Abstract

The utility model discloses a novel steam distribution device, which belongs to a part of heat transfer equipment for heat exchange through direct steam and water mixing, in particular a distribution device for delivering steam into the equipment. The novel steam distribution device comprises a main pipe which is fixed by a bracket and is provided with a steam lead-in pipe, wherein the two ends of the main pipe are sealed by stop plates. The novel steam distribution device is characterized in that: the main pipe is provided with at least six branch pipes which are perpendicular to the main pipe; the tail ends of the branch pipes are connected with spray pipes with uniformly distributed spray holes on the walls; and the tail ends of the spray pipes are provided with spray pipe stop plates. The number of the branch pipes is determined according to steam consumption required by the equipment. The novel steam distribution device has the beneficial effects that: water hammer and cavitation can be effectively relieved; overlarge vibration and noise of the equipment are avoided during starting and low-load operation; long-term stable operation of the equipment under various variable working conditions is facilitated; and therefore, safe operation of an entire boiler unit system is guaranteed. The device has a simple structure, is easy to reconstruct on the original basis and has good economical benefit and social benefit.

Description

Novel vapor distribution device

Technical field

The utility model belongs to the parts of the direct heat of mixing exchange of carbonated drink heat-transfer equipment, especially for the distributor of delivering vapor access arrangement.

Background technology

Thermal deaerator be a kind of in station boiler, industrial boiler system widely used equipment, a kind of device that seethes with excitement again can be set in this equipment water storage tank, fix with support and equipment.When device start and underrun, using, mainly is that heating steam is introduced device interior through this device, and Fast Heating water makes the water in the water tank remain on saturation state to reach the deoxygenation purpose.It comprises that steam inlet tube and the trunk line that has a fumarole see Fig. 2, does not start or during heavy-duty service, is water-filled in this pipeline at equipment; When device start or underrun, begin to get into steam in this pipeline, the rapid heat exchange of water that steam is rapid and pipe is interior; Because this pipe diameter is bigger; Portion produces water attack and cavitation erosion within it, produces huge vibrations and noise, and connecting line and instrument, valve around equipment is reached form damaging impact.Unstable when the control system, feed quantity of steam when big, also can be in short-term destruction equipment, cause whole machine set system normally to move.

The utility model content

Be prone to produce the deficiency of water attack and cavitation erosion in order to overcome the existing device that seethes with excitement again with steam distribution function; Utility model provides a kind of novel vapor distribution device; This novel vapor distribution device can alleviate water attack and cavitation erosion, can not cause the noise and vibration that equipment is excessive.

The utility model solves the technical scheme that its technical problem adopted: a kind of novel vapor distribution device; Comprise by the fixing person in charge that the steam inlet tube is housed of support; Be responsible for the two ends envelope closure plate is arranged; It is characterized in that: the person in charge is last is equipped with 6 perpendicular arms at least, and the arm end is connecting the jet pipe that has equally distributed spray orifice on the wall, and the jet pipe end is equipped with the jet pipe closure plate.

Described arm is the 6-20 root.The quantity of arm is confirmed according to the required steam consumption of equipment.

To be responsible for the top that is fixed on water storage tank through support when this vapor distribution device is used, draw several small dimension arms as steam-distributing pipe, and weld the stainless steel jet pipe in the arm lower end from being responsible for.So only there are part arm and jet pipe to be in below the water tank low water level.When equipment does not start or during heavy-duty service, only in arm, has a spot of water; When device start and underrun, steam can be rapidly with outside heating of the water in the pipe and the blow-off pipe, and little vibration only produces on arm, is delivered to when being responsible for to have weakened, can not cause the noise and vibration that equipment is excessive.Even equipment needs for a long time operation in this state, the jet pipe of stainless steel control also can play the effect of long-time erosion resistant fully.The utility model can guarantee equipment can be under various variable working condition operation steady in a long-term, thereby guaranteed the safe operation of whole boiler machine set system.

The beneficial effect of the utility model is effectively to alleviate water attack and cavitation erosion; When startup and underrun, can not cause the noise and vibration that equipment is excessive; Help assurance equipment can be under various variable working condition operation steady in a long-term, thereby guaranteed the safe operation of whole boiler machine set system.Apparatus structure is simple, be easy to reequip on the original basis, and good economic benefit and social benefit are arranged.

Description of drawings

Fig. 1 is the structural representation of the utility model,

Fig. 2 is the prior art constructions sketch map,

Fig. 3 be the A-A of Fig. 2 to view,

Fig. 4 is that the B-B of Fig. 1 is to view.

Among the figure, 1. support 2. is responsible for, 21. fumaroles, 3. inlet tube, 4. closure plate, 5. arm, 6. jet pipe, 61. spray orifices, 7. jet pipe closure plate.

The specific embodiment

The specific embodiment of the utility model is, and is as shown in the figure:

Embodiment 1; A kind of novel vapor distribution device; Comprise the person in charge that steam inlet tube 3 is housed 2 who is fixed by support 1, being responsible for the two ends envelope has closure plate 4, it is characterized in that: 12 perpendicular arms 5 are housed on the person in charge of steel pipe manufacturing; The arm end is connecting the stainless steel jet pipe 6 that has equally distributed spray orifice 61 on the wall, and the jet pipe end is equipped with jet pipe closure plate 7.To be responsible for the top that is fixed on water storage tank through support when this vapor distribution device is used, draw several small dimension arms as steam-distributing pipe, and weld the stainless steel jet pipe in the arm lower end from being responsible for.The quantity of arm can confirm so only have part arm and jet pipe to be in below the water tank low water level according to the required steam consumption of equipment in concrete the application.When equipment does not start or during heavy-duty service, only in arm, has a spot of water; When device start and underrun, steam can be rapidly with outside heating of the water in the pipe and the blow-off pipe, and little vibration only produces on arm, is delivered to when being responsible for to have weakened, can not cause the noise and vibration that equipment is excessive.

Claims

1. novel vapor distribution device; Comprise by the fixing person in charge that the steam inlet tube is housed of support; Be responsible for the two ends envelope closure plate is arranged; It is characterized in that: the person in charge is last is equipped with 6 perpendicular arms at least, and the arm end is connecting the jet pipe that has equally distributed spray orifice on the wall, and the jet pipe end is equipped with the jet pipe closure plate.

2. novel vapor distribution device according to claim 1 is characterized in that: described arm is the 6-20 root.
