Abstract

The utility model belongs to the technical field of the waste water treatment equipment, specifically relating to an ultrasonic air floating device. The purpose of the utility model is to provide an ultrasonic air floating device to overcome the problems of insufficiently ideal treatment effect and low treatment amount due to slag pollution which can be easily caused in the prior art. In order to solve the problems existing in the prior art, the ultrasonic air floating device employs the following technical scheme: the ultrasonic air floating device comprises a housing within which an ultrasonic breaking chamber, an air floating separation chamber and a water collecting chamber are included, wherein a drain outlet and a water outlet pipe are arranged at the bottom of the water collecting chamber, and wherein a plurality of water collecting pipes are communicated with the water outlet pipe within the water collecting chamber; a water outlet groove is formed on the upper portion of the outer side of the housing and communicated with the water outlet pipe; a slag-out groove is communicated with the upper portion of a side face of the water outlet groove; and a slag outlet is communicated with the slag-out groove.

Description

A kind of UW air supporting device

Technical field

The utility model belongs to the sewage treatment equipment technical field, is specifically related to a kind of UW air supporting device.

Backgroundfield

Blue charcoal waste water is the waste water that produces in coal system semicoke product and the quenching process, its COD, BOD, SS, phenol, NH ₃-N, wet goods content are very high, and complicated component is changeable.Secondly wherein organic pollutant is main with phenol compound, accounts for the over half of total organic matter, also comprises the heterogeneous ring compound of polycyclc aromatic compound and nitrogenous, oxygen, sulphur etc.; Inorganic pollutant is main with prussiate, sulfide, ammonium salt mainly.Blue charcoal waste water is a kind of typical high-concentration organic sewage difficult to degrade, and intractability is very big.

According to the difference of coking industry investment and production mode, coking chemical waste water is divided into two kinds of the lighter metallurgical coke of pollution (coke) waste water and with serious pollution semicoke (blue charcoal) waste water.The production of the extensive property of metallurgical coke is in the majority, and investment puts in place, and the sub product (coal tar, coke(oven)gas, crude benzol etc.) that is produced in the production process has been carried out comprehensive recovery and utilization, and therefore, pollutent obviously reduces in the waste water of its generation.Such waste water is general only through carrying out biochemical treatment after the simple pre-treatment (oil removal and water quality and quantity are regulated), realizes standard wastewater discharge or recycling.Semicoke is blue charcoal, is raw material because it adopts non-caking coal and weakly caking coal, the production technique of middle low-temperature pyrolysis; Add production-scale limitedly, the deficiency of investment does not comprehensively reclaim and utilizes the sub product in the production process; Therefore; The a large amount of poisonous and hazardous material that produces in its process of coking all is dissolved in the waste water, makes such contaminated wastewater substrate concentration quite high, has also improved the intractability of such waste water simultaneously greatly.At present, blue charcoal waste water has become one of used water difficult to degradate of generally acknowledging both at home and abroad.

Adopt conventional treatment technology to handle blue charcoal waste water; It is very high all the time that it goes out water concentration, is difficult to reach emission standard, therefore in order to reach effluent index; Must take a kind of method to interrupt or crack macromole and hard-degraded substance in the organic pollutant, make its removal that is decomposed.At present, ultrasonic technology is used very wide in this type of problem of solution.Like the patent No. is a kind of UW air supporting oil eliminator of " 200420079136.8 "; Be to adopt UW to add air floating method to abolish macromolecular oil; Its structure is: comprise that UW cracks chamber, air flotation separating chamber and collecting chamber, be provided with sewage draining exit and rising pipe in the collecting chamber bottom.Owing to also contain a large amount of bits in the water of entering rising pipe, therefore cause the slag pollution easily and cause treatment effect not ideal enough, simultaneously because the UW stack can cause that secondary cracks, so treatment capacity is little.

Summary of the invention

The purpose of the utility model provides a kind of UW air supporting device, is prone to cause slag to pollute and causes the problem that treatment effect is not ideal enough and treatment capacity is little with what overcome that prior art exists.

In order to solve the problem that exists in the prior art; The technical scheme that the utility model adopted is: a kind of UW air supporting device, comprise housing, and comprise in the housing that UW cracks chamber, air flotation separating chamber and collecting chamber; The collecting chamber bottom is provided with sewage draining exit and rising pipe; Its special character is: be linked with many headers on the rising pipe in the said collecting chamber, the top of said hull outside is provided with effluent trough, this effluent trough and rising pipe UNICOM; Top, side at effluent trough is communicated with ash shoot, is communicated with slag notch on the ash shoot.

Compared with prior art, the utility model has the advantages that: the utility model is adjusted the frequency band and the amplitude of ultrasonic unit according to the characteristics of blue charcoal waste water, to guarantee its chain rupture effect, has strengthened frequency and amplitude.The employing multitube catchments, and has thoroughly solved the UW stack and has caused the problem that secondary cracks, and has also solved the low problem of treatment capacity, through setting out slag chute on the rising pipe, has solved the slag pollution problem simultaneously, and treatment effect is largely increased.

Description of reference numerals is following:

1-UW cracks the chamber, 2-air flotation separating chamber, 3-collecting chamber, 4-sewage draining exit, 5-header, 6-slag notch, 7-rising pipe, 8-ash shoot, 9-effluent trough.

Embodiment

Below in conjunction with accompanying drawing the utility model is done detailed description.

Referring to Fig. 1, a kind of UW air supporting device comprises housing, comprises in the housing that UW cracks chamber 1, air flotation separating chamber 2 and collecting chamber 3, and collecting chamber 3 bottoms are provided with sewage draining exit 4 and rising pipe 7.Be linked with many headers 5 on the rising pipe 7 in the said collecting chamber 3, the top of said hull outside is provided with effluent trough 9, and this effluent trough 9 and rising pipe 7 UNICOMs are communicated with ash shoot 8 on the top, side of effluent trough 9, are communicated with slag notch 6 on the ash shoot 8.

When using the utility model, sewage gets into UW through water inlet pipe and cracks chamber 1, and the sewage overflow of sewage after the UW effect crossed dividing plate; Get into air flotation separating chamber; The molten gas air water that dividing plate is crossed in overflow gets into collecting chamber 3, is discharged by sewage draining exit 4, and clear water gets into rising pipe 7 through compiling of header 5; Scum silica frost gets into ash shoot 8, is discharged by the residue outlet that is provided with in the ash shoot 86 then.
