A high-efficiency and energy-saving kiln tube-type vaporization equipment and its control method

Abstract

The invention relates to an efficient and energy-saving kiln tubular vaporization device. The efficient and energy-saving kiln tubular vaporization device comprises a liquid storage tank, wherein the liquid storage tank is connected with a set of vaporization pipes through a liquid adding pipe provided with a high pressure liquid adding pump, the vaporization pipes are connected in series or in parallel, a vaporization chamber is arranged at the upper portion in the vaporization pipes, a vaporization liquid chamber is arranged at the lower portion in the vaporization pipes, a pressure sensor, an electric contact vacuum pressure gauge and an overpressure exhaust pipe are connected to the upper portions of the vaporization pipes, an electrical heating base attached to the bottoms of the vaporization pipes is arranged at the lower portions of the vaporization pipes, the two ends of each vaporization pipe are closed and are respectively provided with a liquid level meter communicated with the interior of the vaporization pipe, a temperature sensor is arranged on the electrical heating base, and a temperature sensor is arranged inside the vaporization pipes. The efficient and energy-saving kiln tubular vaporization device has the advantages that the liquid adding amount can be adjusted and controlled, and the liquid is added once being used; the liquid level is controlled strictly so that vaporization pressure can be stable relatively; a liquid level alarm and a master power source which is cut off when the liquid level is exceeded are arranged, so that safety accidents caused when the liquid is not enough or the liquid is excessive are avoided; the device can be suitable for various kilns and used for vaporizing petroleum gas, and can also be used for vaporization isolation and purification of chemical production liquid, or rectification purification of mixed liquid.

Description

technical field [0001] The invention relates to an industrial liquid vaporization device and method, in particular to a high-efficiency energy-saving kiln tube type vaporization device and a control method thereof. Background technique [0002] At present, energy-saving and environment-friendly fuels are the goals pursued by human society. C5 to C10 are by-products of the petrochemical industry, and their utilization rate has been very low. For many years, people have been making an attempt to use one of C5 to C10 as a fuel gas raw material, such as adding methanol, dimethyl ether, and ether to C5, and these components are neutral poisonous substances, which have been The country expressly prohibits it; there is also the transportation of refined carbon five and heating pipes side by side, using its heat to heat, so that carbon five can reach saturated vapor pressure, and can be fully burned when used, but due to uneven heating temperature, the degree of combustion is incon...
