Abstract
The utility model discloses a shaft furnace coal gas heat exchanger waste fitting discharging, including giving vent to anger box, outlet duct, intake pipe, the box that admits air, funnel and coal gas economizer bank, give vent to anger the box setting at the top of admitting air the box, the tank wall of the give vent to anger box and the box that admits air be hollow seal structure, and the inside of the give vent to anger box and the box that admits air all sets up a plurality of coal gas economizer banks, and one side tank wall intercommunication of the give vent to anger box and the box that admits air sets up outlet duct and intake pipe respectively on the other side of the box and the box that admits air of giving vent to anger, it connects the funnel to admit air the bottom of box, and the funnel comprises a plurality of seamless pipes, wherein the one end intercommunication of the seamless pipe space in the box tank wall of admitting air. The funnel is connected in the bottom of the box that admits air to this practicality for moisture and impurity in the gas subside the inside that falls into the funnel, emit into the gas flashback tank at last in, avoided moisture and impurity to plug up the port of coal gas economizer bank, improve the life and the availability factor of heat exchanger.
Description
Technical field
The utility model relates to a kind of blowdown apparatus, specifically a kind of shaft furnace coal gas heat exchanger blowdown apparatus.
Background technology
Shaft furnace coal gas heat exchanger is made up of upper and lower two casings, have 137 φ 60*2000mm(long in a casing) gas pipe, moisture content, impurity is there is in coal gas due to use, coal gas produces resistance when being horizontally through upper box by lower box, the moisture existed in coal gas and impurity to be easily obstructed gathering in tank ends, cause moisture, impurity more, blocking coal gas heat-exchange tube, in addition, in coal gas, impurity contains corrosive elements, time one length causes gas pipe corrosion air-leakage, causes heat exchanger to scrap.
Utility model content
The purpose of this utility model is to provide a kind of shaft furnace coal gas heat exchanger blowdown apparatus, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of shaft furnace coal gas heat exchanger blowdown apparatus, comprise casing of giving vent to anger, escape pipe, air inlet pipe, air inlet casing, funnel and gas preheating pipe, described casing of giving vent to anger is arranged on the top of air inlet casing, the tank wall of casing and air inlet casing of giving vent to anger is hollow seal structure, the give vent to anger inside of casing and air inlet casing all arranges some gas preheating pipes, casing of giving vent to anger is communicated with a side box wall of air inlet casing, sets out tracheae and air inlet pipe respectively giving vent to anger on casing and the other side of air inlet casing; The bottom of described air inlet casing connects funnel, and funnel is made up of multiple seamless pipe, and wherein one end of seamless pipe is communicated with the space in air inlet casing tank wall.
As further program of the utility model: the diameter of escape pipe is less than the diameter of air inlet pipe.
As further program of the utility model: the other end of seamless pipe connects gas-water joint sealing.
Compared with prior art, the beneficial effects of the utility model are: this practicality connects funnel in the bottom of air inlet casing, the moisture in combustion gas and impurity sedimentation is made to drop into the inside of funnel, finally be drained in gas-water joint sealing, avoid moisture and the port of gas preheating pipe is blocked by impurity, improve service life and the service efficiency of heat exchanger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of shaft furnace coal gas heat exchanger blowdown apparatus, comprise casing 1 of giving vent to anger, escape pipe 2, air inlet pipe 3, air inlet casing 4, funnel 5, gas-water joint sealing 6 and gas preheating pipe 7, described casing 1 of giving vent to anger is arranged on the top of air inlet casing 4, the tank wall of casing 1 and air inlet casing 4 of giving vent to anger is hollow seal structure, the give vent to anger inside of casing 1 and air inlet casing 4 all arranges some gas preheating pipes 7, casing 1 of giving vent to anger is communicated with a side box wall of air inlet casing 4, make the coal gas in air inlet casing 4 can enter into casing 1 of giving vent to anger, finally discharge use, set out tracheae 2 and air inlet pipe 3 respectively giving vent to anger on casing 1 and the other side of air inlet casing 4, the diameter of escape pipe 2 is less than the diameter of air inlet pipe 3,
The bottom of described air inlet casing 4 connects funnel 5, funnel 5 is made up of multiple seamless pipe, wherein one end of seamless pipe is communicated with the space in air inlet casing 4 tank wall, and the other end of seamless pipe connects gas-water joint sealing 6, thus when making the combustion gas of preheating in the tank wall entering into air inlet casing 4, moisture in combustion gas and impurity sedimentation drop into the inside of funnel 5, thus avoid moisture and impurity to be blocked by the port of gas preheating pipe 7.
Operation principle of the present utility model is: this practicality in use, kiln tail gas containing heat enters from the bottom surface of air inlet casing 4, then discharge from the end face of casing 1 of giving vent to anger, make the heat in kiln tail gas and the cooled coal gas generation heat exchange in gas preheating pipe 7, finally discharge cold kiln tail gas, play the effect of energy circulation, this practicality connects funnel 5 in the bottom of air inlet casing 4, the moisture in combustion gas and impurity sedimentation is made to drop into the inside of funnel 5, finally be drained in gas-water joint sealing 6, avoid moisture and the port of gas preheating pipe 7 is blocked by impurity.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
