Description

A kind of rotor turbulent bed drain measure device

Technical field

The utility model relates to a kind of drainage arrangement, specifically a kind of rotor turbulent bed drain measure device.

Background technique

With the fast development of modern economy, boiler constantly increases, the flue gas being discharged from boiler chimney, serious dirt It is stained with people's lives environment, endangers the health of people.Therefore smoke abatement and dust control, Environmental change are turned waste into wealth, and people is benefited Class just becomes our current major issues in the urgent need to address.

Some areas are to take the lead in reaching particulate matter as defined in national " prevention and control of air pollution action plan " { 2013 } No. 37 texts Average annual concentration index proposes the pollutant catabolic genes indexs such as " ultra-clean discharge ", " 50355 ", and refer specifically to: soot emissions are less than 5mg/m3, sulfur dioxide (SO2) emissions are less than 35mg/m³, discharged nitrous oxides be less than 50mg/m³。

To reach flue dust minimum discharge requirement, existing most common fine dust collecting process technology has wet dust removal technology and rotation Wing turbulent flow bed technique etc..Wherein rotor turbulent flow bed technique is emerging technology, has that construction is simple, investment is low, operating cost is low etc. Advantage, but there is also deficiencies in actual operation for the technology, need to continuously improve.

Rotor turbulent bed is generally mounted in fume wet type desulphurization dedusting defogging equipment, for flue gas secondary desulfuration, remove Dirt, demisting.As shown in Figure 1 and Figure 2, rotor turbulent bed includes module group (1) and the bottom plate (2) for offering several circular holes, module Group (1) is made of the module of several hexagon columns or cylinder, and module bottom is fixedly mounted in the circular hole of bottom plate (1), is Increase bottom plate (1) intensity, bottom are provided with supporting beam (3), and bottom plate (1) is fixedly mounted on the inner wall of apparatus casing (4) On, exist between the rotor turbulent bed module and module of the structure and have the gap, to prevent flue gas from making from the escape of module intermediate gap At flue gas short circuit, the bottom plate (1) of rotor turbulent bed and the inner wall of supporting beam (3) and apparatus casing (4) need to be sealed.To ensure Rotor turbulent bed continuous-stable efficient operation, need to periodically be rinsed, thus flushing water can among two adjacent blocks water, lead It causes rotor turbulent bed performance load to increase, supporting beam and bottom plate is impacted, the service life of equipment is reduced.For above-mentioned existing The problem of having in the presence of technology, a kind of rotor turbulent bed drain measure device of researching and designing is existing in the prior art to solve Problem is very necessary.

Utility model content

The utility model provides a kind of rotor turbulent bed drain measure device, can be by the water on rotor turbulent bed bottom plate It is smoothly discharged, and guarantees that smoke backflow escape phenomenon will not occur, solve the problems, such as water while guaranteeing efficiency of dust collection, drop The load of low rotor turbulent bed, improves the service life of equipment.

In order to solve the above technical problems, the technical solution of the utility model is:

A kind of rotor turbulent bed drain measure device, including drainpipe, the drainpipe are that there are the U-shaped of length difference at both ends Drainpipe, limbers is offered on the bottom plate of the rotor turbulent bed, and the U-shaped drainpipe longer end and the limbers seal Connection；

Further, the longer end of the U-shaped drainpipe is fixedly installed with flange, adopts between the flange and the bottom plate It is fixedly connected with bolt.

Further, the U-shaped drainpipe and the flange are all made of lightweight anti-corrosion material.

Further, the lightweight anti-corrosion material is PVC-U or PP.

After above-mentioned technical proposal, the beneficial effect that the utility model mentions is:

Since drainpipe uses U-shaped drainpipe, after the completion of water is excluded by U-shaped drainpipe on bottom plate, U-shaped drainpipe A part of water inside can be still retained, water seal is consequently formed, the flue gas being flowed into module group is avoided and is returned via U-shaped drainpipe Stream, causes fume treatment insufficient.

It is easy to disassemble since U-shaped drainpipe and bottom plate use flanged joint, easy access and replacement.

It is durable since U-shaped drainpipe and the flange are all made of lightweight anti-corrosion material, and not will increase the negative of bottom plate Load.

Since lightweight anti-corrosion material uses PVC-U or PP, with excellent acidproof, alkaline-resisting, corrosion resistance is not required to appoint What preservative treatment；In addition the tube wall of PVC-U or PP tubing is very smooth, and to the resistance very little of fluid, the coefficient of roughness is only 0.009, conveyance power of water improves 20% than the cast iron pipe of same caliber, improves 40% than pipe of concrete；PVC-U or PP tubing Also there is good watertightness, no matter installation all has good watertightness using bonding or rubber ring connection.PVC-U or The above characteristic of PP material can preferably meet a kind of dewatering needs of rotor turbulent bed drain measure device of the utility model.

In conclusion a kind of rotor turbulent bed drain measure device of the utility model solves rotor turbulent bed bottom plate upper mold Between block and module the problem of the water of gap, a kind of rotor turbulent bed drain measure apparatus structure letter provided by the utility model It is single, it is easy for installation, the water on rotor turbulent bed bottom plate can be made to be smoothly discharged, and smoke backflow escape phenomenon will not occur, The load for reducing rotor turbulent bed, improves the service life of equipment, and ensure that efficiency of dust collection.
