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. The deaerator comprises a water tank, wherein a water mixing tube and steam tubes are arranged in the water tank; steam tubes comprise a primary steam tube and a secondary steam tube; steam nozzles are arranged on the steam tubes; a rotating-film tube is arranged in the water tank; and a primary steam nozzle of the primary steam tube corresponds to the rotating-film tube, the secondary steam tube stretches horizontally to two sides at the bottom of the water tank, and a secondary steam nozzle is arranged on the periphery of the secondary steam tube in a spiral shape. According to the novel towerless and multi-tube rotating-film deaerator, when steam of the secondary steam tube enters the water tank, as the nozzles are distributed at peripheries of the steam tubes in spiral shapes, steam forms spiral air flows at the bottom of the water tank, and turbulent flows to water in the water tank are formed, so that uniform heating is achieved.
Description
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 deoxygenation through deoxygenator and process, at present, this kind deoxygenator has various ways, as: vertical single tower, vertical multitower, Wo Ta, several without tower etc., there is the tower deoxygenator all to exist body large, it is large to take up space, highly high, pipeline and system complex, cost of manufacture is high, and shock resistance is poor, separate unit is exerted oneself little, life-span is short, and the sliding pressure operation scope is little, and the load variations scope is little, noise is large, the water outlet oxygen level is high, and working cost is high, the twin containers structure, the apparent in view shortcoming such as obviously of stress concentration, for above shortcoming, my company developed a kind of novel without the tower membrane deaerator in 2004, and the patent No. is: ZL 2,004 2 0073781.9, see through this several years makes, still also come with some shortcomings, the one, vapor-nozzle is set to follow the arm that vapour pipe stretches out more, extends to the bottom of water tank always, like this owing to the descending distance of steam is larger, so dynamics will reduce, and nozzle is to be in a height, like this during steam heating, water in the water tank will form laminar flow, heats inhomogeneous.
Summary of the invention
The utility model overcomes defects, provides a kind of vapor-nozzle of vapour pipe to form spiral air flow at water tank bottom, thereby the water in the water tank is carried out the novel without tower multitube membrane deaerator of homogeneous heating.
Novel technical scheme without tower multitube membrane deaerator of the present utility model is such: it comprises water tank, the mixed pipe of water, vapour pipe are set in the water tank, vapour pipe comprises primary steam pipe, secondary steam pipe, vapour pipe arranges vapor-nozzle, the mixed pipe of water arranges rotation membrane pipe, the primary steam nozzle of primary steam pipe and rotation membrane pipe are corresponding one by one, secondary steam pipe extends to water tank bottom, secondary steam pipe laterally extends to both sides at water tank bottom, and the secondary steam nozzle is arranged in around the secondary steam pipe twist.
Optimally, secondary steam nozzle place arranges jet pipe.
Of the present utility model novel without tower multitube membrane deaerator when the steam of secondary steam pipe enters into water tank, because nozzle is to be spiral type to be distributed in around the vapour pipe, so steam forms spiral air flow at water tank bottom, the water in the water tank is formed flow-disturbing, realize homogeneous heating.
Description of drawings
Fig. 1 is novel structural representation without tower multitube membrane deaerator of the present utility model.
1-water tank, 2-jet pipe, 3-secondary steam pipe, 4-primary steam pipe, the mixed pipe of 5-water, 6-primary steam nozzle, 7-rotation membrane pipe.
Embodiment
Embodiment 1:
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 5 of water, the vapour pipe 3,4 of arranging, vapour pipe comprises primary steam pipe 4, secondary steam pipe 3, vapour pipe arranges vapor-nozzle, the mixed pipe 5 of water arranges rotation membrane pipe 7, the primary steam nozzle 6 of primary steam pipe 4 and rotation membrane pipe 7 are corresponding one by one, secondary steam pipe 3 extends to water tank 1 bottom, secondary steam pipe 3 extends to both sides in water tank 1 bottom transverse, and the secondary steam nozzle is arranged in around the secondary steam pipe 3 twist.Secondary steam nozzle place arranges jet pipe 2.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that the vapor-nozzle place of the secondary steam pipe of present embodiment does not arrange jet pipe.
This structure novel simple in structure without tower multitube membrane deaerator, heats is good, can widespread use in this area.
Claims (2)
- One kind novel without tower multitube membrane deaerator, it comprises water tank, the mixed pipe of water, vapour pipe are set in the water tank, and vapour pipe comprises primary steam pipe, secondary steam pipe, and vapour pipe arranges vapor-nozzle, the mixed pipe of water arranges rotation membrane pipe, the primary steam nozzle of primary steam pipe and rotation membrane pipe are corresponding one by one, and secondary steam pipe extends to water tank bottom, it is characterized in that, secondary steam pipe laterally extends to both sides at water tank bottom, and the secondary steam nozzle is arranged in around the secondary steam pipe twist.
- 2. according to claim 1ly novelly it is characterized in that without tower multitube membrane deaerator secondary steam nozzle place arranges jet pipe.
