[0031] Instance

[0032] A specific example of the process of the present invention will be described in further detail below with reference to the accompanying drawings. The filtering process of the present invention is composed of four main processes: adding auxiliary agent-filtering-stripping filter cake-gas, solid and liquid separation. Such as figure 1 with figure 2 As shown, the present invention mainly consists of a solid-liquid mixer 4, two multi-tube filters 1A and 1B, a three-phase separator 6, a tail gas absorption tank 2, a raw water pump 3, a mud pump 5, a regulating valve, and multiple pipelines Connection composition.

[0033] The specific structure of the solid-liquid mixer 4 is as follows image 3 , 4 , As shown in 5.

[0034] The integrated solid-liquid mixing equipment consists of four parts: powder bin 4-21, powder conveying meter 4-11, dispersing assembly 4-9 and mud bin 4-18. The powder bin consists of cylinder 4-6, head 4-1, manhole 4-4, fence 4-5, vent 4-...

Abstract

The present invention discloses delayed coking waste water filtering technological process and apparatus. The delayed coking and waste water filtering process includes four steps of: throwing assistant, filtering, stripping filter cake and gas, liquid and solid separation. The main apparatus includes solid-liquid mixer, multiple-pipe filter, triphase separator, tail gas absorbing tank, etc. The present invention has isolating film formed on the filtering medium with the assistant; two filters switching mode; mixed gas and liquid phase blowing or dripping washing for stripping filter cake; combined three phase separation; and automatic control with controller. The present invention has the features of simple structure, convenient operation, high automation, high filtering precision, small covered area, etc. and is used in eliminating coke powder from delayed coking waste water.

Description

technical field [0001] The invention relates to a delayed coking wastewater filtering process and device, in particular to a filtering process and device for removing coke powder contained in delayed coking wastewater. Background technique [0002] Delayed coking wastewater contains a small amount of coke powder and other suspended particles. During the subsequent stripping process, coke powder is easy to heat and coke in the stripper, which affects the separation efficiency of the stripper. In severe cases, the stripper will be blocked and cannot operation, affecting the normal operation of the stripper. Therefore, it is best to filter the delayed coking wastewater before steaming. [0003] Filtration process is an important chemical unit process. The more common filtration processes and equipment include pressure filtration equipment, plate and frame filters, drum filters, centrifugal filters, etc. that need to provide external energy, and sand filters that rely on gravi...
