(5) ДИСТАНЦИОНИРУЮЩЛЯ РЕШЕТКА ТЕПЛООБМЕННОГО АППАРАТА(5) REMOTE GRID OF A HEAT EXCHANGE EQUIPMENT
Изобретение относитс к тепло- энергетике, а именно к дистанционирующим решеткам теплообменных аппаратов , и может быть использовано в теплообменной аппаратуре.The invention relates to heat and power engineering, in particular to spacer grids of heat exchangers, and can be used in heat exchange equipment.
Известны диетанционирующие решетки теплообменных аппаратов, содержащие разъемный обод с планками, выполненными из материала с меньшей прочностью на истирание, чем материал труб 1 )Known dieting grids of heat exchangers containing a split rim with straps made of a material with lower abrasion resistance than the material of the pipes 1)
Недостатком известных решеток вл етс быстрое изнашивание дистанционирующих . планок, что приводит к усилению вибрации труб и повышенному их износу.A disadvantage of the known grids is the rapid wear of the spacers. strips, which leads to increased vibration of pipes and increased wear.
Цель изобретени - снижение износа планок и повышение долговечности The purpose of the invention is to reduce wear of the slats and increase durability.
труб.pipes.
Поставленна цель достигаетс тем, что решетка дополнительно содержит вкладыши из фторполимера, а планки выполнены с пазами под вкладыши, выступающие по обе стороны планок.The goal is achieved by the fact that the lattice additionally contains fluoropolymer liners, and the slats are made with slots for liners protruding on both sides of the slats.
На фиг. 1 изображена предлагаема , дистанционирующа решетка, общий вид; на фиг. 2 - планка с пазом; на фиг.З - раз рез А-Анафиг.2; на фиг. k - вкладыши; . на фиг. 5 - планка с вкладышем; на фиг. 6 - разрез Б-Б на фиг. 5Дистанционирующа решетка теплообменного аппарата содержит разъемный обод 1 с планками 2, выполненными с пазами 3 под вкладыши , из фторполимера (например, из фторопласта , тефлона и др.).FIG. 1 depicts the proposed, spacer grid, general view; in fig. 2 - bar with groove; on fig.Z - time cut A-Anafig.2; in fig. k - liners; . in fig. 5 - strip with liner; in fig. 6 is a section BB in FIG. The distance grille of the heat exchanger contains a detachable rim 1 with strips 2, made with grooves 3 for liners, of fluoropolymer (for example, of fluoroplastic, teflon, etc.).
Обод 1 ст гиваетс болтами 5. Планки 2 смежных решеток расположены под углом друг к другу и образуют ромбические чейки дл труб. Паз 3 выполнен в середине планки 2, примерно на 1/8 длины от ее концов, а вкладыш , установленный в нем, выступает The rim 1 is bolted 5. The bars of the 2 adjacent gratings are angled to each other and form rhombic tube cells. The groove 3 is made in the middle of the strap 2, about 1/8 the length of its ends, and the liner installed in it, stands
20 по обе стороны планки 2 на величину примерно 1/10 толщины планки 2.20 on both sides of the plank 2 by approximately 1/10 of the thickness of the plank 2.
