The automatic reduction gas recycling system is characterized by comprising a sprinkling machine, a primary dehydrating device, a first buffer tank, a primary dehydrating device, a secondary dehydrating device, a second buffer tank and a reduction furnace, which are sequentially connected with one another, and the automatic reduction gas recycling system also comprises a control cabinet. The first buffer tank is connected to the primary dehydrating device through a fan, and the secondary dehydrating device is respectively connected to the second buffer tank and a backflow pipe of the secondary dehydrating device through an electromagnetic three-way valve. The first buffer tank, the fan, the secondary dehydrating device and the second buffer tank are respectively connected with the control cabinet. The reduction furnace is connected to the sprinkling machine through the fan. The automatic reduction gas recycling system is automatically controlled by adopting the control cabinet, so that the automatic production can be realized, the manmade mistake in operation can be reduced, the production efficiency can be improved, the energy-saving and emission-reduction effect can be realized, and the environment can be protected.
Description
Technical field
The utility model relates to 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 all generally to make through reducing process reducibility gas reduction raw material.When going back original production, for enhancing productivity, generally all need to pass into the process that excessive reducibility gas adds fast response, will produce so a large amount of unreacted reducibility gas.From the viewpoint of economic interests and environmental protection two, all require a large amount of unreacted reducibility gas to carry out recycling.
Existing reducibility gas recovery system is manual or semi-automatic substantially, has the Attended mode of needs.Its shortcoming is that reducibility gas system pressure is unstable, and pressure regulates and is affected by human factors, and production operating cost is relatively high.
Summary of the invention
Goal of the invention: the purpose of this utility model is 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 utility model provides following technical scheme: a kind of reducing gas automatic recovery system, connect successively leaching machine, preliminary hydro-extraction device, the first surge tank, one-level dewater unit, secondary dewater unit, the second surge tank and reduction furnace, described reducing gas automatic recovery system has also comprised switch board; The first surge tank is connected to one-level dewater unit by blower fan, and secondary dewater unit is connected respectively to the second surge tank and secondary dewater unit return duct by three-way solenoid valve; The first surge tank, blower fan, secondary dewater unit and the second surge tank are connected with switch board respectively; Reduction furnace is connected to leaching machine by ventilating fan.
As optimization, on described the first surge tank and the second surge tank, be equipped with pressure regulator.
As optimization, circulating dehydration device in described secondary dewater unit adopts.
As optimization, described one-level dewater unit adopts cold-heat exchanger.
Operation principle: unreacted reducibility gas arrives leaching machine by ventilating fan in reduction furnace enters preliminary hydro-extraction device after leaching machine purifies, and enters the first slow tank that fills after preliminary hydro-extraction, and the first slow filling is equipped with pressure regulator on tank; Switch board sends instruction to blower fan, controls and the tank connected blower fan work of the first buffering, and the first slow gas filling in tank flows after blower fan supercharging, and blower pressure can regulate automatically; Gas after supercharging enters secondary dewater unit after the one-level processed of cold-heat exchanger, secondary dehydration adopts the molecule technology of sieving, improve strainability, in secondary dewater unit, heating, blast-cold are controlled automatically by magnetic valve, the open and close of each valve are controlled automatically by pneumatic operated valve, and secondary dewater unit has interior circulation of one's own; Gas after secondary dehydration is automatically controlled a part by three-way solenoid valve and is entered the second slow filling in tank that pressure regulator is housed, and enters subsequently reduction furnace, forms circulation, and some enters secondary dewater unit and regenerates.
Beneficial effect: the utility model compared with prior art: the mechanism that adopts switch board automatically to control; can reduce and realize full-automatic production; reduce artificial operation error; improve production efficiency, reached the effect of energy-saving and emission-reduction, protected environment; and by again carrying out the molecule dehydration of sieving after cold and hot switching dehydration; further improve dewatering efficiency, improved the reducing gas quality of recycling, promoted product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
