The present invention relates to a heat storage type electric steam boiler using heat treatment oil, salt for salt bath, automobile engine oil, etc. as heat storage medium having a higher specific heat and boiling point than water, and using heat of the heat storage medium effectively without a separate heat exchanger. It is an object of the present invention to provide a regenerative electric steam boiler which is simple in structure and easy to manufacture and install, and can also reduce manufacturing costs by allowing steam to be produced and supplied.

An electric steam boiler is a device for generating water vapor by heating water supplied into a steam generating tank with heat energy converted from electric energy. Korean Utility Model Registration No. 20-0247503, Korean Patent Application Publication No. 2002-0013018, Korean Patent Application Publication No. 1999-0079424 and Korean Utility Model Publication No. 94-13123 disclose various electric steam boilers. These steam generators generally include steam generating tanks for receiving the introduced water and steam generated from the water, and heating the water supplied into the steam generating tanks by converting electrical energy into thermal energy.

It includes an installed heater, and a water level sensor for detecting the water level inside the steam generating tank. In the conventional electric steam boiler, water is directly supplied to the inlet of the steam generating tank, and steam generated by heating the water is supplied to a predetermined steam using device through the steam outlet. Meanwhile, the electric steam boiler disclosed in Korean Utility Model Registration No. 20-0247503, Korean Patent Application Publication No. 2002-0013018, and Korean Patent Application Publication No. 1999-0079424 uses a rod-shaped heater rod as the heater. An embodiment is disclosed. In general, the heater rod is used as a heater of the electric steam boiler because of its simple structure and shape and easy replacement. The heater rod is installed in the steam generating tank so that the heat generating portion is exposed to the steam generating tank and submerged in water.

In the rapidly changing energy situation, the oil boilers used in the past are affected by the increase in oil prices. Some electric steam boilers were supplied. However, in the case of electric steam boilers used in the related art, the weight and volume of boilers were too large, which made it difficult to install or move the boiler. It requires a lot of water to generate high pressure steam, and requires a lot of time and a lot of capacity to produce high pressure steam. It seems that users need a lot of power In addition to the waste of energy for the operation of the boiler, such as paying a lot more cost to meet the conditions of use, there was a problem that can not be used because there are a lot of constraints on the space and conditions to install the boiler.

In the heat storage electric steam boiler configuration, the heat medium that can store heat inside the circular tank is heated and stored, and the pipe which is banded is installed in the part in contact with the heated heat medium. The in-line mixer is installed inside the pipe. Regenerative electric steam boiler characterized in that the steam is stored in the storage tank while moving along the installed steam generating pipe

As described above, the present invention can reduce the electric power consumption of the boiler by producing steam by heat storage of the heat source during the boiler downtime in the electric steam boiler used in the laundry brick factory sewing factory feeding facilities, etc. In case of application, it can reduce the power installation cost. Also, steam is generated immediately when water is supplied to the boiler according to the required amount of steam. Therefore, it is possible to prevent the occurrence of melt or silica lime due to the concentration of water in the existing boiler. Since there is no wealth, it can prevent rupture and explosion to prevent damage to life or property.

Electric steam boiler according to the present invention for achieving the above object, the steam storage tank, a plurality of rod-shaped heater rods installed in the tank to heat the heat medium contained in the boiler by converting electrical energy into thermal energy, and In a regenerative electric steam boiler equipped with several connected steam generator tubes mounted inside a tank,

The plurality of heater rods are disposed in a plurality of layers having different heights, at least one heater rod is arranged in a predetermined direction in each of the plurality of layers, and a steam generating tube equipped with an in-line mixer is arranged between the adjacent layers. It is characterized in that it is installed in the tank not parallel.

The arrangement direction of the heater rods is not parallel to each other between the adjacent layers. That is, the arrangement direction of the heater rod and the steam generating tube is twisted between the adjacent layers. Therefore, even when the tank is viewed from above, the portion where the heating medium is heated is evenly distributed.

Will be. In addition, the portion where the heater rod of the upper layer and the heater rod of the lower layer overlap in the vertical direction is reduced. Accordingly, since the convection of the heat medium inside the tank is made smoothly, heat storage and heating are performed in a short time.

In addition, a steam storage tank is installed above the heating medium heating tank,

The steam generating pipe installed inside the tank is connected to the inline mixer feed water heater.

Characterized in that the water supplied is preheated

Accordingly, even if water is supplied into the steam generating tube, the inside of the heat medium storage tank

The temperature of the heat medium drops rapidly and the amount of steam does not decrease rapidly.

The heat medium storage tank is divided into an upper steam storage tank, and the steam chamber and the heating chamber are connected to a steam induction pipe passing through the diaphragm, and water vapor generated in the heating chamber is moved to the steam chamber through the steam induction pipe.

Hereinafter, with reference to the embodiment shown in the drawings will be described in detail the heat storage electric steam boiler according to the present invention.

The regenerative electric steam boiler (1) is a cylindrical container for heating the water inside the steam generating tube (3) installed in contact with the heat medium oil and the heat medium oil supplied therein.

 In general, in the steam storage tank (8) mounted on the top of the regenerative electric steam boiler (1) is provided with a main steam side (9) connected to a predetermined steam using device (not shown in the figure) via a conduit.

The heater rod 2 is for heating the heat medium supplied into the steam generating tank 10 by converting the electrical energy into thermal energy by receiving electrical energy. The heater rod 2 has a rod shape, one end of which is exposed to the inside of the heat storage electric steam boiler (1) and the other end is exposed to the outside of the heat storage electric steam boiler (1). Is installed on the cylindrical wall. The other end of the heater rod (2) exposed to the outside of the heat storage electric steam boiler 10 is provided with a terminal for connecting a wire connected to the power source, when the electric energy is supplied through the heat storage electric steam boiler Heat is generated at one end of the heater rod 2 exposed to the inside of (1).
