Embodiment approach

[0022] As an embodiment of the present invention, the stirring plate 20 includes a limit block, a one-way valve and a propeller 201; the stirring plate 20 is evenly provided with small holes, the number of which is not less than six, and one end of the small hole A one-way valve is provided, the other end of the small hole is provided with a limit block, and the inlet ends of the small holes are alternately distributed on both sides of the stirring plate 20; the propeller 201 is placed in the small hole. When working, the reactant enters the small hole from the end where the one-way valve is installed, and the reactant flows out of the small hole from the end with the limit block; when the stirring plate 20 rotates, it is close to the one-way valve on the side of the No. Concentrated sulfuric acid is fed in, and the concentrated sulfuric acid flows to the side of the hydrochloric acid; when the stirring plate 20 rotates, it is close to the check valve on the side of the No. A ...

Abstract

The invention belongs to the technical field of chemical equipment, and specifically relates to an automatic compensating hydrogen chloride generator. Hydrogen chloride gas generated in a reaction box enters a gas collection chamber to increase the hydrogen chloride gas in the gas collection chamber. When the pressure in the gas collection chamber is greater than the pressure in the reaction box , the pressure of the gas collection chamber pushes the No. 2 sliding plate to slide downward, the No. 2 sliding plate pushes the stirring plate and the No. 1 sliding plate to slide downward, the gas between the No. Enter the compensation unit, when the gas pressure of the compensation unit rises to a certain value, the gas breaks through the pressure valve and enters the upper part of the compensation unit, the No. 3 sliding plate slides upward, and the gas above the No. 3 sliding plate is squeezed into the No. The feed port blows the reactants in the feed port to make the reactants enter the reaction box more quickly. This process can accelerate the input speed of the reactants with the consumption of hydrochloric acid and the increase of hydrogen chloride gas.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, in particular to an automatic compensating hydrogen chloride generator. Background technique [0002] As we all know, HCl and H 2 The dilute hydrochloric acid formed by O has a high-boiling azeotrope, that is, its boiling point is higher than that of pure H 2 For O and HCl, the azeotropic point and azeotropic composition vary with pressure. Therefore, to treat dilute hydrochloric acid to make HCl and H 2 O separation, with simple distillation or stripping method is not acceptable. At present, there are the following two methods for the full analysis of industrialized dilute hydrochloric acid: (1) calcium chloride method: CaCl 2 Aqueous solution extraction breaks the azeotrope to recover HCl, that is, adding calcium chloride to dilute hydrochloric acid breaks the limit of its azeotropic point and separates hydrogen chloride; however, there are many problems in the calcium chloride m...
