Description

A kind of calcium carbide stove exhaust retracting device
Technical field
This utility model is related to boiler exhaust gas process field, more particularly to a kind of calcium carbide stove exhaust retracting device.
Background technology
At present, the application of furnace of calcium carbide contains substantial amounts of waste heat, if do not carried out than wide in the tail gas that furnace of calcium carbide is produced Recycle and be directly discharged in air, serious residual heat resources on the one hand can be caused to waste so that the whole system thermal efficiency Low, energy-output ratio is big;On the other hand high-temp waste gas are directly discharged in air can be to environment.Therefore, to carbide The process problem of furnace exhaust gas waste heat is gradually attracted attention.Although occurring in that some exhaust emissions heat recoveries are filled at present Put, but heat recovery efficiency is low, complex structure, cost are higher, be not suitable for medium-sized and small enterprises.
Utility model content
The purpose of this utility model is and a kind of calcium carbide stove exhaust for proposing in order to solve shortcoming present in prior art Retracting device.
To achieve these goals, this utility model employs following technical scheme:
A kind of calcium carbide stove exhaust retracting device, including exhaust emission tube, heating water tank and spray column, the exhaust emission tube It is connected with furnace of calcium carbide, exhaust emission tube is connected internally to the bottom of spray column through heating water tank, the exhaust emission tube is located at Part in heating water tank is bending coil pipe, and the part that exhaust emission tube is located in heating water tank is also uniformly provided with some fins;
The spray column inner upper is provided with the shower through spray column, and the part that shower is located in spray column is provided with Some spray heads, the other end of shower are provided with booster pump, and booster pump is in spray water tank.
Preferably, one end that the exhaust emission tube is contacted with furnace of calcium carbide is additionally provided with filter layer.
Preferably, the heating water tank is also associated with water inlet and outlet.
Compared with prior art, the beneficial effects of the utility model are:
1st, the tail gas that furnace of calcium carbide production is produced enters spray column through exhaust emission tube, and high-temperature tail gas are in heating water tank Water is heated, and the water through heating can be used for heating or other purposes, has saved heat energy, has reduced energy loss.
2nd, exhaust emission tube is located at the part in heating water tank to bend coil pipe, increases the contact area with water, improves Heat exchanger effectiveness.The part that exhaust emission tube is located in heating water tank is also uniformly provided with some fins, and fin increases hot friendship Area is changed, heat exchanger effectiveness is improve.
3rd, spray column can be sprayed to tail gas, and tail gas is met water in spray column and forms water vapour, then from spray column The tail gas discharging pipe at top is drained in air, realizes environmentally friendly, safe and nontoxic discharge, meets the waste gas row that relevant laws specify Put standard.
Description of the drawings
Fig. 1 be the utility model proposes a kind of calcium carbide stove exhaust retracting device structural representation.
In figure:1st, furnace of calcium carbide, 2, exhaust emission tube, 3, fin, 4, filter layer, 5, spray column, 6, heating water tank, 7, water inlet Mouthful, 8, outlet, 9, shower, 10, spray head, 11, tail gas discharging pipe, 12, spray water tank, 13, booster pump.
Specific embodiment
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described Embodiment is only a part of embodiment of this utility model, rather than the embodiment of whole.
With reference to Fig. 1, a kind of calcium carbide stove exhaust retracting device, including exhaust emission tube 2, heating water tank 6 and spray column 5, institute State exhaust emission tube 2 to be connected with furnace of calcium carbide 1, exhaust emission tube 2 is connected internally to the bottom of spray column 5, institute through heating water tank 6 The tail gas for stating the production generation of furnace of calcium carbide 1 enters spray column 5 through exhaust emission tube 2, and high-temperature tail gas enter to the water in heating water tank 6 Row heating, the water through heating can be used for heating or other purposes, saved heat energy, reduced energy loss.Spray column 5 can To spray to tail gas, tail gas is met water in spray column 5 and forms water vapour, then the tail gas discharging pipe from the top of spray column 5 11 drain in air, realize environmentally friendly, safe and nontoxic discharge, meet the waste gas emission standard that relevant laws specify.
The exhaust emission tube 2 is located at the part in heating water tank 6 to bend coil pipe, increases the contact area with water, Improve heat exchanger effectiveness.The part that the exhaust emission tube 2 is located in heating water tank 6 is also uniformly provided with some fins 3, fin 3 increase heat exchange area, improve heat exchanger effectiveness.
5 inner upper of the spray column is provided with the shower 9 through spray column 5, and shower 9 is located at the portion in spray column 5 Some spray heads 10 are arranged with, the other end of shower 9 is provided with booster pump 13, and booster pump 13 is in spray water tank 12.Tail gas Into after spray column 5, booster pump 13 extracts the water in spray water tank 12 and sprays from spray head 10, and tail gas is met in spray column 5 Water forms water vapour, and then the tail gas discharging pipe 11 from the top of spray column 5 is drained in air.
