Embodiment 1

[0016] Embodiment 1, with reference to figure 1 , a fully enclosed flue gas circulation system for a straw gasification stove, comprising a straw gasification stove 14, a water jacket 1 is provided on the furnace body of the straw gasification stove 14, the water jacket 1 and a heating device 3 Connected; the gas outlet of the straw gasification stove 14 is connected to the tar treatment device 17 in turn, sealed through the air cooling device 18, connected to the filter device 19 and the phoenix induction device 20, and then enters the combustion chamber 6 of the combustion device. The flue gas circulation system includes two closed circulation systems, one is the closed circulation system of the flue gas generated when the straw gasification stove is started, and the other is the closed circulation system of the flue gas generated by the combustion of the combustion device; the smoke generated by the combustion of the combustion device The closed circulation system of gas is...

Embodiment 2

[0019] Embodiment 2, a fully enclosed flue gas circulation system of a straw gasification furnace, the furnace core 5 is evenly distributed with ventilation pipes 21, through which the upper and lower parts of the furnace chamber of the combustion device are connected. The rest are the same as embodiment 1. When the flue gas generated by the combustion of fuel gas in the combustion chamber 6 of the combustion device (stove) rises to the space between its upper part and the top of the furnace chamber through the ventilation pipes 21 in the furnace core 5, the upward flue gas is The space is blocked so that the flue gas cannot go upwards, and then descends to the flue gas outlet 23 at the bottom of the return water jacket 4 through the space formed by the outer wall of the furnace core 5 and the inner wall of the return water jacket 4 for recycling. The evenly distributed ventilation pipes 21 in the furnace core 5 enable the high-temperature flue gas to quickly and evenly heat t...

Embodiment 3

[0020] Example 3, a fully enclosed flue gas circulation system of a straw gasification stove, the water jacket 1 on the furnace body of the straw gasification stove is connected to a heating device 3, and the outlet of the heating device 3 is connected to a two-way water circulation system One way is for the outlet of the heating device 3 to be in sealing communication with the water jacket 4 on the furnace body of the combustion device, and the outlet of the water jacket 4 is in sealing communication with the water jacket 1 on the furnace body of the straw gasification furnace; the other is for the heating device 3 The outlet of the furnace core 5 is sealed and communicated with the water jacket 4 on the furnace body of the combustion device, and the water jacket 4 is sealed and communicated with the furnace core 5 in the furnace chamber of the combustion device. The above two return water circulation systems form a complementary hot water heating system and make full use of t...

Abstract

A totally-enclosed flue gas circulation system of a straw gasification stove comprises two enclosed circulation systems; one is the enclosed circulation system for a flue gas produced at the starting of the straw gasification stove and the other is the enclosed circulation system for the flue gas produced by the combustion of a combustion device. Greenhouse gases such as carbon dioxide in the flue gas is delivered to a gasification zone in the straw gasification stove or a combustion chamber in the combustion device (stove) and is converted into carbon monoxide at high temperature condition; the heat is released after combustion and the thermal energy utilization rates of carbon, hydrogen and oxygen are greatly improved; a self-closed and circulated clean production system is formed and the purpose of energy conservation and emission reduction is achieved.

Description

technical field [0001] The invention relates to a straw gasification furnace, in particular to a fully enclosed flue gas circulation system of the straw gasification furnace, and also to a water circulation system of the straw gasification furnace. Background technique [0002] At present, the straw gasification stoves on the market are exhausted through the chimney, and emit greenhouse gases such as carbon dioxide and harmful substances such as sulfur dioxide and nitrogen oxides into the atmosphere, polluting the atmosphere, causing population concentration and industrial pollution. The cities and villages in the developed areas have more and more smoggy weather, which seriously damages the health of the people. At the same time, part of the heat energy is lost in vain during the smoke exhaust process, which increases the consumption of fuel and increases the cost of production and living. Contents of the invention [0003] The invention provides a fully-enclosed flue ga...
