Description

Filter cloth protection of dust collector.

The present invention relates to a dry dust collector which collects coke dust. More specifically, the coke dust introduced into the hopper does not directly impact the filter cloth inside the hopper, thereby minimizing the impact and wear of the filter cloth, thereby greatly improving durability. It relates to a filter cloth protection device of the dust collector which is improved to make.

In general, the dust collector 100 collecting the coke dust is connected to the coke charging device 110 and the coke cutting device 120 is downstream of the collecting hopper 130 receiving the coke dust, as shown in FIG. A hopper 150 having a plurality of dust collecting chambers 152 is mounted through the inlet duct 140, and an exhaust duct 160 is mounted upstream of the dust collecting chamber 152 to remove coke dust. It will be discharged to the stack 180 through). Then, the lower side of each dust chamber 152 is equipped with a feeder device 190 for collecting and discharging coke dust.

As shown in FIG. 2, the dust collector 100 is equipped with a filter cloth 200 for filtering and removing coke dust from air inside the hopper 150 constituting the dust collecting chamber 152. The lower side of the (200) is provided with a guide baffle 210 formed by bending the tip of the inlet duct 140 to the lower side, the feeder device 190 through the rotary valve 188 to the lower side of the hopper 150 To be mounted. In addition, the upper side of the hopper 150 has a structure in which the impact device 220 and the discharge duct 160 for impacting the filter cloth 200 is mounted.

However, in the conventional dust collector 100 as described above, when the air containing coke dust is introduced into the dust collection chamber 152 of the hopper 150 by the inlet duct 140, the guide baffle 210 is raised. Once the sprayed to the lower side to the upper side by hitting the filter cloth 200 is to coke dust is filtered. In this process, the coke dust, which is somewhat large, directly hits the filter cloth 200 and impacts it, thereby partially wearing out part of the filter cloth 200 and thus reducing dust collection efficiency of the dust collector 100. And, the frequent maintenance of the filter cloth 200 is to increase the excessive maintenance cost.

In addition, since coke particles are concentrated on only one side, the overall use of the filter cloth 200 cannot be achieved, and there are various problems such as deterioration of dust collection performance.

The present invention is to solve the conventional problems as described above, the purpose is that the coke dust introduced into the hopper does not directly impact the filter cloth inside the hopper, thereby minimizing the impact and wear of the filter cloth to increase the durability The present invention seeks to provide an improved filter cloth protector for a dust collector to improve dust collection efficiency by dispersing coke dust and filtering the filter cloth.

In order to achieve the above object, the present invention, in the dry dust collector for separating and removing the coke dust from the air, coke dust is fixed to the lower side of the filter cloth of the dust collection chamber is overlapped and fixed across the hopper in the transverse direction By uniformly dispersing air in the transverse direction of the hopper, and by providing a filter cloth protector of the dust collector, characterized in that configured to prevent the coke dust directly hit the filter cloth.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

The filter cloth protection device 1 of the dust collector according to the present invention is equipped with a filter cloth 200 for filtering and removing coke dust from the air on the inside, the lower side of the filter cloth 200 of the inlet duct 140 The tip is provided with a guide baffle 210 formed by bending to the lower side, and the feeder device 190 is mounted to the lower side through the rotary valve 188, while the filter cloth 200 is provided on the upper side of the filter cloth 200. It is mounted inside the hopper 150 to which the impact device 220 and the discharge duct 160 that impact the shock are mounted.

As shown in FIG. 3, the protection device 1 includes a plurality of collision bars 10 transversely crossing the hopper 150 at the lower side of the filter cloth 200 of the dust collecting chamber 152. The bar is fixed, the collision bar 10 is arranged side by side at a predetermined interval with a cross-section of the ,, the collision bar 10 is to be laminated in the upper and lower layers, both sides are fixed to the support 20, respectively.

In addition, the upper and lower layers are alternately arranged with each other, that is, in FIG. 3, the collision bar 10 of the lower layer is disposed in the interspace S of the collision bar 10 of the upper side, respectively, and each collision of the upper side is performed. The bar 10 is disposed in the interspace S of the collision bar 10 on the lower side, so that the bar 10 has a lamination structure distributed over the whole in the lateral direction of the hopper 150 as a whole.

Filter cloth protection device 1 of the present invention is configured as described above is a collision bar 10 formed in a stack uniformly distributes air containing coke dust in the lateral direction of the hopper 150, coke dust directly filter cloth It is prevented to hit 200. As shown in FIG. 4, coke dust and air are introduced into the dust collection chamber 152 through the guide baffle 1 provided at the tip of the inlet duct 140, and the coke dust is directed downward. It is raised by turning in the direction toward the upper side. In this case, the coke dust is flow resistance is generated by a plurality of impact bars 10 of the cross-section arranged in a stack, evenly distributed to the circumferential surface side of the hopper 150, between the collision bar 10 of the upper and lower layers The speed of the coke dust is reduced by hitting the collision bar 10 before reaching the filter cloth 200, while changing direction to the space of the air, and is raised as the pressure sucked to the upper side by the blower 170 to the gentle speed. As a result, the filter cloth 200 is reached. Therefore, damage to the filter cloth 200 is prevented by minimizing the impact pressure and abrasion phenomenon applied to the filter cloth 200 by coke dust.

In order to illustrate the effect of the present invention in more detail, Table 1 shows the degree of breakage of the filter cloth 200 according to the prior art and the present invention, respectively.

TABLE 1

As can be seen in Table 1, it can be seen that the number of replacement of the filter cloth 200 according to the present invention during the substantially same period of use is 20, which is significantly reduced compared to the conventional 103.

As described above, according to the present invention, the coke dust introduced into the hopper 150 does not directly collide with the filter cloth 200 inside the hopper 150, thereby minimizing the impact and wear of the filter cloth 200. The durability is greatly improved, and the filter cloth 200 is filtered by dispersing coke dust so that an improved effect is obtained to improve dust collection efficiency.
