The specific embodiment
With reference to Fig. 2, the utility model car-type efficient energy-saving combustion furnace comprises the body of heater 9 and a combustion control device of symmetrical expression.Body of heater 9 left and right sides are separately installed with gas nozzle 10 and heat-accumulating burner 11, and gas nozzle 10 and heat-accumulating burner 11 are installed in respectively on the sidewall of body of heater 9, and the position that heat-accumulating burner 11 is installed is below the chassis 18 upper surface absolute altitudes of body of heater 9.The outlet of gas nozzle 10 communicates with the inner chamber of body of heater 9 through primary air burning gallery 14 and auxiliary air burning gallery 15.The outlet of heat-accumulating burner 11 communicates with the inner chamber of body of heater 9 through the equal circulation road 16 of auxiliary air, ejection road 17 and auxiliary air burning gallery 15.
With reference to Fig. 3 and Fig. 4, heat-accumulating burner 11 comprises burner body 30 and liner 32 thereof, air collecting chamber 31, heat storage 33 and the high temperature side air collecting chamber 35 that is built into by the burner floater guide block.The burner floater guide block is different from traditional burner block fully, and it has formed the air collecting chamber 35 of heat-accumulating burner high temperature side, and has formed the ejiction opening of air.Air collecting chamber 31 is positioned at the front end of burner body 30.Air intake 12 is positioned on the sidewall of air collecting chamber 31.The inner chamber of burner body 30 is square, and with watering material feeding and high thermal insulation material is done liner 32, heat storage 33 is installed in the liner 32, and high temperature side air collecting chamber 35 is positioned at the end of liner 32, and heat storage 33 is stacked together by some ceramic honeycomb body 34 arrays.Ceramic honeycomb body 34 is a square, and its thickness of honeycomb wall is 0.5～1mm, and the ceramic honeycomb body 34 that is positioned at temperature end adopts the corundum-mullite material to make, and guarantees to have higher refractoriness and good resistance to slag.The ceramic honeycomb body 34 that is positioned at low-temperature end adopts cordierite material to make.The characteristics of cordierite are to have anticorrosive preferably and resistance to thermal shocks being lower than under 1000 ℃ the operating mode.Because honeycomb wall is very thin, depth of penetration heating is little, thereby accumulation of heat, heat release speed are fast, the temperature efficiency height, and be 40～80 seconds commutating period only, helps the temperature field in furnace that burns, and guarantees that material evenly heats.The passage rule of air-flow in the ceramic honeycomb body 34 adopts the gas of elevated pressures frequently to commutate, and has played the effect of blowing the brush passage, stops up so be difficult for producing dust deposit.
The utility model car-type efficient energy-saving combustion furnace adopts the honeycomb ceramics heat storage, and specific area is big, the heat transfer efficiency height, and accumulation of heat speed is fast, and the life-span is long, and maintenance cost is low.Its heat-accumulating process only can be preheating to combustion air and hang down 100 ℃ than furnace temperature, and exhaust gas temperature is less than 150 ℃.Because heat-accumulating burner 11 volumes that adopt are little, site operation, install more convenient.The high temperature section of heat-accumulating burner 11 is embedded in the furnace wall, high insulating effect, and good seal performance, reliable, plant maintenance is few.
The utility model car-type efficient energy-saving combustion furnace when mounted, because being arranged in the both sides of body of heater 9, heat-accumulating burner 11 is positioned at below the chassis 18 upper surface absolute altitudes, the ejection road 17 direction vertically upward, the outlet of high temperature side air collecting chamber 35 with the ejection road 17 outlet be orthogonal.Spraying road 17 top mixed combustions with the coal gas that sprays into after the air preheat, the high-temperature product after the burning vertically sprays in the stove, does not directly wash away material, flame rigidity is little, do not have localized hyperthermia, temperature is even in the stove, material is heated the back discharge from the heat-accumulating burner 11 and the auxiliary flue on opposite.Because exhaust gas temperature is low, operating condition is improved greatly.
Combustion control device is a prior art, referring to Fig. 1 a, comprises air blast 6, air-introduced machine 7, four-way change-over valve 8 and a PLC control system, and four-way change-over valve 8 links to each other by pipeline respectively with air blast 6, air-introduced machine 7 and heat-accumulating burner 11.Four-way change-over valve 8 can realize frequently and commutation fast that commutation was moved when exchange system can realize air and flue gas in 1～2 second.With pipeline that gas nozzle 10, heat-accumulating burner 11 link to each other on be separately installed with the measuring instrument and the by-pass valve control of pressure and flow, measuring instrument and by-pass valve control link to each other with the PLC control system respectively, the PLC control system is gathered pressure and data on flows and is output control signals to air blast 6, air-introduced machine 7 four-way change-over valves 8 and each by-pass valve control, executing agency is by air cylinder driven, stable working is reliable, safeguards simple.The PLC control system has a series of functions such as constant temperature commutation, timing reversing, overtemperature alarm, program behavior, automatic protection.If when exhaust gas temperature meets or exceeds the temperature warning line, system will send alarm signal, and cut off coal gas and air automatically rapidly, system's self-locking prevents to cause device damage because of overtemperature.
Below the course of work of the utility model car-type efficient energy-saving combustion furnace is explained.
Referring to Fig. 1 a, preceding half period, the gas nozzle 10 in left side is in fired state, and the gas nozzle 10 on right side is in closed condition.Combustion air enters left side heat-accumulating burner 11, heat storage 33 heat releases, and combustion air enters combustion furnace and fuel mix burning after being heated to and only hanging down 100 ℃ than furnace temperature; Simultaneously, the flue gas after having burnt enters right side heat-accumulating burner 11, heat storage 33 accumulation of heats, and 90% above heat is absorbed by heat storage 33 in the flue gas, and high-temperature flue gas enters atmosphere through becoming less than 150 ℃ of low-temperature flue gas behind the heat storage 33 by air-introduced machine.When the thermal parameter that reaches certain hour or combustion system reached setting value, referring to Fig. 1 b, control system was sent signal and is driven reversing arrangement, and the duty of left and right side gas nozzle 10 is exchanged, and realized reversing combustion.The alternation that system so goes round and begins again and moves in circles realizes effective utilization of fume afterheat, cuts down the consumption of energy and the discharge capacity of greenhouse gases.The toxic emission temperature is 60 ℃～150 ℃, and air preheating temperature is only than low about 100 ℃ of furnace gas temperature.
Because the bore in ejection road 17 is φ 100mm, preheated air sprays in the auxiliary air burning gallery 15, after the combustion gas mixing burning that in coal gas burner 10, sprays, vertically recline the furnace wall, walk around furnace roof, discharge by heat-accumulating burner 11 along the furnace wall on opposite, so flame does not directly wash away material, add thermal material by radiant heat, there is not the situation of localized hyperthermia, overheated, burning in material.Because the flue-gas temperature of discharging is less than 150 ℃, equipment such as pipeline and four-way change-over valve all are in work under the low temperature, have prolonged the service life of equipment.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; relate under the prerequisite of spirit not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
