Description
Technical field
The present invention relates to a kind of quenching gas cyclic utilization system, belong to the resource circulation utilization technical field.
Background technology
At present, nitrogen-cycle installation is not all installed by known gas quenching system, and a large amount of nitrogen just is discharged from after once using, and has so both caused the waste of resource, has increased the quenching cost again.Therefore, be necessary prior art is improved.
Summary of the invention
The purpose of this invention is to provide a kind of quenching gas cyclic utilization system, solved huge this difficult problem of gas quenching technological process nitrogen consumption, when guaranteeing the parts quenching quality, increase resource utilization, can reuse the nitrogen operation of quenching, thereby improved the nitrogen utilization ratio, reduced the gas quenching cost.
The technical solution adopted for the present invention to solve the technical problems is: this quenching gas cyclic utilization system is made up of nitrogengas cylinder, gas-holder 1 and gas-holder 2, quenching work box, strainer, water cooler, air compressor machine, pneumatic tube, ball valve, relief valve, safety valve, vacuum breaker, water discharge valve; Three pneumatic tubes connect three nitrogengas cylinders, three pneumatic tube the other ends connect three manual ball valves, and at three vacuum breaker of manual ball valve one end series connection, with a four-way three pneumatic tubes are linked together, another interface of four-way connects a pneumatic tube again and connects manual ball valve and electrical ball valve in parallel, connect two relief valves in parallel successively with four pneumatic tubes, safety valve, manual ball valve and vacuum breaker, utilize threeway to connect air-supply duct respectively, muffler and gas-holder 1, connect manual ball valve respectively with some pneumatic tubes, tensimeter, the quenching work box, strainer, tensimeter, thermometer, water cooler, gas-holder 2, air compressor machine, oil mist separator takes back gas-holder 1 always.
Tensimeter, safety valve, hydathode etc. all are installed on the described gas-holder, help observing nitrogen gas pressure in the gas-holder, convenient water of discharging in the gas-holder.
On the described gas-holder thermometer is installed, thereby is easy to detection cooling performance.
On the described quenching work box waste gas effuser is installed, and pipe end is uncovered shape, helps the collection water conservancy diversion of waste gas.
The present invention has following advantage and effect: contain a small amount of quenching residue in the nitrogen after the quenching, and temperature is higher, adopt such scheme, nitrogen after quenching can be filtered cooling process, thereby filter the quenching residue, and reduce the temperature to a certain degree, after supercharging, just reached the standard that reuses fully again.This system has fundamentally solved the big defective of gas consumption in the gas quenching technology, by the recycling to waste gas, has both improved resource utilization, has reduced the environmental pollution index again, has both reduced cost, has realized automatization control requirement again.
Description of drawings
Fig. 1 is the present invention's quenching gas recycle system control principle figure;
Among the figure, 1 is nitrogengas cylinder, and 2 is manual ball valve, 3 is electrical ball valve, and 4 is relief valve, and 5 is safety valve, 6 is tensimeter, and 7 are the quenching work box, and 8 is strainer, 9 is thermometer, and 10 is water cooler, and 11 is vacuum breaker, 12 is oil mist separator, and 13 is automatic drain valve, and 14 is air compressor machine, 15 is that gas-holder 1,16 is the manual drainage valve, and 17 is gas-holder 2.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
The quenching gas cyclic utilization system, by ball valve 2 and 3, relief valve 4, safety valve 5, vacuum breaker 11, water discharge valve 13 and 16, gas-holder 117, gas-holder 215, nitrogengas cylinder 1, strainer 8, water cooler 10, air compressor machine 14, quenching work box 7 compositions such as grade, concrete installation method is as follows: be connected on three nitrogengas cylinders 1 with three pneumatic tubes, three pneumatic tube the other ends connect three manual ball valves 2, and at three vacuum breaker 11 of manual ball valve 2 one ends series connection, utilize a four-way that three pneumatic tubes are connected together, another interface of four-way connects a pneumatic tube again, be used to connect the part in parallel of electrical ball valve 3 and manual ball valve 2, connect two relief valves 4 in parallel successively with four pneumatic tubes, safety valve 5, manual ball valve 2 and vacuum breaker 11, utilize threeway to connect air-supply duct respectively, muffler and gas-holder 117, connect electrical ball valve 3 and manual ball valve 2 in parallel respectively with some pneumatic tubes, tensimeter 6, quenching work box 7, strainer 8, tensimeter 6, thermometer 9, water cooler 10, gas-holder 215, air compressor machine 14, oil mist separators 12 etc. take back till the gas-holder 1 always.Tensimeter, safety valve, hydathode etc. all are installed on the gas-holder, help observing nitrogen gas pressure in the gas-holder, convenient water of discharging in the gas-holder.Thermometer is installed on the gas-holder, thereby is easy to detection cooling performance.The waste gas effuser is installed on the quenching work box, and pipe end is uncovered shape, helps the collection water conservancy diversion of waste gas.Manual ball valve and electrical ball valve are formed in parallel, thereby can realize the switching of manually control and electronic control.
The quenching gas recycle system provided by the invention, open the switch of nitrogengas cylinder 1, nitrogen is through behind the relief valve 4, pressure obviously reduces, enter in the gas-holder 116, preparation enters in the middle of the quenching operation, open the switch-valve of gas-holder 1, nitrogen is through behind the depressurization of relief valve 4, enter the quenching work box, treat behind the steady air current workpiece to be put into the quenching work box, the operation of beginning gas quenching, the effuser on the quenching box is collected water conservancy diversion to the nitrogen after quenching, filteration through strainer 8, residue in the waste gas just has been filtered, and again through the cooling effect of supercooler 10, processing back waste gas such as cooling just becomes the nitrogen that can reuse after filtration, enter then in the gas-holder 215, the nitrogen of these recovery is got back in the gas-holder 1 after by the air compressor machine supercharging, continues to identify oneself with the quenching operation, thereby finishes the recycle process of quenching nitrogen.
