Problems solved by technology

[0004] The air tent is mainly composed of a metal chassis, steel pipe frame and plastic film laid on the frame, etc. There are two partitions in the air tent, with its own ventilation system. The air tent and the wall of the hot room are sealed with tape. The main disadvantage is that Huge amount of preparation work and poor sealing
Although the skeleton can be reused, the plastic film cannot be reused and becomes radioactive waste. In addition, because the air tent itself is sealed with a plastic film, its strength is poor and it is easily damaged, resulting in poor sealing safety of the air tent

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1-3 As shown, the vertical butt joint type universal hot cell maintenance airlock provided by the present invention includes an airlock body and a double-cover airtight door system. The airlock body is the transition channel for maintenance personnel to prevent the gas from contaminating the maintenance area in the hot chamber during maintenance operations, and it is also a space for maintenance personnel to wear, degas and store gas clothing. It is a sealed chamber made of stainless and acid-resistant steel plates. There are two independent partitions of the internal temperature division zone 16 and the hot zone 7 (the number of divisions can also be increased according to the needs). There is an airlock sealed outer door 19, an airlock sealed inner door 18 is arranged between the temperature zone 16 and the hot zone 7, and th...

Abstract

The invention relates to the design field of a nuclear industry box, in particular to a vertical butt-type universal hot-chamber maintenance air brake, which comprises an air brake main body and a dual-cover sealing door system, wherein the air brake main body is divided into a plurality of independent subareas, and all subareas are connected with one another through an air-brake sealing door; and the bottom of one independent subarea of the air brake main body is provided with a dual-cover sealing upper door, a top plate of a hot-chamber shell is provided with a corresponding dual-cover sealing lower door, and the dual-cover sealing upper door and the dual-cover sealing lower door form the dual-cover sealing door system. Due to the adoption of the vertical butt-type universal hot-chamber maintenance air brake, rapidness in butt joint and separation of multiple hot chambers can be realized through one air brake, the connection surface of the air brake after being separated is free from being polluted; and meanwhile, the vertical butt-type universal hot-chamber maintenance air brake has the advantages of high strength, good sealing performance, convenience in transportation and the like.

Description

technical field [0001] The invention relates to the field of nuclear industry chamber design, in particular to a special chamber equipment required for personnel to enter a hot chamber for maintenance. Background technique [0002] With the development of my country's nuclear industry, nuclear engineering has higher and higher requirements for equipment safety, maintenance, replacement, and operation in radioactive environments. Especially in recent years, with the continuous improvement of people's awareness of environmental protection, people-oriented design requirements have been advocated by more users. For this reason, it is required to avoid personnel entering the polluted area for maintenance operations as much as possible. Therefore, in the process of hot cell design As many means of remote operation and maintenance as possible are adopted, and the design of the equipment considers as little maintenance as possible. Although the above measures are taken, it is still ...
