Description
Technical Field
The utility model relates to a carbon trade pitch flue gas dust pelletizing system technical field, concretely relates to a extinguishing device for pitch flue gas dust pelletizing system.
Background
Asphalt smoke discharged in carbon production mainly contains compounds such as asphaltene, mineral oil, resin, oxygen, sulfur, nitrogen and the like and paraffin rosin particles, and the asphalt smoke has strong adhesiveness, is easy to burn, has odor and toxicity, seriously pollutes the environment and has high treatment difficulty, thus becoming a technical problem which is urgently needed to be solved in the carbon industry. At present, carbon enterprises adopt an asphalt smoke black method to purify and treat asphalt smoke, as shown in fig. 1, the asphalt smoke is sucked into a dust collector A from a pipeline under the action of negative pressure suction of an induced draft fan, carbon powder is added into the pipeline above the dust collector, the carbon powder and the asphalt smoke are fully mixed in the dust collector, in order to prevent tar in the asphalt smoke from condensing, air is introduced by the induced draft fan, the air is heated by an electric heater, hot air enters the dust collector from the pipeline to heat the asphalt smoke, and the carbon powder and the smoke are fully mixed and then enter a bag-type dust collector B to be adsorbed and recycled.
In the existing asphalt smoke black method purification treatment method, because an electric heater adopts resistance wires to heat air, electric sparks can be generated due to short circuit caused by electrical faults, the electric sparks enter a pipeline to be combusted with asphalt smoke, system explosion is caused, and particularly, when a dust remover and the pipeline are overhauled and fire-works, the pipeline tar and a cloth bag can be ignited to cause fire and explosion.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art, and providing the fire extinguishing device of the asphalt smoke dust removing system, which has simple structure and convenient use and can quickly and effectively extinguish fire by taking steam.
The purpose of the utility model is realized through the following technical scheme:
a fire extinguishing device for an asphalt flue gas dust removal system comprises a steam pipe communicated with a dust remover or a dust collector of the asphalt flue gas dust removal system, a first stop valve and a second stop valve which are arranged on the steam pipe, wherein a steam branch pipe provided with a steam drain valve is arranged on the steam pipe between the first stop valve and the second stop valve; the other end of the steam pipe is connected with a steam boiler.
The utility model has the advantages that: the device of the utility model is additionally arranged on the dust collector and the dust collector of the asphalt flue gas dust removal system, when the second stop valve of the steam inlet is initially opened, the first stop valve, the third stop valve and the fourth stop valve are closed, and condensed water and air accumulated in the steam pipe are rapidly discharged through the opened bypass valve, so that the fault caused by air blockage is prevented; then the third stop valve is opened, the bypass valve is closed, the steam trap starts to work normally, the device enters a normal standby state, and when a fire disaster happens to the dust removal system, the steam can quickly and effectively enter a dust remover or a dust collector by opening the first stop valve, so that quick fire extinguishment is realized; when the steam trap fails and can not normally drain water, so that production is influenced, the steam trap can be compensated through the bypass valve, and even the bypass valve is temporarily used for replacing the steam trap to work; when the steam trap is overhauled by closing the third stop valve and the fourth stop valve, the bypass valve drains water emergently, so that the steam trap is convenient to overhaul. The utility model discloses simple structure easily makes, convenient to use, can be fast, effectual steam of taking when ensureing to put out a fire to reach quick fire extinguishing, also avoided the artifical danger of overhauing the operation of starting a fire simultaneously.
Drawings
FIG. 1 is a schematic structural diagram of a pitch flue gas dust removal system in the prior art.
FIG. 2 is a schematic structural view of the present invention;
figure 3 is the utility model is a schematic diagram for pitch flue gas dust pelletizing system.
Detailed Description
The invention will now be further elucidated with reference to the drawings and examples.
As shown in fig. 2 and 3, the fire extinguishing apparatus for asphalt flue gas dust removal system provided by the present invention comprises a steam pipe 1 communicated with a dust collector or dust collector of asphalt flue gas dust removal system, a first stop valve 2 and a second stop valve 3 arranged on the steam pipe, a steam branch pipe 11 provided with a steam trap 5 is arranged on the steam pipe between the first stop valve 2 and the second stop valve 3, a third stop valve 4 and a fourth stop valve 6 are respectively arranged on the steam branch pipes in front of and behind the steam trap, and a bypass valve 7 is arranged in front of the third stop valve 4 and behind the fourth stop valve 6; the other end of the steam pipe is connected with a steam boiler.
The principle and the operation process of the utility model are as follows:
install simultaneously on pitch flue gas dust pelletizing system's dust remover and dust arrester the utility model discloses a device, when the second stop valve of steam inlet was opened to the initial, close first stop valve, third stop valve and fourth stop valve, condensate water and the air that store up in the steam pipe discharge rapidly through the bypass valve of opening, later open the third stop valve, close the bypass valve, this device gets into normal standby, when dust pelletizing system takes place the conflagration, open first stop valve, steam gets into dust remover or dust arrester fast, dilute or replace combustible gas and combustion-supporting gas in dust remover or the dust arrester, reduce combustible gas and combustion-supporting gas concentration, thereby reach effective stifling and put out a fire. The utility model has simple structure, easy manufacture and convenient use, and can ensure that steam can be taken quickly and effectively when fire is extinguished, thereby achieving quick fire extinguishing; the danger of manual maintenance and firing operation can be avoided.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
