Description

Technical Field

[0001] Generally speaking, the flow velocity in the pipe is proportional to the noise level. The higher the flow velocity, the greater the noise. Venting exhaust noise is also called injection noise, which is a prominent pollution source. For example, the exhaust of boilers in power plants, the blast furnace venting in the metallurgical industry, the high-speed airflow emissions in the chemical industry and other industrial and mining enterprises are all fluid injection noise. The characteristics of this type of noise source are that the sound power of the noise is large, the exhaust pressure and airflow velocity are both very high, and the general "muffler" can no longer be used.

[0002] The present invention relates to a pipeline heat absorption shock vibration reduction device for an ultra-high pressure steam small hole injection venting silencer. When the maximum amplitude of the movement displacement of the basic impact response bracket of the silencer is known, the pipeline heat absorption shock vibration reduction device of the silencer is manufactured in an integrated manner by adopting a structural form of vibration isolation, vibration reduction and vibration elimination dynamic parameter design and other measures according to the allowable value of the movement displacement amplitude allowed by the mechanical equipment.

[0003] Installed behind a large ultra-high pressure steam or gas safety valve (or power release valve): Chinese Patent Publication No. CN303775058 S <Ultra-high pressure steam / gas discharge composite silencer>; or Chinese Patent Publication No. CN110556090 A <Ultra-high pressure steam / gas discharge small hole injection throttling pressure reduction composite venting silencer> - hereinafter referred to as "silencer", the above-mentioned "silencer" can be installed on the pipeline close to the downstream side of the valve, and the addition of a "silencer" on the downstream pipeline of the valve can also be used to share part of the pressure drop of the valve, and the multi-level diffusion buffer venting "silencer" itself plays a resistant silencing role, so the multi-level small hole injection throttling pressure reduction is set behind the high-noise valve (i.e.: downstream) to achieve the purpose of reducing the noise of the pipeline system, and the general noise reduction reaches or exceeds 60dB (A).

[0004] The above-mentioned large-scale "muffler" should be designed with drainage and other issues, and the effect of the multi-level small hole injection throttling pressure reduction and venting of the "muffler" on the installation base bracket and the heat absorption displacement of the pipeline should also be considered; it is mainly used to reduce the exhaust noise of various parameters of power generation boilers, industrial boilers, superheaters, reheaters, start-up separators and safety valves; or to reduce the emission or venting noise of process gases from pressure tanks, ejectors, chemical reactors and other equipment and containers in industrial sectors such as chemical, metallurgy, and transportation.

[0005] The above-mentioned large-scale "silencer" can be used in conjunction with boiler or pressure vessel safety valves to achieve good noise reduction effects; it can meet the exhaust silencing needs of ultra-high pressure and high temperature parameter boilers or pressure vessel safety valves {i.e., it can be used to reduce the exhaust noise of power generation boilers, industrial boilers, superheaters, reheaters, start-up separators and safety valves of various parameters}; it can also be used to reduce the emission or venting noise of process gases from pressure tanks, ejectors, chemical reactors and other equipment and containers in industrial sectors such as chemical, metallurgical, and transportation. It has low resistance and does not affect the displacement and starting and returning conditions of the safety valve; the inlet pipe of this type of "silencer" is connected to the exhaust / gas pipe port of the exhaust / gas device, and the discharged steam / gas is discharged to the atmosphere after noise reduction through the "silencer".

[0006] This type of "silencer" is connected to the exhaust steam / gas pipe outlet as a vertical structure, and the "silencer" is fixed to the steel structure truss outside the furnace top: the pipe heat absorption shock vibration reduction device of the ultra-high pressure steam small hole injection venting silencer should consider the impact stress and pipe heat absorption displacement movement and other issues {for example, when the length of the steam pipe behind the safety valve (or power release valve) of the boiler or pressure vessel exceeds 8m, the heat absorption displacement movement during venting should be considered}, and the above "pipe heat absorption shock vibration reduction device of the silencer" is installed. The interface pipe of the "silencer" and the exhaust steam / gas pipe outlet of the boiler or pressure vessel adopt a direct welding structure, and the horizontal and vertical displacement movement of the exhaust steam / gas pipe is not restricted-it can be fixed independently for safety in longitudinal and lateral impact response freedom, and can absorb the vertical and horizontal heat absorption displacement of the exhaust steam / gas pipeline, so that the exhaust steam / gas pipeline is not subjected to additional load due to the installation of the "silencer", which can ensure the safety and reliability of the exhaust steam / gas pipeline working in the free state of heat absorption displacement impact response; small size, light weight, simple structure and easy maintenance.

