Water saving device in chemical laboratory combined with laboratory existing ventilating structure

Abstract

The invention relates to a water saving device in a chemical laboratory combined with a laboratory existing ventilating structure, which belongs to the field of water collecting and water distributing. In the present correlation background art, the problems that the deficient strain capability of power consumption of the water saving apparatus and inter system circulating water pollution caused by chemical reaction solution splash are existed. The above problems are solved by the invention. Under the background that a linkage heat radiation mechanism of an original cross-flow type cooling tower and a ventilation cabinet is directly connected with a water utilization mechanism, a structure mode can be changed by the device, a waterstorage tectonic body with heat storage buffer effect is added between two mechanisms, the original continuous and unintermittent operation of a heat radiation mechanism can be changed to an intermittent operation though a heat exchange mechanism and a timely motion of an automatic temperature control switch, therefore the purpose of water saving without wasting electric power resource can be achieved; simultaneously, an opening position of the lateral air interface is moved on an exhaust pipe of a fume cupboard far away from a chemical experiment operating console, thereby the splash influence can be eliminated.

Description

technical field [0001] The invention relates to a chemical laboratory water-saving device combined with the existing ventilation structure of the laboratory, which belongs to the field of water collection and distribution of E03B. Background technique [0002] In the basic teaching laboratories used for basic professional skills training in the chemistry departments of various universities, many of the chemical experiments arranged all year round involve distillation or heating and reflux operations. When dozens or even hundreds of students carry out such experiments at the same time , it can be seen that the cooling water outlets of several sets of devices or even dozens of sets of devices directly lead to the sewer, which is equivalent to several or even dozens of faucets that are open at the same time and directly discharge water to the sewer. It is drawn from tap water, just circulates in the device and then discharged into the sewer. If you pay attention to this phenome...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to solve the problem of insufficient power consumption and strain capacity of the cooling tower plus ventilation hood linkage system existing in the above-mentioned solution of application number 200910159725.4, and the problem of the influence of the splash of the chemical reaction liquid. A water-saving device that not only pays attention to water saving, but also takes into account the power consumption saving of the cooling tower plus ventilation hood linkage system, and at the same time can eliminate the impact of the splash of the chemical reaction liquid
