Problems solved by technology

The disadvantage of the existing technology is that the system must have an external heating source, and the process needs to consume a lot of heat, resulting in a waste of resources
In addition, the existing desiccant is generally equipped with a cooler, the cooling effect is not good, and the existing adsorption tower is generally filled with a single layer of adsorbent, or two layers of activated alumina or molecular sieve, the adsorption effect is not good , which greatly affects the drying effect

Abstract

The invention belongs to the field of chemical equipment, and particularly relates to a waste heat regeneration absorption dryer. The waste heat regeneration absorption dryer comprises an air compressor, an absorption tower A, an absorption tower B, a first cooler, a second cooler, and a gas-water separator; valves of the absorption tower A and the absorption tower B are symmetrically arranged and use compressed air in the air compressor as a heat source during use, and the absorption tower A and the absorption tower B circularly work under programmed control. The waste heat regeneration absorption dryer fully utilizes waste heat of the compressor so that the power consumption of an electric heater, a fan and a steamer of traditional external heating or microheating drying is saved to achieve the external heating regeneration and maximally reduce the energy consumption; the two coolers are arranged so that the cooling effect is good; and the absorption towers have three-layer structures, and gas flow is distributed uniformly in a molecular sieve layer and an aluminum oxide layer under the action of a large water-absorption ball layer, so that the absorption time is prolonged, the absorption effect is enhanced, the gas flow is stable and uniform, the impact force on a sorbent is small, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a waste heat regeneration adsorption dryer. Background technique [0002] Under the increasingly tense situation of global available resources, the compressed air purification industry has attracted more and more attention. The use of compressed air as a power source is widely used in all walks of life. As the market competition becomes more and more fierce, the requirements for compressed air are increasing. higher. Therefore, it is necessary to purify and dry the compressed air. The compressed air flowing out from the air compressor of the existing dryer must first pass through coolers, gas-liquid separators, heating adsorption drying, etc., and can only enter the gas system after being treated by multiple temperature adjustment and purification devices. The heating adsorption drying process is a cyclic use process of adsorbent adsorption and desorption regenerat...
