Description

Sulfur burning furnace

Technical Field

The utility model relates to a sulfur combustion furnace, and belongs to the technical field of combustion furnaces.

Background

The corn starch industry is provided with an acid making working section, the prepared sulfurous acid is used for soaking corn, the protein net at the periphery of the corn grains is destroyed after soaking, and the starch grains wrapped by the protein net are released, so that the separation of fibers and proteins is facilitated. The sulfur combustion furnace is an important device of the acid making working section, sulfur is fully combusted in the sulfur combustion furnace to form sulfur dioxide gas, and sulfur dioxide is absorbed by the absorption tower to generate sulfurous acid.

Sulfur burners are generally classified into two types, one type of sulfur burner using liquid sulfur as a combustion form; a combustion form is formed by gaseous sulfur. The two forms of sulfur burning furnaces have very different structures, wherein the liquid sulfur burning furnace mainly comprises a sulfur melting chamber, a burning disc, a furnace body, an air inlet cover plate and the like. The combustion disc is arranged in the furnace body, and in order to increase the combustion quantity, the combustion area needs to be increased, so that an upper layer of combustion disc and a lower layer of combustion disc are generally arranged in the furnace; the sulfur melting chamber is generally arranged above the upper layer combustion disk and is used for storing liquid sulfur. The liquid sulfur flows out from a discharging opening arranged at the lower part of the liquid sulfur and flows onto an upper layer combustion disk to be continuously combusted, sulfur dioxide gas formed by combustion is discharged from an upper exhaust port and enters a sulfur dioxide absorption tower to form sulfurous acid.

When the sulfur burning furnace works, firstly solid sulfur is filled and put on the upper burning disc manually, the solid sulfur is ignited, after a period of burning, the temperature in the hearth begins to rise, and after reaching a certain temperature, the solid sulfur is sent into the sulfur melting chamber. A plug or valve core is generally arranged at the blanking port of the sulfur melting chamber, and the plug needs to be plugged when the sulfur melting chamber begins. After the sulfur in the sulfur melting chamber is melted, the upper hand wheel is rotated to drive the plugging head to rise, the blanking opening opens a certain gap, and the liquid sulfur flows down on the first layer of combustion disc to be combusted, so that the required sulfur dioxide gas is generated. When more and more liquid sulfur in the first layer of burning disc can not be timely burnt, the depth of the liquid sulfur is deeper and deeper, and the liquid sulfur flows down from the middle overflow port of the upper layer of burning disc after reaching a certain height and falls into the second layer of burning disc to continue burning.

The existing sulfur combustion furnace has the following defects in the production process: 1. the continuous combustion of sulfur ensures that the temperature inside the furnace body is higher and higher, hot sulfur dioxide gas is pumped away and naturally cooled only by the exhaust port, the temperature inside the furnace is difficult to be reduced, the temperature inside the furnace can reach 600-700 ℃ generally, the influence on steel parts of the furnace body is relatively large, the steel parts are easy to ablate, deform and damage, and frequent maintenance and replacement are required;

2. the sulfur melting chamber is located at the upper part of the furnace body, and when the temperature in the furnace body is increased, the temperature of the sulfur melting chamber is also increased. The sulfur generally begins to melt at about 115 ℃, the fluidity of the liquid sulfur is best at 130-150 ℃, and the sulfur becomes viscous when the temperature exceeds 170 ℃, so that the melted sulfur cannot smoothly flow onto the upper-layer combustion plate. Furthermore, when the temperature is too high, sulfur is sublimated directly, so that the sulfur cannot smoothly enter a combustion disc to be combusted;

3. the traditional combustion disk is made of stainless steel thin plates, deformation is large at high temperature, the supporting guide rail is also made of bending pieces, the deformation is obvious, the combustion disk is not smooth enough, liquid sulfur cannot be uniformly spread on the whole area of the combustion disk, the combustion area is small, and the combustion yield is insufficient;

4. when the temperature is too high, sulfur is easily sublimated into sulfur particles, and the sulfur dioxide gas is pumped away by negative pressure and is settled on a process pipeline, so that the pipeline is blocked, and the system cannot work normally;

5. the sulfur melting chamber is fixed and has no heat insulation cooling structure, so the temperature cannot be controlled by adjusting the sulfur melting chamber, and the combustion flame can be adjusted only by manually and frequently adjusting the feeding amount, so that the sulfur melting chamber has hysteresis, is time-consuming and labor-consuming and has poor effect; in addition, the field environment is bad, and the physical and psychological health of operators is affected;

6. the plug at the bottom of the sulfur melting chamber is opened to enable liquid sulfur to flow down, but a gap is inevitably formed after the plug is opened, when the flame of the upper combustion disc is higher, the flame is easily strung into the sulfur melting chamber from the gap, so that the sulfur melting chamber catches fire, the sulfur melting chamber is communicated with a feeding pipe, once the inside of the sulfur melting chamber catches fire, the fire easily reaches the upper feeding dragon and the storage bin along the feeding pipeline, and huge potential safety hazards are caused.

