Description
Technical field
The utility model relates to a kind of Liqiud-gas mixing device, the self-suction low-pressure high-efficiency jet aeration device in particularly a kind of waste disposal plant.
Background technology
For city domestic sewage and industrial organic waste water mainly is to adopt aerobic biochemical to handle.Aerator is mainly blast aeration and mechanical aeration.Blast aeration is to become bubble to send in the water by the air dispersion that aerating apparatus is sent air blast here, and gas ducks in drink, and a part of oxygen dissolves in the water in the process that rises.When adopting biochemical method to carry out sewage disposal, aerating apparatus is the key equipment of sewage disposal, and the quality of sewage disposal, efficient and cost also depend primarily on aerating apparatus.Common aerating apparatus is because the trans-utilization rate of dynamic efficiency and oxygen is low, and the utilization ratio of oxygen is less than 15%, generally all between 6-13%.Fig. 2 is seen in use now jet aerator comparatively widely, in the housing (2) is negative pressure air cavity (5), the housing left port is sealedly connected with big, the inner little taper penstock (3) in outer end, right output port is sealedly connected with the air water mixing tapered tube (4) inner little, that the outer end is big, and housing (2) upper end is inlet pipe (1).Taper penstock (3) is separated by 3 millimeters with the inner face of air water mixing tapered tube (4).The trans-utilization rate of this device oxygen is up to 20-30%, but dynamic efficiency is low, operating pressure is higher, and total efficiency is low, and cost of sewage disposal is higher, is used for more small-sized sewage treatment project more.
Summary of the invention
The purpose of this utility model is to propose that the trans-utilization rate of a kind of dynamic efficiency and oxygen increases substantially, applicable to the self-suction low-pressure high-efficiency jet aeration device of large and medium-sized sewage treatment project.
Technical scheme of the present invention is, self-suction low-pressure high-efficiency jet aeration device, in housing (2) air cavity (5), the housing left port is sealedly connected with the pressure tapered tube (3) that the outer end is big, the inner end is little, right output port is sealedly connected with the air water mixing tapered tube (4) that the inner end is little, the outer end is big, housing (2) upper end is inlet pipe (1), it is characterized in that, it is running fit that the inner two pipe jointing places of air water mixing tapered tube (4) are inserted in the inner of pressure tapered tube (3), inserting length is the L=1-6 millimeter, gap H=3-7 millimeter.
When traditional jet aerator is worked, working fluid passes through the pressure tapered tube with certain pressure, overcome atmospheric drag at the inner port interval and contact with the air that is entered by inlet mouth and mix, atomize, working fluid is taken away gas, makes air cavity and air water composite cone shape pipe be in negative pressure state.The utility model has been broken through the principle of design and the structure of traditional jet aerator, and with inner air water mixing tapered tube the inner of directly inserting of pressure tapered tube, two pipe jointing places are running fit, and the size of inserting length and gap is to set according to the size of aerator.Air cavity only plays the effect of gas storage in the utility model, the working fluid of band pressure fully contacts in whole air water mixing tapered tube with air and mixes, atomizes, disperses, air in working fluid is taken away pipe, be in negative pressure state in the air water mixing tapered tube, air is mended air water mixing tapered tube automatically from two ligaments and is mixed continuously, atomizes, disperses with working fluid.The difference of the utility model and traditional jet aerator is, air water mixing route lengthening, the tradition jet aerator mainly is to realize that at two pipe intervals air water mixes, the utility model then is that air directly enters in the air water mixing tapered tube, thorough mixing in whole air water mixing tapered tube, because of air water mixing taper pipe volume less than air cavity, under identical operating pressure condition, the negative pressure that forms in the air water mixing tapered tube of the present utility model is obviously greater than the negative pressure in traditional air cavity, and inner small and outside big tapered tube is particularly conducive to the dispersion of air-water mixture.The utility model can make operating pressure by 2.5-3kg/cm
2Reduce to 1.5-2kg/cm
2, having improved nearly one times of dynamic efficiency, the trans-utilization rate of oxygen is brought up to 30-50 by 20-30%, has improved total efficiency, has reduced energy consumption.The utility model design is unique, design science is reasonable, serviceability is safe and reliable, making and easy to use, applicable to various types of sewage treatment projects,, greatly reduce cost of sewage disposal because total efficiency improves greatly, saved energy consumption, the utility model can be widely used in big-and-middle-sized sewage treatment project.
