Abstract

The invention discloses a high-concentration saliferous organic waste liquid incinerator and an incineration technique, which belongs to the processing field of organic waste liquid. The high-concentration saliferous organic waste liquid incinerator comprises a horizontal furnace, a vertical furnace, an afterheat boiler, and a draught fan. The furnace end of the horizontal furnace is provided with a waste liquid burner, a coaxial burner, and a tangential burner. The furnace end of the horizontal furnace is also provided with a cyclone separator, an air preheater and the like. A retaining walland a cooling air system are arranged in the vertical furnace; the stability and pressure of each stage are controlled by the incineration technique; a low-heating value liquid carrier atomizing burning technology is used by the high-concentration saliferous organic waste liquid incinerator and incineration technique, and has excellent processing effects for high-concentration saliferous organic waste liquid, high-concentration saliferous organic waste water, waste oil and the like. The processing capacity is more than 2.0 tons per hour; the waste liquids can be completely burnt; the continuous running period is more than 30 days; the consumption of natural gas is less than 60 cubic meters for each ton of waste liquid; and the heat recycling volume of each ton of waste liquid is more than2.5 tons; therefore, the resources are effectively and circularly utilized.

Description

technical field [0001] The invention relates to a waste liquid treatment equipment and a process, in particular to a waste liquid incineration device and a process. Background technique [0002] High-concentration salt-containing organic waste liquids are widely found in new varieties of pesticides and pharmaceutical production devices. Because they contain some substances that pollute the environment, they need to be treated and then discharged instead of being discharged directly. [0003] The most commonly used treatment method is incineration. The characteristics of high-concentration salt-containing organic waste liquid are that the calorific value of the waste liquid is low, generally 10000kj / kg, and it is difficult to completely burn and decompose. At the same time, the inorganic salts in the waste liquid are not flammable, and may be deposited in the furnace and on the wall of the heat exchanger to block the flue gas flow passage and affect the continuous production...
