Description
Technical field
The utility model relates to a kind of blowdown apparatus, particularly a kind of header blowdown apparatus.
Background technology
At present, the advantage that tubular boiler is large with its heat transfer area, boiler efficiency is high instead of shell boiler gradually, header is the important component part of tubular boiler, the Main Function of header is collected working medium, or working medium is re-assigned in other pipeline, namely working medium collected, mix and reallocate, ensure uniform distribution and the heating of working medium.After boiler operatiopn a period of time, can form dirt accumulation bottom header, periodical blowdown cannot thoroughly blowdown, boiler circulating effect if things go on like this can be caused bad, even occur that booster affects the safe operation of boiler.In order to ensure that blowdown is thorough, the header of large gauge needs operating personnel to enter header inside installation blowdown mother pipe, then is communicated with the blow-off pipe bottom header by blowdown mother pipe, and blowdown mother tubular construction is complicated, complex installation process; The header specification of existing boiler is less, and operating personnel cannot enter header inside and install blowdown mother pipe, causes the periodical blowdown of small dimension header not thorough, has had a strong impact on circulating effect and the safety in utilization of boiler.
Utility model content
The utility model, in order to solve the halfway problem of existing small dimension header periodical blowdown, provides a kind of header blowdown apparatus.
The utility model in order to solve the problems of the technologies described above the technical scheme taked is: header blowdown apparatus of the present utility model comprises header, angle steel, blow-off pipe, two end caps and two closure plates; Communicate with the bottom of header in the middle part of the bottom surface that blow-off pipe is arranged on header, the inner length direction along header of header is provided with angle steel, angle steel is equal leg angle, the opening of angle steel is towards blow-off pipe, the middle part of a side plate of angle steel is evenly provided with multiple angle steel through hole along the length direction of angle steel, the two ends of angle steel are welded with a closure plate respectively, and the bottom of two closure plates is welded with the inwall of header respectively, and two end caps are separately positioned on the both sides of header.
The beneficial effects of the utility model are:
1, the utility model manufacturing process is simple, by opening hole on a side plate of angle steel, before header both sides end cap is not closed, angle steel good for assembly welding and closure plate are inserted header, the welding of closure plate and header inwall only need be carried out in the two-port of header, enter header inside without the need to operating personnel to install, dirt in header flows into angle steel inside by angle steel through hole and then flows out blow-off pipe, periodical blowdown is thorough, not only be applicable to the periodical blowdown of small dimension header, be also applicable to the periodical blowdown of large gauge header;
2, the utility model structure is simple, is easy to realize, with low cost, can eliminate the dirt accumulation in header, improve boiler circulating effect, improves the safety in utilization of boiler.
