Suspension type steam generator

Abstract

The invention relates to a suspending steam generator, with saved energy, high steam generating speed, continuous operation, and lower cost. It comprises a container (1), a float (2), and an electric heater (3). Wherein, the float (2) is fixed on the upper part of said container (1); the top of container (1) is open while the bottom has a through hole (4); the wall of container is made from thermal-insulated material or adhered with thermal-insulated layer (5); and the electric heater (3) is inside the container (1). The invention has wider application to generate steam.

Description

technical field [0001] The invention relates to a steam generator, in particular to a steam generator which utilizes electric heat to produce steam. Background technique [0002] Most of the existing electrothermal steam preparation methods use the direct heating method, that is, the electric heater is directly installed on the bottom of the water storage container or in the water to heat the water and boil the water in the entire container to generate steam. . At present, this method of preparing steam is widely used in daily life and industrial and agricultural production. For example, steamers, steam cabinets, electric boilers, and fresh water preparation used in the catering industry all use this method to prepare steam. This steam generator exists The following deficiencies: [0003] 1. Waste of energy: The water in the entire container must be boiled first to obtain steam. If the container is large and the water storage capacity is large, ...

Problems solved by technology

[0003] 1. Waste of energy: The water in the entire container must be boiled first to obtain steam. If the container is large and the water storage capacity is large, it will take a long time and consume a lot of energy. If a small amount of steam is needed in a short time, it will The waste of energy is more obvious; the electric heater is placed at the bottom of the water to heat the water, and the hot water at the bottom exchanges heat with the cold water when it rises, which will consume the internal energy of the water molecules, and part of the energy will be wasted; now Some direct-heating steam generators are made of metal shells, and no heat preservation measures are taken, so that the heat inside the steam generator is dissipated through the metal shell, resulting in a large loss of energy and a waste of energy.

[0004] 2. The speed of steam production is slow: the water in the entire container must be boiled first to obtain steam. If the container is large and the water storage capacity is large, it will take a long time to obtain steam, which affects production and living efficiency

[0005] 3. Unable to generate steam continuously: In the process of producing steam, with the generation of steam, the water will continue to decrease. In order to prevent dry burning, the existing direct-heating steam generator needs to inject cold water into the steam generator intermittently. This will cause the steam generator to cool down, so that the water inside it cannot maintain a continuous boiling state, and it will cause intermittent stop of steam production during use; in addition, it is impossible to replace the water in the water storage container while producing steam, which will directly Affect industrial and agricultural production and daily life

[0006] 4. It is easy to generate scale, which increases safety hazards and increases operating costs: scale is produced during the intense heat exchange between the heating surface of the heater and water. The solubility of calcium, magnesium and other salts in water will not increase with the increase of temperature. Due to the large amount of boiling and evaporation of water, this kind of salt will directly crystallize and form scale on the heating surface.

The impact of scale on boilers is fatal, especially for steam boilers. Scale is the main cause of explosion accidents and destructive power. It can be seen that this traditional heating method has great potential safety hazards and increases the cost of operation and maintenance.
