Abstract
A kind of tube sheet, comprise hole B, hole A, tube sheet center arranges porose A, tube sheet surface uniform is provided with several holes B, be evenly equipped with several screwed holes at the tube sheet back side, described tube sheet front is provided with an annulus groove, and tube sheet cylindrical is provided with a shoulder hole, be provided with a blind hole communicating with shoulder hole in the front of tube sheet, blind hole communicates with annulus groove.The utility model is rational in infrastructure, filth-discharging effect good, has improved the service life of equipment.
Description
Technical field:
The utility model relates to waste heat boiler parts, specially refers to a kind of tube sheet.
Background technology:
In recent years, along with the significantly rise of various energy prices, people start to consider emphatically its operating cost to the selection of boiler, enterprise produce from not steam boiler, the fuel cost of boiler is a very large expenditure.The shortage of the energy is the serious test that the current whole world all faces, seeking development under such overall background, and tapping a new source of energy is an aspect, the more important thing is and is saving the energy foot time up and down.And in the industrial process such as smelting, generating, not only contaminated environment but also waste energy of the generation of a large amount of high-temp waste gas, so the design and development of afterheat energy-saving boiler receives much concern.Thermal source enters in waste heat boiler cylindrical shell from import, to restraining interior water heating, uses after a period of time, in cylindrical shell and the outer weekly assembly generation of tube bank dirt, existing equipment shell side cannot mechanical cleaning, and filth-discharging effect is bad, after tube bank corrosion, scrap together with cylindrical shell, equipment life is lower.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, tube sheet that filth-discharging effect is good.
The purpose of this utility model is achieved in that a kind of tube sheet, tube sheet center is provided with centre bore, tube sheet surface uniform is provided with several holes, be evenly equipped with several screwed holes at the tube sheet back side, it is characterized in that: described tube sheet front is provided with an annulus groove, tube sheet cylindrical is provided with a shoulder hole, is provided with a blind hole communicating with shoulder hole in the front of tube sheet, and blind hole communicates with annulus groove.
The utility model is rational in infrastructure, filth-discharging effect good, has improved the service life of equipment.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1 along B-B;
Fig. 3 is the cutaway view of Fig. 1 along A-A;
1. tube sheets in figure, 2. hole A, 3. hole B, 4. screwed hole, 5. blind hole, 6. annulus groove, 7. shoulder hole.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, a kind of tube sheet, comprise hole 3, hole 2, it is porose 2 that tube sheet 1 center arranges, and tube sheet surface uniform is provided with several holes 3, is evenly equipped with several screwed holes 4 at the tube sheet back side, it is characterized in that: described tube sheet front is provided with an annulus groove 6, tube sheet cylindrical is provided with a shoulder hole 7, is provided with a blind hole communicating with shoulder hole 5 in the front of tube sheet, and blind hole 5 communicates with annulus groove 6.When concrete enforcement, in the shoulder hole of tube sheet, be connected with blow-off pipe, thermal source enters in waste heat boiler cylindrical shell from import, to restraining interior water heating, use after a period of time, in shell side, can produce dirt, dirt is on tube sheet, and the blow-off pipe entering in blind hole from the side by ring channel concentrated flow is discharged.
