Embodiment 1

[0044] Such as figure 1 As shown, an automatic neutralization treatment test system for acidic radioactive waste liquid, including reaction tank 1, lye tank 2, electronic waste tank 3 and electric control mechanism, lye tank 2 is connected to the reaction tank through an alkali-resistant pump 4 1 is connected to the pipeline; the electronic waste liquid barrel 3 is connected to the pipeline of the reaction tank 1 through the acid-resistant pump 6; The module controls the liquid intake by controlling the speed of the alkali-resistant pump and the acid-resistant pump.

[0045] In this embodiment, in order to further accurately control the liquid intake, a lye flow meter 5 is set on the pipeline between the lye tank 2 and the reaction tank 1, and the flow meter 5 between the electronic waste tank 3 and the reaction tank 1 An acid flow meter 7 is arranged on the pipeline, and both the lye flow meter 5 and the acid flow meter 7 are electrically connected to the electric control mo...

Embodiment 2

[0060] Based on Embodiment 1, in this embodiment, in order to facilitate the installation of each device, the automatic neutralization treatment test system for treating acidic radioactive waste liquid also includes a mounting plate that provides installation positions for each device.

[0061] Further, in order to flexibly adjust the installation positions of each device, the installation boards are arranged in blocks for easy assembly, specifically: the installation boards include an alkali installation board 9 , an acid installation board 10 and a neutralization installation board 11 . The lye tank 2 and the alkali-resistant pump 4 are installed on the lye mounting plate 9; the electronic waste barrel 3 and the acid liquid flowmeter 7 are mounted on the acid liquid mounting plate 10; the reaction tank 1 and the electric control mechanism are installed on the neutralization installation plate 11. At the same time, in this embodiment, the connection of pipelines, alkali-resis...

Embodiment 3

[0065] Based on Example 1, for the reaction solution in the reaction tank 1 to react more fully, an auxiliary stirring device is set on the top cover 15 of the reaction tank 1, and the auxiliary stirring device has the same structure as the lye stirring mechanism. Stirring the reaction liquid in the reaction tank 1 by the auxiliary stirring device further enhances the easy disturbance, and cooperates with the neutralization stirring mechanism 14 to make the neutralization reaction more sufficient and improve the treatment efficiency of the acidic waste liquid.

[0066] Working process of the present invention is based on embodiment 3:

[0067] Assemble the device, measure the acid concentration through the pH meter in the electronic waste liquid barrel 3 and then calculate the demand for lye, open the movable plate 22, put the caustic soda into the lye tank that has been prepared with water, cover the movable Board 22, starting device.

[0068] The electric control module 8 c...

Abstract

The invention discloses an automatic neutralization treatment test system for treating acidic radioactive waste liquid, which comprises a reaction tank, a lye tank, an electronic waste liquid barrel and an electric control mechanism, the lye tank is communicated with a reaction tank pipeline through an alkali-resistant pump, and the pipeline is provided with a lye flow meter; the electronic waste liquid barrel is communicated with the reaction tank pipeline through an acid-resistant pump, and an acid liquid flow meter is arranged on the pipeline; the reaction tank and the lye tank are provided with stirring mechanisms, various parameter monitoring devices are arranged in the reaction tank, the lye tank and the electronic waste liquid barrel, the electric control mechanism comprises an electric control module, and the electric control module is in electric signal connection with the alkali-resistant pump, the acid-resistant pump, the stirring mechanisms and the various parameter monitoring devices, so that automatic control is realized. The acidic radioactive waste liquid is neutralized to be neutral, the situation that people make close contact with the waste liquid is reduced as much as possible in the process, and people are better protected.

Description

technical field [0001] The invention belongs to the technical field of waste liquid treatment, and in particular relates to an automatic neutralization treatment test system for treating acidic radioactive waste liquid. Background technique [0002] A large amount of acidic radioactive waste liquid will be produced when some scientific research work is carried out, mainly the nitric acid system with an acidity of 4mol / L~6mol / L, and some waste liquids are aqua regia system. The waste liquid can be discharged after further neutralization. The existing acid-base waste liquid neutralization collection device is manually operated to pour the acid or alkaline waste liquid into the neutralization tank, and then add the corresponding neutralization liquid for neutralization. Pour the neutralizing liquid into the acidic or alkaline waste liquid neutralization tank by manual operation, and a little carelessness may easily cause splashing, which will cause injury to the operator, and ...
