Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Embodiment one
As shown in Figure 1, Figure 2 and Figure 4, the device for liquid waste processing that the embodiment of the present invention one provides, comprise burner 1 and sleeve pipe 4, sleeve pipe 4 is arranged in burner 1 along the axial direction of burner 1, one end of sleeve pipe 4 is positioned at the ejection end 11 of burner 1, the other end connects waste liquid source, and the ejection end 11 of burner 1 passes the kiln head cover 2 of kiln 3 and passes in the negative pressuren zone 31 of kiln 3.
The present invention arranges sleeve pipe passes into kiln path as waste liquid in the burner; gasification oxidation in negative pressuren zone waste liquid directly being sprayed into kiln by the ejection end of burner; the cover gate open that instead of from kiln head cover in prior art enters waste liquid; avoid the process of waste liquid at the internal gasifier of kiln head cover; thus prevent gasify after waste liquid because kiln internal gas pressure fluctuation and along kiln head cover or exist between kiln head cover and kiln gap effusion; protection of the environment, ensures the safety of surrounding people.Meanwhile, in existing burner, carry out sleeve pipe setting, be applicable in the occasion possessing kiln industry on the one hand, save the inner space of kiln on the other hand, easy to use, with low cost.
Preferably, sleeve pipe 4 is positioned at the tube chamber 12 of burner 1.One end end face and the ejection of burner 1 of sleeve pipe 4 hold 11 end faces to align or 11 end faces are held in the ejection that exceeds burner 1.In real work engineering, what the tube chamber of burner was conveying for the wind burnt and coal dust blows and sprays passage, sleeve pipe is arranged in the tube chamber of burner, while kiln combusting coal fines, waste liquid can be sprayed into process, do not hinder the normal work of kiln, as shown in Figures 2 and 3, one end end face of sleeve pipe aligns with the ejection end end face of burner.
Preferably, sleeve pipe 4 is positioned at the tube wall 13 of burner 1.One end end face and the ejection of burner 1 of sleeve pipe 4 hold 11 end faces to align or 11 end faces are held in the ejection that exceeds burner 1.The tube wall of burner is that refractory material is built and formed, sleeve pipe can when making built by burner and tube wall make one, when tube chamber conveying is for the wind that burns and coal dust, by the tube wall of burner, waste liquid can be sprayed into kiln process, and do not hinder the normal work of kiln, as shown in Figure 4 and Figure 5, one end end face of sleeve pipe exceeds the ejection end end face of burner.
Wherein, as shown in Figure 2 and Figure 4, sleeve pipe 4 comprises outside pipe laying 41 and inner fill tube road 42, and the one end in inner fill tube road 42 is stretched in outside pipe laying 41, and the other end is connected with waste liquid source.When kiln normally runs, inner fill tube road is arranged in outside pipe laying, and connects waste liquid source and pass in kiln by waste liquid, according to real work needs, inner fill tube road can also be extracted out very easily from outside pipe laying, not need to change outside pipe laying.
Wherein, waste liquid source is waste liquid holding vessel, and the junction in waste liquid holding vessel and inner fill tube road 41 is provided with force (forcing) pump, and inner fill tube road 41 and waste liquid store tank connected pipeline and be provided with pipeline pipe valve.The junction of inner fill tube road and waste liquid holding vessel arranges force (forcing) pump, makes the waste liquid be drawn out of be sprayed into the negative pressuren zone of kiln by inner fill tube road with certain pressure.
Embodiment two
The method for liquid waste processing that the embodiment of the present invention two provides, comprises the following steps:
S1, outside pipe laying is arranged in burner along the axial direction of burner;
S2, the one end in inner fill tube road is inserted in outside pipe laying;
S3, be connected with waste liquid holding vessel by the other end in inner fill tube road, junction arranges force (forcing) pump, and stores pipe laying pipe valve on tank connected pipeline in inner fill tube road and waste liquid;
S4, startup kiln;
S5, opening conduits pipe valve, open force (forcing) pump, extracted out input inner fill tube road by waste liquid from waste liquid holding vessel.
The present invention arranges outside pipe laying in the burner and inner fill tube road passes into the path of kiln as waste liquid; gasification oxidation in negative pressuren zone waste liquid directly being sprayed into kiln by the ejection end of burner; the cover gate open that instead of from kiln head cover in prior art enters waste liquid; avoid the process of waste liquid at the internal gasifier of kiln head cover; thus prevent gasify after waste liquid because kiln internal gas pressure fluctuation and along kiln head cover or exist between kiln head cover and kiln gap effusion; protection of the environment, ensures the safety of surrounding people.Meanwhile, in existing burner, carry out the setting in outside pipe laying and inner fill tube road, be applicable in the occasion possessing kiln industry on the one hand, save the inner space of kiln on the other hand, easy to use, with low cost.
Further, when kiln is out of service, further comprising the steps of:
S5, stopping force (forcing) pump, closing duct pipe valve;
S6, inner fill tube road to be extracted out from outside pipe laying.
Go wrong when kiln work or according to real work needs, kiln can also be stopped to run, inner fill tube road can be extracted out very easily from outside pipe laying, not needing to change outside pipe laying.
Wherein, one end of outside pipe laying is positioned at the ejection end of burner.The ejection end of burner is positioned at kiln negative pressuren zone, negative pressuren zone be temperature the high-temperature region of about 1700 DEG C, waste liquid is directly sprayed in negative pressuren zone can be vaporized oxidation by the inner fill tube road in outside pipe laying.
Wherein, in S1 step, in the tube chamber that outside pipe laying is installed on burner or build in the tube wall of burner.Outside pipe laying is arranged on the normal work that these two positions all do not affect burner, and saves the furnace inner space of kiln.
In sum; the present invention arranges sleeve pipe passes into kiln path as waste liquid in the burner; gasification oxidation in negative pressuren zone waste liquid directly being sprayed into kiln by the ejection end of burner; the cover gate open that instead of from kiln head cover in prior art enters waste liquid; avoid the process of waste liquid at the internal gasifier of kiln head cover; thus preventing the waste liquid after gasifying because the fluctuation of kiln internal gas pressure along kiln head cover or the gap effusion that exists between kiln head cover and kiln, protection of the environment, ensures the safety of surrounding people.Meanwhile, in existing burner, carry out sleeve pipe setting, be applicable in the occasion possessing kiln industry on the one hand, save the inner space of kiln on the other hand, easy to use, with low cost.When kiln normally runs, filling pipeline one end can connect force (forcing) pump, and the waste liquid be drawn out of sprays into kiln negative pressuren zone, according to real work needs with certain pressure by filling pipeline, filling pipeline can be extracted out very easily from sleeve pipe, not need to change sleeve pipe.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
