(1) technical field
The present invention relates to the waste incineration and generating electricity technical field, be specially a kind of smoke gas flow distributor of rotating spraying reaction tower.
(2) background technology
The garbage incinerating power plant flue gas treating process has various ways at present, and wherein a kind of form is rotating spraying formula semidry method flue gas treating process.The key technology of this technique is that the High Rotation Speed sprayer reaches the smoke gas flow distributor that is complementary with it, and the deacidification effect of flue gas depends on the degree of atomization of absorbent and the uniformity that flue gas stream is distributed.Traditional flue gas stream distributor rotary sprayer that just simply flue gas led, flue gas stream distributed uniform degree is not high, greatly affected the deacidification efficiency of this technique, cause the flue-gas temperature skewness because of the flue gas maldistribution simultaneously, directly affect service life and the effect of reaction tower back deduster.
(3) summary of the invention
For the problems referred to above, the invention provides a kind of smoke gas flow distributor of rotating spraying reaction tower, this device makes flue gas stream distributed uniform in reaction tower, and flue-gas temperature is evenly distributed.
Its technical scheme is such: it comprises air inlet duct, and described air inlet duct is isobaric sped structure, and the outlet of described air inlet duct links to each other with airflow guiding device.
Its further technical scheme is:
Described airflow guiding device comprises the housing that is made of upper sealing panel and lower seal plate, is disposed with first group of guide vane and second group of guide vane in the described housing; Described first group of guide vane has two at least, radially is evenly arranged; Described first group of guide vane is according to radially iso-curvature is crooked; Described first group of guide vane has 16; Described second group of guide vane has two at least, radially is evenly arranged; Described second group of guide vane is crooked according to axial iso-curvature; Described second group of guide vane has 10; The exit of described second group of guide vane is provided with conical pipe; Described housing middle part is provided with spraying protection cylinder and supports.
The present invention is designed to isobaric sped structure with air inlet duct, makes flue gas produce identical pressure in each cross section of air inlet duct, guarantees the air-flow distribution uniformity in each cross section; The outlet of air inlet duct is linked to each other with airflow guiding device, by airflow guiding device with the flue gas rotary sprayer that leads, improved the contact-making surface of flue gas and absorbent, increased the time of reaction, greatly reduce the discharge capacity of the harmful sour gas of flue gas, flue-gas temperature is distributed more even, reduce the impact on reaction tower subsequent technique equipment; And in the airflow guiding device, the exit of the setting of two groups of guide vanes and second group of guide vane is provided with conical pipe, has further guaranteed the flue gas rotary sprayer that leads is reduced flue gas significantly on the impact of reaction tower subsequent technique equipment.

(5) specific embodiment
As shown in Figure 1 and Figure 2, the present invention is a kind of smoke gas flow distributor of rotating spraying reaction tower, and it comprises air inlet duct 1, and air inlet duct 1 is installed on the reaction tower cylindrical shell 10.Air inlet duct 1 is isobaric sped structure, and flue gas 9 enters isobaric spiral air inlet duct 1 and produces preliminary rotary speed, produces identical pressure in air inlet duct 1 each cross section simultaneously, thereby guarantees the air-flow distribution uniformity in each cross section.Near being provided with ring smoke outlet 3 on the interior plate 2 of base plate, this outlet 3 links to each other with airflow guiding device 11 on the air inlet duct 1, with the even importing airflow guiding devices 11 of flue gas 9.
As shown in Figure 3, airflow guiding device 11 comprises the housing that is made of upper sealing panel 12 and lower seal plate 13, is disposed with first group of guide vane 6 and second group of guide vane 7 in this housing.The housing middle part is provided with spraying protection cylinder and supports 14, and referring to Fig. 1, spraying protection cylinder supports rotary sprayer support and protection cylinder 4 are installed in 14, and rotary sprayer 5 is installed in the bottom of rotary sprayer support and protection cylinder 4.
As shown in Figure 4, first group of guide vane 6 has two at least, has 16 in the present embodiment, radially is evenly arranged; And first group of guide vane 6 is according to radially iso-curvature is crooked.First group of guide vane 6 can make flue gas 9 produce radially rapidly and uniformly rotation.
As shown in Figure 5, second group of guide vane 7 has two at least, has 10 in the present embodiment, radially is evenly arranged; Second group of guide vane 7 is crooked according to axial iso-curvature.Second group of guide vane 7 can be derived airflow guiding device with flue gas, to prevent flue gas Yong Sai in airflow guiding device, guarantees that the circulation of flue gas is smooth and easy.
Again referring to Fig. 1, be provided with conical pipe 8 in the exit of second group of guide vane 7 of airflow guiding device 11, by the spray disk spraying of conical pipe 8 with flue gas 9 guiding rotary sprayers 5.
Operation principle of the present invention is: flue gas 9 enters isobaric spiral air inlet duct 1 and produces preliminary rotary speed, produces identical pressure in air inlet duct 1 each cross section simultaneously, thereby guarantees the air-flow distribution uniformity in each cross section; The flue gas 9 of uniform flux and uniform pressure is further accelerated flow rotation speed by first group of guide vane of airflow guiding device 11 with flue gas 9; Second group of guide vane 7 of airflow guiding device 11 derived flue gas 9 downwards, guarantees that the circulation of flue gas 9 is smooth and easy; By the spray disk spraying area of conical pipe 8 with flue gas 9 guiding rotary sprayers 5, make the more violent collision of flue gas 9 and absorbent, improve the surface area of absorbent and flue gas, the reaction contact-making surface of increase and sour gas, thus improve deacidification effect.
The present invention has improved the contact-making surface of flue gas and absorbent, has increased the time of reaction, greatly reduces the discharge capacity of the harmful sour gas of flue gas, flue-gas temperature is distributed more even, reduces the impact on reaction tower subsequent technique equipment.
