Description
Technical field
The present invention designs a kind of recovery system, particularly a kind of reducing gas automatic recovery system.
Background technology
The raw materials used powder of powder metallurgy is typically all and prepares through reducing process reducibility gas reduction raw material.When also original production for improving production efficiency, generally all need the process passing into excessive reducibility gas to add fast response, thus can produce a large amount of unreacted reducibility gas.It is desirable that from the viewpoint of economic interests and environmental protection two and a large amount of unreacted reducibility gas are carried out recycling.
Existing reducibility gas recovery system is essentially manual or semi-automatic, all there is a need to Attended mode.Its shortcoming is that reducibility gas system pressure is unstable, and pressure regulates and is affected by human factors, and produces operating cost of a relatively high.
Summary of the invention
Goal of the invention: it is an object of the invention to solve existing reducing gas recovery system pressure transient, pressure regulates and is affected by human factors, and needs Attended mode, the problem that operating cost is higher.
Technical scheme: the present invention provides techniques below scheme: a kind of reducing gas automatic recovery system, being sequentially connected with leaching machine, preliminary hydro-extraction device, the first surge tank, one-level dehydration device, two grades of dehydration devices, the second surge tank and reduction furnace, described reducing gas automatic recovery system further comprises switch board；First surge tank is connected to one-level dehydration device by blower fan, and two grades of dehydration devices are connected respectively to the second surge tank and two grades of dehydration device return ducts by three-way solenoid valve；First surge tank, blower fan, two grades of dehydration devices and the second surge tank are connected with switch board respectively；Reduction furnace is connected to leaching machine by exhaust fan.
As optimization, described first surge tank and the second surge tank are equipped with pressure regulator.
As optimization, described two grades of dehydration devices are from becoming internal recycle.
As optimization, described one-level dehydration device adopts cold-heat exchanger.
Operation principle: in reduction furnace, unreacted reducibility gas arrives leaching machine by exhaust fan, enters preliminary hydro-extraction device after leaching machine purifies, and enters first and slow fills tank after preliminary hydro-extraction, and first slow fills on tank equipped with pressure regulator；Blower fan is sent instruction by switch board, controls to cushion the work of tank connected blower fan with first, and the first slow gas filled in tank flows after blower fan supercharging, and blower pressure can be automatically adjusted；Gas after supercharging enters two grades of dehydration devices after the one-level processed of cold-heat exchanger, two grades of dehydrations adopt molecules to sieve technology, improve strainability, in two grades of dehydration devices, heating, blast-cold are automatically controlled by electromagnetic valve, the open and close of each valve are automatically controlled by pneumatic operated valve, and two grades of dehydration devices are from becoming internal recycle；Gas after two grades of dehydrations is automatically controlled by three-way solenoid valve and is partly into equipped with pressure regulator second and slow fills in tank, subsequently enters reduction furnace, forms circulation, a part of enter two grades of dehydration devices and regenerates.
Beneficial effect: the present invention compared with prior art: adopt the mechanism that automatically controls of switch board; realization full-automation can be reduced produce; reduce artificial operation error; improve production efficiency, reached the effect of energy-saving and emission-reduction, protected environment; and sieve dehydration by again carrying out molecule after cold and hot switching dehydration; further improve dewatering efficiency, improve the reducing gas quality of recycling, improve product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
