The garbage disposal is to rapidly remove the garbage, perform harmless treatment and finally reasonably utilize the garbage. The garbage disposal methods widely used today are sanitary landfills, high temperature composting and incineration. The purpose of garbage treatment is harmlessness, resource utilization and reduction.

And the waste incineration can achieve the effect of resource recycling, and steam generated by the heat generated by the incineration of the waste can drive a turbine generator to generate electricity. However, while there is concern about energy safety and climate change, the cost of disposing of waste is increasing worldwide, and these factors have increased the possibility of disposing of household waste in energy-intensive ways that have been used only for disposing of dangerous materials such as medical waste and asbestos. Therefore, the process of pyrolysis and gasification of garbage is developed by combining the current technical conditions to avoid secondary pollution. The garbage pyrolysis gasification is that the garbage is heated at high temperature in a closed chamber and is converted into synthesis gas, and the components of the synthesis gas are carbon monoxide and hydrogen. After filtration and chemical "cleaning" to remove toxic particles and gases, the fuel is burned to produce energy or converted to fuels such as methane, ethanol or synthetic diesel. Garbage vaporization can be used for quickly converting household garbage into energy, the garbage can be changed into assets from liabilities, and a clean energy source capable of being used on the spot is provided.

The existing garbage gasification process usually adopts a vertical gasification furnace structure as a main reactor, a series of reactions are achieved in the furnace through different reaction zones, finally, the discharged gas is treated to obtain synthesis gas, and the slag is also treated to be used as building filler. The inside in order to insulate against heat of present reactor, all be equipped with the fire prevention brick structure, because of the inside temperature of reaction zone can reach 1200 ℃, if direct transfer heat, can lead to jar body material to produce irreversible change because of the temperature is higher to influence the structural strength of whole jar body. Therefore, the heat is effectively isolated by arranging the fireproof brick wall structure. The existing fireproof brick is only directly attached to the inside of the tank body, namely a disposable structure is fixed, but now in practical use, the pressure of a reaction zone is about 2.7-8.5MPa, and the operating temperature can be suddenly increased to 1700 ℃. Under high temperature and high pressure, the refractory material in the combustion chamber can generate a corrosion phenomenon, and the refractory brick is continuously thinned by the scouring of heated gas and molten slag.

The reaction tower is generally of a vertical structure and comprises a plurality of layers from top to bottom, and the reaction tower is divided into areas according to internal temperature. The material enters the tank body from the top and then reacts differently with the change of temperature.

The uppermost part is a dry layer, the temperature of which is at 100-300 ℃, the temperature of the layer is increased in a gradient way, and the temperature is higher closer to the lower part. The layer generally dries the crushed garbage which just enters the tank body, and has large space, and occupies 10-20% of the whole tank body. But will generally be provided with means for pressing the material downwards in the feed, thereby providing a continuous pushing force downwards. The garbage entering the drying area is firstly contacted with the pyrolyzed fuel gas in the upper area and dehydrated within 2-4 hours, the exhaust port is communicated with the inside of the tank body in the area, and at the moment, the fuel gas mixed steam is exhausted from the exhaust port.

The lower part of the drying layer is a dry distillation layer, namely a cracking layer, the temperature of the drying layer is 300-600 ℃, the garbage dried by the upper layer gradually falls into the cracking layer, and is heated at the same time, so that a pyrolysis reaction is carried out, most of volatile components in the garbage are separated from solids, and when the temperature is close to the edge of 600 ℃, only ash residues are basically left in the garbage. In the dry distillation layer, a plurality of organic wastes generate alkanes, carbon monoxide, tar and water vapor, and meanwhile, some sulfur-containing and chlorine-containing substances generate a small amount of hydrogen chloride and hydrogen sulfide gas, and the hydrogen chloride and the hydrogen sulfide gas are discharged along with the water vapor and are treated by a subsequent desulfurization tower.

The lower part of the dry distillation layer is an oxidation layer, the temperature of the oxidation layer is about 600-1200 ℃, and most of heat is released by violent reaction of residual ash and air. However, because the amount of oxygen supplied is controlled so that the amount of oxygen is insufficient for complete reaction during the reaction, incomplete combustion occurs to produce carbon monoxide while heat is also released, and the maximum temperature of the oxidation zone may reach 1200 ℃.

The lower part of the oxidation zone is a reduction zone, oxygen does not exist in the reduction zone, carbon dioxide generated in the oxidation reaction is subjected to reduction reaction with carbon and water vapor to generate carbon monoxide (CO) and hydrogen (H)₂). Since the reduction reaction is endothermic, the temperature in the reduction zone is correspondingly reduced to about 600-800 ℃. Main production of reduction zoneThe substances are carbon monoxide (CO) and carbon dioxide (CO)₂) And hydrogen (H)₂). Gasification is virtually always combined with a dry cracking process of the fuel. In actual operation, the four regions have no definite boundaries, and are interpenetrating and interlaced. Therefore, at the outlet of the gasification furnace, the components of the produced gas are mainly carbon monoxide (CO) and carbon dioxide (CO)₂) Hydrogen (H)₂) Methane (CH)₄) Tar and small amounts of other hydrocarbons, as well as steam and small amounts of ash.

The reaction in the reduction zone is mainly as follows:

C+H₂O–CO+H₂

CO+H₂O–CO₂+H₂

C+CO₂–2CO

C+2H₂–CH₄

CO₂+H₂–2CO+H₂O

and the lower part of the final reduction area is a cooling area, the space occupation ratio of the cooling area is approximately the same as that of the feeding area, and residual slag in the cooling area can be discharged by a discharging mechanism. Meanwhile, in order to supplement the water vapor, the water vapor is injected into the bottom part at the same time, so that the conversion rate is improved.

