The invention discloses an electrode roasting furnace with a lid in the field of graphite electrode production, particularly relates to a furnace floor flue gas channel structure of the electrode roasting furnace with the lid. The furnace floor flue gas channel structure is realized by the following steps: an ondol pier is arranged between a furnace floor masonry and ondol surface bricks and is composed of an upper ondol pier brick section and a lower ondol pier brick section. The calandria arrangement in the furnace floor flue gas channel that is formed by the ondol pier bricks with circularsections greatly lowers the local resistance loss of flue gas. As the furnace is a running system consisting of a plurality of furnace chambers, the accumulated reduction value of local resistance loss is very remarkable. As section size of the ondol pier bricks is reduced and the calandria flue gas channel structure is additionally arranged, the flue gas circulation area in the channel is increased, and the friction resistance loss in the flue gas circulation process is effectively reduced.

The invention provides a high-efficiency and high-precision measurement experimental device for a natural convection heat transfer coefficient. The device comprises a unit-pipe pipe wall, a primary heating rod, an auxiliary heating rod, an insulating sheet, a heat-insulation jacket, heat-isolation end covers, a film thermocouple, terminal sleeves, an A / D (Analog / Digital) converter, a computer, a control box and a bracket. The insulating sheet is inserted between the primary and auxiliary heating rods of the device to form close connection; pipe cavities at an effective experimental section and an auxiliary experimental section which are corresponding to the primary and auxiliary heating rods respectively are spaced by using the annular heat-insulation jacket; the temperatures of the adjacent terminal sleeves of the primary and auxiliary heating rods are controlled to be the same through regulating the current and the voltage of the auxiliary heating rod, so as to reduce the axial heat loss of the primary heating rod; the internal surface silvered heat-isolation end covers are sleeved at each unit-pipe port; high-temperature-resistant heat-isolation foam mats are filled in gaps among the heat-isolation end covers and unit pipes, so as to reduce the heat loss due to radiation at an auxiliary-section port; the external surfaces of the unit pipes are slivered, and the internal surfaces of the unit pipes are plated with high-radiance materials, so as to shorten an experimental time.

The invention discloses an electric heat preservation and decoration integrated wall and floor tile and a preparation method thereof. It is a combination of brick base layer mixture (components: clay, quartz, feldspar and pigment), non-metallic conductive layer mixture (components: carbonaceous materials, clay, iron raw materials and feldspar) and foamed ceramic insulation. The layer mixture (components: solid waste, feldspar, clay and foaming agent) is sequentially distributed, pressed by a press to form a green body, and the green body is fired at a high temperature in a kiln after drying. The floor tile has the advantages of small heat loss, electric heating efficiency up to 99%, and simple construction, which can reduce construction and use costs to a certain extent.

The present invention provides a valley power application control device and method based on phase-change energy storage. More than one heat storage floor is set in the heating area, and the phase-change heat storage bricks and carbon fiber heating modules in the heat storage floor are set as Can be separated and combined. The temperature master control device determines the accurate heat storage time according to the infrared data, pressure data, video data and other data in the heating area. After the heat storage is completed, the phase change heat storage brick and the carbon fiber heating module are separated, and the heat storage is stopped to realize heat storage. Accurate control of time reduces power consumption during off-peak periods. During the peak period of electricity consumption, the heat stored in the heat storage floor is used for heating, and the temperature master control device determines that the heating area is a vacant area or an active area. When the heat storage time or heat storage is reached in the vacant area, the phase change heat storage brick and carbon fiber The heating module is separated to stop heat storage, reduce heat consumption and heat storage time, realize accurate control and distribution of heat storage and heating power, and further save electric energy.
