Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical equipment, in particular to a condensed water recovery device for a methanol deaerator. Background Art
[0002] In the actual chemical production process of methanol produced from coke oven gas, the deaerator station is used as an independent water supply station for boilers and other equipment and pipelines with high water quality requirements. Most methanol plant deaerator stations are designed as thermal deaerator stations.
[0003] The existing thermal deoxidation is deoxidized by a thermal deaerator, which includes a deoxidation head and a water storage tank. The deoxidation head is provided with an exhaust steam discharge port and a feed water inlet. When in use, the feed water is heated by the heating steam in the deoxidation head. As the feed water temperature rises, the oxygen and other non-condensable gases dissolved in it escape from the water and are discharged together with the steam in the form of exhaust steam through the exhaust steam discharge port. The exhaust steam includes oxygen, other non-condensable gases and water vapor, among which water vapor accounts for the largest proportion.
[0004] However, when the thermal deaerator discharges non-condensable gases such as oxygen, water vapor is also discharged and wasted. In addition, since our feed water is desalted water, the water treatment cost is high and the energy consumption is large. In today's increasingly scarce energy, the thermal deaerator must eliminate the waste of water vapor and heat while removing oxygen. This is an urgent problem that the thermal deaerator needs to solve. Utility Model Content
[0005] In order to overcome the shortcomings and defects of resource waste and high cost in the prior art, the utility model provides a methanol deaerator condensate recovery device with a simple structure, which can completely recover water vapor in exhaust steam, greatly save desalted water, and reduce production costs and energy consumption.
[0006] The utility model adopts the following technical scheme to solve the technical problem: a methanol deaerator condensate recovery device, comprising a thermal deaerator, a deaerator drain valve is arranged on the top of the thermal deaerator, a heat exchanger is arranged on the right side of the thermal deaerator, the deaerator drain valve is connected to one end of the heat exchanger through a pipeline, a recovery device is arranged on the right side of the heat exchanger, the other end of the heat exchanger is connected to the upper part of the recovery device through a pipeline, a circulating water pump is arranged on the right side of the recovery device, the water inlet end of the circulating water pump is connected to the lower part of the recovery device through a pipeline, and the water outlet end of the circulating water pump is connected to the water supply port of the thermal deaerator through a circulating pipeline.
[0007] As a further improvement of the present invention, the thermal deaerator, the heat exchanger, the recovery device and the circulating water pump are all made of 304 stainless steel.
[0008] As a further improvement of the present invention, the suspended film deaerator wire mesh inside the thermal deaerator is made of 304 stainless steel.
[0009] As a further improvement of the utility model, the heat exchanger is provided with heat exchange tubes made of 304 stainless steel, multi-layer baffles and heat exchange tube fins.
[0010] As a further improvement of the utility model, an observable liquid level gauge and a thermometer are provided on the recovery device.
[0011] As a further improvement of the utility model, the circulating water pump adopts a high-energy-efficiency multi-stage pump.
[0012] Compared with the prior art, the utility model has the beneficial effects: in this scheme, a deaerator drain valve is provided on the top of the thermal deaerator. First, after the deaerator drain valve is opened, the thermal deaerator is connected to the heat exchanger, and the recovered steam enters the heat exchanger, enters the recovery device after heat exchange, and the circulating water pump is connected to the recovery device for controllable recycling, so that the water vapor in the exhaust steam of the deaerator can be completely recovered, which greatly saves desalted water, reduces production costs and energy consumption, and all condensed water enters the deaerator system for recycling.
