Abstract
The invention discloses an annular flow-guiding pipe filter. According to the scheme, the annular flow-guiding pipe filter comprises a shell and a pipe plate arranged in the shell, wherein a downward extending filter core is arranged on the pipe plate; an air outlet pipe is arranged on the shell above the pipe plate; an air inlet pipe is arranged on the shell; the annular flow-guiding pipe filter further comprises an annular flow-guiding pipe; the annular flow-guiding pipe is arranged on the inner wall of the shell; the annular flow-guiding pipe is communicated with the air inlet pipe; an upward flow-guiding air hole is formed in the annular flow-guiding pipe. The invention aims to provide the annular flow-guiding pipe filter for solving the problems that dust-containing air difficultly reaches the position away from an air inlet along an annular flow-guiding structure and the back flushing effect of the filter core away from the air inlet is unsatisfying caused by a fact that an opening baffle is arranged as the annular flow-guiding structure in the prior art.
Description
Technical field
The present invention relates to a kind of annular mozzle filter.
Background technology
Gas-solid filter is widely used in the industries such as the energy, chemical industry, pharmacy, environmental protection, and conventional filters in use dusty gas flows from bottom to top from filter bottom, and immobilized particles is formed filter cake by filter core interception, and purified gas is by discharging after filter core.After filtration pressure drop increases, start blowback, by high-speed pulse blow-back, surperficial filter cake is broken, come off, namely filter cake discharges in ash bucket from below.
Because filter cake is broken during blowback, the solid particulate dust that part particle diameter is less easily suspends in the gas flow, is difficult to fall into ash bucket.Especially when gas flow direction upwards, time contrary with filter cake sedimentation direction, more dust suspension can be produced, along with the prolongation of running time, dust suspension is more, increases the load of filter, easily cause plugged filter, have a strong impact on the service life of gas-solid disngaging efficiency and filter.
In prior art, air inlet pipe is stretched to filter middle portion, increase vertical gas cylinder and import to below tube sheet by gas, dusty gas flows from top to bottom after gas cylinder upper opening flows out.Gas flow after improvement and solid sedimentation direction are all downward, avoid gas and again carry immobilized particles formation suspension, again enter filter element filtering, improve the separative efficiency of gas-solid.But an obvious shortcoming of the structure of this improvement is, the tube sheet area shared by gas cylinder can not be arranged filter core.
For solving the problem, publication number is that the patent document of CN204699540U discloses a kind of filter with distribution of gas function, its technical scheme is as follows: this filter comprises housing and is arranged on the tube sheet in housing, described tube sheet is provided with the filter core to downward-extension, described housing is provided with air inlet pipe, described filter also comprises annular flow-guiding structure, this annular flow-guiding structure is arranged on the inside of described housing and is positioned at the outside of described filter core, described air inlet pipe is communicated to described annular flow-guiding structure, the dusty gas entered in described housing by this air inlet pipe is flowed downward after described annular flow-guiding structure guides.
In the technical scheme of this patent, by arranging annular flow-guiding structure, dusty gas being guided and flows downward.But due to the baffle plate that this annular flow-guiding structure is open type, dusty gas be difficult to annularly flow-guiding structure arrive away from air inlet place, make away from air inlet place filter core blowback effect undesirable.
Summary of the invention
The invention is intended to provide a kind of annular mozzle filter, to solve in prior art due to baffle plate that annular flow-guiding structure is open type, dusty gas is difficult to annularly flow-guiding structure and arrives away from air inlet place, make away from air inlet place the undesirable problem of filter core blowback effect.
Annular mozzle filter in this programme, base case is: comprise housing and be arranged on the tube sheet in housing, described tube sheet is provided with the filter core to downward-extension, housing above described tube sheet is provided with escape pipe, described housing is provided with air inlet pipe, also comprises annular mozzle, described annular mozzle is arranged in inner walls, described annular mozzle is communicated with air inlet pipe, and described annular mozzle is provided with diversion stomatal upward.
Operation principle and beneficial effect: in prior art, because annular flow-guiding structure is the baffle plate of open type, dusty gas be difficult to annularly flow-guiding structure arrive away from air inlet place, make away from air inlet place filter core dust removing effects undesirable.In this programme, owing to being provided with annular mozzle, when dusty gas enters annular mozzle by air inlet pipe, because annular mozzle only has top to offer diversion stomatal, so dusty gas can annularly arrive away from air inlet place by mozzle, and flowed out by diversion stomatal, make the air flows down in housing.In sum, the beneficial effect of this programme is by arranging annular mozzle, dusty gas annularly can be arrived away from air inlet place by mozzle, and make the air flows down in housing, thus effect when improving dedusting.
Scheme 2, as the improvement to base case, described housing bottom is provided with sewage draining exit.Advantage is, facilitates the discharge of filter cake.
Scheme 3, as the improvement to scheme 2, the top of described sewage draining exit is provided with the collecting plate be obliquely installed.Advantage is, collecting plate plays the effect of dust gathering arrester, improves the efficiency of control of dust.
Scheme 4, as the improvement to base case, described diversion stomatal is evenly arranged in the circumference of annular mozzle.Advantage is, the air of surrounding in housing can evenly be flowed downward, and improves the effect of dedusting.
Scheme 5, as the improvement to base case, be provided with valve above described filter core, described valve is communicated with escape pipe.Advantage is, valve can increase the air velocity at filter core place when blowback, improves blowback dust removing effects.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's annular mozzle filter embodiment 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: housing 10, collecting plate 20, filter core 30, annular mozzle 40, tube sheet 50, valve 60, air inlet pipe 70, escape pipe 80.
Embodiment 1
As shown in Figure 1, annular mozzle filter, scheme is: comprise housing 10 and be arranged on the tube sheet 50 in housing 10, tube sheet 50 is provided with the filter core 30 to downward-extension, the housing above tube sheet 50 is provided with escape pipe 80, housing 10 is provided with air inlet pipe 70, also comprise annular mozzle 40, annular mozzle 40 is arranged on housing 10 inwall, and annular mozzle 40 is communicated with air inlet pipe 70, and annular mozzle 40 is provided with diversion stomatal upward.
In addition, in the present embodiment, sewage draining exit is provided with bottom housing 10.Advantage is, facilitates the discharge of filter cake.The top of sewage draining exit is provided with the collecting plate 20 be obliquely installed.Advantage is, collecting plate 20 plays the effect of dust gathering arrester, improves the efficiency of control of dust.Diversion stomatal is evenly arranged in the circumference of annular mozzle 40.Advantage is, the air of surrounding in housing 10 can evenly be flowed downward, and improves the effect of dedusting.Be provided with valve 60 above filter core 30, valve 60 is communicated with escape pipe 80.Advantage is, valve 60 can increase the air velocity at filter core 30 place when blowback, improves blowback dust removing effects.
