Description
Technical field
The utility model belongs to a kind of environmental protection technology, specifically a kind of device testing aerator oxygenation capacity, for accurately controlling aeration rate, and test result accurate and effective.
Background technology
Aeration is the important technological process of in sewage aerobic biological treatment system.The effect of aerator is that air dispersion is become bubble, be diffused in mixed liquor, the oxygen in bubble is made to be dissolved in mixed liquor, dissolved oxygen DO required for microbial biochemical reaction is provided, ensure the abundant mixing of sewage simultaneously, make active sludge be in suspended state, by the abundant contact of mud, water, gas three-phase, ensure that active sludge makes full use of oxygen in water and comes decomposing organic pollutant and nitrogen, phosphorus nutrition thing.The quality of aeration effect greatly affects the efficiency of biological treatment system, and the material of aerator and structure directly affect aeration effect, therefore just particularly important to the test evaluation of aerator oxygenation capacity.Existing comparatively ripe aerator oxygenation capacity detection means now, but it is simple to there is device in it, can not adapt to multiple aerator demand, the problems such as aeration precision is not high, and general only adaptation in aeration tank with clear water is medium, can not adapt to medium is contain the such situation of Packed sewage.For above-mentioned situation, need to develop the more perfect the performance of aeration device proving installation of a kind of structure, more desirably to meet the demand that people test aerator.
The content of utility model
The purpose of this utility model is to solve the problems of the technologies described above, a kind of the performance of aeration device proving installation is proposed, this device is by the effect of automatic flow control valve, in conjunction with the design of air accumulator, the precision measurement of aeration rate can be realized on industrial computer, easy and simple to handle, Be very effective, result accurately and reliably, and can adapt to the demand of different aerator, and can test under Packed wastewater media.
The purpose of this utility model is achieved through the following technical solutions:
The performance of aeration device proving installation, is characterized in that: be provided with a test pools, is provided with two cover aerating pipelines in this basin bottom, settles aerator by actual test target; Be provided with an air compressor machine and an air accumulator in test pools side, described air engine is the automatic control air compressor machine keeping constant pressure in tank; Described two cover aerating pipelines are equipped with high-precision self-controlling flow variable valve, thermal air flowmeter and temperature sensor respectively; Be provided with one at the opposite side in pond and make the well-mixed self-controlled circulating water pump of liquid; And before water circulating pump, install a filtrator additional, block ebullator to prevent filler: be separately provided with a molten medicine explosive box, this explosive box is provided with automatic control dosing pump and is connected with test pools with chemical feed pipe, and described chemical feed pipe is deep into bottom test pools; Evenly place three groups of dissolved oxygen DO test probes from top to bottom in the underwater of test pools, this probe connects online dissolved oxygen DO hyperchannel transmitter and dissolved oxygen sensor; The PLC industrial computer of the above automatic control air compressor machine, self-controlling flow variable valve, air flowmeter, temperature sensor, self-controlled circulating water pump, automatic control dosing pump, line dissolved oxygen DO hyperchannel transmitter and dissolved oxygen sensor and setting carries out signal and control linkage.
Know-why: this device adds appropriate deoxidizer anhydrous sodium sulfite by dosing pump, and catalyzer cobalt chloride, after the circulation of water circulating pump, first by the dissolved oxygen approach exhaustion in clear water in test pools or sewage, namely dissolved oxygen amount reaches 0mg/L, opens air compressor machine subsequently, and air is delivered in water through aerator, realize the object of oxygenation, the dissolved oxygen in water constantly rises; When the dissolved oxygen value in water reaches the saturation values of dissolved oxygen of Current Temperatures, stop aeration, according to dissolved oxygen DO relation over time, a series of energy indexs of aerator used can be calculated.
The performance of aeration device proving installation of the present utility model compared with prior art, achieves by industrial computer to whole implementation Process operation and monitoring, and does not need manual operation.Meanwhile, by fundamental error be ± 2.5% automatic flow control valve and flow accuracy be the adjustment of the thermal air flowmeter of ± 1%, achieve the precise hard_drawn tuhes to aeration; By arranging head tank, ensure the stable of aeration tolerance; By designing two groups of pipelines, the demand of multiple aerator can be adapted to; By settling dissolved oxygen probe at underwater different depth, three groups of test results finally can be drawn, to ensure that result accurately and reliably.The utility model has structure improvement, and control flexibly, test is accurate, automaticity high plurality of advantages.
