A environment replacement ventilation control and purification protection system for burial pits in ruins museums

Abstract

The invention discloses a ruins museum burial pit environment replacement ventilation control and purification protection system. The system is composed of an air handling device, an air transfer pipeline, and displacement ventilation air supply and return ports. Returned air is purified by primary-efficiency and medium-efficiency filters. The temperature and humidity of air are regulated by a heat exchange coil, a steam humidifying nozzle and a reheater according to the temperature and humidity requirements of cultural relic preservation. The air after handling is transferred by a centrifugal variable-frequency fan to an area of cultural relics at low speed via an orifice air supply outlet arranged in the bottom of one side of a soil partition beam and then flows back to a combined air conditioner cabinet via an air return inlet arranged in the upper part of the soil partition beam of a burial pit, and thus, piston displacement air flow, namely, an air lake, is formed in the local area in the burial pit. Regulation of the temperature and humidity environment and purification of air in the local area of cultural relic preservation in a burial pit are realized, damage caused by environment fluctuation and pollution in the process of cultural relic preservation in a ruins museum is avoided, and long-time preservation of cultural relics unearthed from sites is realized.

Description

technical field [0001] The invention belongs to the field of regulation and purification of cultural relics protection and museum cultural relics preservation local environment, relates to the purification treatment and temperature and humidity regulation of circulating air supply, and particularly relates to a ventilation regulation and purification protection system for burial pit environment replacement in ruins museums. Background technique [0002] As a country with an ancient history and civilization, my country has discovered more than 400,000 historical sites. Most of the cultural relics and the natural environment in which the sites are located represent the relics of human historical activities. Therefore, when we discuss the protection of these cultural relics, we must consider Cultural relics cannot be separated from their natural environment. The methods of protecting the original site of cultural relics include excavation and backfill protection, establishment o...
