Embodiment 1

[0028] The present embodiment provides a method for treating sludge in a brine storage tank, comprising the following steps:

[0029] Step 1: Disconnect the waste water pipeline from the first water pump 3 of the first regeneration waste water storage tank 4 to the fresh water tank 2, and connect the disconnected waste water pipeline nozzle and the mud pump 18 of the brine storage tank 1 through the first pipeline 10 to connect. Preferably, when disconnecting the waste water pipeline from the first regenerated waste water storage tank 4 into the fresh water tank, lead the disconnected waste water pipeline mouth to the ground, and then connect the mud pump 18 to the disconnected waste water pipeline through the first pipeline 10 Connect the nozzle. Preferably, the first pipeline 10 may be a temporary rubber tube.

[0030] Step 2: Disconnect the waste water pipeline from the first water pump 3 of the first regeneration waste water storage tank 4 to the primary brine purificati...

Embodiment 2

[0038] like figure 1As shown, this embodiment provides a sludge treatment system for a brine storage tank, including a brine storage tank 1 , a first regenerated wastewater storage tank 4 and a primary brine slag tank 12 . The brine storage tank 1 is provided with a mud pump 18, and the outlet of the mud pump 18 is connected to the waste water pipeline nozzle disconnected from the first water pump 3 of the first regenerated waste water storage tank 4 to the fresh water tank 2 through the first pipeline 10. The first water pump 3 of the first regeneration wastewater storage tank 4 is connected to the first brine slag pool 12 through the second pipeline 11 to the waste water pipeline nozzle disconnected in the primary refined brine process; 10 and the second pipeline 11 to the brine storage tank sludge extraction pipeline of the primary brine slag tank 12 . Preferably, a plate-and-frame filter press or a centrifuge is provided in the primary brine slag pool. During processing, ...

Embodiment 3

[0044] This embodiment is described by taking a chlor-alkali enterprise as an example.

[0045] A chlor-alkali enterprise currently has four groups of nine salt wells connected horizontally, with a daily output of brine of 350m3. The first- and second-line caustic soda plants have two brine storage tanks with a diameter of 50m and a volume of 10793m 3 , mainly plays the role of storing brine and buffering production. Since the brine storage tank was completed and put into operation in 2004, it has not been dredged. However, with the extension of the operation time, the sediment entrained by the return brine continued to deposit, and the effective volume of the brine tank continued to decrease. Until 2018, the 2# brine The effective volume of the pond has dropped to 33%. In order to increase the effective volume of the brine pond, in April 2018, the company used excavators to clear about 1000m of sludge from the 2# brine pond. 3 However, the excavated salt mud is thin and dif...

Abstract

The invention provides a treatment method and a treatment system for sludge of a brine storage tank, and solves the technical problems that the sludge treatment method in the prior art is relatively high in investment cost and needs to be stopped for operation. The method comprises the following steps: disconnecting a wastewater pipeline from a first water pump of a first regenerated wastewater storage tank to a fresh water tank, and connecting a pipe orifice of the disconnected wastewater pipeline with a slurry pump of a brine storage tank through a first pipeline; disconnecting a wastewater pipeline from a first water pump of the first regenerated wastewater storage tank to a primary brine refining process, and connecting a pipe orifice of the disconnected wastewater pipeline to a primary brine slag tank through a second pipeline; therefore, a brine storage pool sludge extraction pipeline from the brine storage pool to the primary brine slag pool through the first pipeline and the second pipeline is formed. According to the method disclosed by the invention, the sludge in the brine storage tank intermittently flows back to the primary brine slag tank by utilizing the resin tower regeneration wastewater pipeline of the existing electrolysis device, so that the purpose of cleaning the sludge in the brine storage tank is achieved, only one-time investment is needed, and the repeated utilization rate is relatively high.

Description

technical field [0001] The invention relates to the technical field of dredging of brine storage tanks, in particular to a sludge treatment method and treatment system for brine storage tanks. Background technique [0002] In the process of refining and producing mine brine, chlor-alkali enterprises need to establish brine storage tanks for brine storage and buffer production. With the extension of the operation time, the sediment entrained by the return brine continues to deposit, and the effective volume of the brine pool continues to decrease. Once the vacancy of the brine pool decreases sharply, the salt well fails or the overhaul stops the salt well pressure relief and drainage. Production poses a threat. At present, for the brine storage tank of mine salt chlor-alkali enterprises, the mud re-injection method is generally used to clean the sludge in the brine storage tank, that is, the high-pressure plunger pump is used to dilute the salt sludge and inject it into the ...
