Technical field
The present invention relates to a kind of multi-functional tubular type stove of coking product processing usefulness, be applicable to the operation of the needs heating such as crude benzol distillation, ammonia still process and sulphur ammonium drying of coking industry.
Background technology
The organic media tube furnace often is used to the heat supply of chemical unit, and in coal tar product field, the use of tube furnace is general; Like ammonia still process, steaming benzene, sulphur ammonium drying; The tube furnace equipment of domestic most enterprises all is that special stove is special-purpose, only is used for heating like tube furnace in the coking steaming benzene operation and steams used recycle oil of benzene and superheated steam, for the crude benzol distillation process provides heat; And a stove can only heat a kind of medium; When needs heat multiple medium, need many stoves to unite use, the limitation and the unicity that cause equipment to use.
Summary of the invention
The object of the present invention is to provide a kind of multi-functional tubular type stove; To above-mentioned situation, but the invention provides the tube furnace of a kind of heat cycles washing oil, steam, three kinds of media of water, this device has improved the tube furnace internal structure; Heating load in the stove is adjusted again and carried out effective distribution; Realized a stove three usefulness, realized many posies stable heating, produced continuously.
The present invention solves the technical scheme that its technical problem takes: a kind of multi-functional tubular type stove; Comprise the tube furnace body; Said tube furnace body is made up of supporting leg, furnace chamber, burner and chimney; And the upper and lower of said furnace chamber is respectively convection section and radiant section, it is characterized in that, in said convection section, is provided with S shape circuitous circulating washing oil preheating pipe and jet chimney; The import of two pipelines and outlet are positioned at the outside of body of heater; Said radiant section is provided with circuitous hot water pipeline and the circulating washing oil pipeline of two circle S shapes from inside to outside, and the import of two pipelines and outlet are positioned at the outside of body of heater, and between the import of said circulating washing oil pipeline and the outlet of circulating washing oil preheating pipe, installs and prop up a pipeline and connect.
Said circulating washing oil pipeline is close to the radiant section furnace wall cloth and is put, and in the vertical direction becomes S shape back and forth circuitous, and 20cm-30cm at interval between the two adjacent vertical tubes, removes benzene steaming tower after medium is heated to 200 ℃-230 ℃ in the circulating washing oil ducts; Said hot water pipeline in the vertical direction becomes S shape circuitous; And interval 30cm-35cm between the two adjacent vertical tubes; And hot water pipeline and the dislocation of circulating washing oil pipeline are arranged, hot water pipeline row inner ring, circulating washing oil row of conduits outer ring; Two circle spaced radial 25cm-30cm, the hot water in the hot water pipeline deliver to sulphur ammonium and ammonia still by outlet after being heated to 120 ℃ superheated water; Jet chimney adopts the horizontal coil pipe of S shape to arrange, and steam is heated to form 350 ℃ superheated steam and removes benzene steaming tower in pipeline.
The invention has the beneficial effects as follows: tube furnace according to the invention is the improvement to the conventional tubular stove; Increased water coil at radiant section; Be used to steam the benzene except that heating above circulating washing oil and steam, also introduced the third medium, realized space-heating system to the multiple operation heat supply through transformation; Thereby saved floor space greatly, also improved the utilization rate of equipment and installations and the thermal efficiency.
The core of this device is a tube furnace, not only can supply crude benzol distillation heat and heating steam, can also supply ammonia still process, sulphur ammonium drying, sulfur melting kettle, evaporating kettle and pipe tracing etc.This multi-functional tubular type stove makes heating equipment more concentrated, and equipment investment significantly reduces, and thermal loss reduces relatively in the heat supplying process, and heat capacity is more efficient, and is more energy-conservation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 launches sketch map for hot water pipeline;
Among the figure: 11 supporting legs, 12 furnace chambers, 13 burners, 14 chimneys, 15 convection sections, 16 radiant sections, 2 jet chimneys, 31 circulating washing oil preheating pipes, 32 circulating washing oil pipelines, 33 pipelines, 4 hot water pipelines.
The specific embodiment
Like Fig. 1, shown in Figure 2,
A kind of multi-functional tubular type stove; Comprise the tube furnace body; The tube furnace body is made up of supporting leg 11, furnace chamber 12, burner 13 and chimney 14, and the upper and lower of furnace chamber is divided into convection section 15 and radiant section 16 by function, and these are the essential structure of tube furnace.Improvements are the arrangement form of pipeline, and are specific as follows:
15 are provided with the circuitous jet chimney 2 of S shape in convection section; The import of pipeline and outlet are positioned at the outside of body of heater; Jet chimney adopts the horizontal coil pipe of S shape to arrange, and steam is heated to form 350 ℃ superheated steam and removes benzene steaming tower in pipeline, realizes heating and generates the effect of superheated steam.
In convection section 15, be provided with the circuitous circulating washing oil preheating pipe 31 of S shape, be positioned at the upside of jet chimney, the import of circulating washing oil preheating pipe 31 and outlet are positioned at the outside of body of heater.Another section circulating washing oil pipeline 32 is close to the radiant section furnace wall cloth and is put; Circulating washing oil pipeline in the vertical direction becomes S shape circuitous; And interval 20cm-30cm between the two adjacent vertical tubes; The import of circulating washing oil pipeline 32 is positioned at the outside of body of heater with outlet, between the import of circulating washing oil pipeline and the outlet of circulating washing oil preheating pipe, a pipeline 33 is installed and is connected.The import of circulating washing oil self-loopa washing oil preheating pipe gets into, successively through pipeline and a circulating washing oil pipeline, through preheating and heat after the circulating washing oil medium be heated to 200-230 ℃ and remove benzene steaming tower then.
