Problems solved by technology

[0003] At present, in the flotation process, collectors for improving the hydrophobicity of the coal particle surface and foaming agents for reducing the gas-liquid interfacial tension are mostly used for reagent addition; Chinese patent document CN 103736599A discloses an emulsification device, which includes a mixing pump, A water source, a water inlet regulator, an air inlet regulator and an emulsifier. The emulsifier consists of a shell whose internal space is divided into a front chamber and a rear chamber by a partition with a narrow hole. Air and water are mixed. When the body passes through the narrow hole, it forms an emulsified state due to cavitation. Due to the emulsification, the agent is highly dispersed to form a misty aerosol, which increases the stability of the flotation agent emulsion and prevents it from forming large oil droplets, thereby improving the chemical and pulp. The contact area increases the flotationability of minerals and improves the flotation yield. The application of this device in flotation will greatly improve the effect of pulp pretreatment, but the device is easy to block the slit and affect the emulsification effect, and the device needs Adjust and control the air and water to form high-pressure saturated gas-liquid, which cannot achieve stable operation effect

Abstract

The invention discloses a coal slime water flotation reagent vaporizing device and a vaporizing method thereof. The coal slime water flotation reagent vaporizing device comprises a reagent barrel, wherein the reagent barrel communicates with a vaporizing container through an electric control valve I, a high pressure pump, an electric control valve II and a spray nozzle; the part, at the upper end of the container, of the vaporizing container is connected to an electric heating tube; an electric control valve III used for collecting the vaporizing reagent is arranged on the electric heating tube; a temperature monitoring device and a pressure monitoring device for monitoring the temperature and the pressure of the inner part of the container are arranged on the vaporizing container; and the vaporizing container is further connected with a vacuum-pumping pipeline which communicates with the reagent barrel. The vaporizing container comprises a plurality of electric heating plates which are arranged on the inner part of the container, wherein the heating temperature of the electric heating plates is gradually increased from top to bottom; and the part, at the outlet of the electric control valve III, of the electric heating tube is further provided with a flow monitoring device. The device is further provided with a control system which is electrically connected to the monitoring devices, the electric control valve, the electric heating tube, the high pressure pump, the vacuum pump and the electric heating plate. The device is simple in structure, and is stable to operate, and the contact area of the reagent and coal slime water is sufficiently increased.

Description

technical field [0001] The invention belongs to the technical field of coal slime water flotation, and in particular relates to a coal slime water flotation agent vaporization device and a vaporization method thereof. Background technique [0002] Coal slime water is the medium water produced in the process of coal separation and processing. Coal slime water is one of the main sources of pollution in the coal industry. The main task and purpose of the coal slime water treatment system is to recover fine particles of different qualities from a large amount of coal slime water The product and the recycling water suitable for the coal preparation plant can realize the closed loop washing water, and whether the discharge can meet the requirements of environmental protection will seriously affect the economic and social benefits of the coal preparation plant. Therefore, slime water treatment is a very important link in the production process of coal preparation plant. [0003] A...
