Abstract
The utility model discloses a gas and sewage recovery device with an outlet of a water-ring vacuum pump, which is applied to gas and sewage recovery of an atmospheric and vacuum distillation device in processing heavy petroleum products. A water sealed tank is connected with a water-ring vacuum pump through a pipeline; an inlet of the water-ring vacuum pump is connected with a gas outlet pipeline at the top of a vacuum distillation tower; an outlet of the water-ring vacuum pump is connected with an inlet at the top of a separating tank through a pipeline; the lower part of the separating tank is provided with an under-tank water sealed pipe; and a gas outlet at the top of the separating tank is connected with an atmospheric-pressure gas inlet furnace pipeline by a pipeline. The under-tank water sealed pipe is internally provided with a suction pipe of a sewage pump; and the end part of the suction pipe of the sewage pump is positioned at the lower part of the suction pipe. An outlet of the sewage pump is connected with a water purification treatment device. The gas and sewage recovery device has the benefits of realizing the gas recovery at the top of the vacuum distillation tower of a distillation device in processing heavy petroleum products, thus improving energy-saving and emission-reducing effects and preventing the gas with hydrogen sulfide exceeding standard at the top of the vacuum distillation tower from being directly discharged into atmosphere, realizing the airtight recovery of sulfur-containing sewage, and further preventing the hydrogen sulfide gas in the sewage from overflowing.
Description
Technical field
The utility model relates to the black petroleum products processing technique field, and the particularly recovery of the coal mine gas of the vacuum pump outlet of atmospheric and vacuum distillation unit depressurized system and sewage is the retrieving arrangement of a kind of coal mine gas and sewage.
Background technology
In the heavy oil upgrading process, it is exactly that pressure is low, flow is little that heavy oil upgrading water distilling apparatus decompression cat head gas has individual common characteristic, causes and reclaims difficulty.And along with oil property worse and worse, it is more and more higher to subtract in the top dehydration hydrogen sulfide content, directly discharging not only influences the effects of energy saving and emission reduction of device, and very easily causes the hydrogen sulfide poisoning accident.Subtract top gas pressure low (only a little more than normal atmosphere), so pipe network can not directly be incorporated into or go into stove fuel; Subtract top gas flow little (per hour less than 1 ton), can't use compressor boost to reclaim.In addition, the vacuum pump outlet sewage of heavy oil upgrading water distilling apparatus decompression cat head gas dehydration enclosed recovery system directly enters trench, can't reclaim.
The utility model content
The purpose of this utility model is: a kind of water-ring vacuum pump outlet gas and device for recycling sewage are provided, realize that airtight recovery subtracts top gas, solve the irretrievable problem of heavy oil upgrading water distilling apparatus decompression cat head gas, prevent to cause environmental pollution and intoxication accident.
The technical solution adopted in the utility model is: water-ring vacuum pump outlet gas and device for recycling sewage, mainly syphon trap, separating tank and sump pump are formed down by water-sealed tank, water-ring vacuum pump, jar, water-sealed tank connects water-ring vacuum pump by pipeline, it is characterized in that: the inlet of water-ring vacuum pump connects decompression cat head gas export pipeline, the outlet of water-ring vacuum pump has pipeline to connect the top inlet of separating tank, in the bottom of separating tank syphon trap under the jar is arranged.There is pipeline to connect normal pressure gas in the outlet of the top of separating tank coal mine gas and goes into furnace line.The tail pipe of sump pump is arranged in the syphon trap under jar, and the end of the tail pipe of sump pump is in the bottom of tail pipe.The sewage pump outlet connects high-efficiency water purifying treatment device.
Syphon trap is cylindrical under described jar, and the height of syphon trap is 4.5 meters under jar.
The beneficial effects of the utility model: the utility model water-ring vacuum pump outlet gas and device for recycling sewage: 1, realized that heavy oil upgrading water distilling apparatus decompression cat head gas reclaims, improve the effects of energy saving and emission reduction of device, that avoids that hydrogen sulfide exceeds standard subtracts top gas discharging directly into atmosphere; 2, realize the airtight recovery of sour water, avoid in the sewage hydrogen sulfide excessive.Eliminated the potential safety hazard that causes employee's hydrogen sulfide poisoning.
