Abstract
The invention discloses denitration electric heater unit, including housing, the both ends of housing have air inlet and gas outlet, some deflectors, electric heater and temperature probe are provided with housing cavity, incoming line is provided with the side wall of housing, incoming line is installed with wire, and electric heater connects switch board with temperature probe by wire.The present invention is passed through 300 gases by once heating in air inlet, is heated by electric heater, gas is reached expected temperature, so as to increase reaction efficiency.
Description
Technical field
The present invention relates to a kind of denitration electric heater unit, belong to denitration device field.
Background technology
With the development of society, to environmental requirement more and more higher, denitration is the process for removing the nitrogen oxides in flue gas,
In traditional denitrification process, heating uses heat exchanger, and ammonia is heated into 300 degree by ammonia temperature by gas-gas heat exchanger, due to
Equipment self-defect, temperature are heated to 300 degree or so and can not heated up Shang Qu, and 300 degree of temperature can not be thorough by denitration reaction
Carry out.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of denitration electric heater unit.
In order to achieve the above object, the technical solution adopted in the present invention is：
Denitration electric heater unit, including housing, the both ends of housing have air inlet and gas outlet, are provided with housing cavity
Some deflectors, electric heater and temperature probe, incoming line are provided with the side wall of housing, incoming line is installed with wire, electrical heating
Device connects switch board with temperature probe by wire.
Gas walks S types by deflector in housing cavity.
From air inlet to gas outlet, deflector and electric heater are arranged at intervals.
All deflectors are parallel to each other.
Air inlet and gas outlet are provided with temperature probe, and thermometric spy is provided between adjacent baffle and electric heater
Head.
Switch board is the switch board of rain-proof structure.
The beneficial effect that the present invention is reached：1st, the present invention is passed through 300 gases by once heating in air inlet, passes through
Electric heater heats, and gas is reached expected temperature, so as to increase reaction efficiency；2nd, gas by deflector in housing cavity
In walk S types, the heat time is short and heating is abundant.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, denitration electric heater unit, including housing, the both ends of housing have air inlet 1 and gas outlet 2,
Some deflectors 3, electric heater 4 and temperature probe 6 are provided with housing cavity, from air inlet 1 to gas outlet 2, the He of deflector 3
Electric heater 4 is arranged at intervals, and all deflectors 3 are parallel to each other, and gas walks S types by deflector 3 in housing cavity, during heating
Between short and heating it is abundant, incoming line 5 is provided with the side wall of housing, incoming line 5 is installed with wire, electric heater 4 and temperature probe 6
Switch board is connected by wire, switch board is the switch board of rain-proof structure.
In order to detect the temperature in housing cavity everywhere, prevent too high or too low for temperature, the distribution of temperature probe 6 is as follows：
Air inlet 1 and gas outlet 2 are provided with temperature probe 6, and temperature probe 6 is provided between adjacent baffle 3 and electric heater 4.
Above-mentioned denitration electric heater unit is passed through 300 gases by once heating in air inlet, adds by electric heater 4
Heat, gas is set to reach expected temperature, so as to increase reaction efficiency.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
