Abstract

The utility model discloses a boiler is row steam extraction spray set surely, including arranging jar, industrial water pond surely and arranging the water drainage tank surely, the top fixedly connected with steam exhaust pipeline of arranging the jar surely. The utility model discloses a be provided with surely arrange the jar, manual valve, the hydrophobic pump, the industry pond, spray set and exhaust steam pipe, because the higher water source of temperature such as boiler drum and downcomer can the hydrophobic flow to surely arranging the jar in among the thermal power, the water that is in surely arranging the jar can produce the vaporization because the higher reason of temperature, discharge through the exhaust steam pipe after the vaporization, the inside water of spray set sprays from deciding the steam from bottom to top of arranging the jar through the round hole on spray set surface, steam can arrive surely arranging the jar inside after meeting the shower water, at this in-process, because spray set meets with the industry pond through spray set, surely arrange the water drainage tank and pass through the hydrophobic pump and advance water toward the inside in industry pond, only need manually open manual valve, just can realize the effect that water source circulation used.

Description

Fixed-exhaust steam spraying device for boiler

Technical Field

The utility model relates to a thermal power plant technical field, in particular to boiler fixed-row steam-discharging spray set.

Background

Thermal power generation is a power generation method in which thermal energy generated by combustion of combustible materials is converted into electrical energy by a power generation device.

In the thermal power generation at the present stage, after a fixed-row pressure container in a boiler works for a long time, the phenomenon of fixed-row steam emission and steam emission easily exists, so that the ground ice accumulation below the fixed row in winter has potential safety hazards, the long-term steam emission influences energy-saving indexes, and a device capable of spraying the fixed-row steam emission of the boiler is urgently needed to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a boiler is row steam extraction spray set surely can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a boiler is row steam extraction spray set surely, includes row's jar, industrial water pool and row's water drainage tank surely, the top fixedly connected with steam extraction pipeline of row's jar surely, steam extraction pipeline's inside middle part fixedly connected with spray set, the top one end of row's water drainage tank surely is passed through screw fixedly connected with drain pump, the drain pump is connected with the industrial water pool, the one end in industrial water pool is connected with steam extraction pipeline through spray piping, spray piping's one end is provided with manual valve.

Furthermore, the spraying device adopts a DN20 carbon steel pipeline, round holes are formed in the surface of the spraying device, and the spraying device is in a spiral structure.

Further, the manual valve is a DN25 manual valve.

Furthermore, the top end of the steam exhaust pipeline is opened, and a flash tank is arranged at the top end of the steam exhaust pipeline.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1): the utility model discloses a be provided with surely arrange the jar, manual valve, the hydrophobic pump, the industry pond, spray set and exhaust steam pipe, because the higher water source of temperature such as boiler drum and downcomer can the hydrophobic flow to surely arranging the jar in among the thermal power, the water that is in surely arranging the jar can produce the vaporization because the higher reason of temperature, discharge through the exhaust steam pipe after the vaporization, the inside water of spray set sprays from deciding the steam from bottom to top of arranging the jar through the round hole on spray set surface, steam can arrive surely arranging the jar inside after meeting the shower water, at this in-process, because spray set meets with the industry pond through spray set, surely arrange the water drainage tank and pass through the hydrophobic pump and advance water toward the inside in industry pond, only need manually open manual valve, just can realize the effect that water source circulation used.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1. arranging the tanks in a fixed manner; 2. a spraying device; 3. a steam exhaust duct; 4. a manual valve; 5. a fixed drainage groove; 6. a drain pump; 7. an industrial water pool; 8. and (4) a spray pipeline.

Detailed Description

Technical means for realizing the utility model; authoring features; the purpose and function are easily understood and appreciated, and the present invention will be further described with reference to the following detailed description.

As shown in fig. 1, a boiler is row steam spray set surely, including row jar 1 surely, industrial water pool 7 and row water drainage tank 5 surely, the top fixedly connected with steam exhaust pipe 3 of row jar 1 surely, steam exhaust pipe 3's inside middle part fixedly connected with spray set 2, the top one end of row water drainage tank 5 surely is passed through screw fixedly connected with drain pump 6, drain pump 6 is connected with industrial water pool 7, the one end in industrial water pool 7 is connected with steam exhaust pipe 3 through spray piping 8, spray piping 8's one end is provided with manual valve 4.

The spraying device 2 adopts a DN20 carbon steel pipeline, a round hole is formed in the surface of the spraying device 2, and the spraying device 2 is in a spiral structure.

Wherein, the manual valve 4 is DN25 manual valve.

Wherein, the top of exhaust pipe 3 is opened, the top of exhaust pipe 3 is provided with the flash tank.

It should be noted that, the utility model relates to a boiler fixed-row steam-discharging spray device, in the using process, firstly, because the boiler steam drum drainage and the downcomer drainage can drain water towards the inside of the fixed-row tank 1, at this time, the inside of the fixed-row tank 1 can generate steam from bottom to top because of higher temperature of water, the steam inside the fixed-row tank 1 can be discharged through the steam-discharging pipeline 3, the manual valve 4 is opened, because the spray device 2 is connected with the industrial water pool 7 through the spray pipeline 8, the fixed-row water-discharging groove 5 can inject water into the industrial water pool 7 through the steam-discharging pump 6, thereby the water inside the industrial water pool 7 can be injected into the spray device 2 through the spray pipeline 8, the water can be sprayed towards the inside of the steam-discharging pipeline 3 through the round holes around the surface of the spray device 2, in the process, the steam inside the steam-discharging pipeline 3 can form water after being contacted with the spray water and then returns to the inside the, thereby realizing the effect of water recycling.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
