The device is characterized by comprising a water inlet main pipe, wherein the water inlet main pipe is arranged on a water inlet distribution pipe; the two ends of the water inlet distribution pipe are respectively connected with two water inlet branch pipes; diffusers arranged on the water inlet branch pipes; and the water inlet branch pipes are connected with a pipe wall through hangers. The device provided by the invention has the characteristics of high energy utilization ratio, uniformity in heating, good deoxidization effect, small size, low cost and the like.
Description
Technical field
The present invention relates to a kind of nuclear power with hot colder section steam energy dissipating of deoxygenator equipment and heating unit, belong to Nuclear power plants 1,000,000 grade unit deoxygenator apparatus field.
Background technology
Deoxygenator is a key equipment of power plant's heat regenerative system.It is introduced the steam with certain pressure by in the deaerated water, is heated to the temperature of saturation under the deoxygenation pressure to water, reduces the solubleness of non coagulating gas in water, thereby reaches the purpose of deoxygenation, has prolonged the life-span of system device.
In nuclear power 1,000,000 grade power plant system, deoxygenator is accepted the main heating steam of steam turbine bypass discharge leg except needs, also will receive from hot cold section system again through post-decompression steam, as starting heating and underload voltage stabilizing.Deoxygenator plays the water storage function simultaneously as deaeration plant has huge expansion space, all adopts baffle arrangement but add hydrophobic entering deoxygenator inside like height in the past, and this structure can't be born the impact like the high pressure-temperature medium.
Summary of the invention
The objective of the invention is to solve prior art constructions and can't bear shock problem, provide a kind of energy utilization rate height, homogeneous heating, deaerating effect is good, volume is little, cost is low nuclear power with hot colder section steam energy dissipating of deoxygenator equipment and heating unit like the high pressure-temperature medium.
In order to achieve the above object; The invention provides a kind of nuclear power with hot colder section steam energy dissipating of deoxygenator equipment and heating unit, it is characterized in that, comprise water inlet manifold; Water inlet manifold is located at on the water distribution piping; Pipe coupling are propped up with two water inlets respectively in the two ends of water inlet distribution piping, and the water inlet arm is provided with scatterer, and the water inlet arm is connected with tube wall through suspension bracket.
Preferably, described water inlet manifold, the water inlet distribution piping with the water inlet arm vertical each other.
Preferably, described scatterer is provided with quakeproof bracket.
Preferably, every position at a distance from 3-18 scatterer is provided with a suspension bracket on the described water inlet arm.
Preferably, described scatterer is every is provided with a quakeproof bracket at a distance from 3-7 row.
The present invention has increased scatterer in deoxygenator inside; The hot colder section energy dissipating steam that produces during with nuclear power 1,000,000 grade unit startings carries out getting into deoxygenator equipment after the energy dissipating; Increased energy utilization rate, because surging force is big, the present invention is last to be provided with quakeproof bracket, suspension bracket carries out shock absorbing and fixes.Extracted steam from turbine when the present invention can accept cold reheated steam and operation simultaneously; Not only reduce the deoxygenator internal layout; Correspondingly reduce the volume of equipment, reduced the cost of equipment purchase and factory building investment, thereby improved the economy of power plant construction; Also effectively improved the deoxygenator effect, reduced deoxygenator operation noise and because of heating the uneven thermograde that occurs.

Embodiment
For making the present invention more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.
Like Fig. 1, Fig. 2, shown in Figure 3, be the structural representation of a kind of nuclear power with hot colder section steam energy dissipating of deoxygenator equipment and heating unit.The present invention be a kind of nuclear power with hot colder section steam energy dissipating of deoxygenator equipment and heating unit, comprise water inlet manifold 1, water inlet manifold 1 is located at on the water distribution piping 2; And connect each other; The two ends of water inlet distribution piping 2 are connected with two water inlet arms 3 respectively, are provided with scatterer 4 below the water inlet arm 3, and water inlet arm 3 is connected with tube wall 7 through suspension bracket 6; And water inlet the top of arm 3 whenever is provided with a suspension bracket 6 at a distance from the position of 9 scatterers 4, and scatterer 4 every rows at a distance from 3-7 are provided with a quakeproof bracket 5.Scatterer 4 is provided with quakeproof bracket 5, and water inlet manifold 1, water inlet distribution piping 2 and the arm 3 of intaking are vertical each other.
The working process of this invention is following:
Steam is got into by water inlet manifold 1, and reallocation gets into admission distribution piping 2, gets into admission arm 3 after being divided into two-way, gets into scatterer (energy dissipator) 4 again, and it is inner to utilize water to carry out injecting water tank after the energy dissipating, accomplishes whole process.Because the big need of surging force are provided with quakeproof bracket 5, suspension bracket 6 carries out shock absorbing and fixes.
