Abstract
The utility model discloses a fuel gas filter device which comprises a fuel gas tank connected with a tail gas tower backflow tank. The fuel gas tank is connected with a combustion furnace through a pipeline, a first control valve is arranged on the pipeline, a filter connected with the first control valve in parallel is also arranged on the pipeline, the two ends of the filter are connected with a second control valve and a third control valve respectively, the output end of the filter is connected with the combustion furnace through the third control valve, and the blow-off exit of the filter passes through a blow-off pipeline to be connected with a closed system through a fourth control valve. The fuel gas filter device is simple in structure, reasonable in design, and capable of preventing an adjusting valve and a combustor from being damaged, protecting environment and saving energy, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of combustion gas filter.
Background technology
At present, in styrene plant, the fuel of combustion furnace internal combustion comes from the tail gas tower return tank, carry so a large amount of benzene and rubber powder in combustion gas, the accidents such as this control valve to combustion furnace and burner have very large harm, easily cause direct-operated regulator malfunctioning, and blocking pipeline, stove are flame-out, have a strong impact on normal operation, be not easy to safeguard.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, provides a kind of simple in structure, reasonable in design, can prevent from control valve and burner are caused to damage environmental protection and energy saving, the combustion gas filter that can increase the service life.
Its technical scheme is: the combustion gas filter, comprise and the tail gas tower tank connected fuel gas tank that refluxes, described fuel gas tank is connected with combustion furnace by pipeline, described pipeline is provided with the first control valve, also be provided with the filter in parallel with the first control valve on described pipeline, the two ends of described filter are connected with respectively the second control valve and the 3rd control valve, the output of described filter is connected with combustion furnace by the 3rd control valve, and the sewage draining exit of described filter is connected with closed system through blow-off line by the 4th control valve.
Described filter is at least one.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, can prevent from control valve and burner are caused to damage, and environmental protection and energy saving, can increase the service life.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, the combustion gas filter, comprise and the tail gas tower tank connected fuel gas tank 1 that refluxes, described fuel gas tank 1 is connected with combustion furnace by pipeline 2, described pipeline 2 is provided with the first control valve 3, also be provided with the filter 4 in parallel with the first control valve 3 on described pipeline 2, the two ends of described filter 4 are connected with respectively the second control valve 5 and the 3rd control valve 6, the output of described filter 4 is connected with combustion furnace by the 3rd control valve 6, and the sewage draining exit of described filter 4 is connected with closed system through blow-off line 8 by the 4th control valve 7.
Described filter 4 is at least one.Filter 4 can be set to a plurality of, in parallel with the first control valve 3 respectively, can increase work efficiency.
During work, carry a large amount of benzene and rubber powder in combustion gas due to the tail gas tower return tank, close like this first control valve 3, open the second control valve 5 and the 3rd control valve 6, make combustion gas enter again the combustion furnace internal combustion after filter 4 filters, combustion gas free from admixture so after filtering, the accidents such as pipeline, stove be flame-out are difficult for resulting in blockage, and can prevent that control valve is malfunctioning, when needs reclaim the impurity filtered, open the 4th control valve 7 and the liquid phase impurity of recovery can be disposed to closed system, so not only solve the purpose that technological problems has also reached environmental protection simultaneously.
The utility model is simple in structure, reasonable in design, can prevent from control valve and burner are caused to damage that environmental protection and energy saving can increase the service life.
Claims (2)
1. combustion gas filter, comprise and the tail gas tower tank connected fuel gas tank that refluxes, described fuel gas tank is connected with combustion furnace by pipeline, it is characterized in that: described pipeline is provided with the first control valve, also be provided with the filter in parallel with the first control valve on described pipeline, the two ends of described filter are connected with respectively the second control valve and the 3rd control valve, the output of described filter is connected with combustion furnace by the 3rd control valve, and the sewage draining exit of described filter is connected with closed system through blow-off line by the 4th control valve.
