Description
Technical field
A kind of igniter is the utility model is related to, more particularly to a kind of multiple rows of explosion-proof igniting dress for being used for point biomass fuel
Put.
Background technology
Substantial amounts of stalk is produced in present agricultural production, traditional stalk is mainly handled by the way of burning, both
Air is polluted, again less than effective interests.Straw charring is a kind of its effective utilization, in currently wideling popularize.Straw
Stalk is lighted in thermal decomposition furnace and is carbonized, and current sparking mode typically uses fuel gas（Such as methane, propane, fourth
Alkane etc.）These gas sparking mode are convenient, fast, but it is only applicable to open igniting, and igniting is just deposited in the container sealed
In very big potential safety hazard.When the ratio of gas and oxygen reaches igniting amount and light a fire and do not start or during loss of ignition, can
The amount of combustion gas body and oxygen continuously in supply vessel, is again started up ignition switch, will be flammable in whole container
Gas ignition, and if liberation port can not abrupt release, the generation of explosion accident will be easily caused.
It is another to there is China Patent No. to disclose a kind of igniter for 201320349722.9,2014.1.29, it is especially a kind of to use
New silicon nitride electric igniter on the combustion apparatus using biomass as fuel.It includes shell body, on the shell body,
Through hole is offered along the axis direction of shell body, heater element is equipped with the through hole, one end of the through hole is connected with
Air-supply arrangement.Above-mentioned utility model is directed to because igniter is set in through-holes, have impact on air output, and for a large amount of igniting
When, single igniter is not easy to light biomass fuel.
Utility model content
The defects of in order to overcome above-mentioned prior art, the utility model provide a kind of multiple rows of explosion-proof igniter, this its
Purpose is to improve ignition effectiveness.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of multiple rows of explosion-proof igniter, including igniter, the igniter is interior to be provided with heater element, is set on igniter
There are air inlet and lighting-up tuyere, it is characterised in that：Also include casing, casing is provided with blast pipe, igniter be it is multiple, it is multiple described
Igniter be disposed in parallel in casing, is provided with air dividing plate in the casing, it is multiple described in igniters be located at the one of air dividing plate
Side, the opposite side of air dividing plate and the inwall of casing form gas passage, and the air dividing plate is provided with what is communicated with each igniter
Passage, the passage connect with air inlet.
Described heater element includes silicon nitride heat generating body and heating wire, and the heating wire is located at the interior of silicon nitride heat generating body
Portion, heating wire are connected by wire with the power supply terminal of outside.
Described igniter includes the housing that an inside is cavity, and described heater element be located in housing, air inlet and
Lighting-up tuyere communicates with the cavity of housing.
The utility model has advantages below：
1st, multiple igniters are disposed in parallel in a casing and form multiple rows of explosion-proof igniter by the utility model, use
Same wind regime, for the stalk in pyrolysis oven light a fire simultaneously, improve the success rate of catching fire of stalk, avoid multiple igniting,
Improve ignition effectiveness.
2nd, heater element of the present utility model includes silicon nitride heat generating body and heating wire, and the heating wire is located at silicon nitride hair
The inside of hot body, heating wire are connected by wire with the power supply terminal of outside.Operation principle is exactly that completely avoid the above
Safety defect.It is to discharge the feature of high temperature heat by silicon nitride to substitute fuel gas, silicon nitride heat source body, its body
Product is small, and caloric value is big, moment the air of constant flow can be warmed into more than 1000 DEG C in a specific space, with this source
The continuous high temperature gas flow in source lights furnace interior stalk, and without worrying its security.And the heating number of silicon nitride can
To reach up to ten thousand times.
