondary steam pipe, the primary steam pipe is arranged on the mixed pipe of water below, secondary steam pipe extends to the bottom of water tank, the vapor-nozzle of primary steam pipe and rotation membrane pipe are corresponding one by one, the mixed pipe of the vapour pipe of vapor-nozzle and rotation membrane pipe corresponding position and water is arranged in the chamber, the mixed pipe of water in the chamber forms and mixes hydroecium, vapour pipe in the chamber forms sweating room, forms the water membrane skirt chamber between the mixed pipe of water and the vapour pipe.

Optimally, vapor-nozzle and rotation membrane pipe arrange two groups at least.

Optimally, the chamber downside sets out the mouth of a river.

Of the present utility model novel without tower multitube membrane deaerator because will need the one to one part of the mixed pipe of vapour pipe and water, before installation, just process, this part is arranged in the chamber, not only reduce the calibration procedure when installing, and in chamber, can also before entering the water extraction in the water tank, carry out preheating.

Description of drawings

Fig. 1 is novel structural representation without tower multitube membrane deaerator of the present utility model.

1-water tank, 2-primary steam pipe, the mixed pipe of 3-water, 4-rotation membrane pipe, 5-mixing hydroecium, 6-vapor-nozzle, 7-water membrane skirt chamber, 8-sweating room, 9-water outlet.

Embodiment

As shown in the figure, it is of the present utility model that novel it comprises water tank 1 without tower multitube membrane deaerator, the water tank 1 interior mixed pipe 3 of water that arranges, vapour pipe 2, vapour pipe arranges vapor-nozzle, vapour pipe is set to two-way and is distributed as primary steam pipe 2 and secondary steam pipe, primary steam pipe 2 is arranged on the mixed pipe of water 3 belows, secondary steam pipe extends to the bottom of water tank 1, the vapor-nozzle 6 of primary steam pipe 2 and rotation membrane pipe 4 are corresponding one by one, vapor-nozzle 6 and rotation membrane pipe 4 are corresponding one by one, the mixed pipe 3 of the vapour pipe 2 of vapor-nozzle 6 and rotation membrane pipe 4 corresponding positions and water is arranged in the chamber, the mixed pipe 3 of water in the chamber forms and mixes hydroecium 5, and the vapour pipe 2 in the chamber forms sweating room 8, forms water membrane skirt chamber 7 between the mixed pipe 3 of water and the vapour pipe 2.Vapor-nozzle 6 and rotation membrane pipe 4 arrange two groups at least.The chamber downside sets out the mouth of a river 9.

Novel mechanism without tower multitube membrane deaerator of the present utility model is such, water enters into the mixed pipe 3 of water from entrance and arrives chamber, steam enters into vapour pipe 2 chambers from the steam-in, then water is from the lower water membrane skirt that forms of rotation membrane pipe 4 sprays of the mixed pipe 3 of water, steam upwards is sprayed onto water membrane skirt from the vapor-nozzle 6 of vapour pipe 5,7 interiorly carry out preheating to water in the water membrane skirt chamber, the water after the preheating below chamber water outlet 9 flow into water tanks 1, then reheated by the vapour pipe in the water tank.

This structure novel without tower multitube membrane deaerator not only do not need vapor-nozzle and rotation membrane pipe are calibrated in installation process, and can carry out preheating to the water in the water tank, and the heating deaerating effect is very good, can widespread use in this area.
