Description
Technical Field
The invention belongs to the technical field of environmental protection equipment, and relates to a gas collection device, in particular to a modularized combined type regeneration furnace pyrolysis gas collection device for regenerating powdered activated carbon.
Background
The activated carbon is used as an adsorbent with wide application, the annual usage amount of various industries is considerable, and the regenerated saturated activated carbon has strong economic and environmental benefits and is supported and encouraged by national policies. The heat regeneration method is the most widely used and industrially most mature activated carbon regeneration method.
At present, the activated carbon needs to be heated, and pollutants adsorbed by the activated carbon are decomposed into pyrolysis gas and discharged in the heating process, so that the regeneration process is completed.
Because the gas is generated in the furnace in the regeneration process, the furnace is in a positive pressure state, but for safety, the gas in the furnace is smoothly discharged, a negative pressure state is required to be arranged at a pyrolysis gas discharge port, the negative pressure cannot be too large, otherwise, the negative pressure in the furnace can be caused, a series of adverse effects such as carbon powder combustion loss and abnormal uncontrollable high temperature in the furnace can be caused, the regeneration efficiency is low, the service life of equipment is reduced, and serious safety accidents can be even caused. On the other hand, the discharged pyrolysis gas has a high temperature of about 800 degrees and is also a flammable and explosive gas, and it is necessary to perform a cooling dilution treatment.
Disclosure of Invention
In order to solve the technical problems, the invention provides a device for collecting pyrolysis gas, which is used for accurately adjusting the negative pressure of a pyrolysis gas discharge pipe outside a furnace, rapidly cooling the discharged pyrolysis gas and diluting inflammable and explosive gas.
The technical scheme adopted by the invention is as follows: the utility model provides a regenerator pyrolysis gas collection device which characterized in that: comprises an internal negative pressure purifying tower, an air suction pipe of the purifying tower, a flaring type movable sleeve and a cracking gas discharge pipe of a regenerating furnace;
the flaring type movable sleeve can axially move along the pipe; the internal negative pressure purifying tower is connected with the regenerating furnace sequentially through an air suction pipe of the purifying tower, a flaring moving sleeve and a cracking gas discharge pipe of the regenerating furnace.
According to the invention, by utilizing the adjusting function of the flaring type movable sleeve, external ambient air and high-temperature pyrolysis gas in the furnace are mixed and sucked into the purifying tower under the negative pressure function, so that the accurate adjustment of the air pressure in the furnace can be realized, the rapid cooling of the high-temperature pyrolysis gas can be realized, and meanwhile, the accidental detonation risk of the pyrolysis gas is relieved due to the effect of the external air proportion mixing. The invention has simple structure, convenient manufacture and installation and obvious effect.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention;
fig. 2 is a schematic view of a connecting pipeline according to an embodiment of the present invention.
Detailed Description
The present technical solution is further described below with reference to the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout, but the description is merely for explaining the present invention and is not to be construed as limiting the present invention.
Referring to fig. 1, the invention provides a pyrolysis gas collecting device of a regenerator. Comprises an internal negative pressure purifying tower 1, a purifying tower air suction pipe 2, a flaring type movable sleeve 3 and a regenerating furnace pyrolysis gas discharge pipe 4; the internal negative pressure purifying tower 1 is connected with the regenerating furnace through a purifying tower air suction pipe 2, a flaring type movable sleeve 3 and a regenerating furnace pyrolysis gas discharge pipe 4 in sequence.
The activated carbon is heated in the regenerating furnace to generate pyrolysis gas, and the pyrolysis gas is conveyed to the internal negative pressure purifying tower 1 under the action of the negative pressure of the internal negative pressure purifying tower 1 by a connecting pipeline consisting of the purifying tower air suction pipe 2, the flaring movable sleeve 3 and the regenerating furnace pyrolysis gas discharge pipe 4. The negative pressure in the internal negative pressure purifying tower 1 is generated by a connected fan. The air quantity can be regulated by regulating the rotation speed of the variable frequency motor and the air pressure can be regulated by changing the opening of the valve of the inlet and the outlet, but the pressure conditions in the regenerating furnace are rough regulation, the aim of accurate regulation is hardly achieved, the means can only change the total negative pressure value in the internal negative pressure purifying tower 1, and the specific regulation can not be carried out for each pyrolysis gas connecting pipeline.
Referring to fig. 2, the pyrolysis gas connecting pipeline detailed structure comprises a purifying tower air suction pipe 2, a flaring moving sleeve 3 and a regenerator pyrolysis gas discharge pipe 4.
Because the flaring type movable sleeve 3 is movable and is in flaring connection with the pyrolysis gas discharge pipe 4 of the regenerating furnace, when the sleeve is moved, the gap between the flaring type movable sleeve 3 and the pyrolysis gas discharge pipe 4 of the regenerating furnace can be changed, the gap is similar to the valve opening degree adjustment, the size of the gap is adjusted by moving the flaring type movable sleeve 3, and the negative pressure value can be independently adjusted for each pyrolysis gas connecting pipeline, so that the aim of stabilizing the micro-positive pressure state in the regenerating furnace and not generating any negative effect on the conditions in the furnace is fulfilled. Meanwhile, as the gap is always reserved between the sleeve flaring of the flaring type movable sleeve 3 and the pyrolysis gas discharge pipe 4 of the regenerating furnace, and the sizes of the gaps are different, external ambient gas is sucked into the connecting pipeline to be mixed with the pyrolysis gas under the action of negative pressure of the purifying tower, so that the temperature of the pyrolysis gas can be rapidly reduced, and meanwhile, the pyrolysis gas is diluted and is far away from the gas burning and explosion critical range. The external ambient gas may be a protective gas or air as needed. Even the controlled combustion reaction can be deliberately made at the sleeve flaring, facilitating the treatment of post-pyrolysis gases.
It should be understood that parts of the specification not specifically set forth herein are all prior art.
It should be understood that the foregoing description of the preferred embodiments is not intended to limit the scope of the invention, but rather to limit the scope of the claims, and that those skilled in the art can make substitutions or modifications without departing from the scope of the invention as set forth in the appended claims.
