Embodiment 1

[0031] by attaching Figure 1-3 It can be seen that the present invention is a heatless adsorption air dryer for a locomotive air compressor, comprising 6 adsorption towers 5, the adsorption towers 5 are modular structures, and the upper filter group 6 and the anti-loosening spring of each adsorption tower 5 are 7. The upper positioning filter screen 8 and the positioning retainer 9 are installed on the upper inner surface of the adsorption tower 5, the lower filter combination 3 and the axial positioning retainer 4 are installed on the lower inner surface of the adsorption tower 5, and the upper filter group 6 and the lower filter combination 3 are integrated with the cylinder body of the adsorption tower 5 and the adsorption material 11 to form an adsorption tower module. The six adsorption tower modules are divided into two groups and installed between an upper cover plate 10 and a lower cover plate 2. The upper cover plate 10 and the lower cover plate 2 are respectively co...

Embodiment 2

[0038] The basic composition principle of Embodiment 2 is the same as that of Embodiment 1, except that there are 4 adsorption tower modules, and the 4 adsorption tower modules are divided into two groups, which are installed obliquely between the upper cover plate and the lower cover plate respectively. , when one group is adsorbed, the other group is regenerated. An electric control valve is provided on the lower cover plate to change the inlet or outlet channel of the adsorption tower module, so that the adsorption tower module can alternately perform adsorption or regeneration. Through the electric control valve The automatic control of the adsorption tower module makes the adsorption or regeneration work alternately.

[0039] The automatic control is to install an electric control device on the electric control valve, and the electric control valve is controlled by the electric control device to perform switching operations; the electric control device is controlled in seq...

Embodiment 3

[0042] The basic composition principle of the third embodiment is the same as that of the first embodiment, except that the adsorption tower module is installed horizontally and horizontally, and the upper cover plate and the lower cover plate at both ends of the adsorption tower module become the right cover plate and the left cover plate respectively. And the electric control valve is installed on the right cover plate, through the automatic control of the electric control valve, the adsorption tower module can perform the alternate operation of adsorption or regeneration.

[0043] The automatic control is to install an electric control device on the electric control valve, and the electric control valve is controlled by the electric control device to perform switching operations; the electric control device is controlled in sequence by a PLC controller, and the PLC controller adopts programmable logic control Technology, through the control of the dew point temperature at th...

Abstract

A method of drying humid air and a modular air dryer, used to treat humid air by means of adsorption; adsorbers used for treating humid air comprise a plurality of adsorbers (5), each adsorber (5) being a modular adsorber, and the plurality of modular adsorbers (5) being combined to dry the humid air. The air dryer comprises two or more adsorbers (5), the adsorbers (5) having modular structures; a filter of each adsorber (5) is integrated with the adsorber barrel to form an adsorber module; all adsorber modules are installed between an upper cover plate (10) and a lower cover plate (2), the upper cover plate (10) and the lower cover plate (2) being respectively connected to two ends of the barrel of each adsorber module, and being used as an air inlet channel and an air outlet channel of the adsorber module. The adsorber modules are combined with the upper cover plate (10) and the lower cover plate (2) to form a modular heatless adsorption air drying system of an air compressor to perform heatless adsorption air drying on the compressed air expelled by the air compressor.

Description

technical field [0001] The invention relates to a wet air drying method and device for a locomotive air compressor, in particular to a heatless adsorption drying method and device for a locomotive air compressor; it is mainly used for drying the wet air sent and discharged by the locomotive air compressor . Background technique [0002] The basic working principle of the heatless adsorption air dryer is the "pressure swing adsorption" method. When the compressed air with water passes through the adsorption bed at high pressure, the adsorbent adsorbs moisture, and the moisture in the adsorbent is "desorbed" at low pressure. Back in the gas phase, the adsorbent is thus dehydrated and "regenerated". The regenerated and desorbed air comes from a part of the dry gas output by the machine. The main body of the heatless adsorption air dryer currently used is composed of two adsorption towers, an intake valve, an exhaust valve, a blowdown valve, an outlet check valve, an electric ...
