Bubble cover and bubble cover tower

Abstract

The invention provides a bubble cover and a bubble cover tower, which relates to the technical field of purifying apparatuses. The bubble cover comprises a cover body, wherein the cover body is provided with a plurality of ventilation caps projecting outwardly in the peripheral direction, a ventilation grove is formed in the ventilation cap, the ventilation groove is communicated with the interiorof the cover body, and a notch of the ventilation groove is in a same direction with an air inlet of the cover body; a plurality of vent holes are arranged on the position, close to the notch, of a side wall of the ventilation groove in the peripheral direction of the notch; and the bubble cover tower comprises a tower body and the bubble cover, wherein a plurality of tower plates are arranged inthe tower body in the height direction, each tower plate is provided with a clamping groove, the end portion of a free end of an air ascending pipe of the bubble cover is provided with a clamping arm, and the clamping arm is matched with the clamping groove. By arranging a plurality of ventilation caps, the density of the vent holes in the bubble cover is greatly increased, the cutting effect forsmoke is improved, a contact reaction area between the liquid and the chopped smoke bubbles is increased, and the purifying effect is correspondingly improved.

Description

technical field [0001] The invention relates to the technical field of purification devices, in particular to a bubble cap and a bubble cap tower. Background technique [0002] The flue gas obtained from petroleum or chemical production contains harmful substances or impurities. In order to remove impurities in the flue gas in industry, a bubble cap tower is generally used. The bubble cap tower is equipped with multi-layer horizontal trays. There are several trays The riser pipe for the flue gas to pass through is covered with a bubble cover with tooth gaps or small grooves on the bottom edge, and is equipped with an overflow pipe; during operation, the liquid enters continuously from the upper part of the tower, and descends plate by plate through the overflow pipe. The liquid layer is accumulated on each tray to form a liquid seal, and the flue gas enters from the bottom of the tower, disperses into small bubbles through the tooth gaps or small grooves on the bottom edge o...

Problems solved by technology

[0005] The purpose of the present invention is to provide a bubble cap and a bubble cap tower, to solve the problem in the prior art that in a circular bubble cap or a strip-shaped bubble cap, tooth gaps or small grooves are arranged along the bottom periphery of the side wall of the bubble cap, and the bubble cap The cover occupies a large volume, and the number of tooth gaps or small grooves is small, the contact reaction between the flue gas passing through the tooth gaps or small grooves is not sufficient, and the liquid has a low removal rate of impurities in the flue gas.
