Abstract
The utility model provides a countercurrent exchange-type dry desulfurization device which comprises an upper housing, an intermediate housing, a lower housing and a support. The countercurrent exchange-type dry desulfurization device is characterized in that a gas outlet is arranged on one side of the upper housing, a feed port is arranged on the upper housing, a gravity valve is arranged below the feed port, a wind-distributing cone and a flue gas passage are arranged inside the intermediate housing, a heat-insulating layer is arranged outside the intermediate housing, a gas inlet is arranged on one side of the lower housing, a discharge port is arranged on the other side of the lower housing, and the support is arranged at the bottom of the lower housing. The countercurrent exchange-type dry desulfurization device achieves the purpose of high-efficiency desulfurization with low investment, low energy consumption and environmental friendliness.
Description
Technical field
The utility model relates generally to the kiln gas desulfurization of brick and tile enterprise, also can be used for the gas cleaning of enterprises such as ceramic enterprise, refractory material, glass.
Background technology
Flue gas sulphur removal equipment of the prior art, major part is the wet type sulphur removal.In desulfurizing tower, remove SO in the flue gas with akaline liquid
2And SO
3This method cost height, floor space is big, and pipeline and equipment corrosion are serious, thereby the maintenance cost height.Complicated operation is wanted constantly the liquid after the desulfurization to be chemically examined in addition, regulate acid-base value, so operating cost is big.The bad processing of waste liquid after the desulfurization.Enterprise is after using this desulphurization plant, and production cost strengthens a lot.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of counterflow exchange formula dry desulfurization device is provided, and can reach desulfurization purpose, small investment and energy-conserving and environment-protective effectively.
The technical scheme that realizes the utility model purpose is, a kind of counterflow exchange formula dry desulfurization device comprises upper shell, middle shell, lower house and support, it is characterized in that being provided with the gas outlet in upper shell one side, on upper shell, be provided with charging aperture, weight valve arranged below the charging aperture; In middle shell, be provided with cloth wind awl and exhaust gases passes, be provided with heat-insulation layer in the middle shell outside; Be provided with air inlet in lower house one side, opposite side is provided with discharging opening, is provided with support in the bottom of lower house.
This device has been compared following advantage with the conventional wet desulfurizer: a) small investment.B) do not have etching problem, maintenance capacity is little.C) do not need special Ca (OH)
2Device and expense, thereby operating cost is low.D) do not need special chemical examination program, simple to operate.E) do not have reaction back waste residue water intractable problem, dried waste residue can directly mix in the brick-making raw material.F) institute's heat content can make full use of good energy-conserving effect in the flue gas.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, whole device is installed on the support 10, comprises upper shell 3, middle shell 5 and lower house 8, and limestone particle and appropriate amount of catalysts enter in the middle shell 5 by upper shell 3 from charging aperture 1, be deposited in above the cloth wind awl 7, heat-insulation layer 6 plays the effect of insulation; The flue gas that has sulfur dioxide enters in the middle shell 5 by lower house 8 from air inlet 11, and under certain conditions, dried particle of lime stone and sulfur dioxide in flue gas generation displacement reaction generate calcium sulfate and carbon dioxide, thereby reaches the purpose of desulfurization.
Its chemical equation is:
CaCO
3 (Gu)+ SO
2 (gas)→ CaSO
3 (Gu)+ CO
2 (gas)↑
2CaSO
3 (Gu)+ O
2 (gas)→ 2CaSO
4 (Gu))
The CaSO that produces
4The solid gypsum is discharged from discharging opening 9 because the gravity effect drops in the lower house 8, can be used in the raw material of brick and tile as preparing burden the nothing discharging.CO
2Gas enters in the upper shell 3 through exhaust gases passes 12 and since weight valve 2 stop CO
2Gas can only be from the gas outlet 4 be discharged, and the hot flue gas after the desulfurization is incorporated into hothouse with air-introduced machine and is used again, reaches energy-conservation purpose.This device is 10,000 m applicable to exhaust smoke level
3/ h～150,000 m
3The Industrial Stoves of/h.Desulfuration efficiency: SO in flue gas
2Content is 1200mg/m
3～1800mg/m
3, can reduce to 150～200mg/m by this desulfurizer
