The specific embodiment
Shown in the structural representation of Fig. 1 the utility model low pressure hot dirty gas injection apparatus, low pressure hot dirty gas injection apparatus of the present utility model comprises: burner 1 has spout 10 and outer wall 11; Coal gas chamber 2, it is provided with the gas exit 2b in gas inlet 2a and the feeding spout 10; Air distribution tube 3 is sleeved on gas exit 2b outside, and the one end is connected with the outer wall 11 of burner 1, and the other end is fixed on the coal gas chamber 2 by sealing plate 3b, and air distribution tube 3 is provided with air inlet 3a.
Wherein, low pressure hot dirty gas injection apparatus of the present utility model also comprises injection airduct 4, and it is penetrated the air port and is placed in the coal gas chamber 2 and aims at spout 10.
The utility model utilizes the pressure-air of injection airduct 4 ejections that the low pressure hot dirty gas in the coal gas chamber 2 is carried out injection one time, utilization is carried out secondary injection by the pressure-air that air inlet 3a enters to the coal gas by gas exit 2b ejection, thereby increase the kinetic energy that mixes of low pressure hot dirty gas and combustion air, improve the burning impulsive force of low pressure hot dirty gas, make combustion flame stable.
As shown in Figure 1, low pressure hot dirty gas injection apparatus of the present utility model comprises burner 1, has spout 10 and outer wall 11, the through hole of spout 10 for being surrounded by outer wall 11; The top in coal gas chamber 2 is provided with gas inlet 2a, the one end is provided with the gas exit 2b that feeds in the spout 10, make the low pressure hot dirty gas that enters by gas inlet 2a spray into spout 10 by gas exit 2b, coal gas chamber 2 end relative with gas exit 2b sealed by bonnet 2c, is fixed with the connecting plate 20 that is sleeved on the outer wall on the outer wall in coal gas chamber 2; Air distribution tube 3, be sleeved on the outside of the gas exit 2b in coal gas chamber 2, its top is provided with air inlet 3a, one end of air distribution tube 3 is fixed on the outer wall 11 of burner 1, make air distribution tube 3 be communicated with spout 10, the other end of air distribution tube 3 is provided with the sealing plate 3b that is sleeved on 2 outer walls of coal gas chamber, between the connecting plate 20 on the outer wall in sealing plate 3b and coal gas chamber 2 gasket seal is set, sealing plate 3b is connected with connecting plate 20 bolts, thereby the other end of air distribution tube 3 is fixedlyed connected with coal gas chamber 2.
