The utility model has the advantages of: the utility model discloses in, carry out the heat exchange through waste gas and cold water with heat, the waste gas of utilization heat that can be fine, the washing or needs such as washing before the product packaging of product use hydrothermal process, sparingly cost before the water after the heat exchange can be used to electroplate simultaneously.
Description
Technical field
The utility model relates to zinc-plated manufacture field, particularly the zinc-plated exhaust heat utilization system of one.
Background technology
At present, in galvanizing process, usually all can produce a large amount of waste gas with uniform temperature, for this part waste gas, traditional way is: directly by this part toxic emission in air, this is obviously the wasting of resources, and materially increases cost and drop into; And another kind does rule is, heat exchanger is installed in flue to absorb the waste heat in flue gas, the heat obtained can be used as the heat of zinc-plated heating, but only heat exchanger is arranged in flue and also there is safety problem, if continue heating heat exchanger when having a power failure, heat exchanger will occur that because water circulating pump shuts down air pressure is too high, produce the danger of blast.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of zinc-plated exhaust heat utilization system, can be good at well being collected by the heat produced in galvanizing process and again utilizing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of zinc-plated exhaust heat utilization system, and its innovative point is: comprise residual heat flue, thermal conductive pipe and storage tank;
Described storage tank is made up of jointly main water box and secondary water tank, and both being realized by pipeline between main water box with secondary water tank in being communicated with of liquid, in described secondary water tank, the height of liquid is not less than the height of liquid in main water box, and not higher than the height on edge on main water box;
After described thermal conductive pipe runs through main water box from top to bottom, its lower end is connected with residual heat flue, and is interconnected between thermal conductive pipe and main water box, is not communicated with between thermal conductive pipe with residual heat flue, there is several discharge duct in thermal conductive pipe, and discharge duct is connected with residual heat flue.
Further, described thermal conductive pipe has n, and n is the integer of >=1.
Further, the upper end of described main water box is also provided with a steamdrum, this steamdrum has a steam-overflowing tube and an air outlet adapter.
The utility model has the advantage of: in the utility model, by the waste gas of heat and cold water are carried out heat exchange, the waste gas of heat can well be utilized, water simultaneously after heat exchange is also with certain temperature, the cleaning etc. that can be used for electroplating before the cleaning of front product or the packing of product needs to use the operation of hot water, saves cost.
By controlling the height of liquid in main water box and secondary water tank, the steam in main water box can be avoided too much, and cause hypertonia, and then causing the generation of the situations such as blast; By arranging multiple thermal conductive pipe, the utilization rate of waste gas can be improved.
By the setting of steamdrum, timely the steam in main water box can be discharged, simultaneously by arranging air outlet adapter on steamdrum, steam in main water box can be used for the operations such as metal fusible pattern, needed for original metal fusible pattern, steam is provided by boiler combustion, and when providing with boiler, need to use pressure vessel, deposit certain potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of zinc-plated exhaust heat utilization system of the present utility model.
Fig. 2 is the top view of thermal conductive pipe in zinc-plated exhaust heat utilization system of the present utility model.
Detailed description of the invention
