Tunnel purification system capable of automatically supplying hot water for cleaning and dehumidifying

Abstract

The tunnel purification system comprises a heat preservation water tank and a heat recovery and dehumidification mechanism, the heat recovery and dehumidification mechanism comprises a coil evaporator, a compressor and a shell and tube condenser which are connected through a pipeline, the coil evaporator is arranged between an activated carbon module and an electrostatic dust collection module, and the compressor is connected with the shell and tube condenser through a pipeline. The heat exchanger is used for absorbing heat in air passing through the periphery of the coil evaporator for dehumidification, the compressor is used for compressing a refrigerant into high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the shell-and-tube condenser for heating clean water flowing through the shell-and-tube condenser; the heat preservation water tank is connected with the shell and tube condenser, the water supplementing tank and the electrostatic dust collection module, and hot water heated by the shell and tube condenser is output to the electrostatic dust collection module to be cleaned. The cleaning effect is improved, and a dehumidification function is added, so that the humidity of air entering activated carbon is reduced, the service life of the activated carbon is prolonged, and the cost of a user is reduced.

Description

technical field [0001] The application belongs to the technical field of tunnel air purification, and in particular relates to a tunnel purification system with self-supplied hot water for cleaning and dehumidification. Background technique [0002] Electrostatic air purification systems are widely used in tunnel air purification, industrial waste gas dust removal, industrial oil fume purification and other places where air purification is required. Such purification systems generally include: primary filter, electrostatic dust removal board and activated carbon. Among them, the primary filter screen filters the larger particles in the air, and the air after the primary filter enters the electrostatic module for purification; the electrostatic precipitator is provided with a high-voltage ionization section and a low-voltage dust collection section, the high-voltage ionization section ionizes dirty air, and the low-voltage The dust collection section collects the fine particl...

Problems solved by technology

However, normal temperature water such as urban water supply is used for automatic cleaning. In order to achieve the purpose of cleaning, consumable auxiliary products such as cleaning agents are often added manually. , and because the dust particles collected from the air often contain oil, so when the cleaning agent and water supply are at normal temperature, once the temperature is low, the cleaning agent will be difficult to dissolve the oil, resulting in unclean cleaning; at the same time, in the cleaning process The water mist produced will increase the moisture content of the air, or in seasons with high humidity, if the moisture in the air is absorbed by the activated carbon, the life of the activated carbon will be greatly reduced
