Abstract

The invention provides a low-flash-point liquid nitrogen protection system. A low-temperature liquid storage tank, a low-temperature liquid vaporizer, a tube pass type water bath heater, a nitrogen storage tank and a hazardous waste storage tank of the protection system are sequentially connected, wherein the hazardous waste storage tank and an auxiliary fuel storage tank are connected with a brick return kiln; an auxiliary fuel and volatile flash liquid waste switching gate is arranged at the pipeline intersection position of the hazardous waste storage tank and the auxiliary fuel storage tank; the brick return kiln is connected with a waste heat boiler; and the waste heat boiler is connected with an interlayer inner pipeline of the hazardous waste storage tank. The technical problems that the requirement for the storage process of low-flash-point volatile liquid waste is very high, and volatilization is very likely to happen are solved. Liquid nitrogen utilized in the low-flash-pointliquid nitrogen protection system can effectively maintain that the liquid is stored at the temperature lower than the flash point temperature, nitrogen formed after temperature rise can conduct gaseous protection on the interior of the liquid storage tank and the incineration auxiliary fuel, the isolation function can be achieved, nitrogen is inert gas, and harm is not likely to happen.

Description

technical field [0001] The invention relates to a low-flash point liquid nitrogen protection system, which belongs to the technical field of environmental protection equipment and relates to hazardous waste incineration storage technology. Background technique [0002] The incineration process is one of the effective means for the harmless treatment of hazardous waste. Usually, different types of hazardous waste solids are mixed and stirred, and the solid waste is sent to the incineration rotary kiln for incineration through a grab bucket. However, some liquid hazardous waste cannot be grabbed by the grab bucket and sent to the rotary kiln for incineration. At this time, it needs to be sprayed into the rotary kiln by pipeline pump for incineration. However, the storage process of this low-flash point, volatile liquid waste is very demanding, and this unstable liquid hazardous waste is easy to volatilize. Contents of the invention [0003] In order to solve the technical p...
