Description
Technical Field
The invention relates to the field of sodium silicate production, in particular to a kiln for producing sodium silicate.
Background
Sodium silicate commonly known as sodium silicate is a water-soluble silicate, and its aqueous solution commonly known as water glass is an ore binder. Industrially: the sodium silicate is usually prepared by calcining quartz powder and sodium carbonate at 1300-1400 ℃ to generate liquid sodium silicate, and then flowing out from a discharge hole of a furnace, blocking or water quenching to form particles, and then dissolving in high-temperature or high-temperature high-pressure water to prepare a solution-like sodium silicate product.
At present, a kiln for producing sodium silicate generally uses fuel gas, and the outer flame temperature of flame is highest in the combustion process of the fuel gas, but the kiln for producing sodium silicate generally only has one combustion tube, the height of flame cannot be adjusted, and the used fuel gas and combustion air are not preheated, so that the utilization rate of the fuel gas is not high.
Disclosure of Invention
The invention aims to provide a kiln for producing sodium silicate, which has the advantages of simple structure, high gas utilization rate and good combustion effect.
The technical scheme adopted by the invention is as follows: the utility model provides a kiln for producing sodium silicate, includes furnace body, material conveyer belt, be equipped with feed inlet, exhaust port, discharge gate and combustion port on the furnace body, the exhaust port is located the furnace body top, the discharge gate is located the furnace body bottom, be equipped with first gas pipe, second gas pipe and combustion air pipe in the combustion port, all be equipped with the nozzle on first gas pipe and the second gas pipe, the nozzle is vertical upwards on the first gas pipe, the nozzle slope sets up on the second gas pipe, combustion air pipe is arranged in first gas pipe and second gas pipe below, be equipped with the air nozzle on the combustion air pipe, first gas pipe, second gas pipe and combustion air pipe all stretch into the furnace body, first gas pipe and second gas pipe all connect the gas preheating chamber, and all are equipped with gas switch on first gas pipe and the second gas pipe, the combustion air pipe connects the air preheating chamber.
Preferably, the feed inlet is connected with a material conveyor belt.
Preferably, the air nozzle is located at a gap between the first gas pipe and the second gas pipe.
Preferably, the inclination angle of the burner on the second gas pipe is 15-30 degrees.
The invention has the advantages that: the first gas pipe nozzle is vertical upwards, the nozzle slope sets up on the second gas pipe, and all be equipped with gas switch on first gas pipe and the second gas pipe, can be according to the how many of material in the furnace body, confirm which gas pipe is used, perhaps use two gas pipes simultaneously, make the nozzle spun flame high temperature area of gas pipe be located the material in the furnace body, help practicing thrift the gas, combustion air pipe is located two gas pipes below simultaneously, and the air nozzle on the combustion air pipe is located first gas pipe and second gas pipe gap department, help the abundant burning of gas more, first gas pipe and second gas pipe are all connected the gas preheating chamber, combustion air pipe connects the air preheating chamber, after preheating reburning, the combustion effect is good, fuel utilization ratio has been improved.
