Embodiment Construction

[0020] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0021] Such as Figure 1-Figure 3 As shown, a kind of mixing and equalizing structure of the present invention includes an orifice equalizing layer and a foamed metal equalizing layer 1 arranged in the air flow channel 6 perpendicular to the airflow direction, and the orifice equalizing layer is composed of an orifice The static layer 3 of the orifice plate is composed of the static layer 3 of the orifice plate; A plurality of flow equalization holes 5 are set on the corresponding position on the flow layer moving plate 2, and the orifice plate flow leveling layer moving plate 2 can slide along the horizontal and vertical short distances, and after sliding, it can change its position with the orifice plate leveling static plate 3. Corresponding to the degree of coincidence of the equalizing holes.

[0022] The metal foam equalizing layer 1 is ar...

Abstract

The invention relates to a mixing and flow-homogenizing structural body, which includes a pore plate flow-homogenizing layer and a foam metal flow-homogenizing layer which are arranged vertically to the gas flow direction. The pore plate flow-homogenizing layer is composed of a pore plate flow-homogenizing layer fixed sheet and a pore plate flow-homogenizing layer movable sheet, which are arranged adjacently to each other. A plurality of flow-homogenizing pores are formed in corresponding positions on both the pore plate flow-homogenizing layer fixed sheet and the pore plate flow-homogenizing layer movable sheet. The pore plate flow-homogenizing layer movable sheet can slide transversally and vertically at short distance, and when the movable sheet slides, the overlapping ratio of the flow-homogenizing pores in the movable sheet and the corresponding flow-homogenizing pores in the fixed sheet is changed. By means of the combined structure of the foam metal flow-homogenizing layer and the pore plate flow-homogenizing layer. The overlapping ratio of the flow-homogenizing pores in the movable sheet and the fixed sheet can be adjusted, thereby greatly improving flow-homogenizing effect. When being used for removal of NOx through ammonia process under large flue gas load status, gas flows and pressures in multiple chambers can be equalized, and gas flow distribution in single chamber is uniform. Meanwhile, mixing uniformity of ammonia gas or a thermal-desorption gas with flue gas is improved.

Description

technical field [0001] The invention relates to the technical field of medium and low temperature flue gas desulfurization and denitrification, in particular to a mixed flow equalizing structure suitable for an integrated device of medium and low temperature flue gas desulfurization and dust removal, denitrification and thermal desorption. Background technique [0002] When using the reduction method to remove nitrogen oxides in the flue gas, the ammonia reduction method is often used, which is divided into SNCR method and SCR method according to the temperature and the presence or absence of catalysts; the operating temperature of the SNCR method is mostly around 1000 degrees Celsius; the flue gas NH 3 -SCR denitration technology can be roughly divided into three types according to the temperature of the flue gas it treats: the first is high-temperature flue gas denitrification, and the temperature of the flue gas is The temperature of the flue gas is 200-300°C; the third i...
