Description

Pipeline heat absorption impact vibration damper of ultrahigh pressure steam small hole injection emptying silencer

Technical Field

Generally, the flow velocity in a pipe is proportional to the noise level, the higher the flow velocity, the higher the noise; the emptying exhaust noise is also called injection noise and is a prominent pollution source; such as power plant boiler steam exhaust, blast furnace air discharge in the metallurgical industry, and high-speed airflow discharge in the chemical industry and other industrial and mining enterprises, all belong to fluid jet noise; the noise source has the characteristics of high sound power for generating noise, high exhaust pressure and high airflow speed, and cannot be applied to general 'silencers'.

The installation behind large-scale superhigh pressure steam or gas safety valve, or power release valve: chinese patent publication No. < CN303775058S ultrahigh pressure steam/gas discharging composite muffler >; or Chinese patent publication No. CN 110556090A ultrahigh pressure steam/gas discharge orifice injection throttling decompression composite emptying muffler, which is also referred to as the following for short: the silencer can be arranged on a pipeline close to the downstream side of the valve, the silencer can be additionally arranged on a pipeline close to the downstream side of the valve to share a part of pressure drop of the valve, and the silencer can play a role of resistance noise elimination by adopting multi-level diffusion buffering and emptying, so that the purpose of reducing the noise of a pipeline system can be achieved by arranging multi-level small-hole injection throttling and pressure reduction behind (namely, downstream) the high-noise valve, and the noise reduction is generally up to or over 60dB (A).

The problems that the multi-level small hole injection throttling decompression emptying of the silencer acts on a bracket of an installation base seat, the recoil force of the silencer acting on the bracket of the installation base seat, the pipeline absorbing heat displacement and the like are also considered while the problems that the large silencer in the form needs to be designed for drainage and the like are solved; the device is mainly used for reducing the exhaust noise of power generation boilers, industrial boilers, superheaters, reheaters, start separators, safety valves and the like with various parameters; or for reducing the process gas emission or venting noise of pressure tanks, ejectors, chemical reactors and other equipment and vessels in the industrial sector of chemical engineering, metallurgy, transportation and the like.

The large silencer in the form can be matched with a safety valve of a boiler or a pressure vessel for use, and a good noise reduction effect is achieved; it can satisfy super high pressure high temperature parameter boiler or pressure vessel relief valve steam extraction noise elimination needs { promptly: exhaust noise of power generation boilers, industrial boilers, superheaters, reheaters, start separators, safety valves and the like which can be used for reducing various parameters }; meanwhile, the method can also be applied to reducing the process gas emission or emptying noise of equipment and containers such as pressure tanks, ejectors, chemical reactors and the like in industrial departments such as chemical industry, metallurgy, transportation and the like, has small resistance, and does not influence the discharge capacity of the safety valve and the working condition of the jump-back seat; the inlet pipe of the silencer is connected with the steam/gas outlet of the steam/gas exhaust device, and the exhausted steam/gas is exhausted to the atmosphere after the noise of the silencer is reduced.

The silencer is connected with a steam/gas exhaust pipe orifice to form a vertical structure, and the silencer and a steel structure truss fixed outside a furnace top chamber are as follows: the pipe heat absorption impact vibration damper of the ultrahigh pressure steam small hole injection emptying silencer needs to consider the problems of impact stress, pipe heat absorption displacement motion and the like { for example, when the length of a steam exhaust pipe behind a safety valve (or a power release valve) of a boiler or a pressure container exceeds 8m, the heat absorption displacement motion when emptying needs to be considered }, the installation of the pipe heat absorption impact vibration damper of the silencer is adopted, a connector pipe of the silencer and an outlet of a steam exhaust/gas pipe of the boiler or the pressure container adopt a direct welding structure, and the horizontal and vertical displacement motion of the steam exhaust/gas pipe is not limited- — the safety that the steam exhaust/gas pipe can be freely and independently fixed by longitudinal and transverse impact response can be adopted, the vertical and horizontal heat absorption displacement of the steam exhaust/gas pipe can be absorbed, so that the steam exhaust/gas pipe is not subjected to additional load due to the installation of the silencer, the safety and reliability of the steam exhaust/gas pipeline under the free working state of heat absorption displacement impact response can be ensured; small volume, light weight, simple structure and convenient maintenance.

