Problems solved by technology

Due to the very high calorific value of heavy oil (low calorific value 38500kJ / kg-44000kJ / kg), the shortcomings of high viscosity and high content of harmful components such as sulfur and alkali have not been overcome.
Harmful components such as alkali and chlorine in the raw materials are relatively high, the preheater system is severely crusted, and the preheater is often blocked, which seriously affects the safe operation of the preheater system. Security risks, etc.

Embodiment Construction

[0026] The patent will be further described below in conjunction with specific embodiments.

[0027] The heavy oil calcined cement production process includes the following steps:

[0028] a. The heavy oil at the ambient temperature of the heavy oil tank is sent from the heavy oil tank to the heat exchanger through the oil filter and the heavy oil supply pump;

[0029] b. The heavy oil is first heated to about 130 degrees. The medium for heating the heavy oil in the heat exchanger is high-temperature heat exchange oil. The high-temperature resistant oil is heated to 260 degrees in the boiler and then sent to the heat exchanger. High temperature oil has been accompanied by heavy oil;

[0030] c. After the heavy oil is pressurized, the pressure is adjusted to 3.5~4.0MPa through the automatic control circuit. After obtaining the temperature and pressure, the heavy oil enters the burner in two ways. The two ways are swirl oil and axial flow oil respectively. Circumferentially di...

Abstract

The invention designs equipment and a process of calcined cement, and specifically relates to a production process and system equipment of heavy oil calcined cement. The production process of heavy oil calcined cement comprises the following steps: heating heavy oil; pressurizing; combusting in paths; and the like. The system equipment of heavy oil calcined cement consists of a heavy oil tank, a diesel tank, a heavy oil replenishment pump, a heat exchanger, a combustion pump, a pressure regulating valve and a combustor. The process and system equipment have the advantages of stabilizing flame and prolonging the service life of the combustor.

Description

[0001] technical field [0002] This patent designs the equipment and process of calcined cement, specifically a heavy oil calcined cement production process and system equipment. [0003] Background technique [0004] In the past 150 years, humans have mainly consumed light oil with an API greater than 32 degrees and medium crude oil with an API between 20 and 32. The ultimate recoverable reserves of conventional crude oil are about 246.6 billion tons, nearly 45% of which have been mined. The era of natural gas will usher in after the end of the oil era, but according to general forecasts, even in the peak period of gas production around 2020, the gas production will reach 3.4 trillion cubic meters per year, which still cannot meet the demand. Therefore, heavy oil should be developed to fill the energy gap. The resources of heavy oil in the world are huge. The original geological reserves of heavy oil are about 863 billion tons. If the recovery rate is 15%, the recoverab...
