Embodiment 1

[0022] An embodiment provided by the present invention: a hazardous waste kiln collaborative treatment process, crushing process:

[0023] The multi-blade grab lifts the solid and semi-solid hazardous waste to the collecting hopper of the hydraulic rotary shearing crusher, and the solid and semi-solid hazardous waste is sheared, torn and squeezed by the hydraulic rotary shearing crusher; Reduce the material size to meet the crushing requirements. The hydraulic rotary shear crusher is driven by hydraulic pressure, and the two drive shafts of the hydraulic rotary shear crusher are equipped with a hydraulic motor and a reducer respectively. Industrial and hazardous waste, and their packaging: such as iron or lead drums, plastic drums, glass jars and ceramic containers, can be directly put into the hydraulic rotary shear crusher and crushed.

[0024] The hydraulic rotary shear crusher is equipped with a hydraulic pusher and an automatic discharge door. When the hydraulic rotary s...

Embodiment 2

[0026] An embodiment provided by the present invention: a hazardous waste kiln collaborative treatment process, mixing process:

[0027] Hazardous waste crushed by the hydraulic rotary shear crusher has a maximum particle size of 250mmX60mm. The hazardous waste crushed to a suitable size falls from the closed chute into the horizontal hydraulic mixer below due to gravity. At the same time, industrial toxic Harmful and dangerous waste, waste oil, sludge, waste organic volume and waste water also enter the horizontal hydraulic mixer through the nozzle reserved on the hydraulic rotary shear crusher.

Embodiment 3

[0029] An embodiment provided by the present invention: a hazardous waste kiln collaborative processing process, the transportation process:

[0030]The material prepared by the horizontal hydraulic mixer falls into the hydraulic high-density single-piston solid pump unit under the horizontal hydraulic mixer under the action of gravity, and the material entering the hydraulic high-density single-piston solid pump unit is first pumped by a horizontally installed hydraulic The shaftless screw conveyor pushes above the feed inlet of the single plunger pump of the hydraulic high-density single-piston solid pump unit, and at the end of the hydraulic shaftless screw conveyor is connected with the hydraulic shaftless screw conveyor and the hydraulic high-density single-piston solid pump The single plunger pump of the unit is equipped with a set of forced feeder in the orthogonal and vertical direction. The forced feeder is composed of two hydraulic pistons that reciprocate in the vert...

Abstract

The invention discloses a cooperative treatment process for a hazardous waste kiln. Solid and semi-solid hazardous waste materials are crushed by a hydraulic rotary shear crusher; the waste materials enter a horizontal hydraulic mixer; the materials fall into a hydraulic high-density single-piston solid pump unit below the horizontal hydraulic mixer under the action of gravity, enter a spray gun by virtue of the pumping residual pressure of a single plunger pump of the hydraulic high-density single-piston solid pump unit, and enter an incinerator after being scattered by the spray gun; and waste gas generated through cooperative incineration of the hazardous waste materials by the incinerator enters a waste heat boiler through a tail gas discharge channel, the waste gas is cooled to 800 DEG C for the first time in the waste heat boiler, then the waste gas enters a quench tower, the waste gas is suddenly cooled to 200 DEG C or below within 1 s, and the gas is discharged out of the quench tower to be treated and discharged. The cooperative treatment process has the advantages of no adverse effect on the safety of the surrounding natural ecological environment, replacement and saving of a part of natural fossil, fuel and coal, and reduction of carbon dioxide emission.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a hazardous waste kiln collaborative treatment process. Background technique [0002] According to statistics in 2007, the national hazardous waste generation was 17.6 billion tons, an increase of 15.9% over the previous year, and the discharge volume was 119.67 million tons, a decrease of 66.5% over the previous year. Ton. According to the data in the Environmental Status Bulletin of Guangdong Province, the hazardous waste production in 2006, 2008 and 2009 was 1,101.07 million tons, 1,298.84 million tons, and 1,413,795 tons respectively. Reached 196 million tons. It can be seen from the prediction results that with the continuous growth of the national economic aggregate, the generation of hazardous waste is still showing an increasing trend year by year, and the pressure on comprehensive utilization and subsequent disposal of hazardous waste will also increa...
