Abstract
The utility model discloses a methanol production system with a dewaxing function, which comprises a methanol synthetic reactor with a feed hole and a discharge hole, wherein the discharge hole of the methanol synthetic reactor is connected with a gas/gas heat exchanger, a water cooler and a methanol separator in sequence through a working line; a feedback hole of the methanol separator returns the methanol synthetic reactor through a circulator and the gas/gas heat exchanger from a feedback line; and a wax separator is connected to the working line between the gas/gas heat exchanger and the water cooler. The utility model has the advantages that before wax enters the water cooler, the wax is separated from the methanol production system by the wax separator, the water cooler can always maintain in a high efficiency condition, and thus, safe and stable production of equipment can be guaranteed, the working efficiency is improved, the production is much more environmentally-friendly, and the consumption of energies, such as water, electricity and the like, can be greatly saved.
Description
Technical field
The utility model relates to a kind of methanol production system that has the paraffin removal function.
Background technology
No matter methyl alcohol be the single alcohol of low pressure in process of production, press in still, high-pressure combined methanol all more or less meeting produce wax.Because the technological temperature that comes out from gas-gas heat exchanger is at 90 ℃-110 ℃, under this working condition, methyl alcohol and other gaseous constituents all remain gasiform, and wax liquefy, be brought in the water cooler under the drive of these wax by products gas in service pipe, because water cooler is a cooling system, wax is become solid-state in water cooler by liquid state, stick on its tube wall, solidify accumulation for a long time, had a strong impact on the heat exchange efficiency of water cooler, so just need constantly to increase water consumption, power consumption guarantees cooling performance, it is required that water cooler then can't satisfy production when wax deposition was serious, had a strong impact on the stability and the security of ordinary production.At this moment just can only be forced to stop wax in the cleaning water cooler causes enterprises production efficiency to reduce, and has had a strong impact on product production.
Summary of the invention
The purpose of this utility model is to provide a kind of wax of can avoiding to stop up water cooler, guarantees the methanol production system that has the paraffin removal function that produces steady in a long-term.
For achieving the above object, the utility model can be taked following technical proposals:
The methanol production system that has the paraffin removal function described in the utility model comprises the methyl alcohol synthetic reactor that has the charging and discharging mouth, and the discharge port of described methyl alcohol synthetic reactor is connected with gas-gas heat exchanger, water cooler, methanol separator successively by working line; The feedback outlet of described methanol separator returns in the methyl alcohol synthetic reactor through circulator, gas-gas heat exchanger by recycling pipeline; On the working line between described gas-gas heat exchanger and the water cooler, be connected with the wax separator.
Advantage of the present utility model is to be connected with the wax separator on the working line between gas-gas heat exchanger and the water cooler.So promptly can before entering water cooler, wax just from the methanol production system, not be separated by the wax separator, make water cooler at concert pitch always, not only guaranteed the production that device security is stable, improved working efficiency, and make and produce more environmental protection, saved the consumption of water, electric equal energy source greatly.The utility model shows in the The actual running results of enterprise, can solve the problem that influences the water cooler long-time running because of wax substantially, reduce water consumption 20%, and water cooler can macrocyclicly be controlled at below 35 ℃, have the good performance of enterprises, environmental benefit and energy-saving benefit.
Description of drawings
Fig. 1 is a system chart of the present utility model.
Embodiment
As shown in the figure, the methanol production system that has the paraffin removal function described in the utility model, comprise the methyl alcohol synthetic reactor that has the charging and discharging mouth, the discharge port of described methyl alcohol synthetic reactor is connected with gas-gas heat exchanger, water cooler, methanol separator successively by working line; The feedback outlet of described methanol separator returns in the methyl alcohol synthetic reactor through circulator, gas-gas heat exchanger by recycling pipeline; On the working line between described gas-gas heat exchanger and the water cooler, be connected with the wax separator.
After material enters methyl alcohol synthetic reactor, synthetic methyl alcohol enters gas-gas heat exchanger with 250 ℃ high temperature, cool the temperature between 90 ℃-110 ℃, under this working condition, methyl alcohol is gasiform, and wax is liquid, just it is separated in pipeline before liquid wax enters water cooler at the wax separator of this setting, no longer include wax on the inner-walls of duct of water cooler and adhere to, the working efficiency of water cooler is just no longer influenced by wax.Methyl alcohol is reduced to below 35 ℃ through water cooler, enters methanol separator and separates, and finished product is collected, the intact gas of unreacted by recycling pipeline through circulator, gas-gas heat exchanger reclaimed by methyl alcohol synthetic reactor and new material synthetic once more together.During actual the use, the wax separator can be selected static equipment for use, also can select running device (as mechanical inertial separator or centrifugal overweight separator) for use.During normal operation, per tour is separable to go out wax 2-4Kg, separation efficiency reaches 99.5%, has fundamentally solved wax is solidified accumulation in water cooler problem.
