Description
Technical field
The utility model relates to a kind of screen pipe on emission-control equipment.
Background technology
In existing waste gas purification process, DeGrain, use cost is very high, be unfavorable for long-run development, one of them is very bad to the mixed effect between waste gas and filtered fluid, and direct Producing reason merges not between waste gas and filtered fluid, and waste gas also exists residual gas in uphill process, cause exhaust treatment efficiency low, have much room for improvement.
Utility model content
The purpose of this utility model is to provide a kind of screen pipe, greatly improves the dispersing uniformity of waste gas, improves the degree of mixing between waste gas and filtered fluid.
To achieve these goals, the technical solution of the utility model is as follows:
Screen pipe, it is characterized in that: comprise tipping tube, and form tapered helix tube at the end of tipping tube, described tipping tube inside forms annular boss, the first gap is formed between described annular boss and described tipping tube tube wall, the width in described first gap is at 5-10mm, and the length of described annular boss is 3/4 of described tipping tube length, and described helix tube inside forms the first annular table, the second annular table, the 3rd annular table and the 4th annular table that arrange at equal intervals; Formed closely between described first annular table outer wall and described helix tube inwall, middle part forms 3-4 bar through hole, and the diameter of described through hole is 3-5mm; Form many sulculuses between described second annular table and described helix tube inwall, the diameter of described sulculus is 2-3mm; Formed closely between described 3rd annular table and described helix tube inwall, middle part forms 3-4 bar groove not of uniform size, the section of oblique setting is formed in described groove, the width of described groove is for forming many articles of passages between the 4th annular table and described helix tube inwall described in 1-2mm, the diameter of described passage is 0.5-1mm, form portalling of communicating between described passage with described helix tube tube wall, the other end of described 4th annular table is blind end.
Do further preferably the utility model, described annular boss is arranged on the middle part of described tipping tube.
Do further preferably the utility model, the end, one end of described annular boss is mutually neat with the end of the described tipping tube port of export.
The utility model compared with prior art, has following beneficial effect:
1, the utility model comprises tipping tube, and form tapered helix tube at the end of tipping tube, described tipping tube inside forms annular boss, the first gap is formed between described annular boss and described tipping tube tube wall, the width in described first gap is at 5-10mm, and the length of described annular boss is 3/4 of described tipping tube length; Such vibrational power flow, carries out compression extruding conveying by the gas of being come in by gasing pump conveying, during by the first gap, gas is extruded and forms a lot of minute bubbles, waste gas is progressively separated, is beneficial to follow-up bubble and is separated further.
2, the inside of helix tube described in the utility model forms the first annular table, the second annular table, the 3rd annular table and the 4th annular table that arrange at equal intervals; Formed closely between described first annular table outer wall and described helix tube inwall, middle part forms 3-4 bar through hole, and the diameter of described through hole is 3-5mm; The diameter of this through hole is less than the first gap, be separated by the waste gas behind the first gap further like this, large space is entered from little space from the waste gas of the first gap process, pressure discharges suddenly, become rapid, but become again less space when being through first ring shape platform, be separated further from less bubble.
3, the second annular table described in the utility model and form many sulculuses between described helix tube inwall, the diameter of described sulculus is 2-3mm; The diameter of this sulculus is less than this through hole, be separated by the waste gas after this through hole further like this, large space is entered from little space from the waste gas of this through hole process, pressure discharges suddenly, become rapid, but become again less space when being through the second annular table, be separated further from less bubble.
4, formed closely between described 3rd annular table and described helix tube inwall, middle part forms 3-4 bar groove not of uniform size, and in described groove, form the section of oblique setting, the width of described groove is 1-2mm; Carry out separation by section in the utility model and smash bubble, formed than bubble less before.
5, many articles of passages are formed between described 4th annular table and described helix tube inwall, the diameter of described passage is 0.5-1mm, portalling of communicating is formed between described passage with described helix tube tube wall, the other end of described 4th annular table is blind end, the diameter that bore dia is greater than passage is gone out in the utility model, suddenly large space is become like this from the bubble of passage process, form larger impact dispersion force, good fusion is formed like this with outside filtered fluid, improve the uniformly dispersed of waste gas, degree of mixing improves greatly.
As from the foregoing, the utility model improves the dispersing uniformity of waste gas greatly, improves the degree of mixing between waste gas and filtered fluid.
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
