Description

Low NO

Technical field

The utility model relates to a kind of low NOs, belong to fume treatment technical field.

Background technique

Carbon black tail gas fuel value with higher, the burning of carbon black tail gas is burnt using a kind of spiral-flow type at present Device.Carbon black tail gas enters in burner, and flue gas fractional combustion, ignition temperature is lower, and the yield of NOx is fewer, to environment It pollutes also fewer.However existing low NO carries out fractional combustion by the way of eddy flow, controls the production of temperature and NOx Raw amount, but burner structure is complicated, air is low with the mixing efficiency of carbon black tail gas, and mixed effect is poor, influences finally to produce NOx The control of raw amount.

Utility model content

The purpose of this utility model is to solve that deficiency exists in the prior art, and it is simple to provide a kind of structure, operating cost Low, the low NO of high production efficiency is more preferable to the control effect of NOx yield.

The utility model is achieved through the following technical solutions:

I.e. a kind of low NO, including burner box, burner box inner vertical are set there are two riser, and two perpendicular Plate top is linked together by a top plate, and each level in the bottom end of two risers is equipped with a bottom plate, is opened on burner box Equipped with a carbon black smoke entrance, the top of burner box offers carbon black smoke outlet, the two sides inside burner box Three deflectors one are respectively equipped on inner wall, three deflectors one across every side are respectively provided with an ignitor, and two perpendicular Two deflectors two are respectively equipped on the lateral surface of plate, each deflector two is arranged between two adjacent deflectors one, Three aeration tubes are further respectively had on two sides inner wall inside burner box, aeration tube is to be fixed on burner by mounting rack Multiple gas outlets are offered on cabinet wall, on aeration tube, three aeration tubes of every side pass through three induced ducts and set It sets and is connected in the external air-introduced machine of burner box.

The utility model structure is simple, and operating cost is low, and the mixing efficiency of air and carbon black tail gas is high, and effect is good, favorably In raising production efficiency, while being also beneficial to the quantum of output of control NOx.

Further preferably, deflector one, which slopes inwardly, is arranged, and the tail end of deflector one is equipped with reclinate bent angle, water conservancy diversion Plate two is inclined outwardly setting, is conducive to extend incorporation time and the burning time of every level-one carbon black tail gas and air.

Further preferably, the height of bottom plate is lower than the height of bottom aeration tube.

Compared with prior art, beneficial effect possessed by the utility model is:

Specific embodiment

Below against attached drawing, specific embodiment of the present utility model is described in further detail.

A kind of low NO as shown in Figure 1 to Figure 3, including burner box 1,1 inner vertical of burner box are set There are two riser 2, two 2 tops of riser are linked together by a top plate 3, and the bottom end of two risers 2 is each horizontal equipped with one A bottom plate 5 offers a carbon black smoke entrance 4 on burner box 1, and the top of burner box 1 offers carbon black smoke 8 are exported, three deflectors 1 are respectively equipped on the two sides inner wall inside burner box 1, deflector 1, which slopes inwardly, to be arranged, The tail end of deflector 1 is equipped with reclinate bent angle 15, and three deflectors 1 across every side are respectively provided with an ignition power Pole 9 is respectively equipped with two deflectors 27 on the lateral surface of two risers 2, and deflector 27 is inclined outwardly setting, each deflector 27 are arranged between two adjacent deflectors 1, further respectively have three on the two sides inner wall inside burner box 1 Aeration tube 12, the height of bottom plate 5 are lower than the height of bottom aeration tube 12, and aeration tube 12 is to be fixed on burning by mounting rack 13 On 1 inner wall of device cabinet, multiple gas outlets 14 are offered on aeration tube 12, three aeration tubes 12 of every side are respectively drawn by three Air hose 11 is connected with the air-introduced machine 10 being arranged in outside burner box 1.

The course of work:

Carbon black tail gas is entered inside burner box 1 by carbon black smoke entrance 4, carbon black tail gas riser 2 and top plate 3 it Between little by little assemble, after aggregation to a certain extent, carbon black tail gas flows to the lower section of bottom deflector 1, and air-introduced machine 10 is by drawing Air hose 11 and aeration tube 12 introduce air into burner box 1, and air and carbon black tail gas are mixed and burned, after first-stage burning, Carbon black tail gas enters the lower section of second layer deflector 1, burns into the second level, and after secondary firing, carbon black tail gas enters the Three layers of deflector, one 6 lower section, carries out third level burning, finally, after the completion of three-level burning, carbon black tail gas by top charcoal black smoke 8 discharge of gas outlet.

The orientation or positional relationship of the instructions such as term "inner", "outside", "upper", "lower" is in the description of the present invention, It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description the utility model rather than requires the utility model must It must be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