The inside in order to insulate against heat of present reactor, all be equipped with the fire prevention brick structure, because of the inside temperature of reaction zone can reach 1200 ℃, if direct transfer heat, can lead to jar body material to produce irreversible change because of the temperature is higher to influence the structural strength of whole jar body. Therefore, the heat is effectively isolated by arranging the fireproof brick wall structure.

The existing fireproof brick is only directly attached to the inside of the tank body, namely a disposable structure is fixed, but now in practical use, the pressure of a reaction zone is about 2.7-8.5MPa, and the operating temperature can be suddenly increased to 1700 ℃. Under high temperature and high pressure, the refractory material in the combustion chamber can generate a corrosion phenomenon, and the refractory brick is continuously thinned by the scouring of heated gas and molten slag. The thinned part is generally concentrated on the upper part of the highest temperature layer of the reaction zone, in some cases, the firebrick can fall off due to the defect of bricking, the surface temperature of the wall of the gasifier tank rises when the incandescent gas invades the outside through a brick joint, the structural strength is reduced, and the deformation is generated due to stress, so that the possibility is high.

Therefore, the tank body needs to be checked in real time, and if the tank body falls off or becomes thin, the tank body needs to be maintained in time, so that major production safety accidents are avoided. And the utility model discloses a modularization mounting structure optimizes to the fire prevention module with single fire prevention brick, fixes through frame construction to improve the installation, dismantle and change efficiency.

Furthermore, the checkpost is forked tail strip structure, and it inserts one section tip of resistant firebrick is equipped with the expansion end, resistant firebrick realizes fixing with its expansion end parcel.

The firebrick is an integrated structure formed by sintering refractory materials and is used as a main fireproof material. The fixing strip is fixed on the inner wall of the tank body and used for fixing refractory bricks, a special clamping groove is formed in the fixing strip, and a clamp matched with the clamping groove is arranged on the refractory bricks and is of a cuboid-like structure.

The clip is a separate component, one end of the clip is inserted into the refractory brick and is fixedly connected with the refractory brick, and once the refractory brick is crushed, the clip can be directly taken down for recycling. That is to say, if need change some resistant firebricks, can directly break up the resistant firebrick that corresponds the position, then take off the checkpost to correspond new resistant firebrick and put into, pour into inorganic high temperature glue into around it again and seal, thereby accomplish the change work.

Through the arrangement of the fixing strip structure, a certain space can be reserved between the fireproof module and the inner wall of the tank body, after actual detection, the temperature in the space is 150-.

It is worth explaining that the firebrick is an arc-shaped block structure, four sides about from top to bottom, and during the installation, the terminal surface of two piece adjacent firebricks from top to bottom bonds through inorganic high temperature glue, and control two and have certain clearance between the firebrick that belongs to a ring fireproof wall, because of the firebrick is the arc structure during the installation, then and the outer lane diameter is greater than the inner circle diameter, outside promotion was installed from inside during the installation, so reserve certain clearance, avoid causing the installation and block. And a high-viscosity inorganic high-temperature adhesive is coated between the gaps for sealing. The inorganic high-temperature adhesive is a material special for bonding refractory materials and can keep a stable state at the working temperature of 0-2000 ℃.

Furthermore, when the refractory brick is installed on the fixed frame, a high-temperature adhesive is arranged between the clamp and the clamping groove.

Furthermore, glue injection openings communicated with the glue overflow grooves on the corresponding side are respectively arranged on the two sides of the glue overflow grooves close to the two sides on the inner concave surface of the refractory brick.

Because two adjacent resistant firebricks from top to bottom can be terminal surface laminating about the installation, the injecting glue is difficult when the installation, then is provided with excessive gluey groove structure to be equipped with the injecting glue mouth rather than the intercommunication at the surface, so that when installing and sealing up after the position, inject into inorganic high temperature through the high pressure and glue and seal, then improve the installation effectiveness, improve simultaneously sealed effect, compare in current from last to the mode of building a wall down, through the utility model discloses a mode can improve installation and dismantlement efficiency is built to the modularization.

Furthermore, the high-temperature sensor is fixed outside the tank body, and a section of the detection head of the high-temperature sensor penetrates through the tank body and is inserted into the corresponding refractory brick; an annular cover used for shielding is arranged outside the tank body aiming at all the high-temperature sensors on the single-layer fireproof ring.

Because the position that local resistant firebrick drops is random, the event needs to carry out temperature monitoring to every fire prevention module to the resistant firebrick structure change in the strict control ware inside prevents because of the gas leakage that the abrupt change leads to, thereby causes great potential safety hazard. The high temperature sensor is an S-shaped thermocouple with the detection range of 0-1800 ℃, and the detection point of the S-shaped thermocouple is inserted into the refractory brick.

When the outer side of the refractory brick falls off and the thickness is reduced to be less than 40% of the original thickness, the whole block easily falls off, so that the insertion depth of the detection end part of the S-shaped thermocouple is about 20-40%. The detection temperature is in the range of 400-800 ℃ at ordinary times, and the alarm is given out once the temperature exceeds 850 ℃ for more than 20min, or the alarm is directly given out when the temperature exceeds 950 ℃ within 20min after the temperature is recorded to exceed 850 ℃ for the first time. The monitoring system can warn in various ways, including but not limited to sound and light, and if the manager is not nearby and no person is on duty, the monitoring system can be set to send remote information to the terminal equipment for warning.

Furthermore, the fireproof rings at the top and the bottom of the fireproof brick wall are connected with fireproof rings for arc transition, and each fireproof ring comprises a plurality of flow guide blocks connected with the end face of one side of the fireproof brick wall provided with the glue overflow groove.

The utility model has the advantages that:
