Abstract
The invention discloses a gas filter which comprises a shell welded by a steel plate and a water seal tank, wherein, a cylindrical filter element made of groundwood paper is arranged in the shell, a gas inlet opening and a pure-gas outlet opening are respectively arranged at both sides of the shell and in the same horizontal line, a pure-gas chamber cover is arranged at the upper part of the shell and is communicated with the pure-gas outlet opening, a rotary flange cover is arranged at the lower end of the shell, an oil-proof rubber cushion is arranged between the flange cover and the bottom surface at the lower end of the shell, a blowdown pipe communicated with the water seal tank is arranged on the flange cover, and an overflow pipe is arranged on the water seal tank. The invention has the advantages that the surface area of the filter element is large and the resistance is small; the filter element is good in water resistance, acid and alkali-resistance and oil resistance, and the filtering effect is good; the gas inlet opening and the gas outlet opening are in the same horizontal line, therefore, the pipeline layout is easy and the installation is convenient; the lower end cover is rotary, therefore, the filter element is convenient for replacing; the shell is welded by the steel plate, therefore, the shell is convenient for manufacture, and the cost is low; the invention has the automatic blowdown function; and the invention can be used by being matched with the gas pipelines for the kilns in the ceramic and the metallurgy industries.
Description
Technical field
The invention belongs to coal gas filter technical field, relate to a kind of gas filter.
Background technology
The coal gas filter of prior art adopts the stainless steel cloth filter core mostly, can not be with the effective filtering of impurity such as moisture content and coal tar, dust, and shell cast iron is made, and cost is high and do not have the automatic pollution discharge function, has the low and high problem of production cost of removal of impurity; In addition and since its be rectangle tabular, so also there is the little defective of effective filtration area.
Summary of the invention
The objective of the invention is to solve prior art and have the technical problem that removal of impurity is low, production cost is high and effective filtration area is little, provide a kind of gas filter, to overcome the deficiencies in the prior art.
To achieve these goals, gas filter of the present invention, comprise housing and water seal tank that steel plate is welded, be provided with cylindrical tube wood pulp paper material filter core in the said housing, be respectively equipped with gas entry and pure gas exit on the both sides same level line of housing, the top of housing is provided with pure gas chamber cover, pure gas chamber cover is communicated with pure gas exit, the lower end of housing is provided with rotary blind flange, be provided with oil-resistant rubber insert between the bottom surface, lower end of blind flange and housing, blind flange is provided with the blow-off pipe that is communicated with water seal tank, and water seal tank is provided with overflow pipe.
The present invention's beneficial effect compared with prior art is: it is long-pending big to cross cartridge surface, and resistance was little when working media passed through; Filter core is water-fast, acid and alkali-resistance, oil resistivity are good, good filtration effect; Gas entry and outlet same level line, pipeline is easily arranged, and is easy for installation; Bottom end cover is that flange is rotary, and more renew cartridge is convenient, easy; Material is the steel plate welding, is convenient to make, and cost is low; Has the automatic pollution discharge function.The present invention can with the pottery, the supporting use of metallurgy industry kiln gas piping.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present invention.
The specific embodiment
11 is blind flange rotating shafts among the figure, with reference to the accompanying drawings, it comprises housing 5 and the water seal tank 10 that steel plate is welded the present invention, be provided with cylindrical tube wood pulp paper material filter core 2 in the housing 5, be respectively equipped with gas entry 1 and pure gas exit 4 on the both sides same level line of housing 5, the top of housing 5 is provided with pure gas chamber cover 3, pure gas chamber cover 3 is communicated with pure gas exit 4, the lower end of housing 5 is provided with rotary blind flange 7, be provided with oil-resistant rubber insert 6 between the bottom surface, lower end of blind flange 7 and housing 5, blind flange 7 is provided with the blow-off pipe 8 that is communicated with water seal tank 10, and water seal tank 10 is provided with overflow pipe 9; Pure gas exit 4 is connected with the kiln gas piping.
Operation principle of the present invention: coal gas is in gas entry enters the gap of filter case 5 and cylindrical wood pulp paper material filter core 2, enter again in the cylinder of filter core, impurity is left on the filter core outer surface, pure coal gas makes progress from the cylinder of filter core, enter pure gas exit 4 through pure gas chamber cover 3, enter the kiln gas piping again; Stayed peripheral impurity by filter core, flow into automatically in the water seal tank of bottom through blow-off pipe, discharge automatically through overflow pipe, water seal depth is determined according to gas pressure.
This invention cleaner, what filter core adopted is the high-quality wood pulp paper, acid and alkali-resistance, water-fast, oil resistant, moisture content, coal tar and small impurity such as dust in the energy filtering coal gas are watched from the color of coal gas, and color shows the tobacco shape when entering cleaner, after cleaner filters, be colourless gas.
