Description

A kind of absorption tower overflow system with defoaming device

Technical field

The utility model relates to wet process of FGD field more particularly to a kind of absorption tower overflow systems with defoaming device System.

Background technique

In the operational process of wet method fume desulfurizing system, the slurries generation blistering in absorption tower has become a kind of more general All over the phenomenon that, be mainly manifested in the Liquid level on absorption tower in normal value, the slurries in tower but pass through overflow pipe stream come out, The slurries that overflow goes out are mainly grey black Pao Droplets.Absorption tower slurries foaming phenomena is to FGD(Flue gas Desulfurization flue gas desulfurization) stable operation of device brings many detrimental effects: absorbing tower liquid-level is unable to maintain that It is normal horizontal, the environment around foam pollution absorption tower to overflow, while also causing the waste of slurries.

Conventional outflow pipe in absorption tower is there are two types of form at present: first is that the design of overflow pipe top has exhaust outlet, although can be with Prevent siphonage, once but slurries blistering will be overflowed outward and drift by exhaust outlet, cause tower body equipment and week Surrounding environment seriously pollutes.Second is that overflow pipe is not designed with gas vent, and although generating foam can flow in trench, absorption tower slurries Siphon overflow very likely occurs, causes bigger environmental pollution, more likely influences unit safety operation.

Utility model content

The purpose of the utility model is to provide a kind of absorption tower overflow system with defoaming device, will solve the prior art Middle absorbing tower liquid-level is unable to maintain that the normal level the technical issues of；And solve the problems, such as that the prior art easily causes slurries to waste.

To achieve the above objectives, the present invention adopts the following technical solutions:

A kind of absorption tower overflow system with defoaming device, it is characterised in that: including overflow pipe component and process water Main pipe, the overflow pipe component include overflow pipe and the overflow pipe branch pipe being connected to overflow pipe side wall, the overflow pipe top Outlet end is equipped with foam trap ontology, and the foam trap housing cover is equipped with Dense mesh screen；The foam trap ontology For the rectangular or columnar structured of top surface opening, foam trap ontology bottom surface is connected to overflow pipe, top surface opening；

It hangs above the foam trap ontology equipped with spray head, the spray head is located at the vertical axis of foam trap ontology On line, spray head is 10-15cm at a distance from Dense mesh screen, and the spray head is connected to by pipeline with process water main pipe, and the pipeline leans on One end of nearly process water main pipe is equipped with process water controlled valve.

It is further preferred that the foam trap ontology is the rectangular bubble that length × width × height is 600 × 400 × 400mm Foam collector.

Further, the foam trap ontology center of gravity and the overflow pipe center of circle are located in same vertical lines.

Further, the foam trap ontology is made of steel carbon, and inside is painted with anti-corrosion scale.

Further, it is 10mm-20mm seamless steel pipe that the pipeline, which is diameter,.

In addition, the Dense mesh screen density is not less than 800 mesh/100cm², Dense mesh screen surrounding passes through edge-pressing strip and bolt and bubble The fastening of foam collector ontology.

It is further preferred that the overflow pipe and overflow pipe branch pipe are connected to AFT tower and absorption tower respectively.

Compared with prior art the utility model have the characteristics that and the utility model has the advantages that

The utility model solves the not set bubble elimination device of the prior art, stable operation of the foam easily to FGD device The technical issues of bringing adverse effect, the utility model structure is simple, low manufacture cost, and operation and maintenance are convenient, and defoaming effect is aobvious It writes.

The utility model has the characteristics that safety, is applicable in, and has good promotion and practical value, after extensive popularization and application Good economic benefit can be generated.