[0007] Secondly, the pressure drop can be properly distributed. When the main regulating valve generates strong noise due to the large pressure drop, the "muffler" adopts a five-level diffusion buffer venting small hole injection throttling pressure reduction to share the pressure drop of the main regulating valve; when a certain opening of the main regulating valve will cause pipeline resonance, a multi-level diffusion buffer venting "muffler" is used on the pipeline on the downstream side of the valve to avoid pipeline resonance; and ensure that this type of "muffler" does not affect the safety valve displacement and the setting of the safety valve opening and closing pressure of the start-up and return seat pressures; after ensuring that the boiler safety valve is set without abnormalities, good tightness, and no air leakage, the hot setting of the safety valve is completed.

[0008] Third, it has good safety. Since this type of large "muffler" and exhaust pipe are directly welded, the reaction forces are balanced when steam / gas is discharged. It will use supports and "muffler" to fix on the steel structure truss outside the furnace top room. Compared with the structure of pipe and "muffler" plug-in connection, it improves safety and reliability. Background Art

[0009] Boilers and pressure vessels are widely used in industry and people's lives. They are indispensable production devices and living equipment for industrial production and people's lives. Boilers or pressure vessels contain flammable, explosive, and toxic media and often work under ultra-high pressure and high temperature. Once an accident occurs, it will cause serious personal injury and death and significant property losses.

[0010] Boilers and pressure vessels occupy an important position in the national economy. A boiler is an energy conversion device that converts the chemical energy of the fuel into thermal energy through fuel combustion in the boiler, and then transfers the thermal energy to the working medium - water through heat transfer, turning the water into steam or water at a higher temperature. In short, a boiler is a device that produces steam or heats water. A boiler that produces steam is called a steam boiler. A boiler that heats water to raise its temperature but does not vaporize it is called a hot water boiler. A pressure vessel generally refers to a sealed container that withstands fluid pressure.

[0011] This type of large "muffler" is also a pressure vessel that can withstand ultra-high pressure fluids. It is used for steam / gas venting in the chemical, petroleum, metallurgy, thermal power generation, nuclear power, textile, machinery, ultra-low noise aircraft and other industries, as well as air, air separation units, pressure tanks, ejectors, rocket launch jets, etc. (including: boiler superheater exhaust, reheater exhaust, safety valve or power release valve exhaust) and other gas emissions. It is a new type of silencing and noise reduction device.

[0012] The importance of boiler or pressure vessel safety. Boilers and pressure vessels work in harsh conditions and are prone to accidents. The specific manifestations are: ① Bearing ultra-high pressure and temperature - the steam-water system of the boiler is composed of sealed containers and pipes. It bears medium pressure and flame heating during operation. Sometimes the pressure and temperature it bears can reach very high levels; the pressure is easy to bear pressure loads and other loads of different sizes, and some containers are also operated under high temperature or deep cold conditions; the pressure in the boiler and pressure vessel may rise rapidly due to operating errors or abnormal reactions, resulting in overpressure rupture of the pressure-bearing parts; ② Local stress is relatively complex - boilers and pressure vessels usually have open-hole pipes or other discontinuous structures of other shapes. There are high stresses in these local areas, which will cause the pressure-bearing parts to rupture under unfavorable use environments or load conditions; ③ Continuous operation is not easy to inspect - boilers and pressure vessels are mostly steel welded structures, and there are often hidden missed defects or standard allowed defects in the welds; during use, boilers and many pressure vessels must operate continuously, which is inconvenient to stop for inspection, and often ruptures due to the expansion of defects;

[0013] ④Contact with corrosive media——……

[0014] Under the combined influence of the above factors, various accidents often occur even for boilers and pressure vessels whose design and manufacturing quality meet the standards, not to mention equipment with design and manufacturing defects; the accident rate of boilers and pressure vessels is usually expressed as the number of accidents occurring per year for 10,000 units of equipment, that is: accidents / (10,000 units·year).

[0015] Accidents with boilers and pressure vessels have serious consequences, and their explosions are catastrophic. The rupture and destruction of the pressure-bearing parts of boilers or pressure vessels has great destructive power, which not only damages the equipment itself, but also damages the surrounding equipment and buildings, and often causes casualties, with extremely serious consequences. The main factors causing injuries are: ① Shock waves destroy equipment, buildings or directly injure people - the medium in boilers and pressure vessels is generally gas, liquefied gas or high-temperature liquid with high pressure. Once the pressure-bearing parts are broken, the medium will be depressurized and expand or instantly gasify (vaporize), instantly releasing a lot of energy; 85% of the energy is used to generate shock waves, which spread rapidly to the surroundings, destroying equipment, buildings and endangering personal safety; if the pressure source pressure reaches 0.1MPa, it can kill people within 1m of the pressure source; ② Fragments injure people or penetrate equipment and buildings - when a boiler or pressure vessel ruptures, some shells may break into fragments and fly out at high speed, penetrating and damaging the equipment or buildings they encounter, and sometimes directly injuring people; ③ The medium in the container overflows, causing poisoning, combustion, secondary explosion, and chain reactions; ...

