The application discloses an application of a beta-cyclodextrin polymer and a grey water scale inhibition dispersant compound, and the compound comprises the following components and has the following weight ratio in terms of solid content: 50-90% of the beta-cyclodextrin polymer, 0-50% of hydrolyzed polymaleic anhydride, 0-50% of polyepoxysuccinic acid sodium and 0-50% of polyaspartic acid. The application is used for coal gasification grey water scale inhibition dispersant, and the mechanism is that the beta-cyclodextrin polymer performs grey water scale inhibition through inclusion, chelation and lattice inhibition of metal ions. The grey water scale inhibition dispersant compound of the application contains the beta-cyclodextrin polymer, and the beta-cyclodextrin polymer is used in combination with the hydrolyzed polymaleic anhydride, the polyepoxysuccinic acid sodium or the polyaspartic acid. Since the combined materials are all amphiphilic molecules with hydrophilic parts and hydrophobic parts, a variety of supramolecular aggregation systems, namely a self-assembly system of the "supramolecular cyclodextrin amphiphilic molecule", are formed, and the beta-cyclodextrin polymer can better play the scale inhibition role.

This invention relates to a device and method for the self-coupling utilization of high-temperature wastewater and hot water from alcoholysis waste liquid. The device includes: a methanol purification tower, a catalytic decomposition tower, a flash tank, a first reboiler, a methyl acetate purification tower, a cooler, and a centrifugal pump. The bottom of the methanol purification tower is connected sequentially to the flash tank, the first reboiler, and the catalytic decomposition tower via pipelines. The catalytic decomposition tower is connected to the methanol purification tower via the methyl acetate purification tower. The flash tank is connected sequentially to the centrifugal pump, the cooler, and the methyl acetate purification tower via pipelines. The high-temperature wastewater from the bottom of the methanol purification tower enters the flash tank, forming flash vapor and flash tank drainage. The flash vapor exchanges heat with the material in the catalytic decomposition tower in the first reboiler, cooling it to form hot water. The hot water and flash tank drainage are combined, cooled by the cooler to obtain cooling water, which then enters the methyl acetate purification tower. This self-coupling achieves the upgrading of high-temperature wastewater, waste heat recovery, wastewater reuse, and energy saving.
