Problems solved by technology

[0016] To sum up, almost all the mixed liquid mass transfer and chemical reaction and product separation and recovery processes have to varying degrees the existence of many process units, bulky units and large footprints, or discontinuous treatment, or long duration, open-air Or dewy smell, wear and fouling of connecting pipes and pumps, heavy work of removing sediment in sedimentation tanks, and high cost in separation technology
High operating failure rate, high energy consumption, and large investment are common problems in these processes and systems, and some processes are too inefficient and need to be reused
There are some chemical processes and systems for wastewater treatment. Although the wastewater treated by the system is expensive, it still cannot meet the discharge standards required by environmental protection.

Embodiment 1

[0140] see figure 1 , which is an integral aeration gas flotation gas-liquid mass transfer chemical reaction tank designed according to the technical scheme of the present invention, used for mass transfer and product separation of aeration, air flotation, stripping, stripping, and for Chemical reactions such as neutralization, oxidation, reduction, acid-base salt precipitation and product separation, used for crystallization and crystal separation.

[0141] The reaction tank includes an upright swirl chamber 7, a transmission device 3, a pin wheel 8, a slurry mixer 10, an aeration device 9, and a flotation material skimming device.

[0142] Transmission device 3 is made up of motor, bearing box, power transmission shaft, belt pulley 2 etc. The stirrer rotor is coaxial with the swirl chamber 7. The transmission device 3 is located at the top of the swirl chamber 7, the transmission shaft extends below the middle position in the chamber, and the agitator is fixed on the trans...

Embodiment 2

[0150] see figure 2 , which is a multi-head aeration air flotation gas-liquid mass transfer chemical reaction tank designed according to the technical scheme of the present invention, used for aeration, air flotation, stripping, stripping and product separation for mass transfer and product separation. Chemical reactions such as neutralization, oxidation, reduction, acid-base salt precipitation and product separation, used for crystallization and crystal separation.

[0151] The reaction tank includes an upright swirl chamber 7, a transmission device 3, a pin wheel 8, a slurry mixer 10, an aeration device 9, and a flotation material skimming device. The difference from Example 1 is:

[0152] The aeration device 9 adopts the form of multiple aeration scattered arrangements, and the air inlet 13 is on the side wall of the housing;

[0153] A number of overflow ports 19 are left on the shell, and the upper opening of the swirl chamber is covered and connected by flanges;

Embodiment 3

[0157] see image 3 , which is a swirling liquid-liquid mass transfer chemical reaction tank designed according to the technical scheme of the present invention, used for coagulation, extraction, mass transfer and product separation, used for neutralization, oxidation, reduction, acid-base Salt precipitation is a kind of chemical reaction and product separation, which is used for crystallization and crystal separation.

[0158] The reaction tank includes an upright swirl chamber 7, a transmission device 3, a pin wheel 8, a slurry dispenser 10, and a liquid spraying device. The difference with embodiment two is:

[0159] There is no aeration device 9, no flotation material skimming device, and no pedestal 5;

[0160] The liquid spraying device is composed of a plurality of atomizing nozzles 20, radially distributed liquid spraying pipes, and joints. The dosing port 21 is fixed on the cover plate;

[0161] The sizing port 17 of the swirl bin is a sizing port.

Abstract

The present invention relates to the technology of chemical reactor. The equipment includes transmission mechanism, pin wheel, aerator, liquid sprayer, slurry compounding device, light phase skimmingdish and decanter. The present invention has composite pin wheel stirrer and thus the small start power consumption, efficient shearing aeration and chemical dispersion and high mass-transferring andreaction efficiency. In the present invention, vortex centrifugation is applied to complete simultaneous clarification, floatation and separation. The present invention may be used in neutralization,oxidation, reduction, chemical reaction, stripping, etc.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical mass transfer and chemical reactor and product separation thereof, and relates to tank reactor and equalization tank technology, and relates to flotation, aeration, coagulation, neutralization, oxidation, reduction, acid-base salt precipitation, extraction , stripping, stripping, crystallization technology, also involves centrifugal sedimentation technology. 2. Background technology [0002] Reaction tanks and reactors are commonly used equipment in the fields of chemical industry and environmental protection. The open-air one is a pool, and the closed one is a vessel. [0003] The main purpose of a class of reactors (pools) is to produce new substances from one or several simple substances at a certain pressure or temperature. In this type of reactor, the tank reactor is the most common. As a commonly used equipment in chemical production, it is used to complete the sulfonation, nitration, ...
