Sludge mixed burning system

Abstract

The invention relates to the field of sludge treatment, and particularly relates to a sludge mixed burning system. The sludge is stored in a sludge silo, a feeder drives the sludge to enter a sludge crusher so that the sludge is processed into pieces or powders capable of being blown by high pressure gas, weighing is conducted on the sludge by using a weighing silo so that the amount of the sludgeguided into a boiler furnace is controlled conveniently, and the power generation efficiency of a power plant is improved; and a first air intake valve can lead the high-pressure gas of the gas source to the weighing silo so that the sludge in the weighing silo is blown to a conveying silo, and a second air intake valve can lead the high-pressure gas of the gas source to the conveying silo, so that the sludge in the conveying silo is blown to the discharging end of the conveying silo, and the sludge is conveyed to the boiler furnace through a conveying pipe. According to the sludge mixed burning system, the contacting time of the sludge with the outside air and moisture coal can be reduced to the utmost extent, so that hardening of the sludge due to moisture absorbing is avoided, the factthat the odor of the sludge pollutes the outside air can be further avoided, and humidity manual controlling of the air source can be easier conducted.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge blending combustion system. Background technique [0002] According to its source, sludge can be roughly divided into: municipal sludge, pipe network sludge, river and lake sludge and industrial sludge. In addition, some processes also produce by-products similar to sludge. [0003] Municipal sludge is the largest type of sludge, mainly from sewage treatment plants and waterworks. As of the end of June 2018, more than 5,000 sewage treatment plants have been built in cities and towns across the country, the sewage treatment capacity has reached 190 million cubic meters per day, and the associated sludge has exceeded 50 million tons per year (calculated with a moisture content of 80%). With the rapid development of my country's national economy and the improvement of urbanization level, the amount of sewage discharge and associated sludge will increase year by year. [0...
