Description

Guide plate of indirect air cooling radiator pipe box

Technical Field

The utility model relates to a guide plate of indirect air cooling radiator pipe case belongs to power station cooling technical field.

Background

The indirect air cooling tower for power station is a steam cooling technology adopted in the thermal power plant in coal-rich and water-poor areas in China in recent years. The core elements of the technology, namely the tube plate and the base tube of the water inlet pipe box of the air-cooled condenser, are washed by circulating water of the system for a long time, are very easy to damage and leak, and the water inlet pipe box and the base tube need to be frequently repaired or replaced, thus seriously affecting the normal operation of a power station. The pipe box is detached after the pipe bundle of the radiator of the early indirect air cooling tower leaks, and the pipe orifice is observed to be damaged by flushing and an irregular gap is formed. The direction of the notch has definite directionality corresponding to the water flow direction.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the problem of how to reduce rivers and erode base tube and pipe case inner wall when rivers strike lower pipe case water inlet is solved.

In order to solve the technical problem, the technical scheme of the utility model a guide plate of indirect air cooling radiator pipe case is provided, a serial communication port, including the bottom plate, the both sides of bottom plate are equipped with the top respectively all with first curb plate and the second curb plate of pipe case inner wall top welded fastening, are equipped with the aperture that a plurality of sizes and interval accord with the fluid flow rate uniform requirement on the bottom plate, all are equipped with a hole of guaranteeing the liquid circulation and satisfying the curb plate bearing capacity requirement on first curb plate and the second curb plate.

Preferably, the bottom plate is provided with a plurality of small holes with equal diameters and equal pitches which are arranged in a staggered mode.

Preferably, the plurality of small holes on the bottom plate are symmetrically distributed on two sides of the bottom plate.

Preferably, both ends of the bottom plate are arc-shaped structures.

Preferably, a distance for ensuring liquid circulation and installation space is arranged between each of the first side plate and the second side plate and the inner wall of the tube box.

Preferably, the holes on the first side plate and the second side plate are arranged at the water outlet of the tube box.

Compared with the prior art, the utility model has the following advantage:

the utility model provides a guide plate is installed in pipe case water inlet department, bear the direct impact that gets into pipe case rivers, and guide rivers through aperture and specific basin on the guide plate, make the fluid distribution that gets into in pipe case and the tube bank even, show to reduce inhomogeneous rivers and horizontal high-speed rivers to the erosion of parent tube and pipe case inner wall, effectual pipe case inner wall and tube bank parent tube of having protected, extension tube bank life has realized the purpose of the indirect air cooling system of protection stability, economic operation.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the present invention relates to a flow guiding plate for an indirect air cooling radiator pipe box, which is fixed on the water inlet side of the pipe box 4 by welding, the right side of the pipe box 4 is a water inlet chamber, and the left side is an outlet chamber. As shown in fig. 2, the utility model discloses a guide plate comprises bottom plate 1, first curb plate 2, second curb plate 3, and bottom plate 1, first curb plate 2, second curb plate 3 welding are in the same place. The tops of the first side plate 2 and the second side plate 3 are welded and fixed with the top of the inner wall of the tube box. As shown in FIG. 4, the bottom plate 1 is provided with a plurality of small holes, the hole areas of the bottom plate 1 are symmetrically distributed on both sides of the bottom plate 1, and the holes are staggered with equal diameter and equal pitch, as shown in FIG. 5. The size and the spacing of the holes meet the requirement of uniform flow rate of fluid, the end part of the bottom plate 1 is trimmed into an arc shape as shown in figure 3, namely, both ends of the bottom plate 1 are of arc-shaped structures, so that the impact resistance is improved; holes are respectively formed in the first side plate 2 and the second side plate 3, so that liquid circulation is guaranteed, and the bearing capacity requirement of the side plates is met; the space between the two side plates (namely the first side plate 2 and the second side plate 3) and the inner wall of the tube box 4 is designed to ensure the liquid circulation and installation space. The holes on the first side plate 2 and the second side plate 3 are arranged at the water outlet of the tube box 4.

As shown in fig. 1, through using the utility model discloses a behind the guide plate, after rivers get into pipe case 4, direct impact is to the bottom plate 1 on, the direction of rivers is shown as the arrow direction in fig. 1, the parent tube 5 on having avoided rivers direct impact pipe case 4, the side of rivers then erodees first curb plate 2 and second curb plate 3, avoided rivers direct erode pipe case inner wall 6 of pipe case 4 side, the export outflow of the hole of rivers following on first curb plate 2 and the second curb plate 3 and pipe case 4 side after slowing down afterwards.
