Automatic draining heat exchanger with screw extruding pipes

Abstract

The invention discloses an automatic draining heat exchanger with screw extruding pipes. The automatic draining heat exchanger comprises a heat exchanger shell, the two ends of the upper side wall ofthe heat exchanger shell are each provided with a shell connecting pipe, a left pipe plate and a right pipe plate are arranged on the end faces of the two ends of the heat exchanger shell respectively, a heat exchanger pipe core is arranged in the heat exchanger shell in a penetrating mode and composed of multiple screw extruding pipes, grooves are formed in the outer walls of the screw extrudingpipes in a winding mode, and protrusions are arranged on the inner walls of the screw extruding pipes in a winding mode; a water accumulating bag is arranged in the middle of the lower side of the heat exchanger shell in a cut-through mode, and the lower end of the water accumulating bag communicates with an automatic draining valve; and multiple partition plates are vertically arranged in the heat exchanger shell in a staggered mode and sleeve the exteriors of the screw extruding pipes. According to the automatic draining heat exchanger with the screw extruding pipes, the heat exchange capability is improved, the production cost is reduced, generation of scales is avoided, corrosion is not prone to occurring, the service life is long, and the production requirements can be better met.

Description

【Technical field】 [0001] The invention relates to the technical field of heat exchangers, in particular to a spiral extruded tube automatic drainage heat exchanger. 【Background technique】 [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. However, most of the core tubes used in the existing heat exchangers are bare tubes, which have limited heat exchange capacity, and it is difficult to drop the cooling temperature below 40°C. The heat exchange performance cannot better meet the production requirements. Enterprises improve the light pipe, but its structure is relatively complicated, the production proce...

Problems solved by technology

However, most of the core tubes used in the existing heat exchangers are bare tubes, which have limited heat exchange capacity, and it is difficult to drop the cooling temperature below 40°C. The heat exchange performance cannot better meet the production requirements. Enterprises improve the light pipe, but its structure is relatively complicated, the production process is cumbersome, and the production cost is high

Furthermore, the existing heat exchanger is not drained thoroughly, causing premature scaling inside the heat exchanger, even corrosion, and a short service life
