Embodiment
The invention discloses a kind of biomass class solid waste and the useless feeding system of danger, for the biomass class recycling of pyrolytic gasification technique, the requirement of follow-up gasification, and combustion can be met.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-Fig. 3, the schematic flow sheet of the solid-state material loading feed system that Fig. 1 provides for the embodiment of the present invention; The device structure schematic diagram of the solid-state material loading feed system that Fig. 2 provides for the embodiment of the present invention; The schematic flow sheet of the biomass class solid waste that Fig. 3 provides for the embodiment of the present invention and the useless feeding system of danger.
The biomass class solid waste that the embodiment of the present invention provides and the useless feeding system of danger, its core improvement is, comprises solid-state material loading feed system; This solid-state material loading feed system comprises: stokehold feed bin and feed mechanism; And the quick-break valve be provided with in the path of feed mechanism for blocking flame and flue gas, so that be fed in the process of vapourizing furnace by the solid substances in the feed bin of stokehold, in vapourizing furnace, smoke backflow is to blocking flame and flue gas when feed mechanism.
As can be seen from above-mentioned technical scheme; the biomass class solid waste that the embodiment of the present invention provides and the useless feeding system of danger; in a large amount of external reflux of gasification inner flue gas of the stove to blocking below flame and flue gas when feeding path fast; to prevent the further diffusion of flame and flue gas, the safety effect of proterctive equipment and material (i.e. above-mentioned biomass class solid waste and endanger useless) can be played.
As preferably, also comprise and be provided with temperature measuring equipment in the path of feed mechanism, this temperature measuring equipment is connected with the communication of quick-break valve, and when the measuring tempeature of temperature measuring equipment is higher than preset temperature, quick-break valve blocks the path in feed mechanism.This preset temperature is the critical temperature for judging whether to occur tempering determined according to practical situation.Certainly, a kind of comparatively conventional embodiment is just given at this, those skilled in the art know, and can also judge whether the backflow that there occurs flame and flue gas, do not repeat them here by devices such as the pressure condition in monitoring feeding path or gaseous constituents.
In order to optimize above-mentioned technical scheme further, multiple feeding device is provided with in feed mechanism, multiple feeding device is all connected with temperature measuring equipment communication, and when the measuring tempeature of temperature measuring equipment is higher than preset temperature, the direction order that multiple feeding device advances according to material stops successively, i.e. the in-house each feeding device of feed-disabling (be in the present embodiment successively stopping constant feeder and front-furnace feeding machine) successively.By the above-mentioned mode stopped successively according to material working direction order, can effectively stop subsequent material to enter or close tempered area, and avoid the blocking of material in local, efficient and rational.Temperature measuring equipment can also be connected with the handling equipment communication of preorder, namely by the mechanism of siccative storehouse to material loading in the feed bin of stokehold,, then when the measuring tempeature of temperature measuring equipment is higher than preset temperature, the handling equipment of preorder stops prior to the feeding device of feed mechanism.
