Abstract
The utility model relates to a high temperature gas cooling, residual heat reclamation and generated steam energy efficiency system for the converter, electric furnace, open furnace, and is characterized in that the device comprises a plurality of vapor generators(1) connected in series, with an air circulating section of ladder degression. One ends of the vapor generators(1) are respectively provided with an inlet joint(5), and the other ends are respectively provided with an outlet joint(7). The vapor generators(1) are respectively arranged internally with a heat transfer element(6), and are connected with a vapor drum through their own vapor water. The vapor generation system residual heat generated vapor energy efficient device arranged in the high temperature flue of the new utility model can discharge the high temperature gas decreased from 100 to 180 DEG C, so as to realize the aims of efficient residual heat utilization, and energy efficiency and consumption reduction. The utilization of the vapor generation system can improve the heat transfer efficiency, safety and reliability, with each part of the flow being separately distributed. With the small volume of the equipment, the utility model is convenient for disassembly, daily maintenance, and repair.
Description
Technical field
The utility model utilizes the high-temperature gas cooling liberated heat that produces in converter, electric furnace, the open-hearth process, by the steam generating system of heat pipe, finned tube and heat pipe and finned tube combining structure form, in the generation, low-pressure steam.
Background technology
The method of steel-making mainly adopts converter, electric furnace and three kinds of technologies of open hearth, can produce a large amount of high-temperature gases more than 1000 ℃ in its production process, need cool, and reclaims the beneficiating ingredient in the gas simultaneously.Adopted nature cooling or water cooling form in the past, and needed long flue to increase area of dissipation or consume a large amount of cooling waters, the whole dissipation of heat are reclaimed fully and are utilized, and operating environment on every side is relatively poor.
Summary of the invention
The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of high-temperature gas cooling down heat-recovering steam producing energy conservation device.
The purpose of this utility model can reach by following measure:
A kind of converter, electric furnace, open hearth steelmaking high-temperature gas cooling down heat-recovering steam producing energy conservation system device, it is characterized in that this device comprises that many are in series and its gas communication cross section is the steam generator 1 that staged is successively decreased, one end of steam generator 1 is provided with import interface 5, the other end is provided with discharge coupling 7, be provided with heat transfer element 6 in described steam generator 1, described steam generator 1 links to each other with drum by carbonated drink connecting leg 4 separately.This device is arranged steam generating system from high temperature step by step to the low temperature segmentation, and gas communication cross section staged is successively decreased to reach good heat exchange effect.
The purpose of this utility model can also reach by following measure:
Be in series and a end that its gas communication cross section is the steam generator 1 that staged successively decreases also is connected with water preheater 3 at described many, on described water preheater 3, be provided with discharge coupling 7.
This steam generating system device can adopt and be arranged vertically, or adopts squint to arrange, and with horizontal plane angle 〉=more than 5 degree.
The bottom of described steam generator 1 and water preheater 3 is provided with ash exhauster 8.
Advantage of the present utility model
The utility model energy-saving effect is remarkable, and demineralized water at first absorbs low temperature place heat in the flue, is heated to closely saturatedly, and the heat that absorbs temperature higher position in the flue again is vaporizated into saturated vapor, and last quality steam preferably just is admitted to pipe network.The package unit flow arrangement is reasonable, reclaims the high-temperature gas waste heat by grade, and steam production is big, the steam grade is good, and waste heat recovery rate height has improved the execute-in-place condition simultaneously.
The steam generating system waste heat that the utility model is provided with in high-temperature flue steams in the energy saver, makes that high-temperature gas reaches and effectively utilizes waste heat, energy saving purposes from dropping to discharging below 180 ℃ more than 1000 ℃ in the flue.Use this steam generating system and improved heat transfer efficiency, safe and reliable, the separate dispersed placement in each position of flow process, equipment volume is little, is convenient to dismounting, regular maintenance, maintenance is convenient.
