Description

Energy-saving and environment-friendly workshop air interchanger

Technical Field

The utility model relates to a workshop breather specifically is an energy-concerving and environment-protective workshop breather.

Background

Stack emissions from dedusting systems typically require that the height of the plant be exceeded and the gas be exhausted outdoors. At present, most manufacturers design that after a chimney is directly led out from the top of a factory building, gas is directly discharged from the chimney. Because the flow rate of the discharged gas is very high, kinetic energy is wasted because the gas is directly discharged outdoors. Simultaneously the factory building still takes a breath, needs such as cooling still need additionally set up facilities such as more roofing air discharge fan, causes whole high system architecture complicacy of arranging the cost, still need consider the wind current influence, and slight error will lead to the efficiency of taking a breath of discharging fume of factory building to reduce, influences factory building air quality.

In order to solve the problems, although the dust-free workshop ventilation and dust removal structure disclosed in chinese patent No. CN109469954A can effectively remove dust in a workshop, the structure of the dust-free workshop ventilation and dust removal structure is more complex and contains a large number of parts, so that the equipment installation process is more and great in early investment, and the dust removal structure is not beneficial for enterprises to reduce cost and improve efficiency.

Disclosure of Invention

Problem to above-mentioned prior art exists, the utility model provides an energy-concerving and environment-protective workshop breather can compromise the needs that the factory building was taken a breath and is cooled down with minimum cost effectively to the inside dust removal of factory building, can reduce the construction cost and the installation degree of difficulty of dust removal factory building effectively, effectively guarantee the dust removal of factory building, take a breath and the cooling demand.

In order to realize the purpose, the utility model discloses a following technical scheme realizes: the utility model provides an energy-concerving and environment-protective workshop breather, includes rain-proof cap, chimney, inlet port, accelerating taper pipe, dust remover and draught fan, embeds dust remover and draught fan in the factory building, and the dust remover passes through the tube coupling draught fan, and the air in the factory building is removed dust by the dust remover, and the draught fan provides power for the dust remover, makes the air can get into by the dust remover. The air exit erection joint of draught fan is to the outdoor chimney of factory building, and the chimney surface circumference that is located the factory building inboard and is close to the factory building top sets up the inlet port more than two, is close to the inboard welding installation of chimney of inlet port below and accelerates the taper pipe, and the little one end of taper pipe trompil is up with higher speed, and the rain-proof cap of support mounting is passed through on the chimney top, and the draught fan produces negative pressure suction, forms clean gas with the dirty gaseous filtration through the dust remover of dirt that needs to handle in the process of the preceding, upwards discharges the factory building top through the chimney. An accelerating taper pipe is arranged at the chimney section close to the top of the factory building, and air inlet holes are uniformly distributed on the periphery of the chimney. According to the Venturi jet principle, after clean gas with high flow velocity in the chimney passes through the accelerating taper pipe, the wind speed is further enhanced, so that a low-pressure area is formed around the air inlet hole, dirty air and heat at the top of a workshop are sucked into the chimney and discharged outdoors, the air in the workshop is purified, and the energy consumption is also saved. The air inlet can be opened and closed as required, and can be closed when heat preservation and other requirements are required in a workshop. A rain-proof cap guarantees that rainwater weather chimney does not intake water and damages equipment.

As a further improvement of the utility model, the air inlet is equipped with the valve in the inboard.

As a further improvement of the utility model, the air valve equipped in the air inlet adopts electromagnetic control.

As a further improvement of the utility model, the air inlet hole adopt a trapezoidal air inlet hole.

As a further improvement of the utility model, the upper end of the acceleration taper pipe is higher than the air inlet.

Borrow by above-mentioned scheme, the utility model discloses at least, have following advantage: compare with conventional dust removal factory building, this scheme utilizes venturi efflux principle, the higher discharge gas of velocity of flow further accelerates through the taper pipe in the chimney, make and form negative pressure zone around the taper pipe, it is outdoor to inhale the discharge in the chimney with the foul air and the heat at workshop top, workshop air has been purified, energy resource consumption has also been saved, can effectively compromise the needs of factory building cooling of taking a breath when removing dust to factory building inside with minimum cost, can reduce the construction cost and the installation degree of difficulty of dust removal factory building effectively, effectively guarantee the dust removal of factory building, take a breath and cooling demand.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in the figures 1 and 2, the energy-saving and environment-friendly workshop ventilation device comprises a rain-proof cap 1, a chimney 2, an air inlet 3, an accelerating taper pipe 4, a dust remover 5 and an induced draft fan 6, wherein the dust remover 5 and the induced draft fan 6 are arranged in a workshop, the dust remover 5 is connected with the induced draft fan 6 through a pipeline, air in the workshop is removed by the dust remover 5, and the induced draft fan 6 provides power for the dust remover 5, so that the air can enter from the dust remover 5. The air exit erection joint of draught fan 6 is to the outdoor chimney 2 of factory building, 2 surperficial circumferences of chimney that are located the factory building inboard and are close to the factory building top set up inlet port 3 more than two, 2 inboard welded mountings of chimney that are close to inlet port 3 below taper pipe 4 with higher speed, the little one end of 4 trompils of taper pipe is up with higher speed, rain-proof cap 1 of leg mounting is passed through on 2 tops of chimney, draught fan 6 produces negative pressure suction, the dirty gaseous filtration formation clean gas through dust remover 5 that will handle in the process of the preceding road, upwards discharge the factory building top through chimney 2. An accelerating taper pipe 4 is arranged at the chimney section close to the top of the factory building, and air inlet holes 3 are uniformly distributed on the periphery of the chimney. According to the Venturi jet principle, after clean gas with high flow velocity in the chimney 2 passes through the accelerating taper pipe 4, the wind speed is further enhanced, so that a low-pressure area is formed around the air inlet hole 3, dirty air and heat at the top of a workshop are sucked into the chimney 2 and discharged outdoors, the air in the workshop is purified, and the energy consumption is also saved.
