Abstract
The utility model discloses a novel ash removal blowing air diffuser which comprises a diffusion pipe (1) and a hollow pipe (2), wherein the diffusion pipe (1) is conical; a nozzle (3) is arranged at the small caliber part of the top end of the diffusion pipe; four holes (4) are formed in the pipe wall; the hollow pipe (2) is connected with the diffusion pipe (1); the nozzle (3) of the diffusion pipe (1) is upwards arranged below the hollow pipe (2). An initial position blown by the novel ash removal blowing air diffuser is adjusted, so that ash on the whole filter bag or filter cartridge can be removed, the ash removal energy is uniform, and the ash removal capacity is high.
Description
Technical field:
The utility model relates to a kind of technical field of equipment of jetting deashing.
Background technology:
Sack cleaner and filter cartridge dust remover are one of most important equipment for deashing dedusting on the market, and these two kinds of equipment purge modes have two kinds at present: hollow steel pipe jetting deashing and hollow steel pipe add venturi combination jetting deashing.Adopt hollow steel pipe jetting deashing, from the gas of hollow pipe ejection, have very high speed, its energy mainly exists with the form of dynamic pressure, because dynamic pressure only acts on the direction that air-flow advances, inoperative to being positioned at the filter bag wall of its vertical direction, therefore its deashing ability is not good enough.Or adopting hollow steel pipe to add the venturi that venturi combination winding-up carries out in deashing ，Gai mechanism mainly installs with two kinds of forms at present: be installed under card the flush type venturi in cage and be installed on the taper venturi on card.The filtrate that the installation of flush type venturi can cause approaching filter pocket mouths cannot deashing in the height of 200～400mm, taper venturi is because the outlet diameter of Venturi tube dwindles, air-flow through filtrate accelerates the necking down mouth part at venturi through card, and this can make the overall resistance of dust pelletizing system increase and reduce deashing ability; In addition, because the existence of Venturi tube is dwindled the passage of air-flow greatly, form bottleneck, extended the time that deashing tolerance enters filter bag, make high pressure air mass become elongated and significantly weakened the impulsive force to filter bag wall, the peak value of bag internal pressure waveform is lowered, the time is elongated, make former should " height " and the pressure waveform of " suddenly " becomes " low " and the waveform of " putting down ", maximum opposite acceleration significantly reduces, thereby has weakened the deashing ability of deashing air mass in filter bag.
Utility model content:
The utility model is for the defect of prior art, provides a kind of whole piece filter bag that can make all can deashing and deashing energy even, novel deashing winding-up air diffuser that deashing ability is good.
The utility model is realized by following technical scheme.
A novel deashing winding-up air diffuser, comprises diffusing pipe and hollow pipe, and described diffusing pipe is taper, and there is a nozzle at small-bore place, its top, and its tube wall is provided with hole; Described hollow pipe is connected with diffusing pipe, and the nozzle of diffusing pipe is placed under hollow pipe upward.
As this technical scheme preferably, 4 holes are set on described diffusing pipe, and 4 holes are evenly distributed on tube wall.
As this technical scheme preferably, between diffusing pipe and hollow pipe, with connection strap, be connected.
As this technical scheme preferably, the central point of the nozzle of described diffusing pipe and the central point of hollow pipe are on same straight line.
Beneficial effect:
(1) regulate the original position that this winding-up air diffuser can regulation blowing apart from the height of filter bag, guarantee that whole piece filter bag/filter cylinder can deashing.
(2) thus whole piece filter bag/filter cylinder is in short transverse that all can obtain reverse malleation carries out deashing, deashing ability is strong and deashing Energy distribution is even.
Accompanying drawing explanation:
Fig. 1 is front view of the present utility model.
Wherein, 1-diffusing pipe, 2-hollow pipe, 3-nozzle, 4-hole, 5-brace.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of novel deashing winding-up air diffuser, is mainly comprised of diffusing pipe 1 and hollow pipe 2; Described hollow pipe 2 is formed by molten iron disposal pouring, and on tube wall, sprays the antirust paint of cyan; Described diffusing pipe 1 is welded by four identical trapezoidal iron plates, on the both sides of trapezoidal iron plate, all there is the identical half elliptic breach of a size, after having welded, form four oval holes 4 that size is identical on the tube wall of diffusing pipe 1, and on the top of diffusing pipe 1, formed a round nozzle 3; The antirust paint of cyan will be sprayed on the diffusing pipe 1 after moulding; The nozzle 3 of diffusing pipe 1 is placed in the below of hollow pipe 2 upward, between hollow pipe 2 and diffusing pipe 1, by four identical trapezoidal iron braces 5 of size, is welded together.
The hollow pipe 2 of this winding-up air diffuser is installed under jet pipe, diffusing pipe 1 is placed in the top of filter bag, during work, the hollow pipe 2 that deashing high pressure air mass enters winding-up air diffuser from jet pipe enters diffusing pipe 1 again, and at diffusing pipe 1 place, by diffusing, a part of air-flow is through nozzle 3 and the hole 4 of diffusing pipe 1, another part enters filter bag along the outer tube wall of diffusing pipe 1, the air-flow forming is like this wide and fat, has increased the impulsive force to filter bag wall, thereby has increased deashing ability; Because gas is also made the deashing energy of direction more even by diffusing; Meanwhile, can, by regulating the original position that this winding-up air diffuser can regulation blowing apart from the height of filter bag, guarantee that whole piece filter bag/filter cylinder can deashing.
