Dense-phase filling machine for methanol synthesis catalyst

Abstract

The invention discloses a dense-phase filling machine for a methanol synthesis catalyst. The machine can comprises a barrel body, an upper fixed plate, an upper filter plate, a lower filter plate anda filter screen are fixedly mounted in the barrel body in sequence from top to bottom; a lifting rod is fixedly mounted on the inner side of the upper opening of the barrel body; a discharging openingpenetrating up and down is formed in the middle of the upper fixing plate, densely-distributed through holes are formed in the upper end face of the upper filtering plate, a base plate is fixedly installed at the bottom of the barrel body, three supporting legs are fixedly installed on the side edge of the bottom of the base plate in an annular array mode, and discharging holes distributed at equal intervals are formed in the bottom of the base plate. The invention discloses the dense-phase filling machine for the methanol synthesis catalyst, which is simple in overall structure, the overallstructure is made of 304 stainless steel, the overall weight is reduced while the performance is met, meanwhile, the overall structure is in welded connection, the stability is extremely high, meanwhile, the overall structure can be spliced to form the catalyst dense-phase bed of the methanol synthesis tower, the working area is increased, the efficiency is improved, and the dense-phase filling machine is convenient to use.

Description

technical field [0001] The invention relates to the technical field of dense-phase filling machines, in particular to a dense-phase filling machine for methanol synthesis catalysts. Background technique [0002] The main application field of methanol is the production of formaldehyde. Formaldehyde can be used to produce adhesives, mainly used in the wood processing industry, and secondly used as a treatment agent for molding compounds, coatings, textiles and paper. Methanol is one of the basic organic raw materials. Manufacture of various organic products such as methyl chloride, methylamine and dimethyl sulfate, as well as raw materials for pesticides (insecticides, acaricides), medicines (sulfonamides, synamycin, etc.), and synthesis of dimethyl terephthalate , one of the raw materials for methyl methacrylate and methyl acrylate. [0003] But so far, the catalyst loading of the methanol synthesis tower is based on the method of manual scattering. The methanol synthesis to...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of methanol synthesis catalyst dense-phase filling machine, to solve the problem mentioned above in the background technology, the catalyst loading of methanol synthesis tower is all based on the mode of artificial sprinkling. The methanol synthesis tower is a tubular shell, and the catalyst The filling needs to be evenly distributed in the tubes, so that the material flow is smooth and even during the production process. The human operation error is large, and the filling quality cannot be guaranteed to meet the requirements at one time. The impact is that the device cannot maintain long-term, full-load operation. The service life of the catalyst will also be greatly affected by the problem
