Technical Field

The utility model relates to a boiler smoke desulphurization unit convenient to control.

Background

A large amount of gases such as sulfur dioxide, carbon monoxide and carbon dioxide are generated in the coal burning process, wherein the sulfur dioxide can cause acid rain, the carbon monoxide is a toxic gas and can harm human health, the carbon dioxide is the main cause of greenhouse effect, and in order to protect the environment, the gases generated in the coal burning process need to be treated and filtered to prevent the gases from influencing the environment.

The Chinese utility model patent with publication number CN 207533048U, granted and announced by 26.06.8.2018, discloses a smoke discharging and desulfurizing device, which comprises a bracket and a tank body fixed on the bracket, wherein the upper end of the side wall of the tank body is provided with a smoke discharging pipe and a water inlet pipe which are communicated with the inside of the tank body, the smoke discharging pipe is provided with a fan, and the water inlet pipe is provided with a first valve; the lower end of the side wall of the tank body is provided with a smoke inlet pipe and a water outlet pipe which are communicated with the interior of the tank body, and the water outlet pipe is provided with a second valve; lime water is filled in the tank body; the upper portion and the lower portion of the side wall of the tank body are respectively provided with a first transparent visual window and a second transparent visual window, and the first visual window is provided with scales.

The device mainly depends on the reaction of the lime water and the sulfur dioxide in the flue gas, and the following reactions occur:

①.SO₂+Ca(OH)₂＝CaSO₃↓+H₂o, calcium sulfite precipitates, the lime water becomes turbid, and the temperature is changed to ② & 2SO with the continuous entering of sulfur dioxide gas₂+Ca(OH)₂＝Ca(HSO₃)₂The main reason is that calcium hydrogen sulfite is generated, the calcium hydrogen sulfite is soluble in water, the lime water has a reduced tendency of becoming turbid or even a tendency of becoming clear, the calcium hydrogen sulfite is only present in the water and is unstable, therefore, the inside of the desulfurization device is mainly ①, which requires that Ca (OH) in the lime water is used₂The excess is maintained and the alkalinity is maintained. Although the existing flue gas desulfurization device is provided with the first visual window and the second visual window, the pH value of the lime water in the tank body is not convenient to judge. In addition, the calcium sulfite sediment generated by the smoke discharging and desulfurizing device is easy to be silted up at the water outlet pipe 7 to block the valve on the water outlet pipe.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is how to overcome the above-mentioned defect of prior art, provide a boiler smoke desulphurization unit of being convenient for control of easy mediation when being convenient for monitor, adjust the basicity of lime wash, export jam.

In order to solve the technical problem, the boiler smoke desulfurization device convenient to control comprises a tank body and a top cover, wherein a circular flanging is arranged at the upper opening of the tank body, the top cover is detachably fixed on the flanging of the tank body through a plurality of bolts, an air inlet pipe and an exhaust pipe are further arranged on the top cover, a drain pipe is arranged at the bottom of the tank body, lime water is stored in the tank body, the tail end of the air inlet pipe is introduced below the liquid level of the lime water, and the exhaust pipe is communicated with the internal space of the tank body above the liquid level.

The method is characterized in that: the tank body is made of transparent materials, the top of the tank body is also provided with a lime water feeding pipe and an acid/alkali indicator feeding pipe, the lime water feeding pipe and the acid/alkali indicator feeding pipe are respectively provided with a feeding valve, the sewage discharge pipe is sleeved with a sewage discharge hose, the other end of the sewage discharge hose is sleeved on a section of sewage discharge steel pipe, the top cover is directly or indirectly welded with an upper clamping column and a lower clamping column, the sewage discharge hose is hung on the upper clamping column after bypassing the lower clamping column after being flattened, and the sewage discharge hose can be sealed under the gravity action of the sewage discharge steel pipe and part of the sewage discharge hose,

it has the screw thread blind hole to open in the top cap center, and this screw thread blind hole center is opened has vertical through-hole, wears to be equipped with one on the vertical through-hole and prevents stifled pole, should prevent stifled pole lower extreme and be equipped with a pressure disk, and this pressure disk outer fringe external diameter is less than the internal diameter of sewer, should prevent stifled pole top and be equipped with the handle, and this handle hangs in the top cap top through a couple, prevents still having annular gland and sealing ring on the stifled pole, be equipped with the external screw thread on the annular gland to install through the external screw thread in the screw thread blind hole, the sealing ring is extruded annular gland, top cap and prevents stifled between the pole, forms the shaft seal, the handle of preventing stifled pole breaks away from behind the couple. The sewage discharge hose is preferably a high-pressure nylon hose for fire fighting.

Before the device is used, a feed valve on a lime water feed pipe is opened, lime water is injected into a tank body and enabled to submerge the lower end of an air inlet, then the feed valve on the lime water feed pipe is closed, the feed valve on an acid/alkali indicator feed pipe is opened, a proper amount of purple litmus indicator or colorless phenolphthalein indicator is injected into the lime water (the dosage of the purple litmus indicator is based on that the lime water injected with the purple litmus indicator presents obvious blue, and the dosage of the colorless phenolphthalein indicator is based on that the lime water injected with the colorless phenolphthalein indicator presents obvious red), then an air inlet pipe is communicated with a matched flue, and the sulfur removal of boiler smoke can be started. In the process, sulfur dioxide in the smoke enters lime water to generate calcium sulfite sediment, a large amount of calcium sulfite sediment is observed to be accumulated at the lower part of the tank body, the sewage discharge steel pipe and the sewage discharge hose are taken down from between the upper clamping column and the lower clamping column and are stretched, and the calcium sulfite sediment in the tank body is discharged (possibly carrying a small amount of lime water).

When calcium sulfite or calcium carbonate caking appears in the sewage discharge hose, the caking can be crushed and discharged only by properly extruding and bending the sewage discharge hose. When the sewage outlet is blocked or caked, the anti-blocking rod only needs to be taken down from the hook and then downwards extended into the sewage discharge pipe to poke for a few times, so that the device is very convenient.

During the use process, when the purple litmus indicator begins to turn purple or the colorless phenolphthalein indicator begins to turn colorless, Ca (OH) in the lime water in the tank body is indicated₂When the water is exhausted, the sewage steel pipe and the sewage hose are taken down from between the upper clamping column and the lower clamping column and are stretched, the lime water in the 2/3 tank body is discharged, and then the sewage steel pipe and the sewage hose are clamped on the upper clamping column and the lower clamping column again. Then opening a feed valve of a feed pipe of the lime water feed pipe, supplementing fresh lime water, adding a proper amount of purple litmus indicator or colorless phenolphthalein indicator, and finally enabling the lime water in the tank body to reach half of the volume of the tank body or 2/3.

So design, the basicity of lime wash in can the real-time observation jar body prevents that lime wash from presenting unable effective absorption sulfur dioxide behind neutral or the acidity, and does not have the valve on blowdown hose and the blowdown steel pipe, and jar internal anti-blocking pole that is equipped with when appearing blow off pipe or blowdown hose jam, dredges very easily.

Preferably, an axial flow fan is arranged on the air inlet pipe or the air outlet pipe. By the design, the smoke flows smoothly.
