Embodiment Construction

[0022] Such as figure 1 As shown, the present invention provides a steam injection device for a biomass gasifier, the device includes an upper hanging pan 1, a lower hanging pan 2, a steam pipeline 3 and a steam nozzle 4 communicating with the steam pipeline, the upper hanging pan and the lower hanging pan. The hanging pans are equal in size and have the same structure, and they are all circular pans. The circular pans are evenly provided with feeding holes 1-1, 2-1. The lower hanging pans are fixedly installed, and the upper hanging pans are connected with a rotating handle 5 to make the upper hanging pans Rotate freely within 36 degrees, and a plurality of steam nozzles and temperature control probes 6 are installed on the bottom surface of the upper hanging pan and the top of the lower hanging pan.

[0023] Such as figure 1 As shown, the upper hanging plate and the lower hanging plate are connected with a circulating cooling water pipeline 7.

Abstract

The invention discloses a steam spraying device of a biomass gasification furnace. The device comprises an upper hanging scaffold, a lower hanging scaffold, a steam pipeline and steam nozzles which are communicated with the steam pipeline, wherein the upper hanging scaffold and the lower hanging scaffold are the same in size and structure and are circular discs; material discharging holes are uniformly distributed on each circular disc; the lower hanging scaffold is fixedly arranged and the upper hanging scaffold is connected with a rotary handle to freely rotate the upper hanging scaffold within a range of 36 degrees; and the bottom face of the upper hanging scaffold and the upper side of the lower hanging scaffold are provided with a plurality of the steam nozzles and a temperature control probe. The steam spraying device of the biomass gasification furnace is mounted in a low-suction type gasification furnace, is used for injecting water steam in straw combustion and gasification processes, and is provided with a temperature control device, thus the purpose of spraying certain amount of steam while setting the temperature can be achieved, the operation is convenient and simple, and the steam spraying device is very suitable to be used in operation of straw gasification furnaces.

Description

technical field [0001] The invention relates to a device for injecting steam into a biomass gasification furnace. Background technique [0002] The calorific value of combustible gas per cubic meter of corn straw is 5327.7KJ / M 3 , the calorific value of the gas after the downdraft gasifier is 4808.8KJ / M 3 , other contents are as follows: [0003] [0004] In the process of using straw gas, people find that the efficiency of straw gas is very slow in cooking, cooking, heating, and wall-hung boiler heating. Due to its low calorific value, it takes a long time. Therefore, how to increase the calorific value of straw gas is an urgent need A problem solved. [0005] The main four gasification processes of straw gasification furnace are analyzed as follows: [0006] Drying process: After the biomass enters the gasifier, under the action of heat, the surface moisture is precipitated. The main drying stage is at 200-300°C. [0007] Pyrolysis reaction: When the temperature r...
