The utility model can be in the normal productive process of Muffle furnace, guaranteeing under device security and the condition easy to maintenance, utilize the heat energy in the high-temperature flue gas of its generation, water is converted into the steam of purposes at the heat exchanger place, obtain the low-temperature flue gas of compliance with environmental protection requirements simultaneously, realized the energy-conservation again purpose of environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model will be further described explanation.As shown in Figure 1, the utility model discloses a kind of energy-saving Muffle furnace, comprise body of heater 1 and be located at first flue 2 of its end, the bottom of body of heater 1 be provided with one advance fire grate 11 that coal uses and with help the clean-burning air blast 12 of coal, comprise that also one is connected in the heat exchanger 3 on first flue 2 and connects the low temperature flue 4 of the heat exchanger other end, heat exchanger has a water inlet 34 and a steam (vapor) outlet 32.Described heat exchanger 3 two ends respectively are provided with a smoke box 31, and are provided with also anti-sealing that is communicated with two smoke boxes and the many hollow metal pipes 33 that flue gas contacts 31 of two smoke boxes in heat exchanger.The described first flue inwall is provided with refractory masses 21, and described refractory masses 21 is fixed on the first flue inwall by a plurality of palladium nails 22, and this cloth refractory masses can reduce high-temperature flue gas greatly through out-of-date thermal loss.In addition, expand for absorbing in the high-temperature flue heating and cooling process, described first flue 2 also is provided with the thermal expansion compensator 24 that prevents that stress causes in the flue heating and cooling process flue from tearing, and is provided with one at first flue and conveniently carries out the flue deashing and prevent the ash-removing mouth 25 that dust deposit in flue stops up.
Maintenance for convenience, and make full use of the periphery setting of existing Muffle furnace, described first flue 2 is provided with first flashboard 23 that is used to close or open first flue, described body of heater 1 also connects to be located at underground second flue, 5, the second flues 5 and to be provided with second flashboard 51 that is used to close or open second flue.Described first flue is positioned at the upside of body of heater 1, and second flue is positioned at the downside of body of heater 1.Described underground flue end is connected in is located at ground chimney 7, the other end of the low temperature flue of described heat exchanger end is connected on second flue of chimney below, and locates to be provided with the air-introduced machine 8 of a help air draft above the low temperature flue and the second flue junction.
The coal of coming in through fire grate 11 fully burns under the effect of air blast, in producing, the body of heater 1 of Muffle furnace can produce a large amount of high-temperature flue gas, because first flashboard 23 is opened, second flashboard 51 cuts out, so at this moment high-temperature flue gas can introduce water by water inlet 34 in first flue 2 enters the heat exchanger of being made up of many hollow metal pipes 31 3, water runs into the metal tube 31 of filling high-temperature gas, being heated is converted into steam, is discharged by steam (vapor) outlet 32 and does collection, is used for purposes such as pickling, phosphatization.The heat of the high-temperature flue gas in the metal tube is taken away the back temperature by the water of outside and is descended rapidly, is generally about 200 degree, then by low temperature flue 4, passes through second flue 5 through the effect of air-introduced machine 8, is drained in the atmosphere through chimney 7 then and goes
Have one deck to have a plurality of palladiums to follow closely 22 securing refractory masses 21 on the inwall of first flue 2 of energy-saving Muffle furnace, falls reduced before the temperature of assurance high-temperature flue gas entered in the heat exchanger 3 through second flue 2.
Energy-saving Muffle furnace of the present utility model, when breaking down, heat exchanger does maintenance or renewal part, first flashboard 23 can cut out, the high-temperature gas of opening 51 such bodies of heater 1 generations of second flashboard enters second smokejack 5, be drained in the atmosphere through chimney 7 again, certainly, meet environmental protection requirement more, the flue gas that leaves heat exchanger can also be carried out desulfurization and dedusting after discharge by chimney 7 for making flue gas.
