节能高效的热解锅炉

Abstract

一种节能高效的热解锅炉，包括锅体，位于锅体上方的第一侧的投料口，位于锅体下方的第二侧的料渣出口，位于锅体上方的第三侧的热解气出口，至少部分的位于锅体下方的加热炉，加热炉用于为锅体供热、将锅体内部的物料加热以促使其分解为热解气和料渣，其特征在于：多个导热管，沿一定角度横向穿过锅体上的多个导热管洞口，至少使热解气能够通过多个导热管向锅体内部输送热量。依照本实用新型的节能高效的热解锅炉，通过将炉灶燃烧时产生的高热废气在密闭的环境中通过导热管贯穿锅体，使内部物料也能均匀受热，提高废气热量利用率同时，加快物料热解效率，减少料渣中不充分热解的物料含量。

Claims

1. An energy-efficient pyrolysis boiler, comprising a boiler body, a feeding port on a first side above the boiler body, a slag outlet on a second side below the boiler body, a pyrolysis gas outlet on a third side above the boiler body, and a heating furnace at least partially located below the boiler body, the heating furnace being used to heat the boiler body and heat the materials inside the boiler body to promote their decomposition into pyrolysis gas and slag, characterized in that: Multiple heat-conducting pipes pass laterally through multiple heat-conducting pipe openings on the pot body at a certain angle, so that the pyrolysis gas can transfer heat into the pot body through multiple heat-conducting pipes.

2. The pyrolysis boiler according to claim 1, characterized in that: Multiple heat pipes are arranged in a diagonal grid pattern, at an angle of 10-30 degrees to the horizontal plane of the pot body, and run through the entire pot body.

3. The pyrolysis boiler according to claim 1, characterized in that: There is also a pressure sensor and valve between the heating furnace and the pyrolysis gas outlet. The valve includes a pressure regulating valve and an external gas valve. After the pressure of the combustible gas generated after the material is pyrolyzed reaches the gas supply pressure threshold, it is sent into the heating furnace for combustion through the pressure sensor and the pressure regulating valve. When the gas pressure decreases to the alarm threshold, the external gas valve is opened. When the gas pressure further decreases to the shutdown threshold, the external gas valve is closed to maintain the combustion state until all the pyrolysis gas is burned out, and all valves are closed to shut off the fire.

4. The pyrolysis boiler of claim 1, wherein: At least one pot wing, distributed in a ring at the outer edge of the upper part of the pot body, guides at least the pyrolysis gas into multiple heat pipes.

5. The pyrolysis boiler according to claim 4, characterized in that: The fins are distributed in a ring on the outer surface of the upper half of the pot body. Their thickness or height gradually decreases from the center to the periphery, and the bottom is horizontal or sloping downwards.

6. The pyrolysis boiler of claim 1, wherein: The heating furnace includes a heating structure, a supporting structure, an electric ignition system, and a gas supply system.

7. The pyrolysis boiler according to claim 6, characterized in that: The heating structure includes a bottom heating plate and at least two side heating rings. The bottom heating plate is located at the bottom of the pot body, and the side heating rings are located on the outer surface of the lower part of the pot body. The support structure consists of a bottom pad and side ring pillars. The bottom pad is used to support the bottom heating plate, and the side ring pillars are used to support the side heating rings.

8. The pyrolysis boiler according to claim 7, characterized in that: The gas transmission system includes two sets of square tubes to respectively transport pyrolysis gas, external gas, and combustion-supporting gas. The upper set supplies gas to the bottom heating plate, and the lower set supplies gas to the side heating ring.

9. The pyrolysis boiler of claim 7, wherein: On the gas loop of the side heating ring, starting from the nearest gas outlet point, at a 90-degree angle, an ignition head is installed and wrapped with an ignition head protective sleeve.

10. The pyrolysis boiler of claim 7, wherein: The protective cover is wrapped with heat-insulating rock wool inside, with a thickness of 20mm, and wrapped with heat-resistant 1Cr5Mo steel outside, with a thickness of 2mm.
