Description
Technical Field
The invention relates to a garbage incinerator, in particular to a mechanical grate type garbage incinerator with a variable reverse-pushing grate angle for incinerating general industrial wastes.
Background
GB18485-2014 standards for controlling the incineration pollution of the domestic garbage stipulate that the following wastes can also directly enter a domestic garbage incinerator for incineration disposal besides mixed domestic garbage:
general industrial solid wastes produced by industries for clothes processing, food processing and other services for urban life, collected by environmental health agencies, having properties similar to those of domestic wastes; oversize products produced in the screening process in the domestic garbage composting treatment process and solid residual components produced in other biochemical treatment processes; infectious waste in the medical waste classification catalogue which is subjected to fragmentation, destruction and disinfection treatment according to the requirements of HJ/T228, HJ/T229 and HJ/T276 and meets the disinfection effect test index.
The domestic garbage incinerator is divided into four types according to different combustion modes: the mechanical grate type domestic garbage incinerator of the stratified combustion; fluidized bed type domestic garbage incinerator with boiling combustion; a rotary kiln type domestic garbage incinerator for rotary combustion; other incinerators of other combustion.
Because the mechanical grate type domestic garbage incinerator does not have the problems of large fly ash amount, bad production environment and the like caused by the fact that pretreatment is needed like a fluidized bed type domestic garbage incinerator, the difficult problems of blockage faults of a garbage inlet and an outlet and the like which are difficult to solve by a rotary kiln type domestic garbage incinerator can be avoided, the mechanical grate type domestic garbage incinerator has the characteristics of mature, stable and reliable operation and the like, and becomes a preferred incinerator type for incinerating general industrial wastes.
The common industrial wastes have the characteristics of batch property, intermittent property, mixing property and the like due to different generated channels, the characteristics (including components, heat value, ash and the like) of the industrial wastes have great difference, and a conventional mechanical grate type domestic garbage incinerator (the inclination angle of a reverse pushing grate of the incinerator is constant) cannot adapt to the industrial wastes and needs to be improved in adaptability; however, how to improve is the key to solve the technical problem.
Disclosure of Invention
The invention aims to overcome the defects in the background technology and provide the common industrial waste incinerator with the variable reverse-pushing grate angle, which can adapt to different characteristics of common industrial waste and has the characteristics of good combustion effect, simple structure and cost saving.
The technical scheme provided by the invention is as follows:
a common industrial waste incinerator with variable reverse-pushing grate angle comprises a furnace body with a charging chute, a feeder arranged in the furnace body, a grate, an air chamber and an ash discharge chamber positioned below the grate, a slag discharging machine and a slag discharging channel; the grate is sequentially divided into a front section and a rear section along the garbage running direction, the front section close to the charging chute is a reverse-push type grate for preheating, drying and burning, the rear section is a downward-inclined forward-push type grate for burning, and a height drop is arranged at the joint of the front section of the grate and the rear section of the grate; the method is characterized in that:
the reverse-push type grate is a variable-angle reverse-push type grate, and the front end and the rear end of the grate frame are respectively hinged with the first supporting column and the second supporting column and are supported by the two supporting columns; the upper part of the first support column is a linear motion mechanism which is vertically arranged and hinged with the front end of the fire grate frame, so that the inclination angle of the fire grate frame and the horizontal plane is changed through the vertical up-and-down motion of the front end of the fire grate frame; the bottom end of the second support column can be horizontally movably positioned on the terrace through a horizontal moving mechanism, so that when the front end of the fire grate frame vertically moves up and down, the second support column can provide an adjusting space required by the movement of the rear end of the fire grate frame in the horizontal direction.
The linear motion mechanism is a hydraulic cylinder driven by a hydraulic power mechanism.
The horizontal moving mechanism is a crawler-type sliding plate and comprises a plurality of crawler wheels and a crawler chain ring, wherein the crawler wheels are rotatably positioned at the bottom ends of the second supporting columns through supports, the crawler chain ring is formed by connecting a plurality of crawler plates, covers the crawler wheels and is meshed with the crawler wheels. The crawler-type sliding plate can reduce the pressure on the terrace and prolong the service life of the surface of the terrace.
The reverse-pushing type two-section grate is arranged on a frame which is obliquely arranged and can change angles, and the inclination angle of the reverse-pushing type two-section grate and the horizontal plane is 15-30 degrees.
