Abstract
The utility model relates to a reaction tail gas excess heat recovery device for an ether decomposer reactor, belonging to the field of chemical equipment. The reaction tail gas excess heat recovery device is characterized by comprising a heat exchanger, a methyl tert-butyl ether (MTBE) pretreating column, an absorption column and an ether decomposer reactor, wherein the MTBE pretreating column is connected with a tube pass of the heat exchanger through a duct; and the ether decomposer reactor and the absorption column are respectively connected with an inlet and an outlet of a shell pass of the heat exchanger through ducts. Since the heat exchanger is additionally arranged, high-temperature tail gases of the MTBE pretreating column and the reactor, which are fluids with different temperatures, exchange heat at the additionally arranged heat exchanger. The additionally arranged heat exchanger exchanges heat (excess) in the tail gas of the reactor to the charge-in material of the MTBE pretreating column, thereby reducing the consumption of cooling water in the subsequent procedures, reducing the consumption of steam of the MTBE pretreating column and further reducing the consumption of energy sources.
Description
Technical field
The utility model relates to a kind of ether and separates device reaction device reaction end gas waste-heat recovery device, belongs to the chemical industry equipment field.
Background technology
In existing technology, methyl tertiary butyl ether(MTBE) pretreater feeding temperature is lower, and this tower steam consumption is higher; To advance the temperature on absorption tower too high and ether is separated device reaction device tail gas, and the operation easier of this tower is bigger, and the consumption of cooling circulating water is very big, has caused unnecessary energy resource consumption.
Summary of the invention
According to the deficiency of prior art, the technical problem that the utility model will solve is: provide a kind of ether to separate device reaction device reaction end gas waste-heat recovery device, reduce production costs, fully reclaim heat energy, reduce energy loss.
The utility model solves the technical scheme that its technical problem adopted: provide a kind of ether to separate device reaction device reaction end gas waste-heat recovery device; It is characterized in that comprising: heat exchanger, methyl tertiary butyl ether(MTBE) pretreater, absorption tower and ether are separated the device reaction device; The methyl tertiary butyl ether(MTBE) pretreater connects the tube side of heat exchanger through pipeline, and ether is separated device reaction device and absorption tower are connected heat exchanger shell pass respectively through pipeline import and export.
Ether is separated device reaction device tail gas and is walked the heat exchanger tube side, and the methyl tertiary butyl ether(MTBE) charging is through the laggard methyl tertiary butyl ether(MTBE) of heat exchanger shell pass heat exchange (MTBE) pretreater.Methyl tertiary butyl ether(MTBE) pretreater and ether are separated two kinds of fluid at differing temperatures of device reaction device high-temperature tail gas and are added heat exchange in the heat exchanger newly.Heat exchanger is separated the heat (unnecessary) in the device reaction device tail gas with ether; Exchange to the charging of methyl tertiary butyl ether(MTBE) pretreater through exchanger heat; Both reduced subsequent handling cooling water amount; Reduce the steam use amount of methyl tertiary butyl ether(MTBE) pretreater again, thereby reduced the consumption of the energy.
The beneficial effect of the utility model is: through installing additional of heat exchanger, two kinds of fluid at differing temperatures of MTBE pretreater and reactor high temperature tail gas are newly adding the heat exchange of heat exchanger.Newly add heat exchanger with the heat in the reactor tail gas (unnecessary); Exchange to the charging of MTBE pretreater through exchanger heat; Both reduced subsequent handling cooling water amount, reduced the steam use amount of MTBE pretreater again, thereby reduced the consumption of the energy.
Description of drawings
Fig. 1 is the structural representation of the utility model;
1 is heat exchanger among the figure; 2 is the methyl tertiary butyl ether(MTBE) pretreater; 3 is the absorption tower; 4 separate the device reaction device for ether.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; The utility model comprises: heat exchanger 1, methyl tertiary butyl ether(MTBE) pretreater 2, absorption tower 3 and ether are separated device reaction device 4; Methyl tertiary butyl ether(MTBE) pretreater 2 connects the tube side of heat exchanger 1 through pipeline, and ether is separated device reaction device 4 and absorption tower 3 are connected heat exchanger 1 shell side respectively through pipeline import and export.
Ether is separated device reaction device 4 tail gas and is walked heat exchanger 1 tube side, and the methyl tertiary butyl ether(MTBE) charging is through the heat exchanger laggard methyl tertiary butyl ether(MTBE) of 1 shell side heat exchange (MTBE) pretreater 2.Methyl tertiary butyl ether(MTBE) pretreater 2 is separated two kinds of fluid at differing temperatures of device reaction device 4 high-temperature tail gas with ether and is added 1 li heat exchange of heat exchanger newly.Heat exchanger 1 is separated the heat (unnecessary) in device reaction device 4 tail gas with ether, through the charging that methyl tertiary butyl ether(MTBE) pretreater 2 has been given in heat exchanger 1 heat exchange, both reduced subsequent handling cooling water amount; Reduced the steam use amount of methyl tertiary butyl ether(MTBE) pretreater 2 again; Thereby reduced the consumption of the energy, and the high-temperature tail gas through heat exchanger 1 shell side through heat exchange after, the temperature reduction; And then get into absorption tower 3, practiced thrift the recirculated water consumption on absorption tower 3.
