High-concentration salt bearing liquid waste incinerator and high-concentration salt bearing liquid waste treatment method

Abstract

The invention discloses a high-concentration salt bearing liquid waste incinerator and a high-concentration salt bearing liquid waste treatment method, relates to the technical field of liquid waste treatment equipment and techniques, and aims to solve problems that purging devices in the conventional liquid waste treatment equipment cannot thoroughly remove inorganic salt powder attached to the inner wall of equipment, the safe operation of the equipment is affected, and the conventional treatment method is low in work efficiency and safety factor. The incinerator comprises an incinerating furnace, an afterheat recycling device, a tail gas purifying device and an induced draft fan which are sequentially connected with one another; a feeding opening of the incinerating furnace is connected with a main separating chamber for separating inorganic salt; and the main separating chamber is communicated with a high-temperature smoke feeding tube and a liquid waste feeding tube. The high-concentration salt bearing liquid waste treatment method comprises the following steps of: (a) separating the inorganic salt; (b) incinerating at high temperature; (c) recycling afterheat; and (d) purifying tail gas. The high-concentration salt bearing liquid waste incinerator and the high-concentration salt bearing liquid waste treatment method are particularly applicable to purifying high-concentration salt bearing liquid wastes.

Description

technical field [0001] The invention relates to the technical field of waste liquid treatment equipment and process methods, in particular to a high-concentration salt-containing waste liquid incineration device and a treatment method thereof. Background technique [0002] With the development of industry, the high-concentration refractory organic waste liquid discharged from pharmaceutical, chemical and other industries is increasing day by day. If it is discharged without treatment, it will cause serious pollution to the environment. The components of the waste liquid are usually: salt in a saturated state, some organic matter, and the rest is water. Although the traditional treatment technology can effectively remove COD, N, P and other pollutants in the waste liquid, it consumes more energy and resources during the treatment process, which is actually "dissipating energy with energy". In addition, A large amount of residual sludge is also produced. It can be seen that ...
