Description
Technical Field
The invention relates to a gasifier, in particular to a fixed bed slag gasifier distributing temperature control device.
Background
In the existing fixed bed slag gasification technology, raw material coal and other solid carbonaceous materials are fed into a gasifier from the top of the gasifier, and gasification raw materials with fluidity such as heavy oil and the like are fed into the gasifier from the gasifier body, and oxygen and water vapor are introduced into a fuel bed by using a nozzle to gasify at high pressure and high temperature. The product gas generated by gasification is collected by the upper space of the gasification furnace and then sent to the subsequent treatment process from the product gas outlet.
The applicant researches find that when the bed layer fluctuates or the feeding uniformity and the proportion of raw coal and other carbon-containing substances fluctuate, the temperature of the product gas in the upper space of the gasification furnace and the outlet of the product gas fluctuates, and the temperature of the product gas is regulated by adding heat exchange equipment outside the gasification furnace, so that the upper part of the gasification furnace cannot be protected, and a pipeline between the product gas and subsequent treatment equipment can be damaged due to the influence of the high temperature or the temperature, and the problem of fluctuation of the product gas temperature of the gasification furnace is not solved from the source.
Disclosure of Invention
The invention aims to provide a fixed bed slag gasifier material distribution temperature control device, which solves the problem that the feeding fluctuation of the existing gasifier and the product gas temperature fluctuation of the gasifier cause damage to the upper part of the gasifier and the pipeline between the product gas and subsequent treatment equipment.
In order to solve the technical problems, the invention adopts the following technical scheme:
the fixed bed slag gasifier material distribution temperature control device is arranged on the gasifier and comprises a buffer bin, wherein the buffer bin is arranged above a gasifier feed inlet, an opening is formed in the upper part of the buffer bin, and the lower part of the buffer bin is communicated with the gasifier feed inlet; the upper part of the buffering bin is provided with a feeding nozzle which is communicated with a flowable raw material feeding pipe, and the flowable raw material feeding pipe is provided with a feeding regulating valve.
Heavy oil and other gasifying material with flowability enter the upper part of buffering bin via the feeding pipe, and are sprayed via the feeding nozzle to feed coal and other carbon containing matter via the upper opening of buffering bin. Heavy oil and the like are mixed with raw material coal and other carbon-containing substances, then enter the gasification furnace through a gasification furnace feed inlet under the action of self gravity and enter various beds of the gasification furnace under the action of self gravity. In the mixing process in the buffer bin, the gasified raw materials with fluidity such as heavy oil and the like are adsorbed and bonded by raw material coal and other carbon-containing substances, so that the raw materials can be uniformly mixed and adsorbed and bonded without any stirring device, more solid powdery raw materials, heavy oil and the like enter a gasification reaction bed layer to participate in gasification reaction, and the quantity of the solid powdery raw materials carried by product gas out of a gasification furnace is reduced; meanwhile, the heavy oil and the like have fluidity, so that the process of enabling the gasified raw materials to enter the reaction zone absorbs heat carried in the product gas, adjusts the temperature of the upper part of the gasifier and the product gas, improves the comprehensive heat efficiency of the gasifier, and plays a role in temperature regulation and protection on the upper part of the gasifier and pipelines between the product gas and subsequent treatment equipment. In addition, the feeding amount of the raw materials with fluidity such as heavy oil is regulated by regulating the feeding regulating valve arranged on the feeding pipe of the raw materials with fluidity, namely, the proportion of the raw materials with fluidity such as heavy oil, raw coal and other carbon-containing substances is regulated, so that the temperatures of the upper part of the gasifier and the product gas are stably controlled.
Preferably, the product gas outlet of the gasification furnace is higher than the bottom end of the feed inlet of the gasification furnace. The product gas gives an upward force to each raw material, so that the dead time of each raw material is improved, the raw materials are fully reacted, and meanwhile, the product gas is reduced to bring out powdery substances.
Preferably, a temperature measuring device is arranged at the upper part in the gasification furnace, a cooling water spray head is arranged below a product gas outlet in the gasification furnace, the cooling water spray head is communicated with a cooling water pipe, and a cooling water regulating valve is arranged on the cooling water pipe. The cooling water is sprayed and atomized through a cooling water regulating valve and a cooling water pipe and is contacted and mixed with the product gas from each bed layer of the gasification furnace, so that the temperature of the upper part of the gasification furnace and the product gas is quickly regulated and stabilized, and the overtemperature of the upper part of the gasification furnace and the subsequent product gas conveying and treatment equipment or parts and the generation of temperature difference stress or fatigue damage are avoided. Meanwhile, part of solid powder, heavy oil vapor or fog drops and the like carried in the product gas are cooled, humidified, condensed and grown again, and returned to the bed layer for gasification reaction under the action of gravity.
