Problems solved by technology

[0003] The published literature and patents show that the current radon removal schemes mostly use enhanced ventilation, adsorption, chemical radon removal, etc., which have problems such as complex equipment, large floor area, and subsidiary pollutants, especially when the required land occupation is required. In a special environment with a small area, the existing radon removal device cannot meet its harsh use requirements, so a radon removal system is invented to meet different occasions and special use requirements

Embodiment Construction

[0008] The present invention will be further described below with reference to the accompanying drawings. As shown in the figure, there are two sets of adsorption regeneration devices 8(a) and 8(b) in the system, one for adsorbing radon gas and one for desorbing radon gas. In the following description of the embodiment, the adsorption regeneration device 8(a) is tentatively designated as a device that generates an adsorption process, and the adsorption regeneration device 8(b) is tentatively designated as a device that generates a desorption process.

[0009] The operation mode of adsorption and removal of radon is: the indoor radon-containing gas enters the drying box 2 to remove part of the water vapor in the radon-containing gas, and the radon-containing gas passes through the centrifuge 3 to become high-pressure gas; High pressure and low temperature gas; high pressure and low temperature radon-containing gas enters the adsorption regeneration device 8(a), radon gas is ads...

Abstract

A radon removal system is characterized in that the system is composed of an adsorption regeneration system, a radon gas collection system and a gas circulation treatment system, the system is controlled by a computer, data is collected by a sensor, implementation is carried out by an electric control valve, and a mechanical valve is used as an overhaul backup, so that automatic, safe and independent operation is realized; all the devices are manufactured in a modularized mode, all the assemblies are connected through flanges, assembling is convenient, damaged parts are easy to replace, accessory pollutants are not generated, full-automatic operation is achieved, safety and reliability are achieved, and management and maintenance are convenient.

Description

technical field [0001] The invention relates to a device for removing harmful gas, belonging to the invention in the technical field of gas cleaning. Background technique [0002] Radon is the decay product of the radioactive element radium. It is colorless, odorless and tasteless. It often exists in the air as radon gas in the form of elemental substance. It has stable chemical properties and all isotopes of radon gas are radioactive. Once radon is inhaled into the human body, it will accumulate in the lungs of the human body. The alpha particles generated by the decay of radon continue to cause radiation damage to the respiratory system, thereby causing lung cancer. Radon is currently the second leading cause of lung cancer. Radon gas in residential buildings comes from building materials, rocks and soil. Radon gas in soil only affects the basement and the first to third floors of the building. There are underground buildings, tunnels, laboratories, etc. where the indoor ...
