Abstract
The utility model provides preparing propylene from methanol device fuel gas pipe network pressure balancing system, its technological scheme: surge tank (4) is provided with pressure gauge (3), surge tank (4) connects dry gas aromatisation device (5) respectively by transfer line (17), stablize tower top knock out drum (6), gas divides depropanization return tank of top of the tower (7), deethanization return tank of top of the tower (8), propylene rectification tower top return tank (9), surge tank (4) also connects lpg spherical tank A(1 respectively by compensation pipes (12)), lpg spherical tank B(2), propane spherical tank A(10), propane spherical tank B(11), surge tank (4) connects heat-conducting oil furnace (14) respectively by burning line (13), aromatisation oven (15) and oven (16).The utility model fires surge tank voltage stabilizing by gas compensation, fuel gas pressure balance, thus ensures gas ductwork pressure, and then ensures that the burning of use gas oven and heat-conducting oil furnace is steady, and assurance device fortune is steady.
Description
Technical field
The utility model relates to methyl alcohol technical field, especially preparing propylene from methanol device fuel gas pipe network pressure balancing system.
Background technique
Former gas ductwork arranged outward by dry gas aromatisation device poor alkene dry gas, stablize that tower top knock out drum arranges fixed gas irregularly outward, gas divide depropanization return tank of top of the tower irregularly outer arrange fixed gas, deethanization return tank of top of the tower irregularly outer arrange fixed gas, propylene rectification tower top return tank irregularly outer row's fixed gas form, gas ductwork pressure steadily affect device and operates.Being communicated with spherical tank by gas ductwork keeps gas ductwork pressure steady.
Summary of the invention
The utility model provide band compensation voltage stabilizing preparing propylene from methanol device fuel gas pipe network pressure balancing system, its technological scheme: primarily of lpg spherical tank A, lpg spherical tank B, pressure gauge, surge tank, dry gas aromatisation device, stablize tower top knock out drum, gas divides depropanization return tank of top of the tower, deethanization return tank of top of the tower, propylene rectification tower top return tank, propane spherical tank A, propane spherical tank B, compensation pipes, burning line, heat-conducting oil furnace, aromatisation oven, oven and transfer line formation; Surge tank is provided with pressure gauge, surge tank connects dry gas aromatisation device respectively by transfer line, stablizes tower top knock out drum, gas divides depropanization return tank of top of the tower, deethanization return tank of top of the tower, propylene rectification tower top return tank, surge tank also connects lpg spherical tank A, lpg spherical tank B, propane spherical tank A, propane spherical tank B respectively by compensation pipes, and surge tank connects heat-conducting oil furnace, aromatisation oven and oven respectively by burning line.
The utility model fires surge tank voltage stabilizing by gas compensation, fuel gas pressure balance, thus ensures gas ductwork pressure, and then ensures that the burning of use gas oven and heat-conducting oil furnace is steady, and assurance device fortune is steady.
Accompanying drawing explanation
Fig. 1 is this real new structure schematic diagram.
Embodiment
As shown in Figure 1, preparing propylene from methanol device fuel gas pipe network pressure balancing system, its primarily of lpg spherical tank A1, lpg spherical tank B2, pressure gauge 3, surge tank 4, dry gas aromatisation device 5, stablize tower top knock out drum 6, gas divides depropanization return tank of top of the tower 7, deethanization return tank of top of the tower 8, propylene rectification tower top return tank 9, propane spherical tank A10, propane spherical tank B11, compensation pipes 12, burning line 13, heat-conducting oil furnace 14, aromatisation oven 15, oven 16 and transfer line 17 are formed; Surge tank 4 is provided with pressure gauge 3, surge tank 4 connects dry gas aromatisation device 5 respectively by transfer line 17, stablizes tower top knock out drum 6, gas divides depropanization return tank of top of the tower 7, deethanization return tank of top of the tower 8, propylene rectification tower top return tank 9, surge tank 4 also connects lpg spherical tank A1, lpg spherical tank B2, propane spherical tank A10, propane spherical tank B11 respectively by compensation pipes 12, and surge tank 4 connects heat-conducting oil furnace 14, aromatisation oven 15 and oven 16 respectively by burning line 13.
The utility model technological process: by the poor alkene dry gas of the outer row of dry gas aromatisation device 5, stablize tower top knock out drum 6, gas divides depropanization return tank of top of the tower 7, deethanization return tank of top of the tower 8, propylene rectification tower top return tank 9 four tank is irregularly outer arranges fixed gas, gas ductwork pressure is not steady, again by lpg spherical tank A1, lpg spherical tank B2, propane spherical tank A10, propane spherical tank B11 tetra-tank compensates, surge tank 4 carries the fuel gas of voltage stabilizing, thus ensure gas ductwork pressure, and then guarantee gas, heat-conducting oil furnace 14, the burning of aromatisation oven 15 and oven 16 is steady, assurance device fortune steadily.
