Cement-based material carbon dioxide self-compensation circulating maintenance device and method
The invention relates to a cement-based material carbon dioxide self-compensation circulating maintenance device and method.The device comprises a CO2 generation chamber for providing and self-compensating CO2, a limestone block body and a diluted hydrochloric acid solution are contained in the CO2 generation chamber, and the limestone block body and the diluted hydrochloric acid solution react to generate CO2; the CO2 curing chamber is used for carrying out carbonization curing on the cement-based material test block and comprises an air inlet and an air outlet through which CO2 flows in and out; and the CO2 circulator is connected with the CO2 generating chamber and the CO2 curing chamber and enables CO2 flowing out of the gas outlet to flow back to the gas inlet. Compared with the prior art, the CO2 circulating device produces CO2 gas circulating flow in the CO2 curing chamber, the conveying speed of the CO2 gas to the cement-based material test block is improved through the convection effect, so that the carbonization curing efficiency and the CO2 utilization efficiency are improved, CO2 is provided through the Kipp generator, CO2 self-compensation in the carbonization curing process is achieved, manual gas supply is not needed, and the carbon dioxide curing device is simple in structure, convenient to operate and low in cost. And the device is simple, can be quickly assembled, has excellent economic benefits and environmental benefits, and can be used for replacing conventional carbonization curing equipment to carry out carbonization curing on the cement-based material.
本发明涉及一种水泥基材料二氧化碳自补偿循环养护装置及方法，该装置包括：提供并自补偿CO2的CO2发生室，其包括装有石灰石块体和稀盐酸溶液的启普发生器，所述石灰石块体和稀盐酸溶液反应生成CO2；用于对水泥基材料试块进行碳化养护的CO2养护室，其包括供CO2流入和流出的进气口和出气口；CO2循环器，其连接所述CO2发生室和CO2养护室，并使出气口中流出的CO2回流至进气口。与现有技术相比，本发明通过CO2循环器在CO2养护室内部制造CO2气体循环流动，通过对流效应提高CO2气体向水泥基材料试块传输的速度，从而提高碳化养护的效率及CO2的利用效率，通过启普发生器提供CO2并实现碳化养护过程中CO2的自补偿，不需要手动补气，也不需要额外配备CO2气瓶，装置简单可快速组装，具有优异的经济效益和环境效益，可替代常规碳化养护设备进行水泥基材料的碳化养护。
