Background technology
High temperature kiln is one of equipment commonly used in the commercial production, and it often produces in the process of using contains tar, CO, CH in a large number 4, H 2Deng the high-temp waste gas of composition,, can cause very big harm to environment if these high-temp waste gas directly are discharged in the atmosphere.
In order effectively to utilize these high-temp waste gas, people generally adopt the flue gas cleaning retracting device to come the poisonous and harmful element in effective scavenging, and then the heat that reclaims is carried out second use.
Traditional high-temperature furnace gas purification recovery device reaches the effect that reduces furnace gas temperature often through mixing the mode of cold wind.Though this mode can solve the problem of furnace gas cooling, owing to contain CO, CH in the high-temperature furnace gas 4, H 2Deng composition, the accident of in mixing the process of cold wind, blasting easily, greatly dangerous; In addition, owing to also contain tar in the high-temperature furnace gas, this is in the purifying and cooling process of high-temperature furnace gas---and when furnace gas temperature was low, tar was separated out easily, in dust removal process, can cause the obstruction of cleaner; When furnace gas temperature was higher, meeting scaling loss deduster parts caused drawbacks such as maintenance cost is high, dedusting is obstructed.
The utility model content
The purpose of the utility model just provides a kind of high-temperature furnace gas purification recovery device, to solve the inconvenient problem of operation and maintenance that existing high-temperature furnace gas purification recovery device exists.
The utility model is achieved in that a kind of high-temperature furnace gas purification recovery device, comprises the purifying and dedusting device, is connected to heat pipe in the front portion of said purifying and dedusting device, is connected to tar recovery system in the bottom of said heat pipe.
Said heat pipe is to be provided with the dividing plate that said enclosure interior is divided into upper cavity and lower chamber at the housing middle part, the some vacuum heat-pipes of cross-under on said dividing plate, and said vacuum heat-pipe is provided with fin.Heat-exchanger rig adopts the vacuum heat-pipe heat exchanger; Have the collecting efficiency height, heat big, output temperature is high, carry that operation is fast, structural strength is high, long service life and characteristics such as convenient for installation and maintenance; Be arranged on the fin on the vacuum heat-pipe; Can increase the heat transfer area of vacuum heat-pipe, further improve heat exchange efficiency.
The said housing of said heat pipe is provided with the heat transferring medium input mouth of pipe and the medium output mouth of pipe that feeds said upper cavity, on the said medium output mouth of pipe, is connected to the waste heat recovery pipe; The said housing of said heat pipe is provided with the high-temperature furnace gas input mouth of pipe and the furnace gas output mouth of pipe that feeds said lower chamber, on the said furnace gas output mouth of pipe, is connected to the furnace gas recovery tube, and said furnace gas recovery tube is connected on the said purifying and dedusting device.
Said smart deduster is sack cleaner, metal dusting device or electric cleaner, can the filtrating smoke dust more than 99%, removal in the furnace gas be obtained clean furnace gas, is convenient to second use.
The described vacuum heat-pipe of the utility model not only can make the heat energy in the high-temperature furnace gas effectively pass to heat transferring medium, is convenient to second use, and can the tar in the high-temperature furnace gas be removed, and is beneficial to final dusting; In said lower chamber bottom tar recovery system is installed, can tar in the high-temperature furnace gas is collected and reclaim; Furnace gas after the cooling finally obtains the clean furnace gas of recyclable utilization again through purifying and dedusting device final dusting.The utlity model has characteristics such as rational in infrastructure, low cost of manufacture, installation and maintenance be simple, can be widely used in purification and recovery that high-temperature furnace gas particularly contains the high-temperature furnace gas of tar.
Description of drawings
Fig. 1 is the system architecture diagram of the utility model.
Among the figure: 1, vacuum heat-pipe, 2, upper cavity, 3, lower chamber, 4, the tar recover, 5, dividing plate, 6, the waste heat recovery pipe, 7, the purifying and dedusting device, 8, the furnace gas recovery tube, 9, fin, 10, housing.
The specific embodiment
As shown in Figure 1, this high-temperature furnace gas purification recovery device comprises heat pipe, purifying and dedusting device 7 and tar recovery system 4 three parts.Heat pipe is connected on the front portion of purifying and dedusting device 7, and tar recovery system 4 is connected on the bottom of heat pipe, and purifying and dedusting device 7 can be sack cleaner, metal dusting device or electric cleaner etc.
A kind of implementation of heat pipe is; At housing 10 middle parts a dividing plate 5 is set, enclosure interior is divided into upper cavity 2 and lower chamber 3, the some vacuum heat-pipes 1 of cross-under on dividing plate 5; Vacuum heat-pipe 1 is provided with fin 9; Wherein, be distributed in the formation radiating fin in the upper cavity 2, be distributed in the formation heat absorption fin in the lower chamber 3.
The housing 10 of heat pipe is provided with the heat transferring medium input mouth of pipe and the medium output mouth of pipe that feeds upper cavity 2, on the medium output mouth of pipe, is connected to waste heat recovery pipe 6.The housing 10 of heat pipe is provided with the high-temperature furnace gas input mouth of pipe and the furnace gas output mouth of pipe that feeds lower chamber 3, on the furnace gas output mouth of pipe, is connected to furnace gas recovery tube 8, and furnace gas recovery tube 8 is connected on the purifying and dedusting device 7.
Contain tar, flue dust and CO, CH 4, H 2High-temperature furnace gas Deng gas is imported the mouth of pipe through high-temperature furnace gas, gets in the lower chamber 3 of heat pipe, and heat transferring mediums such as air or water get in the upper cavity 2 of heat pipe through the heat transferring medium input mouth of pipe.
Through after the heat exchange of heat pipe, temperature is that 450~1000 ℃ high-temperature furnace gas can drop to below 150 ℃, and then gets into purifying and dedusting device 7 through furnace gas recovery tube 8, through smart dedusting, obtains reclaiming gas; And the heat that heat transferring medium comes up through 1 transmission of absorption vacuum heat-pipe, temperature raises rapidly, and the heat transferring medium after the intensification offers the user through waste heat recovery pipe 6, carries out second use.
When high-temperature furnace gas exchanges out heat in lower chamber 3 when; Contained steam condensation on the surface of vacuum heat-pipe 1 in the high-temperature furnace gas, tar in the furnace gas and flue dust adhere on the heat pipe surface of condensation water film and deposition having, and form fluffy floccule gradually; Floccule constantly deposition is block; And under the gravity effect, crash into lower chamber 3 bottoms, through flowing into communicating pipe in the tar recovery system 4, this process also is once the process of thick dedusting.After the furnace gas after the thick dedusting gets into purifying and dedusting device 7 again and carries out the smart dedusting of secondary, can remove in the furnace gas 99% flue dust, thereby but obtain the recovery gas of cleaning second use.
Above-mentioned recovery gas can use at aspects such as oven dry, heating, fire-fightings, also can be used as combustion adjuvant and returns stove, participates in burning and uses.
