Front-end refrigerating and regenerated gas recycling and heating system for adsorbing drying machine

Abstract

The invention discloses a front-end refrigerating and regenerated gas recycling and heating system for an adsorbing drying machine, comprising a lower gas passage, a recycling gas passage, a coolant circulating module, an electric control part and a pneumatic control part, as well as an intake cavity and an exhaust cavity arranged in the lower gas passage, a barrel arranged on the lower gas passage, an upper gas passage communicated with the barrel, an exhaust cavity arranged in the upper gas passage, and an exhaust passage and a regenerated gas passage arranged in the exhaust cavity; the lower gas passage is communicated with the intake cavity or the exhaust cavity through a first one-way valve, and the upper gas passage is communicated with the exhaust cavity through a second one-way valve; the recycling gas passage is provided with a collecting and dehumidifying component, an intake passage and a recycling refrigerating component successively, and the regenerated gas passage is provided with a regenerating heating part; the coolant circulating module is integrated and dehumidifies the collecting and dehumidifying component, refrigerates the recycling refrigerating component, and heats the regenerating heating part at the same time. The system has the advantages that gas to be compressed may be refrigerated, drying quality is good, regenerated gas is recyclable, gas consumption is low and noise is low.

Description

technical field [0001] The invention relates to the technical field of compressed air drying machinery, in particular to a front-end refrigeration and regeneration gas recovery heating system of an adsorption dryer. Background technique [0002] Compressed air is a safe and reliable power source widely used in modern industry. According to statistics, about 90% of manufacturing enterprises use compressed air in various fields of their operation. However, unlike energy gas, water and electricity, compressed air is produced on site. Since the air compression system uses the atmosphere as the gas source, but because the air contains a lot of dust, water vapor and unburned hydrocarbons and bacteria, and the lubrication system of the air compressor itself will also produce pollutants such as wear particles and oil. pollute. [0003] Therefore, according to the quality requirements of the compressed air in the production process, it is necessary to dry the water vapor in the co...