Secondly, the pressure drop can be properly distributed, and when the main regulating valve generates strong noise due to large pressure drop, the muffler shares the pressure drop of the main regulating valve by adopting five-layer diffusion buffer emptying small-hole injection throttling and pressure reduction; when the main regulating valve has certain opening to cause pipeline resonance, the multi-stage diffusion buffering emptying silencer is used on the pipeline at the downstream side of the valve, so that the pipeline resonance can be avoided; the opening and closing pressure of the setting safety valve of the muffler, which does not influence the discharge capacity of the safety valve and the starting and bouncing pressure and the recoil pressure, is ensured; and after the phenomena of no abnormity, good tightness and no air leakage during the setting of the boiler safety valve are ensured, the thermal state setting of the safety valve is finished.

Thirdly, the safety is good, and because of adopting the structure that the large-scale silencer of this form and blast pipe are directly welded, the reaction force is balanced each other when the steam/gas discharges, it will adopt the support and silencer to be fixed on the steel structure truss outside the furnace roof, it compares with the structure that pipeline and silencer peg graft, has improved the safe reliability.

Background

The boiler and the pressure vessel are widely applied to industry and people life, and are indispensable production devices and living equipment for industrial production and people life; the boiler or the pressure container is filled with inflammable, explosive and toxic media which often work under ultrahigh pressure and high temperature, and serious personal injuries and deaths and great property losses can be caused once accidents occur.

Boilers and pressure vessels hold an important position in national economy; the boiler is an energy conversion device, chemical energy of fuel is converted into heat energy through fuel combustion in the boiler, the heat energy is transmitted to a working medium, namely water, through heat transfer, and the water is converted into steam or water with higher temperature; in short, a boiler is a device that produces steam or heats water; the boiler for producing steam is called as steam boiler; a boiler that heats water to raise the temperature but does not vaporize is called a hot water boiler; pressure vessels broadly refer to sealed vessels that are subjected to fluid pressure.

The large silencer in the form also belongs to a pressure container bearing ultrahigh pressure fluid, and is a novel device for silencing and reducing noise, which is used for steam/gas emptying, air separation devices, pressure tanks, ejectors, rocket launching jets and the like (comprising boiler superheater steam exhaust, reheater steam exhaust, safety valve or power release valve steam exhaust) and other gas exhaust in the industries of chemical industry, petroleum, metallurgy, thermal power generation, nuclear power, textile, machinery, ultralow-noise aircrafts and the like.

The safety importance of the boiler or the pressure vessel, the working conditions of the boiler and the pressure vessel are severe, and the occurrence of accidents easily is shown as follows: the steam-water system of the boiler is composed of a sealed container and a pipeline, bears medium pressure and flame heating in work, and sometimes bears high pressure and temperature; the pressure is easy to bear pressure loads and other loads with different sizes, and some containers also operate under the conditions of high temperature or deep cooling; the pressure in the boiler, the pressure vessel may be rapidly increased due to an operational error or a reaction abnormality, thereby causing overpressure rupture of the pressure-bearing member; local stress is relatively complex, namely a boiler and a pressure container are generally provided with perforated connecting pipes or discontinuous structures with other shapes, and high stress exists in the local areas, so that a pressure-bearing part can be cracked under unfavorable use environments or load conditions; continuous operation is not easy to inspect, namely, most boilers and pressure vessels are of steel welding structures, and missing inspection defects or standard allowable defects are often hidden in welding seam parts; in use, the boiler and a plurality of pressure vessels must continuously operate, so that the shutdown and the inspection are inconvenient, and the boiler and a plurality of pressure vessels are often broken due to defect expansion; contacting with a corrosive medium … … ….

Under the influence of the above factors, even if the boiler and the pressure vessel with the quality meeting the standard are designed and manufactured, various accidents often occur, not to mention the equipment with the design and manufacture defects; the accident rate of the boiler and the pressure vessel is generally expressed by the number of accidents of ten thousand devices per year, namely: accident/(ten thousand years).

The boiler and the pressure container have serious accident consequences, and the explosion is catastrophic; the fracture and the damage of the pressure-bearing part of the boiler or the pressure container have huge destructive power, which not only damages the equipment, but also damages the surrounding equipment and buildings, often causes the personal casualty, and has extremely important consequences; the main factors causing injury are: firstly, the medium in the boiler and the pressure container is generally gas, liquefied gas or high-temperature liquid with higher pressure, and once the pressure-bearing part is broken, the medium is decompressed and expanded or instantaneously gasified (vaporized), and great energy is instantaneously released; wherein 85% of energy is used for generating shock waves which are rapidly transmitted to the periphery, so that equipment and buildings are damaged, and personal safety is harmed; if the pressure of the pressure source reaches 0.1MPa, people within 1m from the pressure source can die; secondly, when the fragments hurt people or break down equipment, buildings, namely boilers or pressure containers, some shells can be broken into fragments and fly out at high speed, and the encountered equipment or buildings are broken down and crashed, so that people are directly hurt sometimes; thirdly, the medium in the container overflows to cause poisoning, burning and secondary explosion to generate chain reaction; … … are provided.

