Embodiment

[0054] Example: see attached figure 1 , The invention is a multi-stage combined high-efficiency heat exchange and dust removal device.

[0055] The multi-stage combined high-efficiency heat exchange and dedusting device of the present invention, the tower internals arranged from bottom to top include in turn: (1) a louver gas distributor 1 (such as Figure 2-a , 2-b ), the distance between the center line of the gas distributor and the top of the uppermost herringbone baffle is 1.4 to 2 times the diameter of the gas inlet; (2) 6 to 10 layers of herringbone baffles with openings are set in the initial washing section 2 (such as Figure 3-a , 3-b ), the width of the baffle plate of the herringbone baffle is 1 / 8~1 / 15 of the tower diameter, and the distance between each layer of herringbone trays is 600-900mm; (3) The initial washing section washing liquid is set above the herringbone baffle Distribution pipe 3 (such as Figure 4 ), the distance from the centerline of the fe...

Abstract

The invention relates to a multistage combined type high-efficiency heat-exchanging dust-removing device, a dedusting tower comprises, from bottom to top in turn, a tower bottom gas distributor, an initial washing section tower tray, an initial washing section washing liquid distribution tube, a secondary flushing section grid filler, a secondary flushing section anti clogging liquid distributor, a secondary flushing section feeding distribution tube, a fresh washing liquid feeding distribution tube and a swirl plate demister. A dedusting tower circulating liquid is divided into two parts to enter the tower, one part is pumped onto the upper part of a herringbone baffle plate by a pump, and the other part is pumped onto the upper part of the grid filler by the pump. Through use of the multistage combined type high-efficiency heat-exchanging dust-removing device for treatment of a dust-containing gas, the amount of the fresh washing liquid can effectively be reduced, energy and material consumption are saved, by use of the multistage combined type high-efficiency heat-exchanging dust-removing device for treatment of the dust-containing gas, the washing liquid as a tower bottom liquid phase can be recycled, the liquid is basically sealed and recycled, and the washing heat-exchanging can be effectively improved. The multistage combined type high-efficiency heat-exchanging dust-removing device is every low in pressure drop, the whole tower pressure drop is less than 3kPa, and the anti blocking performance is strong.

Description

technical field [0001] The invention relates to a washing and dedusting tower, in particular to a device used for washing, dust removal and heat exchange in petrochemical, coal chemical, steel and other fields. Background technique [0002] In petrochemical, coal chemical, steel and other fields, in the process of gas purification, there are high requirements for washing, dust removal, and cooling, such as desulfurization towers, flue gas scrubbers, quenching towers, etc., the processed substances are usually dirty and contain A large amount of dust or tar requires the tower internals of the tower to have strong anti-clogging performance. In coal chemical industry, empty tower spray is used for gas cooling and dedusting, and the cooling effect is relatively poor, which makes the subsequent purification work more difficult. [0003] The purpose of the present invention is to solve the problems of unsatisfactory dust removal, washing and cooling effects, large solvent consump...
