電熱水鍋爐http://m.ydjsh.cn/房的鼓風(fēng)機(jī)和引風(fēng)機(jī)噪聲一般在90分貝左右，因輸送的熱水鍋爐煙氣溫度高達(dá)180度，采用封閉隔聲會(huì)導(dǎo)致散熱不良，電機(jī)溫度過(guò)高，甚至燒毀電機(jī)。那么電熱水鍋爐風(fēng)機(jī)噪音應(yīng)該如何解決呢？
對(duì)電熱水鍋爐房的工藝布置保持小變，將鼓風(fēng)機(jī)、引風(fēng)機(jī)分別置在隔聲室內(nèi)，用通風(fēng)管將它們與主機(jī)相連接，在隔聲室頂上或墻而上開(kāi)設(shè)進(jìn)氣日，并安裝消聲器供機(jī)房進(jìn)風(fēng)使用。平而布置時(shí)將鼓風(fēng)機(jī)靠近鍋爐房一側(cè)，進(jìn)風(fēng)日在上風(fēng)側(cè)，電機(jī)置于氣流通道中間。鍋爐運(yùn)行時(shí)，由于鼓風(fēng)機(jī)在隔聲室內(nèi)產(chǎn)生負(fù)壓，大量的室外新鮮空氣就會(huì)自動(dòng)進(jìn)入隔聲室，首先和引風(fēng)機(jī)電機(jī)進(jìn)行熱交換，使之冷卻降溫，室內(nèi)溫度保持500C左右。該方案中由于隔聲室和進(jìn)風(fēng)消聲器的降噪能力都比較大，降噪的效果容易實(shí)現(xiàn)。鼓風(fēng)機(jī)將預(yù)熱的空氣送入鍋爐燃燒，回收利用能源，具有一定的經(jīng)濟(jì)效益。
For electric water boiler room to keep small change process layout, the blower, Fan noise respectively, set in the room, with a ventilation pipe connected to their hosts, soundproof room at the top or on the wall and open the intake date, and installation muffler inlet for the engine room use. The blower near the boiler room to one side flat and arranged into the wind at the windward side of the day, the motor placed in the middle of the air flow channel. Boiler operation, due to the negative pressure in the acoustic indoor blower, lots of fresh outdoor air will automatically enter the acoustic chamber, the first and induced draft fan motor heat exchange, so that cool-down, keep the indoor temperature of about 500C. The program due acoustic chamber and inlet muffler noise reduction capabilities are large, easy to implement noise reduction effect. Blowers preheated combustion air into the boiler, recycling energy, with certain economic benefits.
為保證治理效果和電熱水鍋爐http://m.ydjsh.cn/設(shè)備正常運(yùn)行，在設(shè)計(jì)施工中，應(yīng)根據(jù)具體要求，考慮噪聲的聲強(qiáng)、聲頻等因素，對(duì)隔聲、吸聲和通風(fēng)散熱進(jìn)行詳細(xì)設(shè)計(jì)，做好細(xì)部處理。對(duì)隔聲室的大小厚度，吸聲材料的種類、厚度進(jìn)行計(jì)算。進(jìn)風(fēng)消聲器的消聲量一般選25dB的鋼絲網(wǎng)水泥粉刷，將玻璃纖維棉固定在鋼板上，吸收隔聲室內(nèi)的混響噪聲。
To ensure the effectiveness of governance and electric water boiler equipment uptime, during design and construction, should be based on the specific requirements, consider the noise sound intensity, audio and other factors, sound insulation, sound absorption and ventilation detailed design, good detail treatment. The thickness of the insulation chamber size, the type of sound-absorbing material, the thickness calculated. Muffler inlet muffler general election 25dB of ferro-cement stucco, glass fiber cotton fixed on the plate, absorbing acoustic noise reverberation chamber.
