A composite cooling and heating cycle drying device for industrial gas drying

Abstract

The invention relates to the technical field of industrial gas drying equipment, in particular to a composite cold-heat cycle drying device for industrial gas drying, comprising a cold-drying mechanism, wherein the cold-drying mechanism includes an air storage cylinder, and the top of the air storage cylinder is fixedly connected with an inlet Air port, an exhaust pipe is fixed on the lower outer wall of the air storage cylinder, a refrigeration pipe is fixed around the outer wall of the air storage cylinder, a temperature guide plate is fixedly welded on the inner wall of the air storage cylinder, and the temperature guide plate surrounds Fixed on the inner wall of the air tank. The invention cools the inside of the gas storage cylinder through the refrigeration pipe, so that the moisture in the industrial gas introduced into the gas storage cylinder is condensed into ice crystals. Pre-removal effectively guarantees the dehumidification efficiency of the device, and does not need to use a desiccant to absorb moisture, thereby effectively reducing the operating cost of the device.

Description

technical field [0001] The invention relates to the technical field of industrial gas drying equipment, in particular to a composite cold-heat cycle drying device for industrial gas drying. Background technique [0002] In the existing industrial production, the products that are gaseous at normal temperature and pressure are usually collectively referred to as industrial gases. As an important basic raw material for modern industry, industrial gases are widely used in metallurgy, steel, petroleum, chemical industry, machinery, electronics. , glass, ceramics, building materials, construction, food processing, medicine and medical treatment and other departments have different degrees of application, and industrial gas in the production or construction process, affected by its purity, most of its interior contains a small amount of moisture, making industrial gas The gas is in a wet state. In order to ensure the stability of the industrial gas when it is used, it is usually n...

Problems solved by technology

[0005] The object of the present invention is to provide a combined cooling and heating cycle drying device for industrial gas drying to solve the problem of the prior art industrial gas drying device proposed in the above background technology, which usually adopts desiccant adsorption and electric heating assistance. For dehumidification and drying, during the operation, the desiccant needs to be replaced and maintained regularly, resulting in increased drying costs, cumbersome operation, and poor dehumidification effect due to the influence of the adsorption saturation of the desiccant
