Example Embodiment

[0035] Example one:

[0036] Reference figure 1 , The organic waste liquid gasification furnace includes a furnace body 100 and a gasification chamber 110 in 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. A waste liquid storage tank 200 for storing waste liquid is provided on the outside of the furnace body 100, the waste liquid storage tank 200 is in communication with the waste liquid outlet at the bottom of the gasification chamber 110, and the furnace body 100 is provided with mist The atomizing nozzle 130 atomizes the waste liquid in the waste liquid storage tank 200 and sprays it into the furnace body 100. The air inlet channel 120 passes through the hot air to evaporate the waste liquid mist. For organic volatiles, hot air is blown out from the air outlet channel 150 along with the organic volatiles, and the incompletely vaporized waste liquid flows back int...

Example Embodiment

[0048] Embodiment two:

[0049] This embodiment proposes a method for reducing hot air consumption during the process of blowing hot air from the air outlet channel 150. Specifically, the bottom surface of the gasification chamber 110 is a tapered 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 channel 120, the contact area with the inner wall of the channel is small, and the volatile matter is not easy to adhere to the pipe wall. The hot air is sprayed vertically downward from the air inlet channel 120 to the gasification Inside the chamber 110, it flows along the tapered bottom surface of the gasification chamber 110. If the bottom surface is flat, the hot air blowing on the flat surface will have a greater reaction force. The hot air will spread to both sides, and the tapered bottom surface can guide The flow of hot air, the hot air enteri...

Example Embodiment

[0052] Embodiment three:

[0053] This embodiment proposes a method for controlling the concentration and temperature of volatiles 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 volatiles and a thermocouple 190 for detecting the temperature, and the amount of hot air inlet is adjusted by the detected temperature and concentration. The flow rate of hot air blowing 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 will automatically open the hot air regulating valve to increase the hot air intake air volume, thereby increasing the air The temperature in the chemical chamber 110 increases the vaporization rate of volatiles; similarly, when the VOC concentration detected by the VOC concentration monitor 180 is too high and exceeds the...

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 ...
