Abstract

The utility model provides an oil smoke removing chimney, belonging to an environment-protecting product. The oil smoke removing chimney is a heat exchanger which has the filter function and can be arranged on a flue for discharging oil smoke. High temperature oil smoke passes through the oil smoke removing chimney and the oil vapor is condensed and is adsorbed on a high density type dust gauze as well as flows down to be collected, and the heated water can be reused. The oil smoke removing chimney is suitable for various dining halls and restaurants, can be connected in series to use, avoids the long flue, and prevents the chimney from self-igniting and the oil smoke from disturbing residents.

Description

A kind of oil smoke chimney that removes

One, technical field

The utility model belongs to environment-friendly products, relates to heat exchanger and stack gases and removes equipment, and particularly oil smoke gas is removed structure.

Two, background technology

The oil smoke gas removing discharging in size meal restaurant is now only arranged oil fume pump exhaust in the air by long flue with smoke exhaust ventilator, serious environment pollution, and the spontaneous combustion of also normal generation flue, and heat exchanger now only is used for the cooling condensation of chemical process High Temperature Gas, liquid.

Three, summary of the invention

The utility model is that heat exchanger and filter are filtered and remove wherein vaporization at high temperature oil in conjunction with the condensation that is used for oil smoke gas, and protects environment.

1, technical scheme:

Oil smoke gas is a kind of high-temperature gas that contains a large amount of volatile oil, makes wherein with the method for condensation that volatile oil is condensed into liquid, with the method for filtering its filtration is compiled again.Heat exchanger and filter are combined, can remove the oil in the oil smoke gas.

The utility model is to carry out at 5 to improve and innovation on the heat exchanger basis:

(1) adopt highly dense heat exchanger tube row to make heat-exchange tube, to reach volatile oil in the efficient rapid condensation oil smoke gas.

(2) upward establish close mesoporous metal filter screen between pipe row, in the hope of the little oil droplet of filter freezing.

(3) establish the slightly diaphragm plate of declivity between heat-exchange tube, both can compel the oil smoke cyclostrophic and bend sharp again dirty compiling of profit.

(4) the heat exchanger outer cylinder body is made squarely, in order to attached subsides exterior wall.

(5) cylindrical shell bottom perforate and establish the belt switch pipe is to be used for the profit that the regular discharge tube compiles.

2, beneficial effect:

Remove oil gas in the oil smoke road, the protection surrounding environment is eliminated disaster hidden-trouble, efficiently utilizes fume afterheat.

Five, embodiment and example: (length millimeter)

1,361 of aluminium alloy light wall pipes adopting external diameter φ 12, length 1000 are made heat exchanger tube 10, adopt 4 on 588 * 400 * 0.1 iron plate, on all beat 19 * 13 in φ 12 holes and make diaphragm plate 8, adopt 2 on 588 * 588 * 0.3 iron plate, going up with 24 serves as to make upper and lower hydroecium plate 13,14 apart from all punching 19 * 19, by shown in Figure 2 pipe is worn each plate, regulating clapboard spacing is 200, with the slightly inside declivity of diaphragm plate 8,, between pipe row, all adorn 20-30 order metallic sieve and overlay heat exchanger tube 10 and make filter screen 9 after the tube sheet welding.

2, adopt interior empty 600 * 600 * 1100 * 0.6 one of iron square tube and make cylindrical shell 1, one in centre drill 150 holes of leading flank apart from following 150, weldering 150, long 300 thin gauge conduits are made air inlet pipe 2, apart from following 25, right edge 25 is bored one in φ 15 holes, weldering φ 15, long one in 300 water pipes are made water inlet pipe 3, apart from bottom 55, limit, left side 25, bore one in φ 8 holes, one of weldering φ 8, long 300 pipe are made oil-discharge pipe 6, are used for the regular discharge profit thereon with the Hose Jacket of belt switch.Cylindrical shell 1 top symmetric inlet pipe 3 left lateral positions boring weldering one same big outlet pipe 5.At cylindrical shell 1 upper rear portion symmetry air inlet pipe 2 boring welderings one same big blast pipe 4.Adopt 4 on 50 * 50 * 0.6 iron plate, centre drill φ 10 holes, be welded in cylindrical shell 1 leading flank and make preformed hole 7 for four jiaos.

3, will go up heat exchanger tube integral body that 1 step the was shaped cylindrical shell 1 of packing into, bottom respectively 50 welds in cylindrical shell 1 on the distance, after detecting upper and lower hydroecium plate 13,14 and each side pipe ne-leakage water phenomenon, adopt 2 on 588 * 588 * 0.6 iron plate, soldering and sealing cylindrical shell 1 upper and lower opening detects the weld seam ne-leakage and gets final product as upper and lower cover plate 11,12.This can be used for middle or small meal restaurant, and large-scale person can use its 2-4 series connection.

Claims

1, a kind of oil smoke chimney that removes with heat exchanger and filter combination, is characterized in that heat exchanger tube density height, and close mesoporous metal filter screen is arranged between pipe, and outer cylinder body is square, and the bottom perforate is also established the belt switch pipe.
