Abstract
The utility model discloses an adjusting rod of a gas injection box. The adjusting rod comprises a long rod and a conical gas cap. The long rod is provided with a first end and a second end in the axial direction. The conical gas cap is connected with the first end of the long rod and coaxial with the long rod. The combustion wind injection volume can be adjusted when the adjusting rod of the gas injection box is matched with the gas injection box, and therefore a reaction area reaches a window at the optimal combustion temperature, the combustion degree is improved, and higher denitrification efficiency and higher boiler combustion efficiency are achieved.
Description
Technical field
The utility model relates to a kind of gas nozzle adjusting device, relates in particular to a kind of adjusting rod.
Background technology
The nitrogen oxide producing in boiler combustion is the large and more unmanageable atmosphere pollution of harm.Along with " fossil-fuel power plant atmospheric pollutant emission standard " promulgation (GB13223-2011), the NOx(nitrogen oxide that China produces fire coal) emission request stricter, reduce in boiler smoke NOx and be the important and difficult task of Industrial Boiler industry smoke gas treatment.In order to make the NOx in boiler smoke controlled, major measure is to reduce and reduce the generation of NOx from source.The process of removing NOx in combustion product gases is also referred to as denitrification process.Adopting at present denitration means is the most widely Researched of Air Staging Combustion Burning Pulverized Coal technology.
Researched of Air Staging Combustion Burning Pulverized Coal is by changing air supply mode, control the distribution of furnace air amount, reach the technology that NOx generates that suppresses.By Researched of Air Staging Combustion Burning Pulverized Coal will be in stove burning be divided into two combustion phases, i.e. combustion with meagre oxygen stage and burn the stage.Coal dust combustion with meagre oxygen, the growing amount of inhibition NOx, this combustion phases is sent into by control combustion air quantity, makes burning under reducing atmosphere, and some is reduced to N the NOx that now early stage, burning generated
2.Subsequently, burning the stage, unburned fuel mixes with burnt wind in upper furnace and realizes completing combustion.
But, actual while utilizing air classification technology, burnt wind can not be in time consumingly with fuel mix, this makes to burn process and has certain delay, causes combustion lag, causes efficiency of combustion to decline, unburned carbon in flue dust raises.
Utility model content
The purpose of this utility model is to provide a kind of adjusting rod of gas jet box, spray the emitted dose of burnt wind by this adjusting rod energy adjustments of gas jet box, thereby make conversion zone reach best combustion temperature window, improve and burn degree, realize higher denitration efficiency and boiler combustion efficiency.
According to above-mentioned utility model object, the utility model proposes a kind of adjusting rod of gas jet box, it comprises:
One stock, it in axial direction has a first end and one second end;
One conical cowl, it is connected with the first end of described stock, the coaxial setting of described conical cowl and stock.
The adjusting rod of gas jet box described in the utility model is located at the nozzle of gas jet box, control the axial distance of conical cowl and spout by controlling the axial displacement of described stock, thereby realize the opening and closing of spout, and control the degree opening and closing to regulate air quantity.
Further, in the adjusting rod of gas jet box described in the utility model, be arranged with a middle back-up ring on the first end of described stock, described conical cowl is fixedly connected with middle back-up ring, and described middle back-up ring is set to move along the axial direction of stock.
Further, in the adjusting rod of above-mentioned gas jet box, the first end of described stock also fixed cover is provided with a front back-up ring and a rear back-up ring, and described front back-up ring and rear back-up ring are located at respectively front and the rear of described middle back-up ring along the axial direction of stock.This front back-up ring and rear back-up ring define the scope that conical cowl moves in the axial direction with respect to stock.
Further, in the adjusting rod of gas jet box described in the utility model, the second end of described stock is fixed with one handle.The setting party of handle the adjustment operation of the axial displacement of operating personnel to stock.
Further, in the adjusting rod of above-mentioned gas jet box, described handle is fixedly installed on the second end of described stock by two back-up rings that front and back arrange respectively of the axial direction along stock.
Further, in the adjusting rod of gas jet box described in the utility model, be also provided with a bindiny mechanism on described stock, this bindiny mechanism is located at the near middle of stock axial direction.This bindiny mechanism can be for being fixed on adjusting rod on gas jet box.
Further, in the adjusting rod of above-mentioned gas jet box, described bindiny mechanism is bolt.
Further, in the adjusting rod of gas jet box described in the utility model, the central angle angle of described conical cowl is 75-120 °.
Adjusting rod and the gas jet box of the gas jet box that the utility model provides are used in conjunction with, can regulate burnt wind spray angle, thereby make conversion zone reach best combustion temperature window, improve and burn degree, realize higher denitration efficiency and boiler combustion efficiency.
