Ship and marine engineering painting workshop gas radiant heating system

Abstract

The invention discloses a ship and marine engineering painting workshop gas radiant heating system. The system comprises at least two radiant tube subsystems located in a painting workshop; each radiant tube subsystem comprises a plurality of coaxial heat energy radiant tubes communicating with one another; every two adjacent heat energy radiant tubes are detachably connected; the head ends of theradiant tube subsystems are connected with a radiant heat energy generator; a regulating valve is arranged at the tail ends of the radiant tube subsystems; the tail ends of all the radiant tube subsystems communicate through a central radiant tube subsystem; the central radiant tube subsystem comprises a plurality of coaxial central radiant tubes communicating with one another; every two adjacentcentral radiant tubes are detachably connected; the tail end of the central radiant tube subsystem is provided with a negative pressure fan; and the tail end of the central radiant tube subsystem communicates with the external environment of a painting workshop. The technical bottlenecks caused by modern hull manufacturing and maintenance production are eliminated, and the energy saving and emission reduction targets for ship painting production are well achieved.

Description

technical field [0001] The invention relates to the technical field of gas radiant heating systems, in particular to a gas radiant heating system for ships and offshore painting workshops. Background technique [0002] At present, the temperature protection of workpiece heating process in my country's ship painting workshop and the heating of workshop personnel have always plagued the ship production process. The heating process not only needs to heat the steel and steel section workpiece body that needs to be painted and cured, but must reach the process temperature parameters required for painting, and also provide a heating environment for the workers in the workshop. Ship and offshore painting workshops are called special workshops in the industry, and special methods are adopted for heating and heating. For heating in traditional coating sites, hot convection methods such as boilers and hot air are commonly used for heating, which not only causes serious pollution and ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a gas radiation heating system for ships and marine engineering painting workshops, which effectively solves the serious pollution of the ship painting workshops caused by traditional convective heating methods such as boilers and hot air. Process temperature parameters are difficult to guarantee, causing technical bottlenecks in modern hull manufacturing and maintenance production; at the same time, it solves the huge energy consumption of convective heating caused by indoor and outdoor air exchange coefficients of 6-8 times / h in ship coating production, and ship production The problem of low energy saving and emission reduction indicators