In conclusion, the boiler and the pressure vessel are widely applied, the working condition is severe, the boiler and the pressure vessel are easy to damage and have accidents, and the accident consequence is serious, so that the safety of the boiler and the pressure vessel cannot be looked at in an idle mode; as in other countries in the world, the boiler and the pressure vessel are used as special equipment, and the safety of the boiler and the pressure vessel is checked and supervised by special institutions.

The effective realization of the way of the boiler and the pressure vessel accidents for years proves that the basic way of avoiding the boiler and the pressure vessel accidents is as follows: firstly, using a law to guide the design, manufacture, installation, use, inspection, repair, reconstruction and other links of a boiler and a pressure container; safety technical supervision regulations of steam boilers, hot water boilers, pressure vessels, gas cylinders and the like are formulated or revised in China in succession; various design and manufacture standards of boilers and pressure vessels are promulgated by the country and relevant departments; for example, GB150 pressure vessel, GB9222 calculation of strength of pressed elements of water tube boilers, GB/T16508 calculation of strength of pressed elements of boiler shell boilers, etc.; practice proves that the accidents of the boiler and the pressure vessel can be effectively avoided by designing, manufacturing, installing, using, inspecting, repairing, transforming and the like of the boiler and the pressure vessel strictly according to relevant laws and regulations and standards; and executing official or third party supervision.

The safety technology of boilers and pressure vessels is a system safety engineering technology taking equipment safety as a center; accidents of boilers and pressure vessels, particularly boiler or pressure vessel explosions, are the result of the instantaneous release of energy as a result of the rupture of pressure-bearing energy storage equipment; the device is ensured not to be broken in the pressure-bearing energy storage process, and the safety problems of boilers and pressure vessels are fundamentally solved; the boiler and the pressure container are burst and exploded for two reasons: firstly, the working conditions are seriously deteriorated and far exceed the designed working conditions, such as serious overpressure or overtemperature; secondly, the equipment has hidden or generated defects, so that the equipment cannot bear normal design working conditions; accordingly, countermeasures to avoid a burst explosion: firstly, the selected materials and equipment meet the requirements of normal working conditions; secondly, the deterioration of working conditions is avoided; thirdly, the defects of the equipment are prevented and eliminated; meanwhile, the method is not easy, and not only relates to the safety performance of the boiler and the pressure vessel equipment, but also relates to related accessories, auxiliary machines, personnel and environment; the basic structures and the working principles of boilers and pressure vessels need to be mastered, a series of knowledge for ensuring safety also needs to be known, and the knowledge relates to multiple subjects of mathematics, material mechanics, hydromechanics, thermodynamics, metallology, heat treatment, chemistry, management and the like, and has stronger comprehensiveness and practicality; as long as the knowledge about each subject is comprehensively applied consciously, the basic boiler and pressure vessel safety technology can be mastered gradually, gradually accumulated and combined with the theory and practice.

A safety valve: the valve is a safety protection valve for preventing overpressure of a boiler and a pressure container, and is automatically opened or closed according to the working pressure of the boiler and the pressure container; the safety valve has the advantages that when the boiler and the pressure container work under the normal pressure condition, the boiler and the pressure container are kept in a closed state; when the pressure of the medium in the container exceeds the set pressure, the container can be automatically opened under the pushing of the pressure of the medium, so that the container is decompressed, and the container or a pipeline is prevented from being damaged due to overpressure; when the medium pressure in the container is reduced to a normal value, the medium pressure can be automatically closed and stop releasing, so that the pressure in the container is always kept within a highest allowable range, the boiler and the pressure container are protected from normal operation, and accidents are prevented; therefore, the safety valve is widely applied to various pressure containers and pressure pipelines; in the safety relief device, the safety valve can be automatically closed after being opened to discharge over-high pressure, and the container and the device can be continuously used, … ….

