Description

System for reducing water consumption in titanium dioxide production

Technical Field

The utility model belongs to titanium white powder production field, concretely relates to reduce titanium white powder production water consumption system.

Background

In the production process of titanium dioxide by a sulfuric acid method, a plurality of pump equipment are provided, and especially under the condition that the capacity of a single set of production device is improved, the number of the pump equipment is multiplied. The single set of capacity of the existing sulfuric acid method titanium dioxide production reaches 10 ten thousand t/a, and the cooling water amount of pump equipment is about 1200m³And d, the pump shaft seal is easy to wear after running for a certain time, materials leak to flow into shaft seal cooling water, and engine oil and the like also enter the cooling water to cause the quality of the cooling water of pump equipment to be poor. At present, pump shaft seal cooling water of a titanium dioxide factory is basically long flowing water and is directly discharged to a trench, so that the water consumption of titanium dioxide production is high, and the sewage treatment capacity is increased, so that the power consumption of titanium dioxide production is high. The water consumption required by acidolysis leaching is large, the requirement on water quality is not high, and in order to reduce fresh water consumption and save water resources, pump cooling water is recycled as acidolysis leaching water, so that the water consumption in the production of titanium dioxide by a sulfuric acid method is effectively reduced. The present invention has been devised in view of such a situation.

Disclosure of Invention

The utility model aims at avoiding the not enough of prior art, providing a reduce titanium white powder production water consumption system.

In order to achieve the purpose, the utility model adopts the technical proposal that: a system for reducing water consumption in titanium dioxide production is characterized in that: sand filtration water house steward passes through each monomer floor, branch is a plurality of cooling water inlet branch pipes at each monomer floor respectively, the cooling water inlet branch pipe connects changes material pump bearing seal water inlet hose, change and set up the water collector on the material pump, change material pump bearing seal water outlet hose and insert the water collector, water collector exit linkage cooling water outlet pipe, cooling water goes out water piping connection cooling water recovery house steward and inserts underground collecting pit, set up the submerged pump in the collecting pit, leaching water pitcher and mountain flour beating bucket are connected respectively through the submerged pump to the cooling water retrieval and utilization pipe.

The cooling water inlet branch pipe is provided with a thermometer and an automatic regulating valve, the thermometer and the automatic regulating valve are controlled in an interlocking way, and the opening of a valve on the cooling water inlet pipe is automatically regulated according to the temperature to control the flow of cooling water.

The water pan is L-shaped, and a rubber bearing pad is arranged between the pump shaft of the material transferring pump and the water pan; the cooling water is prevented from flowing outwards, so that the shaft seal cooling water is completely recycled into the water receiving disc; and a screen is arranged on the water outlet of the water receiving tray to prevent impurities from entering the cooling water recovery header pipe.

The water receiving tray and the cooling water recovery header pipe are both provided with gradients of 2-5 per mill, so that smooth water flow is ensured; the cooling water recovery header pipe is arranged in the underground hidden groove, and the grid is arranged on the underground hidden groove.

The collecting pit in the middle of set up the overflow barricade, prevent that long-pending material impurity of aquatic from getting into leaching the water pitcher, guarantee that quality of water is up to standard.

The submerged pump is provided with two pumps, one pump is opened and the other pump is standby, and the control process is provided with high-low liquid level variable frequency control.

The cooling water backwater is preferentially used for acidolysis leaching water and then used for stone powder pulping.

The utility model has the advantages that: the system has simple and reasonable design and convenient operation. The cooling water can be recycled, the consumption of fresh water is reduced, and the water consumption in the production of titanium dioxide is reduced; the cooling water of pump equipment is systematically recycled, so that the environmental sanitation of the titanium dioxide production workshop is greatly improved. Meanwhile, the sewage treatment capacity is reduced, the power consumption is reduced, the energy conservation and consumption reduction are realized, the sewage discharge capacity is reduced, and the production cost of the titanium dioxide is effectively reduced.