[0016] In summary, boilers and pressure vessels are widely used, work in harsh conditions, are easily damaged and accidents occur, and the consequences of accidents are serious. Therefore, the safety of boilers and pressure vessels cannot be taken lightly. my country, like other countries in the world, regards boilers and pressure vessels as special equipment, and their safety is inspected and supervised by specialized agencies.

[0017] The ways to avoid boiler and pressure vessel accidents have been proven to be effective over the years. The basic ways to avoid boiler and pressure vessel accidents are: ① Use laws and regulations to guide the design, manufacture, installation, use, inspection, repair, and modification of boilers and pressure vessels; my country has successively formulated or revised safety technical supervision regulations for steam boilers, hot water boilers, pressure vessels, gas cylinders, etc.; the state and relevant departments have promulgated various boiler and pressure vessel design and manufacturing standards; such as GB150 "Pressure Vessel", GB9222 "Strength Calculation of Pressure Components of Water Tube Boilers", GB / T16508 "Strength Calculation of Pressure Components of Shell Boilers", etc.; practice has proved that strictly following relevant laws and regulations and standards for the design, manufacture, installation, use, inspection, repair, and modification of boilers and pressure vessels can effectively avoid boiler and pressure vessel accidents; ② Implement official or third-party supervision.

[0018] Boiler and pressure vessel safety technology is a system safety engineering technology centered on equipment safety; boiler and pressure vessel accidents, especially boiler or pressure vessel explosions, are the result of instantaneous release of energy from the rupture of pressurized energy storage equipment; ensuring that the equipment does not rupture during the pressurized energy storage process fundamentally solves the safety problem of boilers and pressure vessels; boiler and pressure vessel rupture and explosion are nothing more than two reasons: one is that the working conditions seriously deteriorate, far exceeding the design working conditions, such as severe overpressure or overtemperature; the other is that the equipment itself has hidden or generated defects, which makes the equipment unable to withstand the normal design working conditions; accordingly, the countermeasures to avoid rupture and explosion are: first, the selected materials and equipment should meet the requirements of normal working conditions The first is to meet the requirements; the second is to avoid deterioration of working conditions; the third is to prevent and eliminate equipment defects; it is not an easy task to achieve all these points at the same time, which involves not only the safety performance of boilers and pressure vessels themselves, but also related accessories, auxiliary machines, personnel and environment; it is necessary to master the basic structure and working principle of boilers and pressure vessels, and also to understand a series of knowledge to ensure safety, involving mathematics, material mechanics, fluid mechanics, thermodynamics, metallurgy and heat treatment, chemistry, management and other disciplines, with strong comprehensiveness and practicality; as long as we consciously and comprehensively apply the relevant knowledge of various disciplines, proceed step by step, accumulate gradually, and adhere to the combination of theory and practice, it will not be difficult to master the basic boiler and pressure vessel safety technology.

[0019] Safety valve: a safety protection valve to prevent boilers and pressure vessels from overpressure. It automatically opens or closes according to the working pressure of the boilers and pressure vessels. The advantage of the safety valve is that it remains in a closed state when the boilers and pressure vessels are working under normal pressure. When the medium pressure in the container exceeds the specified value, it can automatically open under the push of the medium pressure to release the pressure in the container to prevent the container or pipeline from being damaged due to overpressure. When the medium pressure in the container drops to normal, it can close automatically and stop releasing the pressure, so that the pressure in the container is always maintained within the maximum allowable range, protecting the normal operation of boilers and pressure vessels and preventing accidents. Therefore, safety valves are widely used in various pressure vessels and pressure pipelines. In the above-mentioned safety pressure relief device, the safety valve can automatically close after opening to discharge excessive pressure, and the container and device can continue to be used, etc.