Just as, add the vertical installation formula silencer on the downstream pipeline behind the main steam system relief valve door of large-scale boiler superhigh pressure (namely on boiler superhigh pressure residual steam or gas exhaust tail pipe export pipeline), be fixed in on the basic vibration isolation bracket of muffler on the outdoor steel construction truss of furnace roof, adopt: the installation of the pipeline heat absorption impact vibration damper of the ultrahigh pressure steam pinhole injection emptying silencer, wherein an inlet connecting pipe of the silencer and an outlet of a steam exhaust pipe of a boiler pressure container adopt a direct welding structure, and the horizontal and vertical heat absorption displacement impact response of the steam exhaust pipe is not limited freely, namely the silencer can be longitudinally and transversely fixed independently, and can absorb and isolate the vertical heat displacement and the horizontal displacement of the steam exhaust pipeline, so that the steam exhaust pipeline is not subjected to additional load due to the installation of the silencer, and the reliable safety of the steam exhaust/gas pipeline in the heat absorption displacement state can be ensured; the opening and closing pressure of the setting safety valve which does not influence the discharge capacity, the starting jump and the recoil pressure of the safety valve is ensured; the thermal state setting of the safety valve is finished after the boiler safety valve is set without abnormity, good tightness and no air leakage phenomenon.

Shock absorber/device principle: one or more free masses which play a role of impact are arranged on a vibrating body by utilizing the energy loss principle after two objects collide with each other, and when a system vibrates, the free masses repeatedly impact the vibrating body to consume the vibration energy so as to achieve the aim of vibration reduction, namely the principle of an impact damper/device; the shock absorber (device) has the advantages of simple structure, light weight, small volume, capability of being used in a larger frequency range and the like.

Impact isolation: when the equipment is subjected to impact excitation caused by collision, hammer forging, shaking, falling, explosion and the like, the force, displacement, speed and acceleration of the equipment are changed rapidly; the work of the device can be disabled and even damaged, the impact is transmitted to the foundation, and surrounding equipment and the foundation can be damaged; for this purpose, shock isolation is performed.

Impact isolation principle: shock is a transient excitation suddenly added to the system, with the action period much shorter than the natural period of the system; the impact isolation is to store the energy input into the system in a rapid way through the deformation of the impact isolator (device) in the process of releasing, converting and transmitting the impact energy, then release the energy stably in a time which is several times longer than the inherent cycle through the free vibration of the system, and consume part of the energy by the damping of the impact isolator (device); the sharp shock wave acts on equipment or foundation in a milder mode so as to reduce the damage of the shock; since the shock contains various frequency components, the vibration transmissibility useful for simple harmonic vibration cannot be used to isolate the calculation; in addition, since the impulse excitation is simplified into rectangular pulses, the self-power spectral density function is also a transcendental function, and the analytic expression of the difference of the impulse response is difficult to obtain; therefore, random isolation methods cannot be used, and impact isolation calculations are necessary; impact isolation is also divided into active and passive isolation, and single-degree-of-freedom and multi-degree-of-freedom isolation; the impact excitation function is generally divided into two categories, namely a step type and an impulse type; generally expressed in terms of its peak, duration and waveform; and performing isolation calculation according to the motion rule of the isolation system under the impact action.

Passive isolation of the impact: passive isolation is used to mitigate the effects of basic motion caused by external impacts on the machine equipment to reduce stress and strain in the equipment; passive isolation of the impact should meet the following requirements, namely: the maximum vibration quantity or the maximum force transmitted to protected equipment (or a part of the equipment) through the isolator (device) is smaller than an allowable value, and the safe operation of the isolated equipment is ensured; and secondly, the maximum deformation amount of the isolator (device) is smaller than the allowable value, so that the isolator (device) obtains enough space.

Rubber products: the main characteristics are as follows: the bearing capacity is low, the damping coefficient is 0.15-0.3, the elastic deformation is large, and the creep effect is achieved; the rigidity in three directions can be freely selected; the application range is as follows: the vibration isolation device is mainly used for active vibration isolation; when the load is large, the bearing type is made, and when the load is small, the bearing type is made; the metal spring is matched with the metal spring for use, so that the high-frequency vibration isolation effect is good; note that: the pressure bearing mode ensures that the rubber freely expands to the periphery, the relative deformation is controlled to be 10-20%, and the section of the bearing shear type is designed to be rhombic; the rubber should be protected from sun exposure and oil and water erosion, and should not be pulled.

A metal spring: main characteristics: the bearing capacity is high, the elastic deformation is large, and the damping coefficient is 0.01; the horizontal rigidity is smaller than the vertical rigidity, and the swing is easy; (II) application range: the active vibration isolation device is used for passive vibration isolation and active vibration isolation of large-excitation-force equipment; the vibration isolation device is easy to shake and is not suitable for vibration isolation of precision equipment; (III) attention points: when greater damping is desired, a damper may be added or used in conjunction with a material (e.g., rubber) having greater damping.

And when the amplitude of the support motion displacement is known, dynamic parameter design of vibration isolation can be carried out according to the amplitude of the motion displacement allowed by mechanical equipment, and the like.
