Abstract
The utility model discloses an auxiliary mechanism of a coal-decomposed gas collecting pipe. The mechanism comprises a porous air suction pipe, one end of the air suction pipe is connected with a coal-decomposed gas collecting pipe arranged in a rotary kiln body, and the other end of the air suction pipe extends into the other side of the rotary kiln body along the axial direction of the rotary kiln body. The coal-decomposed gas collecting pipe in the rotary kiln body is connected with a section of the porous air suction pipe, thereby not only being capable of timely absorbing the coal-decomposed gas generated in the rotary kiln body, but also being capable of leading coal power which is absorbed into the air suction pipe to pass through the small holes again and return to the heat reaction in the rotary kiln body importantly, so that the pressure to the next dedusting and liquefying work can be avoided since the coal-decomposed gas can not enter a dedusting and liquefying mechanism out of the kiln through the coal-decomposed gas collecting pipe.
Description
Technical field
The utility model belongs under the dust condition collects the gas apparatus technical field, is specifically related to a kind of coal branch collecting pipe assisting agency of venting one's spleen.
Background technique
Be rich in the dust border of various particulates, the associated gas of collecting in the dust border is the technological scheme of often using in the industrial production, as collecting coal decomposition and separation gas in the rotary kiln body, generally be under airtight condition, end at the kiln body is provided with a collecting pipe, the combustion gas, the tar gas that decompose are collected, and utilization is arranged on the kiln external dedusting of dedusting liquid body, separation, pressurized liquefied.But in the concrete process of implementing; because collecting pipe only stretches out sub-fraction at an end of kiln body; absorbed speed is influenced easily on the one hand for a large amount of gas; what is more important; after a large amount of gas that is rich in various dust entered collecting pipe, the gas dust loading of collecting was too big, can bring pressure to the dedusting liquefaction in downstream; and the particle that the picture coal decomposes in the kiln still is valuable coal dust, can cause very big waste after being drawn out of.
The model utility content
The utility model provides a kind of one side can accelerate to collect the speed of gas, can effectively reduce the coal branch of collecting dust content in the gas collecting pipe assisting agency of venting one's spleen again.
A kind of coal branch collecting pipe assisting agency of venting one's spleen comprises the sucking pipe of a porous, and described sucking pipe one end and the coal branch in being arranged on the rotary kiln body collecting pipe of venting one's spleen is connected, and the other end stretches to rotary kiln body opposite side along the direction of rotary kiln body axis.
Between described sucking pipe and the rotary kiln body inwall dunnage is set.
The spiral that positive and negative alternate is provided with is set in the described sucking pipe.
The sucking pipe that connects one section porous because the coal branch of the utility model in the rotary kiln body vented one's spleen on the collecting pipe, a large amount of holes is set on the described sucking pipe, can absorb the coal branch that produces in the kiln body on the one hand timely vents one's spleen, what is more important, be sucked into the coal dust that the gas that carries a large amount of dust behind the sucking pipe discharges at the volley and can pass through these a large amount of apertures again, return in the middle of the thermal response in the kiln, be unlikely by the coal branch gas collecting tube of venting one's spleen entering in the outer dedusting liquid body of kiln and go, bring pressure for next step dedusting liquefaction work.Between described sucking pipe and the kiln body inwall dunnage is set, can guarantees stability and the reliability of sucking pipe in rotary kiln.Cooperate the positive and negative alternate spiral that is provided with in the sucking pipe, can further reduce the dust content that collecting pipe is collected gas, improved rate of energy.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model embodiment two a structural representation.
Embodiment:
Embodiment one
As shown in Figure 1: a kind of coal branch collecting pipe assisting agency of venting one's spleen, the sucking pipe 3 that comprises a porous 4, described sucking pipe 3 one ends and the coal branch in being arranged on rotary kiln body 1 collecting pipe 2 of venting one's spleen is connected, and the other end stretches to rotary kiln body 1 opposite side along the direction of rotary kiln body 1 axis.Coal branch in rotary kiln body 1 is vented one's spleen and is connected the sucking pipe of one section porous 4 on the collecting pipe 2, the coal branch that produces in the absorption kiln body that on the one hand can be a lot of is vented one's spleen, what is more important, be sucked into the coal dust that the gas that carries a large amount of dust behind the sucking pipe discharges at the volley and can pass through these a large amount of apertures again, return in the middle of the thermal response in the kiln, be unlikely by the coal branch gas collecting tube of venting one's spleen entering in the outer dedusting liquid body of kiln and go, bring pressure for next step dedusting liquefaction work.
Between described sucking pipe 3 and rotary kiln body 1 inwall dunnage 5 is set, can guarantees stability and the reliability of sucking pipe in rotary kiln.
Embodiment two
As shown in Figure 1 and Figure 2: a kind of coal branch collecting pipe assisting agency of venting one's spleen, the sucking pipe 3 that comprises a porous 4, described sucking pipe 3 one ends and the coal branch in being arranged on rotary kiln body 1 collecting pipe 2 of venting one's spleen is connected, the other end stretches to rotary kiln body 1 opposite side along the direction of rotary kiln body 1 axis, between described sucking pipe 3 and rotary kiln body 1 inwall dunnage 5 is set, the spiral 6 that positive and negative alternate is provided with is set in the described sucking pipe 3, can further reduce collecting pipe and collect the dust content of gas, improve rate of energy.
Claims (3)
