Description
Technical field
The present invention relates to a kind of heating unit that is used for circumferential weld, particularly, relate to a kind of heating unit that is used for the boiler header circumferential weld.
Background technology
The collection case also is header, and it is the part that connects with parts such as water wall, economizer, suphtrs, and water wall collection case, economizer collection case and suphtr collection case etc. are promptly arranged respectively.The effect of collection case is to compile or distribute carbonated drink working medium, reduces the conveying connecting tube of working medium, reduces the number of aperture of drum, thereby helps improving the safety performance of drum.At the water wall next part case of burner hearth both walls near the fire grate place, its effect is to prevent the coking of fire grate two sides, so be called anti-clinker box.
In fact the collection case is exactly the thick diameter pipe that is connected with a lot of small-bore pipe joints, and it is processed by weldless steel tube, two ends welding flat head (end cap).Open a lot of pores on the casing, in order to welding or expanded joint pipe.The two ends of economizer tube and superheater tube all are connected on the collection case, and the lower end of water wall is connected on the collection case, and the upper end both can be connected on the collection case, draw the minority pipe by the collection case again and receive on the upper drum, also can the water wall tube upper end directly be received on the upper drum.The effect of collection case in simple terms, comprises: 1) thorough mixing reduces thermal deviation, 2) communication passage is convenient to can meet the demands along flow arrangement minority pipeline.
The effect of boiler header generally has connection and cushions two effects.The picture water wall, the collection case effect that economizer and suphtr are imported and exported mainly has been a ligation, promptly connects multi units tube, so the weldless steel tube of the general DN250 of use is made usually.And the effect of steam collecting container mainly is a shock absorption, and promptly the buffering load is to the influence of boiler unit.
A collection case length often reaches 15 ~ 20m, in the collection case manufacturing processed, because the restriction of supplied materials size needs usually and will how to splice with the starting material pipe.Before splicing, need carry out preheating to this body circular seam of collection case, need carry out partial heat treatment to circumferential weld after the splicing.At present this body circular seam of collection case often adopts electric heating panel to coat the way that adds the woven asbesto covering and heat insulating when partial heat treatment, coats complex operation, heat-up rate is slow, heat insulation effect is bad, and under the situation that tube stub is housed on the collection case body, coats difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of heating unit that is used for circumferential seams of header; Be used for preheating and thermal treatment are carried out in the circumferential weld position of collection case butt joint; This device can the case body is local to coat to collecting easily, and thermal treatment is convenient, high insulating effect, and heat-up rate is fast and even.
In order to achieve the above object, the invention provides a kind of circumferential seams of header heating unit, this heating unit is for being nested with in the outside plate weldering formula anchor ear structure of collection case with the anchor ear form, and this anchor ear structure comprises:
The anchor ear housing;
Be arranged on the interior gas pipeline of anchor ear enclosure interior;
Be laid on described in the wire cloth of vesicular structure between the inwall of outer wall and anchor ear housing of gas pipeline;
Be arranged on some gas line and oxygen hose on the described anchor ear housing, be used to provide combustion gas and oxygen;
Wherein, also be provided with some apertures on the described interior gas pipeline, be used for the gas in the interior gas pipeline is evenly spread to wire cloth, fully burning.
Above-mentioned circumferential seams of header heating unit, wherein, described anchor ear structure is semicircle anchor ear.
Above-mentioned circumferential seams of header heating unit, wherein, described anchor ear structure is two symmetric semicircle anchor ears, these two anchor ears are connected to form an annulus through fixing part, and circumferential seams of header is coated fully.
Above-mentioned circumferential seams of header heating unit, wherein, described fixing part is a pin formula fixing part, two anchor ears is fixedly connected is arranged on the circumferential seams of header outside.
Above-mentioned circumferential seams of header heating unit wherein, is also set up the backing plate of different size between described heating unit and the collection case body, be used to adapt to the collection case body of different size.
Above-mentioned circumferential seams of header heating unit, wherein, described wire cloth is the wolfram steel silk screen, it act as the formation vesicular structure, makes the combustion gas can uniform distribution.
The present invention is through the form of anchor ear, reaches the effect of installing, coating of being easy to, through using the fuel gas buring heat supply; Combustion gas sees through the aperture on the interior gas pipeline, evenly spreads to fully burning of back on the wire cloth, and thermo-efficiency is high; Homogeneous heating and heat-up rate are fast, do not have obvious flare, and security is good.Through installing the backing plate of different size additional, heating unit of the present invention can adapt to the collection case body of different size specification.Simultaneously, the present invention can also separately use the preheating that is used to collect the case body by the two halves sheet.
Technological merit of the present invention is:
1. the efficient of clamping when having improved collection case product preheating and thermal treatment;
2. the problem that is difficult to coat when efficiently solving the partial heat treatment of band tube stub collection case;
3. the heating efficiency when having improved the partial heat treatment of collection case;
4. heat-up rate is fast, homogeneous heating, and can not tie the charcoal blackout;
5. wide accommodation can adapt to the collection case of different size.
