Stable chemical vapor stream generating device

Abstract

The invention relates to a stable chemical steam flow generating device. The problem that a temperature-controlled steam flow generating device is not suitable for reagents with active properties is effectively solved. According to the technical scheme, the device comprises a shell, a plurality of transverse plates which are arranged up and down at intervals and an inclined plate are arranged in the shell; the inclined plate is located at uppermost position, the middle chamber is divided into a plurality of evaporation chambers by the inclined plate and the transverse plates; a first verticalpipe capable of moving up and down penetrates through the lowest part of the inclined plate; a second through hole is formed in the side wall of the first vertical pipe; a second vertical pipe is arranged on each transverse plate in a penetrating manner; a third through hole and a fourth through hole higher than the third through hole are formed in the side wall of the second vertical pipe, the third through hole can be opened and closed, a reagent in the evaporation chamber can be quickly emptied by opening the third through hole, and the liquid level areas on the transverse plate and the inclined plate can be adjusted by adjusting the height of the second through hole and opening and closing the third through hole; the steam concentration is controlled by controlling the evaporation area, so that the condition of reagent decomposition or chemical property change caused by temperature change is avoided.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a device for generating stable chemical vapor flow. Background technique [0002] In some chemical experiments or adsorption experiments on porous materials, it is necessary to form a controllable, adjustable and stable vapor flow of chemical reagents or organic liquids; current vapor flow generators generally use the method of changing the temperature to adjust the vapor concentration. However, for some reagents with active chemical properties, temperature changes will cause their decomposition or chemical properties to change, so it is not suitable for the evaporation control of active reagents. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a stable chemical steam flow generator, which effectively solves the problem that the temperature-controlled steam flow generator is not suitabl...
