Description
Technical field:
The present invention relates to a kind of combustion gas heating pre-mixing device that is applied in the non-oxidation glass foaming furnace.
Background technology:
Existing foamed glass foaming furnace uses conventional wire spiral heating glass cullet and diaphragm capsule, in the furnace chamber oxygen make and the foamed glass surface porcelainization cause the generation of waste product that product percent of pass has only 40% to 75%.In addition, the danger that a large amount of uses of on-the-spot wire spiral have caused the workman to get an electric shock, wire spiral also is very difficult under hot environment simultaneously.The oxygen that exists in the furnace chamber has influenced the formation and the arrangement of foamed glass.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of combustion gas heating pre-mixing device that is applied in the non-oxidation glass foaming furnace, utilize the ratio of pre-mixing device control combustion air and inflammable gas, suppress the existence of oxygen in the products of combustion.The dispersed placement of premix burner improves the temperature homogeneity in the foaming furnace greatly simultaneously, thereby improves the quality product of multicellular glass.
Technical solution problem of the present invention adopts following technical scheme:
Be applied to the combustion gas heating pre-mixing device in the non-oxidation glass foaming furnace, it comprises:
It is parallelly connected at the inlet end of venturi mixer with the inflammable gas pipeline that the combustion air pipeline is set; The exit end of said mixing tank is connected with mixing tank butterfly valve, tensimeter B, PS B mixing tank ball valve and premixed burner in turn, and said premixed burner is installed on the foaming section side wall of furnace;
Be connected with blower fan, air butterfly valve, tensimeter A, PS A and motor-driven control valve in turn on the combustion air pipeline that said mixing tank is communicated with;
Be connected with fuel gas ball valve, strainer, trip valve, tensimeter C, pressure maintaining valve and zero-pressure valve on the said inflammable gas pipeline in turn.
Constructional feature of the present invention also is:
Be provided with explosion-proof apparatus between said PS B and the said mixing tank ball valve.
Also be provided with low pressure switch and high-pressure switch between said tensimeter C and the said pressure maintaining valve.
Said premixed burner is at least two parallel connections, is evenly distributed on the said foaming section sidewall of the furnace body, and is installed in the upper and lower sides of roller-way respectively.
Compared with present technology, beneficial effect of the present invention is embodied in:
The present invention adopts combustion air and inflammable gas mixed firing, can realize homogeneous temp field, high, the save energy of thermo-efficiency, has overcome the defective of foam glass product surface oxidation and abscess ununiformity, and can realize the DCS full automatic control.It can reduce the consumption of electric energy, reduces production costs, and improves product percent of pass, effectively improves the foaming number of unit volume simultaneously, reduces its thermal conductivity.Avoided the danger of on-the-spot electric shock in addition after the gas burner replacement electrically heated.
Description of drawings:
Fig. 1 is a three-dimensional assembling synoptic diagram of the present invention.
Label among the figure: 1 blower fan, 2 air butterfly valves, 3 tensimeter A, 4 PS A, 5 motor-driven control valves; 6 mixing tanks, 7 mixing tank butterfly valves, 8 tensimeter B, 9 PS B, 10 explosion-proof apparatus; 11 mixing tank ball valves, 12 premixed burners, 13 fuel gas ball valves, 14 strainers, 15 trip valves; 16 tensimeter C, 17 low pressure switches, 18 high-pressure switch, 19 pressure maintaining valves, 20 zero-pressure valves.
Below pass through embodiment, and combine accompanying drawing that the present invention is described further.
Embodiment:
Embodiment: referring to Fig. 1,, be provided with tensimeter A3 in the system, PS A4, tensimeter B8, PS B9 and tensimeter C16 by routine.Principle of work of the present invention: the normal temperature combustion air gets into air butterfly valve 2 from blower fan 1, gets into venturi mixer 6 through motor-driven control valve 5 backs, and the zero-pressure valve 20 that is flowing in of combustion air goes out the interruption-forming negative pressure.Inflammable gas is through fuel gas ball valve 13; Strainer 14 arrives pressure maintaining valve 19 with safety cut-off valve 15; Voltage stabilizing adjusts to 5 to 10Kpa through pressure maintaining valve; The inflammable gas of this pressure is in the zero-pressure state after the adjustment automatically through zero-pressure valve 20, and the negative pressure that zero-pressure valve 20 goes out interruption-forming that is flowing in of combustion air sucks thorough mixing in the mixing tank cavity with inflammable gas pro rata.Proportional mixed gas is sent into premixed burner 12 internal combustion through mixing tank butterfly valve 7, mixing tank ball valve 11, can not guarantee that the atmosphere in the foaming furnace is little reducing atmosphere by remaining oxygen.Two staggered up and down being evenly distributed on the foaming section sidewall of the furnace body of premixed burner 12, the flammable premixed gas body sprays at a high speed with annular before burner, realizes the alternate cycles of gas stream in the stove.The mixed gas outlet end of venturi mixer main body is longer than gas inlet end, can guarantee that two kinds of gases have time enough thorough mixing in mixing tank, improves mixed effect.The negative pressure that combustion air flows through the venturi mixer generation sucks the combustion gas in the zero-pressure valve control that realizes the foaming kiln atmosphere in the hybrid chamber.In the outlet of mixing tank explosion-proof apparatus 10 has been installed, can have effectively been prevented the mixed gas tempering.In case the generation tempering, SV cuts out rapidly in system, cuts off gas source.When in a single day tempering takes place in system, explosion-proof apparatus explosion pressure release, gas electromagnetic valve is closed in vernier switch action simultaneously rapidly.Low pressure switch 17 and the high-pressure switch 18 that is provided with in the system is used for the detection of gaseous-pressure fluctuation range; In case unusual fluctuations appear in gaseous-pressure; Be lower than low pressure switch set(ting)value or be higher than the high-pressure switch set(ting)value, SV cuts out rapidly in the system.The premixed burner of foaming furnace adopts Sweet natural gas or LPG as heating energy source, adopts automatic Iganition control system, the on-the-spot temperature of using temperature controller to show each section, and thermopair is given PLC and DCS with temperature signal, realizes the full automatic control of temperature.
