Description

Technical Field

[0001] The utility model relates to a waste gas treatment device, in particular to an intelligent integrated device for synthesizing a polycarboxylic acid water reducer and treating waste gas. Background Art

[0002] Compared with traditional water reducers, polycarboxylate water reducers, as the third generation of water reducers, are widely used in the field of construction engineering due to their advantages such as low dosage, high water reduction rate, strong structural designability, high collapse resistance and large molecular structure freedom. Therefore, in recent years, polycarboxylate water reducers have become the preferred admixture for preparing high-strength, high-fluidity and high-durability concrete.

[0003] However, polycarboxylate superplasticizers (PCSs) produce organic gases such as nitrogen oxides during their synthesis, which not only pollutes the environment but also harms the health of researchers. Therefore, current PCSs require exhaust gas treatment equipment during both synthesis and experimental research. However, there are currently no exhaust gas treatment devices specifically designed for PCSs. Conventional exhaust gas treatment devices are used instead, which are complex, inconvenient, and poorly compatible with the PCSs formulation system, resulting in poor exhaust gas treatment effectiveness.

If necessary, the water collection drawer 26 can be reinforced with fasteners such as screws to avoid air leakage caused by opening it in the middle. It can be opened again when draining water.

[0043] In a preferred embodiment, the operating table 2 is provided with a peristaltic pump operating panel 21 , a heating and stirring switch 22 , a temperature adjustment knob 23 and a speed adjustment knob 24 .
