(4), laboratory waste liquid incineration device:
1, incinerator comprises the following equipment:
Liquid atomization system (waste liquid storage tank, liquid pressure pump, liquid conveying pipeline and control device, air compressor, air pressure pipe and control device), supplemental oxygen blower and air supply system, furnace body, gas burner, G-L heat exchanger, packed tower, demister, induced draft fan, chimney, the combustion chamber temperature automatic control system, electric control system, spray washing system (spray pump, spray pipe and control device), other connection pipeline, operating platform
2, the process description:
First, the normal operation of the equipment operation, ensure that the change has the right amount of tap water heater, open the fan, spray system for furnace purging oxygen supply fan, then open the gas burner. When the furnace temperature display instrument display to the set, open water spray system and compressed air system, water is sprayed into the furnace body of the high-temperature incineration mist, the flame through a along the high temperature flue gas pipeline in a direction tangential furnace charge into a flame column body and into the air, circling discharged from the furnace body. Waste and wastewater by high temperature pyrolysis and incineration to no smell, no odor, smokeless combustion effect, so that the burning and destruction and removal rate of more than 99.99%. High temperature flue gas generated in G-L heat exchanger recycling hot water heating, to achieve comprehensive utilization of heat energy; flue gas cooled into the packed tower, the spray washing to remove harmful components in flue gas, removing vapor in flue gas by water mist separator, protection of the subsequent equipment; the exhaust fan will be treated gas into the chimney into the atmosphere.

Note: the incinerator is not suitable for dealing with the flame retardant material and high halide waste.

3, equipment description:

1) incineration furnace
(1) the device to the atomization, internal mixing type two fluid atomizer. The degree of mixing, atomization, combustion speed and efficiency is excellent, the excess air coefficient is low, only 1.1 times so as to reduce consumption for heating air fuel. Atomizer nozzle diameter, the fluid viscosity, impurities content requirements is not high, not easy to be blocked by low pressure spray: high-pressure spray gun, more safety, not easy to wear, not easy to fault, good burning effect.

(2) high safety, before the start of a not off explosive gas ignition function cannot, in order to prevent gas explosion: design a residual burn timing device, to ensure that the furnace without residual explosible gas, burner with a photosensitive tube detection, once the flameout or ignition failure, immediately quick automatic cut off the gas path, safe and reliable. The other atomization pressure and temperature chain, once the occurrence of high temperature or abnormal, immediately stop waste water supply, alarm system, the entire operation system operation in instrument control.
 
(3) due to the adoption of this technology, the equipment is simplified, lower cost, easy maintenance.

(4) the waste furnace front and cone combustion head high alumina refractory alumina containing 75%, resistance to high temperature corrosion.

(5) no two pollution - multi section air feeding system, can reduce emissions in combustion process NOX, as the best technology at present waste combustion technology to reduce NOX pollution.

2) pipeline district assembly are filters, pumps, valves and pressure detection instrument, conveying circuit etc..

3) the atomization system for incineration technology Guan Jian, this system uses all foreign atomization technology design, compressed air is adjusted to a constant pressure into the nebulizer and liquid mixing atomizer, from out due to the pressure release is dispersed into small droplet, which greatly increase the burning of total surface area, reduce the waste organic fully burning effective retention time required, reducing fuel consumption; and the design of circuit system, can ensure the fog particle in a constant state of gasification, the fast and good burning effect.

4) air supply system consists of low noise, high pressure blower transported into the bellows, air through a special nozzle for multi segment into the furnace body combustion chamber, increasing the combustion air volume, the destruction of organic matter by up to 99.99%.

5) heat exchanger
Make full use of high temperature flue gas after combustion, into heat energy recovery and utilization, and the flue gas temperature, reduce the operating cost to produce the best benefit.
