Problems solved by technology

[0005] At present, the treatment method of this part of waste liquid is to incinerate high-concentration, low-viscosity, relatively single organic waste liquid as the fuel of the incinerator. There has been no reliable and general-purpose method for multi-component, low-viscosity organic mixed waste liquid. Technical route
Cause a serious backlog of this part of organic mixed waste liquid, or illegal discharge
[0006] At the same time, because the generation time and quantity of this waste liquid are mostly temporary, the establishment of a separate incineration device is idle most of the time, resulting in a waste of funds

Embodiment Construction

[0017] Refer to the following figure 1 Examples of the present invention will be described.

[0018] With reference to the accompanying drawings, the detailed steps of the incineration method of the low-viscosity organic mixed waste liquid of the present invention are as follows:

[0019] A method for incinerating low-viscosity organic mixed waste liquid, comprising the following steps:

[0020] A) The external low-viscosity organic mixed waste liquid is injected into the waste liquid storage tank with a pneumatic diaphragm pump, and the external steam heat source is used to control the temperature of the waste liquid in the waste liquid storage tank to 30-40°C to ensure that the waste liquid is in a flowable state ; The temperature of the waste liquid in the waste liquid storage tank and the flow rate of the external steam heat source are controlled in chain to ensure the accuracy of the control.

[0021] B) The waste liquid in the waste liquid storage tank is transported t...

Abstract

The invention discloses a method for incinerating low-viscosity organic mixed waste liquid. The method comprises the following steps of: injecting an external low-viscosity organic mixed waste liquid into a waste liquid storage tank by using a pneumatic diaphragm pump; controlling the temperature of the waste liquid in the waste liquid storage tank to be30-40 DEG C by using an external steam heat source to guarantee that the waste liquid is in a flowable state; conveying the waste liquid in the waste liquid storage tank to a double-fluid waste liquid combustor through a centrifugal pump, wherein a waste liquid return conduit is arranged between the centrifugal pump and the double-fluid waste liquid combustor and is connected to the waste liquid storage tank; controlling the waste liquid supply pressure to be 0.1-0.4MPa by controlling the reflux quantity of the waste liquid; and before the waste liquid enters the double-fluid waste liquid combustor, introducing compressed air into the waste liquid to guarantee that the waste liquid is atomized, and adjusting the proportioning of the waste liquid to the compressed air through a proportional expression to guarantee that the waste liquid is completely atomized.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment. Specifically, the invention relates to an incineration treatment method for low-viscosity organic mixed waste liquid produced in chemical, petroleum and pharmaceutical industries. Background technique [0002] With the increasingly stringent environmental protection, the legal and compliant treatment and disposal of hazardous waste (organic waste liquid) generated in the chemical, petroleum, and pharmaceutical industries has become a difficult problem. [0003] Due to the relatively strict control of process parameters in the petroleum, chemical, and pharmaceutical industries, the types of organic waste liquids generated, the quantity and the time of generation are uncertain, and even low-concentration organic waste liquids generated by cleaning towers and kettles are collectively referred to in the factory as For organic waste. Although the density, composition, concentration,...
