Description
Technical field
The present invention relates to a kind of chemical lab water saving device that combines laboratory ventilation mechanism, belong to that E03B catchments, the water distribution field.
Background technology
In the elementary teaching laboratory that is used for basic professional skill training of each chemistry department of colleges and universities; Many relate to distillation or reflux operations are arranged in the chemical experiment of throughout the year arranging; When tens of names even hundreds of students launch this type experiment simultaneously; The cooling water discharge port separately that can see several covering devices or even tens of covering devices is directly to drain, and the tap that is equivalent to several or even dozens of is being opened directly simultaneously and discharged water to sewer, and these cooling waters are directly to draw from running water; Just so in device, flow to turn around and enter sewer immediately; Pay close attention to this phenomenon, will recognize how serious it is that the water resource waste that causes thus has, above-mentioned water resource waste situation and be the high throughout the year one of the main reasons of chemistry department of each colleges and universities water rate spending.
Summary of the invention
Technical problem to be solved by this invention is, to the water resource waste problem that exists in each above-mentioned chemistry department of colleges and universities elementary teaching experimentation, researches and develops a kind of water saving fixtures of addressing this problem of helping.
The present invention solve the technical problem through following scheme, and this scheme provides a kind of chemical lab water saving device that combines laboratory ventilation mechanism, and these water saving fixtures comprise sparge pipe; And, collector pipe, and; Counterflow cooling tower, and, water pump; The water inlet interface UNICOM of the water outlet interface of counterflow cooling tower and water pump, the water outlet interface of water pump and sparge pipe UNICOM, the water inlet interface of counterflow cooling tower and collector pipe UNICOM; Said collector pipe and sparge pipe are tube, on collector pipe and sparge pipe, all are equiped with many taps, and; Ventilating kitchen, this ventilating kitchen are the ventilating kitchens that chemical laboratory uses, an end UNICOM of this ventilating kitchen and ventilating kitchen exhaust duct; The air inlet UNICOM of the other end of ventilating kitchen exhaust duct and ventilating kitchen exhaust blower, the sidewall of this ventilating kitchen is equiped with collateral branch's air interface, and this collateral branch's air interface is via the exhaust outlet UNICOM of pipeline and counterflow cooling tower.
Its art-recognized meanings of counterflow cooling tower one speech is known; Counterflow cooling tower market is on sale.
The ventilating kitchen that said chemical laboratory uses, as far as chemical industry staff and relevant speciality cabinet producer, its art-recognized meanings is known.
Side towards the user of ventilating kitchen offer usually can folding windowpane, when said windowpane is shut fully, just become unique air air flue that flows with the air flue of counterflow cooling tower UNICOM.
This case device combines to have utilized ventilating kitchen air channel and ventilating kitchen exhaust blower power, makes said counterflow cooling tower can be placed in inside, laboratory, and needn't be placed in the outdoor of inconvenience supervision.
Said sparge pipe is the pipeline that is used for distributing to each side-by-side reactions device cooling water, and said collector pipe is to be used to collect the waste water that receives thermal pollution that the temperature of flowing through after each side-by-side reactions device rises to some extent.It is said that to receive its pollution factor of waste water of thermal pollution only be temperature rise.These water saving fixtures can further include the filter that can be installed in any position in the circulation line; This filter can be used for the impurity in the filtering pipeline water; Cycling use of water can access under the situation of periodic replacement in water saving fixtures, and said filter is optional.These water saving fixtures certainly comprise the water compensation mechanism that is used for to the bottom water tank moisturizing of said counterflow cooling tower, and its art-recognized meanings of said water compensation mechanism itself is known, and said water compensation mechanism is optional, because also manually moisturizing.
The installing and locating position separately of said collector pipe and sparge pipe be can be as required random installing and locating; But; For the ease of taking and the collection and the Recycling of thermal pollution waste water of cooling water, preferably installing mode is that said collector pipe and said sparge pipe are parallel to each other.
Based on the cause of this case, the structure of said water saving fixtures can comprise experimental bench, and said experimental bench is platform shape thing or table shape thing, and said collector pipe and sparge pipe are installed in said experimental bench.Under this situation, said collector pipe and sparge pipe can be erected on the table top of experimental bench, perhaps, are erected on the table top peripheral position of experimental bench, also can be erected on the lateral location of experimental bench.Said collector pipe and sparge pipe both can laterally set up with the experimental bench table top abreast, also can set up with the orthogonal direction of experimental bench table top.
Many speech in the scheme mean more quantity, and said many for example six, eight, ten, 20,30,40,50,60, or the like.
Further preferred construction comprises shutter, and the installation position of said shutter is the locations of structures at said collateral branch air interface, and said shutter is the shutter of automatically controlled folding.The existence of the shutter of said automatically controlled folding can be isolated different gas channels where necessary.Its art-recognized meanings of the shutter of said automatically controlled folding is known; The shutter market of said automatically controlled folding is on sale.
Advantage of the present invention is; Break through in chemistry department of each colleges and universities elementary teaching laboratory the ubiquitous running water that directly utilizes and made cooling water; And behind the device of once flowing through just discarded usual thinking and practice, this case links together counterflow cooling tower and installation position at experimental bench table top or near the sparge pipe it and collector pipe, form a kind of effective water saving fixtures; This case device reaches the Recycling purpose through collecting the thermal pollution waste water and the processing of lowering the temperature.This case device helps to solve described water resource waste problem.
