Quick-discharging and heating device for vehicle-mounted oil tank

Abstract

The invention relates to a quick-discharging and heating device for a vehicle-mounted oil tank, which comprises a heat exchanger, wherein the cold medium inlet of the heat exchanger is connected with the oil outlet of an oil tank through an output pipe and a pump body, the cold medium outlet of the heat exchanger is connected with the inlet of a three-way valve, one outlet of the three-way valve is connected with an oil inlet of the oil tank through an input pipe, and the other outlet of the three-way valve is connected with an oil exit pipe. The input pipe is a rotary oil filling riser. The lower end of the rotary oil filling riser is connected with a telescopic pipe. The heat exchanger is a vortex hot film heat exchanger. The pump body is an air piston pump. The vehicle-mounted oil tank is connected with the heat exchanger from the outside, and the pump forces the oil to flow through the heat exchanger to be heated to reduce the viscosity of the oil. The quick-discharging and heating device has the advantages of high heat exchange efficiency, quick viscosity reduction, short heating period, direct oil discharge, short tank car occupation period, high rate of turnover, low transport cost, and no post treatment.

Description

(1) Technical field [0001] The invention relates to a heating device for quickly discharging a vehicle-mounted oil tank, which can quickly discharge a high-viscosity liquid transported by the vehicle-mounted oil tank, is environmentally friendly and energy-saving, and belongs to the field of thermal energy devices. (2) Background technology [0002] Because crude oil or heavy oil has high viscosity and poor fluidity at room temperature, when the oil enters and exits the vehicle-mounted oil tank, it needs to be heated to reduce its viscosity and improve fluidity, so a heating device must be installed on the vehicle-mounted oil tank. At present, the heating device generally adopts a heating jacket installed on the lower part of the tank body, and steam is passed into the heating jacket to indirectly heat the oil. The above-mentioned heating device has the following problems: due to the restriction of the tank structure and transportation conditions (environmental temperature),...

AI Technical Summary

Problems solved by technology

The above-mentioned heating device has the following problems: due to the restriction of the tank structure and transportation conditions (environmental temperature), especially in winter, the initial viscosity of the liquid is very high, even if the jacket is heated by steam, it is difficult for the liquid itself to form in a short time. Convection, heat transfer is mainly based on liquid conduction heat transfer, which leads to low heat transfer efficiency, slow viscosity reduction, long heating time, long tanker occupation time, low turnover rate, and high transportation costs; using this heating method condensate discharge temperature High, often accompanied by a large amount of steam discharge, resulting in a waste of energy; the oil that is close to the lower tank wall is heated for too long, which will easily cause overheating and decomposition, reduce the quality, and increase the cost of subsequent treatment
