Abstract
The utility model belongs to a waste heat recovery production device used for a fixed-bed intermittent gas generation system and relates to a device for simply removing dust before the blowing air entering into a combustion furnace. The utility model solves the technical problem of recovery of dust generated by the fixed-bed intermittent gas producing device. The device for simply removing dust before the blowing air entering into the combustion furnace comprises a three-way pipe connected in front of the combustion furnace, wherein the inlet end of the three-way pipe is connected with the outlet of a dust collector, the combustion furnace is connected at the other end of the three-way pipe, and a water seal is connected at the lower end of the three-way pipe. The device has the advantages of simple operation, little increase of investment cost, greatly reduced dust entering the waste heat recovery system, no phenomenon of dust blockage and reduced damage of dust to the device.
Description
Technical field
The utility model belongs to batch (-type) fixed bed coal gas generating system waste heat recovery production equipment, is specially a kind of blowing-out gas and advances the preceding simple dust arrester of combustion furnace.
Background technology
The fixed bed intermittently device of coal gas producing will discharge a large amount of blowing-out gas in gas-making process, wherein blowing-out gas is carried a large amount of dust, if these dust enter residual neat recovering system, will cause the stifled generation of system's ash easily.Therefore, ash is stifled is that the chemical fertilizer factory of a great problem that present air blown gas recovery unit faces, especially combustion coal and little beans is particularly outstanding.General process units is that blowing-out gas is before entering combustion furnace at present, at first enter combustion furnace again through after the cyclone dust collectors dedusting of gasification system, but only can not reach desirable effect through one-time dedusting, if ature of coal is bad, the easier shutoff that causes residual neat recovering system.
Summary of the invention
The utility model is in order to solve the intermittently technical problem of the recovery of the dust that produces of the device of coal gas producing of fixed bed, and provides a kind of blowing-out gas to advance simple dust arrester before the combustion furnace.
The utility model is realized that by following technical scheme a kind of blowing-out gas is advanced the preceding simple dust arrester of combustion furnace, comprises being connected combustion furnace threeway before, and the entrance point of threeway connects the deduster outlet, other end connection combustion furnace, and the lower end connects water seal.
Blowing-out gas wherein still contains a large amount of dust, for further dedusting after the dedusting of process gasification system cyclone dust collectors.The utility model utilizes the inertial dust collection principle, before entering combustion furnace, sets up in pipeline a three-way device in conjunction with water seal, when the dust in the blowing-out gas enters, can drop to following water seal according to principle of inertia, and when ash discharge, can open the outlet valve below the water seal, make dust and water together along outflow in inclined-plane of water seal bottom surface.
Device described in the utility model is simple to operate, increases investment cost hardly, enters residual neat recovering system but can significantly reduce dust, has avoided causing the stifled phenomenon of ash to take place, and has reduced the damage that dust causes equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
As schematically shown in Figure 1, a kind of blowing-out gas is advanced the preceding simple dust arrester of combustion furnace, comprises being connected combustion furnace 1 threeway 2 before, and the entrance point of threeway 2 connects the deduster outlet, lower end connection water seal 3.Water seal 3 upper ends are water inlet, and bottom surface is the inclined-plane, and the next door is a flowing water Valve.
Claims (1)
