Embodiment 1

[0036] refer to figure 1 , an organic waste liquid gasification furnace, comprising a furnace body 100 and a gasification chamber 110 inside the furnace body 100, the furnace body 100 is provided with an air inlet channel 120 and an air outlet channel communicating with the gasification chamber 110 150, the outer side of the furnace body 100 is provided with a waste liquid storage tank 200 for storing waste liquid, and the waste liquid storage tank 200 is connected with the waste liquid outlet at the bottom of the gasification chamber 110, and a mist atomization nozzle 130, the atomization nozzle 130 atomizes the waste liquid in the waste liquid storage tank 200 and then sprays it into the furnace body 100; The organic volatiles and the hot air are blown out from the outlet channel 150 along with the organic volatiles, and the incompletely vaporized waste liquid flows back into the waste liquid storage tank 200 .

[0037]The hot air can evaporate the volatile matter in the or...

Embodiment 2

[0049] This embodiment proposes a method for reducing hot air consumption during the process of hot air blowing out from the air outlet channel 150. Specifically, the bottom surface of the gasification chamber 110 is a conical surface, and the air outlet channel 150 and the air inlet channel 120 set in the vertical direction.

[0050] When the volatile matter driven by the hot air flows in the vertical air inlet passage 120, the contact area with the inner wall of the passage is small, and the volatile matter is not easy to adhere to the pipe wall, and the hot air is sprayed vertically downward from the air inlet passage 120 to the gasification In the chamber 110, it flows along the conical bottom surface of the gasification chamber 110. If the bottom surface is a plane, the hot air blowing on the plane will have a greater reaction force, and the hot air will disperse to both sides, while the conical bottom surface can guide The flow of hot air, the hot air entering from the a...

Embodiment 3

[0053] This embodiment proposes a method for controlling the volatile matter concentration and temperature in the air outlet channel 150: refer to Figure 5 The inner wall of the air outlet channel 150 is provided with a VOC concentration monitor 180 for detecting the concentration of volatile components and a thermocouple 190 for detecting the temperature, and the air intake volume of the hot air is adjusted according to the detected temperature and concentration. The flow rate of hot air blown into the gasification chamber 110 is controlled by the hot air regulating valve. When the VOC concentration detected by the VOC concentration monitor 180 is low, the system automatically opens the hot air regulating valve to increase the air volume of the hot air intake, thereby improving the gasification rate. The temperature in the chamber 110 increases the vaporization rate of volatile matter; similarly, when the VOC concentration detected by the VOC concentration monitor 180 is too ...

Abstract

The invention discloses an organic waste liquid gasification furnace and a waste gas treatment process, belongs to the field of industrial waste gas treatment, avoids the situations of scaling and blockage of a nozzle during incineration, and solves the problem of corrosion of waste liquid to equipment. The organic waste liquid gasification furnace comprises a furnace body and a gasification chamber in the furnace body, wherein an air inlet channel and an air outlet channel which communicate with the gasification chamber are arranged in the furnace body; a waste liquid storage tank for storingthe waste liquid is arranged on the outer side of the furnace body and communicates with a waste liquid outlet at the bottom of the gasification chamber; an atomizing nozzle is arranged in the furnace body and used for atomizing the waste liquid in the waste liquid storage tank and then spraying the atomized waste liquid into the furnace body; and hot air is introduced into the air inlet channelto evaporate organic volatiles in the waste liquid mist, then the hot air is blown out of the air outlet channel along with the organic volatiles, and the incompletely gasified waste liquid flows backinto the waste liquid storage tank. The organic waste liquid gasification furnace and the waste gas treatment process can be applied to products of waste liquid treatment devices and the like.

Description

【Technical field】 [0001] The invention relates to the field of industrial waste gas treatment, in particular to an organic waste liquid gasifier and a waste gas treatment process. 【Background technique】 [0002] The chemical and pharmaceutical industry and industrial container cleaning industry will produce high-concentration organic waste liquid, which has the characteristics of complex composition, high viscosity, and certain corrosiveness. It is difficult to meet the standard by using general chemical methods, and the method of direct incineration often encounters the problems of nozzle fouling, serious corrosion, and high energy consumption. The composition of organic waste liquid is complex, and it contains a large amount of components that can be burned to generate carbon dioxide and water. Separating the volatile components in the waste liquid before burning can avoid the problem of nozzle fouling and blockage. 【Content of invention】 [0003] The technical problem ...
