Embodiment 1

[0038] Example 1: When using Taishan salinized salt mud as a raw material to carry out salt mud washing and fractionation, the initial components of the salt mud after testing are as follows: H 2 O 29.77%; Ca 2+ 15.64%; Mg 2+ 3.17%; SO 4 2- 23.74%; Cl - 4.91%; CO 3 2- 4.45%.

[0039] Converted to compound: H 2 O 29.77%; NaCl 8.09%; CaSO 4 2H 2 O 41.86%; CaCO 3 7.42%; Ca(OH) 2 5.41%; Mg(OH) 2 7.57%.

[0040] When 200-mesh and 400-mesh screens are used in the mud washing tank 2, only the mesh number of the screen is changed, and when the others remain unchanged, the component content after fractionation is as follows:

[0041] When using a 200 mesh sieve, the components of the sieve (dry basis) are as follows: CaSO 4 1 / 2H 2 O 72.19%; CaCO 3 20.43%; Ca(OH) 2 3.09%; Mg(OH) 2 4.23%.

[0042] When using a 400 mesh sieve, the components of the sieve (dry basis) are as follows: CaSO 4 1 / 2H 2 O 65.92%; CaCO 3 : 22.85%; Ca(OH) 2 : 6.79%; Mg(OH) 2 : 4.63%. ...

Embodiment 2

[0044] Example 2: The Taishan salinization salt mud in Example 1 was used as a raw material to carry out the salt mud washing and fractionation test, and the results are as follows.

[0045] When 100-mesh and 450-mesh screens are used in the mud washing tank 2, only the mesh number of the screen is changed, and when the others remain unchanged, the component content after fractionation is as follows:

[0046] When the primary sieve uses a 100-mesh sieve, the components of the sieve (dry basis) are as follows: CaSO 4 1 / 2H 2 O 76.76%; CaCO 3 18.89%; Ca(OH) 2 1.18%; Mg(OH) 2 2.93%;

[0047] When using a secondary sieve with a 450 mesh sieve, the components of the sieve (dry basis) are as follows: CaSO 4 1 / 2H 2 O 67.05%; CaCO 3 21.81%; Ca(OH) 2 6.53%; Mg(OH) 2 4.6%;

[0048] In this example, the semi-dry desulfurizer (dry basis) obtained after the 450-mesh sieve slurry sedimentation treatment is as follows: CaSO 4 2H 2 O 39.78%; CaCO 3 : 23.26%; Ca(OH) 2 : 4.92%;...

Embodiment 3

[0049] Example 3: The Taishan salinization salt mud in Example 1 was used as the raw material to carry out the salt mud washing and fractionation test, and the results are as follows.

[0050] When 80-mesh and 325-mesh screens are used in the mud washing tank 2, only the mesh number of the screen is changed, and when the others remain unchanged, the component content after fractionation and separation:

[0051] When the primary sieve uses a 80-mesh sieve, the oversize components (dry basis) are as follows: CaSO 4 2H 2 O 86.57%; CaCO 3 6.14%; Ca(OH) 2 4.32%; Mg(OH) 2 0.82%;

[0052] When using a secondary sieve with a 325 mesh sieve, the components of the sieve (dry basis) are as follows: CaSO 4 1 / 2H 2 O7 1.79%; CaCO 3 14.60%; Ca(OH) 2 9.24%; Mg(OH) 2 4.62%;

[0053] In this example, the semi-dry desulfurizer (dry basis) obtained after the 325-mesh sieve slurry sedimentation treatment is as follows: CaSO 4 2H 2 O 53.24%; CaCO 3 : 15.76%; Ca(OH) 2 : 3.99%; Mg(OH)...

Abstract

The invention discloses a salty mud treatment device, and particularly relates to an automatic grading treatment application device for high-content calcium sulfate salty mud. The device comprises a pulping tank, wherein the upper part of the pulping tank is provided with a feed port and is further provided with a water inlet, the water inlet is connected with an outlet of a water washing tank through a pipeline, a pipeline is connected to a liquid outlet in the upper portion of the pulping tank, a liquid outlet in the lower portion of the pulping tank is connected to an inlet of a first pulping pump through a pipeline, and an outlet of the first pulping pump is connected to a salty mud inlet of a mud washing tank through a pipeline. The device can be used for treating the high calcium sulfate salty mud conveniently and efficiently, is beneficial to environmental protection and creates more social value.

Description

technical field [0001] The invention relates to the environmental protection technical field of waste recycling, in particular to an automatic classification treatment application device for high-content calcium sulfate mud. Background technique [0002] A large amount of mineral salt is used in salt-making systems such as industrial salt or edible salt and salt industries such as chlor-alkali, and its main component sodium chloride can be utilized, but the large amount of salt mud that is accompanied by it has not been well utilized, mainly by stacking or The backfilling of salt wells not only wastes resources, but also causes land occupation and pollutes groundwater sources, which is not good for environmental protection. [0003] Due to the different components of sea salt or mineral salt in various places, in the salt industry such as industrial salt and edible salt or the salt industry for chlor-alkali and soda ash, the components of salt mud in different places are dif...
