Abstract
The invention discloses a flue gas treatment device of a high-temperature electric calciner, which comprises a high-temperature flue (5). The invention is characterized in that the high-temperature flue (5) is provided with a cleaning port (4); a spray gun (3) is arranged in the cleaning port (4); the spray gun (3) is connected with a nitrogen gas source (1) via a pipe (2); the high-temperature flue (5) is connected with a cooling and sediment chamber (6); a cooling grid plate (7) is arranged in the cooling and sediment chamber (6); and the cooling and sediment chamber (6) is provided with a flue gas outlet (8). The invention adopts nitrogen as the purging medium, and is capable of cleaning the dust adhered to the flue, thus greatly improving the working condition and working environment for workers; as nitrogen is adopted as the purging medium, the combustion of the combustible volatiles in the flue can be effectively avoided, the temperature of the flue gas in the flue is greatly reduced, and steel flue can be prevented from being damaged by high temperature.
Description
Technical field
The present invention relates to electric calcined anthracite or petroleum coke kiln gas treatment facility in the plain production of a kind of charcoal.
Background technology
In the electric calciner production process, rising along with calcining heat, flammable fugitive constituent, elemental sulfur and some low-melting impurity in the calcining material (anthracite or petroleum coke) can be overflowed, this moment, flue-gas temperature was usually about 800 degrees centigrade, flue gas is carried part carbonaceous powder simultaneously secretly and is directly discharged contaminated environment by the exit flue on electric calciner top.High-temperature flue gas can't be removed by general cleaner simultaneously.Because temperature is relatively low in the exit flue, low-melting impurity of part and powder can stick in the exit flue, and the exit flue circulation area is reduced, even phenomenon of blocking takes place.For this obstruction, if use conventional soot blower, use compressed air or steam to carry out the blowing-out reason as blowing medium, can in flue, cause burning, damage flue, lead to a disaster.Therefore, present treating method for this obstruction is by manually clearing up.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of high temperature electric forge furnace flue gas treating device is provided, and this device structure is simple, easy to operate, and ash disposal, dust collection effect are good, to overcome problems of the prior art.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: utilize the perforate on the smoke pipe, adopt nitrogen as blowing medium, use scavenging conduit that the position of smoke pipe and easy knot ash is purged operation; The impurity and the powder that are entrained with smoke pipe special cooling-sedimentation chamber be set, so that can and regularly be removed in this deposition.
The course of work of the present invention is as follows:
Press nitrogen (the general pressure limit 0.5～1MPa) that is fit to by the band that nitrogen source of the gas 1 provides, enter in the cleaning spray gun 3 by connecting line 2, and by the cleaning spray gun 3 the front end spout spray at a high speed, by the clean-up port of offering at flue 5 sidepieces 4, enter the dust that flue acts directly on the bonding on high-temperature flue 5 inwalls, dust is separated with the flue wall, reach the purpose of removing dust.Entering of nitrogen can be reduced flue-gas temperature rapidly simultaneously, makes the low melting point volatile matter be cooled to solid particle rapidly, and enters deposition in the cooling-sedimentation chamber 6 with flue gas.Cooling screen 7 is in order to guarantee that flue gas can be cooled to the required temperature of technology, and optimizes expansion chamber 6 air-flows and distribute, and strengthens catching dust.The flue gas of treated mistake is finally discharged by flue outlet 8.
The invention has the beneficial effects as follows: adopt nitrogen as blowing medium, can clean the dust that bonds in the flue effectively, greatly alleviate workman's working condition and work situation; Use nitrogen to purge the burning that can effectively prevent flammable fugitive constituent in the flue, reduce the temperature of flue gas in the smoke pipe, protection steel smoke pipe can Yin Gaowen and damage.