Furthermore, a transition structure is arranged at the joint of the forward-pushing fire grate and the backward-pushing fire grate to ensure that the incinerated substances are conveyed from the backward-pushing fire grate to the forward-pushing fire grate without omission; in the transition structure, the rear end of a cover plate is arranged at the front end of the forward-pushing fire grate, the bottom surface of the front part of the cover plate is lapped on round steel at the rear end of the reverse-pushing fire grate, and the front end of the cover plate is kept away from the reverse-pushing fire grate.
Furthermore, the furnace body is provided with two layers of secondary air injection devices, and the temperature and the flow of the secondary air of each layer can be adjusted to adapt to the characteristics of different general industrial wastes such as heat values, ash content and the like, so that the proper hearth temperature and the combustion working condition are formed.
The working principle of the invention is as follows: because the first support column cannot slide left and right, when the hydraulic cylinder is contracted, the angle for supporting and reversely pushing the grate is reduced, and the second support column behind is pushed to slide backwards (rightwards); when the hydraulic cylinder extends, the angle of the support reverse pushing fire grate is increased, and the second support column behind is pushed to slide forwards (leftwards). When the hydraulic cylinder and the sliding distance reach the required distance, the frame can be connected, the related beam can be fixed, and the reverse thrust inclination angle can be determined so as to adapt to the characteristics of heat value, ash content and the like of certain common industrial wastes.
The invention has the beneficial effects that:
according to the invention, the hinge point at the rear end of the grate frame is taken as a reference point, the vertical height of the hinge point at the front end of the grate frame is changed through the up-and-down extension of the hydraulic cylinder, and the first support column cannot move horizontally, the second support column can slide horizontally and the beam is matched, so that the purpose of adjusting the inclination angle of the reverse pushing grate frame is successfully achieved; the two-layer secondary air injection device that sets up simultaneously can adapt to the different combustion operating modes that general industrial waste appears because of characteristics such as different composition, calorific value, ash content in the incineration process, guarantees that industrial waste burns fully to make the pollutant emission that incineration technology waste produced reach minimumly. In addition, the forward-pushing fire grate is fixed at 10 degrees, so that the structure of the incinerator can be simplified, and the cost is saved. The combination part is arranged between the backward pushing part and the forward pushing part, and the change of different inclination angles of the backward pushing part can be adapted only by changing the angle of the cover plate.

Detailed Description
The heat value of the garbage fed into the conventional mechanical grate type household garbage incinerator is usually 1000-2000 Kcal/kg, the inclination angle of the reverse-push grate is fixed at about 25 degrees, and the heat value of the household garbage can be controlled by adjusting the speed of the grate within the conventional variation range. In addition, the inventor finds out in a large number of experiments that the angle of the forward-pushing grate is changed: the inclination angle of the fire grate directly influences the retention time of the garbage in the furnace, thereby determining the combustion condition of the garbage, the thermal ignition loss rate of the slag after the garbage is combusted and the like.
Based on the above findings, the present invention provides the following technical solutions.
The common industrial waste incinerator with the variable reverse-pushing grate angle is a mechanical grate type waste incinerator, and comprises a furnace body 8 with a charging chute 1, a feeder arranged in the furnace body, a grate, an air chamber and an ash discharge chamber 5 positioned below the grate, a slag discharging machine 13 and a slag discharging channel 6; the fire grate is divided into a front section and a rear section in sequence along the garbage running direction, the front section close to the charging chute is a reverse-push type fire grate 3 for preheating, drying and burning, the rear section is a downward-inclined forward-push type fire grate 4 for burning, and the front section and the rear section of the fire grate are provided with height drop at the joint (joint part) of each other.
The reverse-push type grate is of a conventional two-section driving structure, the driving mechanism is arranged below the reverse-push type grate and comprises a reverse-push type grate driving frame, a reverse-push type grate driving hydraulic cylinder and a reverse-push type grate driving connecting piece for connecting the reverse-push type grate driving hydraulic cylinder and the reverse-push type grate driving hydraulic cylinder, the reverse-push type grate driving hydraulic cylinder is positioned outside the air chamber, and a sealing structure is arranged between the driving connecting piece and the air chamber.
