Candle filter

Abstract

The invention discloses a candle filter, which comprises a tank body, a protective cover and a filter core. The inside of the tank body is provided with a liquid inlet chamber and a filter chamber, and an annular support plate is arranged between the liquid inlet chamber and the filter chamber to filter The interior of the chamber is detachably installed with a filter element, the top of one side of the filter chamber is fixedly connected with a recoil pipe, the top of the other side of the filter chamber is fixedly connected with a clear liquid outlet, and the tank above the clear liquid outlet is fixedly connected with a The filter chamber is connected to the overflow pipe, and the overflow pipe is extended from the end of the filter chamber to the inside of the liquid inlet chamber, the outer side of the tank body is provided with a protective cover, and the inner wall of the protective cover is evenly provided with electric heating tubes, and The top of the tank body is detachably mounted with an upper cover through bolts. The present invention is convenient to control the optimum temperature inside the tank body during the filtration process. Since the cohesive force between molecules decreases when the temperature rises, the viscosity coefficient will decrease and the fluidity will increase, thereby effectively increasing the liquid flow velocity and improving the filtration efficiency. .

Description

technical field [0001] The invention relates to the technical field of industrial filtering devices, in particular to a candle filter. Background technique [0002] In petrochemical, organic chemical, fine chemical and coal chemical production processes, there are many reactions that require the use of catalysts to speed up the chemical reactions. There are basically two ways to use catalysts: one is that the catalyst is fixed, the working The liquid flows through the catalyst to react; there is also a catalyst that flows together with the working fluid to carry out the catalytic reaction. For the latter case, after the reaction is completed, there are two treatment methods: one is to output the reaction liquid to the outside of the reactor, use a filter to intercept the catalyst, and then output the net liquid, and then pump the concentrated liquid containing the catalyst And the pipeline is sent back to the reactor for reuse; another is to place the filter device inside t...

AI Technical Summary

Problems solved by technology

[0003] For the filter device placed inside the reactor, candle filters are generally used. Existing candle filters generally include core candle filters and laminated candle filters. The filtration area of ​​this candle filter is Small, and due to the existence of liquid viscosity, the internal friction of the fluid is large. In the case of no external energy supplementation, the flow speed is slow, the filtration efficiency is low, and there is no backwashing function; continuous work cannot be achieved, and it is inconvenient to replace the filter element
