Problems solved by technology
[0003] The purpose of the present invention is to solve the problem that although the waste heat regeneration adsorption dryer makes full use of the waste heat of the compressed air for regeneration to achieve low emissions, it needs to consume 1% of the finished product gas for blowing and cooling during the cooling process of the equipment, resulting in the loss of compressed air. The problem is to provide a waste heat regeneration adsorption dryer with reasonable structural design. According to the principle of Bernoulli equation, the drainage device is used to use the waste heat of gas compressed air to heat the adsorbent, and the adsorbent is completely regenerated, so that the product gas The pressure dew point is below -60°C, realizing low emission of compressed air, saving energy and reducing emissions, and improving energy utilization

The invention relates to technical field of desiccators, in particular to an afterheat regeneration absorbing type desiccator, which solves the problem to regenerate the afterheat of compressed air of the afterheat regeneration absorbing type desiccators to realize low emission. The afterheat regeneration absorbing type desiccators comprises a compressed air supply station, and two parallel drying towers A and B, and is characterized in that: one end of the drying tower A and one end of the drying tower B are provided with three groups of parallelly connected pneumatic valves and are connected with a compressed air outlet; the other ends of the drying towers A and B are provided with three pneumatic valve banks which respectively consist of two serially connected pneumatic valves and are connected in parallel; and a drainage device is arranged in a main pipeline for conveying compressed air from the compressed air supply station to the other ends of the drying towers A and B. The device is simple in structure; and in the working process, electric energy is not needed, so energy is saved and emission is reduced.
Description
technical field [0001] The invention relates to the technical field of dryers, in particular to a waste heat regeneration adsorption dryer. Background technique [0002] Although the waste heat regeneration adsorption dryer makes full use of the waste heat of compressed air for regeneration to achieve low emissions, it needs to consume 1% of the finished product gas for blowing cooling during the cooling process of the equipment, resulting in the loss of compressed air. For example, the patent announcement number is CN201815226U, an energy-saving waste heat regeneration air dryer, which is composed of a valve, a water cooler, an oil-water separator, an adsorption tower, a dust filter, a pipeline, and a tee. By using two adsorption towers, the adsorption tower The upper and lower ends are equipped with control facilities for the upper and lower joint control of the gas flow direction, forming and switching the main compressed air passage and the small compressed air passage, ...
