Abstract

The utility model discloses an active carbon filter which comprises a filter cylinder and a filter assembly fixed in the filter cylinder, wherein the filter assembly is used for dividing the filter cylinder into an upper cavity and a lower cavity, and the upper cavity and the lower cavity are communicated together through an active carbon filter pipe of the filter assembly. According to the technical scheme, the filter assembly is of an independent structure and is arranged in a cylinder body through a sealing plate, the filter assembly is integrally taken out by only opening a blind plate at the upper part of the filter cylinder when being replaced, and a filter pipe can be dismantled from the filter assembly if only being replaced. Meanwhile, a porcelain ball in an original filter is saved from the top of the filter assembly, thus the filter assembly is more convenient to be taken out.

Description

A kind of active carbon filter

Technical field

The utility model belongs to environmental protection equipment technical field, especially relates to a kind of active carbon filter.

Background technology

Active carbon filter is that a kind of suction-operated that utilizes activated carbon granule is filtered, and can remove the device of the organic impurity in medium.The general mode of filling activated carbon filtration cotton in filter interior that adopts of current active carbon filter, the ball porcelain of straightening footpath 3-5mm on boiler face, this filter, although filter effect can be realized, but it is but difficult for maintenance after going wrong, ball porcelain can only be moved away, then filter core is taken apart, change and be difficult for, safeguard loaded down with trivial details.

Utility model content

Be difficult for changing in order to make up above-mentioned active carbon filter filter core, safeguard the defects such as inconvenience, the utility model proposes a kind of self-filtering filter core and hold easily changeable active carbon filter.

The technical scheme that realizes above-mentioned beneficial effect is, a kind of active carbon filter, comprise cartridge filter and be fixed on the filter assemblies in cartridge filter, cartridge filter is divided into upper and lower two chambers by described filter assemblies, passes through the activated carbon filtration pipe communication channel of filter assemblies together between upper and lower chamber.In the technical program, filter assemblies is absolute construction, is installed in cylindrical shell by sealing plate, and filter assemblies entirety in the time changing is taken out, only need open the blind plate on filter cylinder top, only need pull down screen pipe from filter assemblies if just change single screen pipe.The porcelain ball in original filter is saved at filter assemblies top simultaneously, and convenient filter assemblies takes out.

Described activated carbon filtration pipe has many.In the technical program, screen pipe is followed more, can only go to change the screen pipe that needs replacing in the time changing, and integral filter assembly is not affected.

Described screen pipe top has the air inlet being communicated with upper chamber, and bottom has the gas outlet being communicated with lower chambers, and screen pipe inside is filled with activated carbon filter media.The waste gas that in the technical program, air inlet enters flows down to lower chambers by filter medium, and gas flows downward, and increases filtration time, ensures filter quality.

On cartridge filter, be also fixed with difference gauge, the induction end of difference gauge connects together with upper and lower chamber respectively.In the technical program, utilize the suction-operated of activated carbon granule to filter medium, the impurity filtering is in the increase of filter core outer surface and filtering layer inside deposition quantity, the pressure reduction on filter assemblies bottom and top can increase gradually, this will be shown by differential manometer, in the time that pressure reduction reaches 0.1MPa, illustrate that filter core is blocked, should change activated carbon filtration pipe.

Brief description of the drawings

Fig. 1 is the structural representation of a kind of embodiment of the present utility model;

In figure, 1, cartridge filter; 2, filter assemblies; 3, upper chamber; 4, lower chambers; 5, activated carbon filtration pipe; 6, difference gauge.

Detailed description of the invention

Further illustrate utility model content below in conjunction with specific embodiment.

In conjunction with Fig. 1, a kind of embodiment of the present utility model.A kind of active carbon filter, comprises cartridge filter 1 and is fixed on the filter assemblies 2 in cartridge filter, cartridge filter is divided into upper chamber 3 and lower chambers 4 by described filter assemblies, passes through activated carbon filtration pipe 5 communication channels of filter assemblies together between upper and lower chamber.In the technical program, described activated carbon filtration pipe has many.Described screen pipe top has the air inlet being communicated with upper chamber, and bottom has the gas outlet being communicated with lower chambers, and screen pipe inside is filled with activated carbon filter media.On cartridge filter, be also fixed with difference gauge 6, the induction end of difference gauge connects together with upper and lower chamber respectively.

When in use, waste gas enters filter assemblies by upper chamber and is cleaned the utility model, and purified gas enters lower chambers and is discharged from.As Fig. 1, cartridge filter of the present utility model is removed outside the fast opening blind on top, also has sewage draining exit, drain, and access hole, a series of attached matching components such as safety valve, ensure stability and safety operation in its course of work.

The foregoing is only the embodiment of the utility model the best, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
