Description
Technical field
The utility model relates to micro-wave energy and uses the flue gas pump drainage mouth in field, particularly a kind of microwave-heating biomass equipment in the industrialization of the industries such as metallurgy, chemical industry, biomass pyrolytic.
Technical background
While using micro-wave energy pyrolysis biomass, can supervene the flue gas that is rich in a large number vaporization tar.And while carrying out industrialization continuity operation, just must be to being rich in that the flue gas of vaporization tar carries out in time and pump drainage effectively, otherwise cannot produce.The flue gas pump drainage mouth of microwave-heating biomass equipment in prior art, mostly adopt diameter to be less than the Process plate of 5mm, or the rectangular structure design of elongated tubulation, although two kinds of structures can effectively intercept microwave in microwave heating cavity, but when the flue gas that is rich in a large number vaporization tar passes through, because of temperature and flow velocity decline, tar liquefaction and at the Adhesion enhancement of hole wall and tube wall, very easily by aperture with ∕ or elongated tubulation are rapid, and stop up completely gradually, the flue gas that causes being rich in a large number vaporization tar can not be timely, can not pump out even completely, pressure in microwave heating cavity increases suddenly, and then cause equipment failure.Even if shut down maintenance, also can only move very short time after reproducing.Due to the problem thoroughly not solving, identical problem still takes place frequently, and production efficiency is extremely low.
Summary of the invention
The purpose of this utility model is to provide a kind of flue gas pump drainage mouth of microwave-heating biomass equipment.Its reverse microwave transmission characteristic of utilizing, dexterously unique inhibition waveguide segment and skew T element structure are combined in the design of heavy caliber, major path flue gas pump drainage mouth of microwave-heating biomass equipment, effectively overcome prior art above shortcomings part, its shape, structure or it is in conjunction with having proposed a kind of practical new technical scheme that is suitable for.
The utility model is achieved through the following technical solutions: a kind of flue gas pump drainage mouth of microwave-heating biomass equipment, formed by bottom straight way, top bend and flange, the outstanding difference of itself and prior art is: bottom straight way is the inhibition waveguide segment of a box-like body, the bottom that suppresses waveguide segment is communicated with microwave heating cavity, the opening part mounting flange of top one side, the open communication top bend of top opposite side, top bend is a up-small and down-big skew T member, the bottom mounting flange of skew T member, top connects outside flue gas pump drainage pipeline.
The minor face that suppresses waveguide segment is 50～300 ㎜, and long limit is 300～1000 ㎜, is highly 500～3000 ㎜, and between the wall of the hypotenuse of skew T member and inhibition waveguide segment, angle is 15～75 °.
The structure design of the utility model uniqueness; in industrialization, the consecutive production of use micro-wave energy pyrolysis biomass are put into practice; both by microwave safe, reliable shielding in microwave heating furnace chamber; effectively solve again tar and stopped up aperture and elongated tubulation; the difficult problem that dirt settling cannot be cleared up; not needing to shut down can be in time, easily by the tar Collection and use of deposition, production efficiency significantly improves.
Below in conjunction with drawings and Examples, the utility model is set forth.
Brief description of the drawings

Embodiment
Embodiment is intended to describe in further detail and explain the utility model, instead of limits by any way the utility model.Any simple modifications and replacement that those of ordinary skill in the art do the utility model, within all should falling into protection domain of the present utility model.
A kind of flue gas pump drainage mouth of microwave-heating biomass equipment, formed by bottom straight way, top bend and flange, the outstanding difference of itself and prior art is: bottom straight way is the inhibition waveguide segment 2 of a box-like body, the bottom that suppresses waveguide segment 2 is communicated with microwave heating cavity 1, the opening part mounting flange 3 of top one side, the open communication top bend of top opposite side, top bend is a up-small and down-big skew T member 4, the bottom mounting flange 5 of skew T member 4, top connects outside flue gas pump drainage pipeline.
The minor face that suppresses waveguide segment 2 is 50～300 ㎜, and long limit is 300～1000 ㎜, is highly 500～3000 ㎜, and between the wall of the hypotenuse of skew T member 4 and inhibition waveguide segment 2, angle is 15～75 °.
Because normal, the low-loss transmission of different frequency microwave all need different transmission paths, rationally use microwave knowledge, pass through accurate calculation, adopt reasonably high long ratio, reverse engineer the inhibition waveguide segment 2 that produces are as the bottom straight way of flue gas pump drainage mouth, be communicated with microwave heating cavity 1, both can suppress microwave, prevent that microwave from leaking, increase again flue gas pump drainage mouth size, prevent from stopping up, being convenient to cleaning, improve the pump drainage efficiency of flue gas; Suppress the opening part mounting flange 3 of waveguide segment 2 top one sides, for the capping of observation easy for installation and maintenance; Suppress the open communication top bend of waveguide segment 2 top opposite sides, top bend is a up-small and down-big skew T member 4, and skew T member 4 forms a downward inclination angle with suppressing waveguide segment 2, and the flue gas that is rich in a large number vaporization tar is during by up-small and down-big passage, because channel cross-sectional area becomes large, temperature and flow velocity decline, and tar liquefaction, is attached on the hypotenuse wall of skew T member 4, and downward curtain coating, until bottom, the bottom mounting flange 5 of skew T member 4, for installing the gate valve of discharge tar; The top of skew T member 4 connects outside flue gas pump drainage pipeline.
Carry out in industrialization, successional production practice at the HIGH-POWERED MICROWAVES pyrolysis biomass equipment that adopts microwave input general power 200～800KW, the minor face of the inhibition waveguide segment 2 of flue gas pump drainage mouth is 50～300 ㎜, long limit is 300～1000 ㎜, be highly 500～3000 ㎜, between the wall of the hypotenuse of skew T member 4 and inhibition waveguide segment 2, angle is 15～75 °.Can completely safe and cleanly to bamboo wood, timber and straw kind biomass, and the material such as coal, tar and organic waste carries out pyrolysis processing.
The utility model is also applicable to microwave metallurgical chemical industry equipment completely.
