Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0040] figure 1It is a schematic flow chart of the continuous impregnation method for the particle carrier provided by the present invention. The specific process is described as follows: the immersion liquid from the pipeline 126 enters the nozzle, is atomized into liquid droplets by the air gas from the pipeline 127, and then sprayed into the atomizer 2 at high speed. The carrier from the pipeline 124 is sucked into the atomizer 2 after passing through the feeder 1. After the liquid droplets and the carrier particles are fully contacted in the atomizer 2, they enter the immersion mixer 3 and are further deepened in the immersion mixer 3. The impregnation process is then sent to the flash dryer 4 after being agitated by the screw and controlling a short residence time. The air from the pipeline 128 enters the heating...

Abstract

The invention relates to a continuous steeping method for a grain carrier and equipment thereof. The continuous steeping method comprises the following steps that steeping liquor is atomized into drops through a nozzle and is jetted into an atomizer; carrier grains are led into the atomizer; the steeping liquor drops and the carrier grains are mixed in the atomizer to form a mixture; the mixture enters into a steeping mixer to carry out sufficient contact; the average grain diameters of the carrier grains are 40-90 microns; the average grain diameters of the steeping liquor drops are 0.5-1.0 time the average grain diameters of the carrier grains; and the ratio of the volume flow of the steeping liquor to the mass flow of the carrier is 0.30-0.60L / kg. The continuous steeping equipment comprises the atomizer and the steeping mixer which is connected with the outlet of the atomizer. The method can implement the continuous steeping process of the grain carrier and can make active component evenly distributed in the carrier, thereby ensuring the strength of an adsorbent finished product.

Description

technical field [0001] The invention relates to a method and equipment for impregnating particulate carriers, more specifically, a continuous impregnation method and continuous impregnation equipment for particulate carriers. Background technique [0002] In modern petrochemical and chemical production processes, many catalysts or adsorbents are prepared by impregnation, that is, the carrier is prepared first, and then the active components are impregnated on the carrier. In the general industrial process, there are two methods of supersaturated impregnation and saturated impregnation. For example, the adsorbent used in adsorption desulfurization technology is an adsorbent loaded with active components on particulate carriers. However, there is no continuous impregnation method and related equipment for particulate carriers in the prior art. [0003] Adsorption desulfurization is one of the important technologies for clean fuel production. Its technological advantages are ...
