Efficient energy-saving anti-explosion electric heater

Abstract

The invention discloses an efficient energy-saving anti-explosion electric heater which comprises an anti-explosion junction box. The anti-explosion junction box is of a barrel structure with one end open, a plurality of anti-explosion cavities are formed in the anti-explosion junction box, a plurality of power interfaces are formed in the outer side of the anti-explosion junction box, an anti-explosion cover is arranged on the left side of each anti-explosion cavity, the explosion-proof cover is matched with the opening end of the explosion-proof junction box to seal the explosion-proof cavity, and the right side of the explosion-proof junction box is provided with a cooling cavity. According to the electric heater, fluid is used for cooling connecting pipes of first heating elements, second heating elements and third heating elements, the influence on the interior of the explosion-proof junction box is reduced, meanwhile, a proper number of the first heating elements, the second heating elements and the third heating elements can be selected to work according to the final temperature needed by a medium, flowing of internal fluid is reasonably controlled through the change of internal air pressure and the arrangement of the high-pressure cavity, the problem of slow response caused by too long stroke is avoided, and the explosion-proof effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electric heating equipment, in particular to a high-efficiency energy-saving explosion-proof electric heater. Background technique [0002] Explosion-proof electric heater is a kind of equipment that converts electricity into heat energy for explosion-proof occasions. In recent years, in the fields of petroleum and chemical production, storage and transportation, it is often necessary to heat and dilute crude oil or chemical liquid media to enhance their fluidity, and at the same time require certain explosion-proof performance. [0003] In the process of heating the fluid with the existing explosion-proof electric heater, due to the long heating path, when the internal temperature changes quickly, it is too late to respond, causing the local temperature to be too high, and the heating device is lost. Moreover, the temperature of the heater is transmitted to the explosion-proof box Inside, low security. ...