Preferably, the feeding regulating valve, the cooling water regulating valve and the temperature measuring device are respectively connected through a singlechip and controlled by the singlechip. The temperature measuring device is used for measuring the temperature of the gasification furnace and transmitting signals to the singlechip, the singlechip controls the feeding regulating valve and the cooling water regulating valve, and the temperature of the gasification furnace upper part and the product air entering the product air outlet can be stably controlled by adjusting the quantity of the gasification raw materials with fluidity such as heavy oil entering the buffer bin and the cooling water entering the gasification furnace.
Preferably, the feeding spray heads and the cooling water spray heads are uniformly arranged at annular intervals. So that the heavy oil and other flowable gasification raw materials are distributed in the buffer bin and the cooling water is distributed more uniformly in the gasification furnace.
Preferably, the lower part of the bottom end of the feeding hole of the gasification furnace is sequentially communicated with a cone section and a lower cylinder, one end diameter of the cone section is larger than the diameter of the other end, the small diameter end of the cone section is connected with the feeding hole of the gasification furnace, and the large diameter end of the cone section is connected with the lower cylinder. Because the product gas outlet of the gasification furnace is higher than the bottom end of the feed inlet of the gasification furnace, namely, is higher than the joint of the lower cylinder body and the conical cylinder section, the product gas and dust particles rise together and firstly enter the annular channel between the lower cylinder body and the inner wall of the gasification furnace, when the product gas and the dust particles rise to the space between the conical cylinder section and the inner wall of the gasification furnace, the flow velocity is greatly reduced due to the increase of the section, and the dust particles fall under the action of self gravity and return to the bed layer along with the raw materials to participate in gasification reaction. On one hand, the dead time of raw materials in the gasification furnace is increased, so that the raw materials can fully react, and on the other hand, dust particles can be effectively separated from product gas, and the separation and purification cost of a subsequent process system is reduced.
Preferably, the outer wall of the lower cylinder is uniformly provided with dispersing plates along the radial direction of the lower cylinder at intervals, and the other ends of the dispersing plates are connected with the inner wall of the gasification furnace. In the process of rising the product gas and the dust particles together, the dust particles are concentrated along with the product gas to the direction of a product gas outlet, so that the dust particles close to the product gas outlet side have larger density, are unfavorable for falling and full reaction of the dust particles, the annular channel between the outer wall of the lower cylinder body and the inner wall of the gasification furnace is uniformly divided by the dispersing plate, and the product gas and the dust particles are uniformly dispersed in the channel formed by the dispersing plate in the process of rising together, thereby being favorable for full reaction and falling of the dust particles.
Preferably, a cooling water spray head is disposed above the area formed between each adjacent dispersing plate. The cooling water spray head can sufficiently cool the product gas in the area formed between each two adjacent dispersing plates, and the effect is better.
Compared with the prior art, the invention has at least one of the following beneficial effects: the invention ensures that the raw materials entering the gasification furnace are mixed more uniformly and can be adjusted in time, so that the upper part of the gasification furnace and the temperature of the product gas are controlled stably; the dead time of each raw material is long, so that the raw materials fully react; the upper part of the gasification furnace and the temperature of the product gas are quickly regulated and stabilized by cooling water, and meanwhile, part of solid powder, heavy oil steam or fog drops and the like carried in the product gas are cooled, humidified and condensed again to grow up, and return to a bed layer for gasification reaction under the action of gravity; the invention can automatically adjust the quantity of the gasification raw materials with fluidity such as heavy oil entering the buffer bin and the quantity of cooling water entering the gasification furnace, and the temperature of the product gas at the upper part of the gasification furnace and entering the product gas outlet can be stably controlled; according to the invention, on one hand, the dead time of raw materials in the gasification furnace is increased, so that the raw materials can fully react, and on the other hand, dust particles can be effectively separated from product gas, and the separation and purification cost of a subsequent process system is reduced; the dispersing plate uniformly divides the annular channel between the outer wall of the lower cylinder and the inner wall of the gasification furnace, and product gas and dust particles are uniformly dispersed in the channel formed by the dispersing plate in the rising process, so that the falling and full reaction of the dust particles are facilitated; the cooling water spray head can sufficiently cool the product gas in the area formed between each two adjacent dispersing plates, and has better effect.
