Description

High temperature fume purification device

Technical field

The utility model relates to fume pollution and purifies and the recovery field, specifically relates to the high temperature fume purification device that produces in a kind of parched rice process.

Background technology

Aromatic vinegar is the distinguishing products in a place, and parched rice is painted to vinegar is one important process that aromatic vinegar is produced.Parched rice is that rice is put into to frying pan, open firing, and the rice in pot is constantly overturn by mixer, and after Mi Shoure, constantly dehydration, decarburization, helvolus by leucismus, more yellow black by xanthochromia, until the material coking such as the starch in rice and not being carbonized forms melanin.

In the parched rice process, due to the effect of heating furnace burner hearth high-temperature heating, the starch pyrolysis of partly being heated in rice, separate out the oil smoke that contains tar and steam, and the temperature of oil smoke is 400 ℃ of left and right.The high-temperature oil smoke that produces, it is a kind of class sapropelitic, has high viscosity, the object that is difficult to clear up, this oil smoke very easily is adsorbed on the solid of all contacts, again because it has combustibility, so contaminated environment not only, bring very large impact for surrounding resident and sauce vinegar factory, also have very large potential safety hazard.In addition, tar has again dividing of large molecule tar and little molecule tar, particularly little molecule tar, and diffusivity is strong, and pollution range is wider.

At present, more for the purification method of oil smoke, mainly for the oil smoke of catering trade generation.Because parched rice oil smoke temperature is high, tar content is high, viscosity is strong, traditional purification method undesirable, greatest problem is that smoke pumping problem, cleaning equipment purification efficiency are not high and low to the high temperature recovery utilization rate of its generation, and serious water pollution problems occurs.

Summary of the invention

For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of harm that can eliminate tar, and the purification recovery device of the parched rice oil smoke that its energy is reclaimed.

The technical solution adopted in the utility model is as follows:

High temperature fume purification device, this device is vertical at the top of smoke exhaust pipe 3, in described high temperature fume purification device, is disposed with high temperature smoking 4, electrothermal furnace 10, heat exchanger 9 and air-introduced machine 8 from bottom to top.

Electrothermal furnace 10 is the constant temperature resistance furnaces of being arranged and being formed by the multilayer resistance wire, and described electrothermal furnace 10 is positioned at the top of high temperature fume extracting device 4.

Described electrothermal furnace 10 connects the AC power of constant voltage, makes resistance wire remain the high temperature that makes grill burner always.Described heat exchanger 9 is positioned at the electrothermal furnace top, in it, is provided with the cooling water circulation pipeline.Described cooling water circulation pipeline heat exchanger feed pipe 5 is arranged on the bottom that heat exchanger is discharged water pipe 6, and water flows from bottom to top in circulating line, by from bottom to top hot gas, is heated, and the water of heating can be used as the recyclings such as boiler feedwater.

Parched rice pot 2 tops are equipped with automatic rotating body 11, under the regulation rotating speed, rotate and drive the agitator rotation, thereby the rice in the parched rice pot can be heated evenly, and are time saving and energy saving.

The utility model utilizes parched rice process self-condition and combines with boiler, has formed the clean-production system of a closed cycle, has solved the fume pollution in the production process and has purified the recovery problem, with other lampblack purifying system, compare, system is simple, and reliability is high, has avoided secondary pollution.

The specific embodiment

For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, utility model is further described.

As Fig. 1, the purifier of parched rice oil smoke of the present utility model, comprise that this device is vertical at the top of smoke exhaust pipe 3, in described high temperature fume purification device, is disposed with electrothermal furnace 10, heat exchanger 9 and air-introduced machine 8 from bottom to top.

Its technical process is as follows: fuel mixed combustion in heating furnace burner hearth 1, emit heat, and give the parched rice pot 2 heating, also remain burner hearth high temperature simultaneously; Rice in parched rice pot 2 is stirred device 13 and does not stop to stir when being heated, be heated evenly, when rice is heated to uniform temperature, in rice, moisture starts to separate out, become steam, temperature continue to raise, the pyrolysis of partly being heated of the starch in rice, separate out molecular weight different gaseous state tar and steam, form high-temperature oil smoke; Utilize pot cover 12 to stop oil smoke to enter in air, force oil smoke 4 to enter smoke exhaust pipe 3, by air-introduced machine 8, oil smoke 4 is sucked in electrothermal furnaces 10 and decomposes, burn, oil smoke is thoroughly purified, and the flue gas that in heating furnace, burning generates is emptying after by heat exchanger 9 recovery heats.

As shown in Figure 2, electrothermal furnace device 10 is comprised of resistance wire 14, power supply 15.Air-introduced machine 8 entrainments high-temperature oil smoke and travels forward, and constant temperature electric heating stove 10 is by its burning, and this apparatus structure is simple, easy to operate, purification is thorough, environment friendly and pollution-free, can adapt to various environment, does not have moving component, and is easy to maintenance.

Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various modifications to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
