Description

A kind of feed pipe of pyrocrack furnace

Technical field

The pyrocrack furnace equipment technical field of biomass material is the utility model is related to, specially a kind of pyrocrack furnace is sent Expects pipe.

Background technology

In the production process of natural gas energy resource, conventional biomass material pyrolysis furnace is stirred mixed to biomass material Close, the feed pipe of the pyrocrack furnace used at present, be the straight tube of vertical direction, due to blanking excessive velocities, biomass material Easily accumulation, and then make a sweeping through the material amount excessive, cause mixed effect poor, stirring efficiency is low.

Utility model content

The purpose of this utility model is in background technology is overcome the shortcomings of, there is provided a kind of feed pipe of pyrocrack furnace, this The feed pipe of kind pyrocrack furnace overcomes the problem of biomass material accumulation, makes the uniform blanking of biomass material, controls every time Sweeping through the material amount, thus good mixing effect, stirring efficiency is high.

To achieve the above object, the utility model provides following technical scheme：A kind of feed pipe of pyrocrack furnace, including this Body, the body are hollow pipelines, and the both ends of the body are straight tubes, and the centre of the body is spirality pipe, described The bottom of spirality pipe is provided with axially extending bore of multiple diameters much smaller than body diameter, the spirality pipe along the hand of spiral Lead angle be more than 30 °.

Preferably, four quadrantal points of circumference where the axially extending bore is arranged on spirality pipe.

Preferably, the diameter of the axially extending bore is the 1/4 of body diameter.

Preferably, the lead angle of the spirality pipe is 45 °.

Compared with prior art, the beneficial effects of the utility model are：

1st, the feed pipe of the pyrocrack furnace, using spirality pipe feeding, in the bottom of spirality pipe along the hand of spiral And four quadrantal points of circumference where spirality pipe set multiple diameters to be much smaller than the axially extending bore of body diameter, are easy to give birth to Material charge disperses to fall into mixing chamber in dropping process, prevents packing phenomenon occur in feed pipe exit, controls every time Sweeping through the material amount, shorten mixing time, improve stirring efficiency.

2nd, the feed pipe of the pyrocrack furnace, according to the blending characteristics of biomass material and production requirement, spirality pipe Lead angle be more than 30 °, be easy to biomass material at the uniform velocity even drop down.

3rd, the feed pipe of the pyrocrack furnace, it is reasonable in design, there is easy to manufacture, cost is low, easy to use etc. excellent Point.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of feed pipe of pyrocrack furnace provided by the utility model, including body 1, institute It is hollow pipeline to state body 1, and the both ends of the body 1 are straight tubes 11, and the centre of the body 1 is spirality pipe 12, institute The bottom for stating spirality pipe 12 is provided with axially extending bore 13 of multiple diameters much smaller than the diameter of body 1, the spiral shell along the hand of spiral The lead angle for revolving shape pipeline 12 is more than 30 °.

Four quadrantal points of circumference where the axially extending bore 13 is arranged on spirality pipe.

The diameter of the axially extending bore 13 is the 1/4 of the diameter of body 1.

The lead angle of the spirality pipe 12 is 45 °.

Operation principle：Using the pyrocrack furnace feed pipe when, the top straight tube 11 first by biomass material by body 1 Be sent into, biomass material is advanced along spirality pipe 12 due to Action of Gravity Field, due in the bottom of spirality pipe 12 along spiral Direction is provided with axially extending bore of multiple diameters much smaller than the diameter of body 1 in four quadrantal points of the place circumference of spirality pipe 12 13, when biomass material often passes through a quadrantal points, the part that will be dropped from axially extending bore 13 is to mixing chamber, until under reaching The straight tube 11 in portion exports, and realizes biomass material and is dispersed into mixing chamber, it is therefore prevented that it is existing accumulation occur in feed pipe exit As controlling each sweeping through the material amount, shortening mixing time, good mixing effect, improve stirring efficiency.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it can still be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered Row equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., all should Within the scope of protection of the utility model.
