An industrial boiler burning heavy oil impurity removal clarification filter device

Abstract

The invention discloses a filter for removing impurities and clarifying combustion heavy fuel of an industrial boiler. The filter comprises a solid-liquid separator, a separated fuel output pipe, a solid damping cover, a tangential fuel inlet pipe, a separating and settling chamber and a precipitate discharging hole, wherein the solid-liquid separator is arranged at the top end of the interior of the separating and settling chamber; the separated fuel output pipe is arranged in the solid-liquid separator and upwardly extends out of the separating and settling chamber; the solid damping cover is arranged at the lower end of the solid-liquid separator; the tangential fuel inlet pipe is arranged on the outer side of the separating and settling chamber; the precipitate discharging hole is formed in the bottom end of the separating and settling chamber. The filter for removing impurities and clarifying combustion heavy fuel of the industrial boiler can ensure that the filter causes no influence on the combustion of the industrial fuel boiler in the cleaning process, improves the filtration capability, avoids blockage of the impurities in the fuel to instruments and meters and prolongs the service life of a fuel pump.

Description

technical field [0001] The invention relates to a recycling treatment of heavy oil for industrial combustion, in particular to a method and equipment for removing impurities and filtering heavy oil for industrial boiler combustion. It belongs to the field of resource utilization of industrial heavy oil. Background technique [0002] Fuel has played an important role in human life since ancient times. With the advancement of civilization, human beings' demand for fuel, especially oil fuel, has greatly increased. However, the oil resources that provide the main oil fuel for human beings are increasingly depleted, and the prices of various fuel oils are also rising rapidly. For example, in the domestic market of heavy oil in the 1970s, the price per ton of heavy oil was generally around 500 yuan, but now it has risen to more than 2,000 yuan. In order to solve this contradiction, people came up with various measures. Mainly starting from the direction of production substitute...

Problems solved by technology

[0003] Existing industrial oil-fired boilers spray heavy oil into the combustion chamber through oil pumps, flow meters, and oil gun atomizing nozzles to achieve full combustion of heavy oil and provide heat for the heating unit. In order to save costs, industrial heavy oil is mainly made of waste tires at this stage , chemical waste residue, coal tar, coal tar pitch, swill oil and other waste materials, although the cost of fuel use has been further reduced, but it also caused more impurities in the fuel, which often caused the instrumentation, pipelines, and flow meters of industrial oil-fired boilers , Clogging of the nozzle of the oil gun

Adding heavy oil impurity filtering equipment at the front end of the system can avoid the blockage of combustion equipment such as fuel injectors. However, the existing heavy oil filtering equipment often needs to clean the system when it is shut down. The equipment has strict requirements on oil products and insufficient filtering capacity. The impurities on the oil pump are severely worn during filtration. Due to the increase of impurities, the service life of the screw pump is reduced. The entire system is blocked for an average of 2 months and needs to be shut down for cleaning.
