Background technology
For realizing instrument that multi-form energy changes mutually or device can be commonly referred to as transducer, such as audio electrical signal is converted to heard sound, or heard sound is converted to audio electrical signal, realize the electroacoustics transducer that electric energy and acoustic energy are changed mutually, as loudspeaker (loudspeaker), earphone, microphone etc.Heat interchanger is also known as heat exchanger, also being the one of transducer, having the advantages that augmentation of heat transfer measure heat transmission resistance is little, heat-transfer capability is large, is Appropriate application and the existing energy of saving, the key equipment tapped a new source of energy, the industry such as widespread use drystone oil, chemical industry, medicine, flea product, iron and steel, heat supply.In order to energy-saving and cost-reducing, utilize heat interchanger to carry out waste heat recovery to economize on coal, fuel-economizing, economize on electricity, water saving, joint vapour are the most effective power-economizing method at present.
For industrial site such as large-scale generating plant, steelworkss, have a large amount of production waste heats and follow flue gas discharge, if directly by these fume emissions in air, a large amount of energy dissipations can be caused, therefore, in flue, installing transducer, to carry out residual heat collection be a kind of very effective energy utilization means.Energy converting pipe is arranged in flue by prior art, passes to current in energy converting pipe, by the waste heat of the current collecting flue of tube interior.Flue environment temperature is higher, under normal circumstances drying, high temperature, high flow rate.Because high-speed and high-temperature flue gas makes windward side water pipe wearing and tearing very fast, when seepage trachoma, crack appear in water pipe, inner current ooze out or spray, and vaporize at once under this hot environment, the water smoke of vaporization by the dust deposit in flue gas, thus can cause flue blockage.
For this situation, the invention provides a kind of flue transducer protective device, namely the protection tube by meeting the one side of flue gas to increase by row's redundancy at transducer, water and air is sealed with in protection tube, and have pressure transducer, between redundancy protecting pipe and transducer, installing and measuring network, measuring network for measuring flue interface temperature; In high temperature environments, the water in protection tube will evaporate, and make protection tube internal gas pressure increase, and meanwhile, because water vapor temperature is 100 degrees Celsius, in airtight protection tube, water cannot be vaporized completely; When there is seepage trachoma, crack in protection tube appearance wearing and tearing, protection tube, protection tube is inner due to hyperbaric environment, water vapor and liquid are oozed out, air pressure inside reduces, local temperature is reduced to 100 degrees Celsius by the water vapor simultaneously oozed out and aqueous water, pressure transducer and temperature sensor measure outlier simultaneously, thus accurately judge protection tube abort situation, carry out maintenance in time and remedy; Meanwhile, because the water yield in protection tube is limited, flue blockage can't be caused because moisture flows out in a large number.
Summary of the invention
The object of the invention is to monitor zones of different in flue to the wearing and tearing dynamics of energy converting pipe, avoid energy converting pipe to wear and tear; by monitoring; quick and precisely locate the protection tube position of wearing and tearing, the detection that the position may worn and torn to energy converting pipe is in advance carried out and maintenance, avoid because energy converting pipe wearing and tearing cause flue blockage.
For this reason; measuring and protecting pipe, the sealing-plug be installed on redundancy protecting pipe, the first sensor be installed on sealing-plug, the trepanning be positioned on measuring and protecting pipe the invention provides a kind of flue transducer protective device, comprise redundancy protecting pipe, being fixed by connecting band and redundancy protecting pipe, be installed on the protective sleeve on measuring and protecting canister aperture and be arranged on the second sensor of protective sleeve.
Described redundancy protecting pipe is the tubular structure of sealing, and inside is filled with a certain amount of water and air, and at ambient temperature, air pressure inside is identical with atmospheric pressure; Redundancy protecting pipe there is sealing-plug, water and air is sealed in redundancy protecting pipe inner; Described first sensor is pressure transducer, and pressure transducer is arranged on sealing-plug, is positioned at redundancy protecting pipe inner, contacts with the air in redundancy protecting pipe; The electrical cable of pressure transducer is connected with server by sealing-plug.
Described measuring and protecting pipe is fixed on redundancy protecting pipe by connecting band, and has certain space between redundancy protecting pipe; Measuring and protecting pipe has trepanning, and trepanning is for installing protective sleeve, and size and the protective sleeve of trepanning match; Described protective sleeve is for the protection of the second sensor, and the second sensor is temperature sensor, and protective sleeve is the structure of a hollow, and protective sleeve adopts the good metal material of thermal conductivity to make; Temperature sensor utilizes the good material of the thermal conductivity such as heat conductive silica gel to be fixed on the inside of protective sleeve, and the electric wiring of temperature sensor is connected with server by the inside of measuring and protecting pipe.Measuring and protecting Guan Shangjun be distributed with multiple trepanning, for installing multiple sensor.
Above-mentioned a kind of flue transducer protective device, described protective sleeve is the screw of a hollow structure, described trepanning be one with the screw of described screw mates, screw adopts Steel material to make, Steel material has good thermal conductivity, and commercially ample supply and prompt delivery, and price is relatively cheap, is convenient to processing; Certainly, other metal materials such as such as aluminium, copper or silver can also be adopted.
Beneficial effect of the present invention: by redundancy protecting pipe, can avoid transducer to be directly subject to the impact of flue smog, protection transducer; Simultaneously, redundancy protecting pipe adopts special design, by water and air and the pressure transducer for measuring of sealing, the abrasion condition of redundancy protecting pipe can be measured rapidly, simultaneously by the temperature sensor on measuring and protecting pipe, accurately can locate the position of wearing and tearing, thus make a response rapidly, avoid working long hours and cause energy converting pipe to wear and tear; Because the water yield in redundancy protecting pipe is certain, can't occur the situation of lasting seepage, when avoiding energy converting pipe to wear and tear, large quantity of moisture is revealed, and causes flue blockage.
Below in conjunction with accompanying drawing, the invention will be further described.
