Improved dual-channel gas heating device

Abstract

The invention discloses an improved double-channel gas heating device, which includes a heating box, a heating device installed in the heating box, a blower fan and an air supply duct. There are two branches, one of which is a spiral pipeline, which enters the heating box from the right end and passes through the box from the left end. Firstly, the present invention can meet the requirements of ordinary heating devices for gas heating through straight-through pipelines; compared with straight-through pipelines, the spiral pipeline of the present invention has the characteristics of longer stroke, so compared with straight-through pipelines, under the same temperature heating conditions, the gas flow rate in the tank is increased. The stroke in the body can strengthen the heating function of the gas, and the passage of the gas can be selected through the switch of the valve body.

Description

technical field [0001] The invention relates to a gas temperature control device, in particular to an improved double-channel gas heating device. Background technique [0002] In the process of heating the gas, a heating box can be installed, and a gas pipeline can be set in the box. By feeding the gas into the pipeline, the heating box can heat the gas, so that the gas can be heated. Usually, one pipeline is designed in the box, and its The length directly affects the stroke of the gas and its heating effect. When heating the gas, we may need to achieve different heating degrees for the same gas under the same condition, but the above functions cannot be realized in the case of only one pipeline. [0003] Moreover, in some chemical experiments or research, some inert gases need to be preheated before heating to make their heating effect better. Usually we will set up a preheating box or preheater before heating, which is more troublesome to operate. Yes, and setting up the...

[0003] Moreover, in some chemical experiments or research, some inert gases need to be preheated before heating to make their heating effect better. Usually we will set up a preheating box or preheater before heating, which is more troublesome to operate. Yes, and setting up the preheater also increases the budget
