Description
Technical field
The present invention relates to industrial vacuum stove technical field of heat exchange devices, be specifically related to a kind of industrial vacuum stove heat-exchanger rig and cooling means thereof.
Background technology
At present, existing industrial vacuum stove lacks effective heat-exchanger rig, generally for and cools, and can increase the length of vacuum drying oven admission line, to increase the gas time of staying in the duct, thus reaches cooling object; The cooling effect of this cooling means is poor, is suitable only for the furnace apparatus that serviceability temperature is lower; Longer admission line takes up room comparatively large simultaneously, causes the volume of equipment to increase, takies larger place and too increase production cost; Last the method can not guarantee that gas cools completely, causes the gas inhomogeneous cooling entering industrial furnace vacuum system, affects the stability and safety of vacuum system.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, for a kind of industrial vacuum stove heat-exchanger rig and cooling means, can effectively improve the situation that in prior art, gas cooling effect is poor, have the advantages that structure is simple, cost is lower, cooling effect is excellent.
The present invention designs and adopts following scheme for this reason:
A kind of industrial vacuum stove heat-exchanger rig, comprises cooling cavities, is separately positioned on inlet channel and the outlet passageway at cooling cavities two ends, and the water filling port be communicated with cooling cavities and delivery port; Described inlet channel communicates with the furnace chamber of industrial furnace, and described outlet passageway communicates with the vacuum system of industrial furnace; Evenly be laid with some tracheaes by flange in described cooling cavities, tracheae two ends described are arbitrarily communicated with outlet passageway with inlet channel respectively; Described water filling port and delivery port are arranged along the diagonal angle, arbitrary cross section of cooling cavities.
Further, described cooling cavities is cylindrical, and described inlet channel and outlet passageway are the hollow hemisphere of both ends open, and one end open and the cooling cavities of described hollow hemisphere connect as one, and the other end opening part of hollow ball is welded with sealing flange.
Further, described sealing flange is CF type flange.
A kind of cooling means of industrial vacuum stove heat-exchanger rig, comprise the following steps: inlet channel and outlet passageway are connected with the furnace chamber of industrial furnace and vacuum system respectively, guarantee water filling port under, delivery port is upper, then in cooling cavities, recirculated water is injected by water filling port, make each tracheae immerse in recirculated water, recirculated water flows out from delivery port gets back to water filling port continuation water cycle process through cooling; After atmosphere in the furnace chamber of simultaneously industrial furnace is recycled water cooling by tracheae, enter the vacuum system of industrial furnace.
Beneficial effect of the present invention is: structure of the present invention is simple, and it is convenient to install, and in cooling cavities, arrange some tracheaes by flange, the two ends of tracheae are connected industrial furnace chamber and vacuum system by the inlet channel at cooling cavities two ends respectively with outlet passageway; Furnace chamber gas is along tracheae while cooling cavities, and by cooling water circulation heat exchange, the continual heat taking away tracheal strips gas, significantly reduces the temperature entering high-temperature gas in industrial furnace vacuum system, thus protection vacuum system.
Accompanying drawing explanation
Be described further with regard to the specific embodiment of the present invention below in conjunction with accompanying drawing, wherein:
Fig. 1 is structural representation of the present invention.
Wherein: 1, cooling cavities, 2, tracheae, 3, inlet channel, 4, sealing flange, 5, flange, 6, water filling port, 7, delivery port, 8, outlet passageway, 9, sealing flange.
Detailed description of the invention
With reference to a kind of industrial vacuum stove heat-exchanger rig shown in Fig. 1, comprise cooling cavities 1, be separately positioned on inlet channel 3 and the outlet passageway 8 at cooling cavities 1 two ends, and the water filling port 6 be communicated with cooling cavities 1 and delivery port 7.
Inlet channel 3 communicates with the furnace chamber of industrial furnace, and outlet passageway 8 communicates with the vacuum system of industrial furnace; Evenly be laid with some tracheaes 2 by flange 5 in cooling cavities 1, the two ends of any tracheae 2 are communicated with outlet passageway 8 with inlet channel 3 respectively; Water filling port 6 and delivery port 7 are arranged along a diagonal angle, cross section of cooling cavities 1, and ensure during use that water filling port 6 is in below, delivery port 7 up.
Cooling cavities 1 is cylindrical, and inlet channel 3 and outlet passageway 8 are the hollow hemisphere of both ends open, and one end open and the cooling cavities 1 of hollow hemisphere connect as one, and the other end opening part of hollow ball is welded with sealing flange 4,9.
Sealing flange 4,9 is the special CF type flange of sealing.
When the present invention makes, first, by the both ends seal welding of flange 5 with cooling cavities 1, all tracheaes 2 all penetrate the relative flange hole in two ends, by the two ends of tracheae 2 and corresponding flange hole seal welding; And then by sealing flange 4,9 respectively with inlet channel 3 and outlet passageway 8 seal welding, finally by inlet channel 3 and outlet passageway 8 and cooling cavities 1 two ends seal welding.
Cooling means of the present invention is as follows: inlet channel and outlet passageway be connected with the furnace chamber of industrial furnace and vacuum system respectively, guarantee water filling port under, the water circulation channel of the gas passage at two ends and cooling cavities inside, upper, is separated by flange and tracheae by delivery port; Then in cooling cavities, inject recirculated water by water filling port, make each tracheae immerse in recirculated water, recirculated water flows out from delivery port gets back to water filling port continuation water cycle process through cooling; After atmosphere in the furnace chamber of simultaneously industrial furnace is recycled water cooling by tracheae, enter the vacuum system of industrial furnace.
The above; be only the better detailed description of the invention of the present invention, but scope is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore scope is as the criterion with the protection domain of claims.
