A kind of filter that is used for gas pipeline
Technical field:
The utility model relates to the ceramic tile production equipment technical field, refers in particular to a kind of filter that is used for gas pipeline.
Background technology:
Have only place, transfer gas station to be provided with a filter for installation at present in the ceramic kiln gas piping system, can not fully the tar in the coal gas be filtered fully, therefore coal gas will produce impurity in the process of burning, and ceramic kiln all is to adopt flame bare firing technology, flame and product Direct Contact Heating are so this impurity will have a strong impact on the quality of product attached to product surface.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of filter that is used for the simple in structure of gas pipeline and can effectively removes combustion gas impurity is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of filter that is used for gas pipeline, it includes air inlet pipe, filtering tank, coke discharging tube, screen pack, escape pipe, wherein, air inlet pipe is connected in filtering tank one side, the filter opposite side is provided with escape pipe, is provided with screen pack in the filtering tank of escape pipe below, and coke discharging tube and filtering tank lower end link.
Described filtering tank lower end is a turbination, and obconic tip and coke discharging tube link.
Described screen pack is divided into purifying area and filtering area with filtering tank, and escape pipe is positioned at purifying area.
The utility model is after having adopted such scheme, also not filtering the filter of impurity such as tar completely by this programme in the coal gas through transfer gas station filter filters once more, will increase substantially the degree of purity of combustion gas, significantly reduce the impurity of generation of the process of burning, improve the quality of products.
Description of drawings:
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is a filter enlarged diagram of the present utility model.
Reference numeral: 1-air inlet pipe, 2-filtering tank, 3-coke discharging tube, 4-screen pack, 5-escape pipe.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing 1 and accompanying drawing 2, preferred embodiment of the present utility model is: the described filter that is used for gas pipeline of present embodiment includes air inlet pipe 1, filtering tank 2, coke discharging tube 3, screen pack 4, escape pipe 5, wherein, air inlet pipe 1 is connected in filtering tank 2 one sides, the filter opposite side is provided with escape pipe 5, be provided with screen pack 4 in the filtering tank 2 of escape pipe 5 belows, screen pack 4 is divided into purifying area and filtering area with filtering tank 2, and escape pipe 5 is positioned at purifying area.Combustion gas enters the filtering area of filtering tank 2 from air inlet pipe 1, by screen pack 4 filtrations such as impurity in the combustion gas and tar is got off again, has become pure coal gas to enter purifying area, enters into gas piping from escape pipe 5 at last, is fed in the postorder burner and burns.Filtering tank 2 lower ends are turbination, and obconic tip and coke discharging tube 3 link.Impurity after the filtration is discharged by coke discharging tube 3.Adopt simple in structure behind this programme and increased substantially the degree of purity of combustion gas, significantly reduce the impurity of generation of the process of burning, improve the quality of products.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
