Description

Technical Field

[0001] The utility model belongs to the technical field of gasifier test, and particularly relates to an anti-biased burning device for a low-carbon raw material gasifier test device. Background Art

[0002] In the existing low-carbon raw material gasification furnace test device, i.e., the low-carbon raw material gasification pilot test device, the raw material needs to enter the gasifier through the sleeve through the gasifier top cover. In order not to affect the feeding of the gasifier, the gasification gas outlet generated by the gasifier is generally located at the upper side wall of the gasifier. During normal operation, the gasifier produces a large amount of gas and the temperature is high (about 400°C). Since the gasifier test device is small in shape, long-term operation will cause the temperature of the upper part of the gasifier near the gasification gas outlet to be high, and the temperature of the upper part of the gasifier away from the gasification gas outlet to be low, which will cause the gasifier to burn unevenly, affecting the stable operation of the gasification device.

[0003] The above-mentioned low-carbon raw materials mainly include domestic dry garbage, agricultural and forestry waste, and crop straw. Utility Model Content

[0004] The utility model aims to provide an anti-biased burning device for a low-carbon raw material gasification furnace test device, which can balance the air temperature at the upper part of the gasification furnace test device.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is an anti-biased burning device for a low-carbon raw material gasification furnace test device, comprising an air outlet pipe and an air inlet component.

[0006] The gas outlet pipe is fixed to the gasification gas outlet of the gasifier test device; the diameter of the gas outlet pipe is greater than or equal to the diameter of the gasification gas outlet; the gas inlet component is horizontally arranged between the sleeve and the inner wall of the gasifier, and one side of the gas inlet component is connected to the gas outlet pipe; the gas inlet component is used to extend the gas outlet distance of the gasification gas at the upper part of the gasifier;

[0007] Preferably, the air inlet component is an annular tube; the annular tube is connected to the air outlet pipe, and a plurality of air inlets are provided at the bottom of the annular tube.

[0008] Preferably, the air inlet component is an arc-shaped tube; the middle portion of the arc-shaped tube is connected to the air outlet pipe, and both ends of the arc-shaped tube are open.

[0009] Preferably, the arc length of the arc tube is greater than or equal to a semicircle.

[0010] The utility model discloses an anti-biased burning device for a low-carbon raw material gasification furnace test device, which has the following advantages compared with the prior art:

[0011] (1) The air inlet component can effectively extend the gas outlet distance of the gas generated by gasification in the upper part of the gasifier, so that the temperature in the upper part of the gasifier is balanced and the gasifier is prevented from burning unevenly;

[0020] The air intake component 3 is an annular tube 31; the annular tube 31 is connected to the air outlet pipe 2, and a plurality of air inlets 32 are provided at the bottom of the annular tube 31, and the annular tube 31 is horizontally sleeved between the sleeve 13 and the inner wall 11 of the gasifier, wherein the annular tube 31 can be fixed to the inner wall 11 of the gasifier by a bracket, and the gasification gas at the upper part of the gasifier passes through the plurality of air inlets 32, enters the annular tube 31, passes through the air outlet pipe 2, and then enters the gasification gas outlet 11, and the gasification gas at the upper part of the gasifier can be evenly distributed through the annular tube 31 to prevent uneven burning of the gasifier.

[0023] Compared with Example 1, the arc tube 4 is convenient to install in the gasifier and saves materials.
