Description

Technical Field

[0001] The utility model relates to the field of incinerators, and more specifically to a heat storage type thermal incinerator based on a novel explosion relief structure. Background Art

[0002] During the operation of a regenerative thermal incinerator, excessive pressure may accumulate inside the equipment due to the high temperature and pressure changes generated by combustion. By setting up an explosion relief structure, the overpressure gas generated inside the furnace body can be quickly released, so that the pressure inside the furnace body returns to normal, avoiding explosions or other serious accidents caused by the equipment, ensuring the safety of the equipment and operators, extending the life of the equipment, and reducing maintenance costs.

[0003] The explosion relief structure of the existing heat storage thermal incinerator is composed of a wire mesh, a bracket, an insulation unit, an explosion relief membrane, etc. As the incinerator runs for a long time and is baked by high-temperature exhaust gas for a long time, the wire mesh is easily deformed by heat, causing the insulation unit to be misaligned and produce gaps. In addition, the wire mesh will melt and break under high temperature for a long time, and the insulation unit will become loose or even fall off, posing a huge installation hazard. Some explosion relief membranes also have poor fixing effects, which will affect the explosion relief process of the explosion relief membrane, resulting in unsatisfactory explosion relief effects. In addition, some explosion relief membranes are easily affected by the external environment and may rupture, age or be damaged prematurely, resulting in reduced safety performance. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provides a heat storage type thermal incinerator based on a novel explosion relief structure.

[0006] Furthermore, the thermal insulation unit is made of aluminum silicate material.

[0007] It has good high temperature resistance and heat insulation performance, can maintain structural stability in high temperature environment, and can effectively reduce heat conduction, prevent the heat energy inside the furnace from being transferred to the outside, and improve the thermal utilization rate of the incinerator.

[0008] Furthermore, the explosion relief unit further comprises a backing plate and a fixing plate, and the backing plate and the fixing plate clamp the explosion relief membrane to fix the explosion relief membrane; the explosion relief unit is fixedly installed at the furnace body.

[0009] Through the clamping action of the backing plate and the fixing plate, the explosion-relief membrane can be effectively fixed, thereby ensuring the normal operation of the explosion-relief unit.

[0010] Furthermore, the fixing plate and the pad are both in the shape of a rectangular frame.

[0011] Thereby, it has better structural stability and can effectively support and fix the explosion-proof membrane.

[0012] Furthermore, the cross-section of the explosion vent includes an upper rectangular portion and a lower rectangular portion located below the upper rectangular portion; the upper rectangular portion has a height of 265 mm and a width of 400 mm; the lower rectangular portion has a height of 175 mm and a width of 300 mm.

[0013] The T-shaped structure can provide sufficient support and stability, and can form a good sealing effect when the explosion vent is closed, ensuring safe and stable operation under high pressure or high temperature environment.

[0014] The present application also discloses a heat storage thermal incinerator based on a novel explosion-proof structure, comprising a furnace body, an insulation unit and an explosion-proof unit, wherein the furnace body has an explosion-proof opening, and the cross-section of the explosion-proof opening is T-shaped; the insulation unit is filled in the explosion-proof opening, and the cross-section of the insulation unit is T-shaped; the explosion-proof unit comprises a pad, a fixing plate, an explosion-proof membrane between the pad and the fixing plate, and a protective plate fixedly connected to the fixing plate and located above the fixing plate, the protective plate having a cross-shaped through groove and four strip-shaped grooves to divide the protective plate into a rectangular frame-shaped mounting plate and four triangular plates connected to the mounting plate, the mounting plate having four first anchor points, the triangular plate having a second anchor point, the four first anchor points and the four second anchor points corresponding one to one, and the corresponding first anchor points and second anchor points being connected by connecting ropes.

[0015] The protection plate protects the explosion-proof membrane. When the internal pressure is too large and the explosion is vented, the triangular plate can be broken off from the strip groove, so as not to affect the explosion-proof membrane rupture and venting, and the broken triangular plate is connected to the pull rope to limit the position and will not fly around, thereby improving safety.

[0016] Furthermore, the first anchor point and the second anchor point are both semicircular rings.

[0017] Thus, the semicircular ring can provide good support and fixation, making the connection of the connecting rope more secure.

[0018] Furthermore, the fixing plate and the furnace body are fixed by a plurality of first bolts; and the protection plate and the fixing plate are fixed by a plurality of second bolts.

[0019] The first bolt is used to fix the connection between the plate and the furnace body, ensuring a firm connection between the explosion relief unit and the furnace body, and the second bolt is used to fix the connection between the protection plate and the fixed plate, further enhancing the stability and safety of the explosion relief unit.

[0020] Furthermore, the thermal insulation unit is made of aluminum silicate material.

[0023] 2. The incinerator of the present application clamps the explosion-venting membrane by means of a pad and a fixing plate, thereby stably fixing the explosion-venting membrane. The stable fixation of the explosion-venting membrane can ensure that when an explosion occurs, the explosion-venting membrane can rupture quickly and accurately to release the internal pressure and achieve the expected explosion-venting effect.

[0024] 3. The incinerator of the present application is provided with a protective plate, so that the protective plate protects the explosion-proof membrane, and when the explosion is vented, the triangular plate can be broken from the strip groove, so as not to affect the explosion-proof membrane.
