Description

Technical Field

[0001] The present invention relates to the field of environmental protection technology, and more specifically to the field of a freely configurable multi-stage reactor group and method technology. Background Art

[0002] In environmental protection projects, we often encounter situations where multiple treatments of the same type of reactor are required. For example, in the field of wastewater treatment, multi-stage AO biochemical treatment, multi-stage sand filtration, and multi-stage ion exchange are often used to complete wastewater treatment with specific requirements; in the field of waste gas treatment, multi-stage scrubbers and multi-stage adsorption towers are also often used to complete waste gas treatment with specific requirements. During the adjustment of the operating conditions of the reactor or the maintenance of the equipment, there are situations where the number of operating stages or the sequence is required to be adjusted. For example, in a three-stage ion exchange resin reactor, the sequence is represented by ABC. Each stage has two operating ion exchange resin tanks and one standby ion exchange resin tank. The functions of the resins filled in each stage are different. Due to the large fluctuation of the influent, ABC operation is sometimes required, and BCA operation is sometimes required according to different working conditions. For example, in a three-stage waste gas treatment reactor, each stage is acid washing, alkaline washing, and adsorption. Due to the differences in the working conditions of the waste gas, the waste gas components are different. Sometimes "acid washing-alkaline washing-adsorption" operation is required, and sometimes "adsorption-acid washing-alkaline washing" operation is required.

[0003] In the existing processing methods, most of them are adjusted by the operation and maintenance technicians by changing the pipeline access method to adjust the operation level or the order of the levels. This method is only suitable for the case where the frequency of operation condition adjustment or equipment maintenance is low. If the frequency is high, this processing method is complicated to operate, the adjustment speed is slow and it is easy to make mistakes.

[0004] In order to improve the adaptability of a multi-stage reactor to complex working conditions and to solve the problem of flexibly configuring the operating stages and the sequence of stages in a multi-stage reactor, the present invention proposes a method for flexibly configuring the operating stages and the sequence of stages in a multi-stage reactor by adjusting valves. Summary of the invention

It is only necessary to open the secondary water inlet valve and the secondary water production valve, and close other valves at the same time. For the reactor, water can be obtained from the secondary water inlet main pipe to the main water inlet. After being processed by the reactor, the water is then processed from the main water production port, through the secondary water production valve, and then flows to the third-level water inlet main pipe.

A method for freely configurable multi-stage reactors according to claim 8, characterized in that: The steps include: In a multi-stage reactor system composed of a plurality of reactor units, the total water inlet (9) and the total water outlet (11) of each reactor unit are configured with a plurality of branch water inlets and a plurality of branch water outlets of the same number of stages, each branch water inlet is provided with a water inlet valve, and each branch water outlet is provided with a water outlet valve; The branch water inlets of the corresponding stages of each reactor unit are connected by the corresponding stage water inlet main pipes, and the branch water production inlets of the corresponding stages of each reactor unit are connected by the corresponding stage water production main pipes, and the water production main pipes of each stage are connected to the water inlet main pipe of the next stage; Through the control of the water inlet valve and the water production valve, the reactor unit can be placed in any allowed stage. Since any reactor unit in the entire multi-stage reactor system can be set independently without affecting each other, the operating stages and stage sequence of the multi-stage reactor units can be flexibly configured.
