Abstract

The utility model discloses an aluminum pig smelting furnace with a dustless exhaust system. The aluminium pig smelting furnace with the dustless exhaust system comprises a plurality of smelting furnace sets (1). A flue (2) for exhausting smoke is connected externally on a furnace body of each smelting furnace. An outlet of the flue (2) is connected with a dust collection system (8). The aluminium pig smelting furnace with the dustless exhaust system can effectively reduce flue gas exhausted into the air so as to effectively prevent adverse effect produced by aluminium pig smelting on the environment. The dustless exhaust system uses a bag to absorb dust and has high dedust efficiency and stable capacity. Treated air quantity, dust content of gas, temperature and other working conditions can exert little influence on dedusting of a bag filter. The bag filter is dry purification equipment needless of water so that a problem of sewage or mud treatment is solved and collected dust is easy to recycle. The aluminium pig smelting furnace with the dustless exhaust system has the advantages of being simple in structure, stable in operation, low in initial investment and convenient to maintain.

Description

A kind of aluminium ingot smelting furnace with dustless exhaust system
Technical field
The utility model relates to smelting furnace, particularly the exhaust system of aluminium ingot smelting furnace.
Background technology
The aluminium ingot smelting furnace is the visual plant that aluminium ingot is produced, and raw material is removed the impurity formation aluminium ingot of casting again after high temperature melting is liquid in the aluminium ingot smelting furnace.Can produce a large amount of smoke contamination air during the interior melting of aluminium ingot aluminium ingot smelting furnace, present aluminium ingot smelting furnace has disposed the aluminium dust recovery system mostly, can not play effective recovery effect but such recovery system can only reclaim the larger dust of particle to the less dust of particle, cause the pollution to environment.
The utility model content
In order to address the above problem, the utility model provides a kind of aluminium ingot smelting furnace with dustless exhaust system can effectively reclaim the less flue dust of particle, protection of the environment.
The technical solution adopted in the utility model: a kind of aluminium ingot smelting furnace with dustless exhaust system, it comprises some groups of smelting furnaces, the flue of external connection row smoke gas is communicated with the aluminium dust recovery system on the body of heater of smelting furnace on the flue bypass pipe, and the outlet of described flue is connected with dust collecting system.
Above-mentioned dust collecting system comprises snail dust separator, some groups of cloth bag dust catchers, centrifugal fan and chimneys of successively pipe connection.
Above-mentioned cloth bag dust catcher is two groups.
The beneficial effects of the utility model are: dust collecting system can effectively reduce and is discharged into the adverse effect that airborne flue dust prevents that effectively the aluminium ingot melting from producing environment.Dust collecting system adopts the cloth bag dust suction, and efficiency of dust collection is very high, stable performance.Process the variation of the conditions of work such as air quantity, gas dust content, temperature, little on the dust removing effects impact of sack cleaner.The cloth-bag type dust catcher is a kind of dry cleaning equipment, does not need water, so do not have sewage disposal or mud conditioning problem, the dust of collection is recycled easily.Relatively simple for structure, running and comparing is stable, and initial outlay is less, easy maintenance.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Present embodiment as shown in Figure 1, it comprises some groups of smelting furnaces 1, the flue 2 of external connection row smoke gas on the body of heater of smelting furnace 1 is communicated with aluminium dust recovery system 7 on flue 2 bypass pipes, the outlet of flue 2 is connected with dust collecting system.Dust collecting system has various ways, and optimal way is that cloth-bag type gathers dust.Dust collecting system comprises snail dust separator 3, some groups of cloth bag dust catchers 4, centrifugal fan 5 and chimneys 6 of successively pipe connection.Cloth bag dust catcher 4 is two groups better effect.
The dust of larger particles is recovered system 7 and recycles the less dust flue gas of particles and then continue to pass in the dust collecting system by flue in the flue dust.In dust collecting system, flue gas at first enters in the snail dust separator 3, and dusty gas imports between the shell and blast pipe of deduster, forms the downward outer eddy flow of rotation.The dust that is suspended in outer eddy flow is shifted to wall under the effect of centrifugal force, and is discharged by the dirt hole with the outward turning deduster bottom that circulates.Then enter cloth bag dust catcher 4 through the gas after dust separator 3 separation and carry out further purified treatment.Effect downstream at deep bead after dusty gas is entered by the ash bucket top air inlet on the dust catcher in cloth bag dust catcher 4 upwards flows, flow velocity reduces, thereby part bulky grain dirt powder is because the further filtering smoke of ash bucket that the inertia force effect is separated and falls into filter bag.Thereby then finish the step of gathering dust by centrifugal fan 5 guiding from chimney 6 discharges through the gas after filtering.
