Abstract
The utility model discloses a feeder for co-gasification of coal and biomass. The feeder comprises a charging hopper and a feeding pipe, the feeding pipe is connected to the charging hopper and a gasification reactor, a spiral shaft penetrates through the feeding pipe, one end of the spiral shaft is connected with a motor, a spiral blade and a mixing blade are arranged on the spiral shaft, the mixing blade is arranged on section body, corresponding to the lower part of the charging hopper, of the spiral shaft, the feeding pipe comprises a first feeding pipe and a second feeding pipe, an intermediate stock bin is connected between the first feeding pipe and second feeding pipe and a loose air duct is arranged in the intermediate stock bin. According to the feeder, since the mixing blade is additionally arranged on the spiral shaft, the mixing blade has the effect of preventing biomass and coal from layering due to the different densities and the problem of feeding difficulty. In addition, the loose air duct arranged in the intermediate stock bin plays a role in preventing the stock from clamping and further mixing and thus the uniformity of the feeding is ensured.
Description
Technical field
The utility model relates to a kind of feeder of solid carbon organism vapourizing furnace, particularly a kind of coal and the biomass feeder of vapourizing furnace altogether.
Background technology
Biomass pyrogenation gasification is a kind of efficient Energy utilization patterns, can produce fuel gas or chemosynthesis gas.China's biomass clean efficient technique of rainwater utilization falls behind, and causes biomass resource serious waste.Because biomass energy metric density is low, and gasification, due to the more tar of the lower generation of temperature, has not only reduced the utilising efficiency of biomass but also the stability of gasification has been impacted separately.In addition, the supply of biomass is subject to the impact in season, and while gasifying separately, scale is restricted.Biomass and coal gasify altogether and can improve gasification temperature, not only can improve the gasification efficiency of biomass, reduce the generation of tar, and can solve the seasonal problem that biomass are supplied with, for the efficient utilization of biomass provides a new technological approaches.Because biomass density and coal density differ larger, to feeding belt, come difficultly, so the solid mixture charging problem of biomass and coal is the difficult point of equipment development always.
Utility model content
The purpose of this utility model is to provide a kind of feeder gasifying altogether for coal and biomass.
The technical solution that the utility model adopts is:
A kind of feeder gasifying altogether for coal and biomass, comprise loading hopper and feed-pipe, feed-pipe connects loading hopper and gasifying reactor, in feed-pipe, pass screw shaft, one end of screw shaft is connected with motor, on screw shaft, be provided with screw-blade and hybrid blade, described hybrid blade is arranged on the segment body of the corresponding loading hopper of screw shaft bottom.
Preferably, described feed-pipe comprises the first feed-pipe and the second feed-pipe, the top of the first feed-pipe connects loading hopper, the bottom of the second feed-pipe connects gasifying reactor, between the top of the bottom of the first feed-pipe and the second feed-pipe, be connected intermediate bunker, in intermediate bunker, be provided with loosening airduct, on loosening airduct, be arranged at intervals with air outlet, or on the sidewall of intermediate bunker, connect several loosening airducts.
Preferably, described intermediate bunker bottom is set to taper, on the segment body of the corresponding intermediate bunker of screw shaft bottom, is also provided with hybrid blade.
Useful technique effect of the present utility model is:
(1) on screw shaft, set up hybrid blade, hybrid blade can play the biomass and the coal layering that cause because of density difference so that the problem of difficult feed of preventing.
(2) the loosening wind energy in intermediate bunker plays and prevents " frame material " and further mixing effect, guarantees the homogeneity of charging.
