Description
Technical field
The utility model relates to waste oil recovery technology field, is specifically related to a kind of waste oil petrol storage tank negative pressure fireproof tempering device.
Background technology
Along with the development of science and technology, waste mineral oil regeneration recovery technology is increasingly mature, and energy-conserving and environment-protective, are advocated energetically; In waste mineral oil removal process, waste oil petrol storage tank top can produce some light gas, if discharge not in time, in tank pressure cross conference cause blast, in order to avoid causing atmospheric contamination, the light gas after-flame that can will discharge, in this process once there is tempering, fire burns back waste oil petrol storage tank along pipeline, the safety misadventure such as will to blast.
Summary of the invention
For prior art Problems existing, the utility model provides a kind of structure simple, and easy to operate, cost is low, and safety is high, during the light gas burning that waste oil petrol storage tank produces, effectively can prevent the waste oil petrol storage tank negative pressure fireproof tempering device of tempering.
For achieving the above object, the technical solution that the utility model adopts is: waste oil petrol storage tank negative pressure fireproof tempering device, comprises waste oil petrol storage tank, air suctiton ventilator, one-level water seal, secondary water seal, gasification furnace; Waste oil petrol storage tank top is provided with air extractor duct, and one-level water seal and secondary water seal are built with water, and top is all provided with admission port and air extractor duct; The air extractor duct of waste oil petrol storage tank connects the air suctiton inlet of air suctiton ventilator by pipeline, the exhausr port of air suctiton ventilator connects the admission port of one-level water seal by pipeline, the air extractor duct of one-level water seal connects the admission port of secondary water seal by pipeline, the air extractor duct of secondary water seal accesses gasification furnace by pipeline.
Wherein, the water level in described one-level water seal and secondary water seal is lower than its admission port and air extractor duct.
Wherein, the pipeline of the water seal of described access one-level and secondary water seal admission port reaches the bottom.
During work, start air suctiton ventilator, make to keep negative pressure state in waste oil petrol storage tank, the light gas at waste oil petrol storage tank top is discharged from its air extractor duct, under the effect of air suctiton ventilator, light gas through one-level water seal and secondary water seal, is finally admitted to gasification furnace after-flame along pipeline, once there is tempering in the process of light gas burning, fire burns to secondary water seal along pipeline, because the pipeline of secondary water seal admission port has reached the bottom, burned fire is broken by its built-in water resistance, thus effectively prevents tempering.
the utility model has following beneficial effect:
1. the utility model structure is simple, easy to operate, under the effect of air suctiton ventilator, makes waste oil petrol storage tank inside keep negative pressure state, is discharged by the light gas at its top, and be not easy to produce return-air;
2. the light gas at waste oil petrol storage tank top is discharged by the utility model in time, prevent excessive the causing of pressure in tank from exploding, the light gas of discharge sends into gasification furnace after-flame, while avoiding causing atmospheric contamination in gas discharging to air, provide combustion gas to gasification furnace, realize energy-conserving and environment-protective;
3. the pipeline of the utility model access one-level water seal and secondary water seal admission port reaches the bottom, fire from its air extractor duct is burned is broken by built-in water resistance, can not flash back along the pipeline of admission port, effectively prevent tempering, thus the safety misadventures such as the blast avoiding tempering to cause;
4. the utility model is provided with two-stage water seal, once one of them water seal was lost efficacy, another water seal also can block in time flashed back, and effectively improves the safety of this device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-waste oil petrol storage tank, 2-air suctiton ventilator, the water seal of 3-one-level, the water seal of 4-secondary, 5-gasification furnace.
Detailed description of the invention
embodiment:waste oil petrol storage tank negative pressure fireproof tempering device, comprises waste oil petrol storage tank 1, air suctiton ventilator 2, one-level water seal 3, secondary water seal 4, gasification furnace 5; Waste oil petrol storage tank 1 top is provided with air extractor duct, and one-level water seal 3 and secondary water seal 4 are built with water, and top is all provided with admission port and air extractor duct, and the water level in described one-level water seal 3 and secondary water seal 4 is lower than its admission port and air extractor duct; The air extractor duct of waste oil petrol storage tank 1 connects the air suctiton inlet of air suctiton ventilator 2 by pipeline, the exhausr port of air suctiton ventilator 2 connects the admission port of one-level water seal 3 by pipeline, the air extractor duct of one-level water seal 3 connects the admission port of secondary water seal 4 by pipeline, the air extractor duct of secondary water seal 4 is by pipeline access gasification furnace 5, and the pipeline of described access one-level water seal 3 and secondary water seal 4 admission port reaches the bottom.
During work, start air suctiton ventilator 2, make to keep negative pressure state in waste oil petrol storage tank 1, the light gas at waste oil petrol storage tank 1 top is discharged from its air extractor duct, under the effect of air suctiton ventilator 2, light gas along pipeline through one-level water seal 3 and secondary water seal 4, finally be admitted to gasification furnace 5 after-flame, once there is tempering in the process of light gas burning, fire burns to secondary water seal 4 along pipeline, because the pipeline of secondary water seal 4 admission port has reached the bottom, burned fire is broken by its built-in water resistance, thus effectively prevents tempering.