The liquid sulfur outflow port is provided with a liquid seal pipe 4c extending upwards, the upper end of the liquid seal pipe 4c is provided with a plurality of notches, the upper port of the liquid seal pipe 4c is covered with a liquid seal cover 4d, and the peripheral edge of the liquid seal cover 4d extends downwards and is lower than the notches at the upper end of the liquid seal pipe 4c. The liquid sulfur bypasses the lower edge of the liquid sealing cover 4d and flows down from the notch at the upper end of the liquid sealing pipe 4c, so that the smoothness of flow is ensured, a good liquid sealing effect is formed, and the flame of the combustion chamber is prevented from being strung into the sulfur melting chamber 4.

The bottom wall of the sulfur melting chamber 4 is provided with a cooling coil 7, the cooling coil 7 extends outwards from the middle area of the bottom wall of the sulfur melting chamber along the vortex line, a distance is kept between the cooling coil 7 of the inner ring and the liquid seal pipe 4c, so that the temperature of the most central area is the highest, and sulfur at the cooling coil 7 is melted first and flows downwards. The cooling coil water inlet 7a is connected with the cooling coil of the inner ring, and the cooling coil water outlet 7b is connected with the cooling coil of the outer ring. When the temperature of the sulfur-melting chamber 4 exceeds a set temperature value, the cooling water flows through the cooling coil 7 to take away part of heat, so that the temperature of the sulfur-melting chamber 4 is reduced to be within a reasonable range.

On one hand, the sulfur burning furnace is expected to improve the yield, namely the burning amount of sulfur is large, on the other hand, the temperature in the furnace is too high, so that steel structural members are damaged, the sulfur is easily sublimated into sulfur particles, a pipeline is blocked, and the normal operation of a system is influenced. In order to control the temperature in the furnace, the outer wall of the furnace body is provided with a cooling jacket 8, so that the temperature of the inner wall of the furnace body is reduced, the excessive temperature of a combustion chamber is avoided, sublimed sulfur is generated, the protection of steel parts in the furnace is facilitated, and the service life of the steel parts in the furnace is prolonged.

In order to facilitate water flow organization and avoid short flow of cooling water, the cooling jacket 8 is divided into two halves from the top of the furnace body, jacket cooling water ports are respectively arranged at the top and the bottom of the two cooling jackets 8, and a plurality of jacket baffle plates 8c are respectively arranged in the inner cavity of the cooling jacket 8 along the horizontal direction. Cooling water can enter the cooling jacket 8 from jacket cooling water inlets 8a at the upper parts of two sides, flow downwards in an S shape under the baffling guide of a plurality of jacket baffle plates 8c, and finally flow out from jacket cooling water outlets 8b at the bottom, so that the flow path of the cooling water is prolonged, the heat exchange efficiency is improved, no cooling blind area is generated, and the maximum heat exchange area is fully utilized; the cooling water flow direction may also be reversed.

The defects such as weld cracking and the like are easily caused by cold and hot alternation in the furnace body, sulfur dioxide gas is generated by combustion in the equipment, and once the cooling jacket 8 leaks water in the equipment, sulfurous acid is formed, so that serious corrosion phenomenon is generated on equipment components; therefore, all welding seams of the cooling jacket 8 are designed on the outer side, and can be found timely and convenient to maintain.

The outlet end of the combustion chamber is provided with a plurality of smoke baffle plates 9, and the adjacent smoke baffle plates 9 are arranged in a staggered way to form a labyrinth structure, so that sublimed sulfur particles formed by insufficient combustion can be deposited and prevented from entering a subsequent process pipeline. Because the smoke baffle plate 9 is a vulnerable part, the smoke baffle plate is made of high-temperature resistant ceramic materials; the two sides of each smoke baffle plate 9 are respectively inserted into slots on the inner wall of the furnace body, and are not fixed with the furnace body, so that the smoke baffle plates are convenient to replace after being damaged.

