Problems solved by technology

At present, the general way to deal with laboratory solid waste and waste liquid is to collect them in a centralized manner and then transport them to treatment institutions for treatment. This method does not deal with waste in time, and there are safety hazards such as leakage, and the treatment cost of professional companies is high.
The treatment process of professional treatment companies for different solid wastes and waste liquids with different components is cumbersome and costly

Embodiment 1

[0066] The invention provides a centralized and real-time processing system for laboratory waste, the structure of which is as follows: figure 1 As shown, it includes: waste liquid storage tank 1, waste liquid neutralization device 2, waste liquid buffer device 10, premixing device 3, primary reaction device 4, particle collection device 5, particle storage tank 6, secondary reaction device 7 , Secondary air supply device 8, purification device 9.

[0067] The function and structure of each device are as follows:

[0068] Waste liquid storage tank 1, used for storing the collected waste liquid;

[0069] The waste liquid neutralization device 2 is used to neutralize the waste liquid to form waste liquid to be treated. It is provided with a pH meter 21, an acid adding unit 22 and an alkali adding unit 23. Wherein the pH meter 21 is used to measure the pH value of the waste liquid; the acid adding unit 22 is used to provide the acid solution and joins the acid solution in the ...

Embodiment 2

[0100] Embodiment 2 is the same as Embodiment 1, and also includes a waste liquid storage tank 1, a waste liquid neutralization device 2, a pH meter 21, an alkali addition unit 22, an alkali addition unit 23 waste liquid buffer device 10, a premixing device 3, and a mist Catifier 31, primary tuyere 32, injector 33, primary reaction device 4, particle collection device 5, particle storage tank 6, secondary reaction device 7, secondary air supply device 8, purification device 9, spray tower 91, Activated carbon adsorption device 92, dust removal equipment 93, chimney 94 and liquid collection device 95. The difference is the structure of the primary mixing plate 41 and the secondary mixing plate 42 in the primary reaction device 4 in the second embodiment.

[0101] The structure of the primary mixing plate 41 in the second embodiment is as follows Figure 4-4 , the structure of the secondary mixing plate 42 is as follows Figure 4-5 . combine Pic 4-1 and Figure 4-4 , there...

Embodiment 3

[0108] The difference between Embodiment 3 and the above-mentioned Embodiment 1 and Embodiment 2 is that the primary reaction device 4 has an inverted pyramid structure as a whole, such as Figure 6 shown. In the third embodiment, the primary mixing plate 41 and the secondary mixing plate 42 are also provided, and the structure of the two-stage mixing plate may be the same as that of the primary mixing plate 41 and the secondary mixing plate 42 in the first and second embodiments. The rest of the components in the third embodiment are the same as those in the first and second embodiments, and will not be described in detail here.

Abstract

The invention relates to a centralized and real-time processing system for laboratory waste. A waste liquid neutralizing device is used for neutralizing waste liquid according to the monitored pH value of the waste liquid; a waste liquid caching device is connected with the waste liquid neutralizing device; a premixing device is connected with the waste liquid caching device, an atomizer is arranged on the premixing device, and a primary wind hole for introducing air is formed in the premixing device; a first-stage reaction device is used for carrying out evaporation and cleavage reaction on awaste gas-liquid-solid mixture conveyed from the premixing device; a micro-particle collection device is used for collecting solid micro-particles separated from the first-stage reaction device; other waste gas-liquid mixtures are collected into a second-stage reaction device from an outlet of the micro-particle collection device; a temperature monitoring point and a secondary wind pipe for introducing hot air are distributed on the second-stage reaction device; a signal end of the temperature monitoring point is connected with a control end of an adjusting valve of a secondary wind supply device; and a purifying device is used for purifying secondary-stage products separated from the second-stage reaction device. The centralized and real-time processing system is high in integration level, compact in structure, low in single amount processing cost of waste and high in processing efficiency.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to a centralized real-time treatment system for laboratory waste. Background technique [0002] With the rapid development of science and technology in our country, the laboratories of universities, scientific research institutions and enterprises have been continuously expanded, and the types, quantity and scale of laboratories have also continued to grow, followed by pollution problems caused by laboratories. Laboratory pollutants mainly include: solid waste, waste liquid, exhaust gas, noise and vibration, electromagnetic radiation, and biological pollutants of viruses and pathogenic bacteria. University laboratory waste is highly toxic and harmful, but the environmental protection department has not included it in the environmental protection testing items. Even if it is included, it is difficult to detect because of its small amount and easy dilution by domestic sewage. However, ...
