Oil sludge pyrolysis single-cylinder two-barrel plunger pump continuous feeding device and method

Abstract

The invention relates to a continuous feed device and method for a single-cylinder two-barrel plunger pump for oil sludge pyrolysis. The device includes a storage bin with a feed inlet and a discharge outlet; The feed port is connected, and the outlet is connected with the oil sludge feed main pipe; the first reversing valve is connected to the oil sludge feed main pipe and the two sides are respectively connected with the first and second feed pipes; the first and second feed pipes connected by connecting rods One-way plunger pump, the pump chamber of the first one-way plunger pump communicates with the first feed pipe and the first discharge pipe, and the pump chamber of the second one-way plunger pump communicates with the second feed pipe and the second discharge pipe. The feed pipes are connected, and the working states of the two feed and discharge materials are opposite; the two sides of the second reversing valve are respectively connected with the first and second discharge pipes and connected with the oil sludge discharge main pipe. The method is realized by the above-mentioned device. Through the device and method of the present invention, one-way and continuous transportation of high-viscosity oil sludge can be realized, while anaerobic, high-pressure long-distance transportation can be ensured, providing guarantee for subsequent pyrolysis treatment of oil sludge.

Description

technical field [0001] The invention belongs to the technical field of environment, energy and environmental protection, and more specifically relates to a continuous feeding device and method of a single-cylinder, two-barrel plunger pump for oil sludge pyrolysis. Background technique [0002] The annual output of oily sludge in my country is huge, and there are three main ways of generation: from the extraction process of crude oil, the production and transportation process of crude oil, and oil refineries and sewage treatment plants. Among them, in the process of crude oil extraction, the oil sludge output is 0.5% to 1% of the crude oil output. According to the figures from the National Bureau of Statistics, the total crude oil extraction in my country in 2014 was 2.1×10 8 tons, and the output of oil sludge is about 2 million tons, and since many oil fields in my country have entered the end of exploitation, the proportion of oil sludge will be even greater. The oil conte...

Problems solved by technology

[0003] The process of producing oil, gas and charcoal by anaerobic pyrolysis of oily sludge has its advanced nature, so that all the organic matter in the sludge can be treated, the oil can be recovered, and the final disposal of harmless and resourceful can be realized. However, in the actual production process, due to Oil sludge has high viscosity and poor fluidity, and the feeding system of ordinary garbage or municipal sludge cannot transport oil sludge. Therefore, a conveying system that can realize continuous feeding and ensure a closed and anaerobic feeding process needs to be developed urgently
