Description
Technical field
The present invention relates to a kind of steel industry TRT cluster spring support, is specifically related to a kind of cluster spring holder device for steel mill TRT or BPRT energy-saving and power generation device.
Background technique
TRT---(Blast Furnace Top Gas Recovery Turbine Unit, hereinafter referred to as TRT) blast-furnace top gas recovery turbine generator, utilize the by-product of blast furnace process---the pressure energy that top gas has and heat energy, make coal gas by turbine engine expansion work, be translated into mechanical energy, drive a kind of secondary energy recovering device of generator or the generating of other devices.This device had both reclaimed the energy that reducer unit is released, purify again coal gas, reduce noise, stablize furnace top pressure, improve the condition of blast fumance, do not produce any pollution, can realize nuisanceless generating, be the energy-saving environmental protection device that the modern times are international, domestic iron and steel enterprises is generally acknowledged.
BPRT system is the Energy recovery machine set of blast furnace blower and Gas Turbine driven by two energy sources.After BPRT unit is installed, pressure energy and heat energy that top gas has can not only be reclaimed, reduce the hydrodynamic noise of gas distribution pipe network, and by adopting the BPRT systems technology with the leading level in the world to carry out high intelligent control to blast furnace top pressure, blast furnace blower, Gas Turbine, blast furnace top pressure can be raised, increase the mass flow rate of blast furnace air-supply, thus improve the rate of driving of blast furnace, improve output.
Blast furnace is the visual plant of iron and steel enterprise, and its Main Function is manUfaCtUre of pig iron.The iron-smelting furnace charge be made up of iron ore, coke and addition in stove, after high temperature air is blasted blast furnace by blower, through series of chemical, the molten iron of fusing is discharged bottom blast furnace, its top then transfers out a large amount of blast furnace gases, obtain cleaner blast furnace gas through gravitational dust collection, cyclone dust removal and dry type (or wet type) cleaning coal gas technique, then enter low-pressure gas pipe network for user through reducer unit.
Along with blast furnace more and more trends towards maximizing and high pressure furnace roof, needed for blast furnace, energy consumption is also increasing, in addition again because original furnace top pressure is controlled by reducer unit, Gu Ding pressure is higher, the energy that reducer unit is wasted is also more, the noise produced is also larger, larger to the pollution level of environment.TRT or BPRT converts the pressure energy of the original blast furnace gas of loss on reducer unit in vain to mechanical energy with turbo-expander, by generator, mechanical energy is become power delivery to electrical network again, the energy equivalence of TRT recovery is according to statistics in about 1/3rd of blast furnace air energy consumption.The feature of this device is: do not consume any fuel, is the pollution that abates the noise, and non-harmful most economical power generating equipment can replace reducer unit modification stability furnace top pressure.As can be seen here, TRT or BPRT had both had significant economic benefit, had again obvious environmental protection, social benefit, was therefore applied as great power-saving technology by each iron and steel enterprise.
In TRT or BTRT device, inlet/outlet gas pipe line and turbine engine adopt square flange bolt to be connected, and the quality that it is installed directly has influence on the safe operation of turbine set.When inlet/outlet gas pipe line connects with turbine engine, the weight of bend pipe, reducing circumference pipe etc. must not act on turbine engine, and the active force that the expansion joint on gas pipe line must produce expanding with heat and contract with cold is eliminated, and absolutely not allows to act on turbine set.
Import Gas pipe level is arranged, at turbine engine below by 90 degree of bend pipes, enters turbine engine in a vertical manner.Vertical pipeline section is provided with FlexbleJoint, in order to absorb horizontal pipeline section x to displacement of expanding with heat and contract with cold, vertical pipeline section z to displacement of expanding with heat and contract with cold, elbow x to z to displacement of expanding with heat and contract with cold.These 90 degree of elbows are support below, support vertical pipeline section, compensator, elbow and the weight of part of horizontal section and the elastic reaction of FlexbleJoint.
Export coal feed channel is drawn downwards from turbine engine in a vertical manner, be generally rectangular duct, at turbine engine below by 90 degree of bend pipes, become horizontal pipe, vertical pipeline section is provided with FlexbleJoint, in order to absorb horizontal pipeline section x to displacement of expanding with heat and contract with cold, vertical pipeline section z to displacement of expanding with heat and contract with cold, elbow x to z to displacement of expanding with heat and contract with cold.These 90 degree of elbows are support below, support vertical pipeline section, compensator, elbow and the weight of part of horizontal section and the elastic reaction of FlexbleJoint.
The following support of inlet/outlet elbow is except the weight of bearing vertical pipeline section, compensator, elbow and part of horizontal section and FlexbleJoint elastic reaction, also want the x of adaptation level pipeline to displacement, the z of displacement downward vertically of vertical pipe and elbow, ensure the pipeline weight and the elastic reaction that support top all the time, so spring bracket and sliding support must be arranged, for reducing the force of sliding friction be always used on turbine engine, also sliding support should be made to obtain the coefficient of sliding friction as far as possible little.
Due to cannot rigid support be adopted below turbine engine inlet/outlet pipeline, spring bracket cold conditions and hot lower to support all the time as flexible member above weight and counter-force, thus ensure not increase extra normal load to turbomachinery equipment.Horizontal pipe, when producing horizontal thermal walking, can produce sliding-frictional resistance and act on turbine engine, and swiftly flowing coal gas promotes the promotion of turbine engine and large blower, and air-flow is run in the mode of turbulent flow.The pulsation of pressure and the imbalance caused due to blade and rotating shaft foozle, alignment error are rotated and are made turbine housing and peripheral conduits very easily produce vibration, especially, when crossing over critical speed of rotation, system may produce the low-frequency vibration that turbine engine can not bear.Have a strong impact on the working life of the equipment such as expensive turbine engine, even normally cannot run generating continuously.This situation repeatedly occurs in steel mills such as Chengde Iron & Steel Corp. TRT device, Tangshan Bao Tai Iron And Steel Company BTRT device, Ma'anshan Iron and Steel Corp second iron works TRT devices.
