Embodiment Construction

[0010] The present invention will be further described in detail below with reference to the accompanying drawings, see the accompanying drawings.

[0011] A test system for dry distillation and carbonization of municipal sludge. The test system consists of a dry distillation reaction device, a gas-liquid collection device, a gas processing device and a control device. The dry distillation reaction device consists of a first gas control valve 1, a locking button 2, and a reaction vessel cover 3. , Motor 4, barometer 19, heating device 20, reaction kettle 21, stirrer 22, first temperature sensor 23, second temperature sensor 24 and vacuum pump 25. The reaction kettle 21 is in a sandwich shape, and the reaction kettle 21 is set in the sandwich There is a heating device 20 and a heat insulation layer. The heat insulation layer is located between the heating device 20 and the outer interlayer of the reactor 21. The upper part of the wall of the reactor 21 is provided with a first temp...

Abstract

The invention relates to a municipal sludge destructive distillation carbonation test system and belongs to the technical field environment engineering. The test system comprises a destructive distillation reaction device, a gas-liquid collecting device, a gas treatment device and a control device. The municipal sludge destructive distillation carbonation test system has the advantages that a vacuum pump and one-way valve used by the destructive distillation reaction device vacuumize a reaction kettle before the destructive distillation of sludge, the risk of explosion is avoided, and system safety is guaranteed; each of the reaction kettle and a reaction kettle cover adopts a sandwich structure, a thermal-insulation layer is arranged in each sandwich layer, the temperature in the reaction kettle is guaranteed, and heat loss is lowered; a condenser and a cooling-water machine effectively guarantee the condensation separation effect of destructive distillation products; a gas burner guarantees that tail gas can meet standards; the destructive distillation products can be sampled and analyzed at any time, the temperature of each link can be monitored in real time, and destructive distillation parameters can be optimized conveniently; system parameters can be set on the control device, the control device treats data, and system efficiency is increased greatly.

Description

Technical field [0001] The invention relates to a municipal sludge carbonization test system, which belongs to the technical field of environmental engineering. Background technique [0002] With the acceleration of my country's urbanization process, the municipal sewage treatment rate has increased year by year, and the output of municipal sludge has also increased sharply. In 2015, the annual sludge production exceeded 60 million tons, and the average annual growth rate of sludge was greater than 18%. According to statistics, 80% of the national sludge is not properly treated every year. Incidents of sludge being secretly discharged into farmland, rivers, mines and oceans have been repeatedly prohibited. Heavy metals, persistent organic pollutants and volatile organic compounds in the sludge can affect the soil and groundwater. And the atmosphere caused serious pollution, which seriously threatened environmental safety. [0003] Municipal sludge contains combustible substances, ...
