[0020] The utility model uses a fan 3 to draw negative pressure, and the raw material sodium carbonate entering from the lower hopper 19 falls into the preparation tank 1. The sodium carbonate dust in the preparation tank 1 is sent to the absorption barrel 2 through the primary dust absorption pipeline 8. First, it is absorbed by the high-purity water in the absorption barrel 2 (the high-purity water is pre-supplemented into the absorption barrel 2 through the water replenishment pipeline 10), and then it is reversely contacted with the spray water sprayed by the spray device for secondary absorption. Finally, it is sent to the preparation tank 1 through the overflow pipeline 9, and the sodium carbonate solution prepared in the preparation tank 1 is sent out through the sodium carbonate solution outlet pipeline 20. It has a reasonable and compact structure, is easy to use, can completely eliminate on-site dust, effectively reduces the harm of the on-site environment, and avoids harm to the health of operators.

[0021] The above-mentioned sodium carbonate dust absorption device can be further optimized and / or improved according to actual needs:

[0022] Embodiment 2: It is different from Embodiment 1 in that: Figure 1 , 2As shown, the spray device includes a liquid distribution pan 11 and a liquid distribution nozzle 12. A liquid distribution cavity is provided in the liquid distribution pan 11. A liquid inlet that can be connected to the liquid distribution cavity is provided on the left side of the liquid distribution pan 11. A plurality of liquid outlets are provided on the lower side of the liquid distribution cavity. A liquid distribution nozzle 12 is fixedly installed on the lower side of the liquid distribution pan 11 corresponding to each liquid outlet. A spray line 5 is fixedly connected between the high-purity water inlet pipeline 4 and the liquid inlet of the liquid distribution pan. Through such an arrangement, the sodium carbonate dust in the absorption barrel 2 is reversely contacted with the spray water sprayed by the liquid distribution nozzle 12, thereby achieving dust reduction.

[0023] Embodiment 3: It differs from Embodiment 1 to Embodiment 2 in that: Figure 1 As shown, the outlet end of the primary dust absorption pipeline 8 extends into the absorption barrel 2, and a downwardly opening elbow 13 is fixedly installed at the outlet end of the primary dust absorption pipeline 8. Through such an arrangement, dust can be more easily absorbed by the high-purity water in the absorption barrel 2 first.

[0024] Embodiment 4: It differs from Embodiments 1 to 3 in that: Figure 1 As shown, it also includes a liquid level detector 14, a liquid level detector 14 is fixedly installed on the side of the preparation tank 1, a spray valve 15 is fixedly installed on the spray pipeline 5, and a water inlet valve 16 is fixedly installed on the high-purity water inlet pipeline 4 between the preparation tank 1 and the spray pipeline 5, and an interlock is set between the liquid level detector 14 and the water inlet valve 16. Through such a setting, when the liquid level detector 14 detects that the high-purity water in the preparation tank 1 reaches the set value, the interlock water inlet valve 16 is closed, so that the operation process is partially automatically controlled.

[0025] Embodiment 5: It differs from Embodiments 1 to 3 in that: Figure 1 As shown, the lower bin 19 is provided with a hand hole 17. Through such an arrangement, the operator cuts open the sodium carbonate ton bag at the hand hole 17 of the lower bin 19 to avoid dust harming the health of the operator.

[0026] According to the needs, the primary dust absorption pipeline 8, the first air discharge pipeline 6 and the second air discharge pipeline 7 are all corrugated hoses, which are easy to disassemble, replace and clean during use.

[0027] As required, the various pipelines and equipment of the sodium carbonate dust absorption device may also be provided with conventional valves, thermometers and pressure gauges known in the art according to production needs.

[0028] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.

[0029] The use process of the embodiment of the utility model is as follows: first, high-purity water is injected into the preparation tank 1 through the high-purity water inlet pipeline 4. When the liquid level detector 14 detects that the high-purity water in the preparation tank 1 reaches the set value, the interlock control water inlet valve 16 is closed. At the same time, a certain amount of high-purity water is pre-added into the absorption barrel 2 through the water supply pipeline 10;

[0030] Next, the sodium carbonate ton bag is delivered to the upper part of the lower bin 19 by a forklift, and the operator breaks the bottom of the sodium carbonate ton bag from the hand hole 17 of the lower bin 19, and the sodium carbonate powder falls into the preparation tank 1 by gravity. At this time, the fan 3 is turned on, and the spray valve 15 is opened. The sodium carbonate dust on the upper part of the preparation tank 1 is delivered to the lower part of the absorption barrel 2 by the primary dust absorption pipeline 8. Most of the dust is first absorbed by the high-purity water in the absorption barrel 2. The unabsorbed sodium carbonate dust contacts the spray water sprayed by the spray device on the upper part of the absorption barrel 2 in reverse, and is absorbed twice in the absorption barrel 2 to form a sodium carbonate aqueous solution, which falls into the bottom of the absorption barrel 2;

[0031] Finally, after the sodium carbonate aqueous solution in the absorption barrel 2 reaches a certain height, it flows into the preparation tank 1 through the overflow pipeline 9. After the sodium carbonate solution prepared in the preparation tank 1 reaches a certain concentration requirement after being tested, it is sent out through the sodium carbonate solution outlet pipeline 20.
