Liquid hazardous waste pre-treatment and exhaust gas collection device

Abstract

The invention provides a liquid hazardous waste pre-treatment and exhaust gas collection device. One end of a spray pipe of the device is connected to a reuse reclaimed water storage tank while the other end of the spray pipe is connected to a hazardous liquid waste storage tank, waste liquor in the hazardous liquid waste storage tank is sucked into the spray pipe through a first self-priming pump, reuse reclaimed water in the reuse reclaimed water storage tank is sucked into the spray pipe through a second self-priming pump, a mixing and stirring device is mounted below the spray pipe, a hopper is mounted on one side above the mixing and stirring device, a feeding device is mounted on the hopper side, an unloading device is mounted at the bottom of the mixing and stirring device, a firstvalve is mounted on the unloading device, a seal cover is mounted on the other side above the mixing and stirring device, and a gas collecting pipeline is mounted above the seal cover. The liquid hazardous waste pre-treatment and exhaust gas collection device solves the problem of feeding liquid hazardous wastes treated by way of pump spraying into a rotary kiln to incinerate. The liquid hazardouswaste pre-treatment and exhaust gas collection device which pre-treats the liquid hazardous wastes is safer and more stable by adopting liquid waste neutralizing and stirring equipment and a device of collecting harmful gas generated during stirring, so that the treatment progress of the liquid wastes is improved.

Description

technical field [0001] The invention relates to a liquid hazardous waste pretreatment and exhaust gas collection device, which adopts hazardous waste incineration technology and belongs to the technical field of environmental protection devices. Background technique [0002] The incineration process is one of the effective means for the harmless treatment of hazardous waste. Usually, different types of hazardous waste solids are mixed and stirred, and the solid waste is sent to the incineration rotary kiln for incineration through a grab bucket. However, some liquid hazardous wastes cannot be grabbed by the grab bucket and sent to the rotary kiln for incineration. At this time, a booster pump is needed to spray it into the rotary kiln for incineration through the pipeline pump. However, this method has high requirements on the viscosity of the liquid, high impurity content, and pH when treating liquid waste. Too many impurities and too high viscosity cannot be atomized and s...