The exhaust port 1c is arranged at the top of the rear end of the furnace body, namely above the tail end flue, the exhaust port 1c is of a dome structure, and the purpose is to settle sublimated sulfur particles, namely, in case the particles pass through the smoke baffle plate 9 of the final stage, the particles can also settle at the square joint circle, so that the particles do not enter the following pipelines and equipment to the greatest extent. The sulfur dioxide gas generated by combustion is discharged from the exhaust port 1c and enters a subsequent sulfur dioxide absorption tower to form sulfurous acid required by soaking the corn.

The cleaning opening 1h which can be opened and closed is arranged at the lower end of the rear side of the furnace body, and the furnace body is opened regularly to clean the settled sublimated sulfur particles.

The sulfur combustion furnace is just ready to work, and the sulfur melting chamber 4 is positioned at a low position and is relatively close to the upper layer combustion disk 2. Firstly, solid sulfur needs to be manually added from an access hole 1g1 on an access door cover 1g, and is ignited, the solid sulfur burns to generate heat, and the temperature in a furnace body and the sulfur melting chamber 4 gradually rises.

After the combustion chamber reaches a certain temperature, automatic feeding is started, sulfur is put into the sulfur melting chamber 4 from the feed pipe 5, solid sulfur begins to melt after entering due to the certain temperature of the sulfur melting chamber 4, a liquid sulfur layer is formed at the bottom of the sulfur melting chamber, and after reaching a certain height, the sulfur flows down from the middle liquid seal pipe 4 c; since the liquid seal cover 4d covers the upper part and the outer periphery of the liquid seal pipe 4c, a liquid seal is formed therein, and the flame in the lower part cannot enter the sulfur melting chamber 4 therethrough.

When the liquid sulfur is fully paved on the whole upper layer combustion disk 2, if the combustion amount is less than the blanking amount, the liquid sulfur can be higher and higher on the upper layer combustion disk 2, finally flows down from overflow ports on the upper layer combustion disk 2, flows to the lower layer combustion disk 3 and continues to burn, and finally, the state that two layers of combustion disks burn simultaneously is achieved.

Along with the combustion, the temperature of the combustion chamber and the sulfur melting chamber 4 is higher, but the fluidity of the liquid sulfur is better only when the liquid sulfur is controlled at a certain temperature, so that the liquid sulfur can smoothly flow down from the sulfur melting chamber 4; at the same time, too high a temperature will also lead to the production of sublimed sulfur particles, which will also adversely affect the mechanical structure of the apparatus itself, so that the furnace body and the sulfur melting chamber 4 will be temperature-controlled.

Cooling water is introduced into a cooling jacket 8 outside the furnace body to cool, and cooling water is introduced into a cooling coil 7 of the sulfur melting chamber 4 to cool, so that the temperatures of the combustion chamber and the sulfur melting chamber 4 are controlled within a required range. Meanwhile, part of heat is recovered by the cooling water, so that the cooling water can be used for workshop production, the energy utilization rate is improved, and the economic benefit is improved.

Because the flame of the upper layer combustion disk 2 directly heats the sulfur melting chamber 4, when the combustion amount is relatively large, the flame is relatively vigorous and high, the temperature of the sulfur melting chamber is quickly increased, and the cooling water alone may not be enough to effectively cool the sulfur melting chamber. When the temperature of the sulfur melting chamber 4 is still overhigh, the lifting motor 10 is started, the lifting shaft 6 is driven to move upwards through the lifting speed reducer 11, the lifting shaft 6 suspends the sulfur melting chamber 4 to move upwards for a distance, the rapid cooling is facilitated, when the temperature is lower than a certain value, the lifting motor 10 is started again, the sulfur melting chamber 4 is lowered by a certain height, and therefore the temperature of the sulfur melting chamber 4 can be automatically regulated by the height, and the fluidity of liquid sulfur is ensured.

The PLC is connected with components such as a temperature sensor, a travel switch and a flowmeter, so that the automation of whole temperature adjustment can be realized, the labor intensity of workers is greatly reduced, and bad states such as hysteresis quality, wrong operation and the like of manual adjustment are avoided; meanwhile, due to the severe field environment, workers are liberated from the first line of the combustion furnace, and the combustion furnace is beneficial to the physical and mental health of staff.
