Description
本發明係有關一種可於爐內去除蓄熱磚堵塞物之蓄熱式焚化爐及去除方法，尤指一種於焚化爐停機進行排汙，乃自各蓄熱槽底部導入堵塞物吹除氣流，而將蓄積於該蓄熱槽最上層蓄熱磚上表面之堵塞物，經由相對燃燒室所形成之排汙口吹除之設計者。The invention relates to a regenerative incinerator and a removal method capable of removing a blockage of a heat storage brick in a furnace, in particular to a sewage discharge in an incinerator, which is introduced from a bottom of each heat storage tank to blow off a gas flow, and will accumulate in The blockage of the upper surface of the uppermost heat storage brick of the heat storage tank is blown off by a designer who blows off the sewage outlet formed by the combustion chamber.
按，生産中廣泛應用的有機溶劑，在室溫下易揮發成氣體，故又名揮發性有機物(Volatile Organic Compounds，VOCs)，而多數的VOCs對人體有一定毒性，必須加以處理；而VOCs可採用蓄熱焚化爐(Regenerative Thermal Oxidizer，RTO)予以焚化，［圖1〕所示為常見之雙槽式蓄熱焚化爐10，其於內部堆疊有蓄熱磚14之第一與第二蓄熱槽11、12之間連結燃燒室13，並將一氣流控制裝置20之進氣管21與排氣管22連結至各該蓄熱槽11、12，而該氣流控制裝置20根據所設定之切換時間，切換氣流於該第一與第二蓄熱槽11、12之流向，俾於第一與第二蓄熱槽11、12輪替進行進氣預熱與排氣蓄熱之程序。According to the widely used organic solvents in production, they are easily volatilized into gases at room temperature, so they are also known as Volatile Organic Compounds (VOCs). Most VOCs are toxic to humans and must be treated. VOCs can be used. It is incinerated by a Regenerative Thermal Oxidizer (RTO). [Fig. 1] shows a common double-tank type thermal storage incinerator 10 in which first and second heat storage tanks 11 and 12 of heat storage bricks 14 are stacked. The combustion chamber 13 is connected between the intake pipe 21 and the exhaust pipe 22 of the air flow control device 20, and the air flow control device 20 switches the air flow according to the set switching time. The flow of the first and second heat storage tanks (11, 12) alternates between the first and second heat storage tanks (11, 12) for the intake preheating and exhaust heat storage.
次按，若蓄熱焚化爐所處理之氣體中有含矽有機物(HMDS或矽油等矽化物)，因含矽有機物經高溫氧化後之衍生物為二氧化矽(SiO2 )，而二氧化矽粉末會因第一與第二蓄熱槽11、12輪替進行進氣預熱與排氣蓄熱之程序，逐漸蓄積於最上層蓄熱磚之上表面進而堵塞，及蓄熱槽產生產生偏流而致使氣流不穩定與局部過溫問題；然而，習知去除蓄熱磚堵塞物之方法，係將蓄熱磚自蓄熱槽中取出，而於焚化爐外部將蓄熱磚上之堵塞物去除，不但必須耗費搬運時間及人力，且因蓄熱磚之結構強度較差，容易在取放之過程中造成蓄熱磚之結構不完整，結構不完整之蓄熱磚乃無法再堆疊於蓄熱槽中，不堪再使用。Sub-press, if the gas treated by the regenerative incinerator contains organic matter (HMDS or bismuth oil), the derivative of cerium-containing organic matter after high temperature oxidation is cerium oxide (SiO 2 ), and cerium oxide powder The first and second heat storage tanks 11 and 12 alternately perform the procedures of intake air preheating and exhaust heat storage, and gradually accumulate on the upper surface of the uppermost heat storage brick to block, and the heat storage tank generates a bias current to cause the airflow to be unstable. However, the conventional method of removing the blockage of the heat storage brick is to remove the heat storage brick from the heat storage tank, and remove the blockage on the heat storage brick outside the incinerator, which not only requires time and manpower. Moreover, due to the poor structural strength of the heat storage brick, it is easy to cause the structure of the heat storage brick to be incomplete during the process of picking up and discharging, and the heat storage brick with incomplete structure can no longer be stacked in the heat storage tank, which is unusable.
