Abstract
The utility model provides a heating device for use in crude benzene hydrogenation production technology, includes the heating unit, and the heating unit setting is on the lateral wall of the cauldron body, and the key is: the heating unit include upper portion heating unit, middle part heating unit and lower part heating unit, the upper portion heating unit is located the upper portion of the cauldron body, the middle part heating unit is located the middle part of the cauldron body, the lower part heating unit is located the lower part of the cauldron body, the height of heating unit heating region in the middle part of highly all being less than of the height of upper portion heating unit heating region and lower part heating unit heating region. Three heating unit heats the liquid of upper portion, middle part and lower part in the reation kettle respectively, and rate of heating is fast, and the heating is even, and the energy can be saved has improved the quality of product.
Description
Technical field
The utility model belongs to firing equipment technical field, relates to the heater in a kind of crude benzole hydrogenation production technology.
Background technology
In crude benzole hydrogenation production process, need to utilize heater to heat the liquid in reactor, present mode of heating is overall heating or bottom-heated, firing rate is slow, heat uneven, temperature near the temperature of liquid level partially liq and close reactor bottom liquid in reactor is inconsistent, affects the quality of product.
Summary of the invention
The utility model, in order to overcome the defect of prior art, devises the heater in a kind of crude benzole hydrogenation production technology, and firing rate is fast, homogeneous heating, saves the energy, improves the quality of product.
The concrete technical scheme that the utility model is taked is: the heater in a kind of crude benzole hydrogenation production technology, comprise heating unit, heating unit is arranged on the lateral wall of kettle, key is: described heating unit comprises top heating unit, middle part heating unit and lower heating unit, top heating unit is positioned at the top of kettle, middle part heating unit is positioned at the middle part of kettle, lower heating unit is positioned at the bottom of kettle, the height in heating unit heats region, top and the height of lower heating unit heating region are all less than the height in heating unit heats region, middle part.
Described kettle madial wall is provided with multiple nozzle, sets up source of the gas, the air inlet of nozzle is communicated with the gas outlet of source of the gas, and the gas outlet end of upper nozzle is obliquely installed downward, and the gas outlet end of lower nozzle is obliquely installed upward.
The gas outlet place of described source of the gas is provided with valve, and the air inlet place of each nozzle is also provided with valve.
The height in described heating unit heats region, top is 1:(1.5 ~ 2 with the ratio of the height in heating unit heats region, middle part).
The height of described lower heating unit heating region is also 1:(1.5 ~ 2 with the ratio of the height in heating unit heats region, middle part).
The beneficial effects of the utility model are: heating unit is by top heating unit, middle part heating unit and lower heating unit three part composition, three heating units are respectively to reactor internal upper part, the liquid of middle part and bottom heats, the mode that this three parts heat simultaneously, firing rate is fast, heat more even, the height in heating unit heats region, top and the height of lower heating unit heating region are all less than the height in heating unit heats region, middle part, the heat of mid portion can transmit with below upward, further increase the efficiency of heating surface, improve product quality.
