Problems solved by technology

[0003] At present, the waste liquid produced in the process of heavy oil catalysis, diesel hydrogenation, liquefied gas desulfurization, gas desulfurization, sewage stripping and other equipment treatment equipment maintenance, glass plate efficiency inspection and pump maintenance in refining and chemical enterprises is difficult to deal with, and most of them enter In the coking pool, the waste lye has a strong odor, and there is no corresponding control measure for the pressure inside, which makes the pressure in the tank relatively high and has great danger. Therefore, it is necessary to design a petroleum waste liquid recovery equipment

Abstract

The invention discloses a petroleum wastewater recycling apparatus, comprising a liquid storage tank that is hinged to electric telescopic columns through hinging fasteners; the electric telescopic columns are fixedly connected with support legs, the electric telescopic columns are electrically connected with a PLC (programmable logic controller), a pressure sensor and a liquid level sensor are arranged in the liquid storage tank, one side of the right side of the top end of the liquid storage tank is provided with a liquid inlet, the other side of the liquid storage tank is provided with a pressure meter, the pressure meter is electrically connected with the pressure sensor, a relief port is provided between the liquid inlet and the pressure meter and is provided with an automatic breather valve, a decompressor is provided below the relief port, two sides of the bottom end of the liquid storage tank are provided with liquid outlets, and an electromagnetic valve is arranged at each liquid outlet. In the invention, the petroleum wastewater recycling apparatus is simple in structure, enables the inner pressure issue of a treatment tank to well solved, and reduces dangers due to high pressure in tank.

Description

technical field [0001] The invention belongs to the technical field of petroleum production, and in particular relates to recovery equipment for petroleum waste liquid. Background technique [0002] Due to the needs of device production, safety and environmental protection, heavy oil catalysis, diesel hydrogenation, liquefied gas sweetening, gas desulfurization, sewage stripping and other devices will produce a small amount of dangerous goods in the process of treatment equipment maintenance, glass plate efficiency inspection and pump maintenance. Waste liquid, in order to prevent dangerous waste liquid from flowing into the ground and causing pollution, a small bucket is used to collect the liquid, and then a small amount of waste liquid is introduced into a large bucket. After waiting for about 2 to 3 months, half of the liquid in the bucket is poured into the coking pool for coking. At the same time, the pool emits a foul smell, polluting the environment, and a small amou...