[0020] Just as, a mounted "muffler" is added to the downstream pipeline after the safety valve of the ultra-high pressure main steam system of a large boiler (i.e., on the outlet pipeline of the ultra-high pressure residual steam or gas venting tail pipe of the boiler), and fixed on the basic vibration isolation bracket of the "muffler" on the outdoor steel structure truss of the furnace top, the installation of the pipeline heat absorption shock vibration reduction device of the ultra-high pressure steam small hole injection venting muffler is adopted, the inlet pipe of the "muffler" and the exhaust steam pipe outlet of the boiler pressure vessel adopt a direct welding structure, and the horizontal and vertical heat absorption displacement impact response of the exhaust steam pipe is free and unrestricted - it can be fixed separately in the vertical and horizontal directions, and can absorb and isolate the vertical thermal displacement and horizontal displacement of the exhaust steam pipe, so that the exhaust steam pipe is not subjected to additional load due to the installation of the "muffler", and can ensure the reliable safety of the exhaust steam / gas pipeline working in the heat absorption displacement state; ensure that the safety valve discharge and the setting of the safety valve opening and closing pressure do not affect the safety valve displacement and the starting and returning pressure; after ensuring that the boiler safety valve is set without abnormality, good tightness, and no air leakage, the hot setting of the safety valve is ended.

[0021] The principle of impact vibration absorber / device is to utilize the principle of energy loss after two objects collide with each other, and install one or more free masses that play an impact role on the vibrating body. When the system vibrates, the free mass will repeatedly impact the vibrating body to consume the vibration energy and achieve the purpose of vibration reduction. This is the principle of impact vibration absorber / device; impact vibration absorber (device) has the advantages of simple structure, light weight, small size, and can be used in a larger frequency range.

[0022] Impact isolation: When equipment is subjected to impact excitation caused by collision, forging hammer, shaking, falling, explosion, etc., its force, displacement, velocity and acceleration will change dramatically, which may cause it to fail or even be destroyed. The impact is transmitted to the foundation and may also damage the surrounding equipment and foundation. For this reason, impact isolation is performed.

[0023] Shock isolation principle:

[0024] Shock is a transient excitation that is suddenly added to the system, and its action period is much shorter than the natural period of the system. Shock isolation is to store the energy suddenly input into the system through the deformation of the shock isolator (device) during the release, conversion and transmission of the shock energy, and then release the energy steadily through the free vibration of the system in a time several times longer than the natural period, and also use the damping of the shock isolator (device) to consume part of the energy; so that the sharp shock wave acts on the equipment or foundation in a more moderate form to reduce the harm of the shock;

[0025] Since the shock contains various frequency components, the vibration transmissibility that is useful for simple harmonic vibration cannot be used for isolation calculation; in addition, since the shock excitation is simplified to a rectangular pulse, its self-power spectrum density function is also a transcendental function, and it is difficult to obtain the analytical expression of the difference of the shock response; therefore, the random isolation method cannot be used, and shock isolation calculation is necessary;

[0026] Shock isolation is also divided into active and passive isolation, as well as single-degree-of-freedom and multi-degree-of-freedom isolation; shock excitation functions are generally divided into two categories: step type and pulse type; usually represented by its peak value, duration and waveform; isolation calculations are performed based on the motion law of the isolation system under shock.

[0027] Passive isolation of shock: Passive isolation is used to reduce the impact of foundation movement caused by external shock on machinery and equipment, so as to reduce stress and strain in the equipment; Passive isolation of shock should meet the following requirements, namely:

[0028] (i) The maximum vibration or maximum force transmitted to the protected equipment (or a part of the equipment) through the isolator (device) is less than the allowable value, ensuring the safe operation of the isolated equipment;

[0029] 2. The maximum deformation of the isolator (device) is less than the allowable value, so that the isolator (device) has sufficient space.

[0030] Rubber products:

[0031] ①. Main characteristics: low load-bearing capacity, damping coefficient of 0.15-0.3, large elastic deformation and creep effect; can be made into various shapes, and can freely select the stiffness in three directions;

[0032] ②. Application scope: mostly used for active vibration isolation; when the load is large, it is made into a pressure-bearing type, and when the load is small, it is made into a shear-bearing type; when used in conjunction with metal springs, it has a good effect in isolating high-frequency vibrations;

[0033] ③. Notes: The pressure-bearing type should ensure that the rubber can expand freely in all directions, and the relative deformation should be controlled at 10% to 20%. The cross-section of the shear-bearing type should be designed to be diamond-shaped; the rubber should be protected from sunlight and erosion by oil and water, and should not be subjected to tension.

[0034] Metal spring:

[0035] 1. Main characteristics: high bearing capacity, large elastic deformation, damping coefficient of 0.01; horizontal stiffness is smaller than vertical stiffness, easy to shake;

[0036] (ii)Application scope: used for passive vibration isolation and active vibration isolation of equipment with large excitation force; it is not suitable for vibration isolation of precision equipment due to easy shaking;

[0037] ㈢. Note: When greater damping is required, a damper can be added or used in combination with a material with greater damping (such as rubber).

[0038] After knowing the displacement amplitude of the support movement, the dynamic parameters of the vibration isolation can be designed according to the allowable displacement amplitude of the mechanical equipment. Summary of the invention
