Description
Technical field
The present invention relates to a kind of dust removal filter with air inlet distributed architecture.
Background technology
Existing dust removal filter, comprise filter cylinder, the bottom of this cylindrical shell is provided with taper expansion chamber, in cylindrical shell, arrange many filter cores are installed by orifice plate, in cylindrical shell, be positioned at orifice plate top and form air-purifying chamber, between orifice plate bottom and taper expansion chamber, form former air chamber, cylindrical shell is provided with the air inlet being connected with described former air chamber and the exhaust outlet being connected with described air-purifying chamber.When work, gas to be filtered enters former air chamber from air inlet, and the clean gas after filter element filtering enters air-purifying chamber, finally discharges from exhaust outlet; The ash fall filtering down is to the bottom of taper expansion chamber, while needs from bottom ash discharging hole removal.Because the air inlet of this dust removal filter is set directly on the sidewall of cylindrical shell, the distribution of gas to be filtered that enters former air chamber from air inlet is inhomogeneous, makes the service condition of different filter cores have larger difference, finally affects filter efficiency.
Utility model content
The application's technical problem to be solved is to provide a kind of dust removal filter that can make the distribution of gas to be filtered of former air chamber have more uniformly air inlet distributed architecture.
The application has the dust removal filter of air inlet distributed architecture, comprise filter cylinder, the bottom of this cylindrical shell is provided with taper expansion chamber, in cylindrical shell, arrange many filter cores are installed by orifice plate, in cylindrical shell, be positioned at orifice plate top and form air-purifying chamber, between orifice plate bottom and taper expansion chamber, form former air chamber, cylindrical shell is provided with the air inlet being connected with described former air chamber and the exhaust outlet being connected with described air-purifying chamber, the outside cover of cylindrical shell has the annular intake pipe that is connected with admission line, on cylindrical shell, be circumferentially interval with multiple air inlets, each air inlet is connected with described annular intake pipe by an inlet manifold respectively.
Because the outside cover of cylindrical shell has the annular intake pipe that is connected with admission line, on cylindrical shell, be circumferentially interval with multiple air inlets, each air inlet is connected with described annular intake pipe by an inlet manifold respectively, therefore, the application's dust removal filter has added the admission of cylindrical shell, by these, the multiple admissions along cylindrical shell circumferential arrangement enter respectively former air chamber to gas to be filtered, thereby have greatly improved the uniformity of distribution of gas to be filtered in former air chamber, make the service condition of every filter core consistent.
To partly provide in the following description the utility model is described further, the utility model is additional aspect and advantage below in conjunction with the drawings and specific embodiments, part will become obviously from the following description, or recognize by practice of the present utility model.
