Specific embodiment

With reference to the accompanying drawings and examples, the utility model is described in detail.

Ammonia destruction furnace, referring to Figures 1 and 2, including liner cabinet 1 and the liner being arranged in liner cabinet 12, wherein Multiple heaters 3 are provided in the inner cavity of liner cabinet 1, heater 3 is located at the side of liner 2, and being used for will be in liner cabinet 1 The raised assigned temperature of the temperature of (burner hearth) generates nitrogen and hydrogen so that the ammonia being passed through in liner 2 decomposes.For convenience of to point Dore furnace control is solved, the temperature sensor 4(that should also install on liner cabinet 1 for detecting internal temperature is shown in Fig. 6), temperature Sensor 4 selects K-type thermocouple, and selects digital display output type.

It is opened up on the side wall of liner cabinet 1 referring to Fig. 2 and Fig. 3 for the ease of being replaced when heater 3 is damaged to it There are multiple mounting holes 11, mounting hole 11 runs through the side wall surface of liner cabinet 1, the extraneous inner cavity with liner cabinet 1 of connection.

Heater 3 selects heating wire.The mounting blocks 5 agreed with therewith are provided in mounting hole 11, heater 3 is fixed on peace Block 5 is filled towards 1 inner cavity side of liner cabinet；And mounting blocks 5 are then fixedly connected with handle 50 away from 1 side of liner cabinet.

When the damage of a certain heater 3, user can not have to only need temporarily to heater 3 whole equipment downtime Disjunction electricity then holds handle 50 for the heater 3 of damage and takes out replacement.It is relatively easy to maintenance at this time, and due to replacement Process production can still carry out, so the utility model can not have to user and specially buy another equipment as spare, To reduce production cost.

Referring to Fig. 3 and Fig. 4, interference caused by the setting in order to reduce mounting hole 11, mounting blocks 5 are selected with liner cabinet 1 The same material of wall surface be made, or be set as including at least refractory brick 51, insulating layer 52 and protective layer 53.51, refractory brick In inner cavity of the innermost layer towards liner cabinet 1；Insulating layer 52 is fixed on the inner cavity side that refractory brick 51 deviates from liner cabinet 1, Alumina silicate fibre may be selected；Protective layer 53 is fixed on insulating layer 52 away from 51 side of refractory brick, and galvanized iron sheet may be selected.

Multiple heaters 3 are in be arranged in parallel, and its parallel bus is placed in liner cabinet 1.Staff only need to be to damage at this time Bad heater 3 powers off, and replaces to it and maintenance work can be completed, without shutting down to Integral heating device, to use Better effect.

It is plugged in the side of mounting blocks 5 towards liner cabinet 1 and is fixed with two conductive connecting columns 54, connecting column 54 couples In power supply；Two connecting columns 54 are symmetrical arranged, and towards 1 internal stretch of liner cabinet.Positive negative terminal on heater 3, point Not Tong Guo a high temperature resistant bolt 55 be fixed on corresponding connecting column 54.High temperature resistant bolt 55 wears the wiring of heater 3 simultaneously Column and connecting column 54, and the nut piece 56 for being threadedly coupled adaptation is realized and is fixed.

If heater 3 damages at this time, user only needs rotating nut part 56, and high temperature resistant bolt 55, which is removed, individually to be torn open Replacement heater 3 is unloaded, mounting blocks 5 are replaced together without ining succession, so that using effect is more preferably.

Referring to Fig. 3 and Fig. 4, connecting column 54 plugs one section of elder generation into mounting blocks 5 and extends towards 5 outer surface of mounting blocks, then curved It rolls over and extends towards the side of mounting blocks 5, and extend to the side of mounting blocks 5.Two connecting columns 54 extend the part of mounting blocks 5 Towards on the contrary.

Avris on liner cabinet 1 in mounting hole 11 offers locating slot 12, and locating slot 12 deviates from liner cabinet 1 and court It is in hatch frame to 11 side of mounting hole.

When mounting blocks 5 are connected in mounting hole 11, the connecting column 54 for extending 5 side of mounting blocks is placed in locating slot 12 It is interior, to achieve positioning, fixed for guiding mounting blocks 5 to complete installation.

Referring to Fig. 3 and Fig. 5, conductive plate 13 is mounted in locating slot 12, conductive plate 13 is electrically connected to heater 3 Parallel bus, and it is placed in locating slot 12 close to one end of 1 inner cavity of liner cabinet.When mounting blocks 5 are fixed in mounting hole 11, Connecting column 54(is shown in Fig. 4) conductive plate 13 is contacted at, it is conducted with realizing.Since there is no directly connect on mounting blocks 5 at this time The conducting wire connect, so its installing and dismounting is more convenient, so that using effect is more preferably.Conductive plate 13 is towards in 54 side of connecting column It is recessed, and the column 54 that is connected, to reinforce connection effect.

Referring to Fig. 4, in order to avoid the sealing heat insulation of the 54 excessive interference mounting blocks 5 of connecting column of bending, connecting column 54 Extend the sides of mounting blocks 5 from insulating layer 52 away from the side of liner cabinet 1, and at this time in order to enhance safety, connecting column Insulation sleeve is arranged on 54, only connecting pin exposure, and protective layer 53 is also adopted close to the part of connecting column 54 and is made from an insulative material.

In order to avoid connecting column 54 generates danger towards the side exposure outside liner cabinet 1, contract is formed on mounting blocks 5 The plugging block 57 of locating slot 12 is closed, plugging block 57 is located at connecting column 54 towards the side outside liner cabinet 1.When mounting blocks 5 are installed Afterwards, plugging block 57 is as in locating slot 12, and closed orientation slot 12.

Referring to Fig. 6, the intracorporal temperature of furnace is monitored for convenience, the utility model is equipped with PLC controller 6, PLC 6 electric signal of controller is connected to temperature sensor 4 and heater 3.Staff can feed back according to temperature sensor 4 at this time Temperature detection value is worked using the automatic/semi-automatic control heater 3 of PLC controller 6, to reinforce using effect.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
