Water distribution device for particle activated coke adsorption tower

Abstract

The invention discloses a water distribution device for a particle activated coke adsorption tower. The water distribution device is integrally arranged into a three-stage water inlet structure, including a first-stage water inlet layer, a second-stage water diversion layer and a third-stage water diversion layer, wherein the first-stage water inlet layer is a center bin with a tubular structure;a water inlet is formed in the top of the center bin; the second-stage water diversion layer is characterized in that water diversion bins are symmetrically arranged on two sides of the center bin anda plurality of water diversion arms are symmetrically distributed on two sides of the water diversion bin; water distribution arms which are arranged below the water diversion arms and are communicated with the water diversion arms are arranged on third-stage water diversion layer; a plurality of water distribution ports are uniformly distributed in the water distribution arms. The water distribution device disclosed by the invention has the advantages that sewage entering an adsorption tower can uniformly enter a coke layer with particle activated coke, and filtering and adsorbing propertiesof the particle activated coke are sufficiently improved; uniform flowing of the activated coke in the adsorption tower can be realized, and the filtering and adsorbing properties of the particle activated coke are improved; electrochemical corrosion of the activated coke and a stainless steel material can be prevented.

Description

technical field [0001] The invention belongs to the field of granular activated coke adsorption towers, in particular to a granular activated coke adsorption tower cloth water device. Background technique [0002] Under the mixed condition of granular activated coke and sewage, there are many problems in the water distribution of the adsorption tower. The resistance of the water changes continuously. During the operation, due to the filtering effect of the granular activated coke itself, the suspended solids in the sewage are intercepted. The regular reduction will result in the reduction of partial water flow or not enough water, which will affect the adsorption effect of granular activated coke, and cause the active coke in the adsorption tower to fail to achieve sufficient adsorption saturation and lose its adsorption capacity. [0003] During the use of active coke, normal coke turning and coke washing will have uneven fluidity, overall flow or central flow, resulting i...