本發明之主要目的，係欲解決先前技術必須於焚化爐外部去除蓄熱磚堵塞物之問題，而具有可於焚化爐內部去除蓄熱磚堵塞物之功效。The main object of the present invention is to solve the problem that the prior art must remove the blockage of the heat storage brick outside the incinerator, and has the effect of removing the blockage of the heat storage brick inside the incinerator.

And forming a drain outlet with respect to the combustion chamber, connecting an intake pipe and an exhaust pipe of a gas flow control device to each of the heat storage tanks, and connecting an external air introduction pipe to the intake pipe or each of the heat storage slots a bottom portion; thereby, when the incinerator is in operation, the airflow control device exhausts the intake air and the exhaust pipe by the intake pipe and switches the incineration gas flow and the incineration gas flow according to the set switching time. The flow direction of the heat storage tank; when the incinerator is shut down, the air flow control device blows out the airflow to each of the heat storage tanks through the external air introduction pipe and the air intake pipe, and accumulates in each of the heat storage tanks The blockage on the upper surface of the upper heat storage brick is blown off through the drain port.
此外，該排汙口為原有之維修口，該排汙口設置有過濾網；又，進一步於各該蓄熱磚之上堆疊層與下堆疊層之間設置有墊片，而該墊片為薄小之蓄熱磚。In addition, the sewage outlet is an original maintenance port, and the sewage outlet is provided with a filter net; further, a gasket is further disposed between the stacked layer and the lower stacked layer on each of the heat storage bricks, and the gasket is Thin small heat storage bricks.
再者，本發明可於蓄熱式焚化爐爐內去除蓄熱磚堵塞物之方法，係相對焚化爐之燃燒室形成有排汙口，而於焚化爐停機時，***化爐之蓄熱槽底部導入堵塞物吹除氣流，用以將蓄積於蓄熱槽最上層蓄熱磚上表面之堵塞物經由排汙口吹除；其中，將經由排汙口吹除之堵塞物加以過濾。Furthermore, the present invention can remove the blockage of the heat storage brick in the regenerative incinerator furnace, and form a sewage outlet in the combustion chamber of the incinerator, and when the incinerator is shut down, the bottom of the heat storage tank of the self-incinerator is blocked. The airflow is blown off to blow off the blockage accumulated on the upper surface of the uppermost heat storage brick of the heat storage tank through the sewage outlet; wherein the plugged material blown out through the sewage outlet is filtered.
首先，請參閱［圖2〕、［圖3〕所示，本發明可於爐內去除蓄熱磚堵塞物之蓄熱式焚化爐30，係於至少兩蓄熱槽(也就是說至少各一蓄熱區與放熱區)31、32之間連結一燃燒室33，而於各該蓄熱槽31、32內部堆疊有蓄熱磚34，且相對該燃燒室33形成有排汙口35，該排汙口35可為新增或是利用原有之維修口，而進一步於該排汙口35設置有過濾網36；並將一氣流控制裝置40之進氣管41與排氣管42連結至各該蓄熱槽31、32，另將一外氣導入管43連結於該進氣管41或各該蓄熱槽31、32底部。藉此，當焚化爐燃燒運轉時(如［圖2〕所示)，該氣流控制裝置40藉由該進氣管41進氣與該排氣管42排氣且根據所設定之切換時間，切換待焚化氣流與已焚化氣流於該各該蓄熱槽31、32之流向；另當焚化爐停機排汙時(如［圖3〕所示)，該氣流控制裝置40則可藉由該外氣導入管43與該進氣管41逐一或同時導入堵塞物吹除氣流至各該蓄熱槽31、32，而將蓄積於各該蓄熱槽31、32最上層蓄熱磚34上表面之堵塞物經由該排汙口35吹除，排出焚化爐外部。