Chemical lab water saving device based on principle of evaporation and heat radiation

Abstract

The invention relates to a chemical lab water saving device based on the principle of evaporation and heat radiation, belonging to the field of water collection and distribution. The invention aims at solving the problem of cooling water waste during basic teaching experiments in chemistry institutes and departments of colleges and universities. The device comprises a water distribution pipe, a water collection pipe, a cross-flow cooling tower, a water pump, an exhaust duct and a ventilating fan; the water outlet of the cross-flow cooling tower is communicated with the water inlet of the water pump; the water outlet of the water pump is communicated with the water distribution pipe; the water inlet of the cross-flow cooling tower is communicated with the water collection pipe; both water collection pipe and the water distribution pipe are provided with a plurality of taps; and one end of the exhaust duct is communicated with the exhaust port of the cross-flow cooling tower, and the other end of the exhaust duct is communicated with the air inlet of the ventilating fan. The device is beneficial to solving the problem of water waste.

Description

technical field [0001] The invention relates to a chemical laboratory water-saving device based on the principle of evaporation and heat dissipation, 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 phenomenon, you...
