Solid heat storage electrode boiler

Abstract

The invention relates to the technical field of electrode boilers, and particularly relates to a solid heat storage electrode boiler comprising a boiler body, a heating and heat storage device which is arranged in the boiler body, inert gas filling in the boiler body, a circulating pipeline communicated with the boiler body and a heat exchanger which is installed on the circulating pipeline and connected with the user. The heat storage medium of the heating and heat storage device is made of a solid material, and heat stored by the heating and heat storage device comes from heat generated by resistance of the heating and heat storage device after the heating and heat storage device is powered on. The boiler has the advantages that heating and heat storage are integrated, the size of the whole heating and heat storage device can be greatly reduced, safety and reliability are high, the structure is simple, cost is low and steam with higher temperature can be outputted.

Description

technical field [0001] The invention relates to the technical field of electrode boilers, in particular to a solid heat storage electrode boiler. Background technique [0002] The traditional electrode hot water boiler is a device that uses the high thermal resistance of water to directly convert electrical energy into heat energy and raise the temperature of the water. If the water volume inside the boiler is large enough, water can be used to store heat; however, since the heat storage capacity of water is small, a large hot water storage tank must be configured for large-capacity heat storage applications. The total volume of the electrode hot water boiler, hot water storage tank and related pipelines is very large. [0003] The electrode boiler can also be made into a form of steam supply, that is, it can be made into an "electrode steam boiler" to provide users with steam. According to the characteristics of water, the pressure of water vapor rises faster than the tem...

Problems solved by technology

At present, the better and most commonly used solid heat storage material is "magnesia brick". control, the use of this material is an unsustainable practice

In addition, this solid heat storage method uses "resistance wire heating element" for heating. Due to the low reliability of this heating element, it is easy to be blown out, thereby increasing the maintenance workload and maintenance cost. In addition, it also increases the maintenance space. As a result, the total installation space is too large
