Embodiment 1

[0030] As shown in the figure, this embodiment provides a device for preparing soda ash and ammonium sulfate from sodium sulfate, including a reaction kettle 1, a temperature control box 2, a stirring tank 3, and an extraction mechanism 4 for transferring intermediate liquids. The kettle 1 is installed above the stirring tank 3 through the support legs 5, the four corners of the support legs 5 are welded on the edge of the stirring tank 3, the temperature control box 2 is fixed on the support legs 5, and the extraction mechanism 4 is connected with the reaction kettle respectively. 1 communicates with the temperature control box 2. The inside of the reaction kettle 1 is a ceramic lining.

[0031] The working principle of this embodiment is as follows: using sodium sulfate to prepare soda ash and ammonium sulfate requires constant temperature regulation and stirring, the existing equipment cannot be well adapted, the operation is cumbersome, and the matching degree is not high....

Embodiment 2

[0033] This embodiment has been optimized as follows on the basis of Embodiment 1: the extraction mechanism 4 of this embodiment includes an anti-corrosion pipeline 41, a water suction pump 42, a telescopic tube 43, a water suction cover 44, and a floating ball 45, and the anti-corrosion pipeline 41 respectively connected with the upper end of the reaction kettle 1 and the upper end of the temperature control box 2; The ball 45 communicates with the telescopic tube 43 .

[0034] The working principle of this embodiment is as follows: During the preparation process, heavy metals need to be precipitated in the reactor 1 first, and then the liquid is transferred to the temperature control box 2. When the liquid is transferred, it is easy to bring the precipitated heavy metals together, affecting The quality of the finished product, in response to this problem, this device uses a float 45, a water-absorbing cover 44 and a telescopic tube 43, the float 45 floats up and down followi...

Embodiment 3

[0036] The present embodiment has been optimized as follows on the basis of Embodiment 1: the reaction kettle 1 of the present embodiment also includes a feed port 11, a slag discharge port 12, a pH meter 13, a temperature controller 14, and the feed port 11 Located at the top of the reactor 1, the slag outlet 12 is opened on the lower side wall of the reactor 1, the pH meter 13 is installed at the bottom of the reactor 1, and the temperature controller 14 is fixed on the shell of the reactor 1 superior.

[0037]The working principle of this embodiment is as follows: Since the pH value of the mixed solution needs to be controlled at any time during the reaction process, in order to realize the rapid measurement of the pH value, the device installs the pH meter 13 at the bottom of the reaction kettle 1 to read the solution in real time. The PH value improves the working efficiency of the device. The long-term accumulation of heavy metals in the reaction kettle 1 will easily af...

Abstract

The invention discloses a preparation device of sodium carbonate and ammonium sulfate by anhydrous sodium sulphate and a preparation method, and relates to the technical field of alkali preparation. The device comprises a reaction kettle (1), a temperature control box (2), a mixing tank (3), and an extracting mechanism (4) used for conveying middle fluid; the reaction kettle (1) is installed abovea bracket leg (5), and the temperature control box (2) is fixed on the bracket leg (5); the extracting mechanism (4) is connected with the reaction kettle (1) and the temperature control box (2). Themethod includes steps of step 1, raw material pretreatment; step 2, separation out of heavy metals; step 3, secondary adjustment of solution; step 4, replacement reaction; step 5, separation by crystallization. Through the device and the method, the temperature in reaction is more convenient to adjust and control; the preparation flow is more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of soda production, and more specifically relates to a device and a method for preparing soda ash and ammonium sulfate from sodium sulfate. Background technique [0002] Sodium sulfate, an inorganic compound, sodium sulfate decahydrate is also known as Glauber's salt, and the high-purity, fine-grained anhydrous substance is called Yuanmingfen. Yuanmingfen, white, odorless, bitter crystal or powder, hygroscopic. Appearance is colorless, transparent, large crystals or granular small crystals. It is mainly used in the production of sodium silicate, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye thinner, analytical chemical reagents, pharmaceuticals, etc. The traditional processing method uses the temperature changes in different seasons in nature to evaporate the water in the raw material liquid and crystallize the crude Glauber's salt. In summer, salty water containing sodium chloride...
