Description

A kind of new online backwash separates candle filter

Technical field

This structure belongs to separation technology field, for the separation and collection of catalyst in reactor, belongs to large-scale candle filter, Specifically a kind of new online backwash separates filter element, for fields such as Coal Chemical Industry, fine chemistry industry, petrochemical industries.

Background technology

In the production technology of petrochemical industry, organic chemical industry, fine chemistry industry and Coal Chemical Industry, there are various reactions to need Take catalyst to accelerate the speed of chemical reaction.In this kind of use, substantially there is two ways, one kind is that catalyst is consolidated Fixed, working solution flows through catalyst and is reacted；Also one kind be catalyst with working solution mix flowing carry out being catalyzed it is anti- Should；For latter event, after completion of the reaction, there are two kinds of processing methods：One kind is that reactant liquor output is arrived into reactor outside, Catalyst is intercepted with filter, then net liquid output, the dope containing catalyst sends reactor back to pump and pipeline again Reuse；There is a kind of inside for being to be placed in filtering technique reactor again, directly catalyst is intercepted, net liquid row Go out, catalyst is stayed in reactor, work on；The shortcoming of cloth set candle filter is that filter cloth cover usage cycles are short, easily blocking, Unstable cost height of efficiency etc..

The content of the invention

This new online backwash separates candle filter is for above-mentioned deficiency：The original design cloth shell type candle formula that is adopted as is filtered Device, the shortcoming of cloth set candle filter is that filter cloth cover usage cycles are short, easily blocking, unstable cost height of efficiency etc., and the design New ON-LINE SEPARATION candle filter can overcome disadvantage mentioned above；Filter efficiency can reach more than 98% or higher, using the longevity Life improves 3-4 times, greatly saves the time for changing filter element, reduces use cost.

By retort cylinder, backwash tube, frame of filter element, filter O-ring, some filter elements, upper cover plate, hanger, floral disc, current stabilization Pipe etc. is constituted；In retort cylinder, reactant liquor enters filter element cartridge interior, flows through filter skeleton for device integral installation, leads to Cross skeleton flange and retort external connection enters subsequent processing, while that what is arranged on filter exists as dry filter element intercepts catalyst In tank, work on；When the filter element of filter is blocked, when filtration resistance increases, backwash Gutron clear liquid backwash filter element recovers normal Filter；This device belongs to large-scale candle filter, for fields such as Coal Chemical Industry, fine chemistry industry, petrochemical industries；Larger pressure can be born Difference；Other filter normal filtrations can not be affected with single backwash；Filter element is demountable structure, is easy to keep in repair and changes.

Innovation main points：

1st, installed on filter floral disc using some filter elements, increase effective filtration area；

2nd, filter element is compressed by top board, it is integrated with filter skeleton；

3rd, barretter in skeleton, can make backwash liquor pressure uniformly to element back-wash filter, it is ensured that backwash effect；

4th, backwash tube is set, in same retort during backwash, the work of other filters is not affected, reaction is allow even Continuous work；

5th, filter element adopts section for arbitrary shape；

6th, the material of filter element is metal or nonmetallic materials.

Technical scheme

This new online backwash separates candle filter, O-shaped by retort cylinder A, backwash tube 1, filter skeleton 2, filter Circle 3, filter element 4, upper cover plate 5, hanger 6, floral disc 7, barretter 8, wing plate 9 are constituted；It is characterized in that：In filter floral disc 7 up to The N number of filter element 4 of few welded and installed；Backwash tube 1 is inserted into one end that barretter 8 exposes, filter skeleton 2 is fixed on by threaded connection Bottom center；Frame of filter element 2 is fixedly connected again by flange with retort cylinder A；Hanger 6 is welded by central canal with floral disc 7 Integral, floral disc 7 is integrally welded with filter skeleton 2；Same bolt of crossing on upper cover plate 5 is fixed and clamped filter element 4；Filter skeleton 2 On be symmetrically welded with the wing plate 9 of four, cloth stream backwash liquid is played a part of on the inside of retort cylinder A；Filter O-ring 3 with The installing hole fitted seal of retort cylinder A, is conducive to backwash effect；Described same bolt excessively is referred to can be also cross multilamellar The bolt of different parts, actually according to the bolt of thickness characteristics non-standard de-sign length.

In retort, reactant liquor enters filter element cartridge interior to the integral installation of this device, filter skeleton is flowed through, by bone Frame flange and retort cylinder A external connections enter subsequent processing, at the same arrange on filter as dry filter element intercepts catalyst In retort cylinder A, worked on by pipeline circulation in retort cylinder A；When the filter element of filter is blocked, filtration resistance is crossed When power increases, backwash Gutron clear liquid backwash filter element recovers normal filtration；Larger pressure reduction can be born；Can be with single backwash not shadow Ring other filter normal filtrations；Filter element is demountable structure, is easy to keep in repair and changes.

Beneficial effect

This device belongs to super-huge candle filter, for fields such as Coal Chemical Industry, fine chemistry industry, petrochemical industries；Can bear compared with Big pressure reduction；Other filter normal filtrations can not be affected with single backwash；Filter element is demountable structure, is easy to keep in repair and changes； Installed on filter floral disc using some filter elements, increase effective filtration area；Filter element is compressed by top board, with filter skeleton one Change；Barretter makes backwash hydraulic coupling uniformly to element back-wash filter in skeleton, it is ensured that backwash effect；Backwash tube is set in same retort In backwash when, do not affect the work of other filters, allow reaction continuously to work.