According to the recommendation of the two-section type domestic garbage incinerator with the adjustable material layer in the Chinese patent ZL200610052844.6, the forward-pushing fire grate is obliquely arranged, and the inclination angle of the forward-pushing fire grate and the horizontal direction is fixed to be 10 degrees. The angle is tested by long-term practice and is an engineering practical conclusion obtained after the inventor tests the forward-pushing grate for a plurality of times between 0 and 25 degrees. The angle of the forward-pushing fire grate is fixed, so that the structure can be simplified, and the cost is saved.
The above are all the structures of the conventional garbage incinerator.
The improvement of the invention is that:
the reverse-push type grate is a variable-angle reverse-push type grate, the front end and the rear end of a grate frame are respectively hinged with a first supporting column 10 and a second supporting column 11 (a hinged point J1 of the first supporting column and a hinged point J2 of the second supporting column; the hinged axes are both vertical to the paper surface of the attached drawing) and are supported by the two supporting columns; the upper part of the first support column is a linear motion mechanism which is vertically arranged and hinged with the front end of the fire grate frame, so that the inclination angle of the fire grate frame and the horizontal plane is changed through the vertical up-and-down motion of the front end of the fire grate frame; the bottom end of the second support column is horizontally movably (i.e. in the left-right direction shown in fig. 1 and 2) positioned on the terrace through a horizontal moving mechanism, so that when the front end of the fire grate frame moves vertically up and down, the second support column can provide a regulating space required for the rear end of the fire grate frame to move in the horizontal direction.
As can be seen by comparing fig. 1 and 2: the minimum inclination angle of the grate frame and the horizontal plane is a2, and the maximum inclination angle of the grate frame and the horizontal plane is a1, so that the swinging angle of the grate frame in the inclination adjusting process is a1-a 2; during this period, the front end hinge point J1 of the grate frame has a height extension distance H, and the rear end hinge point J2 of the grate frame has a travel distance B (i.e., the travel distance of the second support post). These data may be determined according to specific design requirements. In addition, when the hinge point J1 at the front end of the grate frame is at the highest position, the front end (left end in the figure) of the reverse-push type grate should not be higher than the position of the connection end 2 at the back of the feeding platform (and should be covered by the transition plate 14 of the feeding platform) to ensure the smooth transportation of the object to be incinerated.
Preferably, the linear motion mechanism is a hydraulic cylinder (or a screw mechanism driven by a motor) driven by a hydraulic power mechanism. The hydraulic system formed by the hydraulic power mechanism and the hydraulic cylinder is of a conventional structure and is not described in detail herein.
The horizontal moving mechanism is a crawler-type sliding plate; the crawler belt comprises a plurality of crawler wheels and a crawler chain ring, wherein the plurality of crawler wheels are rotatably positioned at the bottom ends of the second support columns through supports, and the crawler chain ring is formed by connecting a plurality of crawler plates, covers the crawler wheels and is meshed with the crawler wheels.
The reverse-push type two-section grate is arranged on a frame which is obliquely arranged and can change angles, and the inclination angle between the reverse-push type two-section grate and the horizontal plane is recommended to be 15-30 degrees.
Because the reverse-pushing grate can swing around the axis of the hinge point J2 as required, the relative position between the reverse-pushing grate and the forward-pushing grate (the joint) can be slightly changed. For this purpose, the joining can be carried out using a thermal expansion structure (zl201410850122.x) owned by the applicant as a transition structure. As shown in fig. 6, round steel 16 is fixed at the rear end of the reverse-push type grate, the rear end of a cover plate 15 is inserted into the front end of the forward-push type grate, the bottom surface of the front part of the cover plate is covered on the round steel 16 (the axis of the round steel is vertical to the paper surface), and the front end of the cover plate is kept away from the reverse-push type grate; when the reverse-push type fire grate swings, an angle b between the cover plate and a straight line 17 (a connecting line of a first hinge point and a second hinge point) can be slightly changed; because the forward-pushing fire grate is fixed, the change of different inclination angles of the backward-pushing fire grate can be adapted only by adjusting the shape and the angle of the cover plate.
In addition, the secondary air arrangement is adjusted, the middle part of the furnace body is provided with two layers of secondary air injection devices (conventional structures), and the proper hearth temperature and the combustion working condition are formed by adjusting the temperature and the flow of the secondary air, so that the secondary air injection furnace is suitable for the heat value and the ash content characteristics of different types of common industrial wastes. The two-layer secondary air injection device comprises an upper secondary air injection pipe 9-1, a lower secondary air injection pipe 9-2 and a fan for supplying air to the two injection pipes through air pipes.
