Abstract

A bearing super thermal conductive pipe exhausts heat recoverer relates to a boiler exhaust heat recoverer, which is arranged on a gas flue on the tail part of the boiler. The gas flows horizontally and the recoverer can absorb and utilize the exhaust heat discharged by the boiler. The utility model is technically characterized in that the upper part is provided with a bearing oval end plate; the middle part is provided with a round cylinder, one end of the cylinder is welded with the oval end plate and the other end is welded with a pipe plate; an intensified lacing wire is welded between the oval end plate and the pipe plate; the lower part of the pipe plate is welded with a gas tank; one end of a heat pipe is inserted into the round cylinder and the other end is inserted into the gas tank; in addition, the top of the oval end plate is welded with an instrument interface; a water inlet pipe and a water outlet can be directly connected with the water supply pipe of the original boiler; the original boiler pump is used to press the heat water in the recoverer into the boiler for direct recovery and utilization.

Description

But pressure-bearing super heat-conductive pipe waste-heat recoverer

Technical field:

But the utility model relates to a kind of pressure-bearing super heat-conductive pipe waste-heat recoverer.

Background technology:

Various boilers certainly will will be discharged fume, and the heat in therefore a large amount of high-temperature flue gas emits in vain.Cause the waste of the energy.Utilize hot pipe technique, but the super heat-conductive pipe waste-heat recoverer high efficiente callback waste heat that is made into.

But general common waste-heat recoverer is no pressure type, the condition of work that can not bear pressure, and cause when making by the dress application: 1. needing increases water circulating pump, has increased new power source consumption.2. also need increase a no setting-out case simultaneously, can cause radiation loss.Reduce organic efficiency.3. increase equipment investment, operation, expenses such as maintenance.

Summary of the invention:

And utility model " but pressure-bearing super heat-conductive pipe waste-heat recoverer " adopts hot pipe technique, by new body construction invention design, but adopts pressure restraining element, and reaching the utility model has the performance that can bear pressure.Simplify the equipment operation and used, more need not add many auxiliary devices.

A kind of " but super heat-conductive pipe waste-heat recoverer of pressure-bearing ", technical characterictic:

It mainly be by; But the ellipse head of pressure-bearing, round cylindrical shell one end and ellipse head welding are arranged at top, weld strength lacing wire between the other end and tube sheet welding, ellipse head and the tube sheet, tube sheet bottom welding smoke box, heat pipe one end insert in the cylinder, one end inserts in the smoke box, weld with tube sheet welding, ellipse head top in the middle of the heat pipe: the thermometer mouth, relief valve port, gauge port.

Textural association forms, but makes this utility model bearing capacity condition of work when using, and the hot water after realizing reclaiming directly heads into hot water in the boiler by former boiler water pump, and the waste heat recovery with 100% reaches energy-conservation purpose to boiler.

Description of drawings:

Be general illustration of the present utility model.

Among the figure:

The round cylindrical shell 5-of the 1-smoke box outlet 2-bottom smoke box 3-tube sheet 4-delivery port 6-ellipse head 7-thermometer mouth 8-intensity lacing wire 9-relief valve port 10-gauge port 11-heat pipe 12-water inlet 13-sewage draining exit 14-smoke box import 15-condensation mouth of a river.

Specific embodiments:

With equipped 2 tons of boilers is example:

1. according to relevant strength calculation formula, but calculate the cylindrical shell and the seal head material thickness of bearing pressure.

2. adopt ￠ 800 * 8 end sockets (6) and rolling ￠ 800 * 700 * 8 cylindrical shells (4) with 32.5 108 holes of ￠ 800 tube sheets (3) boring ￠.And weld with cylindrical shell (4).

3. ￠ 32 heat pipes (11) are inserted in the tube, and weld with tube sheet (3).

4. with outer each joint weld of cylindrical shell (4).Carry out the water pressure test then.Ne-leakage is checked in pressurize 30 minutes.

5. weld lower part box (2).

Should " but pressure-bearing super heat-conductive pipe waste-heat recoverer " making implement to finish.

Claims (1)

1. one kind " but super heat-conductive pipe waste-heat recoverer of pressure-bearing ",

Technical characterictic:

It mainly be by; But the ellipse head of pressure-bearing, round cylindrical shell one end and ellipse head welding are arranged at top, weld strength lacing wire between the other end and tube sheet welding, ellipse head and the tube sheet, tube sheet bottom welding smoke box, heat pipe one end insert in the cylinder, one end inserts in the smoke box, weld with tube sheet welding, ellipse head top in the middle of the heat pipe: the thermometer mouth, relief valve port, gauge port.
