Deodorant and energy-saving carbon-containing material non-oxidation electric furnace

Abstract

A deodorant and energy-saving carbon-containing material non-oxidation electric furnace comprises a furnace body with an opening formed at least at the upper end, peripheral wall face electric heating elements and a furnace cover sealing the opening at the upper end of the furnace body. An inner cover with a one-way air exhaust function and closing a cavity is arranged on the opening of the furnace body, the furnace cover is positioned above the inner cover, the electric heating elements are electric heating pipes in a split combining and with insulated surfaces, an upper-portion smoke exhaust pipe is arranged on a furnace wall above the inner cover or on the furnace body, a smoke combustion chamber is additionally arranged at the bottom of the furnace body, a baseplate is arranged at the top end of the smoke combustion chamber, and separately seals the smoke combustion chamber and an inner cavity of the furnace body, an outer-portion smoke pipe and an incoming air combustion pipe are arranged on the furnace wall of the smoke combustion chamber, the incoming air combustion pipe is connected with the upper-portion smoke exhaust pipe, and an ignition device extending into the smoke combustion chamber and directly facing an air outlet of the incoming air combustion pipe is further arranged on the furnace wall of the smoke combustion chamber. By the deodorant and energy-saving carbon-containing material non-oxidation electric furnace, energy consumption is greatly lowered, operating cost is saved, peculiar smell of smoke is effectively removed, and environmental pollution is reduced.

Description

technical field [0001] The present invention is a further improvement of the electric furnace for non-oxidation firing of carbonaceous materials with the patent No. 200920045406.6. Background technique [0002] Chinese Patent Publication No. CN201413029 discloses an electric furnace for non-oxidation firing of carbonaceous materials, which is characterized in that there is an inner cover with a one-way exhaust function on the opening of the furnace body to close the cavity, and the furnace cover with exhaust channels is located above the inner cover , The electric heating element is an electric heating tube with split surface insulation. Compared with the existing technology, it eliminates the shortage of using the inner liner, greatly saves heating power, and can save energy by about 30-50%; direct firing without the inner liner can also achieve rapid firing, and at the same time, the original bare electric heating wire will not occur. lack of. By setting a fast cooling t...

Problems solved by technology

This technical solution effectively collects the polluted gas through the inner cover, cools the exhaust gas, and retains it between the inner cover and the furnace cover. Although the pollution is effectively reduced, it needs to be cooled by a cooling device, which requires cooling. Medium, while increasing the operating cost, the energy consumption is also greatly increased, and the heat energy of the original flue gas cannot be effectively recovered, resulting in a large waste of energy, which needs to be improved. Furthermore, although the flue gas is cooled, the removal of A large amount of pollutants, but the exhausted smoke has a strong odor, which pollutes the surrounding environment and has a negative impact on the lives of the surrounding residents.
