Embodiment 1

As shown in Figure 1 and 2, a kind of new ceramics igniter, including tubular shell 10, interior tubular shell 10 is waste combustible Gas is logical.Several ceramic heating tubes 20 positioned at diametric plane are evenly distributed in tubular shell 10 from top to bottom.

In the present embodiment, the ceramic heating tube 20 has four, so that igniter realizes four sections of igniting, four ceramics The midpoint of heat-generating pipe 20 is located at same vertical plane, the setting direction of four ceramic heating tubes 20 make four ceramic heating tubes 20 from In rice font from the point of view of overlook direction.When the igniting network that rice font is constituted arranges waste combustible gas from the bottom up, successively lead to Four sections of igniting, and the igniting network Jing Guo rice font are crossed, so that burning is more abundant.

It further, further include 301 group 30 of air supply pipe, 301 groups of air supply pipe in the present embodiment in order to burn more sufficiently 30 tilt upward the air supply pipe 301 of setting including air inlet pipe 303, ring pipe 302 and four.The lower end of air supply pipe 301 is in ring It is uniformly distributed on shape pipe 302 and is connected to ring pipe 302, the higher-end of air supply pipe 301 is located in tubular shell 10, and in tubular The same diametric plane of shell 10 is uniformly distributed；The higher-end of air supply pipe 301 is located at the lower section of ceramic heating tube 20.Ring pipe 302 is also It is connected with air inlet pipe 303, air inlet pipe 303 is equipped with supercharging air pump, and the entrance of air inlet pipe 303 is that trumpet type is open, convenient for pressurization Air pump absorbs air, and increases after its pressure after the conveying of ring pipe 302 from four air supply pipes 301.302 housing of ring pipe By bracket or it is welded on 10 outer wall of tubular shell.

There are two the effects that 301 group 30 of air supply pipe, one guarantee no matter waste combustible gas uninterrupted when, ceramics hair The pressure of 20 lower section of heat pipe is greater than atmospheric pressure, prevents flame from flowing backward, causes danger.Second is that air supply pipe 301 tilts upward, when out When the high-pressure air pressure come is higher than waste combustible gas pressure, pressure-air impacts waste combustible gas one, makes to have leisure Gas and waste combustible gas mixing obtain more uniformly, and burning is further abundant.

The connection type of 301 group of 30 each pipeline of air supply pipe belongs to the prior art, can be that welding can also be with flanged joint.

Ceramic heating tube 20 includes the heater in tubular dielectric shell and tubular dielectric body, and the heater is conductive pottery Porcelain, tubular insulator are preferably quartz glass or ceramic material.Conductivity ceramics has good oxidation resistance, and service life is more It is long.

Heater is located in tubular dielectric body, and with the coaxial setting of tubular insulator.The both ends of tubular insulator are provided with Opening protrudes into conducting element in tubular dielectric body and connect with heater.

In the present embodiment, the conducting element is preferably electric wire, by resistant to high temperature extraordinary exhausted between electric wire and heater Edge silica gel bonding.It is wherein cohered between heater and tubular insulator also by insulation silica gel, so that its heater is stablized.

In the present embodiment, fire resistant electric wire is 200 DEG C of high temperature resistant or more of fire resistant electric wire.

Two end pipe of ceramic heating is mounted in tubular shell 10 by mounting base 50, and mounting base 50 is equipped with and tubular dielectric Body end mouth matched mounting groove 501 is additionally provided with the cable hole 502 of perforation mounting base 50 in mounting groove 501, enables electric wire from walking String holes 502 is pierced by, and 50 two sides of mounting base are equipped with the otic placode for being provided with bolt hole, so that mounting base 50 detachably connects with tubular shell 10 It connects.The one side that mounting base 50 and otic placode touch tubular shell 10 is that can cooperate the cambered surface of 10 inner wall radian of tubular shell.

It is equipped with bolt hole in mounting base 50, is mounted by bolt hole mounting base 50 on the shell, to realize ceramics Heat-generating pipe 20 and it is external between fixation.

Tubular shell 10 be equipped with corresponding cable hole 502, electric wire is involved outside tubular shell 10, electric wire with High-temperature resistant seal ring is equipped between tubular shell 10, the electric wire being drawn off is connected to power supply by switch, so that switch can be controlled Whether circuit processed is connected to, and realizes igniting to control ceramic heating tube 20 and whether generate high temperature.Power supply has apart from tubular shell 10 Certain distance.

In the present embodiment, conductivity ceramics is Filamentous or column.Conductivity ceramics and tubular insulator in the present embodiment are all The prior art, therefore do not elaborate.

The working principle of the present embodiment is as follows: tubular shell and waste combustible gas exhaust pipe are connected by flange seal It connects, exhaust pipe arranges waste combustible gas upwards, and waste combustible gas successively passes through four sections of ignition, and due to waste combustible Pass through in the channel of installation heat-generating pipe inside igniter between gas, therefore the contact area of waste combustible gas and heat-generating pipe It is larger, and the heat-generating pipe in four sections of heating constitutes a meter font, to carry out full combustion to waste combustible gas.

Embodiment 2

The present embodiment the difference from embodiment 1 is that, the present embodiment be equipped with guide frame, to ceramic heating tube 20 Installation is oriented to, and is guaranteed when installing ceramic heating tube 20, as long as and then guide frame, just can be guaranteed four ceramic heatings Pipe 20 constitutes rice font network.

Guide frame includes the vertical guide groove 40 on 10 inner wall of tubular shell, the both ends of any one ceramic heating tube 20 With there are two guide groove 40, mounting base 50 can be slided in guide groove 40, and 40 top of guide groove is not closed, and be convenient for ceramic heating The mounting base 50 at 20 both ends of pipe skids off slide-in from top, realizes installation and removal.

Otic placode is not located in guide groove 40, vertically goes up suitable position when sliding into mounting base 50 in guide groove 40, It will be connected to power supply after electric wire spreading (as needed can not also spreading) again after electric wire is involved from cable hole 502.Pass through otic placode It is fixed in peace tubular shell 10 with bolt.

Embodiment 3

As shown in figure 3, the present embodiment the difference from embodiment 1 is that, due to during installation, inevitable electric wire and heater are It is pierced by after connecting, and from mounting base 50, then electric wire can be interposed between mounting base 50 and guide groove when mounting base 50 is started Between 40, substantially without influence in tangible sliding process, but in order to preferably slide fluency.Mounting base 50 is close to guide groove 40 face is equipped with the cabling channel 503 of indent, and electric wire can be embedded in the cabling channel 503 of indent, is easily installed the sliding of seat 50.Fig. 3 In do not mark otic placode.

According to above-described embodiment, the utility model can be realized well.It is worth noting that being based on said structure design Under the premise of, to solve same technical problem, even if that makes on the utility model is some without substantive change or profit Color, the essence of used technical solution is still as the utility model, therefore it should also be as the protection model in the utility model In enclosing.
