Detailed description of the invention
The total design of this utility model is to provide a kind of small-sized household stove, uses airtight burner hearth and the flue of inflection repeatedly, utilizes air-introduced machine to form negative pressure and discharges fume combustion-supporting.Combine accompanying drawing around this design below and introduce seven kinds of embodiments:
The first embodiment: such as Fig. 1, shown in Fig. 2, this negative pressure reverse combustion saving furnace 1 is by shell 2, burner hearth 3, fire door 4, water jacket 5, return pipe 6, fire grate 7, ash door 8, fume pipe 9 parts such as grade form, the hot-water line 12 of water jacket 5 is connected with the circulation pipe of return pipe 6 with warmer two ends, its feature mainly has 2 points: one is the fire door 4 that burner hearth is provided with salable closedown, the structure of fire door 4 is not limited to the form of this figure, but its Main Function is all to load fuel and removing slag to burner hearth, stronger sealing property should be had during closedown, make burner hearth form airtight space as far as possible, this point is that similar stove institute is unwanted.Two is fume pipe 9 inflection coiling repeatedly in the confined space communicated with water jacket 5, and the end of fume pipe 9 connects with the entrance of air-introduced machine 14.
Certainly, the import of fume pipe 9 front end to communicate with burner hearth, and its position can have multiple, and the position of this example preferred fume pipe import is located at the back lower place of burner hearth, namely with the rear corner of ashpit.The most repeatedly extend inflection.
Certainly, the quantity of fume pipe can also be one, it is also possible to is branched.In figure visible, the preferred fume pipe of this example has three, the inflection form of fume pipe and number of times repeatedly can also have multiple, this example preferably upwardly extends by the import of front end, inflection still further below, then upwardly extend, inflection still further below, through three bendings, last outlet with stove outside air-introduced machine entrance connect.
Obviously, a fume pipe can be bent to form repeatedly by a steel pipe, and for the ease of making, it is the bending eliminating fume pipe that this example is recommended, and uses dividing plate 13 to make two fume pipes communicate with end opening, and a steel pipe bending is the frame mode being equal to.
Fig. 3 illustrates a using method of this stove, and the outlet of air-introduced machine 14 enters the heated kang 18 in room by one section of smoke exhaust pipe 15 through wall, and meanwhile, hot-water line 12 and the return pipe 6 of water jacket 5 connect with the circulation pipe at the warmer two ends in room, forms closed circuit.Additionally, connect water tank 17 also by water pipe above stove.Water tank 17 both can be warmer deposit recirculated water and provide certain pressure and volume, can provide the user again bath water.
During use, first open fire door 4 and load fuel to burner hearth 3, after lighting, close fire door 4.Starting air-introduced machine 14, the particularly flue gas of the flame in stove can be passed down through fire grate 7, enters fume pipe 9, then inflection the most repeatedly from import 10, finally discharges from the outlet 11 of fume pipe, then enters heated kang 18 by air-introduced machine 14.Meanwhile, water jacket provides hot water to warmer 18 and water tank 17.
In figure visible, fire grate 7 is the many water pipes communicated with water jacket 5, can increase the heating surface area of water jacket 5.And fume pipe passes through in lying also in the confined space that water jacket 5 communicates, the heat of major part flue gas is exchanged in water.So, major part heat both can have been made to distribute the space in room, heated kang can have been carried out again the heat supply of appropriateness.Avoiding and dispelled the heat by heated kang in the past, thermal loss is big, the phenomenon that the overheated room of a heatable brick bed is the coldest.
If heat supply needs to suspend a period of time, as long as stopping air inducing, in burner hearth 3, immediately enter banking fire state, it is not necessary to using the mode such as firming or fine coal, residual fuel can maintain for a long time and neither burn, the state do not put out a fire.Period also can be released a small amount of heat and be maintained water temperature, keeps stablizing of room temperature.Until being again turned on air-introduced machine, stove fire burns immediately.
Said structure performance is possible not only to be greatly reduced the loss of heat, reduces heat cost, and for realizing automatically controlling providing good condition.The device automatically controlled can have multiple, and simplest mode can control the start-stop of air-introduced machine by water temperature signal, very few used by its cost.Fig. 4 it is also recommended that and a kind of has been associated with controller by pressure transducer and temperature sensor than more preferably device, and controller is associated with the parts such as the motor of air-introduced machine and relief valve again, it is possible to realize higher automatic control process.
The second embodiment: as shown in Figure 5, on the basis of the first embodiment, air-introduced machine 14 outlet or on the smoke exhaust pipe picked out, add cleaner 20, can separate by the composition such as tar in the middle of this flue gas, sulfur dioxide, periodically take out, so can improve the cleannes of discharge, prevent air pollution.Meanwhile, taking out tar can also utilize, and particularly can obtain the selenium element in the middle of coal, and value is higher.
The third embodiment: as shown in Figure 6, on the basis of the first or the second embodiment, the port of export at air-introduced machine picks out loopback pipe 21, and flue gas is transmitted back to burner hearth, carries out second-time burning.So can reduce the combustible in the middle of flue gas further, improve the utilization rate of fuel.Certainly, after loopback pipe is preferably connected on cleaner, being preferably connected on after smoke exhaust pipe is attempted by cleaner, by valve, the valve particularly automatically controlled determines the whereabouts of flue gas.In general, at the beginning of air-introduced machine starts, in stove, the intensity of a fire is relatively low, and the fuel gas accumulation that coal cracks under anoxic conditions the most before this is more, and the value that loopback is fired again is higher, can first carry out loopback, subsequently, in stove, the intensity of a fire is surging, and gas fuel burning is abundant, just can close loopback pipe, and only to heated kang supplied flue gases.
4th kind of embodiment: as it is shown in fig. 7, negative pressure reverse combustion saving furnace 1 described here is identical with the structural principle of the first embodiment, and the structure of the second and the third embodiment is also applied for this example.Except that: fume pipe 9 is not vertically extending inflection, but horizontally extending inflection.Space in figure: the import of fume pipe front end is also the back lower place being located at burner hearth, and the most upwards inflection is the most horizontally extending, repeatedly can directly stretch out shell 2, and connect with the import of air-introduced machine 14 from top after inflection.But so the position of air-introduced machine 14 will be higher.The position being it desired to air-introduced machine 14 is lower, can be as it can be seen, the fume pipe 9 of eminence bends still further below, and the import with air-introduced machine 14 connects in position.
5th kind of embodiment: as shown in Figure 8, changes the position of fume pipe 9 leading inlet 10 on the basis of the first embodiment, and import 10 is relative with the top of burner hearth or middle part, more repeatedly extends inflection, is also advisable with bottom in the position of outlet.This mode makes the flame of fuel upwards burn, it is clear that more meet the rule of burning, but flue gas carries downwards, in the case of airtight condition is preferable, be maintained to the anti-performance burnt.Certainly, the structure of the second and the third embodiment is also applied for this example.