First, referring to [Fig. 2] and [Fig. 3], the regenerative incinerator 30 capable of removing the blockage of the heat storage brick in the furnace is attached to at least two heat storage tanks (that is, at least one heat storage area and A combustion chamber 33 is connected between the heat release zones 31 and 32, and a heat storage brick 34 is stacked inside each of the heat storage tanks 31 and 32, and a sewage outlet 35 is formed with respect to the combustion chamber 33, and the sewage outlet 35 can be Adding or using the original maintenance port, and further providing a filter net 36 to the sewage outlet 35; and connecting the intake pipe 41 and the exhaust pipe 42 of the air flow control device 40 to each of the heat storage slots 31, 32. An external air introduction pipe 43 is connected to the intake pipe 41 or the bottom of each of the heat storage grooves 31 and 32. Thereby, when the incinerator is in operation (as shown in [Fig. 2]), the airflow control device 40 is exhausted by the intake pipe 41 and the exhaust pipe 42 and switches according to the set switching time. The flow of the incineration gas stream and the incineration gas stream in the heat storage tanks 31, 32; and when the incinerator stops the sewage discharge (as shown in [Fig. 3]), the air flow control device 40 can be introduced by the external air The tube 43 and the intake pipe 41 are introduced into the blockage blow airstream one by one or at the same time to the respective heat storage tanks 31, 32, and the blockages accumulated on the upper surface of the uppermost heat storage block 34 of each of the heat storage tanks 31, 32 are passed through the row. The sewage 35 is blown off and discharged to the outside of the incinerator.
接著，請參閱［圖4〕所示，由於各該蓄熱磚34內部僅有可縱向流動之氣流通道，故進一步於各該蓄熱磚34之上堆疊層與下堆疊層之間設置有墊片341，而該墊片341可為薄小之蓄熱磚，致使各該蓄熱磚34之堆疊層間留有間隙，增加氣流橫向流動之可能性，改善單一蓄熱磚一旦堵塞就整個縱向氣流通道失效之問題。Next, as shown in FIG. 4, since each of the heat storage bricks 34 has only a longitudinally flowable air flow passage, a spacer 341 is further disposed between the stacked layer and the lower stacked layer on each of the heat storage bricks 34. The spacer 341 can be a thin heat storage brick, so that a gap is left between the stacked layers of the heat storage bricks 34, which increases the possibility of lateral flow of the airflow, and improves the problem that the entire longitudinal heat flow brick fails once the single heat storage brick is blocked.
基於如是之構成，本發明可於焚化爐停機進行排汙，乃自各該蓄熱槽31、32底部導入堵塞物吹除氣流，而將蓄積於各該蓄熱槽31、32最上層蓄熱磚34上表面之堵塞物，經由相對該燃燒室33所形成之排汙口35吹除，而具有可於焚化爐內部去除蓄熱磚堵塞物之功效；再者，進一步於各該蓄熱磚34之上堆疊層與下堆疊層之間設置墊片341之設計，因可改善單一蓄熱磚一旦堵塞就整個縱向氣流通道失效之問題，可於較大面積產生堵塞現象時，再進行堵塞物去除之程序，則具有延長蓄熱磚堵塞物去除週期之功效。Based on the configuration, the present invention can stop the sewage in the incinerator, and introduce a plugging blowdown gas from the bottom of each of the heat storage tanks 31, 32, and accumulate on the upper surface of the uppermost heat storage brick 34 of each of the heat storage tanks 31, 32. The blockage is blown off through the drain port 35 formed by the combustion chamber 33, and has the effect of removing the blockage of the heat storage brick inside the incinerator; further, stacking layers on each of the heat storage bricks 34 and The design of the spacer 341 is arranged between the lower stacked layers, because the problem that the entire longitudinal heat flow passage fails once the single heat storage brick is blocked can be improved, and the blockage phenomenon can be generated when the blockage phenomenon occurs in a large area, and the program for removing the blockage is extended.
