The constant pressure control device comprises a high pressure pump, a membrane tube and a controller, wherein, the high pressure pump is connected with the inlet of the membrane tube through a delivery pipe; a pressure sensor is arranged at the outlet of the high pressure pump; the pressure sensor is electrically connected with the controller; and the controller is also connected with the frequency modulating circuit of the high pressure pump in series. The controller is a variable frequency controller, and is arranged in a control cabinet on one side of a membrane tube frame. When in use, industrial wastewater delivered by a delivery pump enters into the membrane tube through the high pressure pump for being separated by a membrane core in the membrane tube, and water from the membrane returns to the production line for use. The pressure sensor is arranged at the outlet of the high pressure pump, the frequency of the high pressure pump is adjusted through the change of the water flow detected by a frequency converter, and the water pressure output by the pump is enabled to maintain a certain value. The utility model has the advantages of simple and flexible operation, good membrane core cleaning effect, qualified recycle water quality, and the like.
Description
Technical field
The utility model discloses a kind of Industrial Wastewater Treatment film system constant voltage control device, belongs to Industrial Wastewater Treatment class manufacturing technology field.
Background technology
Trade effluent is meant waste water, sewage and the waste liquid that produces in the Industrial processes, wherein contains the pollutent that produces in the industrial production materials, intermediate product and the product that lose with current and the production process.Along with developing rapidly of industry, the kind and the quantity of waste water rapidly increase, and is also extensive day by day and serious to the pollution of water body, threatens human beings'health and safety.For the protection environment, the processing of trade effluent is more even more important than municipal sewage treatment.Though the processing of trade effluent began as far back as 19 end of the centurys, and great deal of experimental and production practice have been carried out in half a century subsequently, but because many trade effluent complicated components, character is changeable, still has some technical problems not solve fully so far.
Trade effluent can be divided into paper waste, textile printing and dyeing wastewater, leather-making waste water, electroplating wastewater etc. by the product and the processing object classification of industrial enterprise, because the composition difference in the various waste water, as contain the material of toxic and don't readily biodegradable, comprise heavy metal, toxic compounds and be difficult for by biodegradable organic compound etc., so handling the technology and the method for trade effluent will suit the remedy to the case, the waste water of heterogeneity is suitable for corresponding technology, reaches national emission standards requirement.Under the urgent day by day situation of water and the shortage day by day of other resources and environmental pollution improvement, the development trend of Industrial Wastewater Treatment is: water and pollutent are recycled and carry out closed cycle as useful resources.The film device separation method is one of common method of handling trade effluent at present, because the composition variation in the waste water, film core in the film device also is to take place to change along with the difference of waste water composition, when former water enters into film device, because the filtration of film core always has certain full closing, when the water yield caused hydraulic pressure to increase too greatly, the filtering former water of institute just can not reach standard, therefore, controlling the hydraulic pressure that enters into the former water of film device is to realize handling one of former water committed step up to standard.
Summary of the invention
At the deficiency of existing film device control water hydraulics, the utility model provides a kind of rational in infrastructure, easy to operate Industrial Wastewater Treatment film system constant voltage control device, when this device can make raw water flow change and make the hydraulic pressure that enters into the film system constant.
The utility model is achieved through the following technical solutions:
The utility model comprises high-pressure pump, film pipe and controller, high-pressure pump is connected to the admission port of film pipe by transfer lime, wherein, pipeline between described high-pressure pump and the film pipe is provided with a pressure transmitter, this pressure transmitter is electrically connected with controller, and this controller is serially connected in the FM circuit of high-pressure pump.
Described film pipe is to be combined into one by some single tubes to be fixed in the framework, is connected with nanofiltration or reverse-osmosis membrane element in the every single tube.
Described controller is a frequency-variable controller, is installed in the housing of film tube frame one side.
When the utility model used, trade effluent was carried by dehvery pump, successively through more medium filter, security personnel's strainer and high-pressure pump, enter in the film pipe, separate operating pressure 10-15kg by the film core in the film pipe, film produces water and returns the production line use, and concentrated solution is qualified discharge after treatment.The pressure of common film system changes with the variation of raw water flow, and after in the high-pressure pump exit pressure transmitter being housed, the frequency of high-pressure pump is regulated in the variation that detects discharge by frequency transformer, is certain value and make the hydraulic pressure of pump output.
The utlity model has following useful effect:
1, the utility model utilizes frequency transformer and the pressure transmitter acting in conjunction that is arranged on the high-pressure pump outlet, makes the hydraulic pressure of high-pressure pump output keep certain value;
2, it is rational in infrastructure that the utility model is controlled hydraulic pressure, and film system recoveries water quality is good owing to water pressure invariableness.
