Abstract

The utility model discloses a boiler steam heating device, which mainly comrises a smoke tank 5, a steam heating pipe 4, a steam communicating pipe 4 or 41', a round-sky-square-earth port 2 or a square-sky-round-earth port 6, a steam inlet pipe 8 and a steam outlet pipe 3. When the waste heat smoke in vertical or horizontal water pipe or fire pipe boilers burning coal (or fuel and gas) enters the smoke tank 5 from the smoke inlet, the waste heat smoke fills the smoke tank 5 and circulates in the smoke tank 5, thus heating the steam which enters the steam heating pipe 4 from the steam inlet pipe 8; the steam temperature can achieve the steam temperature in the boiler water pipe with a pressure of 0.4 to 0.7MPa. The heated steam is sent to industrial or civil places from the steam outlet pipe 3; the waste heat smoke is discharged at the smoke outlet after circulating in the smoke tank 5. The boiler steam heating device can be widely applied to medium and small industrial and civil places.

Description

The Boiler Steam heating device

Technical field the utility model relates to a kind of Boiler Steam heating device that is applied to vapor (steam) temperature in the steam boiler for domestic heating steam pipeline (trace), relates in particular to a kind of device that is used for low pressure boiler for domestic jet chimney vapor (steam) temperature.

The civilian middle-size and small-size water-tube boiler of background technology generally adopts fire coal to act as a fuel, and when fire coal water in the heating boiler after combustion chambers burn becomes water vapour, delivers a vapor to each workplace (as bathroom or dining room etc.) by conveyance conduit again.Flue gas behind the fired coal combustion (temperature is generally at 300～400 ℃) is failed to utilize well and is diffused in the air, both wasted energy, contaminated environment again, before the utility model, to how to utilize this partly waste heat also reached report in detail.

Summary of the invention task to be solved in the utility model provides a kind of simple in structure, practical, can make full use of the Boiler Steam heating device of waste heat flue gas with vapor (steam) temperature in the further raising jet chimney.

For finishing above-mentioned task, the technical solution adopted in the utility model is: make a square or cuboid or cylindrical flue gas jar earlier, round mouth respectively welds a ring flange at the awl mouth place of hemispherical dome mouth and old name for the Arabian countries in the Middle East's ground round mouth with being connected a hemispherical dome mouth and old name for the Arabian countries in the Middle East at the both ends of this flue gas jar.Steam-heating pipe is made into equidistant being assembled in the flue gas jar of snakelike mark row, with the steam cross over pipe each being arranged snakelike steam-heating pipe connects, the steam inlet pipe penetrates the both sides of flue gas tank skin with steam outlet pipe and is connected with the steam cross over pipe on side, both sides, so constitute the Boiler Steam heating device of a practicality.

Adopt the as above Boiler Steam heating device of technical scheme making, its advantage is simple in structure, and cost of manufacture is low, the vapor (steam) temperature in the steam-heating pipe can be improved 40～60%, reduces fire coal or fuel consume; Because heat energy is fully used, can reduce operating ambient temperature in addition, improve working conditions.

Description of drawings Fig. 1 is the forward structure partial schematic sectional view of Boiler Steam heating device described in the utility model, also is specification digest accompanying drawing of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic

The specific embodiment is described in further detail the specific embodiment of the present utility model below in conjunction with drawings and Examples.

As shown in drawings, 1 is upper flange plate, and 2 is the hemispherical dome mouth, and 3 is steam outlet pipe, and 4 is steam-heating pipe, 4 ' or 41 ' be the steam cross over pipe, 5 is the flue gas jar, and 6 is old name for the Arabian countries in the Middle East's ground round mouth, and 7 is lower flange, and 8 is steam inlet tube.The smoke outlet of square opening 2 is not connected upper flange plate 1 (as welding) with having circularly, hemispherical dome mouth 2 is cone-shaped (as conically shaped body or four cone-shaped), the outlet size of its upper end equates with the center hole of ring flange 1, and the port of the shape of its lower end and flue gas jar 5 is identical and be connected each other.Steam-heating pipe 4 is snakelike shape, and equidistant or not equidistant mark row is assemblied in the inside of flue gas jar 5, and these steam-heating pipe 4 usefulness metal pan boiler tubes are made.The upper end of respectively arranging steam-heating pipe 4 in steam cross over pipe 4 ' connection flue gas jar 5, simultaneously steam outlet pipe 3 and steam cross over pipe 4 ' be connected and communicate.The outer wall that steam outlet pipe 3 passes flue gas jar 5 is installed in the top of flue gas jar 5; The bottom of respectively arranging steam-heating pipe 4 in steam cross over pipe 41 ' connection flue gas jar 5, steam inlet pipe 8 and steam cross over pipe 41 ' be connected, and steam inlet pipe 8 outer wall that passes flue gas jar 5 is installed in the bottom of flue gas jar 5.One of old name for the Arabian countries in the Middle East ground round mouth 6 links to each other with flue gas jar 5, and old name for the Arabian countries in the Middle East the smoke inlet end of round mouth 6 ring flange 7 that is connected.The center hole of ring flange 7 equates with the circular hole of old name for the Arabian countries in the Middle East's ground round mouth 6, and old name for the Arabian countries in the Middle East's ground round mouth 7 also is cone-shaped (as cone shape or four cone-shaped).

During use the Boiler Steam heating device is installed to the top of fire coal or oil burning boiler, make the smoke outlet of ring flange 7 facing to boiler, to enter steam inlet tube 8 from the steam that water-tube boiler gushes out with tube connector, steam from steam inlet tube 8 be introduced into steam cross over pipe 41 ', since the bottom of each row's steam-heating pipe 4 all with steam cross over pipe 41 ' communicate, so enter each steam-heating pipe 4 again again from steam cross over pipe 4 ' compile the back to be transported to required place by steam outlet pipe 3 from the steam of steam cross over pipe 41 ' come out.The waste heat flue gas (temperature is generally about 300 ℃) that comes out from boiler furnace is full of whole flue gas jar 5 after smoke inlet enters in the flue gas jar 5, surround each steam-heating pipe 4 simultaneously and heat is passed to each steam-heating pipe 4 vapor (steam) temperature in each steam-heating pipe 4 is raise.Flue gas in flue gas jar 5 flows again simultaneously, and the flue gas after temperature reduces is overflowed from the exhanst gas outlet of hemispherical dome mouth 2, reaches intensification described in the utility model and energy-conservation purpose.

After one period service time, the Boiler Steam heating device pulled down from boiler clean, remove the dust of flue gas jar 5 and the dirt on the steam-heating pipe 4, reinstall use.
