Description
Technical field
The utility model relates to the supercritical sewage processing reaction still of environmental technology field, particularly a kind of supercritical sewage processing reaction still nozzle arrangements.
Background technology
Supercritical water oxidation (SCWO) technology be the earliest 20th century the mid-80 proposed by American scholar Modell can fully, up hill and dale by advanced oxidation processes that organic constitution destroys.Point out in one of listed by American National gordian technique six large fields " energy and environment ", the most promising waste treatment technique is SCWO method.
Supercritical water (SCW) refers to that temperature is more than 374.15 DEG C, pressure is more than the water of the special state of 22.12Mpa, the dielectric coefficient of this Water Under reduces greatly, oxygen and gas chromatography matter form homogeneous phase in aqueous systems, eliminate resistance to mass transfer, make the heterogeneous reaction originally occurred between liquid phase, solid phase, gas phase be converted into the homogeneous oxidizing reaction in SCW, speed of reaction is faster, and the residence time is shorter.And scarcely need to use catalyzer, oxidation efficiency is very high, and most of organic clearance can reach more than 99%.In addition, inorganic component and salt solubleness in SCW is very low, almost can Precipitation completely, makes the separation of salt in reaction process become easy.When organic concentration is at 1wt% ~ 2wt%, the oxidation heat liberation of self just can be relied in reaction process to maintain the temperature needed for reaction, and do not need extraneous heat supply, unnecessary heat energy can reclaim.Because reaction is carried out under the environment closed, meet the requirement of totally-enclosed process.Temperature of reaction is far below burning, and the generation of non-secondary pollution thing.
But due to the exacting terms (374.15 DEG C of supercritical water oxidation, 22.12Mpa), a lot of technique is difficult to the operation of held stationary, so be preheating to super critical condition to waste water and oxidant fluid in a lot of technique to enter reactor, the waste water of preheating and oxygenant produce a large amount of calorific losss flowing through in the process of duct, reduce the temperature of waste water and oxygenant, pipeline produces thermal distortion simultaneously, changes the flowing law of waste water and oxidant fluid.
A kind of overcritical water oxidization reactor utilizing auxiliary fuel for supplying heat is disclosed in Chinese utility model patent 201110121463.X, it is formed primarily of kettle, end cap and porous evaporator wall, end cap is provided with fuel core pipe, and be shaped with hot air inlet, autoclave body bottom is shaped with salt relief outlet, it utilizes auxiliary fuel anaplerotic reaction institute heat requirement, without the need in the outer heat of reactor, solves supercritical water reaction systematic economy sex chromosome mosaicism.This utility model is adopt the mode arranging cooling annular groove at end cap lower surface, solves auxiliary fuel, oxygenant and material produce high temperature combustion zone problem at kettle internal end cover lower surface.But it still exists complex structure, installation is wasted time and energy, cannot the problem of maintenance maintenance, and core pipe very easily deformed damaged in the case of a high temperature.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, easy accessibility, is easy to the supercritical sewage processing reaction still nozzle arrangements of inspection and maintenance.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of supercritical sewage processing reaction still nozzle arrangements, it is characterized in that: by pressed joint, upper flange, sleeve, core pipe, nozzle and combustion chamber are formed, the end cap at reactor top is fixedly mounted with described upper flange, the center of upper flange is longitudinally installed on after core pipe is coaxially installed in sleeve inner, pressed joint screw thread is installed on upper flange and is fixed by sleeve, enclosed space is formed between core pipe and sleeve, oxidant channel is left between sleeve and upper flange, core pipe passes the bottom screw thread fixed installation nozzle of sleeve, the reactor end cap of nozzle periphery is provided with combustion chamber, longitudinal fuel inlet is shaped with at pressed joint, upper flange is shaped with oxidant inlet, this oxidant inlet is communicated with described oxidant channel.
And described upper cartridge periphery is shaped with back taper chuck, upper flange is corresponding is shaped with taper chuck, and sleeve and upper flange realize conical surface seal by pressed joint.
And described core tube wall interval is shaped with multiple annular shoulder contacted with sleeve lining.
And described outer nozzle wall even circumferential interval is shaped with multiple support rim contacted with Inner Wall of Combustion Chamber.
Advantage of the present utility model and beneficial effect are:
1, this supercritical sewage processing reaction still nozzle arrangements, sleeve and core pipe adopt welding process to be coaxially fixedly mounted with to be connected, nozzle is connected with core gas thread, total is inserted in upper flange, tighten pressed joint by sleeve and upper flange conical surface seal, only need back out pressed joint, can take out total, this mounting structure is fast very convenient.
2, this supercritical sewage processing reaction still nozzle arrangements, core tube outer surface and sleeve interior surface form airtight space, when the flow in fuel of preheating is through core pipe thin long eyelet, effectively can reduces the heat exchange with the external world, avoid calorific loss.
3, this supercritical sewage processing reaction still nozzle arrangements, core tube wall interval is shaped with multiple annular shoulder contacted with sleeve lining, outer nozzle wall even circumferential interval is shaped with multiple support rim contacted with Inner Wall of Combustion Chamber, this structure reduces the amplitude of core pipe vibrations, is conducive to the stability keeping fuel flowing.
4, the utility model design science is reasonable, has that structure is simple, easy accessibility, and being easy to the outstanding advantages of inspection and maintenance, is a kind of nozzle arrangements with the supercritical sewage processing reaction still of higher innovation.
