Description
Technical field
The invention belongs to the coal burning equipment technical field, specifically is a kind of twin furnace body coal gasification furnace that uses in parallel.
Background technology
In the prior art, the structure of coal gasification furnace mostly enters in the body of heater by water vapour and the air mixed that produces in the body of heater, generates CO, H under certain condition
2And CH
4Deng inflammable gas.As the disclosed patent No. of Chinese patent is that a kind of self-balanced coal continuous gasification furnace of 02135743.9 also designs by this structural principle, though realized coal gasification furnace successive operation purpose, but structure is comparatively complicated, vapour generator complex structure in the burner hearth, vapour pipe separates setting with gas pipe, thermal transition efficient is subjected to certain limitation, and gas yield is lower.
Summary of the invention
The present invention is directed to the vapour generator complex structure that exists in the prior art, air feed continuously during coal, vapour pipe separates the drawback that is provided with gas pipe, provide a kind of by the combination in parallel of a plurality of at least two bodies of heater, the coal gasification furnace of a shared cover spray combustion airing system.
The present invention realizes by following scheme, parallel coal gasifier, include the body of heater that is provided with water jacket, vapour pipe, gas pipe, it is characterized in that forming coal gasification furnace by two bodies of heater, link to each other with a cover coal gas jet burning system, the vapour pipe of coal gasification furnace communicates with furnace water jacket, the spout of vapour pipe is positioned at the place suitable for reading that hot blast is responsible for, one end of gas pipe communicates with the upper top of body of heater, the lower end links to each other with the dedusting water tank, the dedusting water tank links to each other with injector, and gas pipe is set with hot blast outward and is responsible for, and blind flange is equipped with in the lower end that hot blast is responsible for, one end of hot blast bend pipe is responsible for hot blast and is communicated, the other end links to each other with the suction port of high pressure blower, and the delivery port of high pressure blower links to each other with the air intake bend pipe, and the air intake bend pipe communicates with the gasification hearth bottom.
The present invention is made up of two bodies of heater, links to each other with a cover coal gas jet burning system, adopts the alternately mode of coal, and mixture heat coal gas is output continuously just, makes full use of coal resources, replace oil with coal reduces and pollutes, and has reached uninterruptedly, the purpose of continuous aerogenesis.
Hot blast of the present invention is responsible for and is sleeved on outside the gas pipe, make the steam that produces in the body of heater directly spray on the gas pipe, the waste heat that makes full use of on the gas pipe makes water vapor keep higher temperature, after the air mixed that enters in the hot blast person in charge, send into fuel bed in the burner hearth by high pressure blower from furnace bottom, carry out gasification reaction, generate coal gas.
The delivery port of injector of the present invention is integrated, and in injector, the confluce of two coal gas output tubes is provided with dividing plate, when the gas ejector of this structure formation can solve existing separate unit body of heater coal gasification furnace operation, coal, coal gas is interrupted, and needs igniting again, with serious pollution drawback.When the coal producer of two bodies of heater compositions moves simultaneously, when wherein need are opened the coal filling hole coal, pressure in the burner hearth is on a declining curve, coal filling hole can overflow bituminous coal gas, at this moment, and another coal gasification furnace, by another gas pipe in the injector, form negative pressure in the burner hearth with the need coal, this negative pressure had both suppressed the bituminous coal gas that may overflow because the burner hearth internal drop is low, had guaranteed the stable output of qualified coal gas in another body of heater again.
The present invention has the following advantages and effect: 1, two in parallel uses of coal gasification furnace, adopt alternately coal-adding type, and can make the continuous output of mixture heat coal gas; 2, at the gas exit place of two coal gasification furnaces injector is installed, bituminous coal gas outwards overflows when having prevented coal, contaminate environment; 3, efficient energy-saving, operate steadily, two units move simultaneously, do not need to light a fire again, coal gas is uninterrupted; 4, safe and reliable, simple to operate, economical and practical; 5, vaporization rate height, hard coal ≈ 3.5Nm
3/ kg, bituminous coal ≈ 3.3～3.7Nm
3/ kg; 6, applied widely, use in the place that can be used for Heating temperature≤1200 ℃, as Industrial Stoves, and industries such as thermal treatment, boiler, chemical industry, building materials, hotblast stove, drying shed non-ferrous metal metallurgy, agricultural byproducts drying; 7, the mixed gas quality height of output, thermal value range is at 5000～5500KJ/Nm
3, all other technical indicators, quality product, environment monitoring all reach relevant national standard after tested.
